The flame rushed directly towards the soldiers in front of the door, and when they left the door, the flame was no bigger than a basin, but by the time they reached the soldiers, the flame had risen to more than 2 meters in diameter!

In the face of this sudden attack, those soldiers did not have the slightest psychological preparation, and just watched as the flame reached in front of them, and then exploded violently!

Rumble!

The six soldiers in front of them were completely engulfed by the exploding flames in an instant, and they didn't even scream and then disappeared, but the flames did not disappear or stop.

The soldiers who were ambushed on the left and right sides were horrified to see that the terrifying high-temperature flames that had burned six of their colleagues into charcoal in an instant quickly split into countless fiery snakes, winding towards them!

The movement speed of those fire snakes was even faster than the previous fireballs!

Before he had time to dodge, several fiery snakes climbed up the legs of several soldiers, and immediately, starting from that part, a fierce flame erupted, spreading quickly along the legs of those soldiers to his whole body.

The reaction of the soldiers was not slow, and as soon as the fire snake touched their bodies, they bent down to slap the flames, but when they found that the flames were spreading too fast, some of them immediately lay down on the ground and began to roll, trying to extinguish the flames in this way, but instead of decreasing, the flames were getting stronger and stronger, and the more and more severe pain in their bodies told them that this trick was still useless!

When the other soldiers saw this, they were even more surprised, and hurriedly dodged these fire snakes with all their might, and at the same time, the weapons in their hands were no longer aimed at any door, and all of them were used to deal with those fire snakes.

Dangdangdang!

The sound of countless energy rays hitting the ground sounded, and they were pleasantly surprised to find that those fire snakes could really be dispersed with weapons, and immediately attacked more and more vigorously, but no one noticed that at the same time as they were dealing with the fire snakes, from that door, a cloud of dust was scattered.

The dust did not fall when it was scattered, but flew up as if it was being supported by some force, and scattered in all directions.

Soon, the dust had already walked to the heads of those soldiers, and at this time, the dust was already many times more than when it was first scattered.

The next moment, it was like rain, and the dust fell down one after another.

"Die!" A soldier shot out several energy rays in a row, completely dispersing a fire snake, but he suddenly felt a pain in his cheeks, and subconsciously raised his hand to wipe it, only to see that there was a trace of blood on the glove, and at the same time, he finally noticed the dust falling from the sky!

You know, this is already a test area, it needs to be absolutely clean, and it is impossible to have so much dust, so he instantly understood that this dust may be the same thing as those fire snakes, but at this time he has been shrouded in dust, and it is too late to dodge!

A dense snort sounded, and countless dust fell on him, each particle of dust contained extremely powerful power, and it was easy to erode the combat uniform on his body, and immediately after, the severe pain that was definitely not weaker than being burned by the flames entered his brain!

Just before he lost consciousness, he saw more dust fall on the bodies of his other colleagues......

Just when the dust and the fire snake began to flank and eat away at those soldiers, Lao Huo and Lao Tu walked out of the door, since they had been discovered, the two of them simply no longer changed their appearance, but returned to their original appearance, seeing that there were still a few enemy soldiers who were not dead, the two of them did not manage it, and walked straight to the passage to the upper level.

Behind them, the last few soldiers finally couldn't resist the simultaneous attack of the fire snake and the falling dust, and died a miserable death.

"This ...... This ......" is still in the monitoring room, Director Brad witnessed all this, subconsciously opened his mouth wide, and was speechless in shock.

And the young man beside him was much calmer than him, and shouted: "Hurry up and turn on the alarm!" Highest danger level! ”

The staff sitting in front of the monitoring desk didn't care who gave this order at this time, and slapped the alarm button with a movement, and in an instant, in the three sphere buildings of this underground research institute, the piercing alarm bell rang at the same time!

Lao Huo and Lao Tu had already come to the place where the upper floor was connected to the two sides at this time, and when they heard the alarm bell, the two of them only frowned slightly.

Lao Huo asked, "One side?" ”

"Okay." The old man nodded dryly, turned and walked towards the sphere building on the left.

The location of this underground research institute is too hidden, if it weren't for their people to find out some news, plus there is a pervert of Pitznok, it is almost impossible for anyone to find here, I don't know if this is the reason, so that the number of soldiers guarding this research institute is not too much, with the strength of the old fire and the old earth, even if you act alone, as long as you are not stupid enough to walk into the encirclement of the enemy, there will be no danger.

Of course, the fundamental reason for separating the two sides is that they want to obtain the enemy's research data faster, otherwise, once the enemy finds that there is no way to take the two of them, maybe they will really destroy the research data in a ruthless way, which will be troublesome.

And just as Lao Huo and Lao Tu began to speed up their movements, another person came to the dense forest above this underground research institute.

The path he traveled was different from that of the old fire and the old earth, but it had the same effect - he dodged all the surveillance and traps, and soon he was in front of the tree that was the entrance.

The man was none other than Pitznock, and although he said he was waiting for the group to finish his mission, he actually left a mark on the young men after leaving the building, and came here.

To be honest, he was more worried about this side than the tasks of those young people, because from the information he had received, what was being studied in that institute was likely to change the entire situation of the war and the direction of several countries in the future.

"This is it." Standing in front of the tree, Pitznock muttered, though he didn't have the skills of the old-earthed, but he could find the entrance more accurately than the old-earthed.

"Those two guys are too slow, haven't they done it yet, have they encountered a powerful enemy? Or is it something else? Pitznock muttered to himself in confusion as he began to raise his hands up and down at the entrance.

Just a few minutes later, there was only a soft sound, and the entrance opened in front of Pitznock!

However, at the same time, a huge figure swooped out from inside!

Pitznock was stunned, subconsciously dodged, dodged the pounce, and at the same time the soft sword was already in his hand, however, before he could attack, the figure had already fallen to the ground with a pop!

This made Pitznock also stunned, gave up the idea of entering the underground research institute, came to the huge figure that had fallen to the ground and had passed out, squatted down, and muttered, "What is this......
