Start a city building order

210 Visitor

In the early morning, the torrential rain that had rained all night finally stopped, but the surrounding area of ​​the mountain city did not turn into a swamp. On the contrary, the entire mountain field became lush and lush, and various trees rose from the ground, forming patches of forests. The weeds on the wasteland Also knee deep.

As for the terraced fields, the heavy ears of wheat, corn, and corn looked very pleasing. Not only was the maturity period shortened by one month, but the yield was at least doubled.

Even if Li Si is willing, this area will be like spring all year round, and there will be no cold or hunger anymore.

This is the power of the middle-level destiny.

Even this destiny can allow Li Si to fly into the sky and hide in this area, making him a god who controls the sun, atmosphere, thunder, strong wind, ocean waves, mountains, forests, and all things and spirits.

As long as he holds the sword of destiny in his hand, as long as the extraordinary substance in his hand is enough.

It's so easy to become a god.

Even as long as he is willing, he can kill hundreds of thousands of monsters in this area in an instant. Even for a historical reincarnation like Qin Qiong, instant killing is just a matter of one thought.

Li Si has calculated that even if he does nothing, this kind of life can last for 1 years, until the extraordinary substance in his hands is exhausted.

Because now he has a total of 200 million points of extraordinary substance in his hand.

This is an astronomical number.

However, at this moment, Li Si did not feel any excitement. He still had breakfast as usual, and rushed to the No. 1 courtyard of the cemetery to continue researching the extra-large catapult unit.

In the previous battle, this kind of catapult unit made a great contribution. With physical damage, it destroyed the defense of the Thunder Light Bug Demon Boss in one fell swoop.

The most wonderful thing is that this catapult unit is in an underground tunnel, and the enemy cannot see its whole picture.

Yesterday, Qin Qiong even wanted to exchange a large amount of materials for the technology of the catapult unit, but was rejected by Li Si.

Although in his opinion, it is not difficult to decipher this kind of catapult unit. It only needs Qin Qiong to describe the general situation, and then it falls into the hands of Luban and Mozi, and it can be recovered in minutes.

"His Majesty!"

Erlund, the commander of the artisan battalion, Huang Yu and others have long been waiting here. Yesterday's battle was also their pride, and the replays after the war made them even more excited, and now they have summed up many ideas.

"Your Majesty, after our post-war review and the data obtained from the re-test firing, we have initially grasped the specific data of this new catapult unit."

Huang Yu was the first to speak, "First of all, after replacing the iron ball, although the weight has doubled, the throwable distance has also almost doubled. The farthest you can shoot is 200 meters. After adjustment, you can hit the target at a distance of 600 meters. .”

"Secondly, the projection height has been calculated to exceed 320 meters. If you can know the wind speed and direction in the air in advance, then the accuracy will be greatly improved. Basically, you can hit a circle with a radius of ten meters. Of course, it can be used to attack A single small or medium target, or a target that moves extremely fast will definitely not work."

"Then, there is power. We can only say that we can't find a reference to describe its power. As long as it hits, no matter who or what it is, it will definitely kill!"

"Finally, the suggestion I would like to make is whether the process can be further refined, so that the operator can make more precise adjustments, so that the shooting accuracy will be better."

After Huang Yu finished speaking, Erlund opened his mouth, "Your Majesty, I have a different idea. I think that the catapult unit can require improved precision adjustment, but it can never be expected that the accuracy of the catapult unit can be comparable to that of the Eight Bulls Crossbow. What do you want to point out?" This is a fallacy, so I think that the best way is to improve the rapid launch of the catapult unit, diversified strikes, and quick adjustments to more directions on the basis of improving the accuracy as much as possible.”

+-After listening to the suggestions of these two people, Li Si thought for a while and said: "Your ideas are all good, but they are too one-sided. They have not grasped the real core of the trebuchet. The power of the trebuchet is not important, what is important is This set of power transmission device, you should study this thing more, how to convert, store, and adjust the power brought by those one hundred mules."

"Only by understanding this set and understanding can we improve as a whole."

What Li Si said made Huang Yu look confused, but Erlund was thoughtful, but it doesn't matter, if you don't understand, you can learn.

This time, Li Si deliberately selected 200 craftsmen with the best growth potential, and Huang Yu didn't accept them these nights, and explained them starting from basic physics.

In fact, his set is nothing new. A hundred mules are like an engine. By using gear bearings and other structures, the effect of a transmission is simulated. Pulling each spring steel sheet group is like shifting gears, and it is the simplest shifting gear .

There is nothing technically meritorious, the only advantage is that the materials are all strengthened with extraordinary substances, and the performance is explosive.

Li Si hopes to gather the wisdom of craftsmen to further optimize and improve it.

Of course he himself got involved, because he also had some immature ideas.

For example, by enlarging the central gear set and refining the branch gear sets, the power output is finer.

Also, in addition to trebuchets, these powers can also be used for other purposes, such as siege crossbows.

If it is possible, it is not impossible to make a steam engine to replace the mule...

Well, that's not right, it doesn't need to be so complicated, you just need to strengthen these mules with strength potions, and one mule can support a steam engine.

In addition, instead of thinking about other tricks, it is better to continue to improve the power of the trebuchet.

Because as long as it is within the control range of Destiny, thunder, gusts, flames, and even meteors and falling rocks are not a problem. No matter what the source of the enemy is, the level of Destiny is lore.

Only when encountering something like the Lightning Bug Demon, which can be completely exempted from the attack of destiny, it needs to be physically bombarded with a catapult.

For several days in a row, Li Si enjoyed it and couldn't extricate himself.

To be reasonable, he felt that such a day was really good, and then he received invitations one after another.

"Ding, the ninth group of the Middle Ages invites you to join, and promises to send troops to help you quell the current world immediately. At the same time, it promises to build a historical anchor in your main city. You can communicate between the main cities through the Sunset Tavern. If you are interested, please reply."

"Ding, the Nine Groups of Rome invited you to join them. They promised to open business with your main city, and at the same time open the exchange authority of the Sunset Tavern."

"Ding, the Meng Yuan Five Team invited you to join them, and promised to give you two special arms cards."

"Ding, the Nine Groups of Song and Ming invited you to join them, but they want you to move the main city to their sphere of influence."

"Ding, Qin Han Ninth Group invites you to join them."

"Ding, Sui and Tang Nine Groups invite you to join them."

"Ding, the two Jin and three groups invite you to join them."

"Ding, the second group of the shogunate invited you to join them, and they promised to put aside any past suspicions with you, and smile away all grievances."

"Ding, Huang Zhong from Team Nine of the Three Kingdoms hopes to make an official visit in three days."

"Ding, Lu Ban, the person in charge of the Second Division of the Historical Alliance Express, wishes to visit you."

"Ding, Sun Simiao, the head of the Civil Engineering Division III of the Historical Alliance, wishes to visit you."
