The militia company helped transport the materials, but did not go back. They moved into Xilongzhuang with tents, explosives and other tools.

Although these militiamen were professional veterans in the army and were asked to shoot and fire, they were stunned by fiddling with explosives, especially as Zhang Lang said, directed blasting, and had never learned this knowledge in the army.

Those who can blast directionally in the army are all professional talents and technical troops, and they will not be easily discharged from the army.

Fortunately, Zhang Lang is a reconnaissance company. Although he is not as good as a professional blasting soldier, he can do it even if he does.

Zhang Lang rushed to the militia camp and led several militia platoon leaders to draw lines along the mountain road to determine the gun hole.

"From here to the mountain bag over there, draw a line, and the inside is three meters deep, and gradually dive outwards, and according to the terrain, it will be unified to a horizontal plane." Zhang Lang pointed to the hillside and explained to several platoon leaders.

"That's all?" asked the militia platoon leader in confusion.

"This is only the first blast. Only after this blast is completed can the second precise directional blast be carried out." Zhang Lang explained patiently.

"There are also gun holes that need to be arranged in plum blossoms." Zhang Lang explained again.

"What is the arrangement of interlaced plum blossoms?" The militia platoon leader was born in a field army, so he knows this.

"Forget it, you can arrange for someone to bring lime. I will mark all the points that need to be drilled with lime for you." Zhang Lang patted his head and said helplessly.

Zhang Lang led the militia platoon leader along the mountain road, and according to the shape of the mountain, he spread the innermost roadside line on the hillside.

Then, sprinkle lime with lime to the drilling position.

The militia company does not have hole punching equipment, so it can only be punched manually.

All the laborers in the Dong family in Xilongzhuang were dispatched to use drills to dig out caves on the stones.

"Uncle Wolf, this is a hole that is three meters deep on the stone. If you don't say it can't be hit, it takes too time. Two people have to hit one hole for two days." Dong Shanzhu found Zhang Lang and expressed his opinion.

"That's right!" Zhang Lang slapped his head.

At this time, Zhang Lang realized that he had taken it for granted. There was no hole punching equipment. It took a day to make a three-meter-deep hole on the stone with manpower. A fifteen-kilometer mountain road also required seven or eight thousand holes per hole in a fifteen-kilometer mountain road.

More than 300 people punch 150 holes a day. When will this be done?

"How long does it take to punch a hole of 60 or 70 cm?" asked if you didn't understand. Zhang Lang never pretended to understand. He didn't realize it was embarrassing to ask others.

"Sixty or seventy centimeters, our village can drill three such holes in one hour." Dong Shanzhu thought for a while and replied.

After hearing this, Zhang Lang breathed a sigh of relief. He punched three holes of sixty or seventy centimeters in one hour, which was equivalent to punching a hole of three meters deep in two hours.

"Okay, let's start with the holes from the inside, and at the fastest speed, one hole is fifty centimeters deep, and we will explode in layers."

Zhang Lang quickly changed the mountain opening plan, drilled shallow holes, and carried out layered blasting.

After solving the problem of hole punching, the militia company and the people from the Dong family arranged to do hole punching operations first, and Zhang Lang rushed back to the greenhouse base.

There are still a group of people working there. Zhang Lang couldn't go over and take a look, and he was always uneasy.

The vegetable greenhouse is the cornerstone of his career. If something goes wrong with the greenhouse, it will not only waste time but also affect his prestige in the village.

Prestige is not easy to build, but it is much easier to destroy it.

Building roads, building greenhouses, and building pig farms are the three fires that Zhang Lang returned to the village. No matter which one cannot be burned, it will affect his prestige.

This is not only his prestige in the village, but also his trust in front of his leaders.

In order to burn these three fires, Secretary Xu, Minister Wang, and Director Tong supported him a lot.

For future plans, he must ensure that all three fires can be burned and burned vigorously.

When he arrived at the greenhouse base, more than a dozen pillars had been loaded in the greenhouse. Zhang Lang walked over and shook it hard, and the load was shallow and shaking a little.

Zhang Lang immediately called Zhang Jianjun over, "Jianjun is not good, change to longer wood and carry it deeper. It must be ensured that the pillars do not shake at all."

"I know Uncle Wolf, what should I do if these pillars are?" Zhang Jianjun agreed.

"Pull it and reload it!" Zhang Lang said simply.

"But it has been cut off..." Zhang Jianjun muttered.

"Stupid! You won't let these be put in front?" Zhang Lang cursed angrily.

"Oh! I understand." Zhang Jianjun touched his head and ran to make arrangements.

"Come back, I'll tell you, I'll check it back. This is my checking method." Zhang Lang raised his leg and kicked the post down.

"As long as there is a shaking tree, I won't beat your butt to eight pawns!" Zhang Lang threatened.

"Uncle Wolf, don't worry, I promise that there is no one shaking!" Zhang Jianjun shivered in fear and hurriedly promised.

The shadow left in his heart when he was a child was too great. Since Zhang Lang practiced martial arts with his master, he was older than average children. Children three or four years older than him could not beat him. In addition, he had a higher seniority and was the king of children until he left the army.

Zhang Lang was timid since he was a child. He often drilled into the mountains alone. He never stings with all kinds of delicious wild fruits when he listened to him and would allocate them.

The one who is disobedient is really beaten. The key is that Zhang Lang can’t find the injury after he beats him, but it hurts so much that he can’t even sue his parents.

After explaining Zhang Jianjun, he came to the place where Zhang Chenggong processed the wooden frame.

After looking at it for a while, Zhang Lang called Zhang Chenggong over and scolded him again, "What are you doing with the fine wood below? You can't crush it like this, but the sunlight also keeps you from outside."

"Uncle Wolf, am I afraid of not bearing enough weight?" Zhang Chenggong defended aggrievedly.

"How did Dog Heizi die?" Zhang Lang knocked Zhang Chenggong's head hard, "You're so stupid that you're done, what kind of wood is this?"

"Birch wood, such wooden strips can make a person's weight a three-centimeter weight. What are you worried about with a ten-centimeter wood square?"

"And this is eight millimeters thick glass, not as fragile as you think, just one meter of spacing!"

The hardness of birch is twice that of red pine, and iron birch is even higher than that of steel. This is specially made by Zhang Lang to replace the steel bracket.

Later generations built greenhouses in Northeast China used steel brackets and tempered glass, and Zhang Lang could not buy these things even if he had money.

I can only choose the hardest wood he can buy, birch.

"Oh! I understand." Zhang Chenggong scratched his head and arranged for someone to reprocess the wooden frame.

In fact, it’s not Zhang Jianjun or Zhang Chengben, but the greenhouse has never been seen before. Everything is like crossing the river by feeling the stones, and it is inevitable that there will be problems of one kind or another.

"Don't worry, wolf cub, everything has a skilled process." The fourth uncle came over to comfort him when he saw Zhang Lang getting angry.
