The capital city is very big, Liu Ye distributed all the built houses to the city residents for free, and the ground is cement floor, such houses are equivalent to the structure of the seventies and eighties of the Chinese country in the past.

Asphalt roads also began to be paved, and the asphalt used in the capital was not quite the same as it was before the war. This is a kind of earth-made asphalt, which has been used in the past to pave roads, and the effect is not bad.

Liu Ye hated the muddy appearance of the capital city when it rained, and he didn't use walking and warrior reactions very much. Anyway, there are so many such resources in the wasteland, he paved all the roads where the people lived in the city into asphalt.

The ruins and everything were cleaned up and replanned, and from a distance, the place where the current residents of the capital lived looked like an old-fashioned community. In addition to the lack of greenery, all the major facilities are available.

There is electricity and water, a stove with a special 'door' and a personal bathroom, as well as their own rooms. The room is free to arrange their favorite furniture according to their own ideas, and the citizens of the capital city have never enjoyed this kind of treatment, and they all feel as if they have entered heaven.

The appearance of each person's room makes people pay attention to the importance of privacy and sexuality, know shame, know respect for others, and have a sense of responsibility. The basic moral outlook automatically appeared in the hearts of the city people, and this kind of social morality was the most deeply rooted in the hearts of the people, which was much better than the regulations imposed by Liu Ye.

During this period of time, it can be said that it has completely reached the social situation of not closing the house at night and leaving no roads behind in ancient times, but Liu Ye does not think that this situation will last long, he still orders the guards around him to keep a close watch.

After all, the human heart is the most fickle, the most persistent, and the most changeable contradiction.

The rest of the asphalt and cement, Liu Ye painted all the four walls of the capital, which greatly increased the degree of solidity, even if it was bombarded with artillery, it would not be easily broken.

At this time, Liu Ye got the news that a military industry that had just been born had also achieved results.

There was a loud bang, and the people covering their ears saw a small hill in the distance half blown away.

"Such a big force, Liu Ye is the black fire 'medicine' that was developed? It's almost as powerful as a tank artillery! Nan Tiancheng looked at the explosion just now excitedly, turned his head and shouted loudly.

"Hey, be quiet, my ears are not deaf by the explosion, but I'm going to be deaf!" Liu Ye frowned slightly, took a few steps away and said.

"I have long wanted to make gunpowder, I have always used the stock of the past, and one day it will run out, and only by making it myself can it last long!" Liu Ye fanned the oncoming black smoke with his hand.

"Not bad! Everyone now uses grenades to tighten the 'trousers' belt, after all, there is one less with one, who knows what large-scale wars will be encountered in the future! Nan Tiancheng nodded in agreement.

"This test is considered passable, you look at this very powerful, but you notice how much gunpowder we used to blow up that little hill! That's the size of a three-year-old child! ”

Liu Ye is not too satisfied with the current results, you must know that no one can carry such a big bomb to kill the enemy all day long, and that kind of weight will greatly reduce the mobility.

And the target is too big, I'm afraid that before the bomb is thrown on the enemy, I will be finished because the bomb is hit by the enemy.

"Alas! It's powerful, but it's not practical! Liu Ye shook his head, sighed, and prepared to leave.

This fire 'medicine' Liu Ye is a fire 'medicine' measured by using a test tube made by the girls, although the accuracy of the 'fine' has been improved a lot, but there is still an error of 0.1 to 1. This error does not seem to be large, but when it is used to measure moles, it is 108,000 miles away.

Liu Ye had already taken the error into account, but he could still only make a bomb the size of a three-year-old child.

"Liu Ye, you say this thing is useless? But I think this bomb is very useful! Nan Tiancheng heard Liu Ye's sigh and said strangely.

"Oh?" Liu Ye turned around and asked Xiang Nan Tiancheng: "You say this stupid thing is useful?" ”

"That's right! Have you forgotten the ordinance issued a month ago? Ask the citizens of the city to compete with each other, and if you become the first in each field, you will be given a great reward! Nan Tiancheng nodded and replied.

"Of course you remember? How could it be that there is a weapon that can be used to use this stupid thing? Liu Ye was a little hard to believe, how long had he just been talking, and a new weapon came out, could it be a tank or a self-propelled artillery?

In Liu Ye's eyes, there are only two weapons that can apply this kind of big guy, but unfortunately those two are still too far behind the current steel manufacturing level in the capital.

"Liu Ye, do you know the weapon of the catapult?" Nan Tiancheng smiled mysteriously.

"Catapults? Know! What do you mean by using a catapult to 'fire' this cannonball? Liu Ye was stunned for a moment, and immediately understood, but at the same time he shook his head and said: "Yes, it can be, but the direction of the catapult 'shooting' range is constant, and it cannot be changed at will, which is greatly disadvantageous!" ”

In the last days, humans have to face not only their own compatriots, but also mutated creatures, most of which are very agile, and catapults can only carry out one round of strikes at most, which is really worth the loss.

"Liu Ye! That's in the past, and we used that thing in the capital before, but because it was too clumsy, and it was more 'wasteful' and abandoned! But this time it's different! This developed catapult is not ordinary! Nan Tiancheng squeezed his eyes at Liu Ye and said with a smile.

"Not ordinary? What's not ordinary? Let me see! Liu Ye immediately demanded.

"Come with me, even if you don't say it, I'll let you come!" Nan Tiancheng turned around and walked towards the city, and Liu Ye followed with curiosity and excitement.

Nan Tiancheng is not the kind of person who has no knowledge, and he still dares to say this after seeing the current problems, which shows that he is indeed confident that he can make good use of the bulky bomb developed by the new entrant.

"Hello city lord, good Nan-sama!" The city's citizens greeted Liu Ye and Nan Tiancheng warmly, and they thanked Liu Ye from the bottom of their hearts for the changes they had brought them.

"Hello everyone! Well done! Keep up the good work! Liu Ye and Nan Tiancheng hurriedly replied, encouraging the people of Xiacheng by the way.

"It's here! This is it! How about you look at this new type of catapult? Nan Tiancheng walked to a city house and pointed to a huge device in front of him and asked.

At the front of the house is a 10-meter-long wooden utensil that resembles a giant slingshot, and at the back is an animal skin bag for stone projectiles. The leather pouch is tied with a thick rope, and when it is needed, it can be untied to send the stone projectile flying out with elastic force. Some of the townspeople were pointing around the catapult, very curious.

"That's it?" Liu Ye took a closer look at this device, which was a little different from an ordinary catapult, and asked.

"That's right! That's it, don't underestimate it, this catapult has been modified by the makers with reference to the shape of those tanks! Nan Tiancheng said with confidence.

"Retrofit according to the principles of a tank, just a carpenter?" With saws and some half-finished timber hanging in front of the house, Liu Ye could see the identity of the maker at a glance.

"Yes, it's carpentry! This carpenter is different, other carpenters like to make household utensils, but he is very 'fascinated' by catapults and siege equipment! I've been thinking about these things all day! Nan Tiancheng said.

"Siege equipment?" Liu Ye suspected that his ears had heard it wrong, the ancient siege equipment was not simple, and this book could be made by himself with a carpenter?

Seeing Liu Ye's expression, Nan Tiancheng smiled, and he shouted loudly towards the 'door' of the house: "Don't believe it? I didn't believe it at first, but after seeing it once, I had to believe it! Lu Ban came out and showed our big city lord the attack power of this catapult! ”

"It's coming! A young man in his twenties ran out of the house covered in sawdust, holding a freshly made wooden peg in his hand.

"Your name is Luban?" Hearing that Huaxia was called the Zuluban of carpentry, Liu Ye had a ridiculous feeling, and he asked.

"Yes! Castle Lord! The young man named Lu Ban nodded respectfully and said.

"Who gave you this name?"

"Back to the city lord, it was his subordinates who started it themselves!"

"You made it yourself?" Liu Ye felt even more interesting: "Do you know the meaning of the name Luban?" ”

"My lord! I know that Lu Ban is the ancestor of carpentry in Huaxia! Lu Ban looked up and replied.

"You know?!" Now it was Liu Ye's turn to be surprised, and he asked excitedly, "How do you know?" ”

"City Lord, these things are what I saw from this book!" Lu Banyang raised the book he was holding in his other hand and replied.

"Show me!" Liu Ye brought the book and looked at the title: "Detailed explanation of ancient military equipment!" ”

"I see! Luban's name was you got from the book? Liu Ye was relieved.

"Yes, Lord Castle! I thought that the person named Luban was very amazing, and I wanted to be like that, so I changed my name to Luban, and the people around me said that my name was changed well! Lu Ban said with confidence.

"It's not just amazing, Lu Ban is a fairy in the eyes of carpenters!" Liu Ye looked at the energetic young man in front of him and felt a feeling in his heart.

"Good! I like aspiring youth, now can you tell how to modify this catapult? ”

"Yes, City Lord! I saw that the barrel of a tank could move on its own and that it could be adjusted up and down, and I wondered why catapults couldn't do that! ”

"So you added a wooden turntable and gears to the catapult?" Liu Ye had already seen these two devices, and when he heard Lu Ban say this, he immediately understood in his heart.

"That's a good idea, but let's demonstrate it!" Liu Ye ordered everyone to withdraw this catapult from the 'gate' of the city, and prepared to test the power of the hill in the distance.
