The first killing, four in a row.

Even if it was a sickened person with bad intentions, Zhou Yan still felt that his hands were trembling, and he was holding back a fire in his heart when he killed the sickened person. He comforted the other party with kindness, but the other party was planning to kill him, so he was swayed by anger at that time and killed four sick people without mercy.

Now when I walked out of the building and looked at the sun in the sky, I realized that I had killed a living human.

Not bugs, not zombies.

Fortunately, he is not a person who likes to drill the horns of the bull, and the first hand of the sick person is the first to move, even if it is placed before the end of the world, shooting them himself can barely be regarded as legitimate defense.

"If they don't die, they will take revenge on normal humans after all, and they carry the T virus all over their bodies, which is a source of infection that is even more terrible than zombies. Zombies are muddy, they can be killed easily, and the sick people have the wisdom to use the means......"

Shake your head.

Zhou Yan's trembling hands gradually calmed down, and he soon left the fear of killing behind. In the end times, people have to learn to face all kinds of distorted scenarios.

He continued to drive the BAIC Warrior, hunting insects from west to east along the North Second Ring Road. He would need to hunt at least two hundred bugs to gather an estimated 1 kilogram of energy crystals. Now that the Evolution Liquid and Radiant Gas are in surplus, only the Energy Crystallization and the Variety Ore are far from enough.

"Bugs, the more bugs, the better."

Zhou Yan held a high-energy pistol, found the insect and immediately shot it to take blood, a thousand calories of a hot bullet, the power is much greater than imagined, within the effective range of fifty meters, any bug, zombie is a shot fatal. Even a brick wall more than 20 centimeters thick can be fused through.

He also experimented with steel plates, the kind of car steel sheets half a finger thick, which were also melted through by hot elastics.

This power is already a sniper rifle.

However, after exceeding the effective range of 50 meters, the energy of a 1,000-calorie hot bomb will quickly decay, and even a few centimeters thick wooden planks cannot be melted. The attenuation coefficient of this distance and power is quite special, and it is very different from ordinary mechanical kinetic firearms.

Generally, the closer the pistol, the more powerful, and the farther the distance, the less powerful.

High-energy pistols, however, are almost as powerful as hot bullets within the effective range, and when they exceed the effective range, the power is immediately attenuated to almost negligible.

Perhaps this is the use of heat as a bullet, a special physical performance.

Zhou Yan is not a scientist, so he has no interest in asking why hot bombs behave like this, for him, he just needs to figure out how to use high-energy pistols.

"A 1,000 kcal hot bomb is very powerful, so what is the power of a 5,000 kcal or 10,000 kcal heat bomb?" Zhou Yan stopped his car and came to a construction site where a subway was being repaired.

He saw the gantry, the thickness of the I-beam on the gantry was estimated to be twelve or thirteen millimeters on both sides, and the thickness in the middle was about seven or eight millimeters, all of which were made of crude steel.

Aiming at the I-beam, it comes up with a shot.

A 1,000-calorie thermal bomb hit the steel in the middle of the I-beam, which can melt through the crude steel with a thickness of seven or eight millimeters, but only a trace of it is not completely melted through.

This kind of power is simply not possible with an ordinary rifle or machine gun.

Catch up with the average sniper rifle and heavy machine gun.

Another shot hit the steel on both sides of the I-beam, and it did not melt through, probably two-thirds of the way. Seeing such a situation, Zhou Yan roughly had an accurate idea of the power of a 1,000 kcal hot bomb, which was equivalent to the power of a machine gun or a sniper rifle.

Of course, there are many types of firearms, and the power of bullets of different calibers and types is different, and it is difficult to accurately compare.

Zhou Yan just made a simple judgment based on his own cognition, and then analyzed what kind of existence a thousand kcal hot bombs could kill according to this judgment.

Turn the hot bomb standard, adjust from 1,000 kcal to 5,000 kcal.

"Smack!"

Zhou Yan pulled the trigger and hit the steel on both sides of the I-beam, and this time, the hot bomb melted through the steel without hindrance, and it melted through the steel on the left and right sides.

The steel on the left and right sides is at least twenty-five millimeters thick.

"I'm afraid that a large-caliber sniper rifle, or a heavy machine gun, is at this level...... More than that, seeing that this thermal bomb easily melts through two layers of 123 mm crude steel, I am afraid that the power is far more than that, if the hot bomb of 1,000 kcal just now, the armor-piercing effect is 10 mm, this time 5,000 kcal may be 50 mm. ”

Zhou Yan was not afraid of wasting heat and the number of shots, and did the experiment again, he found the right direction, and one shot pierced through four layers of steel, and the small hole that melted through stopped before stopping.

Added up, that's almost fifty millimeters.

"Fifty millimeters of steel, this is almost in time for a cannonball, right? It's much stronger than a sniper rifle, and I've heard that many sniper rifles can hit helicopters, and as long as my shot is accurate, the helicopter is estimated to be able to penetrate it. However, the tanks may be a little worse, and many tanks have armor of hundreds or even more than a thousand millimeters. ”

A small high-energy pistol barely feels much recoil when it is discharged, but the power it produces is comparable to that of a cannonball.

"It's a high-tech alien weapon!"

Zhou Yan clenched the high-energy pistol tightly, feeling that he was already invincible, even if the worm, spider and crab were in front of him, and if he shot it, he would have to die violently: "I still have 10,000 kcal hot bombs, if the power of the previous two hot bombs increases, does it mean that it can penetrate a hundred mm steel plate?" ”

Right now.

Under the subway station, which had not yet been repaired, there was a roaring sound from Suosuo, and then, an eight-legged crab and a spider-like giant insect rushed out of the subway station.

Behind him was a large group of zombies, crowded under the subway station, unable to climb up.

"Say Cao Cao, Cao Cao, it's a worm spider crab!" Zhou Yan stood beside the gantry, not dodging, and at this moment he was still accumulating violent emotions in his heart.

After seeing the worm spider crab, he quickly adjusted the high-energy pistol to the standard of 10,000 kcal thermal bomb.

Then he raised his hand at the worm and spider crab that had just found himself, and raised his hand to shoot it.

"Da!"

Gunshots rang out.

A 1,000-calorie hot bomb is a slight "poof", a 5,000-calorie hot bomb is a small "pop", and now a 10,000-calorie hot bomb is a crisp "click", which is not much louder than a pistol shot.

This shot.

Still accurate.

The small round head of the insect spider crab shattered in an instant, as if it had suddenly exploded. If you play it back in slow motion, you can clearly see that its head first split apart, and then in a very short time, the shattered part burned into ashes and disappeared without a trace.

Without any accidents, the worm spider crab fell.

The body is still twitching unconsciously.

Under the subway station, zombies roared.

On the road, Zhou Yan quickly walked to the insect spider crab, took out the basin, cut the joint part of the burnt head and body, and released the insect blood.

The meat of insect spider crabs is delicious, far better than the meat of insect mantis, spiny bone worms, and insect flies.

Two chelicerae are excellent materials for building iron guns, and the last chelicerae were ordered by someone else, and this time they were left to themselves. In fact, the long legs of the spider crab are also good materials, but unfortunately they are too long and too big to put there.

While recovering the resources in the worm blood.

Zhou Yan squinted his eyes and adjusted the high-energy pistol back to the standard of 1,000 kcal hot bullets, this gun will be his biggest reliance in the last days, at least for now.

"Giant Worm World...... World of Beasts...... Maybe I can explore it! ”
