The team soon returned to the camp. The forklift in the camp has been prepared. Professor Xu in the base arranged seven or eight kinds of energy detection machines on both sides of the whole conveyor gate.

After these instruments began to operate, a forklift immediately forked an iron cage and walked directly into the conveyor door. When the iron cage forked by the forklift, that is, the red crazy wolf, passed through the conveyor door, the visible range of the whole conveyor door increased a little.

Not only Professor Xu and them, but also Jiang Yanhai opened the advanced scanning program nearby. Even the advanced scanning program did not find any abnormality. Anyway, when the red crazy wolf was sent to the other side, the whole portal expanded a little without warning.

There seems to be no connection between the two.

The research still needs to be studied. When Professor Xu and his colleagues checked all the instruments and found nothing, they had to let the staff continue.

Soon, the nine red crazy wolves were forked to the base, and the portal expanded one circle, leaving the last one. Professor Xu didn't let them do it, but prepared to dissect and test it directly here.

These jobs are not what Jiang Yanhai needs to worry about. In fact, if even advanced scanning programs can't find abnormalities, these modern instruments probably can't find abnormalities.

On the contrary, the UAV in the air is constantly shooting terrain pictures around, and then constantly expanding the shooting range. The pterosaur has a limited ceiling, and the maximum ceiling is about 8000 meters. According to the photos with a resolution of 6 meters, it can shoot a radius of about 15 kilometers.

According to the maximum operating distance of 20km, it can shoot all terrain within a radius of 35km. Nearly 3900 square kilometers of land area.

"According to the report, there is also a small town about 28 kilometers to the East, which seems to be larger than the area we have found so far." the UAV operator here finally made a new discovery.

"Didn't you find anything else?" Jiang Yanhai looked at him and asked.

"Report, No."

"Send a team to set out, build a temporary relay signal tower and increase reconnaissance in the area." Jiang Yanhai thought for a while, and then issued the latest instruction.

"Yes!"

With Jiang Yanhai's order, a special combat team, together with two SM assault vehicles and two trucks loaded with simple signal towers, quickly moved forward to the area.

Between the base and the town, there is a not high mountain, which can just build a simple signal relay tower.

However, because this signal tower adopts solar power supply and battery template, and is a simple signal tower, it can increase the signal transmission distance of about 15 kilometers at most.

Drones can't fly far, but monitoring the town and its surroundings should be enough.

The speed of the signal tower team was very fast, and the construction task was completed in less than 3 hours. When the construction task was completed, the pterosaur began circling and reconnaissance at the high altitude of the town.

It doesn't need to descend. Even in the daytime, people on the ground can't find the existence of UAV at all. When sending this team out, Jiang Yanhai sent three teams to escort Professor Xu and their six scientists to the town that was slaughtered.

The purpose of escorting these scientists in the past is to check and search the whole town to see if they can get some useful information, such as books. Through these aspects, we can understand the situation here. At present, Jiang Yanhai's eyes are black, and most of the speculation comes from Dai Yao and the man he caught before.

But that man is not as literate as Dai Yao. The words in the mouth of these illiterate ordinary people are more rumors similar to feudal superstition, and many of them can't be taken seriously.

Professor Xu sent them out. Five hours later, they returned. They really found a lot of books in this town.

However, there is not much useful content found in these books.

"According to the information we have collected so far, this country calls itself Xia Yan people and Xia Yan country, because in ancient times they thought they originated from two primitive tribes called Xia Heyan."

"Their last feudal dynasty, called the Daqin Empire, has existed for about 700 years, and Daqin fought with these infected monsters for nearly 300 years. According to our estimation, this feudal dynasty should exist for so many years under the oppression of this external force."

"At present, according to the information collected and corroborated in these books, Daqin completely collapsed about 80 years ago, because the number of red and crazy wolves suddenly increased, broke through Daqin's defense line and entered its hinterland. All parts of Daqin fought their own battles. Soon, it died in name."

"Before the collapse of the Qin Dynasty, they had developed gunpowder guns. According to the final technology, it was probably equivalent to the level of Mauser 1888 rifles. Later, because of the collapse of the whole dynasty, the basic rifle technology was maintained at this level."

After studying these books carefully, Professor Xu gave Jiang Yanhai a speculative answer.

This answer is conducive to Jiang Yanhai's understanding of the scientific and technological level and part of the history of the world. In fact, it doesn't play much role.

"Professor Xu, please report this news. Next, we may have to establish a safe defense line before you can carry out complete research." Jiang Yanhai thought and said seriously.

He is the top commander here, so how to study, Professor Xu, they also want to communicate with Jiang Yanhai.

"I see."

In the next few days, Jiang Yanhai sent several different combat teams to catch these red crazy wolves, and the red crazy wolves they caught were used as the portal behind them.

The larger the diameter of the portal means that they transmit more materials. Unfortunately, it is located inside the secret base and in the hinterland of the mountain. If it is in the plain, it is estimated that it can transmit more things.

A week after entering the portal, Jiang Yanhai's base began to take shape. In the next step, they are going to take down the nearby town first, which will be used to communicate with these local residents in the future.

The portal will not be seen by anyone except Dai Yuan and the man released by Jiang Yanhai.

But before Jiang Yanhai could make the next plan, he received an urgent message from the temporary headquarters.

"Report! Commander, we found that a large number of red crazy wolves gathered. They rushed from more south. At present, there are at least thousands. Their goal is the No. 2 town found in the East."

"Prepare for rescue!" Jiang Yanhai made a decision without hesitation!
