Jiang Feng knew very well in his heart that the strongest attack power was only relative.

The most rigid things are suitable for breaking the surface with points, and the softest things are not suitable for breaking the surface with points.

For example, in the face of a pool of water, attacking one of them will have no effect.

Only by blasting the pool in one fell swoop can the water scatter in all directions.

In the face of a big iron ball, the attack of breaking the surface with points will have the effect of getting twice the result with half the effort.

Under even force, even if the attack power is strong, it is difficult to hurt the iron ball.

"Attack cohesion and attack dispersion, each has its own role!"

After careful calculation, Jiang Feng once again found that he still lacked a magic weapon.

The faster the knife is sharpened, the less effort it will take to cut things.

The Ninth-grade alloy long knife was extremely sharp, but due to the lack of strength of the material, it could not carry his formidable strength.

The strength of the body is high, and the palm is not thin, so it is difficult to exert the power of the force!

"At present, the best weapons on the Earth's side are all made of ninth-level alloy."

"The quality of the weapons produced by machinery is about the same."

"By the way, the Dragon God Star must have a divine weapon!"

After thinking about it, Jiang Feng locked the door and summoned the pharmacist trading platform.

"Brother Jiang." Li Qiang exclaimed with a happy expression.

"I want to build a magic weapon, but I still need materials and casting skills." Jiang Feng said.

Through the other party's dictation, he can get the casting technique of the Dragon God Star, as for whether he can get the materials from there, he doesn't care very much, whether he has it or not, it's a big deal to find materials on the side of the Earth Star.

The drug dealer trading system can only trade drugs, medicinal materials, medical books and other things, however, plants can be used in medicine, animals can also be used in medicine, why can't minerals be used in medicine? Almost everything in heaven and earth is medicine.

There are good medicines and poisons, and many metals are poisonous, so it seems that those poisonous metals are poisons!

"Brother Jiang, wait a minute." Li Qiang said.

"Hmm." Jiang Feng nodded.

Ending the video call, Li Qiang walked to the treasure building.

"Xiaoqiang, are you here again?" Li Yongxiang, who had a normal breath, greeted with a pleasant face.

"Third grandfather, I'm here to find something." Li Qiang said with a smile.

"Whatever you want, I'll get it for you." Li Yongxiang said.

"Third grandfather, I'll find it myself." Li Qiang said with a smile.

"Hmm." Li Yongxiang nodded.

Walking into the treasure building, Li Qiang selected three of the best casting techniques and took more than a dozen top-level materials.

"Xiaoqiang, what are you doing with these?" Li Yongxiang asked suspiciously.

"Third Grandfather, the way of cultivation, one by one, my strength has improved too quickly, and the foundation is inevitably unstable, I want to study the casting technique." Li Qiang said casually.

"That's fine." Li Yongxiang nodded with a satisfied expression.

Back in the room, Li Qiang locked the door and put more than a dozen top-level materials into the pharmaceutical trading platform.

Through the other party's dictation, Jiang Feng wrote down three casting techniques, gave the other party ten fifth-grade body elixirs, and obtained six pieces of ore that exuded a metallic luster.

"Brother Jiang, Xingchen Gold can't be traded." Li Qiang said.

"It's fine." Jiang Feng said disappreciatively.

"Brother Jiang, someone is coming, let's contact us next time." Li Qiang said.

"Okay." Jiang Feng nodded and ended the video call.

After pondering the three casting techniques for a while, and after thinking about it, he went to the Martial Arts Bureau in Yunshan City to buy some meteorites.

"There are no forging tables, forging furnaces, cooling pools, forging hammers, forging pliers."

When he came to the weapon shop, Jiang Feng, who had a lot of money, directly ordered a ninth-grade alloy forging table and a forging hammer......

"Cooling water is very important, high-grade cooling water can enhance the performance of weapons!"

After recalling the cooling water in the Dragon God Star Casting Technique, he found that he couldn't find it on the Earth Star, and after thinking about it, Jiang Feng went to buy two refrigeration equipment and more than a hundred catties of the best cooling oil.

"When you get your order, you'll be able to try to build weapons!"

After pondering for a moment, Jiang Feng walked straight to the library and quietly flipped through the works on metal smelting.

In summary, whether it is a hand-built weapon on the side of the Dragon God Star or a weapon produced by a machine on the side of the Earth Star, the materials are alloys, in order to learn from each other's strengths and improve the various properties of the materials.

Cast iron is too broken, but it becomes resilient when it is made into steel.

Steel is going to rust, and stainless steel hardly rusts.

Gold is too soft, add some other metal, and the hardness will increase.

Of course, alloys made from several high-grade metals may not perform as well as steel.

Jiang Feng knew very well in his heart that the difficulty of creating a divine weapon was not small, and it could not be achieved overnight.

After reading for more than two hours, relying on his ability to remember at a glance, he wrote down more than a dozen books on metal smelting word for word, and after looking at the time, he walked away from the library.

"Scrap iron can be turned into steel, why aren't people like this?"

The core of the three casting techniques obtained from the Dragon God Star is to fold and forge again and again, quenching certain different materials into a mixed material, and then quenching them with a specific coolant.

"My current strength, I'm afraid that there are more than five million catties, and the long knife that is about to be forged must be widened and thickened, otherwise, I won't be able to withstand my huge strength, so I will design the long knife first!"

Walking into the weapon shop again, Jiang Feng picked up a long knife with different shapes and tried it out.

"The front is light and the back is heavy, which is not conducive to chopping."

"The front is heavy and the back is light, and the strength of the blade is insufficient."

"The center of gravity is uncertain, isn't this a pit man?"

After buying a long knife that was the most comfortable and pleasing to the eye, Jiang Feng quickly left the weapon shop.

"Just use this knife as a kind knife, make it thicker and wider."

Three days later, everything ordered was made.

After renovating the forging room, Jiang Feng threw all kinds of materials into the forging furnace.

"It's faster and easier to heat up than in ancient times."

In less than ten minutes, the materials began to melt.

After all the materials were melted, Jiang Feng stirred them evenly, and when the mixed materials were initially solidified, he picked up the forging tongs, clamped them to the forging table, and wielded the heavy forging hammer, and beat them with appropriate weight.

"Ding, ding, ding!" The sound sounded, and sparks bloomed.

The impurities in the ore flew off one by one with the beating of the forging hammer.

Jiang Feng, who has strong strength and long endurance, only took half a day to create a kitchen knife.

took out a ninth-grade alloy kitchen knife, and slashed hard with both knives, breaking the kitchen knife in two.

"The ratio of various materials is not suitable, the number of folding and forging is too small, and the power is not as good as that of the ninth-grade alloy!"

After returning the broken knife to the furnace, he put some more materials, and after noting down the proportions of various materials, Jiang Feng continued to forge......

"The power is comparable to that of a ninth-grade alloy kitchen knife, and it is far from my requirements!"

A few days later, Jiang Feng held a freshly baked kitchen knife in his hand and slashed hard at a ninth-grade alloy kitchen knife.

"It's much stronger than a ninth-grade alloy kitchen knife, but it can't hurt the scale armor of the Tyrannosaurus rex, come again!"

This morning, Jiang Feng found the Tyrannosaurus Rex and said, "Batian, give me one of your teeth." ”

The bones, teeth, and horns of high-grade alien beasts are high-quality additives that can improve the strength and toughness of weapons.

The Tyrannosaurus rex is a tenth-level beast of the earth and gold series, and the things on its body are definitely the best additives.

"Boss, what do you want my teeth for?" Batian wondered.

"Why don't you give me a little bit of the horn on your head?" Jiang Feng's eyes lit up and he said.

"Boss, I still have a single horn in my house." Baten said.

"Whose horn does it belong to?" Jiang Feng asked.

"It's one of my elders." Baten said.

"Go and get it for me." Jiang Feng said with a smile.

"Hmm." The Tyrannosaurus rex nodded, whipping its wings into the air.

In less than an hour, it flew back with a single horn.
