Two days passed quickly. Yu Yifeng and more than a hundred high-level government officials and military personnel hurriedly arrived in front of a large instrument measuring ten kilometers in length.

The structure of this big thing is extremely complex and the size is astonishing. In addition to the main body of ten kilometers, it is also connected with the internal nuclear reactor and the Large Hadron Collider. The whole thing adds up to a complete neutrino detection device.

Yu Yifeng finally understood why the bigger the spacecraft became, the more powerful it was, because the instruments and equipment inside were getting bigger and bigger... The space occupied by the instruments was far larger than people's living space.

Theoretically, neutrino detection technology can completely detect the overall situation of the underground. Whether it is one hundred kilometers, one thousand kilometers or ten thousand kilometers, it can basically be seen at a glance like X-rays.

"But there are so many things under the ground. All the images are superimposed and it is not easy to distinguish...many things must be ignored. How about we only look for the thickness of one kilometer on the surface?"

"Okay, let's do this for now."

Ding Yidong and several other experts are confirming the final parameters.

"These Chiyanjiao people have special scales on their bodies, and the scales contain metal elements, so we specially debugged certain frequency bands to focus on detecting these scales."

"Ordinary organic matter is actually very difficult to detect..."

Yu Yifeng is watching the detailed instructions of this device.

Due to power constraints, this device cannot detect the entire planet at once, but can only explore it part by part.

"The neutrino beam is the decay product of secondary particles. It cannot be produced by direct targeting of the primary beam. In order to increase its intensity, special focusing equipment is required."

As for this neutrino detection device, a large number of neutrinos are collected from the nuclear reactor and then emitted to the rated area like a radar.

"Let's get started." Yu Yifeng couldn't wait to say after seeing the debugging work completed.

With today's instruments, the amount of engineering work is getting larger and larger. It can no longer be completed by one scientist overnight. The huge hadron collider has turned into a single component. This highly complex thing took more than ten years to complete.

The effort is not excessive.
