Mr. A and Mr. B looked at each other, realizing that since both Nascent Soul cultivators had spoken, it must not have been their fault.

Qi Zhiheng called Mr. Yi out and said, "This mushroom is probably a breeding ground for demonic energy. It contains a trace of demonic energy. You just used your soul power to investigate, and it seems that it has already been contaminated."

Mr. B said, "But senior, I don't see any signs of demonic energy on myself."

"Don't resist, let me take a look." Qi Zhiheng probed Mr. Yi's body with his soul power and finally saw a wisp of demonic energy swirling in a corner of his sea of ​​consciousness.

After his soul power withdrew, he said to Mr. Yi, "The demonic energy has taken root in your sea of ​​consciousness."

Mr. Yi was startled and immediately knelt down, saying, "Please, Master Qi, save me!"

Qi Zhiheng had already tried once and shook his head, saying, "My skills are not enough to save you. However, I will report your situation to the sect leader when we get back, and the sect leader will find a way to help you treat it."

Mr. Yi, noticing something in Qi Zhiheng's words—that he used "you all" instead of "you"—brought courage into his mind and asked, "Could there be others like me?"

Qi Zhiheng said, "There are others like you who, after some time, may organize those infected with demonic energy and head to Wuchen Temple."

Mr. B heard the name of Wuchen Temple and his heart, which had been in his throat, calmed down a bit.

Qi Zhiheng examined Erbao again and confirmed that he had not been tainted by demonic energy. As for the other children, he did not examine them. Children are still fragile, and if they had any resistance to him, it would make the examination difficult and might even hurt them.

Erbao faced the black mushroom twice at the Ruins. If he were to get infected, Erbao would be the first to be infected. Since Erbao is fine, then the others should be fine too.

As for the black mushroom, he had come into close contact with it. Unless one directly touches it with soul power or spiritual power, it is unlikely to contaminate one's ears or body.

Mr. A asked, "Master Qi, what about the black smoke emanating from those mushrooms of Compassion? Could this demonic energy have gone somewhere else?"

Qi Zhiheng shook his head and said, "No, those skeletons made of black smoke were just residual demonic energy, which should have dissipated by now."

"But we haven't done anything yet, how did the demonic energy dissipate?" Mr. B had also urinated on the mushroom before, and there was no reaction at the time.

Qi Zhiheng looked at the children who had regained their liveliness and were chattering away, with a strange expression: "Actually, the reason is quite simple. The urine of young boys is the nemesis of magical monsters."

Mr. B suddenly realized! These children's urine—wasn't that virgin urine? He then thought of his own previous behavior and felt a pang of shame. No wonder his urine hadn't reacted; it was because he wasn't a virgin…

Qi Zhiheng did not intend to delve into the matter further. He studied the remaining mushrooms and made notes on the experiments, planning to report back to the sect leader upon returning.

Qi Zhiheng came to his senses and considered whether to interrupt the training. In the end, he decided not to alert the enemy and to discuss a countermeasure with the sect leader when he returned.

Qi Zhiheng told the three gentlemen not to reveal this matter, and that he would contact them after reporting to the sect leader. As for the training, let it continue.

Qi Zhiheng erased the part about mushrooms from the children's memories. Children are most likely to bring up things they are interested in unintentionally. If they were to expose this, it would probably alert the Tianyuan Sect. However, if they were to say that the Lushen Sect was cultivating demonic energy in their own territory, then they would really be unable to explain themselves.

Yang Yitian led Qi Zhiheng to a corner and asked, "Shall we continue our training?"

Qi Zhiheng said, "You continue to follow the children. If anything happens to my disciples, please keep an eye on them for me. I will go back and report this matter to the sect leader to discuss how to deal with it."

After erasing the children's memories, Qi Zhiheng and several teachers went into hiding, leaving the children to continue their trials.

After seeing that the children had resumed their normal lives of killing spirit beasts and collecting spirit herbs the next day, Qi Zhiheng returned to the Slaughtering God Sect alone.

%;

Unlike his leisurely arrival, he was in a hurry to return. What should have been a three-day journey, he arrived at the sect in a single day.

The first thing I did upon returning to the sect was to go to Lufeng to see the sect leader.

Upon hearing the report from his subordinates, Que Hanhai asked with some curiosity, "Qi Zhiheng? Didn't he take his disciples on a training expedition?"

Qi Zhiheng made quite a commotion when he left, and Que Hanhai heard about it. His return at this time was indeed a bit suspicious. Que Hanhai said, "Let him in."

Qi Zhiheng entered the main hall, bowed, and said, "Greetings, Sect Master."

"No need for formalities. What brings you here today?" Que Hanhai asked, inviting someone to sit down so they could begin their conversation.

Qi Zhiheng didn't beat around the bush and went straight to the point: "When I traveled at this time, I discovered something not so good."

"Didn't you go to the Thousand Water Mountains? What could you have found there? Is the spiritual vein about to dry up?" Que Hanhai didn't seem to care much about what he was talking about. If it wasn't urgent, it didn't matter to him right now.

Qi Zhiheng sighed and recounted how Erbao discovered the black mushroom and how he discovered it contained demonic energy.

Although Que Hanhai knew the situation was somewhat bad, he couldn't help but burst into laughter upon hearing Qi Zhiheng's description: "What a fine puddle of boy's urine! Your son has really done a great job this time."

Qi Qingheng said helplessly, "Sect Master, let's talk about meritorious service later. Right now, our sect's situation is not good."

Qi Zhiheng then listed the findings of his investigation and told Que Hanhai about them.

First, this mushroom will not be contaminated by demonic energy if touched directly, but it will be contaminated by demonic energy if touched through spiritual power or soul power.

Second, directly chopping or crushing these mushroom chains is useless. After these black mushrooms are picked or crushed, new mushrooms will grow next to them.

Third, as time goes by, new mushrooms will sprout from these mushrooms, which shows that these mushrooms can grow continuously.

I've come up with a solution for now: watering the mushrooms with boys' urine will completely destroy them.

Qi Zhiheng said, "Sect Master, I will temporarily call these mushrooms Demonic Qi Mushrooms. I have found more than one place in the Thousand Water Mountains. With so many Demonic Qi Mushrooms in our Lu Shen Sect's territory, there is a possibility that more fellow disciples will be infected. Therefore, I think it is imperative to destroy the Demonic Qi Mushrooms to prevent more and more disciples from being infected in the future."

Que Hanhai said, "The timing is rather ingenious. I'm afraid these things are inextricably linked to the Tianyuan Sect, but unfortunately we have no evidence." Since such a situation has occurred in the territory of the Lushen Sect, I'm afraid the territories of other sects are not necessarily peaceful either.

Qi Zhiheng was thinking about many things. If there were demonic mushrooms in the Thousand Water Mountains, would there be any in other training locations? If such a situation occurred on a large scale, wouldn't the Southern Continent be in for a great calamity?

"Currently, we have no evidence to suggest that these things are related to the Tianyuan Sect. I'm afraid the more we tell them, the less likely they are to admit it." Que Hanhai frowned. This situation was somewhat unexpected. He had originally thought that one could only be infected by contact with people from the Tianyuan Sect. Now that Qi Zhiheng had brought back this news, it was clear that one did not need to be in contact with people from the Tianyuan Sect to be infected. Wasn't that worrying?

Qi Zhiheng said, "To find a solution, we first need to figure out how to locate the Demonic Mushroom."

Therefore, he came up with some more plans.

First, we need to refine a batch of spiritual artifacts that can find the Demonic Mushrooms. The aura of the Demonic Mushrooms is extremely weak, and there are no spiritual artifacts available. Searching for them in such a vast area is extremely difficult. Even if we send out everyone in the sect to search, we may not be able to find all the Demonic Mushrooms. If we cannot eradicate the Demonic Mushrooms, they will come back with a vengeance.

Secondly, there must be a team of cultivators specifically tasked with finding the Demonic Mushrooms. This makes it most suitable for disciples infected with demonic energy to go to the Xun Residence. Ideally, someone in the team should still be a virgin.

Qi Zhiheng also gave Que Hanhai a suggestion: to find someone to buy children's urine from the children in the academy!

Que Hanhai's lips twitched. He reserved his opinion on Qi Zhiheng's suggestion to buy urine from children. He couldn't think of any reason to buy urine from these children, since the matter of the Demonic Mushrooms couldn't be revealed to outsiders yet.

"Let's not rush into buying the boy's urine. Let's have someone make a magical artifact that can locate the demonic energy seedlings first, and confirm the distribution range and quantity of the demonic energy mushrooms before deciding whether to buy the boy's urine from the children." Que Hanhai thought to himself, if the distribution range of the demonic energy mushrooms is not large and the quantity is not many, then there is no need to buy the boy's urine.

Qi Zhiheng didn't try to persuade him much, and took out the few demonic mushrooms he had collected.

These few Demon Mushrooms are still growing on the ground, because as soon as he picks them, they lose their effect, and new Demon Mushrooms will grow on the ground. He has no choice but to bring the soil back with them.

Qi Zhiheng frowned slightly. Two more of the demonic mushrooms he had brought back had grown, which was quite fast.

With these samples, studying magical artifacts becomes much simpler.

Que Hanhai was very satisfied with what he brought back and planned to find someone to forge a magical artifact for searching for demonic mushrooms on a large scale.

After Qi Zhiheng finished explaining everything, he took his leave, saying, "Sect Master, my disciples are still waiting for me. I must return to the Thousand Water Mountains."

Que Hanhai didn't stop him, and waved his hand, saying, "Go back and keep an eye on the situation over there."

After leaving Lufeng, Qi Zhiheng headed back towards the Thousand Water Mountains. It took him a day to return to the Thousand Water Mountains and find Yang Yitian.
