Xia Heqing didn't want to recruit volunteers to test the chair, because he carefully studied the formulation of the chair and found that his initial guess was correct, many of the instruments on the chair could be pulled out, and they were all for medical purposes.

Since it's a medical chair, why does it have a space-time teleportation function? This made Xia Heqing very puzzled, although he did not understand the technology three hundred years later, but he understood that the function of any kind of instrument will have the main function and additional functions.

And no matter what the design philosophy is, it will not let the additional features outweigh the main ones.

According to this line of thinking, if this instrument is a treatment chair, it will not come with a space-time teleportation function.

And these two functions are incompatible, Xia and Qing can't figure it out, why would the designer put these two energy supplies together?

These thoughts were hidden in his heart, and Zhou Qingyu only knew that his father-in-law was in deep thought, and he needed to remind him to even eat and sleep.

Zhou Qingyu finally couldn't help it, "Father-in-law, do you need to recruit volunteers for testing?" ”

"No, you don't." Xia Heqing replied.

"Why?" Zhou Qingyu was puzzled, didn't the space-time machine recruit a lot of volunteers for testing?

"This device is different from the space-time machine, first of all, it does not have intelligent operation equipment, I suspect it is just a one-way channel!" Xia Heqing explained.

"What is a one-way channel?" Zhou Qingyu asked humbly.

"You can only teleport to another time and space, and you can't come back through this channel!" Xia Heqing shook his head, feeling that his son-in-law's IQ was not high.

Zhou Qingyu didn't know that he was disgusted by Xia Heqing, and he was still thinking, no wonder Xia Heqing didn't agree to carry out live experiments, there was such a deal that would go and go back, even volunteers would not agree to participate.

"Moreover, there is another reason why I am not allowed to use this therapeutic chair to carry out experiments, that is, for this kind of experiment that cannot be controlled, it is better not to rush it now, so as not to alarm that mysterious force."

This time, Zhou Qingyu didn't ask any more questions, but sat next to him with some frustration, he was thinking, when will he see Su Keke?

Fortunately, Zuo Lang was teleported, and this incident also indirectly reminded Admiral Qi that when he chose the candidate to be stationed in the laboratory, he took loyalty and reliability as the main requirement to avoid accidents like Zuo Lang again.

Zo Lang's next successor was an officer transferred from the ground forces to the Special Operations Division, a man who did not spearhead a major operation or travel abroad to carry out missions.

But everyone who has worked with him thinks that this is a person with a strong sense of teamwork, and they can rest assured that they can hand over their backs to him.

This person's name is Mu Zhijun, and he is an ordinary-looking young man, who is plain and silent, and only when he can't figure out the content of the task, he will ask questions repeatedly.

Zhou Qingyu still didn't dare to directly hand over the work to him, but stayed in the laboratory, worked with Mu Zhijun for a few days, and after confirming that the other party could do the job, he went home to rest with confidence, and as of today, he has not gone home for eight days.

Before going home, Zhou Qingyu called Su Keke and made it clear that she was at school, so he drove all the way away.

What Zhou Qingyu didn't expect was that every time he was waiting for Su Keke, and this time, as soon as his car drove to the school gate, he saw Su Keke standing at the school gate and looking around, obviously waiting for him!
