When Chen Feng was on Earth before, he served in the "Ordnance Warehouse" of a certain military region, and the "Ordnance Warehouse" was actually a research institute that researched new types of weapons and ammunition.

After collecting a lot of information about the demon beasts in the primary stage, Chen Feng learned that the bullets fired normally by an anti-tank rifle could completely penetrate the skulls of ordinary low-level demon beasts and kill the demon beasts. There has never been a weapon like a "rifle" in Daluo, and Chen Feng feels that if he is not good enough to make good use of this advantage, he will be too sorry for himself.

On this day, Chen Feng took the coins to the shop that sold weapons, spent 20 gold coins, bought a carving knife specially used to depict weapons, and then invited craftsmen in the shop who could build a miniature furnace, Chen Feng needed a small furnace that could smelt steel to refine the materials used to make rifles.

The cost of the small furnace requires 100 gold coins, and it is the same price, which Chen Feng and the craftsmen have discussed 10 days ago, after the two sides signed an official agreement, Chen Feng paid the material fee, and the craftsmen followed them to the small courtyard rented by Chen Feng, Chen Feng and the craftsmen determined the specific details as required, and then the craftsmen started to work.

Chen Feng began to take out the "Soul Melting Heavenly Gong" issued by the army, and began to study the method of refining the body, which could enhance his strength, which was exactly what Chen Feng needed.

Two days later, the craftsmen built the furnace according to Chen Feng's layout, and fired a furnace of molten iron in front of Chen Feng, and after confirming that the furnace was in good condition, they took the remaining balance from Chen Feng's hand.

A wooden shed was also built on the furnace to block the rain, and there was a high fence around the small courtyard, and the wooden shed was added to block the space for his own weapons, so Chen Feng could cast his own big killer weapon with peace of mind.

After the handover of the furnace, it was approaching the night, Chen Feng went to the vegetable market, bought a fresh mutton, prepared to cook a pot of stewed mutton to relieve hunger, but also replenish the body, eat to pay attention to nutritional matching, mountain cities can rarely buy fresh vegetables, Chen Feng bought some fresh melons and fruits instead, after all, you should also pay attention to the nutritional balance! The melons and fruits here are all picked from the mountains and forests near the east of Baiyun City, the price is not expensive, and it is quite clean, Chen Feng took the fruit and wiped it on his clothes and started eating, all the way back Chen Feng has already eaten the small half of the fruit he bought.

Began to cook his own nutritious meal, when he was on earth, Chen Feng stayed in the army's cooking class, whether it was the army's big pot rice or home cooking, the newly bought pots and pans have been cleaned, directly set up the iron pot, light a fire, put the cut mutton into the water in the pot, because it is his own food, Chen Feng, who has never been afraid of the smell of mutton, after a clear water to the pot to spice, boiled for half an hour, the broth is full of fragrant, Chen Feng can't help but eat while cooking in the iron pot, a broth belly, eat Chen Feng burped。

Eating to support his stomach reminded Chen Feng of his hard-working and simple parents, when he was a child, his father's food was too delicious, and his mother did not control his appetite, Chen Feng grew up, every meal was eaten with a round belly, and because of this, Chen Feng's physique has always been relatively fat, and later he had the idea of joining the army, so he lost weight like crazy, thinking about it, Chen Feng's eyes couldn't help but cry.

Thinking of his parents and relatives who are far away on the earth, it is impossible for his parents to know that they are still alive, how to make his parents accept the "white-haired people send black-haired people", how sad his parents should be, and even! Chen Feng thought about whether his parents would be white-headed overnight or something, Chen Feng's heart hurt so much that he couldn't breathe, no matter what, Chen Feng wanted to return to his parents and pay homage to filial piety......

Chen Feng is not afraid of anything now, only afraid that he will be able to return to the earth one day, but he will never see his relatives again, he will not be able to find his own home, when he was on the earth, Chen Feng was in the army, and he didn't have much time to accompany his parents, and now that he thinks about it, he feels that he owes his parents too much.

Willfully emptying his thoughts, Chen Feng's heart is fortunately sour, fortunately he is not an only child, Chen Feng only now finds out that it is good to have a brother with a calm personality, when he is not there, he can take on the responsibility of taking care of his parents, I just hope that my family will not be too sad, after all, I am still alive and well, and there may be a day to meet.

I don't know how long it has been, Chen Feng forcibly pulled back his thoughts, now is not the time to be sad, to turn all thoughts into motivation, go all out to do things, brave to fight is the right reason, only cowardly people will always be immersed in grief and can't pull out, in Chen Feng's world, people who dare to fight and dare to die are the real hot-blooded men.

Chen Feng rested for a while, and the structure diagram of the anti-tank rifle appeared in his mind, and he searched for the metal materials that this world could correspond to from his memory:

1. Flint powder, good stability, energy that will be burned by stamping, the energy generated is very large, it is very suitable for acting as a bullet projectile, it is a bit expensive, this material is generally used as the energy of the city cannon, it is a very precious mineral powder, to determine the good amount of waste is not wasted;

2. Black gold, which is a very hard metal, can be directly used to make bullet warheads, but black gold is a precious metal, and the money on hand is only suitable for buying a small amount;

3. Tough copper, with the characteristics of toughness and low hardness, can be gold plated for bullets, reduce the wear of bullets on the barrel, enhance the accuracy of bullets, and can also make copper wires, which are used as alarm wires.

4. Pig iron, unrefined pig iron is relatively cheap and can be purchased in large quantities, and the steel required can be refined by oneself and used as a material for making rifle bodies;

5. Soft iron, soft iron has good toughness and heat resistance, and its soft characteristics are good materials for making molds;

6. Wood, it is necessary to find a kind of hard wood to make a gun butt and gun box, and a weapon box for holding weapons and tools;

7. Rubber tree resin, good waterproof performance, strong viscosity, used to fix the bullet warhead;

8. Black sand, a sand box used to make iron grinding tools;

9. Black coal mine, which is used to smelt steel.

Chen Feng took out a pen and paper and recorded the share of materials needed one by one, 1 tael of flint powder, 10 taels of black gold, 10 catties of tough copper, 300 catties of pig iron, one side of soft iron, a piece of wooden compact mahogany board, a barrel of rubber tree resin, a pile of abrasive black sand, and a pile of black coal mine.

Chen Feng went to a shop that bought and sold metal ores, which contained all the things he needed, and the materials Chen Feng chose were all commonly used ordinary metal materials, and there was no need to deliberately negotiate the price, saving a lot of effort, and the materials were bought quickly.

Chen Feng hired a carriage to transport his goods back to his residence: 1 tael of flint powder, 10 taels of black gold, 10 catties of tough copper, 300 catties of pig iron, a soft iron, a wooden compact mahogany board, a barrel of rubber tree resin, a pile of abrasive black sand, and a pile of black coal mines, this time it cost about 37 gold coins, and there were 39 gold coins and 88 silver coins left in his hand.

All the materials and tools are ready, Chen Feng is not in a hurry to make a robbery, after all, he still needs to be proficient in casting technology, especially Chen Feng plans to use the casting method to make a rifle, the performance of the rifle made by this casting method is unstable, so it is necessary to pay more attention to every step of the details.

Chen Feng first cast a thick back (chopping knife) that is tall and tall, this is a weapon that fits the world, and it can confuse others when carried around, Chen Feng doesn't want firearms and weapons to circulate, at least for now, in addition to this weapon, Chen Feng also has to make some gadgets that need to be used when going out hunting, especially tools for handling ingredients, which is the most important thing related to making a living in the wild.

Chen Feng put the soft iron into the furnace to melt into molten iron, poured it into the two black sand sand boxes prepared in advance, the molten iron continued to flow slowly from the riser of the sand box, until the sand box was completely cooled, took out two long strips of soft iron, with a carving knife on the soft iron, depicted (chopping knife) appearance, although the line of this time is relatively simple, but because it is the first time to depict the abrasive, this process also took 10 days.

After carving out the formed soft iron abrasives, Chen Feng combined the two abrasives, put them into the sand box, and prepared the sand box abrasives. Put 100 catties of pig iron into the furnace, build the furnace fire, refine the required iron essence, pour it into the riser of the sand box uninterruptedly, wait for the inside of the sand box to cool completely, take out the abrasive, and then open it, and a clear line (chopping knife) appears in front of you.

After a round of casting and refining the weapon, Chen Feng already had a good understanding of this, and it took him two days to re-forge the blade of the sword, enhance its hardness, and polish the blade, making it a real weapon.

Chen Feng holds shoulder-high (chopping knife) with both hands, put it in front of his eyes, the whole knife is made of fine iron, the blade is more than one meter long, the knife surface is dark and wide with 3 fingers, the back of the knife has a little finger thick, the blade is clean and shiny, there is a tiger head connected to the handle under the knife body, and the handle has a small annular embossed thread.

Chen Feng held the handle of the knife with both hands, his right hand in front and his left hand in the back, and began to practice the knife posture of the knife technique: chopping, chopping, chopping, cutting, cutting, cutting, teasing, hanging, pulling, pressing, twisting, dragging, picking, cutting, racking, blocking...

Footwork exercises: horse step, lunge, virtual step, insertion, follow, leap, cover step, independent step, forward progress, backward step.

The essentials of the action during the practice of Daluo knife method: the whole body is relaxed, the lower plate is stable, the pace is flexible, the waist is the force point, the hand, the eye, the body, and the footwork are coordinated with each other, the action of the knife should be fast, clean and neat, the force should be fierce, the force point should be accurate, not dragging mud and water, dancing flowers, rotating, turning over, wrapping the waist, wrapping the neck, cloud chest, dancing back, cloud, picking, teasing, hanging, etc., should move along the circle rules, and the action of the arc connection should be smooth and round, and the speed and strength of the broadsword should be increased with the help of the potential of inertia, so as to increase the lethality of the broadsword.

On this day, Chen Feng tirelessly waved the (chopping knife) in his hand, felt the sharpness of the blade, and a domineering aura erupted from the depths of his heart.

The knife is a sharp weapon for killing, the knife holder needs to pay attention to the domineering when walking the knife, pay attention to fast, accurate, ruthless, this is the need for accumulated practice to do, daily practice of the knife in the hand, not only to make the knife in the hand more flexible, but also to increase their courage, exercise a brave heart.

Going to the Wanshou Forest to hunt powerful demon beasts, there are too many unknown unsettling factors, and entering the dense forest alone requires courage, and without a strong and calm heart, you can't go on. Fortunately, when Chen Feng was on earth, he was also put into the deep mountains and old forests in the no-man's land to temper himself, and he often drove alone on the mountain roads in the no-man's land, and also exercised Chen Feng.

In the following time, Chen Feng cast a knife sleeve for his own (chopping knife), and then began to make some other tools, becoming proficient in his own technique of casting metal utensils. Chen Feng made in turn:

7 daggers, black gold boning knives, kitchen knives, bone drills, fire knives, copper wires, machetes with long wooden handles, single-edged axes with long wooden handles, special iron pots, iron spoons with long handles, and a hammock made of thick hemp rope.

Chen Feng also has to prepare some warning bells, which are small bell parts that can be combined at any time: a bag of semicircular small iron sheets connected to two pieces, and a small bag of small steel balls. This bell can be combined with copper wire, used as a wake-up line, in the forest, when you need to use it, arrange the wake-up line around yourself, if something is close to you, break the copper wire, vibrate the bell, the bell rings, you can hear the information one step in advance.
