"white!"
"Very good!" Yip hon back to find ping Ouyang pointed to the valve, "Ouyang ticking time bomb can be detonated remotely."
"Yes!" Ouyang Ping did it at once, and when he packed the explosives, he saw that Yip Han’s two fingers acted as wrenches and slowly screwed simple bolts.
Ouyang Ping’s eyes are straight. What the hell is this?
Half a minute passed, and Yip Han dismantled a section of pipe and put it aside. As soon as he arrived, he ordered the troops to cease fire. The guns suddenly stopped and the soldiers burned their asses and ran back.
At the same time, yip hon struggled to twist the valve, and Ouyang Ping immediately heard the hissing of air leakage, and the sound became louder and heavier.
Ouyang Ping gave a shudder. He finally realized what was in the valve-it was gas, a combustible gas!
Ye Han turned the valve several times like a steering wheel, and then started to run like an arrow rabbit. "Withdraw quickly!"
The soldiers also blew up the nest and flew behind yip hon.
The two evacuation teams met in the corridor and quickly withdrew from the original road. A large group of insects followed closely behind, and you couldn’t see that this army had just beaten the insects to the north.
Ye Han ran back to the Tibetan room in one breath and waved his hands. The soldiers struggled to push the large and small boxes to grab the insects and blocked the door of the library before they rushed over.
That’s not to mention that Yip Han ordered everyone to withdraw the maintenance passage and cover it up as a ceiling exit. Only then did he breathe a sigh of relief, "How long has it been?"
Ouyang Ping said, "Forty-seven seconds!"
"It’s a little short … wait a minute!"
Ouyang Ping asked curiously, "Captain, what is that valve released?"
Yip hon ha ha a smile "I don’t know? I just found out that there was a coal mine at the end of the West June 4th, and when I built the city, I specially drilled through the rock stratum to collect gas from the West June 4th fuel. "
Luo Qi could hardly close his mouth. "Is this ok?"
Ouyang Ping’s reaction is much more intense. "No, this thing can’t be blown up when the concentration is high. It must be detonated immediately!"
Speaking of this, he has understood Yip Han’s idea that the detonation effect is no different from that of fuel air explosive after the gas is released to a certain concentration by hitting the valve. Even if the insects in the North Third District are not killed by the explosion, they will suffocate because the explosion consumes a lot of oxygen.
"Then hurry up" Yip hon good advice.
Ouyang Ping immediately sent out the initiation signal, but after waiting for a few seconds, there was no sign of explosion, that is, no noise or vibration.
Yip hon expression solidified "what’s the matter?"
I don’t know! Ouyang Ping panicked and sent several signals in a row, but there was still no response.
Luo Qi said, "Is the concentration high?"
Ye Han shook his head. "Is the concentration high or not?"
Ouyang Ping said hesitantly, "Why don’t I go out and have a look?"
"No need," said Yip Han. "Is it too late?"
"Yes!" Ouyang Ping nodded. "It should be that the gas concentration exceeds the standard."
The limit of gas explosion is 53% and 15%.
Yip Han frowned. "What’s the result of exceeding the standard?"
Ouyang Ping said, "I haven’t seen how it burns when it meets fire."
Yip hon gritted his teeth. "The door sends another signal!"
Several soldiers immediately shouted, "We found that the concentration of combustible gas is 7%!"
Yip hon can’t wait to shout "Quick!"
Ouyang Ping hurriedly sent out a detonation signal, and there was a faint explosion in the hiding room.
The door soldiers are quick to put the cover on the exit. Before they put their hands on the face, a huge force suddenly lifted the cover, slamming the soldier’s body and then a flame poured into the maintenance passage near the exit. The soldier was either knocked over by the cover or blown down by the airflow.
The explosion came and went and rushed into the maintenance passage, and the flame quickly subsided. Yip hon shook his head and got up and shouted loudly. "What’s going on? Is there anything wrong? "
