Shen Bai didn't want to be in a real crisis in the base, while defending against external enemies, he was also distracted to guard against threats inside the base.

Originally, he chose to accept ordinary survivors, just to be able to mine and mine to obtain survival points, but the premise of establishing these was the stable operation of the base.

But these mining survivors are just icing on the cake for the mining farm, after all, there are still hundreds of cards of black watch soldiers and mercenaries of the umbrella company in Shen Bai's hands.

Counting down, there are more than a hundred mercenary cards, and although ordinary black watch soldiers cannot mine, they can be used as transporters.

Therefore, the survivor labor force of the base was lost by three-quarters in this rebellion, but the impact on the development of Shen Bai and the base was not great.

……

After returning to the base, Shen Bai immediately asked the soldiers to send the evolution core to the underground base.

"Ding—Detected that the Commander has gathered all three Evolution Cores needed to upgrade the base. The three conditions for the second upgrade base have been met, whether to upgrade immediately. ”

The voice of the system sounded in Shen Bai's mind.

"Upgrade your base now."

Shen Bai didn't hesitate and immediately said to the system.

The upgrade of the base is not something that can be completed in an instant, it will take a long time, and Shen Bai did not continue to wait, but chose to go back to the house to rest.

The four supply boxes recovered this time, although they were far less dangerous than the one in Wuyun City, were far away, and in order to pursue the fastest speed, there was hardly any time to rest all the way, whether it was Shen Bai or the soldiers, they were exhausted.

……

The next day, the sun rose as usual, and when the remaining survivors set off to prepare for work as usual, they were surprised to find that the number of soldiers in the base had suddenly increased.

Originally, the wind and rain in the base were turbulent and people were panicking, on the one hand, Chang Shu was constantly demagoguery, and on the other hand, the weakening of the garrison force in the base was obvious to everyone.

If the soldiers in the base thought so much about today a few days ago, Chang Shu and his group would not dare to be so arrogant when they were killed, and eventually lead to self-destruction.

Li Yan's eyes lit up when he saw these soldiers.

He knew that since the soldiers had returned, Shen Bai must have also returned.

At this moment, Shen Bai had already gotten up and came to the command room of the underground base.

After a night of upgrading, the base is almost complete.

Sitting in the commander's seat, Shen Bai couldn't help but feel a little excited and apprehensive in his heart.

After the second upgrade of the base, what rooms will be unlocked, he is very much looking forward to it.

Finally, in the midst of anxious waiting, the voice of the system suddenly sounded in Shen Bai's consciousness.

"The base has been upgraded, and new rooms and features have been unlocked, please check it out for the commander."

Along with the sound of the system, there was a roar of mechanical gears turning, and a slight vibration of the underground base.

Shen Bai and the soldiers are used to this kind of movement, but this movement has shocked many survivors, the male survivors who have entered the mining area to work are okay, they can't hear any movement, but the female survivors in charge of logistics in the base are all frightened.

In Zhao Nina's office, Zhang Li was like a frightened rabbit, and said in a panic: "Sister Nana, no, is there an earthquake?" Is the outer wall about to collapse? ”

Zhao Nina has also seen a lot of things, and when she saw Zhang Li's appearance, she only felt funny, shook her head and said, "It's nothing, don't worry, it's just the sound of work over there." ”

"The sound of factory work? It's okay, it's scared me to death. ”

Zhang Li was still young after all, and she didn't have much knowledge, so she was easily fooled by Zhao Nina's casual explanation.

Zhao Nina thought for a while and said to Zhang Li: "By the way, you go to the kitchen and say it later, and ask them to leave a stove for me alone, and I will cook it myself later." ”

"Sister Nana, do you want to cook it yourself?"

Zhao Nina's words made Zhang Li's eyes widen in astonishment.

"Sister Nana, how can you cook it yourself?"

Zhang Li came to join the base after hearing the broadcast later, and at that time Shen Bai had already set off for Wuyun City to recycle the supply box, so she hadn't even seen Shen Bai, but she knew that Zhao Nina was the wife of the leader of the base.

Zhao Nina is simply an object of worship in her eyes, she is beautiful, her personality is mature and stable, and she is the image of a standard strong woman.

She couldn't imagine that such an excellent woman would actually go to the kitchen.

Looking at Zhang Li's surprised expression, Zhao Nina smiled slightly, "You just have to go and command." ”

Usually when Zhao Nina is alone, of course she doesn't cook by herself, but today is different, Shen Bai is back.

In the past, when there were not many people in the base, Zhao Nina cooked for Shen Bai every day, her cooking skills were very good, and she also liked Shen Bai very much to enjoy the process of the food she made.

Even though she now has more than a hundred logistics staff under her hands, and there are more than a dozen aunts with good skills in the kitchen alone, she is not ready to hand over Shen Bai's food to others.

……

"Commander, the base has been upgraded, and the three rooms have been unlocked."

In the command room of the underground base, Empress Bai said to Shen Bai.

"yes, I know." Shen Bai nodded slightly, and he couldn't wait to check the changes in the underground base on the big screen in front of him.

At this glance, Shen Bai couldn't help but laugh.

The three rooms unlocked this time have a radar room, an armored car manufacturing room, and a weapon manufacturing room.

To put it simply, with the exception of the radar room, the other two combined together can be summed up in an arsenal entirely.

I also want the arsenal to work, in addition to the main control of the white queen, I also need some workers to assist.

As for the radar room, for the current Shen Bai, it is dispensable, after all, Bai Hou has now controlled some civilian satellites, which are enough for communication near the base.

Although radar also has this effect, the main effect of radar is to guide air troops and warn of air enemies, so it seems to be a bit chicken at present.

……

In order to suppress these survivors, Ada Wang directly used the sentry cannon and killed more than 300 survivors, so there are only more than 100 survivors left in the mine who are still working in the mine, and the mining efficiency has plummeted.

"In this case, if necessary, you may need to consider letting the mercenaries also go to the mining area to mine......"

Shen Bai sighed helplessly.

At present, the gold mine base, when running at full capacity, can obtain thousands of survival points every day.

Although more than 300 survivors died, if Shen Bai put the current more than 80 mercenaries into mining, with the strength of the mercenaries, the efficiency would definitely far exceed that of the three hundred ordinary survivors.

……

In the Zhangjia Gold Mine Mine, there were suddenly more than 300 people missing, and the cave was much more deserted all of a sudden.

This somewhat made the remaining more than 100 survivors feel very uncomfortable, no matter what, the people who were working together a few days ago disappeared in a blink of an eye, this feeling is not that the parties have no way to understand, and many survivors are a little absent-minded when they do their work.
