Titanium ore in the Tang Dynasty did not have an accurate term, its quality so that the smelting experience of the foundry at a glance to know that it is a metal ore, but because the melting point is too high, when there is no production of coke, the foundry can not burn these ores with firewood, so for a long time, titanium ore was defined as waste ore by the foundry, and now the situation is different, the horse has the ability to refine it, once the ore of this quality is smelted into a new metal what kind of form, all the foundries are looking forward to it.

Several casters with big shoulders and round waists are calcining titanium ore according to Yang Lin's instructions, and they heard the horse say that with the addition of this titanium, the toughness of the steel will be improved by a multiplier, even if it is a sword cast from high-carbon steel, it may not be able to break through the plate armor made of synthetic metal, Xie Wuregret did not dare to slack off, and hurriedly asked his subordinate adjutant to pass the news to the palace, just waiting for the sharpest knife and the toughest armor to be made for the emperor to see as soon as possible.

The ratio of titanium and iron is easier to grasp than carbon steel, only need to put a little bit of molten iron in the hot pot, from the afternoon until the day is dark, a pot of molten iron with a little titanium is finally poured into a small piece of plate steel, now there is no acetylene, oxygen welding, if the whole is too big, there is no way to cut, is to be directly poured into the mold of the heavy armor before.

When the palm-sized plate steel was formed and cooled one by one, the high-carbon steel knife with the most suitable proportion on Xie Wuregret's side was also successfully cast, although the appearance was very ugly and did not conform to the best form of mechanics, but after cutting off dozens of Tang knives in a row, it was also instantly promoted to the level of divine soldiers, Li Er would always appear at the right time at the most critical time, and he didn't know when his habit of listening to the root of the wall would change, which was actually a problem.

"See Majesty."

The craftsmen and supervisors in the hall of the workshop bowed down one by one, and Yang Lin also owed a debt, and Li Li, who forgot her husband when her father came, ran over in a hurry, and was hugged by Li Er, and happily rubbed Li Er's chest with her face.

"Let's get flat!"

It's not the first time that Li Er has come to the craftsman's prison, and the war in the Tang Dynasty has not stopped in the past two years, but Yanglin is not in the court, so he doesn't know much, and Li Li's quality has been crooked for a few seconds, and Li Er can't wait to see the plate steel and high-carbon steel long knives that Yanglin has refined.

"Your Majesty, this long knife is definitely the number one divine soldier of my Tang Dynasty." Xie Wuregret handed over the long knife to the eunuch Ma Yongquan with a respectful face, in fact, this knife also needs a long handle of jujube wood or peachwood, so that the dancing of both hands can give full play to the power of chopping, Li Er is not an expert in using knives, he is used to using a long lance, but martial arts are all connected, Li Shimin, who has practiced martial arts since childhood, took the long knife and danced a knife flower on his chest, and accidentally cut off his beard and rubbed it a lot, in order not to admit it, he also pretended to turn a blind eye and continued to pick, Yang Lin was worried that Li Er's holy face would be damaged if he continued like this, Hurriedly asked Xie Wuregret and others to bring the weapon rack.

"Bang."

With a crisp loud sound, a row of severed swords and iron filings flew on the weapon rack, and under Li Er's strength, those original Tang Army-style swords were cut like pieces of paper, and the scene was very terrifying.

"The first divine soldier, the first divine soldier is also ・・・・・・"

In the craftsman workshop, the exclamations came and went, Li Er only felt that he was full of strength, and he just cut a bunch of weapons into pieces in one breath before stopping, it was really a treasure knife in his hand, I have it in the world!

"I have become the number one divine soldier in the world, and no one can destroy it." Li Er's long knife pointed at the sky, regardless of the beard of a place, and got the deadly way.

Yang Lin took Li Li's little hand and hid far away, in the corner, Gu Yue Daowen, who didn't look at it, carefully used iron wire to connect the new plate steel with small holes on the back, and after a while, a simple plate steel vest without sleeves was completed by him, no wonder he was so skilled, these new plate steel are cast from the mold of the craftsman to make the Mingguang armor, as long as it is fired, it is not difficult to form armor.

"Your Majesty, may you break this armor?"

Gu Yue Daowen likes to hit others when they have sè, especially when this person is Li Er, he is holding a vest plate armor and hanging it on the weapon rack slowly, that unhurried bearing seems to be very confident, in fact, he is not confident in plate steel, he is convinced of Yang Lin's words, what this guy says out of his mouth is scientific truth, the truth of the world, you can't believe it.

"Look at me breaking it."

Li Er shouted, the long knife slashed towards the armor, the jingle bell sounded, and the sparks shot out, and the fragmented situation that everyone thought would appear did not appear, and with Li Er's strength, he swung the high-carbon steel broadsword and slashed over, but it only left a shallow scratch on the surface of the plate steel.

"Boundary."

Xie Wuhui looked at the plate armor carefully, speechless with excitement, he never imagined that the metal produced after the smelting of this pile of stones identified as waste ore can actually increase the toughness of steel by multiples, as long as a little bit can make a large boiler of molten iron produce qualitative changes, which is completely incomprehensible to the Tang people who do not understand metal synthesis technology, in fact, titanium is generally used in aerospace science and technology in later generations, and titanium alloy is the main material for satellites, which is almost the highest strength metal that can be produced in modern times. With the existing means of the Tang Dynasty, if you make a titanium-magnesium alloy sword or plate armor, it can be called an eternal divine soldier and an eternal treasure armor.

Gu Yue Dao shook his legs, but Li Er didn't bother to look at his **, took the plate armor from Xie Wuregret's hand, and wiped it repeatedly, it was obviously the appearance of true love, if the eldest grandson saw such a scene, I am afraid he would be jealous.

"Congratulations, congratulations."

Under the leadership of Xie Wuregret, the craftsman supervisor and the craftsmen of all sizes bowed to Li Er for the first time in a majestic manner, needless to say, the credit for casting the sword and armor belongs to the craftsman supervisor, Li Er, whose mind has drifted away, seems to remember the scenes on the battlefield back then, if he had such a sword and armor at that time, those many brothers who were born and died together may not have left him early.

"Let's congratulate Datang together."

Li Er raised his sword in his left hand and his armor in his right hand, and there was a 360-degree slow rotation around the field in the field, as if he accepted everyone's blessings in place of this divine armor, and the yang forest who bent over and kowtowed secretly shattered the famous sentence 'The ancient emperors are all actors, and if they are not actors, they are faint kings'.

Gu Yue Daowen didn't kneel, he was much more courageous than Yang Lin, looking at him, he should be proud of his merits, pride is the same as labor, and it will be invalid if it expires.

"Father, you should be able to perceive this matter, the significance of rare mineral metals for steel itself, my Tang Dynasty is full of treasures, as long as my father orders all provinces to collect some strange minerals and rare earths, maybe the sword can be sharper, the armor can be more tenacious, to build an indestructible strong army, these swords and armor must be constantly upgraded."

Yang Lin resolved the embarrassment of the two pretending to be forced in a timely manner, Gu Yue Daowen's loyalty to Li Er is in his heart, on the surface, he seems to be a heavenly boss, my second child's style, you are the son of heaven! At most, I am tied for second place.

"You are the greatest treasure that God has given me, and I will specially allocate a group of people who can be sent out to the craftsmen as supervisors, and they will be responsible for collecting these rare mines for the craftsmen in the future, so that they can forge better swords and armor." Li Er handed the big knife and armor to Ma Yongquan, and helped Yang Lin up, this meaty compliment was naturally made for Gu Yue Daowen to see, and what the two of them like to see most now is that each other is suffocating.

"It's not just swords that can strengthen the army, these are all small paths, and when the new invention of my master and apprentice comes out, your majesty will open your eyes and see it." Gu Yue Daowen shook off a cruel word, it seems that he plans to squeeze something from Yang Lin tonight.

"I'll see. Hahahaha・・・・・・" Li Er laughed and left, not forgetting to take away the half-finished broadsword and armor.

Yang Lin didn't understand why one obviously needed the other party's help to make things, and the other obviously wanted to make things for the other party, but why he had to show that he didn't have a harmonious relationship in front of everyone.

"Apprentice, you can teach the teacher again!"

Yang Lin's ears were about to cocoon when he heard this line, and the curiosity of scientific people about unknown things Yang Lin understands, but your baby also has to know that the rice can only be eaten one bite at a time! Yang Lin has already handed over a set of gears to drive the pulley, and then drive the water wheel to propel the boat on the water to Gu Yue Daowen, this baby still wants to get involved in the casting plan of the shotgun, he really doesn't know that Yang Lin is actually a giant lazy, can not move, will never move his feet, so he drew a lot of drawings to Gu Yue Daowen and then completely let go, before leaving, he also said that three days later, look at the spot.
