In 2027, a base in the north.

In a test hall of thousands of square meters, dozens of people are working nervously, except for the subtle sound of the machine fan, there is no other noise.

Zheng Zhi stood in the center of the hall, looking around at all the workbenches with his hands behind his back, with a serious expression.

"Mr. Zheng, can you start?" The assistant asked.

"Let's get started." Zheng Zhishu replied categorically.

At the sound of a command, all the screens in the laboratory flashed, the keyboard and mouse clicked together, and the huge antennas outside the base began to slowly rotate, extending their tentacles into space.

This is the latest high-precision radar system developed by Zheng Zhi and other experts of the institute with the efforts of the institute for more than three years, and what they are doing now is the last test item of the radar system before it is finalized.

"Low-altitude target lock!"

"Medium-range stealth target lock!"

"600 kilometers of high-speed target locking!"

With a crisp report, a shallow smile appeared on Zheng Zhi's face, everything is normal, and a new national weapon is about to be finalized.

"Mr. Zheng, ultra-long-range target measurement found abnormality!"

A discordant voice rang out. Zheng Zhi's heart sank, and a few arrows rushed to the side of the experimenter who gave the warning. I saw that on the big screen in front of the experimenter, a signal that had never appeared before appeared, the radar control instrument automatically monitored and positioned, and displayed it on the high-resolution military screen display at the same time in the form of coordinate diagram and real-time signal parameters, and the original three-dimensional coordinates of the earth's spherical surface were automatically switched to the mode of interstellar three-dimensional coordinates......

"This is a signal from the γ planet of Centauri! Oh no, the signal resonated with our test signal! Zheng Zhi exclaimed.

At this moment, the parameters of the signal suddenly changed drastically, and the sound coming from the military planar loudspeaker after the signal was converted by analog suddenly became extremely sharp and weird. Zheng Zhi felt his heart beat faster, his whole body went limp, and he lost consciousness in an instant.
