Tony was touching his chin and thinking, when suddenly he saw the roots of the Iron Tree, and a flash of inspiration suddenly appeared in his mind.

Tony struggled to break off a small tree root and scanned it, and through the scanning of the Jarvis system, Tony suddenly smiled.

"Tony, what are you doing with a root?" Deadpool asked, standing as Tony looked at Tony with a very serious look.

Deadpool didn't see Tony smiling under Iron Man's armor, otherwise he would have taunted Tony, and now Tony was holding a tree root and pondering, Deadpool just felt that he didn't know what was particularly meaningful.

"Do you say these bugs are afraid of fire?" Tony said to the crowd.

At the moment when Tony's words were finished, everyone came to their senses, and Tony was analyzing whether these iron trees could burn, and if they could, then attack with fire.

"Can these iron trees burn?" Barry asked a very silly question.

"Can't burn, will Tony still say attack with fire?" Deadpool was speechless at Barry and patted him on the head.

"In that case, then prepare the Iron Tree, and let's set it on fire." The Dark Batman immediately got to work.

Everyone didn't run back to the top again, not to mention how big the iron tree on the top was, it was very difficult to pull into the crypt, and the passages in the crypt were intricate, although they didn't turn a few places, but there were 20 roads in a fork, which was definitely easy to get lost.

After a lot of work, everyone collected a large number of iron tree roots. Regardless of whether this will cause much damage to the Iron Tree, they have collected everything they can collect.

"Let's get started." The crowd looked at Tony and Cyborg.

The two of them are definitely better than the others in terms of ignition, although the likes of Dark Superman and Barry are okay. But it's not as convenient as theirs.

"Come on, I'm covered in ice, and if I want to put a bomb, it's definitely not suitable." Tony said to Cyborg.

"It's like I'm not carrying a bomb." Cyborg gave Tony a blank look, then began to stick a muzzle out of his arm.

The muzzle of the gun directly spewed out flames and burned the iron roots, but they definitely couldn't burn in a short time, and the skin of the iron roots had a thick iron element, so that the flames couldn't burn for a while.

And after burning for 5 minutes. The iron roots were finally ignited by the steel bones, and looking at the iron roots emitting black smoke, everyone immediately pushed these burning iron roots in.

With a large amount of burning iron roots fell. Everyone also watched carefully, and saw that a sharp voice suddenly sounded below, and everyone knew that these metal beetles must be afraid of flames.

And these flames are not ordinary flames, they are flames that burn from the roots of the iron tree. There are some ingredients that can cause the flame to rise sharply.

"It seems to have worked." Tony said to the crowd.

Look at the movement coming from below the deep well. Everyone guessed that the attack below had worked, and continued to enter downwards with Mo Fei as the spearhead.

This time, there were really no more insects, and the iron tree roots had formed a fire at the bottom of the burning deep well, and Mo Fei and the others still relied on the body protection sword sent by Mo Fei to carry the flames through.

After entering a straight passage, Mo Fei and the others saw a very complex karst cave, in which a large-scale base had been established, and the flashing indicator lights on the base made Mo Fei and the others involuntarily stop.

"This is definitely not a base made up by the Zerg." Dark Batman to the crowd.

If it's a zerg. This one must have been in a hive, but all they saw now was a techno-type base. And not a base created by higher beings.

"Let's take a look." Dark Superman was the first to step forward.

And when Dark Superman stepped into the base range, suddenly a large number of gaps opened on the ground, and many zergs rushed out of it.

This time, it's not just metal beetles, but also the earthworm insects that Mo Fei encountered before, as well as all kinds of insects with complex structures.

The Zerg immediately launched an attack after seeing Mo Fei and the others, and they didn't care about the strength of Mo Fei and the others, they opened their mouths and bit them over.

"Kill !!" Mo Fei's body immediately erupted with powerful sword qi and launched an attack on these zergs.

Except for the metal beetles, which can rely on their backs to defend themselves, the other Zerg don't have much defense at all, and after the open area, without the narrowness of the deep well, Mo Fei's killing becomes very efficient.

Dark Superman and others also took action one after another, only Dark Batman and Cyborg were at the rear, and everyone else rushed up to attack.

Barry and Dark Flash ran left and right, and the two of them relied on their super speed to continuously launch disruptive attacks on various zergs, playing all of them around.

After half an hour of killing, everyone stopped, looking at the insect remains on the ground, and now looking at the location of the base is not as easy as before.

"There should be someone in there." Dark Batman to the crowd.

From the moment the massive number of bugs attacked, nothing appeared in the base, and no one could guess what the situation was, but Dark Batman made up his mind.

"Is it a human or a bug?" Barry asked at Dark Batman.

"Probably bugs, highly intelligent bugs." Dark Batman said.

"It doesn't matter if he's a highly intelligent bug or not, since he dares to attack us, then he will destroy them." Dark Superman had already been annoyed by the Zerg's successive attacks, and now he directly blasted it up, punching the gate of the base.

Rumble!!

There was a loud bang on the door, but the door was not shaken, and under the powerful punch of the dark superman, it could not impress the gate at all.

"So hard? It's harder than the back of the metal beetles before. Tony said, scanning it.

"Let me come." Mo Fei raised the Green Dragon Immortal Sword, and a dragon chant resounded throughout the space, and then Mo Fei rushed up and slashed at the gate.

Mo Fei didn't know if the gate would be cut open by himself, but he had already activated the power of the Green Dragon Soul, and this time he would definitely be able to cause damage to the gate.

But everyone didn't expect that the gate suddenly opened, and Mo Fei's attack directly blasted in, and it didn't hit the gate at all, which made Mo Fei suddenly feel like he hit the air and vomited blood. (To be continued......)
