You know, the tunnel operation is actually a very professional job, not simply digging the tunnel, digging the tunnel needs to take into account a series of extremely professional problems such as water permeability, water clearance, detoxification gas, collapse prevention, etc., even in the 21st century, some large mines will still have mining disasters, so Guo Dalu does not dare to carry out such a difficult way of operation, simply use the most barbaric and crude mining method - open-pit explosion mining!

This explosive, of course, is black powder. Pen, fun, and www.biquge.info

The villagers of Houlong Village have actually seen black powder powder for a long time, when Yu Dazhong left the palace to plot Houlong Village, in order to resist the enemy and protect the village, the stupid big man and others used black powder canisters, and for a time the robbers, mercenaries, and monsters were blown to ashes, but they didn't know that this black powder could also be used to open mines.

At that time, in order to demonstrate the power of black powder mining, Guo Dalu personally made a hole in the rock wall with his tail, stuffed it into the granular black powder, and lit the fuse - Li Dayan and others were curiously watching the fuse disappear into the rock crevice with sparks, and they heard a thunderbolt in their ears, and the indestructible mountain rock turned into a sky of rubble, falling from the sky like a goddess scattering flowers.

Li Dayan looked at the pile of rubble like a hill under the rock wall, and he was so shocked that he couldn't close his mouth - if he used manpower to beat it with a sledgehammer and steel drill, he wouldn't be able to smash such a pile of ore in ten days and half a month!

Since then, the cannon rumbling in Fengshen Mountain, with the help of black powder, truckloads of ore have been transported out, and Li Dayan and other miners have gradually discovered some characteristics of black powder explosion, such as using black powder to fill holes, which need to be sealed to be powerful in order to blow up more ore, and black powder cannot be compacted by moisture, granular black powder is more powerful than powder--even Li Dayan also followed Guo Dalu to learn the preparation of black powder, and he learned it well, and now he can operate completely independently.

However, as the scale of mining in the mine is getting larger and larger, the original unique single-eye explosion method is becoming more and more insufficient, Li Dayan whimsically invented the series of explosion methods, that is, to punch multiple holes along the direction of the ore veins on the mining surface, and then detonate at the same time, and a large number of ores can be exploded at once.

It's just that this method has extremely high requirements for the understanding of ore veins and the grasp of the direction of explosion, not to mention that in the absence of a timing detonator, it is only the use of different lengths of the fuse to detonate more than ten explosion points synchronously, how difficult it is!

However, Li Dayan has Chen Qingdai, this violent dragon girl is very interested in black powder, every time she detonates, she has to light the fuse with her own hands, and muttered in her mouth: "I have to let the invention surnamed Guo explode black powder in the water, hehe, detonate a few explosive packets in the Crystal Palace, I don't know how refreshing, just tie the explosive packs to a few key pillars, and then--boom, hahahaha--"

At this time, Chen Qingdai had already lit the last fuse, because this fuse had to catch up with other fuses that had been lit and detonate at the same time, so it was relatively short, and the sparks were sizzling on the fuse and quickly disappeared into the rock crevices.

At the foot of the mountain, Li Dayan jumped to his feet in a hurry: "Daiyu, Daiyu, my Aunt Chen, come down!"

Chen Qingdai threw the torch in his hand, jumped on the rock wall with a few taps, and had already jumped to the bottom of the mountain, pulling out his feet and running towards the hiding place of everyone at the foot of the mountain, at this moment, there was a bang--no, not a sound, but a series of dense explosions, which were combined into a single sound--a total of three hundred kilograms of black powder exploded!

Chen Qingdai jumped forward - several pairs of big hands stretched out, grabbed Chen Qingdai, and pulled her into the bend at the foot of the mountain - boom, countless gravel and sand particles rushed over in a large puff of smoke and dust, almost clinging to Chen Qingdai's feet, flying in all directions.

Li Dayan's face turned a little pale, and he complained to the triumphant Chen Qingdai: "My little aunt, you don't want to leave more fuses, you see, how dangerous this must be, it almost hurt you." If you are really injured, how can I explain it to Brother Guo. ”

Chen Qingdai patted the ash on his body: "No way, who told us to match the progress of black powder and fuse can't catch up with the construction? I'm better than others, so I'll try to save some black powder and fuses. ”

Li Dayan said bitterly: "Brother Guo has repeatedly reminded us that we would rather slow down the progress of mining, and everything must be based on safety as the first priority, he doesn't want bloody ore, no matter who he hurts, he will be heartbroken." ”

Chen Qingdai flattened her mouth: "That black guy, say so, but everyone knows that if we don't take advantage of the abundant labor force in winter to mine more ore and hoard, when spring begins, a large number of migrant workers will go home to cultivate the fields in the spring, and our workshops and blast furnaces will stop work if they don't do well." ”

-- Although Guo Dalu made a big effort to carry out a contract liability law in Yinxian County, after all, he did not dare to take too big a step, for fear of pulling eggs, and only dared to try it out in small quantities, so a large number of peasants were still trapped in the land and could not be liberated, let alone train a large number of high-quality industrial workers in a short period of time.

Li Dayan nodded again and again: "Miss Chen is really heartbroken for Brother Guo'er's great cause--"

Chen Qingdai's face suddenly turned pale: "Uncle Li, how many times have I told you, I don't do things for the kid surnamed Guo, I do it for myself, do you think that all the women in Houlong Village have to surround the surnamed Guo? Hmph, some people are careful and pretend in front of him, but I don't care about it!"

Li Dayan knows who Chen Qingdai is talking about pretending to be - naturally refers to Guo Lanying, who has been in the limelight the most recently, as the story of Liang Zhu spreads all over the south of the Yangtze River, the gossip that the former Xiangxiang girl Guo Lanying is favored by Mr. Houlong has also spread all over the land of Sanjiang. Although Guo Lanying returned to Houlong Village, she did not quarrel with the big girl, a genuine woman, as expected by the villagers, the two are still as close as ever, going in and out together, and there is no out-of-the-ordinary performance between Guo Dalu and Guo Lanying.

The villagers all said that the big family has the rule of carrying a concubine into the door before officially marrying, and first warm the bed for the master, it seems that this Guo Lanying is to warm the bed for Guo Dalu, maybe earlier than the big girl enters the door of Guo's house.

These words reached the ears of Li Dayan and others, they were originally men in the army, a group of rough people, but they didn't think there was anything wrong with a good prostitute with Mr. Houlong, in the army, there are many generals who marry the battalion soldiers home, as long as they are not the right lady.

It's just that Li Dayan doesn't like a small and gentle woman like Guo Lanying, and thinks that a good woman should be like Chen Qingdai, with more strength than a cow, jumping like a fly on the mountain wall, such a woman can help Guo Dalu make an earth-shattering career!

Li Dayan is a straight person, so in his usual words, he often holds grievances for Chen Qingdai, and feels that Guo Dalu should carry Chen Qingdai into the door in addition to marrying a big girl.

However, Chen Qingdai hates this matter the most, she actually agrees with Guo Dalu's theory of equality between men and women and women who can hold up half the sky, why should women obey men in everything, she even faintly thinks in her heart that men should not have three wives and four concubines, can women always be attached to men like vines?

Li Da saw Chen Qingdai's color, and said with a smile: "Okay, good, our Daiyu is not inferior to men, she is a good man who can run a horse on his arm!"

Chen Qingdai was about to say something, suddenly her feet were weak, one leg was bent down, Li Dayan hurriedly helped her, Chen Qingdai looked back, but saw a dark red mark on the trouser tube of her left leg, which was a blood stain!

Chen Qingdai lowered her voice and said, "Don't make a sound, so as not to scare people." It was just a blow from a flying stone. ”

Li Dayan hurriedly said: "Hurry up and bandage it! There is alcohol and notoginseng powder in the warehouse--"

Chen Qingdai grabbed Li Dayan's arm: "Uncle Li, don't panic! I feel the demonic aura on the nearby mountain! There is an enemy peeping at us!"

Li Dayan was an old man, and he didn't put his expression on his face, he stabilized his mind and said: "I know, I will quietly call the miners to the warehouse, and prepare the stainless steel armor and swords - Brother Guo has long expected that there are monsters in the mountains that may disturb trouble, and with a plan, ordinary little demons will make them come and go!"

Chen Qingdai nodded: "Untie Da Hei from the car, this guy eats all kinds of ores when he sees the sky, and it's time to move his muscles and bones!"

At this time, the miners had already rushed up, piled up all the large piles of ore that were blown down on the trolley, transported them to the side of the track, and then used a simple hoist crane to transport the ore onto the wagon. ”

Da Hei half-closed his eyes and flicked his tail: "Don't be busy, they are all unpopular little demons, as soon as I make a move, Grandpa Hei, I can step on them." ”

Don't look at Da Hei in Houlong Village honestly, pulling a cart to plough the fields, a picture of an old cattle, everyone has forgotten that it is also the former master of the party in Fengshen Mountain, although it does not eat blood, but it is not easy to provoke, the fierce beasts near its cave are extinct, and ordinary monsters also walk around.

At this time, a group of miners who were originally military men had quietly entered the warehouse, put on armor, some held swords, and some grabbed the black powder bag used to open the mountain. (To be continued.) )
