Before Chen Wangping could think carefully about what this was.

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

He smelled through his mask and found that there was a very faint smell of rotten eggs in the smell.

"The smell of rotten eggs? Is there volatile hydrogen sulfide?"

Chen Wangping vigilantly put away the lightning energy, took out the fossil of mugwort, placed it on his chest, and used the cold light to explore inside.

You can't use lightning energy anymore, and sparks will explode whenever you have a thousand.

When he thought of this, he immediately rushed towards Tang Xihe's position with a quicker thought.

Since there is hydrogen sulfide and he cannot use lightning energy, Tang Xihe must not use fire elements either.

Danger!

Sure enough, Chen Wangping rushed in front of the map for two minutes, arrived near the secret library, and when he turned around, he heard a tragic shout:

"Miss, we will cover you to leave. These iron lumps are so awesome."

"Miss, go quickly, you can use the fire element when you leave here!"

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

Looking at the sound, Tang Xi and more than 20 city guards around him were injured, and more than a dozen city guards were still lying on the ground.

Their opponents are more than a dozen humanoid mechanical puppets, each of whom is two meters tall, with a red light on his head. He made a slow but sharp move. He punched the ground and directly smashed a big pit that was one meter round, with amazing strength.

At this time, Tang Xihe was relying on the physical fitness of the third-level psychic psychopath to deal with the iron lump. She held an animal leather whip and was specifically holding the joints of these mechanical puppets to attack.

Without the blessing of the fire element, she had to attack more than ten times in a row before breaking a joint, and the efficiency was extremely low.

Suddenly, a mechanical puppet raised his hand and shot a mechanical rope at Tang Xihe, which was extremely fast.

Seeing that the rope was about to tie Tang Xihe.

A figure flashed by quickly, hugging Tang Xihe and avoiding the mechanical rope.

Tang Xihe was happy when she saw Chen Wangping, but she said anxiously: "Retreat quickly, these mechanical puppets are too strong, and we have suffered heavy losses."

Chen Wangping looked around and asked quickly: "Where did these gases come out? Didn't you say that it was safe here before?"

Tang Xihe pointed to the door of the room behind the mechanical puppet and said: "I was exploring the left woodshed before, which is very safe. Ten minutes ago, we came over to explore the right woodshed, but as soon as we approached, the main door suddenly opened itself, and a large amount of poisonous gas came out, and then more than ten iron lumps rushed out. They were too strong and could not resist it without the fire element."

Chen Wangping looked along and found that the main entrance was releasing black gas outwards as Tang Xihe said.

He glanced at the radar and found that the nearby mechanical puppets displayed on the radar turned out to be red squares, and the squares of the eleven mechanical puppets around were about the size of a diced carrot that was three centimeters square.

"Square? Circular? Will there be triangles in the future?"

Chen Wangping didn't think much about it, hugged Tang Xihe and ran to a safe place to put it down, stuffed two mugwort trees into her mouth, and lowered his head and reminded him: "You wait for me here, I'll close the main door. This is not a solution."

Tang Xihe also knew the key point, nodded, chewing mugwort with force, and using a whip to help other city guards.

The mechanical puppet seemed to know that Chen Wangping was strong. When he saw him coming, he immediately assigned four mechanical puppets to try to block him.

But Chen Wangping was not in a slight desire to fight. Relying on the resistance of the mugwort fossils to these poisonous gases, he quickly moved closer to the main entrance.

After arriving at the main entrance, he raised his hand and threw out more than a dozen steel plates, quickly matched the clay and directly pasted it on the main entrance. In the blink of an eye, the door blocking operation was completed.

Mechanical Puppet: "......"

After blocking the door, the poisonous gas had no way to replenish it, and the mechanical puppets seemed to move a little slower.

Chen Wangping turned around and poured out dozens of barrels of ripe lime emulsion towards the front door, and suddenly the ground was covered with turbidity.

"Kake, kakake."

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

The ripe lime emulsion that Chen Wangping originally wanted to neutralize hydrogen sulfide fell on the mechanical puppet, and immediately corroded them and a layer of skin fell off.

At the same time, the poisonous gas that had no roots was quickly neutralized by the ripe lime emulsion, and the air became much better.

Chen Wangping saw that the mechanical puppet had slowed down a bit, quickly seized the opportunity, stepped into the vicinity of the mechanical puppet, and took advantage of the opportunity when the mugwort fossils dispelled the combustible gases around it, and slapped it with a thunder palm.

"Sheep."

As the thunder palm slapped, an electric spark suddenly appeared on the chest of the mechanical puppet, and his joints were waving around.

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

But the next second, she saw the mechanical puppet dancing wildly like cramps, and the red light in her eyes flashed quickly. After a few seconds, she fell to the ground and couldn't move.

"Iron goosebumps? I don't believe you don't use chips."

Chen Wangping smiled slightly, raised his hand and chased the other mechanical puppets, slapped one, and knocked down seven or eight mechanical puppets in just a few minutes.

The remaining mechanical puppets seemed to know how to judge the situation. Seeing that the situation was wrong, they gave up the city guards in front of them, turned around and lay on the ground, and their fists and feet turned into wheels, running towards the woodshed that Tang Xihe had mentioned before.

"Want to run away? Do you think this is your home, come whenever you want, and leave whenever you want!"

Chen Wangping was jealous of the intelligence of this mechanical puppet, and quickly caught up with a mechanical puppet that had entered the escape state, raised his hand and two palms to hit it until it was in place.

Tang Xihe was stunned. She saw the lightning rushing in Chen Wangping's hand, but there was no sign of explosion around her.

She rushed to Chen Wangping in confusion and asked, "What is that you just sprayed? It can actually remove poison gas? The effect is so good."

Chen Wangping explained: "It is ripe lime, which is made of quicklime calcined from limestone and water. It is highly alkaline and can be used to neutralize the gases emitted by these black oils."

Tang Xihe nodded slowly. She vaguely understood, but she didn't understand it completely.

However, she also knew that it was not the time to discuss these things, so she pointed to another woodshed next to the main entrance and said, "There are two woodsheds next to the main entrance. We have already explored the woodshed on the left just now, and there is no gain. When I rectify the team, should I go to the woodshed on the right to take a look?"

Chen Wangping took out the mugwort and handed it over and said, "Yes, you can clean up the team first. If you eat this thing one by one, you can expel the poisonous gas just now."

Tang Xihe took the mugwort and quickly ran over to rectify the team.

Chen Wangping glanced at the direction of the front door and first used a directional detection.

His mental power jumped back, and the information he brought back surprised him a little.

There were hundreds of dense red squares coming out from behind the main entrance, the smallest of which was three centimeters square, and the largest one was nine centimeters square!

Fortunately, these blocks are all bleak at this time and should not be activated yet.

Chen Wangping was very curious, "What is this? The secret warehouse of the Military Control Commission? Could it be that these are all combat reserve materials?"

Retracting his thoughts, he squatted down and carefully looked at the mechanical puppet, and found that the interior and limbs of the mechanical puppet seemed to have a light green system light.

Chen Wangping first removed the arms of the two mechanical puppets and found that both arms were very heavy. I guess the metal used when building them was very good. From the perspective of metallic luster, it should be the alloy used, and the color and weight are not the type of single metal.

He closed his arms expectantly and picked up a piece of them to check the attributes:

【D Alloy】

【Special effect - impact resistance: D alloy has excellent impact resistance, and can improve the acquisition efficiency by 20% after adding to the acquisition device]

【Special effect - corrosion resistance: D alloy has excellent corrosion resistance and can be used to create special armor】

【Note: D-merging metal is in the third-level alloy, with excellent cost performance】

After reading the attributes, Chen Wangping nodded with satisfaction.

This alloy is good, it can resist both impact and corrosion.

Excellent cost-effectiveness?

That's the question.

Where can I get the recipe for this thing?
Chapter completed!
