After doing this, he began to run wildly, God knows how big it was, as if he had lost the concept of time, and only knew how to keep walking along the human tracks. During this time, he kept thinking about the problems that the two old men said.

What is guidance and what is control?

Every day he thought about it at night, but he didn't know that the enemy behind him had chased that step, and he kept running wildly.

When you are tired, you can sit for a while, rest for two hours, and drink some osmotic water from the stone wall when you are thirsty. As for food, there is not much food needed for the ninth layer of Qi refining, as long as you can meditate and cultivate, it is no problem not to eat for more than 100 days.

Lin Xueyue's clone does not stop behind to spy on the enemy, or lead the enemy astray. From time to time, he felt that the clone was destroyed, and what made Zhang Yu depressed was that no matter how the group of people led them away, they would quickly return to the right path.

In the end, Zhang Yu simply didn't send Lin Xueyue to monitor, and fled with all his heart.

I don't know that he ran in the belly of the mountain for a few days, and one night he suddenly thought of guidance and control, could it be that the silver needle is control, the acupuncture point is the valve, the meridian is the water pipe, and the yin and yang qi should be the water flow.

If you want to change the flow of water instantaneously, what if you prick the silver needle into the corresponding position first, and use your muscles to control the depth of the silver needle?

Zhang Yu was very curious about this idea, so he did an experiment, piercing a silver needle on the acupuncture point on his hand, and the position of the needle was slightly shallower than usual.

According to the standard course of Chinese medicine and acupuncture, this method is ineffective and has no meaning.

Zhang Yu controlled the muscles, let the muscles gently wrap the needle tip, and pulled it downward, to his surprise, the muscles were not so obedient, and the experiment failed!

He thought about it, and then deviated the acupuncture point a little more, even worse, it didn't make any sense!

Zhang Yu bit his lip, he vaguely felt that his idea should be correct, he did it desperately, even if he failed, it was nothing, but it felt very interesting.

I don't know how many needles I put on myself, even if he has super healing ability, he can't withstand his complicated physical experiments.

There were many holes in his arm, and he finally found a little way out.

The position of the acupuncture point with the silver needle must be just right, and then the muscles and yin and yang qi are operated at the same time to suck the silver needle, only in this way, he found that he could actually use the needle to pierce the four acupuncture points at the same time, coupled with his hand speed is particularly fast, Zhang Yu became excited when he thought of this.

Feeling the four acupuncture points of the arm at the same time is indeed the correct method. If the two old men knew that Zhang Yu used this method, they would definitely be surprised, and then shouted genius.

Controlling the flow of acupuncture point muscles and body true qi can be used by ordinary cultivators, and if it is popularized, then this killing intent can be taught in batches. If a cultivator of a sect could use Killing Intent to forcibly improve his cultivation by one level, what a terrifying thing it would be.

It's a pity that Zhang Yu didn't think about this aspect at all, and his idea also needs a lot of experimentation and improvement. But now this is not a good place for experiments, the future is bleak, and there are chasing soldiers behind, which makes Zhang Yu a little regretful.

After thinking of this good solution, Zhang Yu did not stop, but continued to think.

The killing intent is broken, and he can enter and exit as he wants......

He suddenly thought about a question, if he could use the silver needle to control the acupuncture points and the direction of qi and blood, then could the second layer of the Killing Intent Decision be entered at will?

This is a very interesting topic, and it is also a good way to solve the low combat power of the Celestial Master Clan.

While he was meditating, he tried to enter the second layer of Killing Intent, and found that the flow of qi and blood was more complicated, and it involved the operation of the five internal organs and other meridians.

Just when Zhang Yu had a headache, suddenly Lin Xueyue said happily: "I found the exit!"

Zhang Yu was overjoyed, he hurriedly tore a strip of cloth from his clothes and prepared, after all, staying in the dark for too long is particularly bad for his eyes. Suddenly switching from dark to light, the eyes are easily blind.

With Lin Xueyue's guidance, he walked for about dozens of minutes and vaguely saw a light in front of him.

Zhang Yu hurriedly blindfolded his eyes, switched the Yin and Yang Pupil Technique, and followed Lin Xueyue forward. Soon after, he walked out of here and found that this was also a deep valley, and he could see a glimmer of heaven when he looked up.

Zhang Yu was overjoyed and hurriedly jumped on the rocks protruding from the cliff, and with his jump, he quickly jumped out of the valley.

Xie Yong was originally an IT man, sitting in the office every day, and was finally pulled out to climb the mountain for exercise, but he encountered this incident.

Hearing that this crack was a ray of heaven, Xie Yong and his companions made a bet that they could walk to the edge of the cliff and look down at the cliff.

As soon as he walked more than ten meters to the cliff, he felt the cold wind here, and Xie Yong's earliest courage disappeared. Probably because he didn't want to hear the ridicule of his companions, he still stubbornly walked towards the edge of the cliff.

He knew that he had just reached the edge of the cliff when he heard something, and then an unkempt and tattered wild man jumped up at once, and frightened him so that his legs went limp, and he sat down on the ground, and his glasses fell to the ground.

He hurriedly picked up his glasses and put them on, his teeth trembled with fright, and he swallowed his saliva with difficulty and asked, "You...... Are you a human or a ghost?"

"Of course I'm human!" the wild man said suddenly, revealing his white teeth, but with his appearance, this scene was a little too terrifying, and Xie Yong, who had not experienced anything, simply rolled his eyes and fainted.

"Haha, it turns out that there is such a thing, I didn't expect you to fall off the cliff and survive, it's really lucky!" A few minutes later, the companions who came from a distance were relieved when they heard the wild man's explanation, and they quickly woke Xie Yong up.

After washing his face with water and changing his clothes, the wild man revealed a delicate face. Zhang Yu couldn't cry or laugh, he couldn't imagine that jumping off the cliff would encounter such a thing.

After eating something, Zhang Yu made up an excuse, saying that he was a donkey traveling up the mountain, and he survived because he accidentally fell off a cliff and hung on a certain branch. He walked along the bottom of the valley for a long time and suffered a lot, but fortunately he liked rock climbing, so he found an opportunity to climb up.

"I'm really sorry to scare you!" Zhang Yu said apologetically.

"Hehe, it's okay, it's just too sudden, in fact, I'm quite timid. Xie Yong said self-deprecatingly.

"By the way, where is this, what time is it today?" Zhang Yu asked.

"This is the mountainous area on the edge of Shenlongjia, and today is April 15th. Xie Yong said.

I didn't expect to walk to the edge of the Shenlong Frame, from the time he arrived in the Heavenly Medicine Valley to today, it was more than two months, except for staying in the Heavenly Medicine Valley for more than half a month, it was difficult for him to stay underground for a month and a half. Thinking of this, Zhang Yu was startled, his mobile phone was out of battery for a long time, and he wanted to borrow their phone to use it, but unfortunately there was no signal here in the mountains, so Zhang Yu had to follow them.

Fortunately, they had finished climbing the mountain and were just walking back, so they drove Zhang Yu a little bit and took him away from the Shenlongjia Mountain.

Looking at the rolling Shenlong Frame, Zhang Yu breathed a sigh of relief, I don't know what happened to Zheng Xue'er, is she still locked up in the Heavenly Medicine Valley? There are two old men, so Jin Moyuan shouldn't do anything to them!

This is a small county town called Chengxi County, and after Zhang Yu inquired, he found that it was still hundreds of kilometers away from the imperial capital.

After thinking about it, he called Li Song, then he knew that he didn't answer the phone, could it be that he was still in southern Xinjiang? Zhang Yu didn't stay after hanging up the phone, and rushed to the imperial capital day and night, and he decided to take the research report of the Heavenly Medicine Valley to his senior brother to see.
