After returning from the Hungry Wolf Gang's stronghold, the first thing Ye Bing did was to go straight to the base!

Does the reason need to be explained?

Of course, hurry back and upgrade the base!

Along the way, Ye Bing turned on the maglev firepower, almost flew through the sky, and returned to the base.

As for whether he will be discovered along the way, it is no longer a place he can take care of.

Because if you drive slowly, you will be detected, and if you drive fast, you will also be discovered, and it is better to be faster, which can also reduce the risk of being detected in time.

As soon as he entered the gate of the base, Ye Bing threw the big bag full of magic crystals on the ground like an upstart.

"Fill me!"

He gave a heroic order, and immediately the sappers stepped forward to complete the task for him.

And he himself stared straight at the big screen, watching the attributes of the energy reserve column constantly change-

350…… 400…… 450…… 500！

At the moment when the number of inferior magic crystals was filled to 500 and the number of ordinary magic crystals reached 5, the originally red button under the main base suddenly turned green!

"It's time to upgrade!"

Ye Bing took a deep breath.

At this moment, he felt as if the whole world was his!

In the next second, he didn't hesitate to click the "upgrade" button!

In an instant, Natasha's voice floated over the base:

"The upgrade of the main base will consume five hundred low-quality magic crystals and five ordinary quality magic crystals, and the upgrade lasts for nine hours, during which the main base will not be able to complete the manufacturing and production tasks, and all non-digital lifeforms must not stay in the main base. Do you confirm the upgrade? ”

Ye Bing pondered for a moment and asked:

"So, as soon as the escalation is confirmed, I have to leave right away?"

"You have a safe stop period of up to thirty minutes. After the end of the safe stop period. If you remain in the main base, you will be randomly teleported to any location in the base area by the Doom base. ”

Ye Bing nodded.

He thought about it, and basically did everything that should be done.

The remaining little tail can be done in thirty minutes, and there is no need to drag it out.

Thinking like this, Ye Bing said decisively:

"I confirm the upgrade!"

The moment his words fell, the ground under his feet suddenly shook, and all directions in the base lit up with faint blue lights.

"The upgrade begins...... ...... countdown to the safe stop period"

The picture in front of me began to become hazy, as if it were real and illusory. Everything seemed so unreal.

Ye Bing looked down in surprise. I found that my body, like everything around me, had become extremely ethereal and unreal.

In an instant, the main base seemed to fall into the blue ocean, and the air was rippling with sparkling waves, like waves in the sea.

Looking at this scene, a word suddenly popped into Ye Bing's mind.

Digitization.

Perhaps, this is what the main base will look like after the initial data.

And as a non-digital self, if you continue to stay. It is likely that it will not be able to withstand the data flow and will be compressed into meaningless garbled characters......

It feels ...... It's amazing!

Ye Bing was attracted by this scene for a while, and then set out to get down to business.

He got three hundred and twenty magic crystals from the Hungry Wolf Gang, counting the previous three hundred and fifty. There are 670 in total, and 170 remain unused, excluding 500 for upgrades.

But this part of the magic crystal, Ye Bing did not plan to use it immediately.

He guessed. After the main base is upgraded, these magic crystals are likely to come in handy.

However, except for this batch of magic crystals. There is still a significant amount of energy stored in the base.

These energy reserves all came from the recovery of zombie corpses, and after a few days of collection, they also reached two hundred and seventy points, which is not a small amount.

Ye Bing decided to use all this energy on the blade.

Previously, by killing a team of soldiers from the Deep Water Military Region, Ye Bing intercepted a lot of new gadgets, including military-standard submachine guns and grenades.

When used in larger military battles, these two weapons are obviously much more useful than assault rifles.

Therefore, after bringing the things back, Ye Bing tried to replicate the two weapons.

Again, it's not expensive.

Each submachine gun costs two charges, and the clips are cheaper, producing nine for each charge.

As for the grenade, perhaps because of the lower technology content it contains, the price is as cheap as three rounds per point of energy, which is super cost-effective.

So, Ye Bing simply exchanged fifty submachine guns, more than 100 submachine gun magazines and nearly 100 grenades in one go, spending a total of 200 points of energy!

In addition, Ye Bing spent all the remaining seventy points of energy, and produced seventy sets of tights in a row.

As one of the most cost-effective items in the entire base, the production of tights at this time can undoubtedly greatly increase the probability of survival for the team members.

At least in the face of submachine gun bullets, the tights can still stall so many rounds, and its defensive effect is definitely not worse than that of body armor.

After doing all this, Ye Bing's heart finally had some more confidence.

Although in terms of numbers, the other party far surpassed his own side, but fortunately, the venue was advantageous to Ye Bing's side.

Because they were in an environment full of zombies, a large tank force could not drive in at all, so the thousands of soldiers of the Shenshui Military Region could only disperse and invade on foot.

This also means that, in terms of weapons, the two sides will not be too far behind, at most dozens of anti-aircraft guns.

But Ye Bing, who has reconnaissance methods that surpass the other party by several levels, how could he stand in the same place and wait for the bombardment of the opponent's shells?

Of course not.

Ye Bing will take advantage of the priority of reconnaissance information to organize a counterattack first, and tear a hole in the opponent's formation before the opponent's formation is formed!

As for the follow-up work, I'll leave it to the Doomsday Base and the Mech Corps!

When everything Ye Bing was ready to do was done, there were still more than five minutes left in the countdown to the safety stop.

Ye Bing packed his things, and then left the Doomsday Base with the Mechanized Corps and headed for the new safe zone.

Near the New Territories troops, Ye Bing settled the mechanized corps and drove all the weapons and equipment to the New Territories troops' base area.

There, Su Chengtian and the others, who had received the information early in the morning, had sounded the highest alarm, and all members of the New Territories were on standby, ready to start fighting at any time.

No one knows who the enemy they are about to usher in.

But they knew that the other side was the one who was going to take their land, take their relatives, and take their lives.

Therefore, no matter who it is, they have raised their vigilance at this moment and waited for the day to resist the incoming army!

As for Ye Bing, after arranging the affairs of the New Territories troops, he returned to the old security zone! (To be continued.) )
