However, Li Yi did not stop cultivating, if he wanted to defeat the Quartet Tianzun and rescue Shi Niang, he still needed to become stronger, and he needed to increase his certainty of victory.

At present, he is only a stone's throw away from breaking through the fifth level of the realm, as long as he refines the natal essence blood of the Blood Poison Heavenly Venerable, he believes that it will be easy to break through the fifth level of the realm.

So after dawn, Li Yi slipped into the Xishan cave again, urged the law of devouring, sucked the natal essence blood of the Blood Poison Tianzun into his body, and then ran the demon refining technique on the one hand, and on the other hand, with the help of the power of the Nine Shadows Gangfeng, he dispersed the natal essence blood of the Blood Poison Tianzun.

In the evening, Li Yi returned to his residence, escaped into the Mirror Demon Realm, and continued this penance with the help of Biying and others.

A day passes, and another day passes......

On this day, Li Yi was cultivating in the Mirror Demon Realm, and when the last trace of Blood Poison Tianzun's natal essence blood was also refined by him, his realm suddenly shook, and a huge transformation occurred in an instant, expanding by eight hundred zhang, and it actually enveloped the space within a radius of two thousand zhang in one fell swoop.

Field fivefold!

Compared to the fourth time, Li Yi's realm has fully doubled, and the realm with a radius of two thousand zhang is enough to be proud of the others, not to mention the same realm, even if it is three or four realms higher than him, the realm may not be as big as him.

You must know that there are four laws in his field, the more laws, the more difficult it is to break through, but once you break through, the greater the improvement.

In a realm of two thousand zhang, the four laws operate at the same time, how powerful will it be, even Li Yi is very curious, and he can't wait to verify it.

"Quartet Heavenly Venerable, your time of death has arrived!" Li Yi said to himself.

He left the Mirror Demon Realm and rushed to the direction of the main hall, he still maintained Chen Banfang's identity and appearance for the time being, and did not return to his original appearance.

Since the second explosion, there were almost no monsters in the area near the main hall, so the monsters patrolling and guarding were also far away from this area, and Li Yi didn't have to make much effort to go deep into it and come to the side of the huge pit.

But next to the pit, there were more than a dozen monsters guarding the town, and when they saw him approaching, they immediately shouted from a distance: "This is not the place for you to come, you half-human and half-demon bastard, get out of here quickly!"

Li Yi snorted coldly, how powerful his current strength was, the law of illusion immediately urged.

The dozen or so monsters were immediately honest, and all of them were controlled by the illusion.

Li Yi was about to fly into the bottom of the deep pit, but at this moment, the earth shook suddenly, and some low rumbling sounds came from the ground.

In the distance, many youkai panicked and shouted loudly.

"The third explosion is coming, everyone get away from the main hall!"

Thinking of the previous two explosions, the second one was more violent than the first, and this third explosion was probably even more violent, Li Yi felt a little solemn in his heart, and before he could think about it, he flew into the pit.

The huge pit was more than 100,000 zhang deep, and when it reached the bottom, Li Yi even saw magma flowing out of the surrounding stone walls, and the temperature became extremely hot.

The earth shook more and more violently, and the rumbling became denser and louder.

Li Yi fell to the deepest depth, stepped on the ground with both feet, and saw that it was like a wide square at the bottom, in the center of the square, there was a refining furnace hundreds of zhang high, and dozens of slightly smaller refining furnaces were distributed around, and each refining furnace was burning with a raging fire, and something seemed to be calcining inside.

Li Yi didn't want to think about it, with a wave of his big sleeves, a strong wind swept out, sweeping all the dozens of refining furnaces to the ground, and suddenly the flames scattered, illuminating the ground even brighter.

I saw that there were thousands of holes around the square, and only one of them was firmly sealed by an iron gate.

Li Yi flew to the front of the iron gate, urged the law of gold, and the iron gate slowly opened.

The law of gold can manipulate metal substances, just like the iron door automatically opened for Li Yi, if it was before, I am afraid that he would have to use violent means to forcibly destroy the iron door before he could enter it.

Inside, there was a dark and deep passage, and there was an even hotter breath from it, as if even the air was about to burn, and at the same time, those rumbling sounds came from the depths of the passage.

Li Yi walked along the passage, he urged the Instant Demon Divine Power and the Wind Demon Divine Power, the speed was extremely fast, but it also took a lot of time before he reached the end, only to see that on both sides of the passage, there were many stone rooms closed by iron doors, and under the crack of the door, there was a faint flickering firelight.

Li Yi urged the law of gold and opened the iron door.

I saw that there was also a refining furnace in the stone room, and there was a scrawny old man sitting next to him, who was manipulating the flames and calcining the contents of the furnace.

The old man's soul and body seemed to have been severely damaged, and he had never heard of Li Yi's intrusion.

"Senior!" Li Yi shouted.

The old man was still indifferent, just staring blankly at the refining furnace.

Li Yi knew that this old man was one of the refiners captured by the Quartet Heavenly Venerable, and looking at his refining techniques, it seemed that he had a lot to do with the Holy Spirit faction. In desperation, Li Yi had no choice but to leave the stone chamber and open the iron doors of the other stone chambers one after another.

Inside each stone room, there is a refiner and a furnace.

Those refiners were also in a very bad state, almost on the verge of death, and they were all sluggish, and when they saw the stone door open, they had no idea of escaping.

Li Yi found Gu Lianzhen in one of the stone rooms.

Because he took the opportunity to escape during the first explosion, Gu Lianzhen's legs were cut off, and he could only kneel on the ground to refine the weapon.

Gu Lian was really tortured, and it seemed that he didn't recognize Li Yi anymore, and he looked like he was demented.

Li Yi was secretly angry in his heart.

The Quartet Heavenly Venerable captured these refiners, it can be said that they were slaves, refining weapons from morning to night every day, barely having the slightest time to rest, and if they slacked off, they would be beaten, which led to a great loss of their souls.

Li Yi was anxious to find his master, and he didn't care about Gu Lianzhen, so he continued to open the remaining stone room.

There are more than 100 stone rooms, there are more than 100 refiners, Li Yi once heard Gu Lianzhen say that these refiners are all refining the same magic weapon, but each person is responsible for a small part of the accessories.

In other words, in the end, those accessories will be assembled and become a complete magic weapon.

Li Yi guessed that the magic weapon was likely to be a legendary immortal weapon.

Only an immortal weapon is worth spending such a huge project.

Finally, in the innermost stone room, Li Yi met his sister Yang Xiaohua.

Yang Xiaohua was also devastated, looking hundreds of years older than Li Yi remembered, and she had lost a lot of weight, leaving only skin and bones, and she was simply tortured to the point that she was not human.

"Master!" Li Yi couldn't help but have a sour nose when he saw Yang Xiaohua's miserable condition, rushed forward, helped Yang Xiaohua up, and sent a strong true qi into Yang Xiaohua's body, and at the same time put away the transformation power and restored his original appearance.

Yang Xiaohua regained a little vitality at this time, and when she recognized Li Yi, she couldn't help but burst into tears and tremble, but she couldn't speak.

Li Yi was furious in his heart, and he couldn't wait to immediately shatter the corpse of the Quartet Heavenly Venerable.

"Master, I'll send you out of here first. Li Yi took out a Xuanjin Mirror and was about to send Yang Xiaohua into the Mirror Demon Realm, but at this moment, deeper underground, a violent explosion suddenly sounded.

Bang!

It's like a thunderbolt from the sky, almost piercing people's ears.

The ground fell apart, all the stone chambers collapsed, and clusters of flames erupted from the ground, almost turning this space into a purgatory.

I saw four figures standing in the midst of the flames.

Among them, the Southern Tianzun stands in the south, and the other three directions are the Western Tianzun, the Northern Tianzun, and the Eastern Tianzun.

The Quartet Heavenly Venerable all lowered their heads and looked at the flames, their faces full of excitement.

"It's successful, it's finally successful!" Southern Tianzun was ecstatic, his voice trembling a little.

"There is still one last step left!" Dongfang Tianzun said in a deep voice, compared to the other three Tianzun, his expression was the most calm, "Quenching is the top priority, and there is no room for the slightest mistake." Only when the quenching is successful, this immortal weapon can be regarded as refined, and at that time, its power can be exerted to the maximum!"

Western Tianzun nodded and said, "Big brother is right, now is the most critical time, fourth, you have to stay calm, don't get too excited!"

However, having said that, Western Tianzun's own breathing was also a little short.

Dongfang Tianzun said: "A little flea came in just now, fourth, you go and take care of him, so as not to make any mess when the immortal weapon is born." ”

It turned out that Dongfang Tianzun had already noticed that Li Yi had come in, but at this time, all his attention was on the immortal weapon under the flames, and he didn't even look at Li Yi.

Nanfang Tianzun turned his head, looked at Li Yi, and said coldly: "I heard you speak just now, it seems that you are her disciple." You are not small, you can actually get here, but if you want to save people, you are still a little tender!"

As he spoke, he jumped up and punched Li Yi.

This punch was extremely powerful, almost tearing through the void, and it arrived in front of Li Yi in the blink of an eye.

Li Yi urged the law of gold, and his physical body was instantly strengthened tenfold, and it was also blasted out with a punch.

Boom!

Nanfang Tianzun was directly shocked and flew away, and one of his arms was even shattered, and his flesh and blood flew sideways.

Although his strength is strong, he is too light on the enemy, thinking that since Li Yi is Yang Xiaohua's disciple, his strength is definitely not good, after all, even Yang Xiaohua was arrested by them, so Nanfang Tianzun did not release the realm, nor did he urge the law.

But he didn't expect that Li Yi was ruthless, and he used the power of the Golden Law with the first punch, plus his physical body was already strong, and his true qi gushed out, where could Nanfang Tianzun withstand it?

Nanfang Tianzun broke an arm, and under the severe pain, he couldn't help but be shocked and angry, and shouted: "Who the hell are you?!"

The other three Heavenly Venerables also showed surprise, they didn't expect that Li Yi's punch might be so powerful.

Li Yi patted the storage bag, released Xiao Qi, and said, "Take care of the master." ”

It takes a certain amount of time to open the Mirror Demon Realm, and now that the Quartet Tianzun is in front of him, Li Yi can only temporarily let Xiao Qi protect Yang Xiaohua, and he will go to solve the Quartet Tianzun first.

He saw that Shi Niang was tortured by the Sifang Tianzun to the point that he was not human, and the hatred in his heart was monstrous, and he didn't talk nonsense with the Southern Tianzun at all, and he punched it again.

Nanfang Tianzun had already put away his contempt, he didn't dare to hold it up, and hurriedly released a domain with a radius of 1,400 zhang, flashed to the side, dodged Li Yi's fist, came behind Li Yi, and shrouded Li Yi in the domain, and at the same time, it was also a punch, blasting into Li Yi's vest.

"What a fast speed!" Li Yi was a little surprised, he didn't even see clearly just now, how Nanfang Tianzun flashed past, but during the battle, he couldn't think too much, and his body shook and released the realm.

His realm has reached a full two thousand zhang, which is six hundred zhang larger than the realm of the Southern Heavenly Venerable.

The Law of Gold was running at full strength, and Li Yi's realm became even more indestructible, and he stubbornly withstood the blow of the Southern Tianzun, but also shook the Southern Tianzun back.

"Domain?" Southern Tianzun's eyes widened, and his expression was even more shocked.

"Who the hell is he, who can actually refine the realm?" The other three Heavenly Venerables were also shocked.

As a human race, just refining the realm is enough, it is still a realm with a radius of two thousand zhang, such a large realm, even the strongest Dongfang Tianzun is dwarfed.

"The third one, you go to help, the fourth one is not his opponent!" Dongfang Tianzun immediately made a decision without the slightest hesitation. With such a big gap in the realm, it was obviously impossible to defeat Li Yi by relying on Southern Tianzun.

Northern Tianzun immediately rushed forward, his body was in mid-air, and he released a field with a radius of 1,500 zhang, and shouted: "Fourth, let's go together!"

As soon as the words fell, the Northern Heavenly Venerable and the Southern Heavenly Venerable flashed at the same time, striking Li Yi from front to back.

Their speed was extremely fast, making it impossible for Li Yi to dodge, even if Li Yi urged the Instant Demon Divine Power and the Wind Demon Divine Power at the same time, he still couldn't dodge.

Seeing the bombardment of the two realms, Li Yi snorted coldly.

The Law of Thunder!

The second law was put into operation, and in Li Yi's realm, in addition to the golden light, there were countless thunderbolts, and the realm became stronger and stronger.

Bang!

The three major realms collided together, Li Yi was stunned, while the Northern Tianzun and the Southern Tianzun were both shocked and flew out, and their domains were not affected a lot.

This is still after they find out that the situation is not good, and retreat in time, otherwise the damage will only be more serious.

"The rule of two?!"

The Quartet Heavenly Venerable was shocked again, it was already terrifying enough to see Li Yi sacrifice a realm with a radius of two thousand zhang, but as soon as these two laws were sacrificed, the shock was even stronger.

Dongfang Tianzun had to re-examine Li Yi again, he didn't understand, why Yang Xiaohua was so weak, and his disciples would be so strong, but the matter had come to this, it was useless to think so much, the top priority was to deal with Li Yi's trouble, otherwise after the immortal weapon was successfully quenched, there might be a big mess.
