Seeing this scene, Song Ziyu wanted to come forward to help.

But then more and more silicon-based lifeforms burst into the wall...... In such a situation, even if Song Ziyu wants to kill, he can't kill it.

"Hurry up, otherwise it's too late, Song Ziyu, let's go!" Xiao Ai looked very flustered, and kept beckoning Song Ziyu to run for his life.

Song Ziyu clenched his fists so much that he clattered, but finally chose to give up.

It can't be helped, sometimes it's really the situation that is stronger than the person.

Song Ziyu followed Xiao Ai to escape for his life towards the complex underground corridor.

The Lower City Vault was once likely to be a key base project for human development in this plane, but it was not yet completed, and there were many unfinished projects underground.

These passages have now become life-saving passages!

Because the corridor is too complicated, it gives everyone the opportunity to hide and escape.

……

Song Ziyu followed Xiao Ai through the complex passage for a while, and successfully got rid of the pursuing silicon-based life army.

"Great, be safe for the time being......" Before Xiao Ai's words fell, a terrifying metal claw pierced through the wall and grabbed Xiao Ai.

This sneak attack is completely extremely covert and very easy to be overlooked, but Song Ziyu did not.

Song Ziyu, who was engrossed, happened to see the metal blade breaking through the wall, so he also drew his knife and slashed it.

The two metal blades collided together, and Song Ziyu cut off the claws of the silicon-based lifeform, and at the same time, he pulled out his teeth and saved Xiao Ai.

The silicon-based lifeform that had been cut off from the metal arm did not feel any pain, but instead jumped out and broke through the wall and grabbed at Song Ziyu.

Song Ziyu was furious, thinking that he was really bullied by dogs in Pingyang, and it was really too much for such a thing to dare to suck his hair in front of him.

Without thinking too much, Song Ziyu made a brazen move and stabbed directly into the core of the silicon-based lifeform.

This knife directly made the silicon-based lifeform rest.

Song Ziyu pulled out the knife and showed a hint of happiness on his face.

Grandma's, I can't handle that special body called Agares, can't I kill an ordinary silicon-based lifeform?

Thinking of this, Song Ziyu couldn't help but look around happily.

"Let's go!"

Xiao Ai exclaimed: "These Sartyrs are all connected with each other, if you kill one of them, the other Sartyrs will know immediately, if you don't leave now, they will catch up immediately." ”

Hearing Xiao Ai's words, Song Ziyu remembered this stubble, so he didn't dare to delay any longer and followed Xiao Ai to transfer.

But the situation is just as Xiao Ai said, the death of a silicon-based life directly exposed the coordinates and location to other silicon-based lifeforms, so a large number of metal monsters chased and killed Song Ziyu.

The situation has become very dangerous!

Song Ziyu had no choice but to kill, in a vain attempt to kill a bloody way.

But as several silicon-based lifeforms were hacked to death, more and more metal monsters moved closer.

Of course!

These are not the deadliest of all!

The deadliest of all is ......

Agareth appeared.

Holding the scepter, Agareth approached Song Ziyu's location step by step, surrounded by several silicon-based lifeforms.

Song Ziyu did not dare to contact and fight with Agares, so he could only escape.

But at this time, Song Ziyu's heart has sunk to the bottom, because he and Xiao Ai have been chased to the point of panic!

Both Song Ziyu and Xiao Ai knew that it was only a matter of time before they were blocked by these monsters.

At this time, Song Ziyu was ready to fight to the death, and was ready to desperately kill several metal monsters.

"I know a place where I can hide, you come with me!"

Xiao Ai, who was racking his brains, seemed to think of something, grabbed Song Ziyu and drilled into the direction of a corridor.

Then, Song Ziyu came to a strange closed room.

There is a lot of clutter piled up here, most of which is discarded and useless.

Song Ziyu stood in the room and looked around curiously: "Where is this?" ”

Xiao Ai wiped the sweat on his face and said, "This is a place where debris accumulates in the lower city, and no one usually comes to ......."

Xiao Ai couldn't speak halfway through his words, because Xiao Ai found that Song Ziyu was staring at something in the room.

It was a skeletal arm, lined up in a pile of miscellaneous items in the middle of the room, as if it were an inconspicuous specimen.

But......

Song Ziyu felt an inexplicable heartache.

Seeing this arm, Song Ziyu's whole person was like being struck by lightning.

"This ......"

Song Ziyu couldn't help but exclaim.

Xiao Ai looked at the arm and said, "Don't make a fuss, this arm professor has also studied for many years, and he has always thought it is strange, but in the end, he didn't come up with a reason, so he chose to give up...... Hey, what are you going to do? ”

Song Ziyu trembled and stretched out his hand to grab his arm!

The moment his arm touched the bone arm, the bone arm disappeared in an instant!

See this scene!

It was Xiao Ai's turn to exclaim.

Because......

The professor did a lot of tossing when he studied this arm bone, and it can be said that various means were used, but there was no way to cause any damage to the arm.

Xiao Ai even thought for a moment that this arm was an alien!

But now......

When Song Ziyu touched this arm bone, the indestructible arm bone turned into ashes directly.

What's going on?

……

Xiao Ai was shocked, but Song Ziyu felt that it was too normal.

Because, this arm is simply your own!

The reason why the arm is not ancient is entirely because of the power of the crossing bracelet to protect it.

Now that he himself has appeared, the crossing bracelet seems to sense Song Ziyu's existence, so he gave up his arm that turned into dry bones.

Song Ziyu picked up the crossing bracelet from the ashes, and there was a feeling of old comfort.

The crossing bracelet that had lost its attachment to the arm bone lay quietly on the ground flickering with fluorescence, as if waiting for Song Ziyu.

Song Ziyu trembled and picked up the crossing bracelet.

The moment your fingers touch the bracelet, the whole room glows.

At this moment, Xiao Ai was stunned.

"It's really you, old man!"

Song Ziyu put the bracelet on his wrist, and immediately, a long-lost voice sounded in his head.

Song Ziyu was stunned for a full three seconds before he reacted.

That's right!

I didn't dream myself!

At this juncture, he actually recovered the crossing bracelet that had been lost for several years.

So what are you waiting for?

Song Ziyu greeted Xiao Ai and said, "Come here!" ”

Xiao Ai didn't know why, but she still got closer to Song Ziyu.

Immediately, Song Ziyu hugged Xiao Ai and gave the order to cross the bracelet. 33

That's right!

Song Ziyu knew that he couldn't do anything in front of him, and wanted to escape in this way.

However, when the green light flashed, Song Ziyu was dumbfounded.

I actually appeared in a completely unfamiliar place.

Some people died, but not completely......
