Chapter 250 (1/2)

The bow handle of the reverse curved bow generally only plays the role of stability and shock absorption, and will not participate in the deformation and force storage in the process of opening the bow, so it can be made of wood or metal materials.

However, what Zhang Che needs to customize is an appalling super bow. If metal materials are used, it is necessary to add many precious minerals from the animal world to the bow handle. In this way, the price is too expensive.

Using wood is different.

Although wood that can withstand this strong stress is rare even in the alien world, the price will not be too outrageous.

The selection of the bow piece is a little more troublesome when the Millennium pole wood is selected.

Because this material store did not display exotic materials suitable for Zhang Che's needs.

In other words, because it is almost impossible for anyone in the world to use a strong bow with a full string tension of thousands of kilograms, the materials suitable for production are put in other display areas and sold as other materials.

However, the customer is God. Since Zhang Che needs it, the material store will soon measure the specific elasticity of high-grade materials suitable for making bow pieces according to Zhang Che's needs.

In less than an hour, Zhang Che saw what he wanted.

A pair of seven-star silver quality Toxoplasma gondii's double horns, elastic enough to reach nearly 3000 kg; The elasticity of the ribs of two six-star gold exotic animals just meets Zhang Che's needs, about 2000 kg.

In a word, the internal space of the Amethyst turtle still has a part of the ribs of the Titan python, which is also the top material for the bow piece.

Unfortunately, the Titan Python is a six-star dark gold quality beast. If the bow is made of its ribs, such a strong bow, whether Zhang Che or skin monkey, is simply unable to open at present.

Zhang Che can only hope that one day when the tension of his arms can reach more than 10000 kilograms, it is estimated that he can re customize a real super strong bow with the ribs of the Titan python.

Will the arrows from a super strong bow with a full string pull of tens of thousands of kilograms directly break through the sound barrier and exceed the speed of sound?

Zhang Che estimated that it was very possible, because the speed of shooting arrows from the falling star bow he had used was not far from the sound speed.

Although the distance from approaching the sound speed to approaching the sound barrier and finally breaking through the sound barrier is not as easy as expected, tens of thousands of kilograms of super strong bow, combined with specially customized arrows, should also meet the requirements?

At the thought of this, Zhang Che looked forward to it deeply.

Of course, if you want to reach tens of thousands of kilograms, it is not a task that can be completed in a short time. During this period, you don't know how much exotic meat you need to eat.

Unless Zhang Che is lucky, he can steal a batch of eggs from other animals like poisonous fire double headed dragon to eat.

But that's something you can't ask for. Many exotic animals regard their eggs more important than life. How can they be found so easily.

Zhang Che shook his head secretly. It's better to customize two strong bows first. Use them first. Later, when the opportunity comes, it will be natural.

Although the three goods were only materials, they eventually cost Zhang Che a huge sum of nearly 10 million union dollars. Of course, he didn't have so much money in his own account. He didn't dare to move the money in sun Che's account. Didn't he let people find out that sun Che had something to do with himself?

Fortunately, Zhang Che also had a large number of exotic cards. After learning that he could barter, he directly took out two four-star silver exotic cards and got what he wanted.

After buying the materials, Zhang Che and Huang tielan rushed to a large nearby weapons and equipment manufacturing company and customized two reverse bows at the cost of a four-star silver quality alien card.

Because Zhang Che's customized strong bow is too demanding this time, the other party said it will take at least five days to complete.

In the next five days, apart from staying at home with his mother, Zhang Che was almost inseparable from iron man and girl. He visited the whole northern city and bought a lot of all kinds of things.
