"As for the candidates who will go with you this time, I have already chosen them, and at the same time, there are now seven wolf warriors and three ordinary warriors stationed there in the location where the branch city needs to be established, and then I will let them stay there and be responsible for protecting the security of the branch city." There was no nonsense, Luo Ji directly spread out the map and pointed out to Zhou Tao the location where the city needed to be established, "This is this place." ”

"After the establishment of the city here, you have only one main task, then dig this coal ......" As he spoke, Luo Ji put the piece of coal he brought back in front of Zhou Tao.

Zhou Tao subconsciously picked up the black stone in front of him, and then found in the next second that the palms of his hands that had touched the black stone were dyed with obvious black, "This is?" ”

"This thing is called coal, and it is a very important fuel, simply put, it can be used instead of wood to make fires, and the wolf warriors guarding there will explain to you the specific situation." Speaking of this, Luo Ji took a sip of water and breathed a sigh of relief, "As for the tools needed to dig coal, I will let people send them over as soon as possible, you don't have to worry about the food, I will send a few people to deliver food to the branch city every few days, and at the same time carry the dug coal back to the Spiegel tribe, of course, if there is any accident, it is really a last resort......

Luo Ji said as he swiped his finger on the map, "This location, there are still crop resources in this area, you can dig some white radishes for emergency first, it is not far from the location of the city, I want to say that this is all for the time being, do you have any questions?" ”

"Do you want to leave early tomorrow morning?" Zhou Tao plans to confirm the time.

"Yes." Luo Ji nodded seriously, "You should also feel it, the temperature has dropped significantly recently, according to this momentum, the weather may get colder and colder, I just said that this kind of coal can replace wood to make a fire, it can burn longer, and the temperature is also higher, so, considering the change in the weather, I want to supply coal in the tribe as soon as possible." ”

"I understand, there is no problem for the time being, and if there is any problem in the future, I will ask the person in charge of transporting the ingredients to bring me back."

"Hmm." It's easy to talk to smart people, Luo Ji nodded with satisfaction.

Looking at Luo Ji who was sitting in the tent after Zhou Tao left, the corners of his mouth couldn't help but hook up a curvature, and the expression on his face revealed a trace of joy that could not be concealed, just now, Zhou Tao's loyalty rose by five points at once, that is to say, at this time, the other party has officially become a loyal minister whose loyalty has reached ninety points.

As the only member of Quanluo with management and development talents, it is obviously a happy thing to be able to brush Zhou Tao's loyalty to 90 points.

However, Luo Ji was not happy for too long, there were still many things that he needed to be busy with, so he immediately made a list, confirmed the people he planned to send to the coal mine one by one, and then asked people to notify them one by one, so that they could be mentally prepared.

Under Luo Ji's rapid adjustment, everything was so orderly, the development plan of the entire tribe was on track again, and at the same time, for the sake of convenience, he did not forget to choose a name for the newly established branch city.

Although he is not good at choosing names, please rest assured that Luo Ji will not be so careless to give a branch city a random name such as 'coal tribe', although at present, the characteristics of this branch city are the output of coal resources......

In this way, after a little pondering, Luo Ji named this branch city 'Black Rock', coal, black stone, so it is called 'Black Rock'.

I don't know if it's because of Zhou Tao's rich development experience, coupled with the fact that his natural ability is playing a role, the development of the Black Rock tribe is going very smoothly.

According to Luo Ji's previous prediction, all the coal that could be picked up or dug with bare hands in the periphery was picked up by the people of the original tribe, and if their tribe wanted to continue to obtain coal resources, they could only expand the mine and spend a lot of time digging it slowly.

However, the actual situation was that less than five days after the establishment of the Black Rock Tribe, Zhou Tao had people come back with a basket full of coal.

To tell the truth, according to the size of the tree vine basket, even if it is a full basket, it is actually not much, but it still makes Luo Ji feel a surprise, which is at least a good start.

The days passed day by day, and during this time, in addition to confirming the progress of fortifications and farming every day, Luo Ji focused the rest of his time and energy on the research and development of bows and arrows, however, the research and development of bows and arrows did not go smoothly at all......

Looking at another broken bow, Luo Ji frowned slightly, and his mood looked a little bad, "Isn't this okay?" ”

Rubbing his eyebrows vigorously, he found that the difficulty of developing the bow and arrow was far beyond his expectations, and this feeling of being stuck in a bottleneck, not knowing how to break through, and finally completely stagnating made people both irritable and panicked.

"What went wrong?" He has tried almost all the materials he can find nearby, but the effect is not ideal.

Of course, when drawing the bow, if you leave a little bit of force, you can still do it, but the light arrow is not half powerful at all, it is no exaggeration to say, fifteen meters away, he is standing there, let the bow and arrow shoot over, the eye may still hurt a little, but if the shot is the torso of the body, the arrow can not cause any substantial damage at all except for the pain that can make him feel a little pain, it is a complete failure!

Grabbing the hair that had become a little messy, Luo Ji tried to find the problem and the cause, but found nothing, and finally could only come to a conclusion, that is, 'maybe the material of the bow body is not suitable'.

Well, it can't be denied that he was frustrated in the research and development of bows and arrows, Luo Ji is not a brainless person, after clearly realizing that he could not solve this problem in a short period of time, he slowly regained his cool head and patted his forehead gently, "Don't worry, take it step by step......"

After speaking, he took a step back decisively, in all senses, he has realized that in this era when there are no long-range attack weapons at all, he wants to make bows and arrows as soon as he comes up, and there is a little bit of the meaning of wanting to run before he learns to walk, so he has taken a step back now, planning to learn to walk first.

He quickly picked up the charcoal he had tossed out a few days ago, and then spread out a blank animal skin and buried himself in drawing another design drawing.

This time, he didn't draw for too long, nor did he get too entangled, he got the design drawing in almost three or two clicks, and then stretched out his hand in front of the five members of the ordnance department, "Let's put the research of the bow and arrow first, let's do this next." ”
