Early in the morning, just after sunrise, Xiao Ming had already urgently left the room, went straight to the security room, and took out a box of gunpowder explosion.

met Wang Li at the door of the dormitory, and the two looked at each other and smiled, both understanding the anxiety in each other's hearts.

"Let's go, let's go research and research!"

Xiao Ming pulled Wang Li up and went to the location where they had already started construction! A small pit was in front of him, Xiao Ming threw the box down directly, and the two of them carefully went down into the pit.

Wang Li brought the ice-breaking chisel, and the two of them made a few gestures, pointed to a position and chiseled a few small holes first, and then put the blaster into the small holes.

"I've got an introduction here!"

Xiao Ming took out a long primer from the box, tied several explosive primers together, and then took out a lighter and lit it. Seeing the spark of 'Zizi' quickly ignited, the two got up and ran, found a position that could cover and squatted down directly, lowering their heads and covering their ears.

'Boom! ’

Several explosions resounded in the sky, alarming everyone in the dormitory building, and the crowd poked their heads out to see the excitement. Director Xiao and Officer Gao walked out directly and went to the excavation place.

When they arrived, the big pit had already been blown out of a deep pit, Wang Li and Xiao Ming poked their heads out of one place, and when they saw that no one was injured, Officer Gao and Director Xiao were relieved.

"What's going on?"

But Officer Gao still frowned, looking at the two of them reproachfully, he actually acted on his own initiative, if there was any accident, see what they should do!

"Officer Gao, it's me who is wrong, I am anxious to see the effect, but I didn't expect the movement to be so big!"

"Xiao Ming, how old are you, and you still don't know how to measure!"

"I'm sorry, I was reckless!"

Xiao Ming was righteous and stopped all the responsibility on himself, Wang Li wanted to bear it together, but he pressed it. However, Officer Gao didn't really blame them, but after a little warning, the matter was over!

On the contrary, now, he is more interested in what kind of scene after the blasting!

A few people went over to check, and the big pit was blown up in pieces, and scattered ice cubes were piled up in the pit. Xiao Ming and Wang Li jumped down directly and pushed away these scattered broken ice, but they didn't expect that there would be an unexpected joy!

"It's cracked, Wang Li, look, it's all cracked here!"

Xiao Ming moved a large block of ice away, revealing the ice surface full of cracks below, Wang Li hurried over, and it was really cracked!

The cracks spread out along the small holes, and the ten holes extended dozens of cracks, large and small, like spider webs, spreading into the inside of the ice.

Wang Li stretched out his foot and kicked on the deepest crack, and kicked a whole piece of ice away with great ease, such a surprise made everyone at the scene couldn't help but get excited.

"Great, Xiao Ming, you and Wang Li organized good people to dig out all the ice cubes, and be sure to clean up the teaching building as soon as possible!"

Gao Warning gave the order, Xiao Ming and Wang Li immediately became active, and in the crowd of onlookers, they called their brothers, and called the crowd that had participated in the excavation operation before, and acted together.

It can be said that everyone went to get tools, jumped into the big pit, first cleaned out the broken ice, and then began to dig on the cracks.

The cracks are deep and shallow, and the deep places can be easily pried open with ice-breaking chisels or sharp tools, while the shallow cracks need to be beaten with a sledgehammer.

Almost everyone present participated, with men with more strength carrying large pieces of complete ice, and children or women with less strength helping to clean up the broken Xiaoice cubes in the ice pit.

With the help of everyone, in less than an hour, the progress is many times faster than before!

The closest building to the dormitory building is a dual-purpose building for teachers' offices and teaching experiments, so the floors are not high, only six floors.

The large crater they used gunpowder to blow up was three or four meters deep, and with the excavation of manpower, the top floor of the school building can now be seen.

Next, if you want to continue to use gunpowder blasting, you can't be as casual as before, and you have to calculate the direction, but you can't blow up the structure of the teaching building together.

Fortunately, among the masses, there were many students in school, including many science students, and after their measurements and calculations, the location of the next blast was finally determined.

There must have been three selected sites, and in order to control the blasting range, they reduced the amount used this time, and used five barrels of gunpowder for blasting at each location.

After digging a small hole in advance, putting the powder tube in, and then tying the five tubes of gunpowder together with an extension primer, when ready, the crowd of people watching the excitement was dispersed.

Everyone stayed in a safe range, and then Wang Li, Xiao Ming and Xiao Li respectively ignited the primer.

With the ensuing explosions, small black mushroom heads rose, and the scene was covered by black smoke, with a strong and pungent smell of gunpowder that made everyone feel uncomfortable!

When the smoke was blown away by the cold wind, everyone opened their eyes and looked ahead!

"It's done!"

Xiao Ming was the first to rush over, and the nearest location was smashed into a big pit, and the cracks in the road extended, and they were connected to the cracks that exploded on the ground in the other two places, forming a huge grid in the ice!

Some of the cracks have collapsed, and the exposed section can clearly see the building that is frozen in the ice.

"It's worthy of being a top student, it's amazing!"

For such a surprise, Xiao Ming and others had to admire the power of knowledge, and they loved this student even more.

Under the extraordinary performance of the top students, their excavation speed is like divine help, but it has only been about half a day, and the third or fourth floors have been dug out, and the remaining floors are already being excavated, and I believe that the teaching building can be dug out today.

In the open space next to it, there are large blocks of ice, and with continuous excavation, the ice cubes have occupied a huge place! Senior police officers deliberately set up a team to transport the ice farther away, so as not to cause obstructions or collapse and create new problems.

The blasting and excavation are in full swing here, and the hotel, Luo Yu, and they are finally able to use electricity normally because of solar energy storage.

Gu Yan and Zhang Fei connected part of the solar energy to the hotel's power system, and as long as they bask in the sun for one day, they can supply electricity to several rooms in the hotel.

The lights in the room and toilet can be lit, which is much more convenient than using outdoor lights for lighting. And now that there is electricity on the socket, they can still charge the appliances!

"It's a lot of movement in the Vault today!"

Even though the two places were separated by a distance, they could hear the explosion coming from the shelter, presumably the same people from yesterday who brought explosives such as gunpowder and blasted the ice open!

Zhang Fei was quite curious and wanted to go over to take a look, but Luo Yu and Su Mei were not interested, and they did not oppose or approve! In the previous life, it was also around the same time, and a group of people brought gunpowder to the shelter to support.

In a very short period of time, several teaching buildings were excavated, which successfully solved the problem of living in today's people.
