The convoy soon returned to the vicinity of the camp, the forklift in the camp had been prepared, and Professor Xu in the base had arranged seven or eight kinds of energy-detecting machines on both sides of the entire portal.

After these instruments began to operate, a forklift immediately forked an iron cage and walked directly into the portal, when the iron cage forked by the forklift, that is, the red mad wolf, passed through the portal, the entire portal expanded a little with the naked eye.

Not only Professor Xu and them, Jiang Yanhai was opening the advanced scanning program next to him, and even the advanced scanning program did not find any abnormality, anyway, when the red mad wolf was sent to the other side, the entire portal directly expanded a little bit without warning.

There also seems to be little connection between the two.

The research still has to be studied, and when Professor Xu and the others have checked all the instruments and found nothing, they can only let the staff continue.

Soon, the 9 red mad wolves were forked to the base, and the portal was also enlarged, and there was still the last one left, Professor Xu and they did not let it go, but prepared to dissect and test it directly here.

These tasks are not for Jiang Yanhai and them to worry about, in fact, if even advanced scanning programs can't find anomalies, there is a high probability that these modern instruments will not be able to find anomalies.

On the contrary, the drone in the air is constantly circumnavigating to take pictures of the terrain, and then constantly expanding the range of shooting, this pterosaur has a limited ceiling, the maximum ceiling is about 8000 meters in the sky, according to the 6-meter resolution of the photo, it can shoot a radius of about 15 kilometers.

Based on the calculation of the maximum operating distance of 20 km, it can shoot all terrain within a radius of 35 km. Nearly 3,900 square kilometers of land area.

"Reportedly, about 28 kilometers or so to the east of us, there is also a small town that seems to be larger than the one we have found so far." The drone operator here has finally made a new discovery.

"Nothing else has been found?" Jiang Yanhai looked at him and asked.

"Report, no."

"Send a team to set up a temporary relay tower and increase reconnaissance of the area." Jiang Yanhai pondered for a moment, and then gave the latest order.

"Yes!"

With Jiang Yanhai's order, a special operations team, with two Bobcat assault vehicles and two trucks loaded with improvised signal towers, quickly advanced towards the area.

Between the base and the town, there is a not-so-tall mountain that is just big enough to build a simple signal relay tower.

However, because this kind of signal tower uses solar power and battery templates, and it is a simple signal tower, it can increase the signal transmission distance by about 15 kilometers at most.

The drone won't be able to fly far, but it should be enough to monitor the town and its surroundings.

The signal tower team was very fast, and it took less than 3 hours to complete the construction task, and when the construction task was completed, the pterosaurs began to hover and reconnoiter the high altitude of the town.

It doesn't need to descend in height, and even if it's daytime, people on the ground won't be able to detect the presence of the drone at all. When this team was sent out, Jiang Yanhai sent three more teams to escort Professor Xu and his six scientists to the slaughtered town.

Escorting these scientists over is to check and search the entire town, to see if they can get some useful information, such as books, through these aspects, you can understand the situation here, at present, Jiang Yanhai and they are all blinded, and most of the speculation comes from Dai Yao and the man who was caught before.

But that man is not as educated as Dai Yao, the words in the mouths of these illiterate ordinary people are more rumors similar to feudal superstition, and many of them cannot be taken seriously.

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

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

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

"And their last feudal dynasty is called the Great Qin Empire, which has existed for about 700 years, and the Great Qin has occupied nearly 300 years of fighting against these infected monsters, according to our estimates, this feudal dynasty should also be under the oppression of this external force to exist for so many years."

"And at present, according to the information collected and corroborated in these books, Great Qin completely collapsed more than eighty years ago, because the number of this red mad wolf suddenly skyrocketed, broke through Great Qin's defense line, and entered its hinterland, and the entire Great Qin fought separately, and soon, it existed in name only."

"And before the collapse of Great Qin, they had already developed a powder gun, according to the final technology, it was about equivalent to the level of the Mauser 1888 rifle, and then because of the collapse of the entire dynasty, the basic rifle technology was maintained at this level."

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

This answer is also conducive to Jiang Yanhai's understanding of the scientific and technological level and part of the history of this world, but in fact, it does not have much effect.

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

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

"Understood."

In the next few days, Jiang Yanhai sent several different combat teams to start frantically capturing these red mad wolves, and the captured red crazy wolves were used as portals to expand behind them.

The larger diameter of the portal means that they can transmit more materials, but unfortunately it is located inside the secret base, in the belly of the mountain, which is estimated to transmit more things if it is in the plain.

A week after entering the portal, Jiang Yanhai's base began to take shape, and they were ready to take down the next town first, and that town would be used to communicate with these local residents in the future.

This portal will not be seen by anyone except Dai Yuan and the man Jiang Yanhai let go before.

It's just that Jiang Yanhai didn't wait for the next step of the plan, and he received an urgent message from the temporary headquarters.

"Report! Commander, we've spotted a large number of Red Mad Wolves coming in farther south, numbering at least a thousand, targeting Town 2 to the east. ”

"Prepare for the rescue!" Jiang Yanhai did not hesitate and made a decision directly!

PS: 7 more complete! I had a cold, and I was very uncomfortable. For the time being, we will not build a new group, and we will build it in two days. Thanks to the second leader of the Alliance Leader Bridge for the reward. Thank you brothers for your support! Asking for a commuter pass!!
