The moment he saw the exit, Song Rui was overjoyed, and the nerves that had been tense relaxed a little, and he glanced back at Zebra, in case he could pull him if he didn't have a problem with this way of traveling.

But the moment he turned around, he saw that Zebra's eyes became extremely terrifying for a moment, Song Rui was stunned, keenly aware of something, suddenly there was a gust of wind howling behind him, he didn't have time to look back behind him, his body instinctively acted, turned sideways suddenly, and avoided to the side.

But his movements were still a little slow, only to see a fist, rubbing his throat through, although it did not rub his bones, but the fist wind was too strong, still cut off a layer of the entire neck bone, if it was a human, it was estimated that he would be killed by one blow.

It turned out to be Nitro, who had been guarding the perimeter of the stone tower! It was supposed that the collapse of the stone tower had caused the terrifying aura to dissipate, and the Nitro was guarding outside, and it happened to be in a position at this time.

The white bone powder rose, and the blue light in Song Rui's eye sockets suddenly condensed, and the blue light contracted like a needle, and his mind became extremely calm in an instant. Song Rui didn't even take half a second to feel distressed, he reacted quickly, pushed and sent his right hand, moved the wine jar held between his arms to his left hand, and then put his five fingers together like a knife, and inserted it three inches below Nitro's ribs.

Song Rui's reaction was extremely fast, and his counterattack was also very sharp, and even Zebra was a little surprised.

Because of the pursuit of maximum lethality, this Nitro rushed extremely fast, but at this moment, it was too late to change its moves, and the passage space was narrow, and it was blocked from tossing and turning, so it could only withstand Song Rui's blow.

"Huh!" Song Rui's fingers are still very sharp, not inferior to most weapons, although Nitro's defense is high, but it has an advantage in breaking the surface with points, and it is to attack the opponent's shortcomings with his own strengths, Song Rui's hand knife made a meritorious blow, and it pierced through Nitro's hard skin and muscles, causing it a lot of trauma.

At the moment of Song Rui's attack, Zebra was stunned for a moment, but he quickly reacted, and another sonic missile was issued, this time with a slightly smaller diameter, just enough to envelop Nitro without hurting Song Rui.

Song Rui did not take advantage of the victory after the victory, which was also out of trust in Zebra, so he hit the right shot, pulled back sharply, slid down against the wall like a monkey, and quickly distanced himself from Nitro.

At this time, the sonic missile also happened to hit Nitro.

The lethality of sonic missiles mainly relies on the high-frequency vibration of sound, causing great damage to the target, when ordinary matter is hit, its own tiniest molecules will vibrate with it, and finally the whole substance collapses from the molecular level, shatters and dissipates, just like the bluestone that was hit before, it will disappear directly as if it was vaporized in an instant.

However, Nitro did not dissolve and dissipate like ordinary matter, but was pushed upside down by the impact of the sonic missile, and the strong defense of this creature can be seen.

Of course, it's not unscathed, if it's a complete state of Nitro, naturally it won't take Zebra's attack in his eyes, but the bad thing is that it's bad, it has injuries under the ribs!

The principle of the short board of a barrel is like this, how much water a bucket can hold depends on the board with the shortest plank. And the wound under Nitro's ribs is like a short board in defense, a very small gap, but the effect it plays at this time is huge. Although Nitro's own defenses were strong, this small wound was something it could not defend against now, so the tissues around the wound began to collapse due to vibration, and gradually spread into the body.

The great pain was accompanied by an incomparable sense of crisis, which made the Nitro scream for a long time, if the sonic missile lasted a little longer, it would probably hurt its internal organs, and it was already relenting at this time.

And here Song Rui and Zebra did not take advantage of the victory to pursue for the time being, their first problem is to come out of this passage, the passage is narrow, which is extremely unfavorable for combat, Song Rui is an assassin type is okay, but Zebra's attack range is too wide, and it is easy to cause accidental injuries if you are not careful.

This time it was Zebra who rushed in front, he had a sonic attack, attacking and defending in one, and it was very convenient to advance and retreat.

Song Rui touched his throat...... That is, the position of the neck bone, and his hands were suddenly stained with a layer of bone meal, and he felt that he might be suffering from cervical spondylosis at a young age (fog...... It's really a sad story, first a broken arm, and then a cervical spine problem, this trip to the underground palace is really unfavorable!

Thinking like this, Song Rui's speed did not decrease, and the stone tower soon couldn't hold on, and the passage under his feet was the same.

Fortunately, the speed of the two was fast enough, and the fight just now was said to have been very long, but in fact, in a split second, Song Rui and Zebra finally got out of the passage before the stone tower completely collapsed.

At the moment when they went out, the entire stone tower collapsed, and there was only a large pit tens of meters deep left, and the bluestone inside was shattered into slag, Song Rui was in a cold sweat, if they were below, hundreds of thousands of tons of bluestone would be pressed down, and it was estimated that no number of lives would be enough to fill.

Thinking like this, Song Rui felt a little pity, they didn't take down the drawings of the first and second floors and take them away, and now they are all buried under hundreds of thousands of tons of bluestone, and they knew that they would be torn off.

Looking around, the collapse of the stone tower did not affect the construction of the underground palace, which also made Song Rui breathe a sigh of relief, otherwise, it would be impossible for the two of them to continue to run.

I didn't find the Nitro around, I don't know if it was because of the injury and fled, or if it was peeping in the dark, Song Rui didn't feel the gaze of his gaze, he looked at Zebra.

"It's not nearby, it must have been gone." Zebra's sonic map didn't reveal the whereabouts of the Nitro, and he snorted coldly, obviously extremely unhappy with the creature Nitro, "Let's get out of here." ”

Song Rui nodded, although this trip to the underground palace was full of twists and turns, and he almost lost his life, he finally gained something, and it was far beyond expectations.

Although it seems that there are more doubts now, ...... Take your time, translate those few texts, and you will always find some answers.

Song Rui pressed the backpack on his chest, and tightened the wine jar that was blocked in the crook of his left arm, the sense of happiness in his heart was not too strong, although he was injured a lot, but with milk, then everything would not be a problem!

"By the way, Zebra, how are we going back?" Song Rui suddenly remembered this question, when they entered the underground palace, they did not arrange a way to retreat...... That's big enough.

"Huh? I don't know! Zebra's response was the same as always...... The feeling of what is going on with me.

Song Rui black line, I don't know if communication can be used, if not, then it's really blind.
