During these five days, Liu Fei was very busy, and he was designing and manufacturing some simple and practical cold weapons, among which the main one was a weapon - the tip of a long spear.

The so-called spear tip is the metal thorn at the front end of the spear, which is a main weapon designed by Liu Fei for the residents of Wei Jiaji, with a length of thirty-five centimeters, and an extremely rare "Han Jin" at the tip, and there is a small amount of reserves on the Brave Enterprising, which is very hard after melting into an alloy with iron in a certain proportion, comparable to diamond.

Liu Fei has done many experiments, this kind of spear can easily pierce the armor of the gladiator's heavy ironclad cavalry, and the spear does not require too much skill to use on the battlefield, as long as you master some basic steps.

As long as the spear is loaded with fine wood, it can become a murder weapon, in the grassland, in addition to the weeds is a shrub that grows in patches, the shrub is about two meters high, very thin, Wei Jiaji people are commonly known as fine wood, the fine wood is slightly thicker than the baby's wrist, hard but not hard, soft and not broken, can be bent to 180 degrees without splitting, strong flexibility, its own fiber density is thick, there is a strong natural tensile force, the texture is light, very suitable for making a gun, when the spear was originally designed, the application of materials was also taken into account.

In fact, the spear designed by Liu Fei is not called a spear, but called a three-page gun, which is very different from the traditional spear, Liu Fei has spent a lot of thought, the front end of the three-page gun has three blades, which are extremely sharp and abnormal, and have extremely lethal destructive power.

Of course, the triangular sharp edge is not only to amplify the enemy's wounds, it also has a more important function, it has passed the wind tunnel simulation of the light brain, has very excellent aerodynamics, and if the spear is thrown, it can maintain a very stable flight trajectory.

Liu Fei's workload is very large, he has to make weapons for 37,000 people in five days, which is tantamount to a difficult task.

In fact, Liu Fei wanted to make far more than 37,000 spear tips, at least more than 100,000 spear tips, because he equipped each of the 37,000 people with five spear tips.

However, this is not a problem for Liu Fei, in fact, he does not need to do it, his main job is design, because, the casting task is all handed over to Boehleigh, in the Brave Enterprising, the manufacture of this small-sized cold weapon is simply pediatric, and the materials are not a problem, he only needs to use a hovercar to transport it to Weijiaji.

During this transportation, Liu Fei selected 500 nimble teenagers from Wei Jiaji and sent them to the Brave Enterprising for some simple training, so that they could learn to operate some of the simplest machinery from Burleigh and cultivate them step by step.

When selecting these five hundred people, it caused a sensation in Wei Jiaji, because these five hundred people will take the iron guy who can fly in the sky to study in a more mysterious place, which attracted all the teenagers of Wei Jiaji, and the entire Wei family of children between the ages of fifteen and eighteen signed up for the exam organized by Liu Fei.

Liu Fei's method is very simple, mainly through some intelligence tests to calculate their IQ, and then choose the winner.

There are more than 8,000 teenagers who participated in the intelligence test, and more than 3,000 people are qualified, however, the Brave Endeavor is currently unable to accommodate more people, Liu Fei only selected the best 500 people, and the other 2,500 people are under Wei Xiong's command to carry out some physical training, once the Brave Enreavor needs it, they can go there as soon as possible.

During this time, Wei Xiong, who was the busiest, had to assist Wei San in training 32,000 people, and he also had to train his own 5,000 people, plus 2,500 teenagers arranged by Liu Fei.

Fortunately, he only needs to arrange the training according to the steps arranged by Liu Fei, but he doesn't have to do it himself.

Wei Chongyang and Mei'er are mainly for administrative management, organizing the major tribes into an army and dealing with the contradictions between them, which makes the two miserable, these people are not as easy to call as the residents of Wei Jiaji, however, the two are not too worried, from Liu Fei's words, the two also realized that they can't expect those tribes to win this first real war, and at the same time, the two also understand that the current resources of Wei Jiaji cannot meet such a huge army expenditure, Even the weapons that soldiers need most are in short supply, and many soldiers have to find a way to solve them on their own.

Day 5 has finally arrived!

The people of Weijiaji breathed a sigh of relief, because it was easy for people to lose patience and lose their fighting spirit after waiting for too long, and the food crisis in Weijiaji had become more and more serious......

In the early morning of the fifth day, 300,000 people flocked to the direction of Nancheng like a tide, crossed the Nu River from dozens of pontoon bridges that had been built long ago, divided into three routes of soldiers and horses according to the degree of relationship between the various tribes, and marched to Nancheng in three ways, from Weijiaji to Nancheng There is a distance of nearly 200 kilometers, according to the marching speed of 50 kilometers a day, it will take at least four days, and the tribal leaders agreed to launch a general attack in the early morning of the fifth day to surround Nancheng from three sides......

When the 300,000 troops rushed to the south of the city, the 37,000 elites of Weijiaji also left Weijiaji with the flow of people, but they did not embark on the journey, after crossing the Nu River, under the cover of one of the armies, they walked several kilometers upstream along the Nu River, and found a low-lying terrain to lurk unconsciously.

"From now on, all the residents of Wei Jiaji will retreat!" Liu Fei glanced at the smoke and dust in the distance and said lightly.

"What?" Wei Chongyang thought he had misheard.

"After we leave, take all the food with us, and immediately evacuate all the inhabitants to the swamp, and I have arranged for people to pick up there."

"The troops of the Southern Military District will sneak up on us?" Mei'er's face changed dramatically.

"Yes, remember, you can't leak the news, if the news is leaked, you can't disperse the forces of the Southern Military District, so, after we leave, no one is allowed to stay, and those who forcibly stay will be executed!" Liu Fei said with a serious face.

"Yes!" Wei Chongyang was in a daze.

"No, this is in charge of Mei'er and Manny, and after we take the South City, Mr. Wei needs to establish a provisional government."

"Mei'er ......" Wei Chongyang showed a trace of worry on his face, you must know that there are at least more than 200,000 people in Wei's family, and most of them are old, weak, sick and disabled, and it is undoubtedly a difficult task to evacuate so many people.
