Seeing that the Demon Heart had regained its mobility, Lu Tianming also stopped attacking, this kind of long-range cannonball attack couldn't cause fatal damage to the Elemental Messenger at all, right? Then don't waste firepower and energy, Demon Heart thought to himself. After all, the Titan Arm is a stable mecha that tends to strength and defense, and it does not have the terrifying long-range killing ability of the Sky Shield Sentinel, let alone equipped with the Flying Snake Whirlwind Bomb, a weapon that destroys and kills.

"Hey, I saved you hard, there's no need to continue to blacken my face, right?" Lu Tianming smiled and walked towards the new mecha Despair Giant of the Demon Heart, the size of the Titan Arm can already be described as huge, but compared to the Despair Giant, it is a child.

"En......" Demon Heart squinted at Lu Tianming, his throat moved, but he didn't speak, wanting him to spit out grateful words from his mouth, it was more uncomfortable than killing him.

"If it weren't for me, you would have hung up just now." Lu Tianming was unrelenting, as if he couldn't show the meaning of his life in this world without ridiculing the demon heart.

"I didn't kill you, that's the biggest thank you." Demon Heart said coldly.

"Haha, it's the first time I've heard someone say such a thank you to a life-saver." Lu Tianming.

"I said don't interfere in my fight."

"Anyway~ At least you survived. However, your mecha is really cool, is there such a model in the solar system? Judging by your shiny power source, it seems to be a three-star X-level mecha or above. Lu Tianming asked, in fact, he must have known about the Desperate Giant, but he just wanted to hear the Demon Heart say it himself.

"The Dark Spirit Kingdom produces much stronger than your Titan Arm. If you have time to chat, pay more attention to the enemies who are recovering your vitality, but don't accidentally die. "Demon Heart Dao.

Lu Tianming didn't care at all about the disdain of the demon heart, the mecha is dead, the person is alive, who is stronger, it's useless just to look at the number, you only know after fighting.

"Yo, speaking of the enemy, you should have been able to strike a fatal blow to him as soon as you recovered, but you didn't do it."

"I don't want to take advantage of others, this is a rare opportunity to fight, the guy who can force me to use the second type of mecha, I want to share the victory with him openly. You also stopped attacking just now, proving that you are not a rat. That's why I've postponed your death until our next showdown. Demon Heart said lightly.

Lu Tianming burst out laughing: "Ahaha, Demon Heart, you are really a master of telling cold jokes, it's so funny, I'm about to burst into tears, so I have to thank you?" ”

Demon Heart looked at Lu Tianming coldly, and said in a low voice: "Now is the battle between me and him, just watch from the sidelines." ”

"En, this joke is not so funny," Lu Tianming twisted his neck, got up to himself, and didn't take the words of the demon heart seriously at all, "You are really good at scars and forget the pain, do you still want to be beaten to the ground, and then let someone save you?" ”

Demon Heart glared at Lu Tianming angrily, every word of this guy felt like he was going to provoke a war, of course, for the fact that the beginning of the matter was caused by his own arrogance, Demon Heart himself was not without the slightest awareness.

Lu Tianming is also very unhappy in his heart, no matter how strong your demon heart is, now the first person on the mecha throne is still him Lu Tianming, along the way, Lu Tianming has endured the stinky temper of the demon heart, if it weren't for Lu Tianming's good character, I'm afraid that if you change your temper casually, you will have to do it with the demon heart.

Suddenly, the surrounding atmosphere suddenly became solemn, Demon Heart and Lu Tianming both looked nervously ahead, the mecha that exuded a faint dark green luster was slowly standing up, and with a flick of his fingers, the Titan Arm and the Desperate Giant both flew up as if weightless.

For the current situation, Lu Tianming was not surprised at all, the air pressure in this gladiatorial arena had risen to an unbelievable level since he came in, and ordinary humans could not bear it at all, so as soon as he and the demon heart entered the arena, he immediately appeared in the form of a mecha.

Although the shield enveloped the entire gladiatorial arena like a transparent spherical shell, the air valve used for ventilation was not completely closed at first, allowing the Elemental Emissary to draw outside air into the shield, creating extremely high air pressure and air shock power.

The device they were talking about at the beginning was actually the air extraction device of the Colosseum, which used a high-speed air compressor to create a powerful suction force to exhaust the air from the entire Colosseum, creating an artificial vacuum environment.

If the ancient mecha in front of him, which no one knows, is driven by the power of the wind, then the vacuum environment can make his power nowhere to exert it.

The tactic was proposed by He Tianxiang and Jian Lan, and the demon heart instinctively resisted this tactic, while Lu Tianming vetoed it after a little thought.

The ability of this mecha to control the wind in front of him is obviously so strong that it is an unbelievable realm, whether the suction power generated by the air extraction device in the gladiatorial arena can match the control power of the mecha, Lu Tianming can guess without thinking about it, the suction power generated by the extraction device is definitely not comparable to that mecha, and it is difficult to say whether the air inside will be drained or a larger amount of air outside will be sucked into the room.

Withdrawing the air will inevitably cause the air pressure in the gladiatorial arena to decrease, which the opponent's mecha can instantly perceive, since the air can be discharged, it can also be sucked into the gladiatorial arena, if the extraction device is turned on, it is equivalent to opening a passage between the gladiatorial arena and the outside world, so that when this passage is crowded, the entire gladiatorial arena is in danger of collapsing.

Just in the enclosed space of the gladiatorial arena, the opponent's mecha has such terrifying abilities, once the window with the outside world is opened, the entire atmosphere will be controlled by him, and he will become even more difficult to defeat.

Therefore, it is better to completely cut off the air exchange between the gladiatorial arena and the outside world and close the air valve.

Although Lu Tianming completely closed the air valve as soon as he entered the field, at this moment, the air volume in the field was also dozens of times that of the previous one, and the air pressure was dozens of times that of the original.

At this time, Lei Zhentian was in contact with Elder Tianyu, the chief astrologer of Pluto and one of the two elders of the Pluto Alliance.

"Elder Tianfeng." Lei Zhentian smiled slightly, and said politely, although his status is higher than that of Tianfei, but in terms of qualifications, Tianzhi is the patriarch of the Pluto Alliance, and basic respect should still be given.

"The alliance leader doesn't need to be polite, if you have any needs, please command." Elder Tianfeng said happily, unlike the reverse growth of the Earth Destroying Elder, the traces of time crawled all over this clever and wealthy old man.
