Listening to the words of the tower guard, Zhuang Yichen's thoughts immediately became clear.

According to the understanding of the tower keepers, this universe, or a broader level than the universe, is divided into three parts! The tower keepers on the highest layer dare not say, and the next is the Void Domain and the Mortal Domain!

In the Void Domain, there are strong people above the True Saint, and characters like Taishang in the Zero Realm may only be regarded as ordinary powerhouses when they reach the Void Domain!

And below the Void Domain is the Mortal Domain! In the Mortal Domain, the Ice Realm and the former Zero Realm, as well as the original world of the Demon Race, should all be regarded as a big world in the Mortal Domain, with the True Saint and the strong above the True Saint.

As for the small worlds within the Evil Realm Source Realm, the level is even lower, and the world origin of these small worlds is basically used for the promotion of the Holy Realm powerhouses!

The only difference is that the evil realm is formed by a trace of evil qi from a great supernatural person.

However, it seems that obtaining the origin of the small world and completely controlling the power of this small world are not equated, and he is not clear for the time being.

"You once said that even a true saint powerhouse like a martial saint in the fifth layer of the Holy Demon Tower has to stop, does that mean that you need a strong person at the peak of the True Saint or even above the True Saint to be qualified to enter! and the breakthrough realm of the fourth layer of the Holy Demon Tower requires the True Saint level!" Zhuang Yichen suddenly figured it out at this time, and asked the tower guard.

"You're right, that's it!" the tower keeper's voice carried a hint of surprise, and it was obvious that Zhuang Yichen's reaction was much faster than he expected.

"A realm that is stronger than the True Saint, then I'm afraid it's the powerhouses of the Dragon King and the Qinglian Sword God!No, maybe they are the people standing at the peak of that level!" Zhuang Yichen suddenly recalled the time when the Qinglian Sword God took the head of a giant in the Eastern Regions with just one ancient sword, such a terrifying strength is simply indescribable!

"By the way, the strength of the peach-eating girl is at least above the True Saint, but is the True Saint really a great supernatural power? Zhuang Yichen asked this question again with some curiosity.

The tower keeper didn't answer, and gave Zhuang Yichen an answer with silence!

"Can't even be sure about this?" Zhuang Yichen said a little speechlessly.

"When you reach the realm of the true saint, you will naturally understand what the realm above the true saint is!

"A great supernatural is naturally a prodigy invincible. The tower keeper replied.

"Then what realm did you once have?" Zhuang Yichen was a little curious! How could there be such an existence as the tower keeper and Xuan Qing in the Holy Demon Tower, and how did they enter the Holy Demon Tower?

"All I can tell you is that I have been at the highest level!" the tower keeper said in silence for a while, finally quietly.

Zhuang Yichen was in awe, for him, the current True Saint realm is unattainable, and the commanding heights of the mortal realm are not counted! Even if this tower keeper is an ordinary powerhouse at the highest level, it is terrifying to Zhuang Yichen.

"Now that you understand the horror of the Void, are you sure you still want to go?" asked the tower keeper solemnly. In the Void Domain, the powerhouses above the True Saint are not as rare as the Ice Realm and the Divine Dragon Continent, and I am afraid that only one can be produced in thousands of years!

As for the True Saint Ya Saint, there are even more of them, even if Zhuang Yichen achieves the Ya Saint realm, it is not a big deal to reach the Void Domain, at most it is only a level that can protect himself.

And don't look at Zhuang Yichen who is now a peerless Tianjiao in the Shenlong Continent, but in the Void Domain, compared to the Tianjiao Holy Son of many powerful races, it is nothing at all!

"Naturally, I'm going!After I have achieved the sub-saint realm and calmed down the threat of the ice realm, I will go!" Zhuang Yichen said lightly. For the first time after stepping into the martial arts, he wanted to go to a higher level so strongly, even if he encountered a strong enemy, he was fearless to fight to the death.

"Very good, courage is commendable!, but even if you become a sub-saint, it is best to fuse the Holy Emperor Ding before stepping foot in the Void Domain!" said the tower keeper very solemnly.

"Could it be that after arriving in the Void Domain, neither you nor the Holy Demon Tower can help me?" Zhuang Yichen thought of this possibility!

"Yes, there are too many strong people in the Void Domain, with my current state and that of the Holy Demon Tower, if someone discovers it, it will inevitably lead to a catastrophe!" the tower keeper said lightly, Zhuang Yichen could hear that what he said was absolutely true.

"In other words, after arriving in the Void Domain, I can only rely on myself completely, which is a bit difficult!" Zhuang Yichen thought that this was a bit of a trick, and when he reached a place at the level of the Void Domain, the strongest arm would be gone!

But at that time, he at least had the strength of the sub-saint level, and he always had to grow up! And in fact, up to now, Zhuang Yichen almost relied on himself more in the later stage, and the tower keepers only made occasional moves! It can be seen that if the Holy Demon Tower is to return to its peak state, there is still a long way to go!

"Not only that, but you'll also have to find a way to find a lot of star cores to restore energy to the Holy Demon Tower!" the tower keeper continued.

"Star core?" Zhuang Yichen couldn't help but ask, this is the first time he's heard of this thing!

"The star core is the core substance of a planet, just like the flesh of a human being!" the tower keeper paused for a moment and then said, "If the origin of the world is the divine soul of a planet, then the star core has an even greater effect on cultivators!"

"I understand!" Zhuang Yichen nodded, after all, he came from the earth, and he still understood the structure of stars and some basic concepts! Matter itself is greater than the soul, and no matter how powerful the soul is, it also needs to be attached to a strong enough substance, which is the known absolute law at present.

"Okay, the most important thing for you right now is to advance to the Sub-Saint Realm, and then settle the matter of the Ice Realm! If the cross-border passage is really completely opened, it will definitely be a tricky matter!" the tower keeper admonished!

He suddenly realized that Zhuang Yichen had actually stood in a position where he could influence the fate of the human race at this time, which had to be said to be a miraculous process.

And this growth process is a bit of a miracle.

"Solve the threat of the ice realm, I will! Everything will take a little time, I know ......" Zhuang Yichen's gaze became extremely deep at this time! Now his strength is actually not inferior to that of an ordinary sub-saint powerhouse, and using all the strength of the human race can also help him find two world origins that are strong enough!

It's just that he faintly felt that something was wrong in his heart, and it seemed that he shouldn't be so hasty in promoting Yasheng, otherwise he would definitely regret it in the future!
