The 　　　　 convoy quickly returned to the vicinity of the camp. The forklifts in the camp were already ready. Professor Xu in the base had arranged seven or eight energy-detecting machines on both sides of the entire portal.

After all these instruments started to operate, a forklift immediately forkped an iron cage and walked directly into the portal. When the iron cage forklifted by the forklift, that is, the red mad wolf, passed the portal, the entire portal used naked eyes. The visible range has expanded a bit.

Not only Professor Xu, but Jiang Yanhai drove the advanced scanning program nearby. Even the advanced scanning program did not find any abnormalities. Anyway, when the Red Crazy Wolf was sent to the other side, the entire portal was directly without warning. Expanded a little bit.

　　 There seems to be no connection between the two.

　　 The research still needs to be researched. After 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 crossed to the base, the portal expanded a circle, and there was the last one left. Professor Xu and the others did not let them do it, instead they prepared to dissect and test it directly here. .

　　 These tasks are not what Jiang Yanhai and the others need to worry about. In fact, if even advanced scanning programs cannot find anomalies, there is a high probability that these modern instruments will have no way to detect anomalies.

Instead, drones in the air are constantly taking pictures of the terrain, and then continuously expanding the shooting range. This pterosaur has a limited ceiling, and the maximum ceiling is about 8000 meters high in the sky, with a resolution of 6 meters. The photos can be taken with a radius of about 15 kilometers.

　　 Calculated according to the maximum operating distance of 20 kilometers, it can capture all terrain within a radius of 35 kilometers. The land area is close to 3900 square kilometers.

　　 "The report is about 28 kilometers to the east of us. There is also a small town whose area seems to be larger than what we have found so far." The drone operator here finally made a new discovery.

　　 "Is there no other discovery other than that?" Jiang Yanhai looked at him and asked.

　　 "Report, no."

　　 "Send a team to set up a temporary relay signal tower to increase reconnaissance in the area." Jiang Yanhai pondered for a while, and then issued the latest instructions.

"Yes!"

　　 Following Jiang Yanhai’s order, a special forces team, together with two Bobcat assault vehicles and two trucks loaded with simple signal towers, quickly moved forward to the area.

　　Between the base and this small town, there is a not-so-high mountain that just happens to be able to build a simple signal relay tower.

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

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

　　 The speed of the signal tower team was very fast. The construction task was completed in less than 3 hours. When the construction task was completed, the pterosaurs began to hover over the small town for reconnaissance.

　　 It does not need to descend, even if it is daytime, people on the ground can't find the existence of drones at all. When sending this team out, Jiang Yanhai sent three more teams to **** Professor Xu and his 6 scientists to the slaughtered town.

The purpose of escorting these scientists in the past is to check and search the entire town to see if they can get some useful information, such as books. You can understand the situation here through these aspects. At present, Jiang Yanhai's eyes are black, most of them All guesses came from Dai Yao and the man he had caught before.

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

　　Professor Xu sent out and they returned after 5 hours. They really found a lot of books in this town.

　　 But 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, Xia Yan country, because in ancient times they believed that they originated from two primitive tribes called Xia Heyan."

"And their last feudal dynasty is called the Great Qin Empire. It has existed for about 700 years. Among them, Da Qin fought these infected monsters for nearly 300 years. According to our estimation, this feudal dynasty should also be here. Under the pressure of this kind of external force, it can exist for so many years."

"According to the information collected and corroborated in these books, Da Qin completely collapsed probably more than 80 years ago, because the number of red mad wolves suddenly increased, breaking through Da Qin’s defenses and entering its hinterland, all over Da Qin. Fight separately, and soon, it will exist in name only."

　　 "Before Daqin collapsed, they had already developed a gunpowder gun. According to the final technology, it was roughly equivalent to the Mauser 1888 rifle. Later, due to the collapse of the entire dynasty, the basic rifle technology was maintained at this level."

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

　　 This answer is also helpful for Jiang Yanhai and the others to understand the technological level and part of the history of the world. In fact, it does not have much effect.

　　 "Professor Xu, please report this news. We may still have to establish a safe line of defense before you can conduct a complete research." Jiang Yanhai thought for a while and said seriously.

　　He is the highest commander here, so Professor Xu and the others will also have to communicate with Jiang Yanhai how to study.

　　"Understood~lightnovelpub.net~ In the next few days, Jiang Yanhai sent several different combat teams and began to frantically capture these red mad wolves, and the red mad wolves caught were used as and expanded the portal behind him.

　　 The larger diameter of the portal means that they will transmit more materials. It is a pity that it is located inside the secret base, in the mountainside. If it is in the plain, it is estimated that it can transmit more things.

　　 After entering the portal for a week, Jiang Yanhai and his base have begun to take shape. They plan to take down the nearby town in the next step, which will 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 received an emergency from the temporary headquarters before he could make the next plan.

　　 "Report! Commander, we have discovered that a large number of red crazy wolves have gathered. They have rushed from further south. There are currently at least thousands of them. Their target is our No. 2 town found in the east."

　　 "Ready to rescue!" Jiang Yanhai made the decision without hesitation!
