"Cheng'er, take your grandfather out of here, and leave it to us here." When Luo Yun and Mu Zhan arrived at the battlefield, the battle had already entered a white-hot state, and Mu Hai was organizing all the mecha to fight.

"Grandpa, I'll go first, and I'll come back to avenge grandpa when I bring him home." At this time, Mu Cheng's mecha was holding a green mecha that had lost his right arm, which should be Mu Cheng's grandfather Mu Zhong, and it seemed that he had lost the ability to fight. However, it is not known if he himself is injured. Mu Cheng hurriedly flew in the direction of the village with Mu Zhong, and went back to check on Mu Zhong's injuries.

Turning his gaze to the center of the battlefield, a huge octopus-shaped sea monster was fighting with the mechists, this monster had countless tentacles under its feet, and each tentacle was about ten meters long, and it waved its powerful tentacles so that all the mechists could not get close. There are even some weaker mechs who are knocked away by the tentacles of the octopus monster in one look, and although they don't suffer much damage, they are enough to be blown away by such a large tentacle.

"This is a third-level intermediate-level alien race, our most powerful mecha master, your grandfather is second-class A, my grandfather is second-class B, and your third, fourth, and fifth uncles are three second-level C, and the others are some first-level mecha masters, which are of little use. It seems that the situation is not optimistic this time. Seeing that the monster was so powerful this time, Mu Zhan couldn't help but be a little worried, and told Luo Yun beside him about the situation on the field.

"Why doesn't a first-level mecha master do much good?" Luo Yun didn't understand the reason, so he asked Mu Zhan.

"Most of the first-level mecha divisions, the model of the mecha is F500, and the weapon they are equipped with is only one kind of laser sword, and the laser sword is only lethal to the first-level and second-level aliens, and it has little impact on the third-level ones." Mu Zhan observed the battle situation while explaining to the studious younger brother.

"Is Brother Muzhan also an F500? What about my grandfather's? Luo Yun then asked again.

"Mine is also from the F series, your grandfather's should be an E-series mecha, with a laser cannon, this thing is much more powerful than a laser sword, and it is also lethal to third-level aliens, but this time it is a third-level interracial alien, I don't know what the effect will be"

"Boom." Before the eye battle was finished, a new round of attacks began again, this time they did not preserve their strength anymore, and all the second-level mecha divisions used laser cannons.

Luo Yun looked from afar, only to see that the right hand of the Mekai mecha was no longer a long lightsaber, but had turned into a dark hole, exuding a breathtaking aura. White balls of light shot out from the hole, and the target was the huge octopus sea monster.

The scorching ball of light exploded as it touched the octopus's body. "Boil, boil." Under the bombardment of the five second-class mecha divisions, the octopus let out a series of screams. Countless tentacles were blown to pieces, and flesh and blood flew everywhere, and the scene was unbearable.

Just when everyone thought they were going to kill the octopus, something unexpected happened.

I saw that the head of the octopus began to swell, getting bigger and bigger, as if something was coming out of it. Mu Hai and the others stopped attacking the octopus, and they all flew out of the octopus's attack range, cautiously observing the changes, in case this octopus monster had any powerful attack methods.

“Bong。” A loud sound rang through the sky, and the head of the octopus exploded in everyone's eyes, and a foul-smelling brown liquid splattered in all directions. A black figure flew out of it.

"Haha, haha finally arrived, this damn octopus skin is quite thick, and it has been sleepy for a whole day." A mecha composed entirely of black metal appeared in front of everyone. It was in stark contrast to all the mechs around it, and it was a little weird in the moonlight.

"Who are you and why are you in the body of an alien race." Mu Hai glanced at the black mecha, frowned, and then asked the mysterious man. On the premise of not confirming whether it is friend or foe, it is better to ask clearly.

"Hey, the people of the Mecha Alliance, were you attacking this octopus just now?" The mysterious man did not answer Mekai's question directly, but looked at the surrounding situation, and then looked at Mekai, who had the strongest combat power here, and said.

"Yes, you came out just now when we were attacking this sea monster and were about to kill it. What do you call you? Seeing that the black mystery man did not answer his question, his tone became a little heavier. This black mecha should be a D-series mecha from the point of view of equipment. The D-series mecha is equipped with a plasma light cannon, and this black mecha has a metal part similar to a missile launcher on the left and right shoulders, which is the plasma light cannon.

"It turns out that you are attacking this octopus, even if you do me a favor today, I won't kill much, and I have to rush to hand in the task. Next time, it won't be so lucky. After saying that, the black mecha quickly galloped away into the distance, and disappeared in front of everyone after a while, very fast.

Everyone who was shocked by the sudden scene did not come back to their senses for a long time, all this happened too suddenly, no one expected that a black mysterious mecha would appear from the body of the octopus. And this mysterious man even wanted to kill them. I don't know what this guy is all about.

"Big brother, black mecha." At this time, the grandfather of Mu Zhan said in a low voice to Mu Hai, who was thinking.

"It's a dark mech." Mukai seemed to realize the intention of Mulie's words and said.

"But weren't they all killed years ago, and how could they still be on this continent?" Mu Lie said again.

"This matter can be big or small, don't disclose it to anyone first, this time I go to Chongming, I will report this matter to my superiors." As if realizing the seriousness of this matter, Mu Hai didn't say anything, and then said to everyone:

"Okay, you all go back and rest, and the damaged mechs will come to me tomorrow to get the supply box." After everyone heard Mu Hai's words, they cleaned up the battlefield and went back, after all, there were so many alien crystals that could not be wasted, and the spar of the third-level octopus was taken away by Mu Hai.

"Brother Muzhan, let's go back too." If Mu Hai went back and saw that he was not in the village, he would definitely be scolded, thinking of this, Luo Yun urged Mu Zhan to go back quickly. And Mu Zhan also knew the consequences of bringing his younger brother out without permission, so he hurriedly took Luo Yun to the village.
