It was also a coincidence that Cai Quan originally wanted to test Lu Yao's strength, but who knew that this mistake was to solve some mysteries for Lu Yao, at that time, Cai Quan originally wanted to pretend to accidentally pour the tea to Lu Yao, and then see what Lu Yao's reaction was, and Lu Yao's sleeves were blocked by a flick of his sleeve.

Lu Yao originally planned to teach Cai Quan a small lesson and whisk the tea on Cai Quan's body, but Cai Quan flashed and dodged a small part of the tea, and that small part of the tea happened to splash on the paper with strange patterns.

When the paper meets water, it is nothing more than soaking, but the strange thing is that this time the tea splashed on the paper is very magically along those strange lines and slowly disperses, and finally when the water traces are soaked in all the lines, it seems to evaporate out of thin air, and it disappears, but the paper is intact.

All this did not happen in an instant, and at that time, Xing Zhongtian, Wu Bo and Xing Chuqing were all reprimanding Cai Quan's behavior, only Lu Yao noticed this process, and it was also because Cai Quan had not left at that time, so Lu Yao did not say it, and waited until Cai Quan left before he briefly told the three of them what had just happened.

It's just that after Cai Quan left, there were no traces of being soaked in water on the piece of paper, and Lu Yao couldn't explain it very clearly for a while, so he could only leave first after discussing it.

Back at the residence, Lu Yao immediately found another glass of water to test, but this time the puzzling thing was that the situation did not appear again, the whole paper was soaked under a glass of water, and the handwriting that traced the lines also became messy, and no clues were found.

What the hell is going on?

Lu Yao was puzzled, he couldn't find any clue after sitting there and meditating for a long time, and finally after some struggle, Lu Yao could only use the stupidest method, which was to copy those lines again.

Although this time it was the second time, it still took Lu Yao a long time, and when he finished the last stroke, he felt very tired, as if his brain had been hollowed out by something. However, fortunately, this is the second time, and Lu Yao has nothing to worry about, so he packed up everything and began to regain his strength.

An hour later, Lu Yao felt refreshed, so he immediately found another glass of water to try again, although this time the situation appeared again, but it was far less shocking than the first time, and when the last trace of water soaked the last circle of lines, the paper was still somewhat wet, not so dry.

However, fortunately, this attempt was not without gains, at least Lu Yao engraved all the traces of water soaking all the lines in his mind, and when everything was over, Lu Yao rehearsed the whole process in his mind several times to see if he could find some clues.

After doing all this, the sky gradually darkened.

But Lu Yao didn't want to rest at all at this time, got up and went to find Xing Zhongtian, and went to see the half-dead fairy grass again.

This time, Lu Yao brought pen, ink, paper and inkstone, and tried to copy the lines on the two remaining leaves on the spot.

"Old valley master, it may take a little longer, if you feel tired, you can go back to rest, and I will naturally look for you when I finish." Lu Yao said to Xing Zhongtian before starting.

"No need, Master Lu is busy with the affairs of our Medicine King Valley, where can I, as the master, go to rest alone." Xing Zhongtian waved his hand again and again, and said, "Besides, I can also run errands for you here, if you need anything, just let me know, I will send someone to prepare." ”

"Alright then, then I'll get started." Lu Yao knew that no matter what he said, it would be impossible for Xing Zhongtian to change his mind, and to be honest, he also hoped that Xing Zhongtian would stay here, at least this would give Xing Zhongtian a little more peace of mind.

After that, Lu Yao took the pen and paper and began to copy.

The texture of the two leaves was completely different, which Lu Yao had discovered before, but he never expected that something more strange would happen.

Although it took a lot of energy for Lu Yao to copy the lines on the withered leaves before, it was finally completed in the end, but this time, Lu Yao just started copying, just dropped the first stroke, and felt a buzz in his head, and then his eyes went black.

"Lu Gongzi, are you okay?"

After Lu Yao woke up, he saw Xing Zhongtian holding his waist at the moment, trying his best to support his body, and this was the fundamental reason why he didn't fall down again in the first place.

"It's okay, I just feel a bad headache!" Lu Yao smiled bitterly and said.

"I think we'd better forget it, this thing is weird, it's really not good, let's find another way!" Although Xing Zhongtian was not as strong as Lu Yao's strength, he also knew what was going on when he suddenly felt a headache at this time, and it must be the result of a heavy blow to his mental power.

For an immortal cultivator, the damage to the body can be recovered through cultivation, but the damage of mental power is not so easy to heal, at least it will not be able to exercise for a few days, and at worst it is likely to lead to a regression in strength, a drop in the realm, and even a lifetime of cultivation that cannot be advanced.

No matter which situation it is, it is not what Xing Zhongtian wants to see.

Xing Zhongtian's kindness Lu Yao naturally understood, but he was not such a person who could be defeated so easily, so he pondered it carefully and said, "I think I should be able to try it once." ”

"Still trying?" Although Xing Zhongtian didn't know Lu Yao's temperament very well, he also knew that he was not a stubborn person, and he thought that his words had given him a step, and Lu Yao should stop this crazy move, but who knew that Lu Yao would still try.

"I think I should try again, and if it ends up and fails, I might really give up!" Lu Yao said with a smile.

"Then ......, okay, let's say okay, let's try once, if it still fails this time, we will end it immediately, I can't allow you to have an accident in our Medicine King Valley." Xing Zhongtian had no choice but to compromise, but he also resolutely expressed his attitude.

"Hmm!" Lu Yao nodded, and agreed.

This time, Lu Yao was extra attentive, when he picked up the pen, he was not in a hurry to put down the pen, but now he roughly rehearsed it in his mind, and at the same time used the exercises that were obtained from the wordless heavenly book to practice spiritual power, and finally put down the pen when everything seemed to him to be a matter of course.
