Zhao Xinlong brought Feng Yu to Tongshulin and began Wu Yuan's basic training, precision training.

"The use of dark energy is actually the release and contraction of the martial element in the body," Zhao Xinlong said, "I brought you to Tongshulin, in order to further learn to continuously release the martial element in the body, and have accurately controlled the release of the martial element in the body each time, understand?"

Feng Yu nodded in understanding.

Zhao Xinlong walked to a tall paulownia tree and said, "The training of climbing trees is the most basic, at first you can be like me, use your hands and feet, release Wu Yuan on your hands and feet, so as to absorb the canopy, and gradually climb upward, I will demonstrate it first" Say it, Zhao Xinlong pressed his hands on the canopy, stepped on the crown with the soles of his feet, and easily climbed the paulownia tree. When he reached a height of fifty meters, Zhao Xinlong turned over and came down.

"Do you see clearly," Zhao Xinlong asked.

"Clear," Feng Yu replied.

"Your precise control of Wu Yuan is stronger than that of Xiaoyu and Zhang Ren, just now it is just the first step, the requirement is to balance the release of Wu Yuan of the limbs, control the strength of the limbs, and then tell you the second step to do" Zhao Xinlong came to Tongshu again, this time, Zhao Xinlong gave up his hands, directly used his feet to perpendicular to the canopy, and walked up. Also walking fifty meters high, Zhao Xinlong came to a thicker branch, stood upside down directly, and then turned over.

"Did you see it clearly this time?" asked Zhao Xinlong.

Feng Yu nodded to indicate that he had seen clearly.

"The second step of tree climbing training is to let go of your hands, which is actually much more difficult than the first step, because there is no assistance of both hands, the strength is all concentrated in the feet, the second step is not only to control the strength of the feet, but also to take into account their posture of climbing the tree, the release of Wu Yuan under the feet should be relaxed, especially at the moment of changing feet, the release of Wu Yuan requires precision and speed, as the end of the second step, hanging the golden hook upside down, for the continuous release of Wu Yuan, the size of the release is more demanding, Feng Yu, how, what else do you not understand”

"No," Feng Yu replied.

"Is there any difficulty?" asked Zhao Xinlong.

"No difficulty, thank you Uncle Zhao for your advice," Feng Yu thanked.

"No need" Zhao Xinlong said, "In my eyes, you are my daughter, there is no need to be so polite to Uncle Zhao, and you take so good care of Xiaoyu, it should be Uncle Thank you, girl, you are"

"Uncle Zhao is serious" Feng Yu heard Zhao Siyu and said shyly, "It's all what I should do"

Zhao Xinlong nodded and smiled, and then said, "Tree climbing training is the first step for you to control the precise and fast training of Wu Yuan in your body, you have to practice hard, uncle still has something to do, so go first, if there is any problem, you can come to uncle at any time."

"Thank you, Uncle Zhao" Feng Yu thanked, "Feng Yu must train hard and live up to Uncle Zhao's expectations"

"What a good boy" Zhao Xinlong laughed, and then turned around and left, leaving Feng Yu alone in this tung forest.

Looking at Zhao Xinlong's distant back, Feng Yu was very grateful to Zhao Xinlong for his guidance, and without saying much, he began his own tree climbing training.

Feng Yu came to a huge paulownia tree, looked up, this paulownia tree must also be a hundred years old, the crown is straight, the trunk is thick, and it is nearly 100 meters high at a glance. Feng Yu carefully put his hands on the canopy, slowly transported Wu Yuan in his body in his hands and soles, and climbed up with his limbs, sure enough, things were not as simple as Feng Yu thought at first, if he released too much weight from Wu Yuan, the crown would be left with deep traces, if he released too little, he could not be adsorbed on the canopy, and the most difficult thing was to continue to release Wu Yuan to adsorb, and the more difficult thing was that when the limbs climbed up in coordination, Wu Yuan released the balance of the difficult control, after personally understanding the difficulty of the first step of climbing the tree, Feng Yu had to admit that such basic training was still very necessary, after failing again and again, Feng Yu continued this own tree climbing training。

Feng Yu's training in Tongshulin did not go well, and Zhao Siyu did not move the sea rocks smoothly after getting the four-character secret.

"This Wu Yuan, what does dark energy mean" Zhang Ren complained on the side, "Zhao Siyu, have you thought of it?"

Zhao Siyu shook his head and said he didn't know.

"I don't know what kind of training Feng Yu is doing," Zhang Ren sighed, "I really want to know."

"Let's move the stone in front of you first," Zhao Siyu said, "Father said Yuan Li, Feng Yu reminded Wu Yuan and Dark Jin, presumably it should refer to the Wu Yuan in the body to exert force."

"This is a good idea" Zhang Ren heard it and said happily, "Every time I tire myself to the point that my muscles are sore, when I grit my teeth and exert my strength again, I will feel a trace of strength in my body, do you think it will be Yuan Li, dark energy?"

"You also feel like this?" Zhao Siyu replied, "The body is hollowed out"

"Hmm" Although Zhang Ren was reluctant to share with Zhao Siyu, thinking that Feng Yu was cultivating alone, Zhang Ren also desperately hoped to end his current cultivation and be able to be with Feng Yu. He replied.

"If that's the case, in fact, moving the sea rocks in front of you is not the real purpose of training," Zhao Siyu said thoughtfully.

"What's that?" Zhang Ren stepped forward and asked.

"The real purpose is for us to stimulate the Wu Yuan in our body, presumably my father wants us to use the power of Wu Yuan in our body to move a thousand catties of sea rocks"

"That's true," Zhang Ren replied happily, but in a blink of an eye, he was disappointed, "How can I stimulate the Yuan Force in my body?"

"It stands to reason that only after becoming a martial artist can you smoothly use the Yuan Force in your body," Zhao Siyu said seriously.

"That's what you're talking about," Zhang Ren complained, "The two of us, one is a martial artist of the eighth order, and the other is a martial artist of the third order, and we are still far from becoming a martial artist."

"That's true, but Feng Yu is only a Martial Yuan Ninth Order, but he is already able to use Yuan Force," Zhao Siyu replied.

"Sister Feng Yu is so smart," Zhang Ren said with a smile, "We can't compare."

"Dark energy" Zhao Siyu repeatedly repeated the last word left by Feng Yu, 'dark energy'

The sun at noon is gradually rising, although it is autumn, but such a large martial arts training ground is not able to avoid the cool shade of the sun.

"Have you thought of it" Zhang Ren looked at the silent Zhao Siyu and said, "Let's go eat, it's been morning, I'm hungry too"

"I thought of it," Zhao Siyu said suddenly.

"What did I think of" Zhang Ren was startled by Zhao Siyu's sudden shout.

"I thought of how to stimulate the Yuan Force in my body," Zhao Siyu said happily.

"Let's talk about it," Zhang Ren said happily.

"It's stupid and tiring, but that's the only way to do it for now," Zhao Siyu said.

"Don't sell it, tell me quickly, I'm not afraid of hardship," Zhang Ren said seriously.

"Let's go eat first," Zhao Siyu said with a smile, "Only when you are full, can you start training"

"You should say it quickly," Zhang Ren asked reluctantly behind Zhao Siyu.

"Okay, tell you," Zhao Siyu said, "the limit!"

"Limit?"
