After this period of command, Brent had become very prestigious among the soldiers and policemen, and after his order was given, the remaining soldiers and policemen who remained in Raccoon City immediately took their families and rushed to the direction of the umbrella factory in the suburbs.

Li Yu also sent Xiao Yao with a thousand mercenaries on tanks and armored vehicles to meet him.

Since they are all his own people, Li Yu naturally wants to minimize their damage along the way, and he will no longer care about their lives and deaths as before.

By the time Xiao Yao led Brent's men to the umbrella factory, it was already dark.

Li Yu held a grand bonfire in the factory to welcome Brent and his men.

Tomorrow will be the day of the nuclear bomb attack, and there will definitely be nuclear radiation everywhere near Raccoon City in the future, and even if they want to go back to the surface, it will not be so easy.

Everyone was well aware of the situation, so the night was a great one.

To say that it was to welcome Brent was actually just an opportunity to vent their own fears and depression about the coming of the end times.

Li Yu did not stop this, and let everyone carnival all night until late at night.

"Order everyone to withdraw to the underground base and activate the maximum defense state of the base!"

After everyone dispersed, Li Yu immediately said to the red queen with a serious expression.

The Dragon's Lair Underground Base usually has three states: Primary Defense, Intermediate Defense, and Highest Defense.

In normal times, the base is only in a state of primary defense, as long as there is an access card that can be recognized by the red queen, you can enter and exit the base at will.

The intermediate state of defense is a situation where no entry is allowed, which is mainly to prevent the invasion of foreign enemies.

And the highest state of defense, and completely lock all the entrances to the passage in the base, neither enter nor exit.

Although the main target of the nuclear strike is the city center of the raccoon, no one can say whether they will drop a nuclear bomb on the suburban factory.

Li Yu naturally had to prepare for the worst.

"Yes, Boss!"

As the intelligent control center of the Dragon's Lair Underground Base Base, the Red Queen only needs a few seconds to complete the orders given by Li Yu.

"Click, click, click......"

With a soft sound, all the passages in the underground base of the Dragon's Lair have been completely sealed, completely isolated from the outside world.

And the oxygen production system in the base has also begun to work, and a steady stream of oxygen is diffused throughout the base, so that the people inside will not feel suffocated.

"Boom!"

The next day, most of the people in the base who had slept all night because they had been drunk last night were awakened by a loud noise of the earth shaking.

"What's wrong? What's going on!"

Everyone felt a violent shaking under them, and some did not understand what was happening, and there was a sudden panic and commotion in the entire base.

"There's a nuclear bomb attack going on outside, don't panic, as long as you stay inside the base, you'll be fine. ”

Li Yu's voice was transmitted to everyone's ears through the loudspeakers in the base.

Hearing Li Yu's words, everyone reacted, thinking that today was the day when the Mi Guo Zhengfu launched a nuclear bomb attack on Raccoon City.

"BOSS, according to the vibration frequency and the distance from the epicenter just now, what Mi Guozhengfu released just now should be a nuclear bomb with a yield of 10,000 tons......"

The red queen reported to Li Yu.

"Just a 10,000-ton nuclear bomb has such a great power, it seems that human thermal weapons still have a certain merit......"

Li Yu said solemnly.

The power of a nuclear bomb is directly proportional to its own yield, and today's nuclear bombs range from 1,000 tons to 10 million tons of yield, and a 10,000-ton yield nuclear bomb can only be regarded as a small nuclear bomb.

Li Yu knew that in the future, only those with extraordinary abilities would be able to deal with those extremely powerful zombies, and thermal weapons would gradually lose their effectiveness.

However, even those powerful abilities who can burn mountains and boil seas with a wave of their hands do not dare to stand directly in the center of the nuclear explosion to withstand the nuclear bomb attack.

It can be seen that the nuclear bomb, the most powerful thermal weapon of mankind, still has its advantages.

However, it is a pity that the central range of a nuclear explosion is not large, even if it is a nuclear bomb with a yield of one million tons, its maximum killing radius is only about six kilometers, and the central area of the nuclear explosion is only a few hundred meters in radius.

With the speed of powerful abilities and zombies, it's easy to escape the center of the nuclear bomb before it explodes.

As for the shock wave and radiation generated by the nuclear explosion, there is no longer much threat to Li Yu now, let alone those powerful abilities and zombies in the future.

Therefore, Li Yu's development goal has always been based on the evolution of abnormal abilities, such as tanks, armored vehicles and other thermal weapons, which can only play a certain role in the early stage of the outbreak of biochemical viruses, and when the zombies evolve again, it will be difficult to pose a threat to them.

"Boom!"

After about half an hour, everyone in the base heard a loud bang again, and a violent tremor was heard from under them at the same time.

If the previous tremor was only equivalent to a magnitude 4 earthquake, this time it was a magnitude 6.

Fortunately, the Dragon's Lair underground base is built very strongly, and even a magnitude 10 earthquake cannot destroy it.

However, this kind of shaking as if the sky was falling, but everyone in the base panicked, and from time to time a woman let out a scream.

"According to estimates, this time it was a nuclear bomb with a yield of 100,000 tons, located in the downtown area of Raccoon. ”

The red queen reported to Li Yu.

"Jims is a good mayor, it's a pity ......"

Thinking of Jims, who chose to stay in Raccoon City, Li Yu couldn't help but sigh.

He didn't pretend to be a gesture, but he really felt like this.

While it is better for Jims to die than to live, there is no denying that Jims is a good mayor.

The Red Queen couldn't understand the complex feelings of human beings, and was just silent after hearing Li Yu's words.

City Hall was located in the heart of the city, and if a 100,000-ton nuclear bomb had been dropped there, Jims would never have survived.

Nuclear bombs are a greater threat to cities than they are in the field.

In addition to shock waves and nuclear radiation, the resulting building collapses and fires are equally deadly.

The Red Queen calculated that if she wanted to completely destroy Raccoon City, only three nuclear bombs with a yield of one million tons would be enough.

However, if you want to kill all the zombies in Raccoon City, just three megaton nuclear bombs are not enough.

The ability of zombies to resist nuclear radiation and shock waves is far from being comparable to ordinary people.

Zombies that have been exposed to nuclear radiation for a long time can even undergo certain mutations.
