Zhang Jun is a person who has come over, and he is deeply involved in the era of cold weapons, the significance of metal armor to body protection, so next, the main task is to build iron weapons and equipment, which requires more personnel to participate, so it is necessary to send many times more people to be responsible for this matter.

Fortunately, Zhang Jun understands that there is a large amount of iron ore in Egypt, and there are several large iron ore mines in Africa, which are enough for the dinosaur clan with a population of only 2,000, and there is definitely no problem in making a set of armor by hand.

According to the memories of his previous life, Zhang Jun ordered people to continue to look for iron ore resources in the southeast desert region to prepare for future generations, because the iron ore reserves here are very rich, and the current iron mine is enough to meet the needs of the dinosaur clan for hundreds of years, and there is no problem at all.

However, with the current level of mining, only those iron ores floating on the surface can be mined, and the iron ore deep below the ground cannot be collected, and all of them are manually mined, which is very laborious.

Zhang Jun then ordered the Allosaurus team to stop training and rush to the iron ore mining area to help the Flying Dragon mine ore, and also began to build suitable mining tools for them, and the mining tools for the Great Allosaurus will also be very huge, which can increase the mining speed.

In the following period, Zhang Jun came to the scene in person, sat on an iron mine near the desert, and guided the mining work, the number of people who mined iron ore has exceeded 200, and the number of blacksmiths who are learning or making iron tools has also increased to 300, almost half of the power of the Leaping Dragon.

In addition, Zhang Jun also dispatched a flying dragon logistics detachment to help carry iron ore and tools, and the iron mine was surrounded by a large number of people, more than ten times more than usual, and iron tools and weapons began to be baked one by one and sent to Longzhai.

At this point, the war preparations of both the enemy and us are in full swing, due to the barrier of the great desert and the disadvantage of numbers, so Zhang Jun will not rashly adopt the tactics of a long-distance expedition to attack the Sword and Tiger tribe, and can only take a defensive posture for the time being, and it is the best strategy to wait for work.

More than half a year has passed, and at this time, Zhang Jun's subordinates have created more than 3,000 metal tools, weapons, and equipment, totaling more than 3,000 pieces, including 2,000 weapons, some of which are used for current equipment and some for backup use.

One of the longest time to build a number of armor, so far, has created a hundred sets of armor, is specially created for the flying dragon, these armor is also after several tests and improvements in the early stage of the product, worn on the body, the total weight of more than forty kilograms, equivalent to about a quarter of the weight of the flying dragon, although a little heavy, but the protective area covers the whole body, is an out-and-out iron bucket armor.

The rest of the armor could not be completed for a while due to different designs, and now it can only meet the needs of the Leaping Dragoon and the three infantry teams.

These weapons and equipment, because they were created in a hurry and when the technical conditions were not mature, so there were uneven slag all over the body, but the handle was smoother, and the blade edge was far less smooth than the weapons of the previous life, and the sharpness was also discounted to a certain extent, but it was more than enough to deal with wooden spears and stone tools.

On the grass, rows of shiny iron armor shine on the Leaping Dragon Warriors, they are still training hard, all kinds of fighting skills have to be retrained after wearing armor, after wearing armor, the body is incapacitated, so every move and style will be affected, and they must step up training.

The iron bucket armor on the Flying Dragon has the strongest protection for the chest, back, head, and face, and the armor thickness is also the thickest, and even iron tools are difficult to cut through, and the primitive wooden spear has no effect.

The roars of rows of warriors training could be heard on the grass, and sometimes the sound of horses' hooves could be heard from not far away, which was the cavalry team practicing horse combat skills, usually using spears and sticks without spears for combat training, and in wartime they would be replaced with real knives and real guns.

The underage dinosaurs in the dragon village are also stepping up training, they can not go to the battlefield yet, but once they grow up, they can immediately go into battle, the policy of the dinosaur clan is a soldier has been well implemented, any healthy dinosaur, can become a fierce and unparalleled warrior.

Zhang Jun walked out of Longzhai, he took five big alien dragon guards, out of Longzhai, the road has been paved at the entrance of Longzhai, these roads can be wide to take carts, about ten meters or so, there are vehicles carrying materials on the road shuttle back and forth, stirring up pieces of dust, if it is not necessary, the usual use is a carriage, once an emergency war, the four-wheeled cart pulled by the giant beast must go into battle.

These vehicles are simple in construction, but solid, and the main consideration is the load capacity, a small car can pull hundreds of kilograms of goods, and a large car can pull several tons of supplies.

Zhang Jun and the guards have changed a lot now, it turns out that Allosaurus does not need weapons, they directly attack the enemy with claws and teeth, and the lethality is the strongest, and now with metal weapons, the lethality of weapons has exceeded the body, so Zhang Jun has created a new type of weapon for the Allosaurus team.

He and the guards used a long knife that was different from the previous life, this kind of knife is ten meters long and weighs more than a thousand catties, if this kind of big knife is a flying dragon and a sword tiger, a person can hold it, it is already considered a strong man, and for Allosaurus weighing about three to five tons, this is only about one-sixth of their weight, not very heavy, equivalent to a hundred pounds of people, holding a knife weighing more than ten pounds.

And the thousand-pound big knife, using a double blade, can cut people on both sides, the tip of the knife is a sharp thorn, can also stab people, and the blade is about three meters long, can sweep a large area, which will greatly enhance the lethality of Allosaurus, in short-distance combat, their claws and teeth are still sharp weapons that cannot be ignored, and they can also be equipped with short swords.

Originally, this kind of knife was supposed to be more like a sword, but the sword did not have a long handle, and it was not used to cut people with both hands, so it was more appropriate to call it a knife.

Zhang Jun carried his big knife, which was ten meters upright, it was almost an irresistible weapon for the Flying Dragon, and they couldn't fight against such a huge long knife unless they fought in close combat.

When Zhang Jun walked along the road with five guards to the training ground, the Allosaurus team had already started drills, more than half of them were armed with long knives, and several people were armed with swords and axes about five meters long, and a few were holding spears and halberds.

What the black skin is holding is a huge axe, the length is nearly eight meters, it is the longest in the axe, the huge axe weighs more than five hundred catties, an axe can go down, can split a big tree about one meter thick, the power is amazing.

The bald head is holding a sword, the big and small Al are holding the same knife as Zhang Jun, and Qili is holding a spear, each holding a weapon and playing tricks on the training ground, and the wind is whirring.

PS: The next chapter of this book is the VIP chapter, which are all paid chapters, and I hope you have the ability to support it as much as possible. It takes a lot of effort and time for authors to write books, and it is really difficult to achieve good results without the support of the majority of readers. I hope you will give us your strong support, and I will try my best to write a more exciting plot.
