After breaking the cottage, Liu Jun used the fastest speed to move all the people in Lijia Village to the mountain, the terrain of the stone slope is certainly not as good as Wuhu Mountain, the only good place is convenient transportation.

Wuhu Mountain is very inconvenient, and the materials are all carried by people and horses, and dozens of stones of grain are transported up the mountain, so all the manpower on the mountain has to be moved.

"This problem has to be solved, and it is a low-cost solution, do you have any proposals?" The Juyi Hall, where Chen Hu and other bandit leaders were shot to death, was renamed a school for the first time, and the best building in the cottage is the school, which shows that Liu Jun attaches great importance to education.

Of course, this school does not teach the four books and five classics of qin, chess, calligraphy and painting, but teaches some practical skills and thoughts.

Now the school can't get enough students, so it was temporarily borrowed by Liu Jun to discuss the future development of the cottage with everyone, Liu Jun's children, the orphan girls of the cottage, and all the boys and girls under the age of 14 in Lijia Village stood on the side to observe.

Liu Jun's question was a bit vague, hoping that the children who were listening could also use their brains to think.

What else can be done other than people carrying horses? Liu Jun also added a sentence of 'low cost', isn't it a cheap way, in this way, even horses can be saved, the cost of horses is too high, donkeys and mules are the same, they all belong to large animals, that is, only people are left to carry one way?

looked at each other for a while, and finally Li Maojin said: "The powerful prime of life on the mountain are all dead, so I can only pack the heavy objects and move them up little by little, there is no other way." ”

After a pause, he said: "The mountain has been like this all these years, you see our house on the mountain, except for this ...... The school, the other houses are low and narrow, and the shelves are not high, just because the big wood can't be moved. ”

In the end, Li Maojin's tone was already full of bitterness, obviously he had suffered a lot over the years.

Liu Jun looked at the others, either avoiding her gaze and bowing his head silently, or shaking his head, and finally, Liu Jun's gaze fell on Zi Qingshu's body.

Ziqingshu's injury has generally improved, and he has no problem sitting and walking, except that he can't exercise vigorously.

Originally, there was no need to invite him to participate in such a development meeting, but who made him idle and bored, so he had to come to participate, looking at Liu Jun on it, he had a smile on his face, and he didn't know what to think of and kept nodding his head there.

This caused Liu Jun to misunderstand what he meant, looked at him and asked, "What good idea does Zi Gongzi have?" ”

Zi Qingshu shook his head embarrassedly: "No, I have everything for Zilong and them to take, so I don't have much experience, you can ask them, Zilong Zihu, hey, what about Zihu?" ”

After laying down the cottage, Zilong and these people took Ziqingshu to the mountain for the first time, for fear that he would be in any danger, and someone would follow him at any time, usually Zilong and Zihu followed, but Zihu didn't know when it was gone.

Zilong buckled his nose and turned his head away with a flickering gaze.

Ziqingshu was a little surprised and asked, "Do you have something to hide from me?" ”

Zilong looked at Liu Jun for help, and Liu Jun said: "Zi Gongzi, it's like this, the children lack nutrition, and you are recovering from your injuries, and you also need nutritional supplements, so Zihu went into the mountains to hunt." ”

Wuhu Mountain is just a small hill on the edge, and to the southwest is a deep mountain and old forest, stretching for hundreds of kilometers, and Wuhu Mountain is just the edge of this big mountain range.

If Liu Jun has the ability to organize people to hunt in the deep mountains and easily solve the food problem, why do you need the idea of fighting bandits?

However, the danger of the deep mountains and old forests is far greater than that of these half-baked bandits in Wuhu Mountain, not only fierce beasts and poisonous insects, but also ground-type dense forests and miasma torrents, which can kill people.

Purple Tiger has a lot of experience in the mountains, so he came to Liu Jun yesterday to ask for that set of climbing equipment, and offered to exchange it for prey.

Zihu's proposal really made Liu Jun unable to resist, he was too short of meat, because of the barbarians, Lijia Village was looted, and other villages were no exception, the county was closed, the supplies were cut off, and the children had not eaten soy products for a long time.

Protein is the most important substance for growth and development, and other things can be eaten less, but protein must be sufficient, otherwise it will not grow meat.

Soy products are cut off, so they can only find ways to supplement them from the meat aspect, but the thieves are as poor as ghosts, and there is a little bit of bacon jerky, so there is no need to think about anything else.

Purple Tiger's proposal Liu Jun couldn't refuse, otherwise what would it matter if he gave him a set for nothing?

Zi Qingshu's suspicious gaze roamed back and forth on Liu Jun and Zilong, trying to see if they were hiding something from him. But Liu Jun also said that Purple Tiger went into the mountains to hunt for his nutrition, so he didn't have to suspect anything, otherwise it would hurt Purple Tiger's heart too much.

Seeing that Childe no longer asked, Zilong quietly wiped a cold sweat.

Continuing to return to the original topic, Liu Jun saw that everyone had no better proposals, so he simply said his thoughts: "Even if the mountain road is difficult, then we don't take the mountain road, let's change places and lift the materials up." ”

"Hang up?" Liu Jun's words made everyone scratch their heads, but after she brought the sand table up, everyone knew it at a glance.

"This is where we climbed up, and it was almost 90 degrees steep, and we built a rack here and hoisted things up with a pulley. In this way, we only need to build a simple gravel road here and here, which can be used by large vehicles. Liu Jun said.

Is that okay too? Everyone thought it was a little strange after listening to it, what is a pulley block? Can you lift heavy things?

The wooden pulley group is covered with copper-clad wooden shaft, which is wear-resistant and has certain self-lubricating characteristics, and the friction coefficient is also very small after being smeared with animal grease.

Two days later, a wooden shelf was built on the cliff that Liu Jun and the others had climbed when they dived, and two people stirred the turntable, which was toothed and could be reversed, which meant that it could only rotate forward, and it would get stuck when reversed, unless the clip was removed.

In this way, even if you lift a heavy object, it will not cause the item to fall and break because of getting rid of it.

It wasn't until the pulley crane was formed that Zi Qingshu looked at the entire device and said thoughtfully: "This thing seems to be the device used by the Broken Dragon Gate of Wuding City, how can Liu Dangjia be so clever in mechanism?" ”

Wuding City is an important border town, there are only two city gates, each of which has a broken dragon gate weighing 10,000 catties, as long as it encounters danger, cut the rope to put down the broken dragon gate, directly seal the city gate, prevent the kind of thing that can be driven straight into the city gate to prevent the kind of thing that can be driven straight into the city gate can happen.

The device for suspending the broken dragon gate is very similar to the crane in front of you.

When the first basket of test stones was easily twisted up by two people, all the original bandits couldn't help but let out a cheer: "It's time to build a big house, it's time to build a big house." ”
