Find problems, find answers, and solve problems in practice.

In the past few days, Xiao Yu has repeated this process in Lilliputian and reality, and he only feels extremely fulfilling.

He relied on his good habit of asking professional forum experts if he didn't understand, and the good craftsmen invited by General Babu, and finally built the first collapsible giant stone throwing machine in Lilliputia.

The whole machine is composed of 50 standard parts, and the key parts are all luxuriously made of wrought iron fasteners, which are folded up to five meters long and can be carried on wheels to move forward, and can be built as an eight-meter-high stone thrower on the spot when attacking the city and grabbing the ground.

In Lilliputia, this catapult was an epoch-making war machine, not only easier to transport than the catapults and ballistae that were mass-equipped at the same time.

The most important thing is that the effective range of this catapult exceeds the distance of 800 meters of the ballista of the war machine, which is currently the longest-range, reaching an astonishing 2,500 meters!

If you're throwing an object that's lighter than a standard stone projectile, there's room for an increase in range!

Moreover, Xiao Yu used a lot of mathematical knowledge and classical formulas when training the artillerymen, so that the attack accuracy of the stone thrower was much higher than that of the ballista.

As for the catapult with a range of three or four hundred meters and a mess of accuracy, it is even more unnecessary to compare.

And when the stone throwing machine was successfully developed, relying on the large amount of wrought iron brought by Xiao Yu to start the assembly line manufacturing parts, General Babu's plan to attract barbarians also succeeded with the help of Xiao Yu's rice.

After promising two full meals a day during his time in the army, and five grains of rice for each enlistment, fifty or sixty thousand barbarians arrived from all directions in a short time.

These barbarians have been struggling to survive in the wilderness, and how many years have passed, and the barbarians who survive in the vast wilderness have never exceeded 100,000 people!

The old, the weak, the sick and the disabled among them were almost spontaneously eliminated by the cruel environment, and nature itself formed a constraint on the barbarian population, so as to cultivate their habit of looking down on life and death, greedy for immediate gain, but keeping their promises.

It's not that no tribe came here with the idea of robbery from the beginning, but after seeing Xiao Yu, the protector of the kingdom more than a hundred meters high, these barbarian tribes were much more honest.

"Let me see, is this a list of supplies that will be needed tomorrow?" Xiao Yu would stay in the camp until the evening every day and then go back, and the next day he would bring the supplies needed for the camp.

"Barbarians' weapons and armor require a lot of wrought iron, this is simple, how can it be enough to pull a hundred catties."

Xiao Yu whispered, and suddenly thought of his wallet, which was becoming more and more shriveled.

In order to facilitate the transportation of materials, Xiao Yu bought an electric tricycle, which saved Xiao Yu a lot of effort, but the wallet was almost at the limit, and Xiao Yu wanted to buy large items again, but he was afraid that he would have to swipe his credit card.

However, after returning home and sorting out the information taken by the camera with the computer, Xiao Yu felt that it was worth it!

In the past few days, Xiao Yu has paid dozens of catties of rice and wrought iron, but it is not without harvest.

After knowing that Xiao Yu was interested in the cultivation methods of human beings, An Rike offered the secret book of the royal family's knightly cultivation.

At the same time, the knight cultivation cheats that could be collected in the world were also sent to Xiao Yu, and Xiao Yu controlled the camera to scan the past page by page.

By understanding the secret cultivation method of the knights of Lilliputian, Xiao Yu roughly understood its principle of action and the basis for obtaining extraordinary power.

However, he was not in a hurry to cultivate, because according to the instructions, ordinary people who want to become knights not only need a large amount of material supplies, but also need special knight-level drugs when cultivating, they should also conduct a test of their own attributes, and only after understanding themselves can they choose the right path to step into the extraordinary.

Otherwise, there is a danger of going mad!

Xiao Yu already has such a big advantage, where would he take risks for temporary convenience?

When the royal capital is captured, use the special instruments of the royal capital to detect the attributes and then cultivate.

It's a pity that wizards are too mysterious, at least too mysterious.

In the realm of the Steelland Kingdom, in addition to knowing that wizards either live in seclusion or belong to a certain academy, practicing witchcraft not only burns money more than knights, but also attaches more importance to personal understanding and innate qualifications! The rest of the information is mostly blank.

Not to mention being able to get the practice of wizards.

Xiao Yu was not angry, in his opinion, as long as he really became the protector of the Gangdu Kingdom as planned, he was afraid that those wizards would not give in?

But when it comes to wizards, you really have to keep an eye on them.

The spells of wizards are strange, and there are not a few strange effects, and I have heard that the mana of official wizards is several times and dozens of times that of wizard apprentices. If you are not ready, if you capsize in the gutter, it will be a shame!

Back at home, Xiao Yu rested, first prepared the materials to be transported tomorrow, and then sat in front of the computer, sorting out the information collected today into a document.

Customs, hearsay, aristocratic customs and family system of the Gangdu Kingdom.

After Xiao Yu edited the information into categories, he thought about it and opened a secret document.

"Five hundred years of rumors involving wizards and suspected world wonders in the Kingdom of Steel...... How can there be no reason for this, these rumors will more or less involve the abilities mastered by these wizards! ”

Xiao Yu cheered up, guessing the rumored truth while watching, looking for a way to deal with them.

On the side of the royal capital Iron Furnace City, under the prestige formed by the Grand Duke of Yanan for many years, a large number of noble private soldiers, outlaw mercenaries and even reinforcements from non-human tribes gathered together and organized into legions under the officers of the Grand Duke of Yanan.

In the farms on the outskirts of the royal capital, a large number of horse-drawn carts pulled grain out of the cellars for military rations.

The blacksmith shop is in full swing crafting a new type of oversized armor-piercing arrowhead.

The arsenals that had been stored for many years were also opened one by one, and as dozens of responsible persons were beheaded, many arms dealers were held accountable, and a large amount of weapons and equipment were taken out to arm those hard-working mercenaries.

At the same time, boxes of gold and silver coins were carried directly on the school grounds, and the cronies arranged by Grand Duke Yanan distributed them on the spot.

As for the former quartermaster, he was hanging from the city gate tower waiting to dry.

On the highest watchtower in the royal capital square, looking down at the endless continuous military camp below, Grand Duke Yanan was full of spirit:

"Wizard Marfa, my dear friend." He said to a white-robed wizard beside him, "See, this is the essence of my Yanan family!" ”

"In the entire kingdom, I am the only one who can gather so many troops! And rule over them! ”

"Me! He is the true king of this kingdom! ”

"If one legion is not enough, then use two! Three! Or even ten legions to deal with! ”

"If 3,000 people are not enough, then use 10,000! 10,000 people is not enough...... That's 100,000 people! ”
