Chapter 63: Dao Heart Demon Cultivation Dafa

In the imperial city, the shouting of killing shook the sky, and it was completely chaotic.

Tens of thousands of forbidden troops rebelled, and under the leadership of a group of people from the rivers and lakes, they rushed in the direction of the palace, to break through the city gate, to overthrow the Ming court, and change the dynasty.

This terrible turmoil even spread to the entire capital.

Many people who were originally around the palace and were ready to watch the excitement immediately scattered in fright after seeing the turmoil of the forbidden army, hiding in their homes and closing their doors, not daring to join in the fun.

In the middle of the street, only a series of powerful figures swept towards the palace and went to reinforcements.

And in the palace.

Yu Huatian led a group of equally terrifying masters and slowly walked out of the Taihe Palace.

This turmoil, from beginning to end, was under his control.

He's just waiting.

Wait for all the enemies to appear!

The Ming Dynasty has been in turmoil for too long.

This time, he wants to wipe out this group of rebellious ministers and thieves!

Pedal Pedal Pedal ~

The sound of crisp footsteps resounded through the square.

Yu Huatian's face was indifferent, holding the Heavenly Sword in his hand, and he walked slowly.

Behind him, there were hundreds of masters, and their momentum was no less than that of the Blue Dragon Society and the Demon Palace.

Three of them are even comparable to top grandmasters such as Yang Yanyu and Di Qinglin.

These three people are Zhang Sanfeng, the founder of Wudang, Luo Qingyang, the 'Lone Sword Immortal' of Muliang City Lord, and Zhao Yuzhen, the 'Dao Sword Immortal' of the Qingcheng Mountain Palm Sect.

In addition, there are several people who are not weak.

For example, a white-haired, cold-eyed, white-haired witch with a long sword in her hand, and a man in black with a strange weapon.

The black-clothed man's name was Zhan Yu, nicknamed 'Spear Shovel Double Fly', and his weapon was a spear, but the other end was a shovel, which was extremely strange.

Zhan Yu is the same as the master of the Ten Evil Villages, Tan Yingshou and Mo Yixian, the master of the Xiaoyao Gate, and he is also a strong person on the 'black list'.

Behind Lian Nishang and Zhan Yu, there are several masters who are not weak, all of whom are great grandmasters.

During this time, the Blue Dragon Society and the Demon Palace were gathering the strong, but Yuhuatian was not idle.

These people behind him are the masters he has subdued from the rivers and lakes during this time.

Coupled with Ye Gucheng, Lei Hong, Lian Chengbi, Yan Shisan, Murong Qiudi, Cao Zhengchun and others, the masters under his command at this moment are no longer weaker than the side of the Blue Dragon Society and the Demon Palace.

And that's not all he has to offer!

"It's all here, it's good!"

Yu Huatian walked to Zheng He and the others, looked at Fang Yeyu and Yang Yanyu and the others opposite, his face was indifferent, and he said slowly.

Fang Yeyu frowned and said, "You didn't go to Shanhaiguan?!" ”

Yu Huatian said calmly: "If this seat doesn't pretend to leave Beijing, how can it attract you group of ghosts and spirits here and catch them all?" ”

On the Shanhaiguan side, the situation is indeed very critical.

But with Sun Chengzong and Yang Sichang going, they can hold out for a while.

The only problem is that the group of Qing martial arts masters is indeed a bit tricky.

But compared with the two, Yu Huatian still felt that the threat of the Demon Palace and the Blue Dragon Society was greater.

So he asked Zhu Youxiao to set the canonization ceremony half a month later.

He was betting that the Blue Dragon Society and the Wizard Palace would do it at this canonization ceremony.

If the Blue Dragon Society and the Demon Palace don't do anything, then he can only go to Shanhaiguan first to help Sun Chengzong and Yang Sichang block the martial arts masters in the Qing army.

How can the Qinglong Society and the Wizard Palace do it, so just take this opportunity to wipe out this group of ghosts and ghosts, and completely solve the internal problems of the Ming Dynasty!

And as it turned out, he was right!

This group of ghosts and ghosts really chose to do it at the canonization ceremony, so it was not in vain that he had been preparing for so long!

"Humph! Arrogant! ”

Leng Yan snorted coldly: "What if you don't leave? Just take this opportunity to get rid of Ling, a yin and yang person, so as not to cause trouble in the future! ”

Hermaphrodite?

Yu Huatian's eyes narrowed slightly, the person who dared to call him like this last time had already grown grass on the grave.

"Don't talk nonsense with him, take advantage of the day when Master Sun En is dragged, take action as soon as possible and solve them!"

Yang Yanyu said in a deep voice, for some reason, looking at Yuhuatian's calm face, he always felt a little uneasy in his heart.

Regardless of Yuhuatian's terrifying strength of Baili Dongjun and Fang Longxiang, who could kill the Great Grandmaster's Consummation Realm, it was Zhang Sanfeng and the two peerless swordsmen behind him, and their aura was also very terrifying.

If it dragged on, he feared that something else would happen.

"Do it!"

Fang Yeyu and the others also understood this truth, and without further ado, they burst out one after another and rushed out towards Yuhuatian and the others.

In an instant, the powerful aura of the Dao swept through the heavens and the earth, like ten thousand beasts galloping, and the powerful momentum overwhelmed the many forbidden troops and brocade guards in front of the altar couldn't help but retreat, their faces were shocked.

Only Yu Huatian, Zheng He and others are not afraid of this might.

Looking at the dense crowd in front of him, Yu Huatian looked indifferent, slowly raised the Heavenly Sword in his hand, and gently moved forward: "Kill!" ”

Kill!

In an instant, everyone rushed out in an instant.

The scuffle erupted in an instant.

Yu Huatian ignored the others, he pulled out the Heavenly Sword and rushed straight towards Fang Yeyu, who was the leader.

The second son of this Demon Palace has a similar personality to the previous eldest dragon of the Blue Dragon Society, Yu, and he is the sixth child.

Yuhuatian hates such people extremely much.

In particular, this person was the main planner of this unrest.

Therefore, in this battle, others can ignore it, but this side of the night feather will die!

It's just that last time in Tianning Temple, Fang Yeyu witnessed Yuhuatian kill three top grandmasters in a row, such as Baili Dongjun, Fang Longxiang, and Bai Xiaosheng, and he only had a mere triple realm of great grandmasters, where would he dare to fight Yuhuatian.

Seeing that Yu Huatian's eyes had been staring at him, Fang Yeyu's heart trembled, as if he was being targeted by some kind of desolate beast, his scalp was numb, and then he didn't think about it, and immediately dodged and hid in the crowd.

Yu Huatian sneered, chased after him with his sword, locked Fang Yeyu's position in an instant, and then stabbed out towards him.

Feeling the fierce sword momentum coming from behind him, Fang Yeyu's face was horrified, and he immediately shouted, "Senior brother, save me!" ”

Laugh at!

A cold light rushed out from the side, also with a good majesty.

This is a strange weapon, like a sword not a sword, like a spear not a spear, but very slender and sharp, it is the 'Yin Wind' strict stinger.

Boom –

The two momentum collided, and Yu Huatian's sword momentum was blocked, but Leng Yan was also repelled several steps by this powerful sword momentum.

After stabilizing his figure, he looked at the murderous figure opposite with a solemn face, and said in a deep voice: "Step aside!" ”

When Fang Yeyu heard this, he hurriedly burrowed into the crowd and disappeared.

And Leng Yan's eyes have been staring at Yuhuatian.

But the moment Fang Yeyu disappeared, Yuhuatian also disappeared.

"Not good!"

Leng Yan was shocked, he didn't expect that Yuhuatian would be so persistent in killing Fang Yeyu.

But at this time, he didn't have time to think about it, he immediately dodged in front of the afterimage in front of him, and stabbed out the god-snatching thorn in his hand without hesitation.

But the next moment, a terrifying force struck from the front, Leng Yan's body trembled, let out a muffled snort, and the whole person was directly shocked back dozens of feet away, and hit many nearby figures in a row.

Immediately after, a scream suddenly came from the crowd.

It was Fang Yeyu's voice!

Leng Yan looked back, and his eyes immediately cracked.

I saw a figure fly up from the crowd, vomiting blood and retreating, before he could land, a white shadow had already appeared in the air, the sword qi like a silver moon slashed, and a good head rose to the sky, blood sprinkled all over the sky!

"Senior brother!"

Leng Yan roared angrily, then jumped deeply, and the whole person directly killed the white shadow in mid-air.

"Second son!!"

The masters of the Demon Palace were also shocked, and they rushed in that direction one after another, their faces pale.

Fang Yeyu was Lord Demon's favorite disciple, and his status in the Demon Palace, even above the eldest prince Leng Yan, was now dead like this.

Once the magician is out, he will inevitably go berserk!

Everyone suddenly burst into murder and rushed out in anger, wanting to kill Yuhuatian and avenge Fang Yeyu.

[Qi luck from Fang Yeyu +55555.] 】

Listening to the system prompt ringing in his head, Yu Huatian exhaled lightly, comfortable!

Immediately, he turned around and looked at the angry figures rushing in all directions, and the murderous intent in his eyes reappeared!

Sa~

In the next second, he disappeared in an instant.

Then, the screams in the crowd rang out one after another, and the blood-stained heads soared into the sky.

At the same time, the system prompt in my head is also sounding densely:

[Luck from Huang Zhan +6700.] 】

[Luck from Wang San +1287.] 】

[Luck from Zhan Xiao +15302.] 】

[Luck from the White Mountain +10996.] 】

This time, all the masters under his command participated in the battle, and with the help of Zheng He and others, the gap between the top masters of the two sides was not very large, so he didn't want to stare at the enemy's top masters anymore, it would be too much of a waste of time.

With his strength at the moment, killing ordinary great grandmasters is like slaughtering pigs and dogs, and the so-called masters below the great grandmaster have no one who can take him a move and not die, so Yu Huatian plans to deal with some of the enemy's ordinary grandmasters and grandmaster-level masters first, and reduce the pressure on some ordinary masters on the side of the imperial court.

In the blink of an eye, more than twenty masters above the Grandmaster died in his hands.

Leng Yan and the others were stunned, but they couldn't catch Yuhuatian's figure at all, his speed was too fast!

But if you don't stop him and let him kill him like this, the people in the Demon Palace will die.

You must know that among these people, there are many geniuses of the Demon Palace, as long as they are given enough time for them to grow up, they will also have the opportunity to break through the Great Grandmaster in the future and become the foundation of the Demon Palace.

"Red face and white hair, intercept him!"

Leng Yan roared, he quickly made a decision, he couldn't let Yuhuatian continue to kill like this.

In the distance, Liu Shaozhi and Hua Jieyu, who were fighting with the two Great Grandmasters of the Ghost King's Mansion, heard this, and immediately abandoned their opponents and turned towards Yuhuatian to kill.

Yu Huatian's eyes narrowed slightly, without any fancy, and he stabbed straight with a sword.

Boom –

The huge sword momentum exploded, Liu Shaozhi and Hua Jieyu's bodies shook, and the two of them retreated in unison, looking at Yuhuatian with a shocked expression.

You must know that both of them are Great Grandmaster Sevenfold Realm, and under the joint action, even the powerhouses of the Great Grandmaster Ninefold Realm dare to fight.

But now he can't stop Yuhuatian's sword, which is enough to show how terrifying Yuhuatian's strength is at this time!

The most important thing is that, according to the information they have, this Yuhuatian is only in his early twenties!

At such an age, he has such terrifying strength, if he is given another ten years, no, five years!

If you give him another five years, how far will he grow?!

This son's martial arts qualifications are terrifying!

No wonder the second prince did not hesitate to use the power of the border to transfer this person out of the capital.

It's a pity that the second son is also dead at this moment......

The two pondered, but Yu Huatian didn't give them time to think, a sword repelled the two, Yu Huatian rushed out again, the powerful sword momentum on his body rose, he wanted to kill these two protectors of the Demon Palace first!

But at this moment, a sharp sound of breaking wind suddenly came from behind him, and it was strict!

Yu Huatian didn't want to think about it, and when he turned around, he slashed out with a sword!

Boom –

With a loud bang, Leng Yan was knocked back more than a dozen steps again, and Yuhuatian also took two steps back.

As the chief disciple of the Demon Master Pang Ban, this Leng Yan's strength is still extremely strong, and he has already reached the Ninefold Realm of the Great Grandmaster!

Leng Yan was also very shocked in his heart, but he didn't have time to think about it at this time, stabilized his figure, and shouted at Liu Shaozhi and Hua Jieyu: "Let's go up together, lift his head back, otherwise you will all die!" ”

He knew how high Fang Yeyu's status was in his master's heart.

Fang Yeyu not only has strong martial arts qualifications, but also works scheming, and has the qualifications to become a hero.

It can be said that the magician Pang Ban cultivated him as a successor.

And now he died at the hands of Yuhuatian.

If he didn't bring Yu Huatian's head back, he wouldn't be able to explain to his master at all!

When Liu Shaozhi and Hua Xie heard this, their hearts were slightly cold, and they didn't say much, and immediately dodged and killed towards Yuhuatian.

Boom boom boom~

The three Great Grandmasters, comparable to the powerhouses of the Nine Realms of the Two Great Grandmasters, joined forces to kill the Yuhua Field, and the power in the field shook the sky in an instant, and the terrifying qi of the Dao Dao spread in all directions, shaking back many masters below the Great Grandmaster in the vicinity.

Yu Huatian's eyes were indifferent, he didn't say a word, wherever he thought about it, his qi moved with his heart, and a layer of golden qi instantly appeared on his body.

Innate and indestructible!

The next moment, he cast a variety of divine actions, like a loach slashing through the crowd, dodging the attacks of the willow shaking branch and Hua Jieyu, and then his eyes were cold, and he slashed straight at the 'Yin Wind' that was attacking directly in front of him:

"Since you want to die, then I will send you down to accompany that sixth child first!"

Boom –

A terrifying sword momentum erupted, forming a sword aura that was filled with vitality, destruction, death, killing, and brilliance...... All kinds of momentum fell straight towards the top of Leng Yan's head.

Heavenly Sword Slash!

Leng Yan's pupils narrowed drastically, and the pores all over his body were emanated, and he felt the terrifying power contained in this sword.

But at this moment, it was too late to hide, Leng Yan could only grit his teeth, his face was hideous, he mobilized his true qi, and he also stabbed forward!

Sa –

It was also a terrifying blow, a stab of anger from the Great Grandmaster's Nine Realms!

However, as soon as this vast true qi swept out less than three meters, it was annihilated inch by inch in the overwhelming sword qi, turning into spiritual energy and dissipating.

After smashing this attack, the power of the sword qi was mostly weakened, but some of it still fell down, drowning Leng Yan.

Rumble!

There was a loud bang, the masonry on the ground exploded, the wind roared, and then a blood-stained figure flew out of it, and the person was in mid-air, and blood spurted wildly from his mouth.

It's Leng Yan!

This sword directly broke his body protection qi, constantly slashed his body to pieces, and also cut off his internal organs and displaced, at this moment the meridians in his body were in severe pain, and he had obviously suffered serious internal injuries.

"The eldest son!"

Liu Shaozhi and Hua Xie Yu were shocked, and immediately dodged and rushed out, attacking Yuhua Tian, who was about to continue to attack.

The second son is already dead, and if the eldest son is also dead, they will really be gone.

Even if they return alive, the Wizard will never let them go!

Thundered~

The powerful aura swept in, but Yu Huatian ignored it, and cast a variety of divine actions, flashing from the side in an instant, dodging the attack of the two, and then continued to kill Leng Yan with his sword.

Take advantage of your illness to kill you!

Yuhuatian will not wait for him to recover and flee or continue to attack him.

Cutting the grass is to get rid of the roots!

His speed was too fast, and it was too late for Liu Shaozhi and Hua Xie Yu to stop him, mainly because they couldn't catch up, so he immediately lost his color and shouted: "Be careful!" ”

Leng Yan looked at the imposing Yuhuatian, his face was pale, he also knew that Yuhuatian had murderous intentions towards him, such a person was like a dog, once he was targeted, he would definitely not die.

Fang Yeyu just now, the same is true for him at this moment!

But he was hit by Yuhuatian's strongest sword, and at this moment, his meridians were in severe pain, and his true qi could not be mobilized, and he was powerless in the face of Yuhuatian's attack.

And the speed of Yuhuatian is too fast, like a ghost, he can't hide.

In that case, then die!

A trace of cruelty flashed in Leng Yan's eyes, and he suddenly took out a black bead from his arms and threw it towards Yuhuatian!

However, before throwing it, he ignored the severe pain in the meridians and forcibly injected a trace of true qi into the bead.

Boom –

With the injection of this trace of true qi, the black light on the bead instantly became large, and the air flow like yin qi wrapped the bead and spread out from mid-air.

Unlike other celestials, his master Pang Ban does not cultivate weapons, but practices an extremely strange magic skill, called 'Dao Heart Demon Seed Dafa', so there is no treasure like Li Changsheng's Immortal Sword or Bai Yujing's Immortal Sword Technique, and the only thing that has it is this bead.

This bead is a foreign body, which contains the three-percent demon yuan of his master demon master Pang Ban, which is a means left by Pang Ban to save their lives, and Fang Yeyu also has one, but just now, I don't know if it was because I didn't think about it in a panic or didn't have time to use it, Fang Yeyu didn't use it.

And Leng Yan is different from Fang Yeyu, he always carries this bead on his body, the purpose is to save his life at a critical moment.

And now, it really comes in handy!

After throwing out the black bead, Leng Yan's eyes stared at the figure in front of him, and his heart was tightly raised.

If this bead can't hurt Yuhuatian, then he really can't do anything!

Boom –

When the beads rushed to a few feet in front of Yuhua Field, they exploded, and a terrifying momentum as vast as an abyss swept from it.

Yu Huatian's figure froze suddenly, his pupils narrowed, and a sense of crisis rose in his heart, he didn't expect Leng Yan to hide such a strange thing.

At the critical moment, he only had time to mobilize the true qi of his whole body to strengthen the defense of the innate immortal body, and then he was hit by a terrifying energy that swept in.

Thundered~

This energy is pervasive, and the innate indestructible body protection qi rumbles, blocking this energy out.

But in the next moment, a strange force suddenly entered Yuhuatian's body through the body protection qi.

In an instant, Yu Huatian's eyes widened, as if they were about to burst, his heart beat violently, the meridians of his body bulged, his face was full of green tendons, and he was obviously in an extreme pupil.

This strange force directly penetrated the innate immortal defenses and acted on his body, attracting his internal organs as if they were about to explode.

"Poof......

Yu Huatian finally couldn't help it, a trace of blood overflowed from the corner of his mouth, but this power was limited after all, and under the automatic operation of Sunflower Yin and Yang Longevity, this power was finally suppressed, and then gradually disappeared.

Bang –

Yuhuatian staggered to the ground, gasping for breath, and before he knew it, he was already sweating profusely, and his eyes were full of fear.

At that moment just now, he really felt that his internal organs were about to explode, and he felt like he was about to explode and die!

That strange power, it's terrifying!

The body protection qi prevented the power of the demon yuan, but it couldn't stop the strange power contained in it, and it actually acted directly into the body, attracting his internal organs, if he couldn't suppress that power, it would definitely be the end of exploding and dying!

"Is this the Dao Heart Demon Seed Dafa of the Demon Master Pang Ban?!"

A flash of horror flashed in Yu Huatian's eyes, it was the first time he had encountered such a strange attack method since he had crossed over.

This Heart Demon Seed Dafa is really worthy of the name of Demon Gong!

In the distance, Leng Yan saw that Yuhuatian had blocked the power of the black bead, and his face showed a look of disappointment, and he sighed in his heart.

This son is terrifying!

"The eldest son!"

At this time, Liu Shaozhi and Hua Xie Yu came to Leng Yan's side and looked at him with concern.

"Eldest Prince, are you alright?"

Leng Yan shook his head, looked at the tragic battlefield around him, a trace of unwillingness flashed in his eyes, and then gritted his teeth and said: "Withdraw!" ”

"What?"

Liu Shaozhi and the others were stunned for a moment.

"I say, withdraw!" Leng Yan roared angrily.

At this moment, he doesn't care whether this operation is successful or not, he just wants to live!

To be alive is to have hope!

Otherwise, even if this sky-changing operation is successful, he will make a wedding dress for the Blue Dragon Society, and he won't do such a stupid thing!

This time, Liu Shaozhi and the two heard it clearly, and they did not hesitate at the moment, and immediately took one left and one right, helped up Leng Yan, and were about to retreat to the edge of the battlefield.

But at this moment, a cold voice sounded from the front: "Go? When this seat does not exist? ”

Yuhua Field!

All three were shocked.

Leng Yan hurriedly shouted: "Retreat!" ”

As soon as he finished speaking, a figure had already swept in front of him, and the powerful sword momentum was like thunder splitting the sky, sweeping towards the three of them.

As soon as the faces of the willow shaking branches and Hua Jieyu changed, they immediately let go of the flute strictly, and their luck resisted.

The jade flute in Liu Shaozhi's hand bloomed with green and verdant light, and the power was shocking, turning into a light curtain to cover the sky.

The ribbon of colored clouds wrapped around Hua Jieyu's hand was stretched straight, like a sharp sword, wanting to break through the sword momentum and attack Yuhuatian.

The two attack and defend, and cooperate tacitly.

But the next moment, the sword momentum came, only to hear a loud 'boom', the green light curtain shattered, the jade flute cracked, and the colored cloud belt broke.

Immediately after, Liu Shaozhi and Hua Jieyu directly vomited blood and flew upside down.

A sword is seriously injured!

Snort –

The next moment, another sword slashed, as if a bright moon rose into the sky, and the sword immortal was in the sky, with a cold and piercing sword aura, slashing over the bodies of the two people.

The two of them were hit hard in an instant, they both let out a miserable scream, slammed the ground, the light under their eyes gradually dimmed, and their faces were shocked and unwilling, completely ending this brilliant life.

The last sword has completely shattered the vitality of the two!

[Luck from Willow Shake Branch +30565.] 】

[Luck from Hua Jieyu +32890.] 】

Yuhuatian indifferently put away his sword, didn't look at the corpses of the two, and walked straight to Leng Yan.

At this time, Leng Yan's face was pale, his expression was in a trance, looking at the figure in front of him, he smiled miserably, and said: "If you want to kill, you will kill, I will be defeated by you today, I admit it, but the master is ......"

Snort –

The sword flashed, slashing through Leng Yan's neck, and all sounds stopped abruptly.

Leng Yan's eyes widened, staring at Yuhuatian, his eyes full of disbelief.

"How can I listen to your nonsense!"

Yu Huatian glanced at him, turned around directly, and walked towards the battlefield in the distance.

In the rear, Leng Yan fell to the ground with a bang, and the vitality slowly dissipated.

When he was dying, a trace of remorse and unwillingness suddenly appeared in his eyes.

After decades of hard work, once it became empty, why bother, why bother......

[Luck from Lengyan +50800.] 】

Listening to the system prompt that sounded in his head, Yu Huatian also breathed a sigh of relief, so far, the main masters of the Demon Palace have been eliminated, and the Blue Dragon Society is left.

However, at this moment, there are still many masters of various factions left in the field, and these people can still get a lot of luck when they add up, and Yuhuatian does not intend to waste it.

Now that the opponent's masters are all contained, if you can kill one, count one!

Hmmm-

With a flick of his figure, Yuhuatian directly dodged into the crowd and turned on the "Brushing Qi Luck" mode again.

At this time, the predatory luck was the mainstay, and Yuhuatian did not waste time absorbing internal forces or the like.

Kill one more person, and one less person will die on his side.

Which is more important, you must be able to carry it clearly!

It's just that this time he hasn't been lucky for long, and an accident appears.

Yu Huatian frowned, stopped in the middle of the crowd, and looked ahead, his eyes cold.

There, a figure covered in sword qi as vast as the sea blocked in front of him.
