The last leader of the world starts with an elite infantry squad!

During the mutant zombies' repeated attacks on the 77th Legion in Beipei District, not only did their numbers increase, from a few thousand at the beginning to tens of thousands, and then to tens of thousands recently!

The types of them are also increasing at an extremely exaggerated rate, it’s like the other party is using the 77th Legion for product testing!

After every attack by mutant zombies, the 77th Legion would be able to find new mutant zombie corpses while cleaning the battlefield!

There is no end to the research! There is no end to the research!

We haven’t figured out the last batch of new zombies yet, and this new batch is coming. The large amount of zombie materials almost overwhelmed the doomsday research center established by the 77th Legion!

The research speed of the experts and professors at the research center cannot keep up with the speed of its research and development!

These mutated zombies are divided into categories based on their functions, including those with high speed, those with great strength, those with accumulated muscles, those that can spray acid, and even those that can glide for a short period of time!

If we divide it by shape, there will be even more!

Some look like humans, some look like mice, some look like cats, some look like dogs, some look like geckos, some look like a combination of two lizards and dogs, and some have strange shapes and are nothing like them!

The speed of iteration is so fast that some of the big technology companies before the end of the world can’t even see their taillights!

However, although there are many tricks, none of them will force the troops to use the ultimate bomb - the tactical nuclear bomb!

The real reason that made Yu Zhengguo determined to use tactical nuclear bombs at all costs was:

During today's routine attack by mutant zombies, the troops recovered a special mutant zombie!

How special is it?

The troops discovered that the zombie's flesh and blood was actually wrapped in a palm-sized steel plate...

At first I thought it was shrapnel or something and didn't take it seriously. After all, the situation on the battlefield was complicated and anything could happen.

But soon researchers discovered something was wrong!

A young researcher at the research center dissected several zombies of the same appearance based on his intuition!

It was discovered that the bodies of these zombies were actually wrapped with metal objects of different sizes...

Then he quickly came to a horrifying, but very reasonable conclusion:

The zombie hive seemed to realize that it could not fight against the army just by relying on the changes of its flesh and blood, so it began to seek materials outside of itself!

Using “tools” ignorantly?

When this discovery was first reported to Yu Zhengguo, his first reaction was disbelief, and then a chill ran down his spine...

Through fighting against zombies, these soldiers are actually not that worried about zombies and generally believe that they do not pose any threat.

Anyway, people will die if they are shot. The only difficulty is to increase the output of weapons and ammunition. And the increase in the output of weapons and ammunition can definitely be achieved as the industry recovers!

So in their opinion, no matter how many zombies there are, it is only a matter of time before they are eliminated!

But now suddenly someone told him that this was not the case!

The outbreak of the apocalypse and the destruction of the technological industry chain have pushed human military power to its limits!

However, the zombies are far from reaching their limit and are rapidly climbing up in a way that they cannot understand!

Who can bear this result?

It’s not out of fear of the zombie hive using “tools”, but out of fear of their learning speed!

No one knows what the original zombie hive looks like better than Yu Zhengguo!

His evaluation of it is:

Not dead but toys!

But now, in just less than two months, the 77th Legion is like the master of this zombie hive. In the non-stop attacks, it has trained it into its current state!

It's so smart!

Just like it took only two months to evolve from a single-celled organism to the point where they can use tools...

What's next? ?

How far will it evolve?

This made many experts who wanted to use it for observation experiments dare not gamble...

No one can guarantee what kind of monster will appear if we continue!

Human civilization is already in turmoil and can no longer withstand the turmoil!

So even though they were extremely reluctant, the many experts and professors housed by the 77th Army Corps still petitioned collectively, hoping that Yu Zhengguo would destroy it at all costs!

.....

Although he wanted to go out to see the scene of the destruction of the zombie nest, Yu Zhengguo did not get carried away. He waited until the experts had tested the surface radiation indicators and confirmed safety before going to the surface under the protection of the guard squad!

Not to mention that the entire human race is in turmoil, his 77th Legion has also been in turmoil for a long time!

Now, as long as he is alive, he will contribute to the entire Yucheng!

...

Huhuhu~

The sound of violent wind rang in his ears. He didn't know if it was an illusion, but Yu Zhengguo always felt that there was a rusty smell in the air that made his nose itchy.

The gray-haired man stood on a high observation tower in the gathering place, holding a high-powered telescope and gazing far into the distance in the direction of the urban area of ​​Yucheng!

But no matter how he adjusted the magnification and focal length, he could only see a mushroom cloud several kilometers high composed of fireballs, dust and ash debris over the city of Yu!

Looking at this hellish scene, Yu Zhengguo was not afraid at all. Instead, he seemed very excited!

This was also the first time he witnessed a nuclear bomb exploding in a human city. Before coming up from the underground command post, he was a little worried that the destructive power of this nuclear bomb was not enough!

After all, it is just a small tactical nuclear bomb with an equivalent of 1 tons. Compared with those strategic nuclear bombs with an equivalent of millions or tens of millions of tons, it can only be regarded as a small Karami!

If the power is not enough, then we will be completely helpless against the opponent!

After all, nuclear bombs are not something that the army can control, and this tactical nuclear bomb was obtained by luck.

It was obtained from a secret third-line nuclear military factory in Yucheng. I don't know whether it is used as a product or a research sample.

At that time, several nuclear industry experts were rescued. Unfortunately, this factory did not have the ability to independently manufacture nuclear bombs. It was just a link in the nuclear bomb production chain.

"Dr. Zhao, this power should be enough, right?"

Yu Zhengguo still felt uneasy. After putting down the telescope, he asked a bald middle-aged man standing next to him.

It’s not his fault for being too cautious, it’s because he has too few nuclear bombs!

The old problem of fear of insufficient firepower has come back again!

When Yu Zhengguo thought of the abnormal abilities of the zombie hive, he wished he could drop dozens of nuclear bombs!

As if he had noticed Yu Zhengguo's worry, Dr. Zhao reflexively adjusted the lenses on his nose, allowing the aura of his knowledge to radiate from within.

Does Dr. Zhao understand what Yu Zhengguo wants, his professional knowledge?

of course not!

What leaders want is emotional value!

Since we want to give emotional value to the leader, we should first force ourselves to pretend to be so. The more professional you are, the more at ease the leader will be!

"Don't worry, Commander. The zombie hive is definitely dead. To use the words of the liberal arts department, it has been reduced to ashes!"

"This nuclear bomb can cause three fatal injuries to the zombie hive!"

"Oh?"

Looking at Dr. Zhao, who exudes an intellectual aura, especially his bald head who shows strong professional ability, Yu Zhengguo can't help but feel relieved.

He is so bald, he must be very strong, right?

As the commander of the legion, how could he not know the principles of nuclear bomb explosion?

But knowing is one thing, and hearing it spoken by a professional is another!

Just like when you are sick, some people know that they are most likely to have a cold, and can even differentiate between a common cold and a viral cold, but they still have to go to the hospital to hear what the doctor says in person before they can feel at ease.

This is called professionalism!

Similarly, Yu Zhengguo was also willing to listen to Dr. Zhao say it again.

Dr. Zhao naturally understood the meaning of the song and immediately introduced it.

"This first level of lethal damage is that within less than a second of the nuclear bomb exploding, a plasma ball hotter than the sun will appear!"

"Commander, think about it, is there anything on Earth that can face the sun directly?"

"The second level of damage is the extremely high temperature heat pulse. This heat pulse..."
