He Zizhen waded through the water and walked over quickly, shining his flashlight towards Li Zhensheng's position. When he saw the black device on the pile of rocks, he suddenly became happy and said urgently, "This is an advanced individual soldier commonly used by foreign troops. As long as the excavation device is used properly, the efficiency is three to four times higher than that of the engineer shovel!"
He had already expected that the people who broke the shadow must be equipped with special digging devices.
Sure enough!
After seeing these advanced excavation devices, He Zizhen felt truly relieved.
At this time, he was finally 100% sure that the document was buried in this pile of ruins!
"Is this an excavation device?!"
Li Zhensheng and others couldn't help but be startled, with faces full of surprise.
"I'll teach you how to use it!"
While He Zizhen was speaking, he had already walked up to him, grabbed the device on the ground, and gently broke it off. Then he inserted his right hand into the middle of the hollow steel bar, and directly stuck his arm firmly inside.
Then he grabbed a clip-like handle in the middle of the device and squeezed hard, and the iron claws at the top of the device immediately tightened!
"Ouch, this is a transmission!"
Li Zhensheng perked up.
"Yes, this equipment is labor-saving and safe!"
He Zizhen said that as soon as he loosened his hand, the claws on the front of the device immediately released.
Then He Zizhen lifted the handle in his hand and dug hard into the mound.
Because the iron claws at the front end of the device have been specially treated, the resistance is very small and smooth when it is penetrated into the soil pile, and the combing and excavation speed is very fast. It can filter one cubic meter of soil in ten seconds.
“It also doubles as a shovel for digging!”
He Zizhen said and twisted the handle in his hand hard, and saw that the iron claws under the top of the device instantly turned, became parallel to the iron claws at the upper end, and fit perfectly into the gap between the upper iron claws.
In this way, the gap in the iron claw at the front end of the device is filled up, forming a shovel shape, which can be used as a shovel to directly throw soil and dig holes, which is very labor-saving!
"Hey, this thing is really useful!"
Li Zhensheng was immediately excited after watching He Zizhen's demonstration, "Thank you for coming in with us, otherwise we really wouldn't know how to use it!"
As he said that, he immediately took a device and put it on his hand.
Yun Zhou and Sun Jinzhong each picked up a device and put it on their arms. They followed He Zizhen's example and grabbed the handle and dug up the soil on the ground.
"There are three or four other devices like this here, so why can't we also install one on our left hand?!"
Sun Jinzhong had a sudden idea and touched an excavation device again and put it on his left arm.
Because the connection point of this device is very flexible and can be twisted at will, there is no problem in putting it on the left arm.
"Haha, now there are two equipments on the left and one on the right. Once dug, the efficiency will be doubled immediately!"
Sun Jinzhong was so excited that he immediately started digging around the mound.
"You're so smart, kid!"
Li Zhensheng smiled and immediately picked up an excavating device and put it on his left arm. Not to be outdone, Yun Zhou also grabbed an excavating device and put it on his left arm.
In this way, the three of them have six "iron arms", which greatly increases the efficiency of digging.
Although it is not doubled, the mining efficiency is definitely comparable to that of five people!
He Zizhen smiled when he saw this. Due to the injuries on his body, he could only wear an "iron arm", and he did not dare to use too much force. He chose an angle at the pile of rocks and began to try to dig in.
He had just observed the original excavation traces of the mound. The "Poying" group did not specify a fixed excavation direction, and they all excavated from multiple angles.
Because no one knows where the document will flow with the falling sand and gravel after the building collapses.
The only thing they can do is to dig in from different angles and pray that they can find the safe containing the documents as soon as possible!
On the other side, Kui Mulang, Zhang Xuwei and Jiang Lei, who were guarding the entrance of the tunnel, hid behind the bunker and looked attentively outside the entrance of the tunnel.
In order to better utilize the power of the light machine guns in their hands, Zhang Xuwei and Jiang Lei specially moved some rubble and concrete to build two simple machine gun stands, where the machine guns were mounted, with the muzzles of the guns facing the upper edge of the stairs at the tunnel entrance.
As time passed, it was noon again before they knew it, and all three of them were sweating profusely.
Jiang Lei even got a little impatient while waiting and murmured, "Why hasn't anyone rushed in yet?"
He couldn't hold back anymore and was eager to try out the power of the light machine gun in his hand as soon as possible!
