Tong Guan also had to stay in Lei Ze to monitor the Liangshan bandits, lest they sway and suddenly attack.

And without an edict, he Tong Guan can't leave his post casually, especially after the defeat now, when he is disliked by the emperor, Tong Guan doesn't dare to act rashly, so as not to give people a handle.

However, the matter of assisting the Liangshan thief Kou to negotiate peace is very important, and ordinary people Tong Guan trust it at all, and he is not at ease, so he can only do it with his own henchmen.

After thinking about it repeatedly, Tong Guan sent Bi Sheng back to Beijing, and at the same time wrote a handwritten letter and asked Bi Sheng to hand it over to Song Jiang.

Since the last time he touched a nail in Liangshan, Song Jiang has also lost a bit of favor in front of Emperor Daojun.

What's more, since the spread of football play, those professional players who were born in Keju quickly mastered the way to play football, and they played better than Song Jiang.

This made Song Jiang's importance in front of Daojun Emperor Zhao Ji drop a few points.

Tong Guan believed that as long as Song Jiang knew that Liang Shan's gang wanted to recruit An, he would definitely find a way to facilitate this matter in order to redeem his impression on the emperor.

Wu Yong, accompanied by Bi Sheng, entered Beijing together.

Shi Jin led an army of 50,000 to deter Tong Guan, and after receiving Wu Yong's message, he asked the army to stop advancing.

The performance of those recruits made Shi Jin very satisfied, and he was relieved to hand over the army to Lin Chong's command, and continued to put pressure on Tong Guan and the imperial court.

Shi Jin took Li Kui, Lu Fang, Guo Sheng and others back to Liangshan after a long absence.

Since going down the mountain, Shi Jindu has not returned to Liangshan for nearly a year.

Hearing that Shi Jin was coming, Ruan Xiaoer personally set up a small boat to pick up the marshal to cross the water.

Sitting on the boat, looking at the familiar Liangshan Shuibo, Shi Jin was in a trance, he had lived here for nearly four years, and he went up the mountain to assassinate Wang Lun and became the owner of Liangshan Cottage as if it was yesterday.

sighed, Shi Jin quickly came back to his senses, crossed the golden beach, and walked towards the cottage.

Now most of Liangshan's army is no longer on the mountain, but Liangshan's characteristics are easy to defend and difficult to attack, making it difficult for Shi Jin to completely discard it.

The original cottage has now become the largest weapons workshop factory in the Liangshan Army, with four furnaces and more than 300 blacksmiths.

Each iron-making furnace is 6 meters high, the diameter of the furnace base is 3 meters, the outer form of a cone, the bottom of the furnace is smaller than the belly, from the belly to the top of the furnace gradually shrinking, the furnace body is made of large red sandstone, and the inner side is coated with refractory mud.

These four iron-making furnaces can be said to be the highest level of iron-making in the Northern Song Dynasty.

The golden leopard Tang Long has returned from the south, with tungsten gold. Shi Jin came back to Liangshan this time to investigate metallurgical technology.

As soon as he walked into the cottage, Shi Jin saw Tang Long, the money leopard.

However, he looked as if he hadn't bathed in a month, wearing ripped clothes, a hairstyle like a bird's nest, and a pair of goldfish-bubble eyes, staring at the towering stove.

Shi Jin was very surprised when he saw Tang Long's current appearance. He said, "Brother Tang! ”

When Tang Long heard someone disturbing him, he didn't raise his head, and scolded directly: "Don't bother me!" Get lost! ”

Seeing that Tang Long dared to be so unreasonable to the marshal, Lu Fang was immediately furious.

He just wanted to step forward to teach Tang Long, the money leopard, a lesson, when Shi Jin stretched out his hand to stop him.

Shi Jin shook his head and motioned to Lu Fang not to disturb Tang Long.

Shi Jin could see that Tang Long was obsessed with his own world, and he didn't mean to offend himself.

For this kind of person, especially for technical talents who are seriously studying their own explanations, Shi Jin is always very tolerant.

Shi Jin didn't care about the furnace that was bubbling out with a boiling heat wave, and walked up the stone steps to observe the situation in the furnace.

In the furnace, the iron ore has melted, and the molten iron is flowing downward. But another ore, which should be tungsten gold as Tang Long said, has not yet melted.

Tang Long was very anxious when he saw it, and shouted loudly. "Speed up the blower, increase the heat!"

Hearing the order, several big men on the side of the stove immediately shouted slogans and pushed the lever back and forth vigorously, blowing the wind into the stove.

As the wind increased, the temperature in the furnace increased, and several sparks splashed out along the wind.

Shi Jin hurriedly retreated when he saw it, but Tang Long let Mars burn on him, his eyes just staring at the stove, observing the situation.

The little spark fell on him and quickly went out, but it burned out his clothes and left a little scar on his body.

No wonder he is nicknamed the Golden Leopard, and he is burned by these Mars.

Mars burned on his body, and Tang Long didn't care at all. I saw that the tungsten gold that was thrown into it finally melted and melted into the molten iron as the temperature of the furnace rose.

Tang Long finally smiled.

My grandfather's long-term wish for the stars finally had a chance to come true, and he was finally able to practice tungsten steel, forge a peerless weapon, and become famous!

As the molten iron flowed out of a stone trough, Tang Long hurriedly shouted, "Quickly pour the molten iron into the cement formwork!" ”

To cast the breech, there is no way to knock it out alone, you can only pour it into the template, wait until it cools, and then slowly beat it and polish it into shape.

When the molten iron was completely poured into the mold, the blacksmiths hurriedly sealed it, and then the eight big men worked together to carry the cement mold to another dry stone room with a lot of lime, and let it cool naturally.

At this time, you can't let it put it in the water and cool it down quickly.

Otherwise, once the gun chamber bursts or is seriously deformed due to the imbalance of cold and heat, then the gun chamber will not be usable.

Under the current conditions, it can only be cooled naturally.

It wasn't until he saw that the cement mold was safely put into the stone chamber that Tang Long was completely relieved.

He wiped a handful of sweat from his face, took out a bamboo tube hanging from his waist, and just wanted to raise his head to drink saliva, only to find that he didn't know when, Marshal Shi Jin was standing beside him.

Tang Long hurriedly put down the bamboo tube and said, "Damn it, I didn't know that the marshal was coming!" ”

Shi Jin said with a smile: "Brother Tang is polite, I came here without prior notice." I've been an uninvited guest! Please don't be surprised! ”

Tang Long said with some embarrassment: "Did the marshal come to see those tungsten steels?" This is not a small slack, but this tungsten steel is just a short time of refining, and please give the marshal a little more time, the small one can explore the best comparison of tungsten gold and pig iron, and make the best tungsten steel! ”

Shi Jin hurriedly reassured: "Brother Tang, I can't eat hot tofu in a hurry." I understand that! Don't worry, I'm not here today to urge you to make tungsten steel as soon as possible. That's right, recently we have been able to obtain more than 100,000 catties of copper, and I want you to tell you that all this copper is forged into artillery. ”

Tang Long was very afraid that Marshal Shi Jin was a layman, and felt that after refining tungsten steel, he could directly take it out and use it.

You know, even tungsten steel, it will be very different. Not every type of tungsten steel is suitable for the manufacture of a breech.

Now he heard that Shi Jin had not come to force himself to use tungsten steel to cast the cannon chamber, but to continue to use bronze. Tang Long breathed a sigh of relief and said, "This is no problem, I know the casting of bronze by heart." When the bronze comes, I'll call my men to cast it. ”

Shi Jin nodded and said, "You have already cast the bronze cannon twice, I believe you are already familiar with it." This time I hope that the artillery cast will be a light gun of one thousand to two thousand pounds. You also know that the 6,000-pound cannon is too heavy, and even if it is hauled by a horse-drawn cart, it is very troublesome, and it can only be placed on the head of the city or on the ship. This time, I hope to forge an artillery suitable for land use! ”

When Tang Long heard this, he pondered for a moment and said, "The first two times were only the first time to forge artillery, and I was afraid of making mistakes, so I would forge that big guy." Now that you are familiar with it, the marshal can rest assured that there is no problem at all! ”

Shi Jin nodded when he heard it and said, "That's good, the brothers have worked hard during this time." Those blacksmiths were rewarded with thirty taels each, and Brother Tang, you were rewarded with five hundred taels! ”

Hearing Shi Jin's reward, Tang Long hurriedly shouted: "The marshal has rewarded everyone, thank you marshal!" ”

When the more than three hundred blacksmiths heard this, they immediately shouted in unison with joy: "Marshal Xie! ”

Shi Jin said with a smile: "Everyone continue to work hard to forge better weapons and let the soldiers shed less blood!" Don't worry, as long as you work hard, I will not treat you badly! ”
