The mysterious Xu Guohua settled in the Ninth Army. He contacted Zhou Qingyu and gave him a letter, which is said to have been written by Zhou Qingyu himself. Writing a letter to yourself takes advantage of the causality of time and space.

Zhou Qingyu couldn't understand the middle channel, so he simply didn't think about it, so according to Xu Guohua's request, he chose a place to build a laboratory in the military headquarters of the Ninth Army.

Not only is it quiet but also very safe, the surrounding residents have no curiosity, Zhou Qingyu personally feels that there is no place more suitable for this kind of experiment than the military headquarters of the Ninth Army.

Xu Guohua was not very picky, and before the completion of the new laboratory, he borrowed the warehouse of the Ninth Army and started scientific research.

Xu Guohua's team is not many, except for himself, there is only a big man with a full beard, this big man seems to imitate Lu Zhishen's style, shaved his hair well, but has a large beard, Xu Guohua called him Luneng.

Xu Guohua and Lu Neng brought in some things, and for the safety of the Ninth Army, all these things were tested. Then, Xu Guohua and Luneng began to build machines in the empty warehouse.

Zhou Qingyu, as a landlord, was allowed to visit the site, and he found that this space-time machine, from the appearance, looks like a huge mechanical door frame, a track, and a number of large and small display screens.

"Professor Xu, didn't you say that the space-time machine is still under development?" Zhou Qingyu pointed to the mechanical door, "What is this?" It seems to be ready to run! ”

"You've got a good eye! I'll not hide from you, the machine itself is simple, but the energy to drive it is hard to find! Xu Guohua lowered his voice, "Do you know why I cooperate with the people of country E?" It's because there is a kind of precious mineral deposit, which only exists near the Arctic Circle of country E! ”

Zhou Qingyu felt a little headache: "Wait, you won't still have to mine, right?" ”

"Of course!" Xu Guohua looked like he took it for granted, he pointed to the empty track, and was a little emotional, "Otherwise, what do you think the space-time machine relies on?" ”

Zhou Qingyu hugged his arms and carefully examined this so-called space-time device, he was suddenly a little confused, should he believe this Xu Guohua!

As if to see Zhou Qingyu's worries, Xu Guohua smiled generously: "It is still in the stage of trial operation, and this conveyor belt and the space door cannot be used," he pointed to the circle of display screens, "The image is already available for viewing, are you interested?" ”

Zhou Qingyu understands that what Xu Guohua said about you is not only referring to himself, but also to the speaker Long Zhanlong behind him who supports this research.

He made a special report on this matter to Speaker Long, and Speaker Long really brought a few henchmen to visit, of which the military accounted for two people, namely General Qi and Gu Yao.

According to Xu Guohua, activating a space-time device consumes a huge amount of energy, which is one of the reasons why he does not use this technology exclusively, but cooperates with the government.

Now the display screen is going to run, and it consumes only ordinary electricity, Xu Guohua connected the time machine into the power system of the magic capital, he explained this situation, the moment it is turned on, it will consume the power of the entire city.

In order to see the effect of the display screen, Speaker Long set the time to turn on the machine in the early morning, during this time period, the residents are resting, and the power failure will not cause much impact.

Everything was ready, and Xu Guohua said solemnly: "The display screen can work for three periods, each period is no more than five minutes, and you can freely choose the past or future time to watch!" ”
