Eight Thousand Four Hundred and Ninety Energy

"How about I try it myself?" Tang Yu was idle, thinking of Xiao Qi's excited look, he couldn't help playing with the jade slip in his hand, and such an idea came into his mind.

"Master, you are a human, even if you have the blood of the witch clan in your body, you are very different from the monsters! Don't you think it's inappropriate for you to practice this technique?" Lianhua Hezhu couldn't help but said when she heard Tang Yu's muttering.

"Anyway, this technique requires demonic energy, and my power of nothingness can transform into any energy. Isn't it equivalent to me also having demonic energy? What's the problem with practicing it?" Tang Yu said calmly.

Tang Yu's explanation made Lianhua Hezhu feel speechless for a moment, but he felt that what Tang Yu said made sense.

"Forget it, Master, if you want to practice, then practice! Anyway, your power of nothingness is really powerful." Lianhua Hezhu muttered, and then he was too lazy to pay attention to Tang Yu.

Tang Yu smiled and was about to start practicing, but suddenly found that there was no demonic energy in his body, so the power of nothingness could not be transformed into demonic energy, so he could only leave the room and walk towards Feng Youqin's home again.

This time, Tang Yu was of course not looking for Feng Youqin, but for Feng Rui.

He wanted to get some demonic energy from Feng Rui in his body, so that the power of nothingness could be transformed, and he would have his own demonic energy, so that he could start practicing the Ancient Temple Beast King Technique.

It was very simple to get demonic energy from Feng Rui. A bag of snacks was exchanged for a lot of demonic energy from him.

Tang Yu used his true energy to wrap up these demonic energy and quickly returned to his residence, and immediately used the power of nothingness to simulate the demonic energy.

Feeling the extra demonic energy in his body, Tang Yu couldn't help showing a faint smile on his face, and then immediately sat cross-legged on the ground and began to practice the Ancient Temple Beast King Technique.

"Om~"

This Ancient Temple Beast King Art is really a very powerful technique. After the demonic energy appeared in Tang Yu's body, this guy thought that Tang Yu was really a demon beast. Tang Yu easily circulated the Ancient Temple Beast King Art in his body for a cycle.

"Peng Chi!"

I don't know if it was an illusion, Tang Yu was shocked to find that he practiced the Ancient Temple Beast King Art much faster than the instructions in the jade slip.

Although as long as you continue to circulate the Ancient Temple Beast King Art according to the cycle, the demonic energy in your body can be continuously enhanced and your strength can be rapidly increased, but after he practiced, the speed at which the demonic energy increased seemed to be too fast.

After a cycle, the demonic energy simulated by Tang Yu with the power of nothingness directly increased tenfold, from the original size of a thumb to the size of an apple. The amount of increase is probably more than ten times!

So Tang Yu circulated it again with a hint of doubt, and then the apple-sized group of demonic energy increased more than ten times again, becoming the size of a volleyball.

When Tang Yu was happily preparing for the third operation, a series of "bang bang bang" knocks on the door suddenly sounded, waking Tang Yu up from his practice.

Fortunately, the practice of the Ancient Temple Beast King Art would not make Tang Yu go astray, otherwise he might get a stitch in the side when he was being interrupted like this during normal practice.

"Who is it!"

Tang Yu was very dissatisfied. He was verifying the effect of the Ancient Temple Beast King Art and was interrupted like this. Naturally, he was in a very unhappy mood.

"Brother, it's me! What are you doing at home? Teacher Qiu Ling asked me to come and ask you, you didn't go to class yesterday, why don't you go today?" Feng Rui's voice sounded outside the door.

"What the hell? I didn't go to class yesterday?" Tang Yu was immediately a little annoyed, thinking secretly in his heart: This stinky woman, she wants to make trouble for me again. Why didn't I go to class yesterday? I just came back from class today. Can you find such a lame excuse?

"Swish, swish, swish!"

Tang Yu rushed to the door in a rage and opened the door at once, with anger in his eyes.

Feng Rui at the door,

Seeing Tang Yu's reaction, was instantly startled, his head shrank, and he said weakly: "Brother, I... I just came to call you according to Teacher Qiu Ling's request! You... Don't be angry with me!"

"Stinky boy, that old woman deliberately made excuses to trouble me, don't you know whether I went to class yesterday and today?" Tang Yu said angrily.

"Brother, you... You really didn't go to class yesterday and today!" Feng Rui was stunned when he heard Tang Yu's words, and then said weakly.

"Let..."

"Master, you have been practicing the Ancient Temple Beast King Jue for two days, and today is the third day!" Tang Yu was about to curse, but the reminder of Lotus Hezhu sounded in his mind, so that Tang Yu swallowed the words on his lips.

"What's the situation? I have only practiced the Ancient Temple Beast King Jue for two cycles, how come more than two days have passed?" Tang Yu stepped aside, motioned Feng Rui to come in, then walked to the chair next to him and sat down, and asked Lotus Hezhu.

"Master, it takes about 28 hours to practice the Ancient Temple Beast King Art once, and 56 hours to practice it twice. How long do you think it has been?" Lianhua Hezhu said.

"So long? How many times has Xiaoqi practiced it so far?" Tang Yu asked subconsciously.

"It seems that one practice has not yet ended!" Lianhua Hezhu said helplessly.

Tang Yu roughly understood what was going on, and immediately looked at Feng Rui, who was standing beside him with an uneasy look on his face, and said directly: "How long does it take for you to practice the Ancient Temple Beast King Art and run one cycle?"

"About ten days!" Feng Rui blurted out.

"Then do you still go to class every day?"

"I have been practicing the Ancient Temple Beast King Art for decades, and I have already reached the point where I can do it at will. Just like now, although I am talking to you, it is still running automatically, but it is slower than when I actively practice." Feng Rui explained.

"Then how much demonic energy can you increase by running one cycle?" Tang Yu thought of the amount of demonic energy he increased by running two cycles, and couldn't help asking again.

"How much demonic energy should I increase?" Feng Rui muttered, then tilted his head and began to think. After a long time, he reluctantly said, "If the number of demonic energy in my body is 100,000 now, then the amount I increase each time may not even reach 1."

"Let me see!" Tang Yu took a deep breath, and his face could no longer hide his smile. He grabbed Feng Rui's arm and probed his mind into Feng Rui's body.

"Boom!"

Suddenly, a huge demonic energy came towards him, and Tang Yu felt like he was hit hard on the shore by a huge wave.

Feng Rui's cultivation is the second star of the ninth level of the middle god. In terms of strength, he may not even be able to match those of the sixth level of the middle god.

His cultivation is only because of the talent of his race. He has a strong cultivation since birth, but that is because of his physical strength. If we really talk about the concentration of demonic energy, Tang Yu estimates that according to Feng Rui, he has 100,000 demonic energy in his body, and Tang Yu has 100 demonic energy in his body.

Tang Yu has only practiced the two ancient temple beast king techniques, and he has reached one thousandth of Feng Rui's level who has practiced the ancient temple beast king techniques for decades. If he continues to practice at this efficiency, wouldn't he only need three more days to reach Feng Rui's level?

If he practices for more days, wouldn't he be able to surpass Feng Youqin soon?

Feng Youqin is a powerful person with the cultivation level of the second realm of true god. Can he really surpass her so quickly? Tang Yu couldn't help but get excited, and the expression on his face began to dance with joy. He blurted out: "I won't go to class these few days. Remember to notify me when you go to compete."
