There was another silence, and the three of them seemed to be thinking about some of the past events of the soldering iron head.

"Liu Fei, in fact, I have long been tempted to retire. Some of my sons have left the planet Zoer long ago, and Kasso will leave with me. I have no regrets about leaving this time, only you..."

"Don't worry, Uncle Jiu, I will take care of myself."

"Well, just be able to take care of yourself. Uncle Jiu knows that you have always wanted to have your own mecha. There are two space buttons here, and there are two mechas inside. Just treat it as Uncle Jiu's gift to you..." Brother Jiu said as he took out two black rings, which flashed intoxicating light under the bright light.

"Thank you." Looking at the two black rings, Liu Fei's heart beat wildly, but he still shook his head firmly.

"It's true that he has the same stubborn temper as a soldering iron head. These two mechas are also your spoils." Brother Jiu shook his head and sighed.

"Trophy?" Liu Fei's eyes lit up and he immediately thought of two brothers assassins.

"Yes, the spoils." Brother Jiu smiled and said, "The two killers are very good at it, but they were born at the wrong time. When they met their son with iron heads, they took the handful and returned it to their original owner."

"Thank you, Brother Jiu." Liu Fei did not refuse anymore. As Brother Jiu said, this should be something that belonged to him, and there was no psychological barrier for Liu Fei.

"Okay, you guys talk. Brother Jiu is gone. Haha, I am very happy to see my son with the iron head grow so big!" Brother Jiu stood up, patted Liu Fei on the shoulder, and left with a laugh.

"Liu Fei, I found the secret of the stalking arc step." After Brother Jiu left, Kaso said immediately.

"Really?" Liu Fei, who was touching the mecha button, was extremely excited. After hearing Kasso's words, he was even more excited.

"Well, strictly speaking, the skeleton arc step is not a real fighting step, but a virtual action of the brain to stimulate the nervous system to stimulate the secretions of the potential power of the human body, make the brain's thinking clearer, and put the body in a peak state..." Casso's eyes ejected the light of wisdom.

"It's not the pace...but...I'm obviously learning pace." Liu Fei said in confusion.

"Well, you can be sure that it is not the pace. The pace you see is just a natural manifestation after stimulating potential, not a fixed and regular fighting technique. Moreover, this brain simulation stimulates potential will cause serious damage to the body. The reason why you can stimulate potential from the pace is a reverse effect."

"How did that black fighter mech do it?"

"You have a misunderstanding, that is not the mecha, but the human brain. In fact, when a person makes a mecha, he will first think of anthropomorphism and try to be similar to the human body movements... Not to mention this, I don't know much about mecha, but I will also talk about the solution to the skeleton arc step. It is the same as last time. There are only two solutions. The first is to maintain the losses spent by the brain and body after stimulating potential through drugs, and the second is to make the body strong enough to counter the side effects caused by stimulating potential."

"Do you have the medicine?" Liu Fei couldn't help but feel a little disappointed.

"No, this drug must be very confidential and cannot be obtained by ordinary people. Moreover, it will take only one or two days to study it. This requires extremely strong funds and scientific and technological strength as a backing, and there must be a very large experimental group. Therefore, the feasibility of obtaining the secret recipe for drugs is very low. Besides, even if there is one, I don't want you to use it. Generally speaking, irritating drugs will cause great harm to the human body."

"Then what else can I do?"

"Through scientific training, make the body structure and body stronger, and then you can use the bracketed arc steps at will."

"I don't want to be exhausted after practicing once." Liu Fei couldn't help but smile bitterly. He didn't want to try the feeling that life was worse than death, especially after that, he was so weak that he could not protect himself. It was too dangerous.

Learning a skill is to better protect yourself. If you lose your life to learn this skill, there will undoubtedly be no meaning in the existence of this skill.

"Don't worry, I have set up a training course for you. At present, I divide the training into seven levels, which means that the maximum value after human explosion potential is seven times. However, this training course still needs to be improved slowly by yourself..."

Kasso took out several stacks of paper the size of nails from his body and put them on a metal round table.

"What's this?"

"This is a precision test strip, which mainly tests the concentration percentage of the substances contained in the human body. You must use the test strip to test the blood every time you reach the highest risk value. Some chemical substances in the blood test strips to test accurate data. Later, when you train, use the data of the test strips as the basis, and then define a training intensity. When your body is enough to compete with the first stage, you can enter the second stage..."

After Kasso's careful explanation, Liu Fei kept touching the ring in his hand, and remembering those complex and profound test methods.

"Okay, look at the absent-minded look. Let's stop here today. I won't let you leave. I'm afraid you'll be summoning me to kill me, the immortal."

“…”

Liu Fei suddenly looked embarrassed and hid his ring in his palm.

"Go."

"Then I'll go."

Seeing Liu Fei gust of wind blowing out, a hint of love appeared on Kaso's face.
