"Boom"!

There was a loud bang, and everyone's faces changed.

Smoke and dust rose and filled half the sky, making it impossible to see what was going on behind it.

Yan Ji and Zhu Gantang stood up from their chairs in unison and stared at the other side.

They still remembered Xu Wen's instructions, and they didn't rush forward, but young people like Ni Tianyang and Zhu Shishi couldn't hold it back at all, and they slipped into the smoke and dust.

Lin Xie took two steps forward and wanted to go in, but after hesitating, he still stood still.

He walked up to Xu Wen, stared at the side, and his voice trembled slightly: "This momentum...... It's amazing!"

They were already far away, but the shock wave was wide, and the winds still blew their clothes and hair.

Although Lin Xie was dressed dirty and torn when he met Xu Wen for the first time, he actually attached great importance to his image. But at this time, he couldn't even bother to tidy up his messy hair, which showed the shock in his heart.

Xu Wen didn't speak, he was also staring over there.

Although he has experimented with the same formula in modern times, after all, it is a different era and different environment, and what kind of situation it will be here is not very bottom-notch.

"You two come back!" he didn't bother to talk to Lin Xie and shouted in the direction where Ni Tianyang and Zhu Shi had disappeared.

"It's okay, it's okay...... Ahh

Xu Wen was in a hurry, and rushed into the smoke and dust with an arrow step, and hurriedly went to investigate the situation.

At this time, the smoke and dust also dispersed a little, and I could see the situation inside clearly.

They're experimenting with detonators/tubes today, targeting a raised rock.

They planted the detonators/tubes in advance, everyone took refuge in the distance, and then ignited the detonating wire.

After seeing it clearly, Xu Wen breathed a sigh of relief.

Ni Tianyang was fine, but just when he was approaching, another rock fell down, which startled him.

Xu Wen walked over, frowning and complaining: "You guys are too careless, I said before, you must pay attention to safety rules." If you disregard your safety like this, I'll have to get you out of here. ”

"Don't!" Ni Tianyang was startled, and immediately shouted, "I will be honest!"

Zhu Shishi was also frightened, and nodded again and again, indicating the same meaning as Ni Tianyang.

For them, this new explosive was so amazing that they didn't want to miss it. "It's huge. At this time, the smoke and dust had completely dissipated, and Yan Ji came over to inspect the situation of the mountain and rocks. After the examination, his expression was relaxed, but he frowned, and he could not tell whether he was happy or unhappy at all.

Or maybe at this time, his emotions are also very complicated.

"It's very precise. Zhu Gantang walked over with him and noticed another thing.

This rock is granite, so hard that it takes a lot of effort to blow it up.

But now it has been blown open, from top to bottom, a total of five huge cracks, very thoroughly, and even has a neat and refreshing feeling.

At the same time, the width of these five cracks is about the same, and the size of the six rocks blown out is also about the same, which is also the goal they planned at the beginning, and now it has been successfully achieved, and the effect is very good.

"It's really ...... that Brother Lian was able to research such a strange thing and hide it all the time" Yan Ji sighed, not knowing how to express it.

Xu Wen threw this pot to Lian Tianqing at the beginning, and now he doesn't explain.

He didn't need more credit for this, saying that even Tianqing's things could make them a little more jealous.

"In this case, it is indeed not a problem to open the mountain and quarry, but how to use it, we have to discuss it with Wu Liu again. Yan Ji said to Xu Wen.

"There are also various safety norms and codes, which must be carefully drawn up, and everyone must follow them, otherwise they will be dealt with strictly and will not be tolerated. Xu Wen said as he glared at Ni Tianyang and Zhu Shi.

Both of them shrank their heads at the same time, and their expressions were exactly the same.

"That's one thing, ......and on the other hand," Yan Ji pondered, "you don't have to let too many people learn this, just form a team and let certain people do certain things." ”

He raised his head and looked at Xu Wen, who nodded slowly, understanding what he meant.

Explosives with such great power and precise control can be used for more than just quarrying. If you let it leak out......

"This team has to be in charge of you, and the number of people who know the recipe has to be in the single digits. Any increase needs to be reported. Yan Ji said.

"Hmm. This is a very reasonable consideration, and Xu Wen has no objection.

The next group of people did not speak, and fell silent around the rock.

Ni Tianyang and Zhu Shi are more special, and these are not a matter for them, they are more concerned about the technical issues related to this matter.

How to control the detonator/tube detonation, what kind of effect to achieve, and what kind of application it can be used in, the two people discussed hotly.

Xu Wen glanced at the two of them, on the one hand, Mo Ming felt a lot more relaxed, and on the other hand, he was thinking that the two guys who needed to be controlled the most were these two guys, and if they were on top, it would not be strange what they would do.

"I'm here to see them. Lin Xie suddenly took the initiative to say.

"Hmm. Yan Ji glanced at him and agreed.

Very smart.

Obviously, Lin Xie also saw the importance of this yellow powder, and chose the most suitable time to join in.

This will inevitably add some leverage to some of his future competitions.

Lin Xie looked at Xu Wen and nodded quietly.

Of course he knew who had brought him an advantage, and although one of the purposes of his coming here was this, he didn't ask, none of that existed.

Xu Wen nodded back, and said nothing more.

Yellow powder is indeed a very important thing, it is bound to bring great changes to the world, and it is natural to change a person's future.

But for Xu Wen, it's just one part of the process.

Of course it's not insignificant, but it's not that important, he finishes this and goes on to other things.

Building this city is an excellent learning opportunity.

Countless masters gathered here, they wanted to see something new from Xu Wen, and they inevitably joined in, took out their housekeeping skills, and reflected with it.

Xu Wen studied hungrily, and the masters did not hide anything in front of him.

A trip to the Liuyu Society, as if some kind of tacit understanding was reached among them, at this time on the construction site of Xinfeng Spring City, the self-cherishing of the broom has become the most unnecessary and outdated concept.

Now, not only with Xu Wen, but also with Xu Wen, the relationship between them is also very harmonious, and the communication is almost unreserved.

They were originally the top masters of this era, there were not a few ink workers, and there were also those who touched the edge of heaven, when their ideas began to exchange, skills began to communicate, they also began to grow, and their progress was almost a rapid progress.

This is directly reflected in the new city under construction.

Landslides crack, terrain changes, and roads are opened.

Countless people and countless things poured in, and countless technologies converged into it.

This brand-new Spring City is perfectly moving in the direction that Xu Wen planned in advance-

No, it's better than that.

And Xu Wen is getting better and better day by day.
