Before Chen Wangping could think carefully about what this place was.

Suddenly, a pungent smell came from the front and quickly spread around him, irritating his skin and making him feel uncomfortable.

He sniffed through his mask and found the scent had a very faint smell of rotten eggs.

"Smells like rotten eggs? Is there hydrogen sulfide evaporating in here?"

Chen Wangping cautiously put away the lightning energy, took out the mugwort fossil and placed it in front of his chest, then explored inside with a cold light.

We can’t use lightning energy anymore. If sparks occur, it will explode.

When he thought of this, his mind moved and he immediately sped up and rushed towards Tang Xihe's location.

Since there is hydrogen sulfide and he cannot use lightning energy, then Tang Xihe certainly cannot use the fire element either.

Danger!

As expected, Chen Wangping rushed forward for two minutes according to the map and arrived near the secret vault. As soon as he turned the corner, he heard a tragic cry:

"Miss, we will cover your escape. These iron lumps are too powerful."

"Miss, hurry up and leave. Once you get out of here, you can use the fire element!"

"Yes, Miss, don't die with us!"

Following the sound, they saw that Tang Xi and the twenty or so city guards around him were all injured, and there were more than a dozen dead bodies of city guards lying on the ground.

Their opponents were more than a dozen humanoid mechanical puppets, each two meters and one meter tall, with a red light on their heads. They attacked slowly but fiercely, and with one punch they smashed the ground, creating a one-meter-round hole with astonishing force.

At this time, Tang Xihe was relying on the physical fitness of a third-level psychic to deal with the iron lumps. She was holding a beast leather whip and attacking the joints of these mechanical puppets.

Without the blessing of the fire element, she would have to attack more than ten times in a row to break a joint, which was extremely inefficient.

Suddenly, a mechanical puppet raised its hand and shot a mechanical rope towards Tang Xihe at an extremely fast speed.

It seemed that the rope was about to tie up Tang Xihe.

A figure flashed by at a high speed, hugged Tang Xihe and avoided the mechanical ropes.

Tang Xihe was delighted when she saw Chen Wangping, but she also said anxiously, "Retreat quickly! These mechanical puppets are too powerful. We have suffered heavy losses."

Chen Wangping looked around and quickly asked, "Where does this gas come from? Didn't you say it was safe here?"

Tang Xihe pointed to the door behind the mechanical puppet and said, "We were exploring the left firewood room before, which was safe. Ten minutes ago, we came here to explore the right firewood room, but as we approached, the main door suddenly opened on its own, and a large amount of poisonous gas came out. Then, more than a dozen iron lumps rushed out. They are too powerful. Without the fire element, we can't resist them at all."

Chen Wangping looked in the direction and found that the main gate was releasing black gas continuously just as Tang Xihe said.

He glanced at the radar and found that the nearby mechanical puppets displayed on the radar were actually red squares. The squares of the eleven mechanical puppets around him were about the size of three-centimeter square carrots.

"Square? Round? Will there be a triangle in the future?"

Without giving it much thought, Chen Wangping ran to a safe place with Tang Xihe in his arms, put her down, and stuffed two mugwort stalks into her mouth. He lowered his head and said, "Wait here for a moment. I'll go close the main gate. This isn't a solution."

Tang Xihe also knew the key point, nodded, chewed the mugwort hard, and used a whip to help other city guards.

The mechanical puppets seemed to know that Chen Wangping was very powerful. When they saw him coming, they immediately separated four mechanical puppets to try to stop him.

But Chen Wangping had no desire to fight. Relying on the resistance of the mugwort fossils to these poisonous gases, he quickly moved towards the main gate.

After arriving at the main gate, he raised his hand and threw out a dozen steel plates, which he quickly pasted directly on the main gate with clay. In the blink of an eye, he had completed the blocking operation.

Mechanical puppet: “….”

After blocking the door, the poison gas had no way to be replenished, and even these mechanical puppets seemed to move a little slower.

Chen Wangping turned around and poured dozens of buckets of slaked lime emulsion toward the main gate, and the ground suddenly became white and turbid.

"Click, click, click."

Maybe it's because of disrepair, or maybe it's for other reasons.

The slaked lime emulsion that Chen Wangping originally wanted to use to neutralize hydrogen sulfide fell on the mechanical puppets, immediately corroding them and causing them to lose a layer of skin.

At the same time, the poisonous gas without a source was quickly neutralized by the slaked lime emulsion, and the air became much better.

Seeing that the mechanical puppet's movements had slowed down, Chen Wangping quickly seized the opportunity, stepped closer to the mechanical puppet, and while the mugwort fossil was dispersing the surrounding flammable gas, he struck it with a thunder palm.

"Sizzle, sizzle."

When this thunder palm struck the mechanical puppet, electric sparks suddenly appeared on its chest, and its joints began to swing around.

Tang Xihe saw the electric sparks from a distance and shouted anxiously: "Be careful, don't use fire!"

But the next second, she saw the mechanical puppet dancing wildly as if it had cramps, with red light flashing rapidly in its eyes, and after a few seconds it fell to the ground, unable to move.

"Iron bumps? I don't believe you don't need a chip."

Chen Wangping smiled slightly, raised his hand and chased after the other mechanical puppets, slapping them one by one. In just a few minutes, he knocked down seven or eight mechanical puppets.

The remaining mechanical puppets also seemed to know how to judge the situation. Seeing that the situation was not right, they gave up the city guards in front of them, turned around and lay on the ground, their fists and feet turned into wheels, and ran towards the woodshed that Tang Xihe had mentioned before.

"Want to run? You think this is your home, you can come and go as you please!"

Chen Wangping was envious of the intelligence of the mechanical puppet. He quickly caught up with a mechanical puppet that was in the escape state, raised his hands and slapped it twice, knocking it to the ground and making it unable to move.
