With the completion of the third branch city, Luo Ji named it 'Iron Wall', which means copper wall and iron wall, impregnable, plus Zhao Pan, the general who defends the city, personally sits in charge, this name is unexpectedly quite appropriate, although it is more Luo Ji's expectations for this third branch city.

After all, the distance is really a bit hanging, one-way journey, at least three days, in case a player invades and invades there, the Tiebi tribe is really dangerous, Luo Ji hopes that the Tiebi tribe can survive this difficult period, with such expectations, he gave the third branch city the name 'Tiebi'.

"Hmm! It's finally done! Sitting in his boss's chair, Luo Ji stretched his waist hard, and among the more than forty people, he found two talents with a single attribute upper limit of four stars.

One is a talent whose intelligence ceiling has reached four stars, and his talent is a 'herb master', no need to talk nonsense, and he is decisively thrown into the medical department, and the other is their tribal leader, this tribal leader made Luo Ji a little surprised, because his attribute to reach the four-star upper limit is 'spirit'.

Unlike other attributes that are relatively clear effects, spiritual attributes are there, and it's really hard to figure out what the use is at once, but in fact, every attribute is very important.

Spirit, can also be understood as willpower and energy, people with a high spiritual level are not easily affected by negative effects, and at the same time, the will is also firmer, of course, these are only collateral effects, the most affected by the spiritual level is work efficiency!

The higher the mental level, the higher the work efficiency, for example, you have just done the same thing, and the other person who started at the same time as you will do it well, this is the difference in work efficiency.

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

To get back to the point, in addition to the spirit, the four attributes of the tribal leader's bravery, intelligence, endurance, and command have also reached the level of three stars, to a certain extent, this is already a fairly comprehensive talent, but the natural skills are the same management development as Zhou Tao, to sum up, this should be a workaholic with management talent!

However, Luo Ji didn't directly throw him to the Black Rock Tribe, after all, he was a newcomer, and his loyalty was not even up to standard, how could he give him so much authority all of a sudden? Not to mention that there are still important coal resources on the Black Rock Tribe's side, so stay by his side as a deputy and assist him in handling the daily affairs of the Spiegel Tribe.

After arranging all the more than forty new manpower, Luo Ji has expanded his military strength a little, in recent months, the frequency of his expansion of military strength has been slightly higher, but there is no way, there are more and more territories, and they are getting bigger and bigger, if you want to hold these territories, then your military strength must rise, otherwise it is useless to run your territory well, and the enemy forces will knock you down as soon as they come.

Correspondingly, with the rise of military strength and population, the food problem of the entire tribe began to give Luo Ji a headache again, and this period of time was a little difficult, in desperation, Luo Ji enabled a special plan for a special period, and sent two archer teams formed by recruits to assist the hunting team in hunting, so that they could help hunt more prey while training archery, as for the risk that the skill tree might be crooked, he pinched his nose and admitted!

Maintaining this state, half a month later, the Tiebi tribe pushed two wooden carts to transport back the first batch of copper ore mined.

Luo Ji and other copper ore can be said to have waited for a long time, in the days of waiting, he took a lot of effort to build the forging furnace, bellows and various forging tools according to the design drawings, and also selected the candidates, and set up the 'forging department', and even the content of copper casting, he has already instilled in the members of the forging department in advance, basically waiting for the copper mine to be mined there, and then transported back for them to practice.

Waiting day and night, he finally waited for this batch of copper mines, no nonsense, and started work directly, in the case of a forging furnace and bellows, and with coal as fuel, there is absolutely no problem in terms of temperature.

The forging furnace began to ignite, and with the twitching of the bellows, the temperature in the furnace began to rise continuously, and the members of the forging department had obviously practiced countless times in the days they were waiting, and they were extremely skilled in doing it one by one, but the focus was on the after.

When he picked up the first piece of copper ore and was about to throw it into the forge furnace to heat it, the member of the forging department was obviously full of nervousness on his face, and even glanced back at Luo Ji who was standing behind.

Sensing the other party's gaze, Luo Ji raised his hand, "Don't worry about failure, every half a month after that, the Iron Wall Tribe will regularly transport copper ore over, although you can rest assured and boldly try, there will be no problem." ”

Aside from all kinds of details and technology, to summarize simply, the ancient casting technology is not complicated, roughly divided into two kinds, one is forging, and many people have the impression of forging forging method, that is, first the metal ore that needs to be forged is heated and soft, and then the blacksmith through the forging hammer in his hand, hammer by hammer to forge the metal ore into the shape he wants.

The second is the inverted mold, to put it bluntly, it is to chisel out a mold first, then burn the copper ore into copper water, and then pour it into the mold, and finally cool it into shape.

The two methods are put together, there is no need to think about it at all, the quality of the sword forged by thousands of hammers is definitely better than the second method of saving trouble.

But the second method is not useless, because it is highly efficient, and it is used to manufacture military weapons and equipment, although it is not too good in quality, but it is more than enough for the casting of some daily necessities.

At the same time, the copper coins that Luo Ji wants to issue are obviously minted by the second method, otherwise the hammer will have to be smashed into the Year of the Monkey?

He has already taught all the content that can be taught, and he actually has nothing to give advice to the members of the forging department, but he is always not at ease if he doesn't look at it a few times.

Listening to the system prompts in his mind that unlocked the 'Bronze Casting Technique' and 'Forging' items, and then looking at the people in the forging department who gradually entered the state after getting his own encouragement, Luo Ji nodded with satisfaction.

Without bothering them, he quietly left the forging department, and then he had other things to do, since the forging department had begun to cast copper, it was time for him to sort out and digest the framework of the business system with a huge amount of information.
