Faced with this kind of problem, when he was not sure, Luo Ji decisively opened the friend list, sent a message to Gao Su, and gave a brief explanation of what happened to him.

About five minutes later, Gao Su gave him an affirmative answer, allowing Luo Ji to confirm that his analysis was correct, although there is no limit to the cooldown time of this skill, it really doesn't let you use it casually, it seems that every time you use it, it will cause a certain degree of consumption to the body, and if you use it too many times in a row, you may have symptoms such as 'body detachment, dizziness, and splitting headache', of course, how many times you can use it depends on each person's attribute panel and physical fitness.

Feeling that he was dead, he looked up at the sky, judging from the position of the sun, the time should be one or two o'clock in the afternoon, the whole person was dizzy, and he didn't have the energy to deal with affairs, dragging his head that seemed to be filled with several catties of cement, Luo Ji planned to go back to the camp to take a nap.

However, before going to bed, he didn't forget to call someone to inform Luo Jin, and let Luo Jin take his reconnaissance team in the direction to reconnoiter the barbarians who appeared today.

In the past few days, after inspecting the work progress of various parts of the tribe every day, he took his own literacy cards to teach the children in the tribe to read, and by the way, he also triggered a 'text' cultural project.

Looking at the effect, it turned out to be a self-produced and self-sold project to increase cultural points, and the depressed Luo Ji hurriedly asked Gao Su, where is the role of developing cultural projects? Or what is the use.

After this question, from the reply sent by Gao Su, Luo Ji found that this role is really a lot, first of all, the good development of culture can improve the basic intelligence of many people in the civilization, and at the same time, when giving birth to offspring, it can improve the probability of the emergence of intellectual talents, this alone is enough to persuade Luo Ji to develop culture.

Second, when more than 70 percent of the population in a city has received cultural education, the livability of the city is +1

Finally, technological development projects can only be unlocked after the culture has developed to a certain point......

Looking at the last one, a hint of understanding flashed on Luo Ji's face, yes, if the civilization is full of illiterates, then how can science and technology projects be developed? At this moment, Luo Ji suddenly strengthened his determination to develop cultural projects.

At the same time, he also enjoyed the whole process of teaching the children in the tribe to read, especially when he gave them homework homework. This is a pleasure that springs up from the bottom of my heart!

A few more days have passed, and during this time, the Spiegel tribe, which has always been quite stable, finally ushered in a major event, and the fortifications that Luo Jina had built for several months were finally nearing completion!

Hearing the report of the construction team, Luo Ji's whole mood was obviously excited, it is not easy to build a city wall in this era, and he has worked hard for many months, and he can't help but wipe a handful of bitter tears when he thinks about it.

This will protect the entire Spiegel tribe, along with a piece of the outer area, and there is only one last step left before it is completed, and that is the installation of the city gates!

This step obviously requires Luo Ji to do it himself, after all, in this entire city gate structure, a set of pulley block mechanisms is needed to drive, except for Luo Ji, other people in the tribe obviously can't figure this out, as for letting Luo Ji teach these people who haven't even graduated from elementary school to learn junior high school physics, forget it, just thinking about it, the brain starts to hurt.

After assembling the mechanism of a whole roller skating group, with the installation of the city gate, a whole circle of outer city walls was suddenly connected together, controlling the excitement in his heart, Luo Ji raised his hand and signaled the people of the construction team to start turning the two wheels placed in the city gate.

The two men who came out of the team glanced at each other, as one of the members of the construction team that made this city gate, how heavy this city gate was, they knew in their hearts that when they carried it, they were more than a dozen adult men working together, and it was not easy to move here.

Although the city gate was made according to the design drawings, they could not imagine what such a heavy city gate would have to do to open it again once it was closed.

"Do it, hold that grip, and turn the wheel in front of you." Looking at the two of them standing there stupidly, not knowing what to do, Luo Ji explained a little.

Out of loyalty to Luo Ji, although both of them felt a little inexplicable in their hearts, they still did it honestly, holding their hands on the long grip, and then began to exert force at the same time, but the wheel in front of them was basically not moving, which made the two of them subconsciously glance at Luo Ji's location, "Leader......"

"With all your might, don't worry about breaking it, this thing isn't that fragile."

Hearing Luo Ji's words, the two exchanged a look, and began to exert force on the wheel again, and it was obvious that the muscles on their arms were constantly bulging, and under the impetus of this force, the wheel that had not moved at all before finally moved, began to rotate slowly, and then pulled the pulley group to start running......

With a sound of 'click, click, click' into the ears of the two, before they could look back, a burst of irrepressible exclamations came from the mouths of the nearby onlookers, "The city gate, the city gate has risen!" ”

"Rising?" At this time, the two people who were facing away from the city gate and pushing the wheel with all their might were stunned at the same time.

After they turned the wheel to the limit, and then according to Luo Ji's instructions, they stuck the wheel with the buckle that had been prepared on the side, and the two of them who couldn't wait didn't have time to take a breath, and hurriedly turned around to look at the city gate behind them. It's really rising?! ”

Looking at the city gate rising high, at this moment, even if the facts were already in front of them, the two of them still couldn't believe that their eyes had really risen? The city gate, which required a dozen people to barely lift, was raised by the strength of the two of them just now?

How exactly is this done? It's really incredible, everyone who doesn't know what the 'roller skating group' is, can only keep marveling at the magic of this scene in front of them, and looking at Luo Ji's eyes, they also become more reverent.

System Prompt: Congratulations to the player 'Luo Ji' for building the 'Ancient City Wall', and the 'Spiegel' tribe has +1 livability
