Immortal cultivation starts with copying.

The matters that Lin Changfeng and several senior masters who had reached the state of Divine Transformation were all confidential. Chen Yunhao certainly knew that such confidential matters could not be spread to outsiders at will.

However, for him, this was just a fun story and he couldn't influence the course of events.

The order has been given from above, so Thunder Mountain has to carry it out. However, this matter will not be done in a high-profile manner. If the whole world knows about it, how can it be done?

Don’t think that only Thunder Mountain has support in the upper realm. There are many sects with a history of tens of thousands of years that have support in the upper realm.

However, this is a very difficult task. Without a specific goal, it is like looking for a needle in a haystack. I am afraid that in the end it will be a waste of time.

Because he had to arrange a secret search, Lin Changfeng encouraged Chen Yunhao a few words and then sent him away.

After leaving the small secret realm, Chen Yunhao first went to the Sutra Library and headed straight to the third floor.

Ever since this outing when he came into contact with the vital energy of heaven and earth, Chen Yunhao felt the magic of the vital energy of heaven and earth.

So he had to look for relevant classics, and also learn some knowledge related to the transformation of the spirit in advance.

There are very few classics stored on the third floor of the Sutra Library, and there are also very few relevant records. It took an hour to find two classics.

In fact, Chen Yunhao could have gone and asked his master Lin Changfeng, but he was afraid that his master would scold him for being too ambitious and wanting to fly when he had just learned to walk.

After taking the two books, Chen Yunhao flew all the way back to the cave in Thunder Mountain.

His focus has been on this in recent times. Since he has been promoted three levels in just three years, he is afraid that his foundation is unstable, so Chen Yunhao has not thought about advancing in the past two years.

Just as I was about to set up a restriction at the cave entrance, I heard the faint voice of the spirit of the weapon.

"You little brat, time is running out...!"

Chen Yunhao was stunned when he heard this.

"Senior, my advancement speed is fast enough, right? If I go any faster, I'm afraid it will be harmful if I force things to go too far!"

“Not fast enough, but mainly because I’m running out of time….”

The spirit of the weapon chuckled, with a hint of solemnity in its tone.

"Senior, do you feel something is wrong? I will definitely do my best..."

Chen Yunhao was startled. The ancient mirror was his greatest reliance and he absolutely could not afford to make any mistakes.

"What do you think those idiots in the spirit world are looking for?"

“Could it be…?”

Chen Yunhao only felt as if a flash of lightning flashed through his mind, making his head buzz.

"As early as when you first participated in the beast tide, the demon and human races sent people to the lower world. Now it's the sea tribe, and in the future it will even be the demon world..."

Every time the spirit of the weapon spoke, Chen Yunhao's heart tightened, and an invisible sense of oppression arose spontaneously.

"Senior, is there any solution?"

Chen Yunhao took two deep breaths and suppressed the fear in his heart.

If I were to say I was afraid, of course I was, but at the same time, there was also a hint of excitement.

This is a treasure that all the races in the upper realm are trying to find. Even if the ancient mirror is not a fairy weapon, it is still a treasure that defies the heavens.

Anyway, it is impossible for him to give up the ancient mirror unless he dies!

"My original strength hadn't recovered, and I leaked some of my Qi. Now that my cultivation has recovered somewhat, I can still conceal this side's secrets, but it's not perfect..."

The spirit of the weapon paused and then continued.

"If a cultivator proficient in tracing the origin of the spirit world comes down, there's a 50% chance that he'll be able to find me. Besides, I have to recover some strength as soon as possible, otherwise, if you and I go to the spirit world in the future, we'll be more easily exposed."

"Senior, please tell me what you think. I will do my best to cooperate with you."

In the final analysis, the weapon spirit's strength recovered a little slowly, so Chen Yunhao decided to help the weapon spirit recover some strength first. It didn't matter if his own cultivation was slower.

"Energy, all kinds of energy..."

"Senior, do you have a target? I will take you there."

"There's no such thing as a target. I can only sense it when I get close."

"this……."

I really stumped Chen Yunhao, as he knew that weapon spirits were quite picky about their energy requirements.

For example, spirit stones are also a kind of energy, but spirit objects will not devour them.

The energy absorbed by the weapon spirit is very diverse, including the five elements energy and space energy, and there is really no specific target.

Chen Yunhao lowered his head and thought for a while, and made a decision in his heart.

"Please wait a moment, Senior..."

Chen Yunhao turned and left the cave, running towards the Sutra Library again.

He remembered seeing many miscellaneous notes about the Boundless Sea on the first floor of the Sutra Library.

It records many things that have happened in the Boundless Sea and some of the peculiar landforms that exist now, as well as some famous dangerous places in the Boundless Sea.

These miscellaneous notes were of no great help to Chen Yunhao's cultivation of immortality, so he chose to ignore them at the time.

There is a saying in the world of cultivating immortals: the more dangerous the place, the greater the potential rewards.

According to Chen Yunhao's personality, he is cautious and afraid of death. He never takes the initiative to get involved in anything or any place that has anything to do with danger.

But this time I can't cherish my life. I have to fight for the ancient mirror, which is equivalent to fighting for myself.

After borrowing three thick volumes of Boundless Sea Notes from the Sutra Library, Chen Yunhao did not return directly to Thunder Mountain.

Almost all of Chen Yunhao's belongings were in his personal space, the mustard bead, and there was nothing left in the cave, so he simply decided not to go back.

Moreover, with his current level of cultivation, he basically has to rely on himself to perform freely, and his master won't keep an eye on him every day.

So if he wanted to leave Thunder Mountain, he didn't need to say goodbye to anyone.

However, Chen Yuanhao still went to visit his third senior brother Xu Chao, saying that he had been in seclusion for many years and wanted to go out and gain some experience.

This means that he has left information about his trip, and he also left a soul lamp in Thunder Mountain.

Before night fell, Chen Yunhao rushed to Leixiao City, changed into ordinary clothes, and stayed in Leixiao City for one night.

This night I mainly spent researching where to go. I really had no goal and felt completely in the dark.

Chen Yunhao almost stayed awake all night, constantly flipping through one of the miscellaneous notes and communicating with the spirit of the weapon.

However, the initial plan is to go from near to far, starting from the Thunder Sea.

The three miscellaneous notes that Chen Yunhao borrowed from the Sutra Repository were not chosen randomly, but were selected according to the time period in which the notes were recorded.

For example, the oldest of the books can be traced back to five thousand years ago.

There is another one written by a predecessor three thousand years ago, and the last one is just less than a thousand years old.

Therefore, the three miscellaneous notes contain both old, medium and new ones, mainly for the purpose of verifying each other.

For example, if a place is recorded in all three miscellaneous notes, it is likely that it still exists today.

If only one of the books has a record and the other two do not, he will focus on the latest record.

Mutual verification can save him a lot of time, otherwise the boundless sea is so big, it will take him forever to search aimlessly!
