After Sun Dewang broke through the 4th level, the movement speed and duration of the heavy truck have also increased a lot, but he still needs to rest after driving for about six hours.

After a break in between, early the next morning, Zhang Dong and the others came to the range of Base 105.

I saw that the fourth line of defense of Base 105 was still in full swing, and the soldiers of the brigade were patrolling outside the defense line, clearing the strange beasts in the wilderness to prevent them from suddenly attacking the defense line and injuring the workers inside.

It is said to be the fourth line of defense, and after the first expansion of the base, this may be the third line of defense.

Now the total population of Base 105 is close to 900,000, and it must start to expand, otherwise, the entire base will be a little crowded if the population is increased.

The convoy quickly crossed the fourth line of defense, and the huge heavy trucks brought up puffs of smoke and dust in the wilderness.

The workers put down their work and looked at the convoy with curiosity.

More than 30 meters long, 10 meters wide and 10 meters high heavy trucks, in their eyes, are as powerful as steel giants.

"It's so tall and big!" the workers couldn't help but sigh.

In their opinion, the bigger it is, the stronger it is, and the height of this heavy truck is almost the same as the high wall of the 105 base, oh no, it should be a little higher than the high wall.

Such a behemoth, even if it hits the body of a giant beast, it is afraid that it will not be comfortable, right?

Thinking of this, the sense of security of these workers instantly improved a lot!

After passing through the fourth line of defense, which is being built, only thirteen of the fifteen heavy trucks remain.

Most of the materials pulled back from Base 91 were building materials, which happened to be unloaded here, and it was saved from running back and forth......

As for what you said about the first storage and then transfer?

What's the matter, Zhang Dong is also a general of the Special Operations Corps, although he has never been in charge of things, but he is also the existence of more than 10,000 people under one person in the 105 base, can't this matter be arranged?

When the convoy reached the high wall of the base, there was already a large group of men and horses waiting at the high wall.

This time he went out, and not only brought back a whole giant beast, but also brought back four half-step 5th-order corpses...... As for the other materials, it is a trivial matter, after all, the fourteen carts of materials are combined, and the corpse of a giant beast is worth a lot!

The expansion of the base is also underway, and the first line of defense has begun to be transformed, strengthened and connected, because there is a foundation of the defense line, so the progress of the expansion work is much faster than the progress of the construction of the fourth line of defense.

A simple outline can now be roughly seen, and in the middle of the original and new walls, various construction vehicles are constantly running back and forth.

"Haha, I knew that every time I sent Brother Zhang Dong out, I would definitely be able to get unexpected gains!" strode over, Zheng Yun laughed and patted Zhang Dong's shoulder.

The reconstruction of the base was jointly undertaken by Zheng Yun's garrison and the administration department.

The administrative department is a newly established department in the 105 base military and political separation plan, which is said to be a department, but in fact, the power of the head of this department is much higher than that of most ministers, and it is almost equivalent to the deputy commander of the base.

Not surprisingly, the head of the administration department is Zhuang Hongfei......

The departments of the garrison design and administration are now all divided, and the current task of the garrison is only to defend the various defense lines of the 105 base and clean up the alien beasts in the wilderness.

In the case of the special operations corps, it is only a little more than the garrison.

That is to carry out long-range special missions, such as supporting Base 91...... Explore nearby gathering places, persuade the other party to join the 105 base, and other tasks that require slightly stronger individual strength.

After a brief greeting with Zhang Dong, Zheng Yun commanded his subordinates to start moving the materials on the heavy truck.

Except for the heavy truck loaded with the corpse of the giant beast, the rest of the heavy trucks were temporarily left in place, and Zhang Dong, Sun Dewang and others drove directly into the base and drove in the direction of the research institute.

Fortunately, I have said hello in advance, and the slum area of the 105 base has now been renovated, and the road has been widened a lot, otherwise, it is really troublesome for heavy trucks to drive in the base.

Amid the cheers of the roadside residents, the heavy truck stopped smoothly in front of the gate of the institute, and the old man Gong and Li Mengli were waiting there early with a few researchers.

Among the several researchers in white coats, Lu Na, who was short in stature and immature-looking, looked particularly conspicuous.

As Sun Dewang put away the heavy truck, the corpse of the giant beast fell heavily to the ground.

A strong smell of blood and strong coercion instantly made the faces of several research institutes present pale for a while.

They are just high-level enhancement people's physical fitness, even if the giant beast has been dead for a long time, the power on their bodies that has not been exhausted still makes them feel uncomfortable for a while.

"This ...... Is it a complete giant beast?" Li Mengli couldn't help but gasp as she looked at the huge corpse in front of her.

A small part of the body parts of the giant beast obtained last time have already made a breakthrough in some research in Base 105, and this time a complete body of the giant beast has been obtained, which is undoubtedly a huge help for the current research of Base 105!

If you use it well, maybe the high-level enhancer potion will be able to go one step further!

"There are some other things. Zhang Dong smiled and glanced at Shang Rui behind him.

Shang Rui nodded, walked behind the giant beast, dragged out the corpses of four humans and laid them out on the ground of the research institute.

"There are still four half-step 5th-order corpses here, which should also be useful for some research, right?" Pointing to the four corpses on the ground, Zhang Dong spoke.

As for what is inhumane to do research on humans......

Zhang Dong is not a, human survival is the first, what is inhumane or not, wait for peace and contentment, and then think about it!

"General Zhang's harvest this time is very great!" Li Mengli's mouth was a little closed with a smile.

With so many top-level research materials obtained at once, I am afraid that breakthroughs can be made in many aspects of genetic research! The half-step fifth-order corpse is very helpful for the research of genetic warriors.

Four half-step 5-level corpses, if you're lucky, I'm afraid you can make a breakthrough!

Base 105 does not use Gene Warriors, that's because the Gene Warriors that can be bought on the market now are all stored in the back door of Base 1, not because Gene Warriors are not easy to use!

If Base 105 can independently produce genetic warriors, it will undoubtedly be huge for the overall improvement of Base 105!

After all, the population is now somewhat insufficient, but in order to defend the base, it has to ensure a large number of troops. As long as the genetic warrior research is successful, at least it can replace most of the soldiers who strengthen people!

Those soldiers who have retired from the army can join the engineering or other work, and a large number of jobs have a large number of high-level enhancers to join, and the increase in speed is not half a star!

"And the genetic armor, let's take it out together. Gong Yin said with a smile.

This little guy, do you have to dig out little by little, is it cool to pretend to be 13?

Touching his head, Zhang Dong smiled and took out three balls of meat of different sizes from his arms~ group, "Two are slightly damaged, one is basically intact, and it is more advanced than the biological armor provided last time, and the actual combat is also higher." ”

Looking at the biological armor in Zhang Dong's hand, Gong Yin's brows furrowed slightly, "Give the biological armor to Director Li, just leave the handover work here to them for the time being, you come with me." ”

With that, Gong Yin turned his head and walked towards the office area of the research institute.

"Brother Dong......" said hello to Zhang Dong, and Lu Na stuck out her tongue and didn't dwell too much.

The old man's expression could obviously be seen that he was looking for Zhang Dong to have something right, and it was definitely inappropriate for her to pester Zhang Dong at this time.

Smiling at Lu Na, Zhang Dong got up and followed the old man of the palace.

He could probably guess what the other party was trying to say to him.

This time, he killed three half-step 5th order directors in the black market, that is, he killed three directors on the other side......

The directors are already real high-level executives in the black market, and it is impossible for the other party not to retaliate.

Of course, with Zhang Dong's current strength, he is really afraid of the other party's retaliation, but don't forget, there are still top bases behind the black market, what if the top bases want to retaliate?

The two came to Gong Yin's office, and it was not difficult to see from the thin layer of dust on the coffee table that the office had not been to the office for a long time.

"The black market's recent tactics have become more and more aggressive, and they are directly in the sphere of influence of Base 91, directly threatening the base commander without any disguise, and snatching the corpse of the giant beast......" frowned, and Gong Yin's tone was a little serious.

"The top base behind the black market, is there going to be any action?"

Glancing at Zhang Dong, who was shrinking his neck, Gong Yin rolled his eyes and said, "Boy, nervous yarn, I didn't reprimand you when I called you over." ”

"Forehead ......" was seen through by Gong Yin, and Zhang Dong touched his nose a little embarrassed.

"I killed three directors of the black market, is there anything wrong? Will the other party send someone to take revenge on Base 105?"

"If you kill them, you will kill them, if you don't kill them, won't you stand and be beaten?" Gong Yin shook his head, "The revenge of the black market is not terrible, what is terrible is the meaning behind these recent abnormal behaviors of the black market." ”

"It's been an unknown number of years since the establishment of the black market, and everyone knows that there is a top-level base standing behind it, and they usually act in a low-key manner, so they just turn a blind eye. ”

"Now that the black market is becoming more and more arrogant, aren't you afraid that the top base will first eliminate them in order to appease the anger of the bases below? Or ...... What news did the black market get, knowing that the top base didn't have the time to deal with them recently, so you want to come out and see if you can make some benefits?"
