The next morning, Bai Sheng said goodbye to Hachiyu Hanya.

Hangu Pass fell into the hands of the Tangut people and urgently needed to be recaptured, and the leisure and elegance of qin, chess, calligraphy and painting had to be put aside, of course, the only reason that allowed him to take a break from his busy schedule and stay in this valley village was to learn the method of organ information, and its fundamental purpose was to open the underwater stone gate of the Trap Island.

It's better to ask for others than for yourself, you just need to learn Feng Asan's skills, so why take him to run around with him?

Hangu Bayou repeatedly failed to keep him, so he had to send Bai Sheng and Liang Hongyu to the entrance of the village, saying that these eight friends would welcome Bai Sheng's brothers and sisters to come again at any time.

Wang Zhe's mother and son also followed Bai Sheng to say goodbye, but Huang Kunpeng's mother and son planned to stay in seclusion, which was far away from the war and would not be disturbed by the world, and it was the safest.

After a farewell, Bai Sheng led Wang Jin and Fang Baihua to return to the natural maze and learned Feng Asan's skills, of course, this maze could not trap him, and there was no need to ask Feng Asan himself or Huang Kunpeng to guide the path.

This natural maze is actually caused by human visual errors.

It is undeniable that the eye is the most direct and most reflective of the human sensory organs. As the saying goes, "hearing is false, seeing is believing", this statement is not only the experience of thousands of years, but also has been regarded as the truth by many people.

But is what the eye sees really the thing itself? The answer is not necessarily.

In our daily life, people often use the expression to prove the truth of a thing: This is what I saw with my own eyes, but even what I see with my own eyes may not be real, because the eyes of animals have limitations, that is, there are errors in vision.

A few examples can prove the existence of visual errors:

For example, when people are dressing, those who wear horizontal stripes always look fatter, while those who wear vertical stripes give people the impression that they are a little thin.

Another example is the strange slope in the world, that is, the kind of area that appears to be uphill but does not need power, and the area that appears to be downhill must be driven by power in order to move forward.

Another example is the blind spot of anti-slope artillery fire on modern fortifications, which allows the enemy to see the position but never hit the target.

Finally, magic tricks such as cutting a living person into three pieces are performed using the principle of visual error.

Beyond this valley, there are many natural scenery that can cause visual errors, which seem to be real, but if you follow their appearance, you will not be able to go where you can see, and those areas that seem impossible to pass like water curtain caves are a smooth road.

These scenes have been transformed by Feng Ah San, and some key points are set up with mechanisms, some trees and rocks that can be moved, so that people cannot change their orientation or feel the reality at close range, and they have become a natural maze.

What Huang Kunpeng calculated before was the traps added by Feng Asan, as long as he found these traps, he could find the mountain village in the valley through the maze.

And Feng Asan's ability is by no means so superficial, the setting of the entry and exit mechanisms is completely different, at this time, even if Huang Kunpeng wants to come out, he has to re-extrapolate it again, but Bai Sheng has already mastered the principle, so he led everyone all the way forward unimpeded.

Fang Baihua followed behind Bai Sheng, silently noting down the path as she walked, when she entered yesterday, she had already written down the key points calculated by Huang Kunpeng, her idea was to wait for Bai Sheng to leave and then return to the mountain village according to Huang Kunpeng's route, and be sure to invite Feng Asan to Hangzhou Fang La.

Of course, her little trick couldn't hide from Bai Sheng, Bai Sheng had long known that Fang Baihua would not give up if he didn't kidnap Feng Asan, but he only pretended not to know, and deliberately took everyone to a wrongful road, and easily moved some grass, trees, forests and stones, and changed Feng Asan's original entry setup.

The changes of these devices will not cause trouble to Feng Asan, as long as Feng Asan wants to go outside, he will find that the changes of these devices, it doesn't matter whether they are changed back or not, in short, Feng Asan can't stop Feng Asan from coming and going freely.

But if Fang Baihua wanted to re-enter again according to Huang Kunpeng's move, it would be impossible, he could only be trapped in this maze, and as for whether he would be trapped, he could only hope that Feng Asan would find out that there were people in the formation, and whether he would let them out.

Sure enough, the group walked outside the maze, first the Wang family mother and son said goodbye to Bai Sheng, and then Fang Baihua said that he wanted to rest nearby, and he couldn't accompany Bai Shaoxia to Hangu Pass.

Bai Sheng knew it well, and he didn't break it, and Liang Hongyu and Wang Jin went to Tongguan with eight hundred cavalry, and before rescuing Hangu Pass, the first thing to counterattack was Tongguan.

Not to mention that Fang Baihua almost starved to death when he returned to the maze, but only that Bai Sheng and his party were on the way to Tongguan, Bai Sheng found that Liang Hongyu was depressed, so he asked what was going on.

Liang Hongyu has not been in high spirits since yesterday, just to let Hangu Bayou accept Bai Sheng, so she forced a smile, talked about piano and painting with Bayou, and went to sleep after finding out that Bayou and Bai Sheng were having a hot fight.

The reason for her low interest is, of course, that the internal power given to her by the "gods" is gone, and there is no sign of recovery until now, she feels that she is a person who has been abandoned by the gods.

Could this person who gave me internal strength be Lu Dongbin? Because she had just met the omnipotent Lu Dongbin, she felt that Lu Dongbin had a great possibility of helping her.

So when Bai Sheng asked her, she pondered for a while before replying: "Brother Bai, Hongyu's internal strength is gone, and there is no hope of revenge for killing her father after all." ”

She said that she had no hope of revenge because she had promised to give her a seed master, and whether she took revenge on her father or not, she would definitely return to Yanzhou City in two months to accept the disposal of the soldiers and civilians in the border city.

This promise is different from the usual lies, it is equivalent to an oath, it cannot be broken, people in this era believe in the oath, and Liang Hongyu is no exception.

Bai Sheng actually guessed the reason why she was unhappy, and asked just to confirm it, and after confirming it, he also pondered for a long time before saying, "Actually, the internal force in your body was passed on to you by me." ”

"Huh?" Liang Hongyu was taken aback, but remembering the spectacular scene of Bai Sheng dancing with an iron rod to knock down 800 people yesterday, she couldn't help but believe it, recalling the warm heat flow in the dantian in her body, she was shy and couldn't help but be moved at the same time, and said: "Big brother, why are you so good to me? Little sister, I can't repay it!"

Bai Sheng sighed: "Don't say anything about whether I'm good to you or not, I didn't ask you anything for being good to you, now I just want to ask you, do you want my internal force to stay in your body forever?"

"What?" Liang Hongyu was stunned, and only came back to her senses when the two of them ran out of the war horses together, and asked, "Is there still such a way?"

Bai Sheng said: "I don't know if this method will work, even if it works, there are a few problems that bother me, but since you are so eager to take revenge, I will ask you if you want to give it a try." ”

Liang Hongyu was extremely moved, wet her eyes and said: "Of course I want to try, but if your internal strength is given to me, big brother, then what should you do? If you lose all your martial arts because of this, my little sister will resolutely not try!"

Of course, she didn't know that Bai Sheng's internal strength could be restored by "charging" through the stars at night.

Bai Sheng said: "I gave you my existing internal strength, and I can recover it myself, but I don't have to worry about this, there are a few other things that are not easy to solve." ”
