My ex-girlfriend thought I was poor, so I made 100 million by betting on stones.

"We have always been curious about how Sima Shan defeated Senior Qingtian back then."

Qingye raised his head, looked at the moon in the sky, and said: "The strength of Senior Qingtian back then was so strong that we simply cannot comprehend it. With his strength, he would never be killed by a mere black puppet's sneak attack. If we have to say it, it must be... the formation."

"Master, you mean that Sima Shan defeated Senior Qingtian with this formation?"

"The black puppet is a very yin object, and Sima Shan's own spiritual power is also somewhat dark, while Senior Qingtian's spiritual power is very yang, so he is the most affected by the formation."

Qingye said, "According to the records, Senior Qingtian went there to keep the appointment, and the venue was selected by Sima Shan, so if Sima Shan set up the formation there in advance, everything seems to make sense."

At this point, it seemed like everything was connected.

Liu Yueyun suddenly realized what was going on and said, "No wonder Senior Qingtian was so strong back then, but he was defeated by Sima Shan. It turns out it was because of this."

She seemed to understand, and quickly looked at Yang Feng beside her and said, "Yang Feng, did you come to ask Master just because you guessed this?"

In fact, although no one knows who Yang Feng’s real master is, everyone knows that Yang Feng once received Qingtian’s inheritance.

Yang Feng thought for a moment and said, "No, I always feel something is wrong."

"Why, do you have any more questions?"

Aoba asked.

Yang Feng fell into silence.

After a long time, he finally said: "I think this red moon represents something more than that, and what happened back then was not that simple either."

He felt that the two words Guiguzi left for him were definitely not just related to Dian Qingtian and Sima Shan.

Guiguzi is able to predict the future, although Yang Feng doesn't know who he is.

But just by looking at his ability to shuttle through the barrier and come and go without a trace, Yang Feng could feel that his strength was definitely above Qingye and others.

Qingye could sense Yang Feng's confusion and said, "But the formation you mentioned actually only exists in theory, because to construct such a formation, the materials needed are not ordinary formation cornerstones."

"Then you mean..."

"I'm afraid we'll need some sunken wood."

"I...I don't think I've heard of this."

Yang Feng was confused.

Liu Yueyun immediately seemed to have found an opportunity to show off, and said with a smile: "Finally, there is something you don't know. Otherwise, if you beg me, I will tell you."

"Xiaoyun, stop messing around."

Qingye was also somewhat helpless and said, "Since you have said it, explain it to Yang Feng."

"Oh, alright."

Liu Yueyun began to speak seriously, "In fact, sunken wood is a kind of wood that has been formed into a kind of stone after millions of years or even longer. According to current science, this is not strictly considered wood."

"Is this kind of petrified wood called petrified wood?"

Yang Feng remembered that he had seen it in science before.

Liu Yueyun nodded immediately and said, "Yes, this is all due to geological activities in the ancient times, such as volcanic eruptions, which quickly buried the wood. Then, due to geological actions, the wood was continuously filled with materials, and after being compacted and solidified, it formed a special stone."

"I see. In that case, this kind of stone shouldn't be uncommon, right?"

Yang Feng knew.

Although the conditions for the formation of this kind of stone are very harsh, they are not extremely difficult.

Liu Yueyun looked disdainful and said, "If it were really that simple, my master wouldn't have told you."

“What other procedures are needed?”

"To put it simply, the kind just now is just an ordinary petrified wood. Sunken wood is a more special kind. First of all, the wood must be spiritual wood that can be attached with spiritual energy in ancient times."

Liu Yueyun continued, "You should know that in ancient times, the density of spiritual energy, including the composition of the air, was different from what it is now."

"Yeah, I know, for example, the oxygen percentage was high at that time."

"That's right. So at that time, some special types of wood would have some spiritual energy attached to them. Then, in environments such as volcanic eruptions or earthquakes, they would be quickly buried underground to ensure that the spiritual energy did not dissipate."

Liu Yueyun said, "Then, just like a normal petrified wood, it began to change continuously, but this is only the first step."

"and then?"

"Then they need the nurturing of spiritual energy, just like there is often a pulse of spiritual energy underground. After being nourished by spiritual energy, these special petrified woods need more than a million years to gradually turn from stone into wood. This kind of wood is called sunken wood."

Liu Yueyun's words made Yang Feng a little stunned.

If this is the requirement standard, Yang Feng dare not think of any way to find this kind of stone.

Not only would it take millions of years, but the conditions were also too harsh.

Seeing Yang Feng like this, Qing Ye also said: "Because the sunken wood has been nourished underground for a long time, it actually hides a huge amount of Yin energy. However, this Yin energy does not hurt people, but can continuously provide pure power to the formation."

"In other words, to build this formation like the red moon, there is no substitute?"

"If you want to achieve the effect of Red Moon, there will probably be no substitute."

Qingye shook his head and said, "In fact, this sunken wood occasionally appeared in ancient times, just like my master's ancestors have recorded it. However, by our time, there are basically not many left, and it can almost be said that it can't be found."

She also felt a little regretful when she mentioned this.

For top-level formation masters, sunken wood represents many formations, but they can do nothing without the raw materials.

It's hard for a clever woman to make a meal without rice.

After hearing this, Yang Feng just wanted to have a good laugh and said, "Although it is so difficult, I think the two words Red Moon should not be that simple. Maybe there are other explanations."

"Is this Guiguzi's reminder to you?"

Qingye had already seen through Yang Feng's thoughts.

Yang Feng was a little surprised, but soon nodded and said, "Yes, Senior Guiguzi once reminded me of these two words, Red Moon."

"If he said so, there must be a reason."

"So I have been looking for this. As for this formation, I just think it might be useful in the future."

Yang Feng didn't say his final thoughts.

Qingye could sense that Yang Feng must have other purposes in asking him this.

"It seems that the previous agreement has little impact on you. It seems that Xiao Qiuping's worries are a bit unnecessary."

Aoba mentioned this name.
