In terms of the Yin and Evil Qi found now, Chu Du felt that collecting them was enough for him to successfully fuse the Yin and Evil Qi, but when they were all here, Chu Du wanted to continue to explore and see why there were so many Yin and Evil Qi here, anyway, he had enough top-grade spirit stones on his body, and they could support him for a long time, if he couldn't stand it, he would just quit.

When Chu Du began to feel sorry for his top-grade spirit stone, he found an extremely amazing scene against the Nine Dragons Divine Fire Cover, only to see that a wall of light appeared in front of the flames to disperse the evil qi, like a wall of crystal glass in front of Chu Du, this wall of light exuded incredible energy fluctuations, making Chu Du feel its indestructible might.

Due to the limited amount of Yin Evil Qi dispersed by the flames, and the fact that this place was filled with Yin Evil Qi that was so thick that it was almost liquefied, Chu Du's divine sense could not detect much far, and he couldn't see how big this wall of light was at this moment.

Chu Du first moved sideways along the wall of light, and as a result, he flew for 10 days in a row, and still did not see the edge of this wall of light, but in the process, Chu Du was surprised to find that there were small cracks in some places on this seemingly indestructible wall of light, and these cracks bubbled outwards with a strong yin and evil aura.

At this time, Chu Du understood how the yin and evil qi in this place came from, and he also roughly understood the function of this wall of light. The world behind this wall of light must be a world full of yin and evil qi, if there is no wall of light, all the yin and evil qi in the back world will pour in, then Chu Du dares to say that no matter which continent it is, all of them will have to be finished.

Because Chu Du thought of what the dream demon had said to him before, the Xuanhuang Great World used to have nine continents and six oceans, but now there are only three major places, the Ten Thousand Beasts Continent, the Origin Continent and the Sea of Illusion, and as for the Tianyu Continent, it is simply negligible. The dream demon said that the other continents and oceans have collapsed, and these collapsed places are many times larger than today's territory, and there must have been an extremely large number of creatures living on them back then.

With so many living beings dying, there must be so much yin and evil qi formed that it must be terrifying, so Chu Du thought that it was light

Once the sinister aura behind the wall breaks through the wall of light and enters the current Xuanhuang Great World, then the Xuanhuang Great World will only have the result of complete destruction.

"Could it be that this wall of light was also made by the Heavenly Dao? It seems that he is really heartbroken for the Xuanhuang Great World! It is really too hard to prevent the Yin Evil Qi from eroding into the only remaining living beings to live, and at the same time to prevent those monks from soaring and taking away more energy to cause the Xuanhuang Great World to continue to collapse!" Chu Du couldn't help but sigh when he thought of these things, and expressed deep sympathy for the Heavenly Dao.

"This wall of light must have completely surrounded the current Xuanhuang Great World, it is really an incredible project, how did this be done, is this also a super large formation?" Chu Du sighed after flying along the wall of light for a while, and then he changed his direction and rushed upwards with all his might, he wanted to try to rush to the extremely high air to see if there was any yin qi on it, if not, he could see the whole picture of the Xuanhuang Great World at a glance, and see if the Xuanhuang Great World was really surrounded by the wall of light.

Chu Du flew all the way upwards like this, he didn't remember how many top-grade spirit stones he had consumed, and finally came to the high sky without yin and evil qi, in front of him, the wall of light was still standing, as if it was simply connected to the canopy.

At this moment, Chu Du didn't know what the distance between himself and the ground was, he only knew that as soon as he turned around, he could see the brilliant purple light in the extreme distance, which was the light emitted by the Void Cloud above the Sea of Illusion! What surprised Chu Du was that such a purple light actually formed a huge circle, enclosing the Ten Thousand Beasts Continent and the Origin Continent in the middle, that is to say, these two continents were completely surrounded by the Sea of Illusion, and he didn't know if there was a place similar to the Tianyu Continent behind the Sea of Illusion on the Origin Continent.

And Chu Du also saw the wall of light connected to the canopy on the other side, proving that his previous conjecture was correct, the current Xuanhuang Great World is indeed surrounded and protected by these walls of light, but these walls of light have begun to crack in some places, and I don't know how long they can last.

Chu Du didn't know how to repair those cracks on the light wall, and after observing in the air for a while, he didn't go back the way he came, but flew directly from the extremely high sky to the top of the Tianyu Continent, and then returned to the Giant Sun Sect.

After such a long time, Cao Meng and the others were already ready, just waiting for Chu Du to take them across the Sea of Void, Chu Du naturally started to set off immediately, because collecting Yin Qi required some special containers, he was ready to hurry back and let the Divine Machine Building help build a large batch, and then come back to collect Yin Qi .

Chu Du condensed the Star God Giant and completely used it as a means of transportation, Cao Meng, Ye Qing and the others all rode on the Star God and rushed all the way to Vermilion Bird City.

When passing by the Sea of Illusion, Chu Du came to the City that never sleeps, Chen Yang and Bai Feng were hiding and did not come out to see Chu Du, Chu Du didn't bother to pay attention to them, he directly found Chen Heng, and told him that the monks on the Tianyu Continent would cross the Sea of Illusion in the future, and let him tell the Xia Shui Clan not to do anything to those people.

"I can promise you this, I have never killed those low-level monks, they can avoid the mirage and other water tribes, it is their ability, now I can order the water tribe not to attack your people, but I don't care about the mirage problem. Chen Heng thought for a while and said.

Chu Du felt that Chen Heng's words were a little strange, so he asked: "So you just killed the monk who crossed the sea with a high cultivation? What is the reason for this?" Chu Du didn't think that Chen Heng felt that the monk with a high cultivation crossed the sea to provoke him, so he didn't let any of them go.

"Actually, this is related to a promise of my clan, it is said that my ancestor competed with a master, and after defeat, he promised that person to stay here, and found that the monks who crossed the sea above level 6 were killed, and I actually just followed the ancestral teachings for so many years. Chen Heng said directly.

"I see, I said that the sea of vanity is so big, but your people are staying here. Chu Du suddenly realized, he remembered that there were some cracked walls of light on the side of the Tianyu Continent, could it be that Tiandao deliberately asked the Chen Heng clan to stop those cultivators with high cultivation from passing over to prevent them from causing more damage to those walls of light?

"For this reason, and the Sea of Void near the Origin Continent is not very safe for us to stay, you also know that the monks on the Origin Continent have a lot of benefits, and our clan is much safer away from them, so after our ancestor was defeated, he naturally agreed to that person's request. Chen Heng thought for a while and replied.
