Ye Bing walked into the entrance of the offensive and defensive area, and walked towards a pile of corpses of first-order zombies alone.

He first walked over to the corpse of the red zombie.

took out the corpse sword at his waist, and slammed it into the heart of the red zombie!

However.

When the tip of the sword touched the heart of the red zombie, the corpse sword was forcibly stopped.

Ye Bing raised the corpse sword with a calm face, inserted it again, raised it, and inserted it again.

After repeating it five or six times, the tip of the sword finally broke through the skin of the red zombie and inserted it into the heart!

It took a lot of effort for him to pull out the corpse sword again.

He retracted the corpse sword, removed the assault rifle from his shoulder, pulled down the safe, and opened fire on another intact spot on the red zombie's body.

Bang, bang, bang.

Shot after shot, three shots in a row.

Although the red zombie's skin was torn apart by the first shot, it was not until the third shot that it was completely penetrated.

This means that in the case of primary zombies, the effect of one shot will be divided by three in the case of red zombies.

But fortunately, judging from this test, this level of firepower of the rifle can still pose a threat to the first-order zombies.

But it is estimated that it is limited to red zombies and sentinel zombies.

Facing the green zombies that couldn't even cut through the lightsaber, Ye Bing didn't even have the mood to try it at all.

With a gloomy mood, Ye Bing silently walked back to the main base alone.

The main base properties are displayed on the large screen.

Ye Bing raised his eyes and found that the energy column had changed from the previous "155" to "157+13"!

What does this mean?

This means that the thirteen zombies before not only brought thirteen inferior magic crystals to the base, but also contributed two points of energy with the corpses!

This value cannot be said to be less. Although it is only two points, the energy ratio is more than double that of before.

You know, in the past, it would take close to forty corpses of primary-grade zombies to convert two points of energy.

There is a way to have money in your pocket. Don't panic.

Risk and income go hand in hand. This phenomenon made Ye Bing see that as long as he continued to develop, the harvested energy would always continue to grow.

At this point, his dull mood was finally relieved a little.

However, looking at the attributes of the main base, there was a question on his mind.

How do you use such a large amount of energy?

He thought about it for a moment and finally set his sights on two places.

First, the mechanical barracks.

Second, the Zombie Research Institute.

The first one naturally doesn't need to be explained. The main thing is to talk about the second.

The Zombie Research Institute is one of the five buildings unique to the Legends of Mankind.

As for the function, the introduction says "zombie samples can be added to it, corresponding to the research and development product".

Judging from this introduction, it should be specifically for zombies, which is not too much of a problem.

And what Ye Bing needs most at the moment is a way to deal with zombies.

It is clear from several previous tests. With the current level of mechanical soldiers, it is no longer possible to deal with a large group of zombies.

Unless he can assemble a real mech, there are hundreds of mechs. But this is clearly not possible.

Not to mention how much energy is needed to produce so many mechs, just the energy and ammunition consumed for each expedition. It's not what Ye Bing can afford now.

Therefore, if you want to gain a foothold in today's last days, or even dominate, those things of the past alone will no longer work. He must find a new way to rise.

Of course, one thing won't change anyway.

That's-

Drugs.

Of course. It's just an entertaining statement, and the serious way to put it is that it is a continuous injection of genetic enhancers.

This stuff is undoubtedly very useful.

So far, Ye Bing has only injected two gene-enhancing elixirs, but the improvement of all attributes of the body is already obvious.

If there is a specific manifestation, it is that the strength has increased, the senses have become sharper, the agility and the speed of the mind have increased, and even the flesh and skin have become strong and resistant.

Of course, this level of resistance is still far from that of first-order zombies, and Ye Bing, as a human being, has never thought of surpassing them at this point, at least at this stage.

Therefore, from the above points, it seems that as long as the genetic enhancer continues to be injected, in the near future, he is very likely to become a similar "superhuman" existence in the human community.

At that time, he may also be able to face several first-order zombies without having to turn around and flee in embarrassment!

The topic returns to the Zombie Institute.

Although he didn't know what could be researched inside, Ye Bing still had a lot of interest.

Even if he couldn't research any powerful weapons, even if it was just to provide some weaknesses on the Hulk zombies, it would be worth Ye Bing to pay for the dozen inferior magic crystals.

Speaking of weapons, this has always been something that Ye Bing desires and has a headache for.

As a modern man, in his mind, naturally no weapon is as refreshing as a thermal weapon of mass destruction.

No matter how rough the Hulk zombie is, it is only a first-order zombie in the final analysis. If a rocket goes down, as long as it is within the bombardment range, no matter how many Hulk zombies will turn to ashes.

Even if you don't have a bazooka, just a heavy machine gun or a high-speed machine gun of Gatling's grade will do, with a rate of fire of 6,000 rounds per minute, as long as there is someone in front of you to protect you, it will only be a matter of minutes to destroy more than 100 zombies!

But it's a pity that none of the above heavy firepower is available in the base.

Ye Bing had also searched for heavy firepower in the free forging system of the forging factory, but there was no response.

Well, if you still want to produce heavy firepower, there are only two ways. Either get a physical gun and throw it into the tech tree to copy it, or simply get the detailed drawings of the gun and let the tech tree scan it, which can also achieve the effect of copying.

But if these two paths don't work, you can only put this matter aside for the time being, and wait for the opportunity to slowly try it out later.

In such an environment, it is very necessary to create a zombie research institute.

However, at present, the base only has thirteen inferior magic crystals stored, and a zombie research institute needs fifteen inferior magic crystals, and it will not be built until the recovery vehicle cleans up the zombies outside.

So, for now, he has to turn his attention back to the mechanical barracks.

screen jumps to the Robo Barracks screen.

When he saw the "twenty-five energy spending" required for upgrading, Ye Bing couldn't help but sigh in his heart.

For him ten days ago, this amount of cost was tantamount to a sky-high price, but for him now, this amount of energy is nothing.

Of course, he could have upgraded it to LV2 the day before the Second Cataclysm, but he didn't do so because there were other considerations.

I'll leave that later.

Ye Bing didn't hesitate, and directly chose the upgrade button.

Soon, a familiar white ball of light enveloped the mechanical barracks.

In an hour, the LV2 level mechanical barracks will be released! (To be continued.) )
