Su He naturally strongly opposed Sheng Zhuo's decision. Compared with the Sheng brothers who blindly trusted Yan Hao, as a pharmacist, he was more cautious about Yan Hao.

A child who still looks like a student, even if he is a genius, his potion achievement is at best the level of a sixth-level pharmacist. He said the success rate is 60%. Does it really mean it is 60%? Just because he used the values ​​on the mental map to make a calculation?

But all his worries were no match for the persistence of the person involved. After all, no matter how he tried to stop him, as long as Sheng Zhuo took the phantom potion, he would have no choice but to advance. So in the end, Su He also compromised. Instead of opposing Sheng Zhuo to take the phantom potion in private, it would be better for him to watch from the side and help at the critical moment. In case of failure in the advancement, he could also take some remedial measures to prevent Sheng Zhuo's mental strength from falling too much.

"Brother, put your helmet back on." Yan Hao held the detection helmet in front of Sheng Zhuo again.

"What is this for?" Sheng Zhuo was puzzled.

"Although the success rate is 60%, it is not 100% successful. If you wear the helmet, I can observe the changes in your mental power at any time. Once the changes in your mental power exceed a certain range, I will ask the senior to intervene with mental power." Yan Hao said.

Sheng Heng was stunned when he heard this: "I use my mental power to intervene?"

Su He objected after hearing this, "After taking the phantom potion, the user's sea of ​​consciousness will enter an extremely excited state. At this time, mental intervention will be very dangerous for both the user and the intervener."

As the person involved, Sheng Zhuo was the calmest. He asked calmly, "Let Xiaohao finish what he has to say."

Sheng Heng naturally believed Yan Hao, and stopped talking, waiting for Yan Hao to explain. Su He saw this, and a mouthful of blood blocked his chest. He wanted to hear how Yan Hao would explain.

"Generally speaking, after using the phantom potion, the spiritual sea of ​​consciousness will enter a very active state. If external forces invade at this time, it will cause the spiritual power to resist, making the spiritual power too excited, and even disrupt the reorganization of the sea of ​​consciousness. But my brother's situation is different. He wants to advance to S-level." Yan Hao explained in detail, "The S-level spiritual power threshold is infinitely close to the endurance of the sea of ​​consciousness, so even if there is no external force intrusion, when the phantom potion takes effect, the spiritual power will be excited to a degree close to the limit. At this time, even if external forces invade, it will not cause a greater reaction."

Yan Hao turned to Sheng Heng and continued, "Senior is born with S-level mental power. His mental power threshold is naturally higher than those who upgrade their mental power through medicine. That is to say, even if big brother's mental power is successfully upgraded to S-level, the strength of his mental power will still be weaker than that of senior. In this way, senior's mental power can suppress your mental power."

"I understand." Hearing this, Sheng Heng understood, "You want to use the instrument to detect the condition of Big Brother's mental strength. Once you find that the threshold is close to the critical point and Big Brother is in danger of failing to advance, let me use my mental power to invade and forcibly suppress it."

"Well, this can prevent big brother's sea of ​​consciousness from collapsing." Yan Hao said.

As a pharmacist, Su He naturally understood what Sheng Heng could understand, but he found it strange because no one had ever done it before. And it must be said that Yan Hao's plan was more effective than the emergency measures he had just thought of, and it could minimize the consequences of Sheng Zhuo's failure to advance.

Everyone reached a consensus and started to act. Sheng Zhuo put on his helmet, Yan Hao adjusted the instrument, and Sheng Heng sat next to his eldest brother, ready to take action at any time. The only one who had nothing to do was probably Su He. He wanted to help Yan Hao with the inspection, but Yan Hao installed new software on the instrument, and he hadn't learned how to use it yet. He was afraid that he would make things worse, so he could only watch nervously from the sidelines.

"Brother." Everything was ready, and Sheng Heng took out the phantom potion he had placed in the space button.

Sheng Zhuo took it, but did not drink it immediately. Instead, he said to Sheng Heng: "I made this decision by myself. If the result is not good, it has nothing to do with you."

Su He couldn't bear to hear this, and shouted again without giving up: "Major General, why don't you reconsider it?"

Sheng Zhuo ignored Su He and continued to look at Sheng Heng.

"I know." Sheng Heng knew that if it was just him, his elder brother would not say this. They were brothers, and from the moment he chose to give this bottle of medicine to his elder brother, he was ready and determined to bear all the consequences. His elder brother's words were actually reminding him not to blame Yan Hao, fearing that if he failed to advance, it would affect his relationship with Yan Hao.

Sheng Zhuo smiled, and without hesitation, he unscrewed the bottle cap and drank the phantom potion.

The effect of the phantom potion was very fast. Almost at the moment the potion was taken, the numbers on the detection instrument began to jump rapidly. Every change in the numbers represented the violent mental power in Sheng Zhuo's sea of ​​consciousness at that moment.

Gradually, Sheng Zhuo's face turned visibly pale, and he clenched his hands, tightly grasping the bed sheet beneath him. Although he did not make any sound from beginning to end, everyone knew that he was experiencing immense pain.

Finally, the detection instrument seemed to have reached the critical value and began to emit a "beeping" alarm sound. Su He turned around and rushed to the screen of the detection instrument, then looked at the horrifying mental maps on it with a pale face.

"this……"

Just as Su He was about to speak, Yan Hao suddenly sat up straight and shouted in the direction of Sheng Heng: "Senior, get ready."

Sheng Heng has been preparing, just waiting for Yan Hao's order.

"Three, two, one..." As soon as Yan Hao shouted, Sheng Heng's surging mental power forcefully invaded Sheng Zhuo's sea of ​​consciousness.

The "beep, beep, beep" alarm sounded again in a hurry, and each sound was more terrifying than the last. The wavy lines on the mental map were getting higher and higher. The height of the mental power threshold made Su He wonder if Sheng Zhuo's spiritual sea of ​​consciousness was about to burst.

"Okay." As Yan Hao finished speaking, the mental map that had just reached a high point began to fall back to a normal range. At the same time, Sheng Heng also withdrew his mental power and sat there with a tired look on his face.

Forcibly invading a sea of ​​consciousness whose mental power level is close to S-level and extremely violent is also very exhausting for him.

"Senior, get ready." About three minutes later, Sheng Zhuo's mental power threshold jumped again.

Sheng Heng's mental power surged out again.

This was repeated about three times, and Sheng Zhuo's sea of ​​consciousness finally stabilized. However, Sheng Zhuo had fallen into a coma due to prolonged mental stimulation.

"How is it?" Sheng Heng looked up at Yan Hao on the other side of the instrument.

Beside Yan Hao, Su He was staring at the screen in disbelief, as if he was stunned.

"Come and take a look." Yan Hao looked up and waved at Sheng Heng with a smile.

Sheng Heng saw Yan Hao's expression and had a clue in his mind, but he still stood up and walked over to take a look at the screen. On the screen, a complete mental map was displayed, and in the lower right corner of the map, a line of bold golden font was extremely eye-catching.

Mental power level: S level.

There was a long list of analytical data on the mental map below, but Sheng Heng was too lazy to look at it. He only knew that his elder brother's advancement was successful.

Sheng Zhuo was unconscious, so no matter how excited everyone was, they couldn't make loud noises. Finally, Su He, who felt that he had done the least work that night, stayed to take care of Sheng Zhuo, and asked Yan Hao and Sheng Heng to go back and rest first.

Sheng Heng personally sent Yan Hao to the dormitory door.

"Senior, you have overdrawn a lot of your mental energy tonight. Go back and rest early." Yan Hao urged Sheng Heng to go back and rest early.

“Hold me for a while before you leave.” Sheng Heng said, reaching out and holding the person in his arms.

Yan Hao glanced at the door next to him somewhat embarrassedly, and seeing that it was closed, he nestled in Sheng Heng's arms with peace of mind.

"Thank you for your help, big brother." Yan Hao had done so much for him that he didn't know what else to do besides thank you. He thought that this little brother was weak, simple, and in need of protection, but he had been using his own methods to protect himself.

How lucky I am to meet you.

During the time when Master Zhong was modifying the Black Soul, the upgrade of the third-generation system in the base was slowly coming to an end. After that, Master Zhong stayed in the base for another three days, and after answering some difficult questions about the mecha, he prepared to leave.

"Mr. Zhong, I will send a team of soldiers to escort you out." In the center of the port, a careful warship was parked side by side with the mecha that Mr. Zhong and his companions had ridden when they arrived.

"No need, our spaceship has a federal guard." As the head of the Federal Research Institute, Mr. Zhong will naturally have escorts when he travels. The federal guard is specifically used to protect Mr. Zhong.

"The Zerg in the outer domain have been very restless recently, so it's better to be careful. Your safety is related to the future of the Federation." Sheng Zhuo said cautiously.

Seeing that Sheng Zhuo insisted, Mr. Zhong did not refuse. He nodded, said goodbye to Sheng Zhuo, and turned to board the spaceship.

Seeing this, Yan Hao said goodbye to Sheng Heng, then walked up to Sheng Zhuo and warned him, "Brother, your sea of ​​consciousness is still unstable. Try not to use your mental power for half a month."

"A two-year break is not possible, but half a month is fine, don't worry." Sheng Zhuo agreed with a smile.

At this time, Babi Chong called Yan Hao from a distance. Yan Hao did not dare to delay any longer, waved his hand, and boarded the spaceship. Then, the spaceship started and flew into space. Following closely behind was a small warship sent by Sheng Zhuo to protect it.

"My mother called me via video last night and asked me to tell you not to take Xiaohao to see her without her permission." Sheng Zhuo suddenly said.

Sheng Heng was stunned, his face full of confusion: "Why?"

When I told my mother about Xiaohao before, she was very encouraging. Why does she suddenly not want to see him?

"She said she wanted to prepare a gift first." Sheng Zhuo said.

Sheng Heng was still puzzled.

"Mr. Zhong knew about your relationship, so he directly upgraded the Dark Soul system for you. Mr. Pang knew about your relationship, so he directly gave you a pair of particle cannons he made himself. These two things are treasures that cannot be bought with money. Our mother said that she must find a gift of sufficient weight for this trip, otherwise you will not have the confidence to propose to her in the future." Sheng Zhuo couldn't help laughing as he spoke.

Sheng Heng couldn't help laughing either.

"Let's go back to the base." The two of them got on the hovercraft and headed for the base. However, when the car was halfway there, an urgent alarm sounded from Sheng Zhuo's communicator.

"Reporting to the Major General, Elder Zhong's spaceship encountered a Zerg raid. Among the attacking Zerg, there are Level 9 Zergs. The mental shock wave has reached the A-level strength. Mech warriors below A+ cannot approach."

Sheng Heng stood up in a flash.
