Life Jump, Level Up.

Extraordinary, these two words contain not only the improvement of the level, but the comprehensive leap of physical fitness.

This stage almost represents the re-evolution of a new species from its own species.

Reproductive isolation even began to appear gradually.

Declining fertility is the best proof of this.

After all, if it is the same species, the stronger the body, the stronger the fertility should be, not lower and lower.

The stronger the body, the stronger the seeds sown and the stronger the ability to conceive.

Fertility will never be reduced or disappear as documented.

The most likely reason for this situation is that the difference in the evolutionary environment and time has caused the subtle differences in the new race.

In the case of reproductive isolation from the lower level, there is also reproductive isolation with the same level and above.

It's almost a whole new species.

Of course, there are also those who specialize in evolving fertility, such as a certain tragic wind.

Fully evolved, shielded reproductive isolation ability.

Without further ado, let's get back to business.

In their spare time to create traps, Fu Yanjie and Lin Yu once competed in the cave.

Without the use of modern weapons, even if Fu Yanjie was wearing battle armor, he was still pressed to the ground by Lin Yu and beaten.

The strength and speed contained in Lin Yu's body are almost the same as those of the battle armor, and the most important thing is that Lin Yu's reaction speed is much faster than Fu Yanjie's.

The mechanical force program loaded by the armor is quite stiff.

The most obvious thing is that during the battle, Fu Yanjie's move Lin Yu can completely dodge.

Lin Yu's move, Fu Yanjie, couldn't dodge except for resisting with his battle armor.

After all, reality is not a movie, and it can't be like Iron Man, wearing a battle armor can also enhance the speed of nerve reactions, and even dodge bullets and even missiles.

Moreover, after entering the transcendental, the power of the undead holding cold weapons in their hands even began to gradually catch up with the modern weapons in the hands of Lin Yu and the others.

The only advantage has been erased, what advantage do the two have?

The situation is getting worse and worse!

The plans made by the two slowly couldn't catch up with the changes, and after the war, one problem after another kept popping up.

Fu Yanjie suddenly had the idea of giving up the battle and directly blowing up the second half of the passage.

Lin Yu, who was standing on the side, took a sip of water, saw the worry in Fu Yanjie's heart, reached out and patted him on the shoulder, and comforted.

"Don't worry, we didn't kill them all, but we also sent them to a weakened state."

"In this state, the power they exert is less than 1/3 of the original."

"Don't say it again, you didn't see you just now."

"The so-called transcendental, is it different, wiped out by three bullets?"

"Their strength also has a limit, and it's not really impossible to destroy."

"Just be careful, and it's not a problem to kill them." Lin Yu comforted objectively.

Fu Yanjie may be able to give up, but Lin Yu can't, no matter what it is, he has to fight and there is no way out.

Half an hour of anxious waiting passed quickly.

After a brief rest, Lin Yu and the others took a large amount of ammunition and weapons.

Leaving Hall 2 again.

Push the tanker truck along the railroad tracks in the mine.

In the tunnel, the closer you get to Cave 1, the higher the temperature.

Approaching the wall, you can even see a slightly distorted scene.

This is the refraction of light produced by the high temperature baking due to the large difference between the ground temperature and the air temperature.

The rocks under your feet were still a little cool, but the temperature in the air had reached fifty or sixty degrees.

The wind blowing from the blower behind him has been converted into a heat wave when he comes to this place, and the temperature cannot be reduced much at all.

The two of them in battle armor and bulletproof vests were forced to sweat by the heat wave, and the beads of sweat kept falling down, wetting the shirts inside.

Outside the walls, most of the flames in Hall One had been extinguished, and only the sparks were still close to the top of the cave, tumbling around.

The rough wall in front of it was burned by half an hour of high temperature, and the women's wall was full of cracks.

When you get a little closer, you can only feel a heat wave hitting your face, and the temperature is at least hundreds of degrees Celsius or more.

Seeing the wall, Lin Yu stopped pushing the cart, parked the tanker truck a little farther away from the wall, and tightened the oil cover on the car, lest any sparks suddenly fly over and float in.

Pull off the two nozzles on the spout and attach them to a large jug at the back.

Faced with this situation, the two had already prepared.

The mine was set on fire, burning at high temperatures, and it was inconvenient to dissipate heat.

After the flames are over, the temperature absolutely soars.

The skeletons can take advantage of the residual heat of the fire to face the hundreds of degrees of heat attack, but the two of them can't face Baidu's high-temperature defense like the skeletons.

The temperature was enough to burn them and keep them from going up the fence.

Flesh and blood are less resistant to the damage caused by the flames.

So they prepared a large water storage tank filled with water to cool the wall.

Lin Yu turned around and installed the two water cannons, and stuffed one in Fu Yanjie's hands.

"Come on, have fun!"

Fu Yanjie took the water cannon, grasped it, temporarily put aside the worries in his heart, and agreed with a smile: "Okay!" Ha ha! ”

Lin Yu and the two turned on the machine in the car, held the water cannon, changed to a more handsome posture, and turned on the switch in laughter.

A man's happiness is so simple, since he can't solve the difficulties, then he can only comfort himself in the difficulties.

The water gushing out of the water cannon crossed a distance of more than ten meters and poured onto the wall of the cave entrance.

"Snort~~"

After being scorched by the flames for half an hour, the scorching wall suddenly made a sneering sound as soon as it came into contact with the cold water.

A large amount of water vapor rises from the place of contact.

Immediately after that, the wind from the mine blew to the side of the skeleton.

The temperature in the tunnel dropped at a rate visible to the naked eye, and in less than two minutes, the temperature dropped by half, and the air became a little wet.

Lin Yu and the others took the water cannon and carefully poured the wall twice, until the wall no longer emitted mist and steam.

Turning off the water cannon, Lin Yu leaned in, and cautiously reached out and touched it.

It's still a little hot, estimated to be forty or fifty degrees, but it's already in the range where the body can touch it normally.

It was acceptable, so the two stopped reworking, turned back to get their weapons and equipment, and climbed the wall again.

On the other side of the wall, in Mine No. 1, the flames were still burning everywhere, and the air was still quite hot.

However, the momentum of the flame has decreased a lot, and without the replenishment of subsequent fuel, the flame on the ground is only more than 30 centimeters high.

It is a far cry from the original two or three meters of flame length when the fire was first set on fire.

Under the scorching firelight, the mine showed Lin Yu and the two of them a strange beauty.

The white bones piled up on the ground were thirty or forty centimeters high, and all the bones were burned through, leaking a scorching red light, like a burning charcoal fire, showing a scorching red color.

The walls around the hall and the outer layer of the enclosure have taken on a semi-glazed shape under the scorching flames.

The overall look is smooth and bright, and the subtle gold and elements contained in it have also been refined and inlaid on the surface of the glass.

Against the backdrop of the firelight, it reflects a seven-colored light.

The top of the cave, for some unknown reason or something, is all black and gray, mixed with gold inlaid on it and broken glass-like rocks, which are like stars in a summer night against the background of the underground fire.
