After listening to long Tianci's explanation, Chu Yunfeng's muscles beat a few times. Then he looked at long Tianci with an extremely strange expression and asked, "master, what kind of oxygen and hydrogen do you say? Why haven't I heard of it before?"

Long Tianci was stunned by Chu Yunfeng's problems. Then long Tianci began to secretly scold himself as an idiot. He didn't study these knowledge in the world. If he hadn't met Mu Wenfeng and tassels, he couldn't understand these. Now he and a 13-year-old child say these problems as if they were telling him heavenly books, How can the child understand?

After awkwardly pondering for a while, long Tianci scratched his head and said, "forget it! It's normal for you not to understand now. In the future, I will teach you these knowledge in addition to teaching you martial arts and the use of element energy. Then you will understand it slowly!"

"Oh ~!" Chu Yunfeng agreed, and then nodded. However, it can be seen from this guy's face that his heart is full of doubts, but it's normal. Children of his age have a strong desire for knowledge of unknown things.

For the next period of time, long Tianci asked Chu Yunfeng to try to combine spiritual power with elemental energy and control elemental energy through spiritual power. Perhaps it is because Chu Yunfeng first contacted elemental energy of water attribute, so after trying for half an hour, Chu Yunfeng can simply control the energy of water attribute, but Chu Yunfeng has made no progress in fire attribute, According to Chu Yunfeng, although he can feel the energy of fire attribute elements, he can't control it. Every time he wants to control, fire attribute elements are as difficult to tame as runaway wild horses!

Soon the day passed again. When he came home at night, Chu Yunfeng was very excited and showed off with the five fish he caught and Meiya. Meiya was very happy to see her son's achievement. She even kissed her son for a long time and boasted that her son was promising!

After dinner, long Tianci didn't go back to rest, but left after saying hello to Meiya. He didn't come back all night!

The next morning, Chu Yunfeng found that long Tianci was not there, so he went fishing by the lake first. According to long Tianci's requirements, Chu Yunfeng's fishing task from that day on was to catch five fish of the same species. It was simple, but it was actually very difficult. Chu Yunfeng caught 12 fish of the same species all day, and only three of the same species, This made Chu Yunfeng depressed. However, it was already dark. Chu Yunfeng was afraid of Meiya, so he didn't insist on going home directly!

Chu Yunfeng, who returned home, found that long Tianci was not there as soon as he entered the house. This is not normal. In theory, long Tianci will always accompany him. Chu Yunfeng was curious that he didn't go to the lake today. Long Tianci, who went out last night, hasn't come back yet. Obviously, it's not normal!

At the request of Meiya, Chu Yunfeng went out to look for long Tianci without even having dinner, but he found no trace of long Tianci in the middle of the night. He had to go home reluctantly. When he wanted to come to long Tianci, he might have been tired of teaching himself, so he left quietly!

Although long Tianci is gone, Chu Yunfeng continues to practice according to long Tianci's instructions every day. Before dawn every morning, Chu Yunfeng carries a fishing rod to go fishing by the lake. When the sun goes West, he will come back and start again. In a flash, nine days have passed!

In these nine days, Chu Yunfeng can only catch three of the same fish from the first day to the last morning. His progress can be called great speed. Through this training, Chu Yunfeng has made a qualitative leap in his control of mental power. Now Chu Yunfeng can control his emotions without difficulty. Chu Yunfeng can easily control his joys, sorrows and joys!

In addition to the improvement of mental strength, Chu Yunfeng's control of element energy has also been greatly improved. It may be because he has a strong affinity for water, so Chu Yunfeng can skillfully control water on the third day after long Tianci left. However, Chu Yunfeng has no clue about the control of fire, let alone control, He can't even make a simple connection!

From the fourth day, Chu Yunfeng's element control training after fishing every day completely focused on the flame attribute. In order to feel the flame, Chu Yunfeng even lit a campfire and put his hands in it to feel the power of the flame!

With the contact and understanding of the energy of the flame element, Chu Yunfeng finally found the reason why he could not control the energy of the fire attribute element. That is, his mental power wavelength is not suitable for controlling the flame. Unlike the tranquility and ease of water, the flame is violent and restless. Chu Yunfeng's calm attitude before fishing makes his mental power unusually quiet, Therefore, it is very simple to synchronize with the wavelength of water elements, but it is not so simple to use this peaceful spiritual force to control fire elements.

Realizing that Chu Yunfeng finally fully understood the intention of long Tianci to let him fish, long Tianci obviously not only wanted Chu Yunfeng to use fishing to cultivate his self-cultivation, but also hoped that Chu Yunfeng could freely control his emotions and reach the point of flowing in the transformation of emotions.

Tentatively, Chu Yunfeng began to control his emotions to change in the direction of rage and excitement. With the change of Chu Yunfeng's emotions, the mental power released by Chu Yunfeng also changed. With the change of mental power, the fire attribute elements that have been unable to be fully integrated finally successfully integrated into Chu Yunfeng's body.

On the afternoon of the ninth day when long Tianci disappeared, Chu Yunfeng stood up after completing his fishing practice, then went to the prepared firewood and lit the campfire with a fire fold. Then Chu Yunfeng sat cross legged in front of the fire and put his hand into the fire. Although Chu Yunfeng's hand went into the fire, the fire magically did no harm to Chu Yunfeng's hand, All the flames just surrounded Chu Yunfeng's hands and did not ignite his hands!

Put his hand in the flame and feel the energy fluctuation of the fire attribute element. Chu Yunfeng gradually released his mental power and combined with the energy wavelength of the fire attribute element. About ten minutes later, Chu Yunfeng suddenly waved his hands upward. With his action, the flame on the fire was controlled and elongated by Chu Yunfeng, and then the flame was completely separated from the firewood, And turned into a fireball and stayed on Chu Yunfeng's hands.

Chu Yunfeng slowly opened his eyes, and then looked excitedly at the fireball in his hand. For nine days, after fifty failures, Chu Yunfeng could finally successfully control the flame element! This is definitely a leap for him.

Just when Chu Yunfeng was excited, the fireball on his hand suddenly shook violently, and then the fireball disappeared, which stunned Chu Yunfeng who was still excited. Then he stared at his hands and began to Daze!
