The theory of blocking the spring.

Chi Qingshuai didn't say anything, obviously he agreed with my speculation.

"But this doesn't make sense, does it?" Jietou frowned and said, "According to what you guys are saying, King Wu of Wu has been crossing the tribulation all along, and the thunder pool electric array on the mountaintop is meant to kill him. If that's really the case, then King Wu of Wu couldn't have left Mount Modu at all. Once he comes out, he will definitely be killed by lightning. And if it's not him who came out, other small ghosts and spirits wouldn't stand a chance against Mo Ye Sword."

"You asked a good question," I smiled at him and said: "So the person who attacked Chi family was not King Wu of Wu himself but also not some small ghosts or spirits; it was mountain demons and water monsters."

"Mountain demons and water monsters?" Jietou became even more confused.

"Just like you just said," I continued looking at Jietou: "King Wu of Wu has been crossing his tribulation all along so he absolutely dare not come out from Mount Modu because that would basically mean seeking death. Of course, eventually he will come out but that's another story because when he does come out his power will have accumulated enough to overcome any kind of calamity including thunder tribulations or end-of-the-world disasters."

"However before that happens if he wants to deal with people outside Mount Modu it becomes quite troublesome for him. Of course as you mentioned earlier he can send some small ghosts or spirits to deal with them but those little ones clearly aren't strong enough to handle someone like Master Chi whose cultivation level is high." At this point I looked at Jietou again continuing: "You might say that King Wu underlings also include some powerful yin creatures which your guess isn't wrong about either. But it's obvious that those powerful yin creatures are also in the process of crossing their tribulation. So once those yin creatures really come out, they will only have one end which is to be struck by lightning and die."

"In other words, although King Wu of Wu is very powerful and has many soldiers under his command, he can't do anything to Master Chi at all because his power cannot be exerted. Right? What he can send out are just some small fries?" Jietou suddenly realized what was going on and looked at me and Chi Qingshuai.

"Yes, that's right," I nodded my head then looked up at Chi Qingshuai: "Master Chi, I suddenly remembered something."

"What thing?" asked Chi Qingshuai.

"The thunder pool electric array on top of Mount Modu is huge," I frowned: "This shows that there must be more than just King Wu of Wu who's crossing the tribulation inside Mount Modu. Their thunder mixed together to form this huge thunder pool electric array. How did you distinguish King Wu of Wu's tribulation thunder from this massive electric array?

Upon hearing my words, Chi Qingshuai chuckled and said, "There is nothing difficult in the world as long as you put your heart into it. Do you think I've been playing around under Mount Modu for forty to fifty years? If you don't believe me, just look back at the mountaintop. The thunderstorm we see now is the Five Thunder Heavenly Tribulation Formation unique to King Wu of Wu State, which is completely different from other electric formations. Let me tell you this: when this electric formation first appeared, it was generally very mixed up. However, if you observe carefully, you will find a purple lightning in the middle of it all - that's King Wu's tribulation-crossing lightning bolt. The purple lightning appears most frequently and lasts longest among all other lightnings; others may last only three waves at most while the purple one can last five waves before turning into Five Thunder Heavenly Tribulation Formation. This thing is easy to understand as long as one observes with care."

"Oh," I asked him then, "based on your observation so far, how many people under King Wu have crossed their heavenly tribulations?"

"That's hard to say," Chi Qingshuai smiled and replied. "According to my observation so far though, the strongest Yin creature under King Wu has probably already broken through Three Thunder Heavenly Tribulations or 1,500 years of cultivation level; there are no more than five such powerful beings like them out there right now. As for those who have crossed Two Thunder Heavenly Tribulations or 1,000 years of cultivation level like Yin creatures would become Yin Kings by now while zombies would turn into Black Zombies; those who have only crossed One Thunder Heavenly Tribulation or 500 years of cultivation level are too numerous to count - they're like dust particles."

"So that means there are currently at least five powerful Yin Kings under King Wu," I pondered.

"Hey, I have to say that things are not as complicated as you think," Jietou couldn't help but stand up and slam the table. "Do you have any good ideas?" I asked him curiously.

"Aren't those ghostly creatures relying on the protection of the mountain to avoid being hit by thunderstorms? Why don't we just blow up the mountain and solve everything at once?" Jietou said disdainfully.

This idea made Chi Qingshuai and me both brighten our eyes, but then we shook our heads to reject it. "What do you mean? You guys don't agree with this method?" Jietou frowned and asked.

"The bottom of Mount Modu is the entrance to Nine Yin Yellow Springs; not only does this mountain protect King Wu's Yin creatures, but it also blocks infiltration from Ghost Realm into Human Realm. If we blow up the mountain, King Wu's Yin creatures will naturally be destroyed under thunderstorm attacks. However, afterwards there will inevitably be a large number of Ghost Realm Yin creatures entering Human Realm through Nine Yin Yellow Springs - which won't solve anything but instead create bigger problems for us. Therefore, this method is temporarily unfeasible," I explained.

That's easy," JIETOU was a person who stuck to his principles. When he saw that his idea had been rejected, he immediately came up with another solution, "Why don't we find a way to block the entrance of the Nine Yin Yellow Springs?"

"Block the entrance of the Yellow Springs?" Hearing this, my and Chi Qingshuai's eyes lit up again but then dimmed.

"That's easier said than done. Do you know what kind of existence that entrance is? It can't be easily blocked. Your plan is too risky and definitely won't work," I said.

"What else can we do then? Should we just sit here and wait for death?" JIETOU became angry.

"The only option now is to find a way into the mountain and fight those yin creatures directly. Unless we can lure them out of the mountain, there's no easy way to get rid of them," I said.

"No, YiHeng, don't be so absolute in your words. I think JIETOU's plan might work," at this point, Chi Qingshuai suddenly interrupted me after being silent all along.

Hearing this made me confused: "What do you mean by that Master? Do you have a way to block off the entrance of Nine Yin Yellow Springs?"

"Although I'm not sure about it yet, I think it's worth trying," Chi Qingshuai stood up subconsciously while speaking these words. He stared blankly at Mount Modu in the distance and spoke with an infatuated voice: "It has been fifteen years; finally, I can take revenge! They will pay for everything they've done!
