Suddenly, Zheng Lin's mecha was also bombarded from the side by those monsters, and the engine also began to be damaged, and the power was obviously insufficient, and Li Yangyi directly used his battle armor to stand behind Zheng Lin's mecha, so as not to let the Immortal Great Wall No. 3 break away from the three-person team.

Rumble!

At the last moment, Xiao Ran finally fired, this time he directly knocked down a layer of monsters, and finally broke out of the Koboyi belt.

Li Yangyi and Zheng Lin behind them also rushed out, but the mecha was greatly damaged, and they didn't have much ammunition left, and the consumption of the mecha's power was beyond their imagination.

Xiao Ran said, "Hold on a little longer, we are about to enter Neptune's atmosphere." ”

After about half an hour of continuous flight, Xiao Ran suddenly said, "We went around Neptune's orbit, and finally we met at the other end." ”

Only in this way will they be able to destroy the enemy to the greatest extent.

Suddenly, the three mechs parted ways. After entering the atmosphere, they changed the mecha's propulsion to low-temperature boosting, and by absorbing the gas on the surface of Neptune's atmosphere and converting it into power, they obtained the maximum speed of the explosion, which could not only save energy, but also prevent the high temperature from detonating the atmosphere.

And after the thousands of monsters behind him saw the three mecha rushing into the atmosphere of Neptune, they didn't think much about it, and in an instant, a black tide divided into three strands and chased after the three people.

Neptune's atmosphere is 80 percent hydrogen, 19 percent helium, and trace amounts of methane. In such an environment, as long as there is enough temperature to produce an explosion, its power is naturally not to be underestimated.

And Neptune also has its uniqueness, he has the largest storm area in the solar system, which can reach more than 2,100 kilometers per hour here, and such a powerful air flow storm naturally caused extremely active atmospheric activity, so it had a huge impact on Xiao Ran and others.

And Xiao Ran has been kept in the middle atmosphere of Neptune, which can ensure that it can cause the largest scale of lethality when the atmosphere is detonated, but in the same way, such a low-altitude flight will face great danger, and the slightest carelessness will be the end of the plane destruction and death, and there is no possibility of escape.

Xiao Ran found out through the system that there were at least a million black-armored monsters following after his mecha. In the face of such a large-scale black-armored monster, Xiao Ran's nerves were extremely tense, and he had to concentrate on it without the slightest confusion.

Two hours later, Xiao Ran and Li Yangyi were 10,000 kilometers apart, and when their communication equipment contacted again, Li Yangyi immediately asked about the situation.

Xiao Ran had his own way, so he didn't suffer substantial damage, but Zheng Lin was a little uncomfortable, because he was attacked in space before, so the speed was much slower, and he was caught up by those black-armored monsters a few times when he circled the atmosphere of Neptune, but fortunately, the atmosphere storm of Neptune was extremely fast, which allowed Zheng Lin to escape.

"We're going to meet in half an hour, and when the time comes, I'll detonate the atmosphere."

Xiao Ran said decisively.

Li Yangyi and Zheng Lin nodded, they were not reckless, and their state was not very good at the moment, so it was most appropriate for Xiao Ran to do this task.

When Xiao Ran saw the mecha of the two, he instantly pressed a button, and with the press of the button, a hole suddenly opened on the side of the mecha, and a slender missile of about three meters slipped out.

This is a remotely controlled nuclear bomb, containing an energy of about 300,000 tons, originally to open up the earth's crust and rock layers, but now it can only be used here, and once such a nuclear bomb is detonated, the explosion range may be thousands of kilometers, and the power is not limited to the energy contained in it.

After Xiao Ran put down the nuclear bomb, he instantly reversed his orbit and directly broke through the atmosphere.

At this moment, the tide of the three monsters converged into an extremely large black tide, and at this moment, it had the momentum to swallow the heavens and the earth.

Seeing this scene, Xiao Ran gritted his teeth and pressed the timer start button, and the nuclear bomb left in the atmosphere instantly began to time.

"Three!"

"Two!"

"One!"

These three seconds seemed to be the longest three seconds they had ever experienced, and almost at the moment when the countdown ended, Xiao Ran and the three of them all held their breath.

Rumble!

Suddenly, a burst of flames bloomed in front of Xiao Ran, and the powerful airflow was instantly blocked, even the storm stopped at this moment.

Then Neptune's atmosphere was detonated, and a powerful energy spread in all directions, instantly engulfing hundreds of millions of black-armored monsters.

The heat wave stretched for thousands of miles, and everywhere Xiao Ran could see, there were flames churning. At this moment, it was as if Neptune, which had been frozen for billions of years, was ignited.

The energy generated by the explosion is enough to destroy one-fifth of life on the Earth's surface, but on Neptune, that energy is nothing.

Looking at the endless flames, Xiao Ran's mecha was instantly pushed out of Neptune's gravitational range by the powerful heat wave.

I don't know how long it took for Xiao Ran's vision to return to normal.

Xiao Ran checked the mecha, and there were indeed a lot of situations, all parts of the mecha were affected by the powerful impact, and the attack system was already close to paralysis.

Soon, Li Yangyi's avatar appeared in the lower right corner of the screen.

"Xiao Ran, how are you?"

Xiao Ran nodded and said, "I'm okay, let's go back immediately now." ”

So the three mecha were ready to leave, and at this time, Xiao Ran suddenly caught a glimpse of the powerful flames in the direction of Neptune, which was instantly extinguished, although this explosion would not completely ignite Neptune, but it was absolutely impossible to be extinguished so easily.

For a moment, Xiao Ran's heart was shocked, and he suddenly had an ominous premonition.

"Oh no, let's go, those things aren't completely worn out!"

After hearing the news, Li Yangyi and Zheng Lin's faces were also very ugly, but they did not hesitate at all, and immediately moved forward at full speed.

Although the atmosphere that detonated Neptune killed hundreds of millions of black-armored monsters, this was far from enough, and in the face of the black-armored monsters that swarmed again, Xiao Ran and they could only choose to escape.

Their three Immortal Great Wall ships have reached their limit, and they can no longer carry out the previous wave of operations, and now their mecha ammunition depot has only a small amount of ammunition left, and they are completely unable to resist, if they are caught up again, it will only be a dead end.

The three Immortal Great Wall raised the acceleration to the extreme, and in the face of the powerful oppression of almost more than a thousand accelerations, the faces of the three of them were all very iron-blue, and only Xiao Ran, who was relatively strong, could still make some movements.

"It's too far away from Earth now for us to send a distress signal, so we can only watch our lives during this time."

Xiao Ran began to operate the console, he turned on the measuring instrument, and began to measure the distance from the earth, as long as they arrived at Jupiter, they could get in touch with the earth, and when the time came, with the support of the earth, they would have the possibility of escaping.

From Neptune to Jupiter, a journey of nearly four billion kilometers, Xiao Ran and others could only rely on themselves during this time.

Facing Zheng Lin, whose engine was damaged, Xiao Ran and Li Yangyi took turns to push, and the danger they faced was also extremely high while maintaining ultra-high speed. If something goes wrong, it will turn into a speck of dust in the universe in an instant.

At a distance of four billion kilometers, Xiao Ran had been running for twenty hours, and when they saw the huge earthy yellow planet, the whole person was excited.

Xiao Ran immediately pressed the emergency distress button, at this speed, the fastest should be able to get help when they arrive at the asteroid belt.

Looking at the endless black-armored monsters behind him, Xiao Ran and the others' hearts were still very heavy.

If humans can't kill it, these things will cause even more terrible disasters to mankind.

Maybe some people will condemn Xiao Ran for luring wolves into the house like this, but from Xiao Ran's point of view, who is willing to give up hope of life. Taking a step back, even if Xiao Ran's actions are indeed inappropriate, but in the face of the endless starry sky, there will always be a day when he will have to face those mysterious existences, which human beings cannot avoid.

In the Americas, in a primeval forest, a three-headed pterosaur is lazily crawling on a cliff, even though its size has shrunk to twenty meters, it is still very large.

In the past six months, its cultivation has still recovered almost, and it has probably reached the strength of the mid-planetary level. However, it was not happy at all, because it wanted to leave the earth, but due to Xiao Ran, it could only stay here, which made it very depressed.

Just as its three heads were basking in the sun, it suddenly felt something, and immediately raised its head to the sky.

Immediately he roared angrily, and suddenly the heavens and the earth trembled, and the whole forest immediately fell silent, and one monster after another crawled on the ground, trembling.
