The battle between the two clans has almost entered the white-hot stage, and the army of desolate beasts is still an army of desolate beasts, but a third of the tens of thousands of mechanical envoys have been buried here forever.

Blood not only stained the earth red, but also the dark clouds, and the snow and ice falling from the ground seemed to be soaked red by the river of blood of the earth.

In addition to the roar of the desolate beast, only the roar of the desolate beast is left, as for the human mechanical envoys where they still have the strength to shout and kill, their throats are almost hoarse, and their vocal cords are also scarred, which is not a big deal for them as mechanical envoys, but now every trace of energy in their bodies is precious, and repairing the vocal cords is no longer in their plan.

Killing any beast in front of them was their only goal, and at this time they could only fight against the beast, because the remaining mechanical envoys were almost instinctively waving their weapons at this time, and those who did not have weapons were only unconsciously waving their fists.

The oil is gone, the ammunition is gone, the food is gone, no, it's just the ammunition, the food is not exhausted, because there are countless dead beast corpses around them!

Ru Mao drinks blood!

In order to kill the beasts as much as possible, they gave up reason!

For the sake of the home behind them, they gave up the human form!

For the sake of victory, they gave up everything!

There was a more or less tyrannical look in the eyes of every mechanical envoy present in the battle, and blood invaded their eyes little by little.

At this moment, they are beasts, fierce beasts, tyranny fills their bodies and minds, and only killing is their only thing.

Life was long gone when they turned mad, and even if they lost their hands or arms, or suffered shocking injuries, they would bite off a piece of flesh from the beast!

Tragic and great!

Seeing the machines in the battlefield fall one after another, Li Yu and a dozen other people who were in the stronghold watching the outside world also felt grief, but they felt more despair.

There were dozens of fourth-level mechanical envoys at the beginning, but now there are only a dozen or so left, who can know the despair of this war better than them, when everyone they are present is dead, that is when this stronghold is destroyed.

None of them wanted to, but they didn't have a choice.

"It seems that the old decay also needs to go, Li Yuzi, I didn't expect that the final confrontation between me and you didn't come, but we ushered in the army of desolate beasts, it's really better to be counted!"

Suddenly, an old voice sounded among more than a dozen people, but there was no trace of age in the words, only pride and ease.

"Dou Lao, you ......"

"Okay, Li Yuzi, now is not the time for us to grind, after I leave, if we win, remember to give my Dou family a little help, I'm leaving!"

Li Yu looked at the figure in front of him who was leaving freely, he didn't know what he felt in his heart at this time, maybe there was indeed an entanglement between him and Dou Lao like a sea of blood feud, but at this moment, he faced an old man who was about to die, but he couldn't raise a trace of hatred.

"Wild beast!"

His fists were clenched, and the green tendons stood out, but he couldn't do anything about it.

Except for Li Yu, the rest of the fourth-level mechanical envoys are no better, and they also know that they can't change anything, and even they will be next.

It didn't take long for a devastating explosion to appear on the screen in front of Li Yu and the others, and the incomparably terrifying energy spread from one point to the surroundings, and the range of several thousand meters directly became a vacuum zone, where was the rear of the army of desolate beasts, where most of the fourth-level desolate beasts were located.

The fourth-level mechanical envoys present didn't know how many of those fourth-level desolate beasts had died in this explosion, but they all knew that Dou Lao had sacrificed.

Regardless of whether he was a fourth-level mechanical envoy who had been embarrassed by Dou Lao's forces, he couldn't help but feel a burst of pathos in his heart at this time.

Maybe Dou Lao's forces used to have a bad reputation among the strongholds, but at this moment he was a hero, a hero of the human race.

"Dou Lao is gone, he is a hero!"

A fourth-level mechanical envoy spoke in an authentic voice, maybe his voice was not very loud, but in this quiet environment, it seemed so loud.

No one responded, but there was a hint of red in the corners of their eyes.

Dou Lao was the first fourth-level mechanical envoy to break into the rear of the desolate beast army alone to self-detonate, and he bought precious time for the human camp, as well as a lot of breathing time.

Because the army of desolate beasts retreated, they gave up their prey in front of them, and with a roar from the rear of the desolate beast army, they directly gave up the killing of human mechanical envoys.

However, the red-eyed mechanical envoys were unwilling to let go of the retreating beasts, and they chased the beast army with red eyes.

The army of desolate beasts didn't care about the pursuit of human machines, they just kept retreating.

In the end, the army of desolate beasts left behind tens of thousands of desolate beast corpses and disappeared in front of the eyes of the human mechanical envoys.

Seeing that the desolate beast army disappeared outside the stronghold, Li Yu and the other fourth-level mechanical envoys were not the slightest happy, they knew that the retreat of the desolate beast army this time was only temporary, and they would eventually come back again, not to mention that this time the human stronghold could be described as a heavy loss.

The fourth-level machine sacrificed five or six tenths, the third-level machine sacrificed four-eighths and five-eighths, and the third-level and lower machines sacrificed eight or nine out of ten.

It was simply the heaviest sacrifice ever made in the history of a human stronghold.

"Let's go, let's go and welcome the return of the hero!"

Li Yu's heavy voice sounded in the room.

The rest of the fourth-level mechanical envoys didn't do much and directly followed Li Yu's footsteps.

At this time, the door of the stronghold to the outside world had already surrounded countless ordinary people, and they had no words, so they stood at the door, their eyes fixed on the closed door in front of them.

Creak~

The closed door slowly opened, and the first person finally appeared in front of all the ordinary Rao.

Just as everyone wanted to cheer, the figure of the mechanical envoy behind the first person also appeared in front of them, and their cheers that wanted to break out were directly stuck in their throats, and no matter how hard they tried, they couldn't shout.

As more and more mechanical envoys entered the human stronghold, the ordinary people who were watching were also red-eyed and gave way little by little, this time not because of the level gap between the mechanical envoys and ordinary people, but because of the sacrifice of the mechanical envoys, and also because of the ordinary people's heartfelt awe of the mechanical envoys.

At this moment, they finally understood what a mechanical envoy was, and what the mission of a mechanical envoy was.

Every ordinary person present endured the crystal that was about to slip from their eyes, and unconsciously made the etiquette they had learned from books with their hands on the mechanical envoys who carried three or four corpses behind them, which they had never seen the real face of, and it was also a ritual they had never done.

In a moment, they did it, even if their etiquette was not standardized.

They recognized the mechanical envoys, and the last barrier in their hearts was completely gone!
