The few people outside the formation didn't dare to be careless as they watched the black masses of demonic insects charge towards the human camp. Although these demonic insects were only in the initial stage, there were simply too many of them.

The formations outside the camp were being devoured bit by bit by the demonic insects. Although the killing formations strangled countless demonic insects, the demonic insects seemed to be endless as they continued to attack the formations without any care for their lives.

"Master Shui, someone was poisoned!" Jia Yuan said to Shui Yunzi as he watched the number of Fasting stage martial artists turning hostile.

"There's no need to look anymore, this Water Immortal Ancestor has some methods. If he can withstand the power of the natural laws and lay down such a formation, the Eternal Demon Insects are no longer able to break through. The human camp has been poisoned by the Feng poison, and even if they don't have the Eternal Demon Insects, it would be more than enough for them to deal with it. Let's go back first!" After saying that, he directly walked toward the demon side. The four demon children nodded with a smile and followed him back.

Seeing the demons leave, Ao Feng and the others let out a sigh of relief, directly entering the array formation. However, when they returned to the human camp, the scene in front of them caused their faces to darken.

"Li Yao, Jia Yuan, the two of you, stay by old man Shui's side. Don't let anyone touch the old man." Shui Yunzi released his nascent soul, and then integrated his consciousness into the great formation. Naturally, his current body could not endure much longer.

Then, Ao Feng gathered a group of human experts together. The Poison Demon had just appeared, and there were already close to a million martial artists that were poisoned. Once Guo Xie left, it would become a big problem for the people in front of them to deal with the poison.

"Let those kids in the infirmary try it out. After staying with Guo Jiu for so long, he might have some ideas. In the field of pharmacology, those kids are much stronger than me. If I need anything else, I'll come find you." Qin Feng said in a light voice, and everyone nodded their heads.

Following that, the entire infirmary became busy. Yu Er also came out from Everlasting Palace and used mortal medicine to detoxify the poison in the world. It was understandable. Some tasks could only be done by the students in the infirmary.

"Armor Emperor, that medicine didn't work. Let's do it again!" Yu'er spoke softly to the armored man, who nodded.

"Qiankun, what are you doing?! Quickly put that thing down!" Yu'er watched as Cao Qiuqian pierced a few needles into a cultivator's body, and then stabbed the needles into her own body.

"Big Sister, if you want to find a solution to this poison in a short period of time, we need someone to test the poison on us. Only then will we have a chance to find a way to cure it." Cao Qiuqian said softly.

"No, you can't. They're martial arts cultivators, so they can guarantee their survival right now. If you try the poison and can't get the antidote within three days, and Guo Tai can't come back, you'll definitely die!" Yu'er said softly.

"Big Sister, didn't Master Li Shixin say that just now? If Boss is unable to reach within three days, and if Water Lord's array is unable to stop those fellows outside, then we will all be in danger. If that's the case, I will test the poison myself and wait for Boss to come up with the antidote. If Boss can come up with the antidote, then everyone can be saved. After Cao Qiuqian finished saying those words, the silver needle in his hand pierced into his arm. After a moment, Cao Qiuqian's face turned black, a frightening black.

"Yellow, brown bean, musk, blue juice, big and small bean juice, bamboo juice, hemp juice, six animals' blood, white tooth crumbs, root crumbs, earthworm crumbs, lotus root, water chestnut juice, small and small, hurry and prepare!" Jia Xiaoxiao did not dare to delay, and He Mo and the other girls also went to prepare. After about ten minutes, Cao Qiankun had already fallen into a coma, but there were seven to eight prescriptions written on a piece of paper.

"Let's follow these prescriptions and give it to Qiankun. If Qiankun is unable to withstand it, I will test the poison myself until I find the antidote!" A few of the girls began to cry as well.

"Guo Xie will be proud of you! Give each of them one pill and mix it according to the recipe Su Tu left for the martial cultivators to use. Don't worry about the poison, using poison against them should be able to cure the poison in their bodies. " Although Yu Er looked a little better after taking the last medicinal formula and pill from Su Tu, but because her body couldn't hold on any longer, Su Tu said softly.

After the seven people tried the poison, they found a way to temporarily control it. A group of martial arts cultivators, who had more or less recovered their consciousness after taking the Chinese medicine, looked at the group of doctors who had collapsed and were filled with gratitude.

"If Guo Xie doesn't come back today, then we'll have to be ready to fight to the death with the Demon race." Yu'er looked up at the starry sky and said softly.

"Yu'er, if Shui Yunzi's formation disappears, don't panic. The demons want to kill the human cultivators. Let's get through this first." One of the nine mighty Celestial Kings stood up and said softly.

"Brother, we don't like hearing your words. Since it's a human matter, even if we die, we will drag a few of the devil race down with us!" A human rogue cultivator shouted, and many people around him nodded their heads. The poison had been dealt with, and looking at this group of doctors, what was there to be afraid of? At this moment, the human cultivators were all in high spirits.

"Divine Emperor Cauldron, it's been tens of thousands of years since we last met. Come with me!" Guo Tai tore open a space, and a golden cauldron over a meter tall appeared in front of him.

"Honorable Divine Emperor, you've finally come!" The cauldron transformed into a human form, a two meter tall burly man said to Guo Xie with a smile on his face.

"Amitabha, I never thought that the Divine Emperor Cauldron would be hidden so deeply. No wonder I couldn't find it after searching so many places." Just as Guo Huai appeared with the Medicine Sovereign Cauldron, the ancient lance that was ignited in the flame of the lamp appeared in front of the two of them.

"Demon Lord, you must be scared after seeing me find the Divine Emperor Cauldron, right?" Guo Que narrowed his eyes as he looked at the burning lamp, "Is the Demon Lord planning to leave the two of us behind in this chaotic space?"

"Haha, Demon Lord, you've lost again. Did you not think that you would appear because of your guilt? In your heart, you already know that you won't be able to win this time, right?" Guo Sou said as he looked at the burning lamp.

"I'm not going to argue with you about this. Divine Emperor Cauldron, you should just obediently stay here. If the Divine Emperor can defeat me this time, then he will naturally come and save you!" Finishing his sentence, a powerful aura enveloped Guo Que and the Divine Emperor Cauldron, and the human form of the Divine Emperor Cauldron disappeared.

"Divine Emperor Furnace, don't worry. I will definitely come and save you within 10,000 years!" Guo Tai said harshly. His figure flashed, and he appeared out of thin air. The Medicine Sovereign Cauldron's plan had failed.
