"How can you talk to your master like that?" Chen qianer was surprised to see Wang Tianyu yelling at Chen Yu. Chen qianer, who is usually more rational, shouted at Wang Tianyu at this time in order to protect Chen Yu.

"Then why did Chen Yu say that about me? Was it really a mistake for me to stay in Shenyun auction house? Was it not Chen Yu who let me learn and control black gas? Why now, I have to recite and resist all things by myself." Wang Tianyu immediately hit back at Chen qianer, and immediately released his pent up anger, A faint black air slowly rose from Wang Tianyu's body.

"Wang Tianyu, what are you going to do?" Chen Yu saw a trace of light black gas on Wang Tianyu's body. Chen Yu realized that it was bad. At this time, Wang Tianyu had been blinded by heart demons and lost his reason. With this strength, black gas began to burst out wantonly from Wang Tianyu's body.

"What am I going to do? I'd better ask yourself." Wang Tianyu smiled and said fiercely to Chen Yu.

At this time, Wang Tianyu has completely lost the feeling of the past. Now Chen Yu can feel only Wang Tianyu's hatred for himself.

"What's going on, Chen Yu?" Chen qianer looked at Chen Yu and asked. Wang Tianyu in front of her had lost his old image. Her two eyes revealed a fierce light, as if she wanted to kill someone at any time.

"Wang Tianyu should have been disturbed by the black gas in his body. Now Wang Tianyu is not the same as before." Chen Yu looked at Wang Tianyu warily and explained to Chen qianer.

"Can the power of this black gas become so strong? Can a good person be disturbed by anger in an instant?" Chen qianer obviously didn't believe in the power of this black gas, so she then asked Chen Yu.

"Well, at the beginning, I was still struggling to let Wang Tianyu practice black Qi, but the mark on Wang Tianyu's arm has slowly begun to spread. If I still don't use the breath in my body to talk about the suppression of Wang Tianyu's mark, I may be alone this time." Chen Yu said to Chen qianer.

"Don't be hypocritical. You are jealous that I am better than you. You are jealous that I can practice black Qi and envy my talent in a few days." Wang Tianyu seemed to have changed into a person, and then smiled evil.

"Not good." Chen Yu quickly pushed away Chen qianer around him, and a real Qi quickly arose in his palm, which resisted the black Qi of Wang Tianyu attacking himself.

"Wang Tianyu, how can you beat your master!" Chen qianer shouted at Wang Tianyu.

"Master? I don't have a master at all. I was inadvertently taught by a kind man. What about Chen Yu? What did he teach me?" Wang Tianyu opened two black eyes without white eyes angrily and stared at Chen qianer.

"Brother Chen Yu, his eyes." Chen qianer saw Wang Tianyu's two eyes without white eyes, so she said to Chen Yu in disbelief.

"Now Wang Tianyu has been demonized and completely disturbed by black gas. He is no longer my former apprentice." Chen Yu looked at the irrational Wang Tianyu in front of him.

Chu ling'er heard the quarrel in the room, so he quickly opened the door and went in.

Chu ling'er saw Wang Tianyu whose two eyes became black, and couldn't help but step back.

"What's the matter with Wang Tianyu?" Chu linger shouted at Chen Yu. In front of him, Wang Tianyu with black eyes and black body really scared Chu linger, so Chu linger asked Chen Yu.

"Ling'er, be careful, he is not the original Wang Tianyu. Now Wang Tianyu has been disturbed by black Qi." Chen Yu explained to Chu ling'er again.

"Just in time, I'll take this opportunity to kill all of you!" Wang Tianyu clenched his fist, and the black air around him became more and more, quickly turning the originally bright room into a dead hell like room without any sunshine.

Wang Tianyu clenched his fists, and the black gas quickly concentrated on Wang Tianyu's fist. Then the soles of his feet sank, and the bricks and tiles in the room began to shake because of this slight sinking.

"What's the matter with Wang Tianyu?" Chu linger asked Chen Yu. Obviously, he still didn't know what happened to Wang Tianyu.

"It's a long story. Wait a minute." Chen Yu didn't have time to deal with Chu linger's problem. He just stared at Wang Tianyu's every move carefully for fear that Wang Tianyu would attack him quickly, but he didn't have any defense.

"Wait a minute? Wait a minute, I'm afraid you won't have a chance." Wang Tianyu said fiercely to Chen Yu.

The soles of Wang Tianyu's feet sank and flew towards Chen Yu.

Chen Yu clenched his fists, and two true Qi came from Chen Yu's fists.

"Take it." Wang Tianyu punched Chen Yu hard.

One black and one white, a similar situation, kept rolling in Chen Yu's mind. He remembered the duel between him and Liang Yunfei.

The room became bright and dark, and the two gases collided constantly. A few seconds later, the room began to become bright, and Wang Tianyu disappeared.

"Where's Wang Tianyu?" Chen qianer saw that the room became bright, but she didn't find Wang Tianyu's figure. Only Chen Yu was left, covering his chest and a touch of bright red around his mouth.

"I should have run away. I didn't try my best this time. I'm worried that if I concentrate all my true Qi on my hands, Wang Tianyu's life may not be covered." Chen Yu reluctantly wiped the blood from the corners of his mouth and said to Chen qianer.

"How could Wang Tianyu become like this?" Chu linger asked Chen Yu.

"It's all my fault. I let Wang Tianyu practice this black Qi, so Wang Tianyu will become what he is today." Chen Yu sighed helplessly and said to Chu linger.

"Brother Chen Yu, why did you let Wang Tianyu practice black Qi?" Chu ling'er asked in some confusion.

"If you don't practice black Qi, Wang Tianyu's life will be consumed by the black Qi." Chen qianer looked at Chen Yu panting heavily, so she answered for Chen Yu.

"Forget it, let's heal brother Chen Yu first." Chu ling'er didn't plan to ask, and began to care about Chen Yu's injury.

Chen Yu returns to his house. Chu ling'er also returns to Chen Yu's room with Chen Yu. Seeing that she has no ability to help Chen Yu, Chen qian'er returns to the mansion of Shenyun auction house and asks the two soldiers outside the mansion to strengthen the guard.

Chu ling'er took off Chen Yu's coat and looked at Chen Yu's wound carefully.

"Brother Chen Yu, the black gas is really unusual. Look at the place where you are injured. Unlike other wounds, your wounds have been blackened by the black gas. I don't think I have the ability to help you treat this. I can only help you temporarily alleviate your wounds." Chu ling'er said reluctantly.

"OK, let's relax for a while. By the way, can Chen qianer ask some people to let yuan Xiwen come over?" Chen Yu said to Chu linger.

"OK, brother Chen Yu, I'll ask sister qian'er to send someone to find yuan Xiwen after I relieve you." Chu ling'er replied.

Chu ling'er's hands slowly appeared two faint true Qi, and some cold hands slowly pasted on Chen Yu's injured position.

Chen Yu was surprised to see Chu ling'er's progress. He didn't expect that Chu ling'er could heal people with true Qi after only a month.

"Chu ling'er, you have made great progress." Chen Yu smiled and said to Chu ling'er.

"It's just some fur. Yuan Xiwen gave it to me. If he didn't have something, I could learn more." Chu linger heard Chen Yu praise himself, so he responded modestly.

"Yes, you must study hard with brother Xiwen in the future and strive to be a great man like your master." Chen Yu encouraged Chu linger.

"Well, I will."
