As time passed, the refining of the Heavenly Rank Spirit Grass did not seem to be as smooth as the previous refining of the Earth Rank Spirit Grass.

This Heavenly Rank Spirit Grass was too surging because of the power of the soul, which made the refining speed extremely slow.

It wasn't until a week had passed that the process of refining the Heavenly Rank Spirit Grass had finally come to an end.

Although Chu Yi still had a lot of time because of the time difference inside and outside the Tower of Babel, even so, Chu Yi felt the urgency of time.

Because just now, after finally refining this Heavenly Rank Spirit Grass, Chu Yi heard Ruoruo's voice.

"Master, I can feel that the demons who were chasing us before have discovered us. And it's closer. ”

Hearing Ruoruo's words, Chu Yi's heart immediately tensed, he now had two choices.

One is to continue to absorb and try to break through after refining this Heavenly Rank Spirit Grass. Try to ascend to the heavens before the demon arrives, so that you still have a chance to fight the other party.

The other is to give up the plan to absorb the Heavenly Rank Spirit Grass and leave the Tower of Babel immediately. Escape with David.

However, the first choice is that if you can't break through, even if you can't break through in time, your life will be in danger.

And the second option is that after giving up the absorption, this Heavenly Rank Spirit Grass that has been refined will be emitted in the air in a short period of time, which will waste most of the soul power, causing Chu Yi to no longer be able to use this Heavenly Rank Spirit Grass to try to break through.

After some hesitation, Chu Yi finally chose to continue to absorb.

After all, Chu Yi's heart of pursuing strength will not be shaken.

Moreover, having experienced countless situations that were even more dangerous than now, Chu Yi was absolutely confident that he would definitely be able to break through to the heavens before the demon arrived!

Finally, Chu Yi made a decision and stopped wasting time thinking about it, immediately closed his eyes, and inhaled a drop of refined blood-red liquid that was floating in the air by the soul power in front of him into his mouth.

"Boom!"

In an instant, a violent soul power swept through Chu Yi's whole body in an instant, and it also made Chu Yi's mental method work autonomously in an instant.

He was constantly trying his best to absorb this soul power, and he was running the Heart Law Dragon Divine Technique rapidly, but Chu Yi still underestimated the surging soul power brought by this Heavenly Rank Spirit Grass.

This soul power instantly made Chu Yi's skin begin to turn purple and red, and even the whole person was a little swollen, as if he had begun to feel a little unable to withstand such a surging soul power.

This also made Chu Yi finally understand why there were almost no heaven-level spirit grasses in the mortal world. Because the difference between the heaven-level spirit grass and the earth-level spirit grass is equivalent to the difference between the heaven-level spirit treasure and the earth-level spirit treasure.

The surging soul power contained in this Heavenly Rank Spirit Grass would make Chu Yi, who had even reached the peak of the Heavenly Rank, feel a little unbearable.

But although he felt that this soul power was too violent, and even a little unbearable, Chu Yi was still in ecstasy in his heart in the process of absorbing it.

Because, at least this proves that as long as you can last up and completely absorb the surging soul power from this Heavenly Rank Spirit Grass, then it is completely possible to break through to the strength of the Heavenly Heaven!

As time passed, Chu Yi's body became more and more swollen, even if he was someone who didn't know Chu Yi. I'm afraid that at a glance, I will think that this person is definitely a fat man with a fat brain.

And if someone who knows Chu Yi will be even more shocked, because Chu Yi wants to keep all this soul power in his body at this moment. The face that was already impacted by this violent soul power was distorted, and it was extremely hideous.

Ruoruo, who was watching all this on the side, was a little anxious, and his little hands were clenched tightly. In the end, he pounced on it, and hugged Chu Yi as the soul of the Tower of Babel created by Chu Yi. Ruoruo and Chu Yi can be said to be completely connected.

So when Chu Yi felt that his container was about to explode, another smaller container appeared next to him, and he immediately dragged his soul power towards that container.

Soon. Chu Yi felt a lot better, and because of the diversion, the soul power was not so surging. Ruoruo is not too difficult to support.

And after the soul power in the two of them was entangled together, Chu Yi finally began to absorb this surging soul power with peace of mind......

In the blink of an eye, on the second floor of the Tower of Babel, three months have passed. In this process, Ruo Ruo had already let go of Chu Yi and retreated to the side obediently, because Chu Yi had already absorbed most of the surging soul power from the Heavenly Rank Spirit Grass in his body. Only a small part remains.

Chu Yi always closed his eyes, if he didn't know that Chu Yi was absorbing the power of his soul, outsiders would mistakenly think that Chu Yi was already asleep.

But Chu Yi had a look of ecstasy in his heart at this moment.

Because Chu Yi had already felt that he had touched that layer of restraint. Chu Yi knew that this was the shackles of wanting to break through to the heavens!

As long as he can break through this layer of shackles, Chu Yi will be able to break through to the strength of the primary heaven!

As soon as he thought of this, Chu Yi couldn't help but feel ecstatic and excited in his heart.

You must know that Chu Yi is now memory loss, even if he has broken through this level. But in Chu Yi's memory, there was no impression at all, so. This is equivalent to the first time that Chu Yi has approached the strength of this Heavenly Heaven, and it is extremely close!

Even, among the people in the mortal world that Chu Yi has come into contact with. Chu Yi can be very proud, because he is the first person in this group of people who has the best chance of breaking through to this heaven!

Even, even the emperor who had broken through to the peak of this heavenly rank decades and nearly a hundred years earlier than Chu Yi. It hasn't been done at all!

Finally, another half a month passed, and Chu Yi finally absorbed all the soul power, and he could already clearly feel that the restraint had become extremely clear, as if it was just in front of him.

Chu Yi finally began to try to break through, and after the mental method in his body drove the soul power in his body that became incomparably surging, the soul power in his body was like a long river flowing continuously, and finally converged together, rushing towards this layer of restraint.

"Boom!"

But. This time, the shock ended in absolute failure, because there was not even any fluctuation in this layer of bondage.

Chu Yi didn't believe in evil, and gritted his teeth again and launched an impact.

"Boom!"

"Boom!"

Two shocks in a row. Chu Yi finally frowned.

Because he found that his impact had not even touched this restraint, as if some invisible force was standing in front of him.

However, this doubt did not last long, and Chu Yi quickly understood.

This invisible force is the power of the Great Dao!

This also proves that only a martial artist at the peak of the Heavenly Rank who has mastered the power of the Great Dao has a chance to break through to the strength of the Heavenly One!

Chu Yi breathed a sigh of relief after discovering this, because he was very confident that he had already mastered the power of the Great Dao when he was once at the middle level of the Heavenly Rank!

Since the power of the Great Dao is a vital existence, he will definitely be able to break through this shackle with the power of the Great Dao and reach the realm of the Heavenly One Heaven that he has never reached!

But at this moment, Chu Yi heard Ruoruo's worried voice.

"Master, the demons have come, they have found us!"

When Chu Yi's heart sank, Ruoruo had already waved his hand and projected the scene outside the Tower of Babel in front of Chu Yi.

Chu Yi saw the figure of the demon that had appeared in the sky outside the Tower of Babel, and David who was trembling next to the Tower of Babel.

Seeing this scene, Chu Yi's joyful mood just now completely disappeared, his face was extremely serious, he knew that his time was running out!

Converting the passage of time, from the current location of these demons to their approach, I'm afraid it will only be less than half a minute!

This means that Chu Yi only has less than half an hour!

These demons are obviously decisive existences, if they can't break through to the heavens within half an hour, it means that after killing David, these demons will attack the Tower of Babel, which has already been seriously damaged!

With the current level of defense of the Tower of Babel, it will definitely not be able to withstand the onslaught of these demons!
