After seeing Mina rushing forward, Chen Zhi was suddenly shocked.

In the corridor in front of them, there were about a dozen guards, all of them wearing armor and holding halberds, and the aura behind them was very fierce, and they were by no means easy to mess with.

But none of these were the most terrible, the most terrible thing was that at the end of the corridor there was a stone partition with a slender metal wire attached to it, and a metal ball was strung in the middle, which was hanging in the air.

The wire was so thin that if you didn't look closely, you couldn't see it clearly, and the metal ball in the air was only the size of an egg, which was very unnoticeable.

But Chen Zhi knew the name of the metal ball, which was very dangerous, called "Goalkeeper Needle"

This "wicket pin" is a very elaborate mechanism, and the back must be connected to a slate door.

The stone door was movable and opened as soon as it was pushed, but as soon as there was the slightest sound or fluctuation in the room, the metal ball would only sense it immediately, and then make a loud sound, more sensitive than a modern monitor.

After discovering an intruder, the "goalkeeper" will shoot a large number of highly toxic gold needles from the inside of the ball, and the number of gold needles is extremely large, emitting 360 degrees without dead ends, like falling needle rain, shooting all the people around into a hornet's nest.

Therefore, those who guard the door next to the "door guard needle" must be people who dare to die~~~~

And once this metal ball makes a loud noise, everyone will know that this location has been invaded, and they will immediately seal this stone slab, and the entrance behind it will also be sealed immediately, forming a trend of closing the door and beating the dog, blocking the intruder here, and the gods can't run out.

This kind of stone gate was often used in the bunkers of the Shang and Zhou dynasties, especially in the mansions of princes and generals, and was almost a must-have, but weapon craftsmen who knew this craft were very rare, so it gradually disappeared after the end of the Han Dynasty.

However, in the Jiang Library, there are still clear records of the design drawings of this "gatekeeper needle", and there are also such facilities in some important locations in the Xiqi King City.

Chen Zhi saw Mina jumping out, and his heart was suddenly shocked, Mina must have never seen this kind of "goalkeeper pin", and it is very likely that if she rushes forward, it will touch the mechanism, and then they will not even have a way to retreat!

"Don't go ......"

Before the second half of Fat Wei's words could be spoken, Mina had already jumped out of the air, and after she jumped into the corridor, she did not land on her feet, but took advantage of the momentum to flip into the air, clinging to the rock wall like an octopus.

At this time, everyone saw that the pair of blue gloves on her hands kept floating with electric light, and the suction cups on the gloves became very large after touching the rock wall, and they were tightly attached to the rock wall.

Mina, on the other hand, moved very lightly, crawling on the top of the rock like a spider-man, without making a sound, or even dropping a single bit of dust.

I saw Mina quickly climb on the rock wall, like a spider, straight to the stone door in front of her......

Watching Mina move above, everyone's spirits were tense, and the guards below were very close to her, and if they didn't pay attention, they would notice something, but Chen Zhi's spirit was all focused on that metal ball.

Mina is a Westerner, and she would never have seen the blueprints of such an ancient mechanism in China, so if she makes the slightest sound, she will touch the metal ball, and everyone will be finished!

At this moment, I saw Mina's body crawling lightly to the top of the metal ball, a hand wearing blue gloves stuck to the roof of the shed, bearing all the weight, while one leg hung down, dexterously hooked the wire, and lifted it up, and the metal ball immediately flew up.

At that moment, Chen Zhi's whole heart was in his throat, and if he touched the metal ball directly like this, it would immediately trigger the mechanism and radiate golden needles, and Mina would definitely be the first to be beaten into a hornet's nest at that time.

But I didn't expect that as soon as the golden ball flew up, Mina quickly held the golden ball in her hand, and then, Mina's blue gloves suddenly turned red, and countless net-like lasers shot out of the gloves and passed through the metal ball, and the metal ball instantly cracked and failed.

After the metal ball was disposed of, Mina's gloves turned yellow again, and the muscles in her arms instantly swelled, and the blood vessels burst out.

Mina rolled over and jumped down, aimed at one of the guards below, and went up with a heavy punch.

Chen Zhi has tasted the power of Mina's fists, her fists are really not vegetarian, they are completely comparable to professional boxers, and the gloves that have turned yellow seem to increase the impact power even more.

The guard was directly knocked out by Mina, knocking down several guards at the same time, and the yellow gloves carried a high-intensity electric current that was transmitted to the metal armor of these guards.

After the guards fell together, before they could get up, their bodies were shaken by the strong electric current, and after a while they were all motionless.

"Oh, I'll go~~~~, this blonde girl has two hits......"

Seeing that Mina had a hand, Fat Wei turned over and jumped out, pulled out the machete of the stone control, and was about to go up to help.

However, before he could arrive, several other guards rushed towards Mina..................

These guards reacted quickly, and when they saw that the metal ball had been damaged, they immediately knew what was going on, and directly raised their spears and rushed towards Mina!

The guards were obviously alert, and when they saw that the guards on the ground were knocked down by Mina's electricity, they deliberately separated Mina's hands and trapped Mina in a corner with their halberds, holding her arms up.

Mina wanted to fight back, but these guards made moves extremely fast, and everyone could be called a master, and after a set of moves, before she could see it clearly, Mina was set up there.

"No, their power is too great, Chen! Help me~~", Mina struggled and screamed eagerly.

And at this moment, one of the guards directly picked up the halberd and stabbed it towards Mina's stomach!

At this moment, I heard a "bang~~~", and the guard was kicked out directly, hit his head on the rock wall, and remained motionless.

Mina looked up and found Ji Ying standing there, her face was calm, the long knife in her hand was not unsheathed, she grabbed a guard with one hand, lifted it high above her head, and then threw it out like a chicken!

Those guards knew that they had encountered a powerful character, let go of Mina, and quickly fled towards the stone gate, but before they could reach it for a second, they were caught by Ji Ying and thrown on the rock wall.

There was an instant silence in the hallway............

At this time, Ji Ying glanced at Mina indifferently and said coldly,

"Don't do this kind of thing again in the future, don't put the patriarch in danger......"
