The Sword Dragon King technique can make each sword root the characteristics of the divine sword itself to form a specific dragon king.

For example, the Elephant Dragon Gem Sword is formed by the Jewel Armor Elephant Dragon King.

And this Demon Power True King Sword is formed by the Demon Power Dragon King.

You are a celestial-level divine weapon, and its edge is so strong that it is indestructible, enough to easily split a small mountain, and it does not need to consume the user's true qi, it is purely the power of the divine sword.

Now with Tang Long's domineering starry sky true qi.

Destroy miè killing grass and crack the ground.

A strong attack came in an instant, and the ten-meter huge body was for Cao Xiong, who was less than two meters away, that was to cover the sky and the sun.

Roar!

The Demon Dragon King swallowed it in one gulp.

Cao Xiong frantically danced the Thousand Grass Sword to attack, helplessly, this Demon Power Dragon King is essentially the Demon Power True King Sword, how could the same Celestial-level divine soldier be affected, and he was also directly devoured.

In this case, someone else would have been killed a long time ago, but Cao Xiong actually made a counterattack, breaking the dragon's mouth strongly, and the wolf escaped from it, while the Qiancao Sword in his hand was bitten by the dragon's mouth.

Cao Xiong gritted his teeth, gave up the Chigusa Sword, and fled again.

As soon as the person rushed out, Tang Long's attack was again.

Barbarian King Wrestling Swordsmanship!

The three-thousand-mile mountain and river sword was waved in his hand, and it turned into a hundred-meter giant sword and shot it directly.

This time, Cao Xiong was no longer able to resist, and he was powerless to dodge, seeing the giant sword falling, he roared fiercely: "Death will also pull your back, under the sea of purgatory grass, mysterious through the ages, now!"

He slammed his fists into the ground.

Rumble!

The giant sword fell, turning Cao Xiong into a blood mist.

Rumble!

The power that Cao Xiong sent out before he died destroyed countless murderous grasses, and even the earth was blasted open.

Tang Long's mind moved, and the Eight Stars used the Dao to cast it again, and the Starlight Prison formed locked the Thousand Grass Sword and the Demon Power True King Sword that had returned to its true colors, and he flew over and put away the two swords.

From now on, he will have two Celestial-level divine swords.

In his realm, when facing a battle, the celestial-level divine soldier can play a decisive advantage in turning the tide of battle.

At this moment, Xia Yulu also used the Purgatory Demon Ball to directly include Bi Hongming and Zhang Shaopin, and with the help of the coercion of the Purgatory Demon Ball, the Killing Grass did not dare to attack them at all, and easily came to Tang Long.

This is the first time that Xia Yulu and Tang Long have been able to help Tang Long since they reunited, which makes her very happy.

After inquiry, Tang Long learned that when Bi Hongming and Zhang Shaopin entered the city, they sensed some opportunities and jumped off the stone statue of the king dragon in advance, but they were attacked by the demon spirit clan and were transferred here.

In addition to them, there are many people who are trapped in the killing grass, and they have all reached the limit, and sooner or later they will be killed by the killing grass.

Tang Long had no intention of coming to the rescue, since he had entered the city, he should be ready to be killed.

His gaze fell on the blasted killing grass and the cracked ground.

In the eyes, it is all bones.

Human bones.

And in the rapid weathering, they all turned into bone meal and floated into the sky.

"Eternal mystery?"

Tang Long sounded Cao Xiong's madness before he died.

Beneath this sea of purgatory grass lies an eternal mystery.

Since it is an ancient mystery, it has to be traced back to tens of thousands of years ago, and the formation of the Lost Power City was established by the remnants of the Four Mighty Clans eight hundred years ago.

Looking at the sea of grass formed by this killing grass, Tang Long understood that the sea of purgatory grass should be deliberately covered up by the demon spirit clan.

The killer grass itself is a kind of killer grass that can only be grown by absorbing the breath of death, and this place is suitable for growing killer grass.

"I want to see what is hidden in this ancient mystery. ”

Tang Long pulled out the Starlight Guardian Battle Banner he was carrying and threw it out with shaking hands.

Bang!

The Starlight Guardian Banner is inserted in the center of this sea of purgatory grass.

The flagpole has a grass vine spirit shining on it, so that the killing grass will not attack it, and the magic fire on the guardian light shield formed by the battle flag itself plays a role.

The charm fire was not an ordinary flame, but once it fell on the killing grass, it immediately ignited a fire, and quickly spread out with the help of the strong wind here.

The sea of purgatory grass quickly died under this enchanting fire.

Those who still held out took the opportunity to quickly flee away from the area.

Bi Hongming and Zhang Shaopin shook their heads bitterly when they saw it in their eyes.

They fought desperately and were almost killed, but as a result, the place of death in their eyes, in Tang Long's hands, was not worth mentioning at all, and it was directly destroyed.

Especially Zhang Shaopin knew the origin of this starlight guardian battle flag, and he was even more shocked.

When the sea of purgatory grass was all burned, and even the ground was scorched, more than three hundred meters away from the Starlight Guardian Battle Banner, the ground cracked, revealing a swarthy hole, and looking around the hole, there were obvious traces of being blocked with boulders, obviously this should be the entrance to this ancient mystery.

Tang Long put away the Starlight Guardian Battle Banner and led the three of them to the entrance.

As soon as he arrived, a strange wave of power surged from the entrance of the cave.

Bi Hongming and Zhang Shaopin's faces changed at the same time.

"The power that affects the heart of martial arts!"

The two of them quickly retreated more than a hundred meters before the feeling subsided.

Tang Long and Xia Yulu stood still.

Tang Long, who has already achieved the will of the king, naturally doesn't even feel it, as if he doesn't have the power of zài.

But Xia Yulu didn't even have the slightest induction, it was very bland, which surprised Tang Long, he hadn't paid attention to Xia Yulu's martial arts heart before, and now he mobilized the will of the king to check, and Xia Yulu also opened his heart and did not stop it.

At this glance, Tang Long's eyes widened in shock.

"Half-step King's Will!"

Tang Long looked at Xia Yulu in surprise.

At this moment, Xia Yulu's martial arts heart was actually the same as before he killed Mo Wuzhen, which means that he was only half a step away from achieving the king's will.

"I don't want to be a burden to you. Xia Yulu said with a smile.

Tang Long's heart softened suddenly.

He has experienced the tempering of the heart of martial arts, and he knows best that the difficult journey.

But Xia Yulu has only been in retreat for more than a year, and she has done this, why?

As Xia Yulu said.

I don't want to be a burden to Tang Long.

In her more than a year of retreat, she was actually painfully sharpening her martial arts heart, and her martial arts heart was Tang Long, and she didn't want to be a burden to sharpen herself.

The martial arts heart of countless half-step kings who have achieved the title of king has been nearly sublimated by Xia Yulu in this way, and the spiritual torment of this special sharpening method can be imagined.

"Sister Lu. ”

Tang Long hugged Xia Yulu into his arms vigorously.

"Little villain, everyone is watching. Xia Yulu felt the fiery affection in Tang Long's heart, and her heart was sweet.

"it, you're mine!"

Tang Long kissed Xia Yulu domineeringly.

The embarrassed Xia Yulu pushed Tang Long away and took the lead in entering the underground cave.

Tang Long also followed.

Only Bi Hongming and Zhang Shaopin were left looking at each other.

"Make no mistake, we were so scared that we ran away, and people were there to make out. Bi Hongming said depressedly.

Zhang Shaopin smiled bitterly: "This is the gap." ”

The two sighed outside.

Tang Long and the others, who passed through the entrance of the cave, landed more than ten meters below the surface.

This is a very vast area, and there is no end in sight as far as the eye can see, but this huge place is full of corpses, most of which are human bones, and only a small part are the bones of demon beasts.

Densely packed, except for the bone, it is still bone.

In some places, the bones are piled up and close to the surface, so a slight crack in the surface may reveal the bones in some places.

The unique power that affects the heart of martial arts here is also dozens of times stronger than at the entrance.

It didn't have much impact on Tang Long and Xia Yulu.

The two of them still held hands very cautiously, and flew up, not touching the bones.

Based on Tang Long's understanding, just the power of this kind of entrance that affects the heart of the martial arts is estimated to be not something that those demon spirit clansmen can approach, and it is understandable that they are all afraid to block this place.

Even if it was the remnant master of the Four Great Clans, there were not necessarily a few people who could break in and act, so it was normal that no one would unlock the secrets here.

Tang Long and the two of them found a direction and flew over.

The further you go, the more the ground sinks, and the farther it gets from the surface.

As they went deeper, they reached a place hundreds of meters above the surface.

After reaching more than 5,000 meters, Xia Yulu stopped.

The power that affects the heart of martial arts in this vicinity has been so strong that it can bring a threat to Xia Yulu and it is difficult to bear.

In Xia Yulu's situation, she can't bear it, which basically means that those half-step kings can reach here, which is the limit.

"You're waiting for me here. ”

Tang Long went deep alone.

Tang Long, whose heart of martial arts had been sublimated into the will of the king, still had no feeling.

He can move forward unimpeded.

It's just that as he goes deeper, he gradually finds that the number of bones on the ground is decreasing, but the quality of the bones has changed, the original one has been blown over time, and the wind has turned into femur powder to dissipate, and here there is a pale silver halo, very tough, obviously there have been refining bodies before death, and the bones can be maintained for a long time after death.

About another two thousand meters, at the end of the bend ahead, there was finally a difference.

Scattered bones surrounded the center, and a life gem with a diameter of ten meters and a height of three meters appeared.

It is a very rare gemstone, and it is very surprising that there is such a large piece here.

And above this gem of life lies a sleeping girl in white.

Four huge figures were hovering around them.

In Tang Long's eyes, the four figures were very illusory and unreal, but when he looked at it with the will of the king, he was shocked to find that they were actually the remnant souls of the four titled kings.
