This iron gate is extremely thick at first glance, and it is difficult to rely on its own strength to penetrate it.

Fortunately, there is a cross-shaped hole in the iron door, which seems to be the keyhole to open the door.

But Queen Qingling only gave him a map, and did not have any keys.

Shisu said in his heart, it seems that there must be a key here, but I don't know where to hide it.

Yu Feng pulled out his long sword and gestured, found that he could insert~ it, and said, "Look at me destroying this lock." ”

Shisu hurriedly shouted: "Don't move, there may be a mechanism inside, and if it is broken, it may not be able to open." ”

He took out a map and compared it to it, and found a small man with a bow and arrows drawn here.

Could it be a hint that it should be opened by shooting arrows with a strong bow?

Ziyun asked, "Young Master, what should we do?" We don't have the key to open the door. ”

"I'm afraid the key is inside the wall, Fengfeng don't mess with the iron door. Zi Su shouted a little late, Yu Feng touched a certain mechanism as soon as he touched the iron door, only to hear the sound of swishing, and a row of feather arrows shot quickly from the wall, there were dozens of them.

"Brother Zisu, don't worry, this arrow can't even break my body protection qi. Sure enough, when those feather arrows hit Yu Feng's body, they were stopped by a fiery red qi and fell down one after another, and Yu Feng was not injured at all.

Protecting the body is powerful, Ziyun is extremely envious, which also promotes her enthusiasm for practice, she knows very well that if she wants not to become a burden to the young master, she will always follow him, and only by making continuous progress can she do it.

Shiso could see at night, and although it was dark in the corridor, he had no problem looking at it.

After careful inspection, he noticed that there was a stone slab on the wall to the right of the door that was slightly darker, and he tried to press it hard, and the stone slab was pressed into the wall with a click, and then he heard the sound of zaza, and a stone drawer popped out of the wall on the left, and in the drawer was a longbow and a long arrow.

Shiso picked up the long arrow and took a closer look, and found that the arrow of the long arrow was cross-shaped, consistent with the hole, which showed that it was the key to the iron door.

He shook the arrow in his hand and said, "The key has been found, and this arrow is." ”

Yu Feng smiled and said: "Brother Zisu is smart, he found the mechanism so quickly, bring the arrow, I'll insert ~ go in and try it." ”

Zi Su thought that if the strength was enough, maybe he could open the iron door directly with an arrow in his hand, and Yu Feng's strength here was undoubtedly the most powerful, so he handed over the long arrow and said, "Feng Feng, then you can try it." ”

However, with Yu Feng's strong strength, he inserted the arrow almost very hard~ into it, but the iron door did not move.

"How can this be!" Yu Feng didn't believe in evil, inserted it again, and tried to rotate, but found that it couldn't be turned at all.

"Fengfeng, don't force the turn, it is estimated that the mechanism in the iron door has not been opened, you are careful to break the arrow if you turn it so strongly. ”

Yu Feng let go of his hand and asked, "Then what should I do, I have used so much effort that the door still can't be opened." ”

Shisu smiled and said: "Isn't there a bow, it is estimated that you want to use the bow to shoot arrows ~ into the hole." Yun'er, it's up to you next. ”

"No problem, young master, leave it to me. Ziyun is a master of using a bow, she picked up the longbow and found that it was quite heavy, it was a strong bow, she put on this cross arrow and tried it, looking for a feeling.

During the attempt, she kept backing away, too close for the arrow to shoot.

A big fireball suddenly appeared in Yu Feng's hand, illuminating the iron door very brightly, and asked, "Ziyun, can you see it?"

Ziyun nodded and said, "Fengfeng, it's okay, you can see it." ”

She walked to the end of the road, took the right head, her right hand was like holding a mountain, her left hand was like holding a baby, the bow was like a full moon, and the arrow was like a meteor.

The force was so great that the arrow almost didn't reach the top. Then I heard the sound of Zaza, and the iron door finally opened.

"Good shot!" Shiso sighed.

It turned out that this iron gate weighed 10,000 catties, and no one opened it all year round, and many places had rusted, and it was necessary to use such a strong impact force to shake the mechanism and open it.

Yu Feng just used an arrow to insert ~ to try, relying only on wrist strength, of course, not as strong as the arrow shot by the big bow, and the strength was not enough to open it.

"Let's go, you guys go in first. ”

After the two women entered the door, Shisu reloaded the long arrow and pushed it into the wall, then walked into the iron door and closed it again.

After closing the door, Shisu carefully observed the terrain in front of him.

This is a stone room with carved beams and paintings, but the items inside are messy, and there are dead people's bones everywhere, Ziyun was accidentally mixed with Sensen's white bones when she walked, and almost fell into the pile of bones, which scared her a lot, "Ah!" exclaimed, and threw herself into Shiso's arms.

Zi Su hugged her and asked, "Yun'er, what's the matter?"

Zi Yun replied with a bitter face: "Young master, it's nothing, it's just stepping on the bones of a dead man." ”

Yu Feng grinned and said, "What is there to be afraid of the bones of the dead, these are the things I see the most in the dungeon." ”

Ziyun shook her head and said, "Your heart is so big, can I compare with you!Young Master, where is this, how should we go?"

"This should be a stone chamber in the battle between good and evil, you see, the long swords in the hands of these two corpses pierced each other's vital points, and they should have died together. ”

Ziyun frowned and said, "These bones are not beautiful at all, young master, let's leave quickly." ”

Zi Su was actually not interested in these white bones, he smiled and said, "Okay, you come with me." ”

Out of the stone room is the marble corridor, and there are wall lamps on both sides of the corridor.

"The passages in the front and back and left and right seem to be similar, this hellish place is evil enough. ”

The underground palace is indeed worthy of the name of the labyrinth, which is crisscrossed by corridors, there are many forks, and each stone chamber looks similar, if you don't have a map, it is easy to get lost in the corridor.

What's more, in addition to the intricate terrain, there is also a maze array here, which is the terrifying part of the underground palace. Once you fall into the quagmire of the maze array and can't get out of it, you will always be with these white bones.

Fortunately, on the map given by Qing Ling, there is a special way to break the maze array that enters the entrance of the second-floor palace, and Shisu is not worried about this.

Along the way, the most in the road is still the white bones of the forest, some of the white bones still have carrion on them, it can be seen that the time of death is not long, the underground palace attracts a large number of warriors and tomb robbers, but there are very few that can really be gained.

After turning left and right, the three of them finally came to the maze array at the entrance of the second floor.

You can't take a wrong step here, if you make a mistake, the mechanism will be touched, and then the entire stone chamber will sink, and no one knows how many floors it will sink to.

Shiso thinks it's a bit like an elevator.

"Three on the left and four on the right, two in the front and one in the back, you two follow in my footsteps, don't make a mistake. ”

When the three of Shiso walked according to the secret, the entire stone chamber shook for a while, and then the whole fell down, and the three of them were in a state of weightlessness for a short time.
