The matter of forging swords was in full swing, Ou Yezi finally couldn't bear the uneasiness in his heart, and took his wife and cadres to Yefu Mountain where swords were cast, where the minerals were extremely rich, and after several generations of swordssmiths polished, it has become an excellent place for swords.

Lu Yin hired a large number of workers, and after arriving, he began to repair some houses that provided food and shelter, and began to dig mountain walls, divert water, and go deep into the mountains to find some ore.

After Ou Yezi arrived with his family, he began to help, and his wife, Lu Ke, took a three-year-old cadre.

Lu Yin took some people into the mountains to look for ore, and went for a month before he came back, and when he came back, he found that Ou Yezi had already taken people with him, and had already placed the pool, furnace, and water flow for casting swords at the foot of Yefu Mountain.

In desperation, Lu Yin had no choice but to agree, Ou Yezi was here.

In order to forge a peerless sword, the materials used must be turned over and cast, and all the magazines must be eliminated, which takes a long time, and most of the disciples, after finishing their work, go back one after another, because at this time, all countries are constantly rubbing, and the number of weapons needed is extremely huge, and many people are unwilling to stay and help Lu Yin cast the sword.

Only Ou Yezi, he knows very well that his master, this time, the sword he cast, is the best one in his life, and the work of forging the sword is carried out by Lu Yin himself, while Ou Yezi is just helping to add water, watch the stove, and cook.

The sound of tinkling and ding, every day, is echoing in this mountain, gradually, it has been a year, King Yue has sent people to urge several times, but Lu Yin, on the grounds that he wants to build the best sword, let these urging people go back.

The forging of the sword was in difficulty, only the four of them stayed, and Ou Yezi had to return to the city to replenish the materials in person from time to time, and then ask someone to transport them.

Looking at his master, getting thinner and thinner, Ou Yezi hoped that he could help a hand, and he continued to study the ore, because the current swords are all made of bronze, at this time, Ou Yezi came up with an idea, why not use iron to make weapons.

After such an idea was born, Ou Yezi and his master discussed it all night, and for several days, the two of them continued to cast things.

Such an idea, Ou Yezi, also before, when casting iron, discovered, he felt that iron can be sharper than bronze, and the hardness is better than bronze, and it is not easy to break.

After nearly half a year of experiments, Lu Yin was defeated, and he was very pleased that the apprentices he had taught had completely surpassed himself, whether it was thinking or casting technology.

"Yezi, your idea is correct, I'm afraid you are ahead of this era, after all, one day, bronze will withdraw from the stage of war, and iron weapons will become the main means of casting."

Leaving only these words, Lu Yin took dry food, and entered the mountain, he was determined to find a more pure cold iron, that kind of iron, buried deeper, rare, but before, Lu Yin had seen it.

It took nearly half a month for Lu Yin to finally come back with the ore he found, this kind of iron, than ordinary iron, has a better gloss, and is harder, it is very difficult to smelt, and it is another thing to kick out the impurities.

3 years have passed, and what makes Ou Yezi the happiest is that he has a daughter, named Mo Xie, which is the name given by his father-in-law, Lu Yin, which means to be upright.

At this time, the cadre was a little bigger, and what surprised Lu Yin was that this child, who was almost 8 years old, was no worse than Ou Yezi in his talent for striking iron, and Ou Yezi was also aware of this.

Some small iron tools, after Ou Yezi taught the cadres for a while, he could use a small hammer independently and polish it by himself, and he didn't lose to Ou Yezi, all of this seemed to be innate.

In his spare time, Lu Yin patiently and meticulously began to teach the future, he and Ou Yezi are geniuses of different categories, Ou Yezi has a slender heart, is good at thinking, and can always develop some simpler and better ways to join the casting process.

The cadre is different, he belongs to the kind of blacksmith who holds the hammer as if he has a god in his body, and the technique of building is just right, and many steps that make some blacksmiths have a headache, but he can do it in one go.

By the sixth year, Lu Yin had completed all the steps, a peerless sword, cast, an old man, a young and a young, three blacksmiths, at this moment, showed a smile.

And this sword, named Killing, as soon as the sword came out, the cold light overflowed, and where the sword edge passed, it split stones and broken wood, whether it was the sharpness or the sharpness that the sword originally exuded, it had reached its peak.

"Yezi, cadre, you two come here."

Lu Yin called the two disciples to him.

"Yezi, in the future, you have to be a good student instead of a teacher, teach your junior brother, cadre, in the future, everything, listen to your senior brother Yezi, you two brothers, after all, one day, will become a world-famous swordsmith, but remember, swordsman, straight heart, this, don't forget."

After explaining all this, Lu Yin took them down the mountain together.

Originally, Lu Yin planned to go to the sword alone, but under the strong persuasion of Ou Yezi and the cadre, he agreed to follow the two together, and the three of them arrived at the royal capital a few days later.

At this time, Yue Wang Yunchang was terminally ill and a little confused, and his son, Gou Jian, was also ready to succeed to the throne at any time, but in the city, there was a breath of uneasiness, and some forces in the secret did not want Gou Jian to succeed to the throne, because the people of the world only had two words for Gou Jian, poor and weak.

Such a monarch, in such a troubled era, will definitely not be able to do great things, not only the State of Wu, but even the State of Chu, who is clearly on the side of the Yue State, but secretly, the matter of wanting to annex the Yue State has long been known to the world.

The killing carried by Lu Yin, the last process, was not completed, and it still needed to be put into the furnace, smelted the surface, and engraved with an inscription belonging to King Yunchang of Yue.

In this final process, a furnace was set up in front of the ministers, and preparations were made to perform the sacrifice at the same time as the sword was completed.

At this time, Lu Yin's face was even worse, Ou Yezi didn't know, his master, what was wrong, although the cadre was young, he could also see that his master was very unhappy, and he stared at it and asked.

"Cadre, don't ask again, the master looks annoyed, we just need to follow the master silently, what is the reason, he will naturally tell us, wait for the matter to pass."

On the eve of the start of the last process of sword casting, the young cadre was full of anxiety in his heart, and so was Ou Yezi.

At noon the next day, in front of the Minister of Civil and Military Affairs, the dying Yue Wang Yunchang was pushed out, and he looked very happy.

Lu Yin took two disciples, in the middle of the furnace, began the last way of casting the sword, the work of engrave the inscription, a whole morning, finally completed, this peerless sword, killing.

The ministers cheered happily, and the sick and weak Yue Wang Yunchang came over, and after picking up the sword, there were soldiers immediately, bringing out some unkempt prisoners, and at this time, Lu Yin's face was already a dead ash.

King Yue, who held the sword in his hand, effortlessly, used this killing to cut off the heads of these prisoners, and after the successful sword test, the ministers were full of beautiful hopes for the power of this sword and the national fortune of their own country.

"This killing will definitely help the king, help us cross the country, kill the Quartet, come here, set up a banquet with wine."

Then, just as Lu Yin was about to leave, King Yue stopped him.

"Lu Yin, this king asks you, in the future, who will you forge a sword for?"

"Back to the king, this is the last sword that Xiaomin has built in his life."

"Okay, good, it's really a peerless sword, but this king doesn't believe it, so, Lu Yin, you jump into this furnace to ensure that this king's unparalleled sword in the world will not be replaced."

As soon as these words came out, the ministers were surprised, but no one dared to speak out, the young cadre was excited, and immediately around, there were soldiers coming over and suppressing the three of them, Ou Yezi seemed to finally understand that a few years ago, Lu Yin and himself said, rabbit dead dog cooking, what is it.

Ou Yezi and the cadres kept shouting, and Lu Yin took them to the stove that was still burning.

"The king, since it is the king's order, Lu Yin should enter this furnace, and like this sword, pray that the king can prosper the country."

Lu Yin didn't flinch at all, he pushed away the soldiers who grabbed him, and stepped on the high platform step by step, Ou Yezi and the cadres all cried, crying and shouting, and Lu Yin just turned around, smiled, and looked at them.

"Yezi, cadre, never forget, temper these four words."

After saying this, Lu Yin jumped into the furnace, Ou Yezi roared, broke free from the soldiers who pressed him, and ran to the furnace, and the cadres behind him also followed.

Suddenly, there was a loud noise, and the soldiers around him drew their weapons, and Ou Yezi suddenly grabbed the young cadre.

King Yue laughed wildly, he had completely fallen into madness, and then kept shouting that he was going to kill the Quartet, so he spat blood and fell to the ground.

"The king is dead, the king is dead........"

The ministers were all in chaos, and for a while, the scene was very chaotic, Ou Yezi quietly half-squatted on the ground, holding the cadre who had been crying and hissing exhausted, and quietly looked at the flames that were still burning in the furnace.

Gou Jian, officially succeeded to the throne after Yun Chang's death, and at this time, Wu Guo began to move at the border, Ou Yezi returned to Yecheng with his cadres, and continued to start the work of striking iron.
