At this moment, Yun Yi has also come to the front of these palaces, and when he looks at them from a distance, he doesn't think they are big, but when he looks closely, he is completely different, and he sees everyone levitating around them, just like an ant compared to a big palm.

From these palaces, Yun Yi could clearly feel that an ancient aura brewed from a long time emanated from those palaces, and the aura was thick and huge, enough to drown the people around them.

Looking at the eighteen palaces shrouded in light, everyone understood that there must be treasures in them.

So some people couldn't bear it anymore and rushed to one of the palaces first, but naturally they were blocked by the light mask and couldn't enter the palace.

Yun Yi smiled slightly when he saw this, it seems that if he wants to enter the palace, he must meet the relevant conditions.

Sure enough, a man entered the mask without resistance, and swiped the door with a card, and the palace door immediately opened, and the man stepped into it in one step, and then the door closed automatically.

"Why can't we enter, but the man can?"

"I just saw a card in the man's hand, is it because of the card?"

"Quite possibly!"

Seeing someone enter the palace, some of them whispered. And secretly wishful thinking. The people who can come here are not ordinary people, and they are very wise, rather than letting them grab the card holders now, they are more willing to wait for those card holders to get the treasure out before grabbing it.

They understand that the treasures in this palace are not so easy for card holders to obtain, and they may have to go through a test to get them.

"Let's go, let's go in too." With that, Yun Yi flew towards a palace. Seeing that there was a spear-shaped mark on the front of his card, Yun Yi thought that this should be the opening of the palace with the spear-shaped mark.

Each palace has a different weapon mark above the door frame, which is exactly eighteen kinds of seals.

After a while, Yunyi flew into the light mask, and the crow was stopped from the light mask.

"Master, I can't get in, I'll wait for you outside." The crow said to Yun Yi with a depressed expression.

"Okay, then I'll go in myself." Yun Yi turned around and said, then turned around and flew to the palace door with a spear-shaped mark, took out the card and swiped it on the door, and then the palace gate opened violently, and then the ancient access control IC card automatically dissipated into a point of light in Yun Yi's hand.

Yun Yi was not surprised by the disappearance of the card, and the same was true of other people's cards, and then Yun Yi walked into the palace without hesitation.

As Yunyi entered, the door closed automatically, and no one could see what incredible things would happen inside, except for Yunyi and Zeta. Originally, Zeta should have been blocked out of the light mask, but Zeta had expected it and entered the particle state mode in advance, so he was not blocked by the light mask and followed Yun Yi into the palace.

"Little brother, it's really not simple, you can actually get an access card." In mid-air, Yiyun looked at Yunyi who had entered the palace, and said with envy.

After Yun Yi entered, a man armed with a metal rod and a scar on his forehead also entered a palace with a stick sigil.

After the scarred man entered the palace, a large man armed with a sledgehammer also entered a palace with a hammer mark. After that, many people entered one after another, until the eighteen palaces were occupied.

In fact, Yunyi's card is different from others, there is no mark on other people's cards, only Yunyi's card has an imprint. Except for the palace with the spear-shaped imprint, they can choose one to enter at will for the rest of the palaces, while Yunyi can only choose the spear-shaped imprint palace to enter. In the same way, everyone's card will disappear after entering the palace.

In the palace.

A huge wall of fire blocked Yunyi's front. This wall of fire was automatically released from the ground after Yun Yi entered the palace, and the whole body was golden yellow, and if you got a little closer, you could feel a scorching breath, as if you were in a furnace.

Yun Yi looked at the wall of fire and found that it could pass from above, so he jumped slightly, wanting to use the thruster to fly through it. As a result, the thruster on his back did not respond, and he thought that there should be an equipment jammer in this place.

And this wall of fire is obviously a test, if it can fly over, it will obviously not achieve the effect of the test, Yun Yi thought.

"I'll go to the front to help you find the way, and I'll go first." Zeta said to Yun Yi, a little curious about what treasures existed in this palace.

"Okay, there you go." Yunyi replied casually.

Seeing Zeta enter the particle state mode and easily pass through the wall of fire, Yunyi was a little envious.

Then he took a closer look at the wall of fire, and decided to rush through it, he was protected by a battle suit, and he thought that he should be able to pass through this wall of fire, so that he would not be too embarrassed. Immediately, his body moved, and he rushed into the wall of fire as fast as he could.

After a thought, Yun Yi successfully passed through the first wall of fire, and did not suffer much damage, except that the tips of his hair were slightly burned. Standing in the fire-free zone, Yun Yi exhaled softly, thinking that this wall of fire was not as difficult as he imagined. Then he looked at the second wall of fire in front of him, and thought about it for a while, this wall of fire is probably not as simple as two, and the difficulty is likely to gradually increase as the more walls of fire pass through.

Staring at the second wall of fire, Yun Yi put on a running stance, then held his breath, moved his body, and rushed over again. After two breaths, Yunyi passed smoothly again. This second wall of fire, Yun Yi could clearly feel that it was twice as thick as the first wall, and even the temperature had increased a lot.

Next, Yunyi successfully passed the third, fourth, fifth, sixth, and seventh fire walls.

From this seventh wall of fire, Yun Yi could clearly feel that the temperature of this wall of fire was already very frighteningly high, far from being comparable to the previous walls of fire. The wall of fire was sixty-four times thicker than the first wall.

It's terrible to think about it a little and feel like you're going through it. It's like being grilled alive on the grill, and I'm almost ready to cook.

Yun Yipan sat in the fire-free zone, rested for a while, and let the battle suit on his body cool down. If there is no protection of the battle suit, I am afraid that Yunyi is already ripe at this moment.

Between every two walls of fire there is a fire-free zone for the testers to rest. Exhaling deeply, Yun Yi slowly stood up and stared at the eighth wall of fire in front of him, a little hesitant in his heart.

However, thinking that he had the power of regeneration, as long as he was not burned to ashes, he could recover, and his eyes showed a look of determination. Holding his breath, he pulled down the mask from his helmet, summoned up his courage, and rushed into the wall of fire without hesitation.

The moment he burst into the wall of fire, the flames drowned it out in an instant. Bursts of burning sensation came from all directions, enveloping Yunyi tightly.

Fortunately, Yunyi is not an ordinary person, the speed of running is as fast as lightning, and after a few breaths, this feeling of getting off the oil pot gradually subsides. Yun Yi stood in the fire-free zone and bent over, his hands on his knees, panting heavily, the mask on his helmet had already been opened.
