After the stone gate was blown open, the King Kong cannon rushed in first. Raising the rifle is a burst of strafing.

I eagerly followed in, but found that there was an empty space in front of me, there was no threat, within a hundred steps were all flat bluestone ground, fifty or sixty meters in front of me a pile of white bones faintly appeared, a hundred steps away began to appear fog, visibility was extremely low.

"What are you fighting?" I asked, shouting at the Vajra Cannon.

"Knock on the mountain and shake the rabbit, scare it first. "The King Kong cannon lowered the rifle.

"Very well, your purpose has been achieved. I shook my head helplessly, this guy's previous shuttle made our already tense nerves tense to the extreme in an instant, he scared the rabbit or not I don't know, anyway, he scared us.

"Fan alert. "The Vajra Cannon didn't hear me, and waved his hand to signal the twelve mercenaries to stay on guard.

Naturally, I won't complain about the Vajra Cannon's method at this moment, because the previous explosion must have awakened the tomb protector beast in this level, and it doesn't matter if he puts two more shots.

After the completion of the fan-shaped alert, I first checked whether my aura could be used, and when I mentioned the aura, I found that the aura was blocked, and the reason why the aura was blocked was because of the lack of Kun Qi necessary to cast the aura, our aura can be subdivided into two aura, Qiankun Yin and Yang, when casting a spell, the two auras must be combined into one to make the aura, this situation is similar to the positive and negative poles can only be discharged after they contact each other, and the current situation is like the two poles lack the negative poles. The reason for this is most likely that the ground of this level is paved with some kind of material that has the ability to block the qi of Kunyin.

I don't know what is laid under the ground, but I think the biggest thing is probably a large amount of iron, because of all the metals known so far, iron is the only one that blocks yin and yang.

"Ye Aofeng, is there any iron in this level?" Thinking of this, I turned my head and shouted at Ye Aofeng who was not far away, he was born with a golden life, and he was the most sensitive to this kind of metal.

"No!" Ye Aofeng's answer refuted my guess.

"Old Niu, be careful, we can't use aura. "I shouted a warning at the King Kong Cannon.

"I've known for a long time, what should I do now?" King Kong Cannon asked for orders.

"Go ahead carefully and don't go into the fog zone. "I took the lead in walking towards the pile of bones not far away, except for the clear area with a diameter of less than 100 meters at the entrance of the stone gate, all the other locations are shrouded in thick fog, where this fog comes from we don't know at present, so naturally we don't dare to enter blindly.

Everyone cautiously followed me forward, and after a few steps, an accident happened, and suddenly there was a clicking sound in the empty level, the sound was very rapid and very crisp.

I clenched my fists and waved my arms to signal everyone to stop, and instead began to frown and look for the source of the sound, there was only one possibility that there was a strange noise in the level, and that was that a mechanism had been activated. I don't know if the mechanism was activated by the Grave Guardian or unconsciously triggered by us, and I don't even know what type of mechanism it is.

The sound of the click soon changed, no longer crisp and rapid, but became slow and dull, it took a long time to hear a serious creaking sound, this situation reminded me of the old clocks at home, at the beginning of the winding is relatively easy, the winding is very easy, the winding sound will be fast, and when the string is almost full, the resistance will increase relatively, the twisting will be slow, and the winding sound will be dull. If the traps in the level were similar, it would have reached full firing by now.

Because the level is very empty, it is difficult to accurately judge the direction of the sound, but even so, I determined that the location of the sound was on the left stone wall through the technique of earth hearing, and the left stone wall was seven or eight miles away from our current position, so far away even if there was a mechanism, it should not be able to attack our location, so I thought about it, and went straight to the pile of white bones not far away.

Coming to the side of the white bones, the first thing I found was the delicate lead box, the lead box is about thirty centimeters long, only ten centimeters wide, in a standard rectangle, I looked down and picked it up carefully, and found that the four sides of the lead box were engraved with the Dharma name of the four ancestors, and the left and right sides were the Yin and Yang Taiji pattern, according to the size of the lead box, it should be the one that stores the anti-heaven artifact, in addition, the weight of the lead box is not very heavy, far less than the pure lead of the same volume, which shows that the thing stored in it should not be big.

"Old Yu, look, these people are the nine sect disciples back then. "The King Kong Cannon stretched out his hand and pointed to the bones scattered on the ground for me to see.

I put the lead box into the backpack, looked down at the bones, the first thing that caught my attention was the various magic weapons scattered next to the bones, the magic weapons are mostly swords, there are six of them, the other three are dust, nine whips and a seven-foot anti-heaven halberd, the other magic weapons are quite intact, only this anti-heaven halberd is broken, the halberd rod is broken from the middle part, according to the traces at the crack should be cut off by some kind of thin-bladed weapon.

After observing those weapons, I moved my eyes to the white bones scattered around, the scattered position of the white bones was very messy, and far more than nine piles, I frowned and looked closely, and finally found that the reason why the bones exceeded nine piles was because these nine people were cut off from the middle part of the body, picked up a few broken bones and looked at them again, and found that the location of the broken bones was not exactly the same, those with longer leg bones and taller people were cut off from the waist, and those who were shorter were broken in the heart position.

This discovery suddenly made me frown, although the parts of these nine purple qi masters were cut off, but they were all on the same plane, that is to say, they were killed by people at one time, is the tomb protection beast in this fourth level so powerful?

"Impossible, absolutely impossible!" I shook my head and denied my thoughts, I had observed the breath of the fierce beast in this level when I had taken Penglai Jinzhi before, its cultivation was similar to the purple qi of human beings, not to mention nine purple qi masters, even if two of them did it together, it couldn't withstand it. In addition, the bones of these nine purple qi masters are scattered more than ten meters apart, and they should have walked side by side back then, how could the tomb guard beast kill them all at once, besides, this level is to block the aura, and the one who blocks the purple qi master will definitely block the tomb guard beast, and it is impossible for the tomb guard beast without the aura to kill so many purple qi masters at once, and after thinking about it, I feel that the only reasonable explanation is that it is not the tomb protector beast that will kill these nine purple qi masters, but some kind of mechanism in the level.

At this moment, a squeaky sound suddenly came from the stone wall on the left, followed by a subtle and lingering sound of "Zheng~~~!"

Even if we can't use the aura in this level, the hearing of our cultivators is still far beyond that of ordinary people, and before the sound can be heard, King Kong Cannon and I were the first to notice and let out two roars of warning.

King Kong Cannon shouted "Squat down!"

I shouted, "Lie down!"

Although those mercenaries don't know why, the blood of the knife over the years has greatly increased their reaction speed, and they made corresponding moves at the same time that King Kong Cannon and I shouted.

Almost at the same time, a golden light that was almost imperceptible to the naked eye flashed above us, and after the golden light, blood splattered, red and white, and the two mercenaries who obeyed the orders of the King Kong Cannon were all cut off by half of their heads without exception, except for the King Kong Cannon who was fine, because he was short, and the golden light was close to the scalp after squatting.

The mercenaries, who were lucky enough to save their lives, saw that their companions were in distress and wanted to get up and go to check on the ambulance.

"Don't get up!" I shouted at them again, as I drew my seven-star sword and held it up.

Although I didn't know what the golden light that had been shaved over our heads was earlier, I could guess that it was some kind of wire that was quickly swept through with the force of stretching, and the click sound I heard earlier was that the mechanism of the stone wall on the left side was running, and the purpose was naturally to taut it and gather strength for it. And the purpose of my sword is to cut this wire, because it came from the left side, and it will inevitably go back to the left.

Sure enough, as soon as my shout came out, I suddenly felt that the seven-star sword in my hand was blocking something, and the resistance turned from heavy to light in an instant, and after the wire broke, a "whoosh!" flew out from our left and right.

"Get out!" I stood up and shouted quickly at the crowd. The mercenaries dragged the two companions who had half of their heads cut off and quickly retreated to the stone gate, and I waited until everyone retreated safely.

The crowd outside the door had already discovered what we had been going through, and when they saw us coming back with a feather in hand, they hurried over to see if we were hurt.

"It's okay!" King Kong Cannon pushed away Murong Chafeng with a worried face in frustration, he was very guilty and blamed himself for the mistake of giving the order that killed the two mercenaries in his previous order.

Murong Chasing Feng shook his head helplessly, and took my seven-star sword to observe it carefully.

"Old Niu, we are no different from them without Dao Technique, and there is only so much we can do. I reached for my cigarette and handed it over.

"This mechanism is so shady, who the fuck came up with it?" said King Kong Cannon waving his hand and baring his teeth against my cigarette.

"The principle of the mechanism is similar to the principle of the launch of the bow and crossbow, in the Qin Dynasty bows and crossbows have been common, this is not unusual, what I don't understand is what kind of material that metal wire is. I shook my head. There was a certain reason why the Qin army was invincible back then, and they used a large number of long-range archers and crossbowmen. This mechanism obviously makes use of a similar principle, and the only thing I don't understand now is what the golden wire is made of, because gold and brass are not hard metals, they can't stretch and gather momentum, and the technology of metal smelting during the Qin Dynasty was not mature, how could they have such a tough and sharp metal.

"That's not metal!" Ye Aofeng interjected expressionlessly. Although the two mercenaries who died were his subordinates, they did not cause any emotional fluctuations in his feelings.

"Not metal?" I asked, frowning.

"Absolutely not!"
