Small farmers dominate the desert island

Chen Yu replied without hesitation: "I knew you would ask this question. The reason is actually very simple. The tomb is sealed and there is no oxygen in it."

"After the stone door is opened, the air will circulate and oxygen will get in. Only with oxygen will the oil lamps burn."

"What is oxygen?" Tong Yan asked curiously like a baby.

Chen Yu stared at Tong Yan with a smile for a long time, not knowing how to explain to her what oxygen is.

After thinking about it, he joked, "Oxygen is a gas that can be burned. It is hidden in the air. To put it bluntly, it is the farts of humans and animals. Farts can also be burned."

"Ah?" Tong Yan thought Chen Yu's nonsense was true, exclaimed and asked again: "Then why can't you smell the smell? As far as Yan'er knows, farts stink."

"You don't understand this. As the saying goes, loud farts don't smell bad, and stinky farts don't sound loud. The stinky farts are all sucked up, leaving only the loud farts that don't stink and turn into oxygen in the air. Don't Entanglement, entanglement is a disease that needs to be cured, hehe."

Chen Yu had a smirk on his face, fooling Tong Yan with his mouth full of running trains.

"Okay, Yan'er is not entangled anymore!" Tong Yan nodded slightly, and then stared at Chen Yu with Qiman's adoring eyes.

"Brother Yu knows a lot. He is the smartest man in the world."

Chen Yu nodded with a smug smile, but said in his heart: Brother not only knows a lot, but also can fool around, hehe.

After waiting outside the Shimen for a while, Chen Yu found a few football-sized stones and threw them into the tomb passage to ask the road test agency.

There was no abnormal reaction in the tomb passage, so Chen Yu led Tong Yan in with confidence.

Entering the tomb passage, Chen Yu kept a special eye on it, and used the crystal sword to draw the stone wall of the tomb passage.

Even if they encountered some phantom formation in the ancient tomb, they could still follow the traces drawn by the crystal sword to get out.

The stone on the stone wall of the tomb passage is very special, and the crystal sword makes a dazzling sound of "chacha" when it is scratched on it.

This sound also produced an echo effect, which sounded particularly terrifying in the dark forest.

Tong Yan timidly grabbed Chen Yu's skirt, looked around nervously, and said in a trembling voice: "Brother Yu, why don't we go out, Yan'er doesn't want a baby anymore!"

The previous excitement was swept away, replaced by endless fear, Tong Yan was really scared.

Chen Yuyi was bold and nervous and said: "Don't be afraid, it's okay, I have brother here, I will ensure that you find the treasure and go out safely."

"Then, well, Yan'er trusts Brother Yu and listens to Brother Yu."

Tong Yan replied timidly, but still clung to Chen Yu's lapel.

The tomb passage was not very long, only 80 to [-] meters, and the two of them came to the end while talking, and a huge iron gate blocked the way.

Tong Yan wanted to persuade Chen Yu to quit, but seeing him looking at the giant iron gate with great interest, she swallowed the words that came to her lips.

The huge iron gate about three feet high is dark red and looks very old and thick, revealing an indescribable sense of historical vicissitudes.

Chen Yu looked around carefully, then stared at the huge iron gate for a while, hesitantly ordered Tong Yan to use internal breathing instead and hide behind him.

Be careful with the Ten Thousand Years Ship, Chen Yu is really afraid that the tomb behind the big iron gate is sealed, and poisonous gas will gush out once it is opened.

After careful consideration, Chen Yu still decided to open the tomb door.

He himself is invulnerable to all poisons, and Tong Yan has a red skirt and precious clothes to protect him, so he will not be in too much danger.

For the sake of safety, Chen Yu asked Tong Yan to stay away when he opened the tomb door.

"Brother Yu, you must be careful, if it doesn't work, let's give up."

Tong Yan backed away, and reminded Chen Yu that she really wanted to quit right away, and she didn't want any more treasures.

"Well, don't worry, it's alright."

Chen Yu turned around and smiled confidently at Tong Yan, "Brother is the god of war, the smartest man in the world, brother is omnipotent, hehe."

Chapter 1113 Back off!

Chen Yu's confident smile gave Tong Yan endless confidence, she nodded fiercely, "Yes", and then took out the dragon and phoenix swords and held them tightly in her hands.

At the same time, she also sensed the situation around and behind the tomb door with her powerful energy, and it seemed that there was no danger.

She nodded fiercely at Chen Yu again, "Brother Yu is the best man in the world, no matter what decision you make, Yan'er will support you."

"Good girl, look!"

After helping Tong Yan, Chen Yu stopped delaying and pressed his hands on the huge iron gate.

The iron door panel was extremely cold, and Chen Yu felt a chill from the bottom of his heart. It could be said to be truly icy cold.

With enough strength, Chen Yu vigorously pushed the huge heavy iron gate.

The iron door made a "creaking" sound, and he slightly opened a gap.

An extremely cold breath rushed towards his face, Chen Yu hurriedly retreated, turned around and ran towards Tong Yan.

As soon as he turned around, he was shocked to find that the huge stone door at the exit of the tomb passage had been closed at some point.

"Damn, this is inviting you into the urn!"

In a hurry, Chen Yu pulled Tong Yan and ran towards Shimen.

It was too late, the giant stone gate weighing several tons had been tightly closed, and Chen Yu couldn't open it even with all his might.

Not only that, but the material of Shimen is extremely tough, and the crystal sword can't even leave a trace on it.

"Brother Yu, what should we do?"

Tong Yan asked with a trembling voice.

"It's okay, don't be afraid." Chen Yu comforted Tong Yan softly, but couldn't close the stone door, and turned to look at the iron door that was pushed open a gap.

He muttered softly: "It seems that the owner of the tomb is too lonely and wants to keep us with him."

The stone gate was difficult to open easily, and then closed quietly. Chen Yu believed that the mechanism in this ancient tomb was very powerful.

If you can't open the stone gate by brute force, you can only enter the tomb to find the mechanism hub and destroy it.

"I want to trap brother even if I get caught in a small trap, but there is no door."

Trapped for the time being, Chen Yu didn't show a little panic, but laughed very conceitedly.

Tong Yan smiled and said, "Brother Yu is the best man in the world, let's go, let's go in and hunt for treasure."

As she spoke, she took Chen Yu's arm affectionately and walked towards the tomb door.

Chen Yu withdrew his arm, gently hugged Tong Yan into his arms, stopped and said, "Wait a little longer, we will go in after the filth inside is gone."
