Sun Xiucheng and Ethan chatted for a few words, when they heard a noise coming from inside the cave, and Sun Xiucheng immediately realized that Tony Stark had put on steel armor and was rushing outside.

Sun Xiucheng deliberately tested the power of the steel armor that Tony Stark was making now, so after putting on the helmet, he immediately walked towards the inside of the cave.

Around the corner, Sun Xiucheng saw the first steel armor made by Tony Stark, this steel armor looked very ugly, the shell was welded together with some steel plates, the helmet was like a garbage can, the arms and legs were very rough workmanship, and the whole looked extremely bloated and had no beauty at all.

After Sun Xiucheng saw Tony Stark, he didn't say a word, and rushed forward with a punch, although the steel plates on Tony Stark's body were disassembled from the weapon and were very hard, but compared with the Hardeman alloy used by Sun Xiucheng, it was not half a point.

In an instant, clear scratches appeared on the ugly steel armor, although Tony Stark was still a little unclear about the situation, but it was not Tony Stark's style to not return fire when attacked.

Tony Stark raised his arm and swept towards Sun Xiucheng violently, Sun Xiucheng, who wanted to feel the power of this set of armor, did not dodge, and in an instant, Sun Xiucheng was repelled several steps by this force.

Using superpowers to control his sound waves inside the helmet, Sun Xiucheng laughed in a processed voice: "Tony Stark is worthy of being Tony Stark, using the radioactive element palladium as raw material, making a small arc generator to power the armor, and using hydraulic devices to amplify his own power, very good, very good idea, let me try your armor again, what other functions do you have!" ”

Sun Xiucheng said, stretched out his arm, and after a "click" sound, a small missile appeared on Sun Xiucheng's arm, and then, the small missile dragged its long tail and flew straight to Tony Stark's feet, and after a deafening explosion, Tony Stark's steel armor was swept away by the force of the explosion.

After getting up, Tony Stark was not to be outdone, turned on the upper switch on his left arm, and after aiming one of the missiles inside at Sun Xiucheng, Tony Stark pressed the launch button.

Sun Xiucheng was not unresponsive to Tony Stark's attack, and after Sun Xiucheng's shoulder, a miniature laser launcher appeared, and with the assistance of Tinker Bell's calculations, it aimed at the flight path of this small missile. After the missile flew to the planned position, a bright laser flashed, and then the missile exploded into a brilliant fire in the air.

As soon as the firelight passed, Sun Xiucheng's line of sight was enveloped by more flames, and after showing the images of the outside world through infrared scanning, thermal imaging and other technologies, Sun Xiucheng found that Tony Stark was burning his armor with a flamethrower at the moment.

Sun Xiucheng was not surprised by this, raised his arm, aimed his palm at Tony Stark, a small tube appeared in the armor in the center of his palm, and after calibrating it with the help of Tinker Bell, a stream of cold liquid nitrogen gas spurted out of this small tube and shrouded Tony Stark's flamethrower.

In less than a second, the temperature in the cave dropped by dozens of degrees, and the flamethrower directly covered by liquid nitrogen directly shattered into several pieces, and those flames were all extinguished under the action of liquid nitrogen.

Tony Stark's armor is just an experiment, and the means of attack are very few, and after losing other weapons, Tony Stark can only choose to fight hard and fight only with the armor itself.

Seeing Tony Stark speeding up towards him, Sun Xiucheng suddenly dodged to the side, and Tony Stark, who couldn't react, swept and attacked on the stone wall of the cave, and his armor was also stuck on the stone, and he didn't succeed in getting rid of it several times.

After Sun Xiucheng took a few steps back, he took advantage of this opportunity to launch a few small missiles towards the top of the cave, and in an instant, the shattered mountain rocks buried Tony Stark inside, looking at Tony Stark, who only had his head leaking outside, Sun Xiucheng smiled slightly and lifted his helmet.

"Hello, Mr. Tony Stark, it's exciting to see you again. It seems that you've been doing pretty well for a while, not only building the Ark Reactor, an epoch-making portable energy source, but also conceiving steel armor similar to the mechs in science fiction. I'm a little skeptical that I made the wrong decision to save you, and maybe if you stay a little longer, you'll be inspired to make other better weapons! ”

"The way you express your joy is really special. I don't think you're here today to fight with me, or to talk to me, get me out, I haven't seen the sun outside in days, and the environment here is really terrible. Tony Stark said, and began to struggle, Sun Xiucheng did not refuse this time, under the effect of disguised superpowers, Tony Stark was soon rescued.

After regaining his freedom, Tony Stark tapped Sun Xiucheng's armor with his finger and said with a smile: "I didn't expect that there is another person in this world who thought of making steel armor at the same time as me, your armor looks pretty good, but it is much worse than the steel armor I expected, is this your research result in the past three months?" ”

"No, it took me less than three hours to make this armor, and I'm so busy that I don't have time to study it. It's you, in the past three months, this steel armor that has been researched really disappointed me, in addition to the energy is a little interesting, the power system, weapon system are very poor, plus the aiming system, precision guidance system and other aspects of the lack of functions, if I hadn't come today, I'm afraid, Ms. Pebo would have been widowed. Although Sun Xiucheng knew that the steel armor he made was not half a star compared to the steel armor that Tony Stark would make later, Tony Stark's slightly disdainful tone still made Sun Xiucheng feel unhappy, and after Sun Xiucheng listened to Tony Stark's words, he pushed back in the same tone.

"I don't think that I need your help, even if you don't come today, I can easily walk out with this set of armor on my body, those ordinary weapons have no effect on me at all." Tony Stark was clearly confident in the armor on his body.

"Of course I believe you can get out, but who knows if you will go out lying down, or if you will be escorted back by those extremists after you go out!" Although Sun Xiucheng knew that without his help, Tony Stark could escape, but when he thought of coming to help in person, Tony Stark didn't even say a word of thanks, and said that his help was not necessary at all, which made Sun Xiucheng inevitably feel a little uncomfortable in his heart.

As they spoke, the two of them had already walked outside the entrance of the cave, looked at the extremists around them who had all lost their ability to resist, and the large number of Navy SEALs who had rushed over, and Tony Stark suddenly turned on the jet device of the armor as if to prove that he did not need the help of others.

"Welcome to my escape drill!" With this sound, Tony Stark instantly flew into the air, and then plunged into the desert not far away.
