Shen Luoyan put the star-shaped iron into a graphite crucible. This crucible was specially used for melting metal and was found in the monastery. It can withstand a high temperature of 3,600 degrees, which is enough to melt the star-shaped iron.

The high-temperature beam she released continued to shine on the star-sinking iron block.

After absorbing a large amount of heat, the star-sinking iron gradually became red-hot.

The red-hot star-sink iron oozes molten iron like sweat, and finally the whole piece melts into liquid.

Shen Luoyan continued to illuminate the beam, maintaining the temperature in the crucible, and poured the molten iron into the mold.

She will first make the star iron into grinding discs and grind the holy silver into fine powder particles.

Although holy silver is relatively soft, it is also much tougher than ordinary steel. A millstone forged from ordinary metal cannot grind it into powder at all.

She installed the grinding disc on the lathe that had been assembled earlier, and then closed the iron shell to prevent the ground holy silver powder from flying around.

Holy silver is much more expensive than gold of the same weight.

She rubbed her brows and used her spiritual power to control the rotation of the gears.

The grinding machine immediately heard the harsh sound of metal grinding. Even though star iron is much tougher than holy silver, grinding it is not easy.

"What shape of weapon do you need?"

Shen Luoyan asked.

For a warrior, the shape, center of gravity and angle of the blade are all very important. Some schools will also inherit a special shape of weapons to match the secret martial arts in the school.

"Let's make it the original shape of the Yanling sword, but the blade should be longer, preferably 1.2 meters, so that it can compete with the heavy two-handed sword without falling behind. The weight should be more than 20 kilograms, preferably 1.2 meters. It’s about thirty kilograms.”

Li Mu thought for a moment and then said.

The weight of the knife is very important. If it is too light, you will be very weak if you want to cut into enemies with strong defenses, and half of the cut will be blocked by those tough tendons and bones.

Shen Luoyan took out a notebook and drew a sketch with a pencil. He calculated the various dimensions of the long knife.

She chose the blade angle at 25°. Although the star-sink iron is extremely tough, in a battle between awakened people, the impact force exerted on the weapon would even exceed one hundred tons in a single collision.

If the blade angle is too small, although the blade of the long knife is sharp enough, it is likely to break directly during the battle.

A thick enough blade spine can also absorb the impact of a collision and increase the weight of the blade.

As for the problem of not being sharp enough, it can be easily solved. The Qi method of the strengthened awakened person has been cultivated to a certain level, and it is almost indestructible. The ability to destroy and cut is far more useful than a simple blade.

It took Shen Luoyan more than three hours to grind all the approximately five kilograms of holy silver into fine powder.

Because it was starch iron, it was even more difficult to grind starch iron pieces with starch iron grinding discs. It took her more than ten hours, with several breaks during the period, to grind out enough starch iron powder.

She took a sip of the Sun Fountain to regain her energy before starting the next step.

Accurately weigh the amount of powder, put it into a blender according to the formula proportion, and mix evenly.

Pour the evenly stirred metal powder into the crucible, Shen Luoyan took a deep breath, and instantly released a blazing psychic beam with its highest power.

The destructive beam is converted into ultra-high heat energy, and even the graphite crucible with extremely high melting point is baked red-hot.

The metal powder in the crucible was burned to death by the high temperature

She picked it up with a graphite rod and picked out a hair-thin wire from the crucible. In this way, she turned all the metal powder into holy silver and star-sink iron alloy wire.

After checking all the metal wires on one side and confirming that the yield was good, Shen Luoyan breathed a sigh of relief, took a nap for two hours, regained his energy, and continued the next work.

Directly using metal powder for sintering will have the disadvantage of insufficient fatigue resistance, and is more likely to have defects such as looseness, pores and lack of fusion. These defects are very likely to cause the weapon to break directly during high-intensity battles.

That's why Shen Luoyan chose to make alloy wires first, and then use high-temperature beam sintering to make weapons while weaving them.

The weapon integrated in this way, due to the specific weaving structure, not only has superior toughness, earthquake resistance, and high temperature resistance beyond the alloy itself, but also has extremely high transmission efficiency for spiritual energy. Even if ordinary steel is used, it can Create a weapon with superior performance, let alone forge it directly with spiritual metal.

This method requires a high-power laser transmitter, and the weaving parameters need to be changed according to the shape of the weapon during manufacturing.

Even before the Cataclysm, only large-scale research institutes could manufacture such weapons in small batches. After the Catastrophe, even high-level awakened people cherished the weapons fired in this way.

Wrapping all the alloy wires around seven spindles, Shen Luoyan used his spiritual power to control the seven alloy wires and quickly weave them on a rotating cursed blood iron plate.

The spindle was whirling, and the alloy threads as thin as spider silk were woven and wound in complex techniques. Shen Luoyan continued to sinter them together directly with ultra-high-temperature psychic energy beams.

She replaced the industrial computer with her own thinking, and single-handedly achieved functions similar to those of various large equipment in the laboratory.

Amidst the whirling sound of the spindle, Shen Luoyan spent more than an hour sintering out a small section of the knife handle.

She wiped the sweat from her forehead and was about to continue working when she noticed that Li Mu and Li Mu were looking at her with inhuman eyes.

"What's wrong?"

"You are really a human, not a robot pretending to be a human."

Li Mu said after looking at the half of the knife handle with a matte surface.

"The Shen clan has a secret meditation method that can peel off part of their own thinking to act as a computing unit to perform fast floating-point operations. Now I can perform 1 billion operations, which takes about 12.8 seconds."

Shen Luoyan continued to sinter the metal wire.

"One of the indicators that measures the strength of the awakened manipulator is the speed of floating point calculations. The faster the calculation speed, the more flexible and precise the control machine is. When I use the mechanical arm to assist you in combat, it is through high-speed calculations that in a few milliseconds Mobilize the robotic arm to match the movement of your arm muscles. Otherwise, a slow-responsive robotic arm will become a hindrance."

Li Mu hugged his shoulders, and then glanced at Li Mei, who was peeling oranges next to him:

"It seems that I am not suitable to be an awakened manipulator."

"I don't think this ability is anything to be envied at all." Shen Luoyan said while waving his fingers to sinter the metal wire.
