Su Lun doesn't have too many items that can add attributes. It's best to have as many as possible.

Pick up the Beidou Tianjiang, Su Lun looks up and takes it. A little cool energy diffuses in the body, and soon it integrates into the body.

"Congratulations, your physique has increased by three points."

Open the system to check. On his personal panel, the original constitution of 25 has become 28. After moving his body and adapting to the sudden growth of his physique, Suellen began to prepare to make a hydraulic forging machine.

The production of hydraulic forging machine is not difficult, because there are two rivers here. Each river has plenty of water. There is no problem in building a hydraulic forging machine.

Su Lun drew all the parts of the hydraulic forging machine, and then asked his craftsmen to make them according to the drawings. To put it bluntly, this thing is that the water flow pushes the water wheel to provide power, and then uses the steering device to convert the power provided by the water wheel into the hammering force of the forging hammer. The most critical part is actually the conversion device, but it is also very simple to put it bluntly.

The waterwheel is equipped with a concentric axle. The short beam on the axle moves the forging hammer to make the forging hammer fall together for hammering. This is the simplest hydraulic forging hammer. Suellen improved it by changing their speed with gears, so that the hydraulic forging machine can adjust the speed and hammering force.

The craftsman level in sulun territory was fairly good. In addition, the structure of hydraulic forging machine was not complex, so under his guidance, a hydraulic forging machine was completed two days later.

"Let's start!" Suellen took a deep breath and looked nervously at the freshly baked hydraulic forging hammer in front of her.

"Open the gate!" a craftsman shouted. As the sound fell, the sluice opened, and the surging river rushed to the river. The surging river rushed into the excavated waterway and soon rushed to the waterwheel. The heavy waterwheel was driven by the water flow, and then turned slowly.

With the rotation of the waterwheel, the forging hammer connected with it began to lift slowly, and soon the heavy forging hammer was lifted to a high enough position, and then crashed down.

"Bang!"

The sound of gold was deafening and sparks splashed.

Then the forging hammer lifted again and fell down.

"Bang bang!"

The dull metal crash continued to sound and soon became one. An iron ingot is hammered and deformed under the forging hammer in water, and the iron ingot becomes tight with the naked eye.

It didn't take long for the iron ingot to be forged into steel ingot. Su Lun picked up the ingot from Bruce and bumped it with his hand. It was full of weight and not bad in toughness. Although it was not as good as the fine steel he obtained from the system, it was not much worse.

"Ding! The construction of hydraulic forging machine is successful. Hydraulic forging machine is integrated into blacksmith shop."

[hydraulic forging machine: This is a machine with ingenious design. The machine does not have too complex structure. It successfully uses the power of water flow to forge weapons and equipment. Production efficiency + 3, steel quality + 1]

Seeing that the system recognized the hydraulic forging machine, Su Lun was also very excited. With this hydraulic forging machine, the production speed of the blacksmith shop increased three times.

"Well done. I'll use this steel ingot to produce 35 sets of two handed axes and armor," Su Lun said with satisfaction.

"How long will it take to build it?"

"Sir, at present, blacksmiths are all apprentices except me. Their skills are still lacking, so the speed of making armor..." Bruce hesitated.

"I'll give you half a month. With the hydraulic forging hammer, the difficulty of forging weapons and equipment has been reduced. If you can't do it yet..."

"Please don't worry, sir. I promise to finish the task." sullen's words made Bruce feel very angry. He didn't have any bargaining idea and agreed immediately.

"Well, I'll give you the equipment drawing later and make it according to the shape on the drawing." Suellen waved his hand and motioned Bruce to leave, then opened the system interface and drew down the equipment of the barbarian axe warrior in the system.

Now that he has the conditions, he is ready to replace the barbarians with the equipment recommended by the system. Soon after Suellen finished drawing the drawing, he asked someone to send it to Bruce.

After the first hydraulic forging machine was built, the hydraulic blower was put on the agenda. With the experience of hydraulic forging machine, the production speed of this blower was faster. In only one day, this blower was announced to be completed.

The hydraulic blower is used, which is more than the previous manual blower, two meters high and three meters wide. This blower requires at least ten slaves to cooperate with each other to operate. However, driven by the waterwheel, the blower was easily driven.

"Wheeze! Wheeze!"

Alternating back and forth, a large amount of heated air is sent to the red blast furnace, and the boiler temperature, which was originally very high, rises again. The heat wave was rolling, and several slaves near the blast furnace were red and sweating, but they were soon evaporated dry by the surrounding high temperature.

A large number of shoddy weapons and some scrap iron are sent to the blast furnace, which is soon heated, reddened, and finally softened and liquefied.

[hydraulic blower: with the help of hydraulic operation, the blower is simple in structure and ingenious in conception, which can improve the furnace temperature. Working efficiency + 2, flame temperature + 2]

With the hydraulic blower, the temperature in the blast furnace is raised again. The higher temperature speeds up the melting of pig iron and ore, and the speed of ironmaking is increased by one section in an instant.

With the addition of hydraulic blowers and hydraulic forging machines, the output of this blacksmith shop in sulun continues to increase. Although there is only one blacksmith shop, the supply territory is more than enough.

Forging, quenching, grinding, in the blacksmith's shop, Bruce took several blacksmith apprentices to forge weapons and armor in an orderly manner, and a steel bladed two handed axe specially made for barbarians was rapidly formed.

Su Lun picked up a two handed axe that had been made. This axe was made according to Su Lun's drawings. The two handed axe purchased by the kingdom of Florence was made according to the body shape of ordinary people. The two handed axe has a short handle and much lighter weight. It is a whole size smaller than the axe in Suellen's hand.

In fact, barbarians are not very easy to use, and the weight of the axe is a little light. The average mountain height of these barbarians is 2.1 meters, which is at least 30 cm higher than that of Florentine. The weapons made according to Florentine body size are not suitable for them.

Now this two handed axe is completely made according to the body shape of barbarians, which is very suitable for them. These two handed axes weigh up to 30 kg, and only the strength of these barbarians can be used freely.
