With the completion of the third branch city, Luo Ji named it "Iron Wall", which means a copper wall and an iron wall, indestructible. In addition, Zhao Pan, the general who defended the city, was personally in charge. The name was unexpectedly quite appropriate.

Although this is more about Luo Ji's expectations for this third branch city.

After all, the distance is really long. The one-way journey takes at least three days. If the next player invades and invades there, the Iron Wall Tribe will be really in danger. Luo Ji hopes that the Iron Wall Tribe will

With the hope that he could survive this difficult period, he gave the third branch the name "Iron Wall".

"Well! It's finally done!" Sitting on his boss's chair, Luo Ji stretched hard. Among the more than 40 people, he found two talents with a single attribute limit of four stars.

One is a person with an intelligence limit of four stars and a talent of 'Master of Herbal Medicine'. No need to talk nonsense, he decisively throws him into the medical department. The other is their tribe leader. Luo Ji was a little surprised by this tribe leader, because he reached

The attribute with the upper limit of four stars is 'Spirit'.

Different from the relatively clear effects of other attributes, the mental attribute is there, and I really can’t figure out what its use is at first, but in fact every attribute is very important.

Spirit can also be understood as willpower and energy. People with a high spiritual level are less likely to be negatively affected, and at the same time, their will is stronger. Of course, these are only incidental effects. What is most affected by the spiritual level is work efficiency!

The higher the mental level of a person, the higher the work efficiency. For example, if you have only done half of the same thing, another person who started at the same time as you has finished it. This is the difference in work efficiency.

In addition, for players like Luo Ji, there is another important difference between the level of spirit and that is related to the number of times they activate skills!

Let’s get back to the topic, in addition to spirit, the tribe leader’s four attributes including bravery, intelligence, endurance, and command have also reached the three-star level. To a certain extent, this is quite comprehensive.

He is a talented person, but his innate skills are the same as Zhou Tao’s management development. To sum up, this should be a workaholic with management talents!

However, Luo Ji did not directly throw him to the Black Rock Tribe. After all, he was a newcomer and his loyalty had not yet reached the standard. How could he be given such a large authority all at once? Not to mention that there were still important people in the Black Rock Tribe.

Coal resources, first stay with him as a deputy to help him handle the daily affairs of the Mirror Tribe.

After arranging all the more than 40 newly added manpower, Luo Ji slightly expanded his military strength. In the past few months, he has expanded his military strength slightly more frequently, but he has no choice but to occupy more and more territory.

There are more and more territories, and they are getting bigger. If you want to defend these territories, your military strength must increase. Otherwise, no matter how well you manage your territory, it will be useless. The enemy forces will come over and beat you down.

Correspondingly, with the increase in military strength and population, the food problem of the entire tribe began to give Luo Ji a headache. Life was a little difficult during this period. In desperation, Luo Ji activated a special plan for special times and sent out

He formed two archer teams formed by recruits to assist the hunting team in hunting, so that they could help hunt down more prey while training archery. As for the risk that the skill tree might become crooked, he pinched his nose.

admit!

Maintaining this state, half a month later, the Iron Wall Tribe brought back the first batch of mined copper ore on two wooden carts.

Luo Ji had been waiting for this first batch of copper ore for a long time. During the waiting days, he spent a lot of effort to build the forging furnace, bellows and various forging tools according to the design drawings. He also selected

After selecting the candidates, he established the 'Forging Department'. Even the content of copper casting has been instilled in the members of the Forging Department in advance. Basically, he is waiting for the copper mines to be mined there and then transported back for them to practice.

.

After waiting day and night, he finally got this batch of copper mines. There was no nonsense and he started working directly. With a forging furnace and bellows, and coupled with coal as fuel, there would be absolutely no problem with the temperature.

The forging furnace began to light up, and with the twitching of the bellows, the temperature in the furnace began to continue to rise. The members of the forging department had obviously rehearsed this entire process countless times during the days of waiting, and every one of them performed it.

Extremely skilled, but the focus is on what comes after.

When he picked up the first piece of copper ore and prepared to throw it into the forging furnace for heating, the member of the forging department was obviously nervous, and he even looked back at Luo Ji who was standing behind him.

Sensing the other party's gaze, Luo Ji raised his hand and said, "Don't worry about failure. From now on, every half month, the Iron Wall Tribe will regularly transport copper ore. You can go ahead and try it boldly. There will be no problem."

."

Leaving aside various detailed techniques, in a simple summary, ancient casting technology is actually not complicated. It can be roughly divided into two types. One is forging, which is similar to the forging method in many people’s impressions. It is to first melt the metal that needs to be forged.

The ore is heated and softened, and then the blacksmith uses the forging hammer in his hand to forge the piece of metal ore into the shape he wants, hammer by hammer.

The second type is inverted molding. To put it bluntly, a mold is cut out first, and then the copper ore is burned into copper water, then poured into the mold, and finally cooled and formed.

Putting the two methods together, you don't need to think too much at all. The quality of the sword forged through repeated efforts will definitely be better than the second method that saves time.

But the second method is not without merit, because it is highly efficient and can be used to make military weapons and equipment. Although the quality is not up to standard, it is more than enough to be used in the casting of some daily necessities.

At the same time, the copper coins that Luo Ji wanted to issue obviously had to be minted using the second method, otherwise the hammer after hammer would have to be struck until the end of the Year of the Monkey?

He has already taught everything that can be taught. He actually has nothing to give advice to the members of the Forging Department, but he always feels uneasy if he doesn't take a few glances at them.

Listening to the system reminder in his mind that the 'Bronze Casting' and 'Forging' projects had been unlocked, and watching the people in the forging department gradually getting into the mood after receiving his encouragement, Luo Ji nodded with satisfaction.

Without disturbing them, he quietly left the forging department. He had other things to do after that. Since the forging department had begun to cast copper, it was time for him to sort out and digest the huge amount of information in the business system.

Framed.
