After only a few steps, these robots encountered a situation in which there seemed to be a wall in front of them, and no matter how hard they tried, they could not move forward half a step.

"What kind of weapon is this?" Captain Charlotte looked at Mordin, puzzled.

"This should be a super quantum strong interaction force field, extremely tough, no one can destroy it, no, you can try!" Mordin sat down beside Lin Xuan to check his condition.

"Stand back!" Captain Charlotte swung his fist back, and all 11 robot warriors stepped back 20 meters.

"Fire!" He gave an order, the heavy sniper in his hand fired first, the ceramic warhead flew towards Lin Xuan with a speed of Mach 10, and the other robot warriors also fired at the same time, the armor-piercing projectiles fired by the bazooka roared towards the invisible wall of air in front of him, and several soldiers shot while shooting, = and threw out a few infantry grenades.

Now it's hilarious, these lethal weapons with high-speed kinetic energy and lethality exploded 20 meters away from them like a burst of fireworks, shrapnel cremation splashed, and the shock wave from the explosion of the drugged warhead sent ripples on the gas wall like stones thrown on the water surface, but all the attacks were blocked out of the gas wall without exception, and even the smoke from the explosion failed to break through the wall a little bit!

This group of unbelieving robot warriors bombarded indiscriminately for 5 minutes in a row, and the situation did not change at all, and the wall was still unmoving, extremely stubbornly blocking in front of them.

Captain Charlotte was confused by this situation, what the hell was going on?

"Why did you stop?" shouted Mordin, from inside.

"What spell are you using here?" Charlotte looked at him quizzically.

"This may be a kind of space barrier, which can isolate the back and forth of objects, I have been studying here for three years, and I have not found a good way to break through it, you can try again, let me observe its vein, in case it is cracked today, then I will definitely invite you to come in, thank you well, I promise to invite you to eat fish!" Mordin raised the two fish in his hand and said with a serious face.

"Spatial barrier?" The expression on Charlotte's face revealed that he couldn't understand at all, this kind of spatial barrier could only appear in the light network, how could this thing appear in such a place?

What to do now? If we continue to attack this invisible wall in front of us, we don't know when we will break it, and if we give up, it is obviously impossible, because it is very clearly stated in the combat manual that we must not give up the attack until all methods have failed.

"What else is there to do?" He began to look at his surroundings, "Is it possible to dig a tunnel underground?"

He thinks that this method is feasible, since it is a spatial isolation, it should be isolated from the soil on the ground, but now it seems that the invisible wall does not form an invisible trench on the ground, which means that there is no spatial isolation in the soil.

"Ground-penetrating missile preparation. He commanded.

Three robot warriors remove a ground-penetrating missile from the mech.

"Aim for the root of that wall and fire!"

Three missiles whizzed out and hit the ground of the space separation wall, "Boom!" After a few loud bangs, several deep craters were blown out of that place. But to Charlotte's despair, the debris and smoke from the explosion were still blocked by an invisible wall.

It seems that the wall has been extended underground!

"Heaven and earth can't do it, so it seems that there is no way?" Captain Charlotte was a little at a loss.

He began to think about retreating.

But he felt that something was wrong!

"How's it going? Can't you retreat?" Mordin's voice came again, and he seemed to be able to read his own thoughts.

"Huh...... Isn't that right!" He suddenly realized the doubt in his heart just now, "Since it is a spatial isolation, it should be that all objects cannot penetrate, but why can sound and light penetrate it?"

Everything that is accustomed to is often the least suspicious, as soon as he came in, he saw Lin Xuan's state, and Mordin's appearance was not abnormal at all, and the sound was transmitted through the air, and the air waves would not be isolated, what kind of space barrier is this?

"Isn't this what Mordin calls spatial isolation?" he expressed deep suspicion, "this Mordin is known for his trickery in the light web, could it be that he is lying to himself?"

He looked at the "wild man" with long, tousled hair with suspicious eyes.

"Do you doubt my claim?" Mordin read through Captain Charlotte's mind again, "Light and sound can be transmitted through, what kind of spatial isolation is this, right?".

Charlotte felt that this Mordin was simply a god, and he knew what was going on in his heart.

"yes, can you explain?" he simply admitted.

"Would you believe if I told you that this spatial wall is wise?" Mordin asked, staring at him.

"What are you kidding, the spatial wall can still produce intelligence?" exclaimed Charlotte, who thought that Mordin was simply crazy, that the spatial wall was just an object, and that it could be as intelligent as a human being.

"And what are you? Aren't you also assembled from a pile of steel and chips, and do you still have a computer program to generate your thoughts?" Mordin asked rhetorically.

"We are different, our ideologies already exist!" Charlotte felt that Mordin's views were simply an insult to himself, how could he say that he was made of a pile of steel and chips, and that he was a thoughtful, conscious, intelligent robot!

"It's in the optical network, you are originally a virtual existence, in case the optical network is closed, you will naturally disappear, don't think that you are any different from a bunch of objects!" Mordin said coldly.

"You're wrong, we already existed before the optical network appeared, but the appearance of the optical network provided us with additional space for activities, just like we are now transmitted from the optical network to your world, without this pile of machines, we still exist in this world!" Charlotte argued unconvinced, "Unlike you humans, when the body dies when the body dies, the soul perishes with it!" He laughed at him instead.

"Actually, you're only half right!" Mordin corrected, "We humans are actually the same as you robots, after our bodies disappear, the soul is indeed gone, but it doesn't mean that there is no longer in this world, you have the light network, and the world before the light network, we also have it." ”

"Where are you, too? Is it in heaven?" said Captain Charlotte, "your souls all come from heaven and return to heaven after death, these are the gods and Buddhas that you humans believe in!"

"Looks like you know quite a bit!" Mordin chuckled dryly.

"Alright, let's get down to business, how about we work together?" he suddenly suggested.

"Cooperation, cooperation with you?" Captain Xia didn't understand what he meant.

"Yes, work with me, and together we will break down this spatial barrier!" Mordin said clearly.

"Hmm...... You didn't make this thing?" Captain Xia was confused by him.

"I've been locked up here by this space barrier for three years, and it's now our common enemy, right?"

"Yes, so to speak. "Captain Xia finally understood what Mordin meant, it seems that he is also trapped here, so we can consider working together.

"I agree to cooperate with you, however, our cooperation is limited to breaking the spatial barrier together, and after that, whether you are friend or foe is determined by your actions!" Captain Xia pointed to Lin Xuan who was lying there, meaning that if Mordin wanted to stop them from taking Lin Xuan away, then there would still be a hostile relationship between them.

"That's what I mean, wait until the common enemy is gone, and then we'll settle our relationship with each other!" Mordin agreed.

"Okay, how to cooperate?" Captain Xia was also relatively straightforward.

"Your fire attacks are under my command, and you have to fight wherever I tell you to, can you do it?"

"This ...... No problem, but how long do you want us to attack? Can't wait until our ammunition is all gone, you will only have the upper hand at that time!" Captain Xia was full of defense.

"Hmm...... According to my estimate, if you attack with all your strength for another 5 minutes, I will be able to break through this spatial barrier! This attack intensity, you have no problem, right?"

Captain Xia calculated, and after another 5 minutes of attack, the remaining ammunition should be more than enough.

"No problem, let's get started!" he urged.

"Okay!" Mordin didn't rub anymore, he waved his hands, and the dust on the ground was stirred up by his palm wind, forming a yellow-brown "earth dragon" in the air, and then he handed it over with both hands, and the earth dragon flew towards the space barrier, Mordin's ten fingers were linked, and the earth dragon was attached to the transparent and invisible qi wall, outlining a strange figure.

Captain Xia took a closer look at this figure and felt that it seemed a little familiar.

"Isn't this the Tai Chi Yin and Yang Fish diagram that often appears in the Chinese Taoist school?" He finally recognized the figure.

"There are still two fish missing!" Mordin said, picking up the two fish from the ground and throwing them far away, right in the eyes of the two fish in the Taiji Yin Yang Fish Diagram.

Then he sat down on a rock, crossed his legs, let go of the knack on his thighs, closed his eyes slightly, tucked his abdomen and chest, and began to meditate.

"......," he whispered.

With the rotation of this figure, many bright patterns suddenly appeared in the invisible wall behind the figure, and the patterns were complex and intertwined, as if it was like a huge machine, undergoing complex operations.

"Just fire at the brightest of patterns, with a lot of fire, and don't be reluctant to run out of ammunition. He admonished.

"Okay! aim at the brightest pattern and fire with all your might!" Captain Xia ordered.

"Dada...... Bang bang ......" The weapons in the hands of the 11 combat robots rang out, and one after another the bullets dragging the flames fired at the invisible wall of gas, and the explosions continued one after another, stirring the cave into a mess!
