However, this time, after pressing the button, the underground passage was not immediately cleared, but was always wrapped in a ball of light, and a line of small text appeared on the screen:

Time remaining for clearance: 2 hours 31 minutes

It seems that it takes time to carry out such a large project at once. Ye Bing said secretly in his heart.

But it doesn't matter, there are other things that need to be done anyway, so let it clear slowly first.

He looked up and could see through the transparent protective layer that the sky outside had faintly turned gray, and night was soon approaching.

"It looks like we're going to have to wait until tomorrow if we want to leave the base. Later, even if the passage is dug, it will be dangerous to run out. ”

He looked down and thought about it, and decided:

"In that case, let's first produce all the troops that should be produced, and prepare for tomorrow's action."

Just as he was about to turn the screen to the mechanical barracks, something suddenly came to his mind!

"Oops! How did I forget that! ”

Ye Bing patted his head, and instantly remembered the promise he made with Su Chengtian and the others!

If memory serves, he said that they would come and get the guns in five days, and now it should be exactly the fifth day, right?

If they had been punctual, they might have arrived by now!

"Alas, forget it, there's no way, even if you're in a hurry, you can't get out now. I can only hope that they will come back tomorrow. ”

Ye Bing shook his head. In fact, in his heart, he was very willing to help Sioux City dump them. In these last days, it is the luck of the whole world to have such an organization as a black crescent.

As for how to conjure up gunfire with his bare hands, he already knew this.

He took out his assault rifle and magazine from the military hiking bag he was carrying, and then walked out of the base gate and headed towards the tech tree!

Every time he faced this extremely magical tree-like building, Ye Bing always had a feeling that he had gone to the wrong world.

He looked at the technology tree fixedly, his mind moved, and he muttered:

"Turn on replication."

As soon as the words fell, the technology tree seemed to understand his words, and a container with a volume of dozens of liters popped out of the "tree hole" in its body, and some kind of boiling liquid was beating inside!

Ye Bing licked his dry lips, and without much hesitation, he resolutely threw the assault rifle into the container along with the bullets!

Plop, plop.

Two water sounds sounded, splashing in patches.

Ye Bing took a step back and ordered again:

"Make a copy!"

After receiving the order, the container filled with the unknown liquid was slowly retracted. In the next moment, the rows of small lights hiding in the canopy of the tech tree all lit up, instantly illuminating the originally dim tech tree!

Less than a minute later, the rows of lights in the canopy went out, signaling that the replication process had been completed.

The assault rifle and magazine were bounced out of the tree hole and landed at Ye Bing's feet.

Ye Bing squatted down and picked up the guns and ammunition that were still stained with viscous liquid, and he didn't show worry or disgust on his face, because he understood that the functional liquid in the technology tree had no corrosive effect at all, and would not damage either the human body or the guns and ammunition, as long as it was after a while, they would automatically evaporate, and there was no need to wipe them at all.

Ye Bing returned to the main base, opened the interface of the technology tree, found the "Replica" column from it, clicked in, and found that there was an extra option in the originally empty column:

QB-Z95 rifle.

Ye Bing clicked in and took a look, but was taken aback by the large list of options!

Good guy, you copied a gun yourself and made so many things?

He took a closer look and saw that the list contained really what was included in the firearm, but it was subdivided. It can range from circlips, gunpowder, and iron sheets to entire guns.

Ye Bing smiled, he didn't have the slightest interest in assembling it himself after exchanging it, so he directly clicked into the whole gun column.

Immediately popped up the copy price of the whole gun from the interface -

2 energy spend/put.

This price is still quite conscientious, and it seems that the technology tree should be the default reason for the low technology content of assault rifles and the ease of manufacturing.

He found the "magazine" column from the list, clicked on it, and found that the price was-

1 Energy Cost/5 sticks.

Seeing this, Ye Bing was finally moved!

He has been a base commander for so long, and it is the first time he has seen such a conscience in the base!

He had guessed that even if the magazine was cheaper, it would only cost 1 point of energy for one, but he didn't expect that the technology tree would give 1 point of energy for five!

In this case, there is basically no need to worry about running out of magazines in the future.

After thinking about it, Ye Bing finally exchanged for five assault rifles and twenty-five magazines, spending a total of 15 energy points.

Although these equipment can't arm the entire Black Crescent team, they can at least improve their combat ability by two grades!

When the time comes, when facing ordinary gangsters, there is no need to move at close range, and long-range fire strikes alone are enough to destroy a small gang.

In addition, he originally wanted to exchange a few tights for Su Chengtian and the others. Because the price of each tights is not expensive, just 1 point of energy, and their own physical fitness is very strong, they have a martial arts foundation, and the strength bonus of wearing tights will be higher, and they can also resist damage, avoid being bitten by zombies, and can highlight their proud figure to the extreme......

But despite this, he didn't choose to redeem it in the end.

If there is such a thing as guns and ammunition, and it can be explained as a military weapon, it is easy to make people suspicious of super technology such as tights.

Regardless of whether others will say that he is cautious, or that he is cowardly and afraid, in short, until he confirms that he has sufficient self-protection ability, he will try to avoid revealing the affairs of the base as much as possible.

In addition to this reason, it is also because of the lack of energy. If you have more energy to spare in the future, you may want to consider other ways to help them.

After taking care of the guns and ammunition, Ye Bing jumped back to the mechanical barracks.

The buildable classes are still the same, with only one more recovery vehicle.

Ye Bing thought for a while and asked Natasha:

"If you upgrade the mechanical barracks, what kind of new classes will appear?"

Natasha immediately replied, "You will unlock the manufacturing rights of air units and vehicles. ”

Air units and vehicles?

Ye Bing muttered again.

Sounds pretty good! At least at this stage, if you really get a few combat units flying in the air, you can almost do a one-sided slaughter against the primary zombies. The reason is also very simple, zombies have no ability to fight against the air!
