Several elders of Yakuodo came to do exactly what Kagura Chizuru was doing.

Although several elders were unable to refine the life-sustaining elixir, they never gave up.

In addition to desperate attempts, I have been constantly looking for classics.

Just now, they found a few ambiguous records in an extremely old book.

According to the records in that ancient classic, in ancient times, there were indeed many sects that were good at alchemy, and they were able to refine this kind of special life-sustaining pill.

It's precious, but it's not impossible.

In that old classic, the names of those ancient sects that specialized in alchemy were even mentioned: Danxin Sect, Yuding Gate, and Wancaotang!

Several elders of the Medicine King Hall didn't know whether this information was useful to Li Fan, but as long as they found something related to this, they would report to Li Fan as soon as possible.

For the Danxin Sect, Yuding Gate, and Wancaotang mentioned in this ancient classic, even the oldest elders of Yaowangzhuang have never heard of it.

Danxinzong, Yudingmen, Wancaotang......

Li Fan groaned.

Yakuodo has been passed down to the present day and has a history of thousands of years.

Since the names of these three sects can only be found in the oldest classics of Yaowangzhuang, it means that the existence of these three sects is far earlier than thousands of years ago.

Maybe it existed 10,000 years ago, or even tens of thousands of years ago.

A sect tens of thousands of years ago......

How did Li Fan find it?

No matter how strong Li Fan is, it is impossible to reverse time and space and go to tens of thousands of years ago, right?

Even in the classics left by the Heavenly Absolute Immortal Venerable, it was mentioned that if he cultivated to the time of the Tribulation Ascension, he might have a certain chance to be able to reverse time and space, but for the current Li Fan, it was too ethereal!

Li Fan has worked hard to cultivate so far, but it is only the Jindan Realm.

And to cultivate to the tribulation period, there are also Yuan Infant, Turning into Gods, Returning to Void, and Merging Dao in the middle!

What's more, the difficulty of cultivation, the more you reach the later realm, the more the difficulty has increased exponentially!

Let's just say that this time Li Fan built his own foundation realm and broke through to the Jindan realm.

If it weren't for all kinds of coincidences, if it weren't for the fact that Li Fan had so many top-grade spirit stones on his body, if it weren't for Ouyang Tianfeng's desperate use of the Five Thunder Array to attack Li Fan, if it weren't for the power of faith of the millions of college students that Li Fan saved, I'm afraid that Li Fan's promotion to Jindan this time would definitely not be so smooth!

Therefore, the difficulty of the five realms above Jindan, such as Yuanying, Turning into a Spirit, Returning to Void, Merging the Dao, and Crossing the Tribulation, can be imagined!

So, this road doesn't work!

Li Fanzheng shook his head helplessly, but suddenly a flash of inspiration flashed in his mind.

Since there is no sect on earth that can refine life-sustaining pills, what about the spirit world?

What about the spirit realm from which Ouyang Tianfeng came?

According to the inheritance of the 'Gatekeeper', as well as Ouyang Tianfeng's own words, in the spirit world, the original aura concentration was far stronger than that of the earth, and there were many powerful immortal cultivation sects among them!

Among them, there must be a sect that can refine life-sustaining pills!

Moreover, the spiritual world used to be full of spiritual energy, even if it has begun to decline now, but the emaciated camel is bigger than the horse, and that kind of elixir can only be found in the spiritual world!

In that case, what's the harm in going to the spirit realm by yourself?

Li Fan instantly saw hope.

Since he had decided to go to the spirit world, Li Fan began to make arrangements.

Now that he is supported by Li Fan's blood, Kagura Chizuru can still maintain his life, and Li Fan is not in a hurry.

First of all, I found the green dragon.

At this time, the green dragon's eyes were still unable to see, and the ability in his eyes was completely lost.

"Tell me about your abilities!"

Li Fan asked.

"My ability has to do with the law of cause and effect. ”

Qinglong nodded and began to speak slowly.

The so-called law of cause and effect means that everything has a cause and effect. For any event, there must be a reason for it to happen, and it must also be the cause of the next thing. ”

"According to the theory of classical science, there is a law of cause and effect in everything in the world, for example, the reason why I appear on the top of Xiangyue Mountain now is because I was blind in the previous war, so Li Fan, you specially asked me to come to Xiangyue Mountain!"

In other words, the essence of the law of cause and effect is that everything has a cause before there is an effect, and it is absolutely impossible to reverse the relationship between cause and effect!

"However, according to the latest modern quantum technology and other research, the law of cause and effect is reversible!"

"The law of cause and effect is reversible, which means that a thing can first have an effect, and then determine its cause!"

"For example, in the previous battle, my absolute strength was far from Ouyang Tianfeng, but I was able to restrict his movements in a short period of time, making his speed extremely slow! ”

"I first decided to restrain Ouyang Tianfeng, and then I came to find a reason!"

Hearing this, Li Fan frowned, "Then the reason is that your eyes are blind?"

"Not bad. Qinglong nodded and continued, "My blindness is the reason why I restricted Ouyang Tianfeng's actions!"

"On the surface, these two events are unrelated and cannot constitute a causal relationship at all!

"What theory?" Li Fan frowned.

"Butterfly effect!" Qinglong said: "A butterfly in Xia Kingdom can cause a tornado in the United States with a flap of its wings!

"The butterfly flapping wings of the Xia Kingdom itself is just a trivial matter, but under the butterfly effect, the act of flapping the wings of the butterfly can be amplified layer by layer, passed layer by layer, and finally, a tornado will be formed in the United States!"

"Then this time, the result of restricting Ouyang Tianfeng's actions, the reason why you are blind and not anything else?"

Qinglong shook his head and said with a wry smile:

"That's because the difference in strength between me and Ouyang Tianfeng is too big, and what I want is to take effect immediately!"

"If I change someone who is far weaker than Ouyang Tianfeng, if I want to restrict his movements, it will not cause me to be blind, or even if it is Ouyang Tianfeng, if I want to restrict his movements at some point in a few days, it will not cause me to go blind. ”

"It is precisely because Ouyang Tianfeng is too strong, and the time I ask to achieve the result is too short, so I can't find any other choice other than the reason that I am blind. ”

"This is the price of my ability!"

"This is the price of reversing cause and effect!"

"If the result I set at that time was more exaggerated, such as directly injuring Ouyang Tianfeng, I'm afraid I would have died on the spot. ”

"If I set an even more outrageous result, such as letting Ouyang Tianfeng die directly, it will already be far beyond my ability, even if I pay for my own life, it will not be able to achieve it!"

After Qinglong finished speaking, he faced Li Fan with a calm face.

It seemed that he had come to terms with the fact that he was blind and incapacitated.

"It seems that the price to be paid for this ability to reverse cause and effect is also not small!"

Li Fan shook his head and said.

"Yes! Everything has a price, even the ability to reverse cause and effect!"

Qinglong nodded.

"My daughter, Li Buregret, has similar abilities to you. ”

Li Fan said suddenly.

"What?"

Qinglong was shocked.

"Moreover, it seems that your ability can only be effective if you see directly with both eyes, right? My daughter's ability does not seem to have this limitation. ”

Li Fan said again.

"Yes, so I usually wear glasses to prevent accidentally using my abilities!"

Qinglong nodded.

"It seems that the ability to not regret is stronger than you......"

Li Fan's face did not have a trace of joy, but was full of worry:

“…… The more powerful the ability, the greater the price!"

"That's true. Qinglong also nodded.

"In this case, I want to ask you to be my daughter Li Buregret's teacher. Of course, your responsibility as a teacher is not to teach her how to use her abilities, but to teach her how to limit her abilities. In return, I will do everything I can to heal your eyes!"

Li Fan looked at Qinglong Dao.
