Chapter 2219 Refining the Heart Stone

The edge of the stone wall.

Emperor Chengyuan gently placed his palm on the Heart-piercing Heaven Lock, and held on for a moment before retreating with a pale face.

"It hurts too much."

"This piercing feeling is just like being chopped by thousands of swords, and no secret technique can reduce the pain, and it can only be recovered slowly over time."

Emperor Chengyuan trembled and slowly walked back to the Xingyu Chenguang Tower.

In the tower, Gu Xiuyun and Emperor Xuzhen sat cross-legged and were quietly recovering.

Seeing Emperor Chengyuan come in, Gu Xiuyun opened his eyes and stepped out of the pagoda space.

According to the meaning of Emperor Shi Tian Zuhuang, the three of them could not all stay in the tower, otherwise the consumption of Xingyu Chenguang Tower would be too great, so only two people could stay in the tower to rest at any time, and one person had to touch the Heart-piercing Heaven Lock until they got used to the piercing pain that penetrated their hearts and minds.

The edge of the Heaven Lock.

Gu Xiuyun stretched out his palm.

Huh!

The terrible mental impact surged into the body like a tide, reaching the deepest part of the soul.

However, as soon as the impact force touched Gu Xiuyun's mind, it shattered directly. His mind was too strong, much stronger than any Qiankun Emperor.

Perhaps in terms of quantity, Gu Xiuyun can only be compared with Jiujue Emperor.

But in terms of quality, his mind has surpassed any Qiankun Emperor. After countless years of practice, the Dao Heart Technique has already reached an incredible level. It is extremely difficult to hurt Gu Xiuyun's mind.

"This heavenly chain is really magical."

Gu Xiuyun carefully felt the impact of the power from the depths of the chain.

"The longer the time, the stronger the power and the more terrible the power. If the chain is touched all the time, even Qiankun Emperor will be crushed and become a walking corpse."

"But this power is far from enough for me."

"My mental power should be similar to Jiujue Emperor, but in terms of quality, there is a world of difference."

For a normal Qiankun Emperor, the mental power is like a piece of tofu.

After countless tempering and transformation, Gu Xiuyun's mind has become like steel. Maybe the two are almost the same in quantity, but in terms of hardness, they are completely different.

"The time is too short."

"If I can touch this sky lock for a longer time, such as a few days, a few months or even a few years, I may get a lot of benefits."

"Unfortunately, the old ghost Tianshi has been staring there, and I can't do anything."

Gu Xiuyun pretended to support for a moment, then tremblingly walked towards the silver pagoda.

After a while, Xuzhen Divine Emperor came out. His face was very pale, and it was obvious that he had not recovered enough in the tower.

"Gu Daoyou, how are you?" Xuzhen Divine Emperor did not rush to touch the sky lock.

"Not bad."

Gu Xiuyun shook his head slightly, "I can only hold on for one stick of incense now. If it's longer, my mind will feel like it's collapsing. I don't know how many times I have to try to reach one hour."

"You've already held on for one stick of incense!" Xuzhen Divine Emperor was a little envious, "I still need two hundred and forty breaths to reach one stick of incense, and I have to walk on the chain for an hour and a half. At this rate, it may take tens of thousands of years to reach it."

"Keep trying!"

Gu Xiuyun trembled and walked into the silver pagoda.

The tower always maintained a flow rate of ten thousand times. The amazing flow rate also made his mind slowly recover. Of course, this was just Gu Xiuyun's pretending. It was only one stick of incense, which meant nothing to him.

At the same time, Gu Xiuyun began to refine the heart stone silently.

With the help of the Xingyu Chenguang Tower, it was much easier to refine the heart stone. In thousands of years, he had spent 20 million years in the Xingyu Chenguang Tower. The long time made the heart stone decompose continuously, and one tenth of it had turned into mist.

"Old Sky Devourer, wait until I completely decompose the Hole Heart Stone and integrate it into my natal divine sword..."

"By then, combined with the fusion of the real body, I will have a much better chance of dealing with you."

"But before that, I still have to deduce the secret method of the one sword three disasters to be stronger. In addition, I have to try my best to comprehend the fifth-grade killing rules. From the entry level to the initial stage, there is also a big gap."

Gu Xiuyun was looking forward to it secretly.

Now the other party is in the open, and he is in the dark. The Sky Devourer Ancestor Emperor would never have thought that a Fate Emperor of the Fifth Absolute Realm actually hides a trump card comparable to the Six Absolute Divine Emperor. Although this trump card is far from enough now, as time goes by, Gu Xiuyun's strength is also constantly increasing.

...

Mixed Source Heart Realm, Mind Space.

The Fate Clone and the Killing Clone tried their best to deduce the one sword three disasters secret method.

After the Killing True Body comprehended the fifth-grade entry rules, the power of the Thousand Thoughts Aurora had a qualitative leap. In just a few thousand years, it increased from ten times to twenty-three times.

From this, we can also see how much influence the killing rules have on the secret art.

For a bucket, we should not only look at the longest board, but also the shortest board.

The killing rule is Gu Xiuyun's shortcoming, and it is the most important shortcoming, because in terms of killing power, no system can compare with the killing way.

The combination of fate and killing should be based on killing, and fate should be supplemented.

It's just that Gu Xiuyun's perception of fate is too deep, but he is pitifully weak in killing, so his previous secret art direction is all based on the rules of fate, but it is obvious that this combination method can't play the advantages of the fusion of the true body.

"Thousand Thoughts Aurora, after all, fell behind."

"Killing and fate should be based on the Way of Killing and the Way of Fate as the foundation, so that they can truly exert the power of destroying the world."

"Senior sister is right, I should take the route of one sword and three disasters."

The two clones carefully observed the rules and secrets evolved in the mind space and deduced silently.

Compared with the Three Tribulations Sword of the Azure Sky, the secret method he wanted to deduce was much more complicated, because it not only had to combine the five major rules of the Way of Killing, but also had to integrate the seven rules of the fate system, a total of twelve rules, so that this secret technique had a power far beyond any secret technique in the world from the moment it was born.

...

Time passed slowly.

Gu Xiuyun pretended to follow Xu Zhen and Cheng Yuan every day to endure the heart-piercing stone chains.

The two people's support time was also constantly extended.

In the 9400th year, Cheng Yuan Shen Huang finally reached half an hour.

Then it was Gu Xiuyun. In the 2300th year, he claimed to the outside world that he had reached an hour, but he did not stop trying. To this, Tian Shi Zu Huang did not care.

After all, the Heaven Devouring Ancestor Emperor had said before that the stronger the mind is, the more beneficial it is for cultivation.

As the Five Absolutes Emperor, Gu Daoren certainly hopes that he can go further, and it is also human nature to continue to sharpen his mind with the Heart-piercing Sky Lock.

The Heaven Devouring Ancestor Emperor did not know that Gu Xiuyun just wanted to use this name to continue to stay in the Xingyu Chenguang Tower. Every day, he was desperately refining the Hole Heart Stone, and his mind and will were like a mighty tide, hitting the strange stone again and again.

Until the 37,000th year.

Puff!

The last grain of sand in the stone bead completely decomposed, and the golden mist steamed and surged in Gu Xiuyun's body, like a dark cloud.

"Finally succeeded!"

"In 37,000 years, I have been in the Xingyu Chenguang Tower for nearly 20,000 years. With a flow rate of 10,000 times, I finally decomposed this hole heart stone into mist."

"Next, it is to integrate it into the natal sword."

Gu Xiuyun looked at the body of the killing true body with expectation. There was a blood-colored long sword there. The sword body was light and thin, and it faintly exuded a bloodthirsty taste.

Huh!

As the thought flashed.

The golden mist turned into a dragon and flew towards the sword body.
