After several days of rain, it finally stopped on the night of the sixth day, and in the morning the clouds cleared, revealing a blue sky, and the sun was once again shining in the forest after a few days.

As soon as the rain stopped, Zhao Chen returned to the work state of the previous few days, taking people up the mountain to measure during the day, returning to the wooden house to draw at night, and occasionally fighting with Lao Qin in his spare time.

In just a few days, Lao Qin's chess skills have improved by leaps and bounds, this old guy is there every day with his left hand and right hand, it's strange if he doesn't grow, Zhao Chen knocked on the side and asked, and after learning that Lao Qin played chess with one step and ten moves, he refused to play chess with Lao Qin.

Just kidding, this is what I taught Lao Qin, if the piece of armor killed by Lao Qin is not left in the future, then it will be shameless?

"Boy, come and fight with the old man!"

"I'm not free! There's a whole lot of work to be done! ”

"Sleeping on the couch and doing things?"

"That's... The kid is thinking about something! ”

“… The old man promised not to cheat this time! ”

People who are addicted to chess are probably what Lao Qin is like now, in order to be able to meet his opponent's next game of chess, Lao Qin even has to admit that he is cheating.

The search for the gold veins is still going on in an orderly manner, and the amount of gold that is washed out every day is increasing.

When one day, a pinch of gold the size of a bean grain appeared from the planed bamboo pipe, and Zhao Chen announced that he had found the golden vein belt, and the crowd suddenly erupted in earth-shattering cheers.

During this time, in fact, everyone is holding their breath in their hearts, this kind of daily approach to the goal, as if climbing the mountain, little by little, finally successfully climbing the peak, the sense of accomplishment in the heart, indescribable.

A large group of people shouted and shouted on the mountain, waving the tools in their hands excitedly, Zhao Chen was constantly thrown high by the excited crowd, and the whole person was drowned in the cheering crowd.

Lao Zhuang crawled on the ground, holding the few grains of gold, and his mouth was whining, not knowing what he was talking about, but he only saw the old guy's face full of tears, mixed with mud, and completely became a mud monkey.

The golden vein belt was found, and the gold reserves were very large, Lao Qin returned to the wooden house, excitedly reported to Li Er in detail about the golden vein belt, sealed it with fire paint, and handed it to Liu Cheng, a hundred horses, together with Liu Cheng's secret letter, which was carefully hidden by Liu Cheng, and hurried to Chang'an to report to His Majesty Li Er.

Lao Qin ordered a temporary rest for a day, and the Huotou Army made an exception to make a meal of braised pork for the whole army, and used up the prey that was caught a few days ago at one time.

This bastard has finally opened his mind since the last time he saw the spiced sauce beef made by Zhao Chen, and he begged Zhao Chen to teach him a lot of cooking skills, although the cooking skills are still so-so, but compared to the pig food he made, there is an obvious difference between heaven and earth.

"Boy, when the old man was in the daytime, I saw that something was wrong with you, what happened?" After dinner, Lao Qin walked into Zhao Chen's wooden house with a thermos cup, and saw Zhao Chen lying on the table, silently staring at a drawing on the table, and immediately frowned and asked.

When Zhao Chen heard this, he raised his head and looked at Lao Qin, smiled bitterly, and pointed to the drawings on the table, meaning to let Lao Qin see for himself.

"Boy, you know that the old man can't read these pictures!" As soon as Lao Qin saw Zhao Chen's expression at the moment, he knew that something was wrong, although he said that he couldn't understand it, he couldn't help but step forward and set his eyes on the drawings.

"The place marked by these dotted lines is what the kid said about the golden vein belt, which is very big, but you always look here..."Zhao Chen knew that Lao Qin couldn't understand it, so he pointed to the place marked on the drawings and said to Lao Qin: "Extending along the golden vein belt, it is a large rock group!" ”

As Zhao Chen spoke, he couldn't help but sigh and said: "This is what the kid has been worried about these days, once the golden vein belt extends under this rock group, then there will undoubtedly be an extra portal in front, and things will become extremely troublesome!" ”

"There's no other way around it?" Lao Qin stared at the drawings with wide eyes, and his expression suddenly became extremely solemn, if it was really according to what Zhao Chen said, then it would be equivalent to this gold mine that had just been discovered, and he would give up gloomily.

"There's no way around it!" Zhao Chen sighed and said.

If it is placed in the future life, this will naturally be no problem, even if it is a few hundred meters deeper, there is no problem.

But this is the Tang Dynasty, the mining industry is in the most primitive state, the depth is large, there is no way to solve the problems of drainage, exhaust and lighting, etc., if you insist on going your own way, it is to fill in with human life.

Lao Qin's face was gloomy, and he looked at the drawings without saying a word, and the fists on the table made a 'rattle' sound, and the joints of his ten fingers were already white.

During the day, the whole battalion was still reveling in the search for the Golden Vein Belt, but at night, reality gave him a big stick, and he was dizzy and at a loss!

Seeing Lao Qin's appearance, Zhao Chen paused, and then said: "I don't know the thickness of this rock group yet, if the rock group only crosses the golden vein belt, then things will take a turn, and we only need to chisel through the rocks then!" ”

"It's easy to say, how to chisel through!" Lao Qin raised his head angrily, looked at Zhao Chen with red eyes, and opened his mouth coldly.

With the current tools, when you chisel through such a large group of rocks, then wait until the Year of the Monkey!

"Ugh! As long as you can determine the thickness of the rocks, the boy will have a way to forge a tool to cut through the rocks! Lao Qin's angry appearance looked very scary, Zhao Chen looked at Lao Qin cautiously, and said tentatively.

"Harder than the tools here?" When Lao Qin heard this, his expression was slightly stunned, and then he frowned and looked at Zhao Chen, and asked in a somewhat solemn tone.

"It's probably the gap between heaven and earth!" Zhao Chen thought about it, secretly made a comparison, and finally replied in the end. As he spoke, he also took out a short blade from his backpack and handed it to Lao Qin.

Lao Qin is a veteran of a hundred battles, he has touched the blade for half his life, and as soon as the short blade is in his hands, Lao Qin's heart is shocked. Looking at the thin surface of the knife dotted with layers of snowflake patterns, Lao Qin tried to flick it with his hand, and there was a 'buzzing' tremor on the knife body immediately, only a weapon with good steel quality could emit such an intoxicating trembling.

As a result, Lao Qin's whole person suddenly seemed to have been hit by a sheep's madness, his whole body trembled violently, his eyes almost looked at Zhao Chen with fire, and his voice trembled and he spoke: "With such a ghostly forging technique, why do you hide it and refuse to hand it over?" ”

The more Lao Qin thought about it, the more angry he became, the short blade in his hand was light and extremely sharp, once such a divine weapon was equipped in the army in large quantities, such an army, Lao Qin trembled when he thought about it.

But this kid is actually hiding, if it weren't for the rocks, which need to be chiseled through by hard steel, I'm afraid this kid won't be ready to take it out for a while, thinking of this, Lao Qin became more and more angry.

"That, the kid didn't plan to hide it!" As early as the first time Lao Qin was angry, Zhao Chen wisely hid far away, looked at the angry Lao Qin cautiously, and defended: "Isn't this Your Majesty saying that you are in a hurry to mine!" ”

"Fart!" Lao Qin angrily pointed at Zhao Chen, who was hiding in the corner of the wall like a quail, and said angrily: "With such a ghostly forging technique, what can ten gold mines do?" ”

Zhao Chen stared at Lao Qin with wide eyes, and repeatedly confirmed that Lao Qin's fart was not after scolding Li Er, then he sighed and said, "Okay then!" It's not too late, boy, I'm going to draw it for you! ”

As he spoke, Zhao Chen left the corner of the wall and came to the table, just about to start drawing, the furnace for steelmaking and the corresponding data, but he didn't think about it, and as soon as he lifted the pen, he was slapped heavily by Lao Qin on the head.

"Boy's heart can be punished!" Lao Qin slapped Zhao Chen, and his angry face was bruised and roared: "What is the old man going to do with this kind of forging technique?" You should draw it for Your Majesty! ”

Gotcha, I forgot about this stubble!

As soon as Lao Qin saw Zhao Chen start drawing, he left Zhao Chen's wooden house as if his butt was on fire, and after a while, outside Zhao Chen's wooden house, there were three floors inside and three floors outside, and there were fierce soldiers standing with swords out of sheaths and bows and crossbows wound.

One by one, it is like killing a god, anyone who approaches Zhao Chen's wooden house for no reason, no matter who it is, it doesn't matter if he kills!

It's just a local method of steelmaking, why bother to make such a big battle! Zhao Chen looked at the soldiers outside who suddenly protected him like a national treasure, shook his head helplessly, and couldn't help muttering in a low voice.

But think about it, in this era of cold weapons, having the advanced steelmaking technique is equivalent to having the atomic energy of the later generations, and my heart will be relieved.

The real specification of steel is not smelted by moving the mouth, which involves all aspects of things, in this industry in the most primitive Tang Dynasty, to smelt such qualified steel, it is a fool's dream.

Fortunately, Zhao Chen smelted not that kind of steel, and local steelmaking was criticized for a long time in later generations, because under the special background of the times, the whole people made steel, and there were too many defective products.

But in fact, the local method of steelmaking is not impossible to produce good steel, as long as the proportion of carbon and alkali in the steel is mastered, it is not so uncommon for the soil method to make good steel!

The furnace of soil steelmaking was drawn in detail, and the places that need to be paid attention to in soil steelmaking were described in detail in a small book, as well as the specific operation, and when everything was completed, it was already the middle of the night.

got up and stretched, and saw through the window that Lao Qin was still lying on the recliner outside, Zhao Chen had no choice but to give up his intention to sleep, scratch his chin, and leisurely come to Lao Qin's side.

"Finished?" Lao Qin was lying on the recliner with a blanket on his lower body, and when he saw Zhao Chen coming, he looked at Zhao Chen and asked.

"Or else?" Zhao Chen reached out and picked up a piece of beef on the plate in front of Lao Qin, put it in his mouth and chewed it, and said angrily.

When Lao Qin heard this, he habitually raised his hand and wanted to slap Zhao Chen, but after lifting it, he didn't know what he thought, and the ghost made a fool of himself and handed the thermos cup to Zhao Chen.

Zhao Chen looked at Lao Qin in a daze, and suddenly felt a little uncomfortable with Lao Qin's sudden change.

Changed your sex?

Touched by my selfless dedication?

This is not scientific!

"Stinky boy, what do you think! The old man just wants you to take a sip! Lao Qin was a little embarrassed by Zhao Chen's strange eyes, and immediately withdrew the cup in annoyance and angrily, and roared at Zhao Chen.

That's right! This is in line with the image of an old thief!

"Uncle Qin, the kid has something to ask you!"

Seeing that Lao Qin had returned to his previous unreasonable appearance, Zhao Chen's hanging heart finally let go, so he sat down opposite Lao Qin, picking up the beef on the plate and throwing it into his mouth, while opening his mouth casually.
