The fastest update of the latest chapter of the Nine Heavens Refining Divine Formula!

Wang Xinghe, the ancestor of the Wang family, is old, black, thin and short, but his spirit is very strong, and he always has a faint smile in his eyes.

He sat on the main seat of the dining table with a dragon's head on crutches, and did not eat himself, but just smiled and watched the juniors eat.

From time to time, he also stretched out his finger to point to the dishes on the table without moving chopsticks, and said to Ye Changsheng: "Boy, try that fried sea sausage, the old man's favorite before, help the old man eat more." ”

Okay, Ye Changsheng nodded, no, he put down a pair of chopsticks, it was really delicious, and it was very strong.

He pinched several chopsticks in a row, until Wang Lao ordered the next dish for him again.

After three rounds of wine and five flavors of food, Wang Lao asked about the recent situation of Jiantang.

The five juniors of the Wang family who accompanied them also put down their chopsticks one after another, looked at Ye Changsheng curiously, and listened very carefully.

They were able to see Ye Changsheng differently, not because of how famous Ye Changsheng had been in the past two years and how many people touted his genius, but simply because the old ancestor looked at Ye Changsheng differently.

Ye Changsheng is the only one who can be called a year-old friend by the ancestors, which has caused a lot of shock within the Wang family, and unreliable people still guess that Ye Changsheng and the old ancestor are related by blood.

Of course, that is impossible, the Wang family also has strong connections, a perfect intelligence system, and can also use the power of the state, so they quickly investigated Ye Changsheng's background clearly.

Ye Changsheng turned out to be a descendant of the Nanfeng lineage of the Ye family in Maple City, so everything was clear.

Yes, the Wang family has some relationship with Nanfeng Yimai, to be precise, they owe Nanfeng Yimai a favor.

At the dining table, the ancestor listened to Ye Changsheng's harvest and praised: "Okay, good, the meaning of our craftsmen's existence is to continuously promote the development of skills, never end, and never slack off." Back then, our Wang family was once complacent, proud and complacent, but thanks to the awakening of a swordsmith, a catastrophe was avoided. ”

A swordsmith?

Ye Changsheng was surprised.

Wang Lao's eyes were full of reminiscence, and he said slowly: "It was sixty years ago, the old man designed the most powerful warship, after ten years of testing, it was decided to officially install the fox and replace it with all the old ships⊥ when the shipyard was rushing to work, a swordsmith who traveled to the seashore, accidentally found that the metal rivets that fixed the deck and watchtower on the warship had a fatal hidden danger. ”

Ye Changsheng couldn't help but ask, "What fatal hidden danger?"

He has inspected the ships built by the Wang family, and he has also specially taken out a few rivets for testing, and he is very particular about both toughness and firmness.

As for the rust, corrosion, and even the erosion of some aquatic weeds and parasites that ordinary ships will encounter, they are basically taken into account, and even the sound waves of water waves and the resonance of the hull are also taken into account.

Ye Changsheng really couldn't think of how a thousand-year-old shipbuilding family could make a fatal mistake?

Wang Lao looked at a junior of the Wang family: "Yun Jian, come on." ”

Wang Yunjian nodded hurriedly and said to Ye Changsheng: "Ferromagnetic!"

Ferromagnetic?

Metal rivets are so magnetic that they interfere with the accuracy of the compass?

This can't be.

With a move in his heart, Ye Changsheng said, "Could it be a thunderbolt?"

A hint of approval flashed in Wang Yunjian's eyes, and he nodded: "It is the lightning guide, because the magnetic field of the rivet has a special gravitational force on thunder and lightning, which can pull the falling thunder and lightning over." Just imagine, if such a sea ship were sailing in a storm, I am afraid that before a single enemy has encountered it, it will be completely wiped out under the natural disaster first!"

Wang Lao continued: "At first, the old man didn't believe it at all, after all, the newly shaped sea ship and even every component have undergone ten years of testing, and there has never been a lightning strike. However, the swordsmith took the people of the Wang family and did some experiments in person, and the result was that the old man was wrong!"

Ye Changsheng said slowly: "Is it because there is a problem with the metal ingredients, so the magnetic field of the rivets cast by the fusion is quietly increasing with the passage of time, and finally reaches the strength of lightning traction?"

Wang Lao nodded and said: "That's true, after some tests by the old man himself, he also deduced the law of change of the metal magnetic field, which is exactly the same as that of the swordsmith's calculations." ”

Ye Changsheng was amazed, if it was him, he was afraid that he would not be so careful, and he would notice the change in the metal magnetic field.

Even if they do, they may not be able to deduce the connection between the performance and the thunder and lightning.

In fact, he doesn't have the slightest clue right now.

Elder Wang looked at Ye Changsheng and said with a smile: "Boy, are you also curious now, how did that swordsmith do it?"

Ye Changsheng nodded humbly, if he didn't know, he didn't know, it was true that he was a sword casting master, but he was not omniscient, in fact, he would not be omniscient in his life.

Wang Lao took out a yellowed piece of parchment from his arms and handed it to Ye Changsheng.

This is a secret that will not be passed on, do I think it is appropriate?

Looking at Elder Wang's encouraging eyes, Ye Changsheng nodded, took the parchment and slowly opened it.

Before he had time to look at the scribbled formulas and data above, Ye Changsheng was attracted by the signature under the parchment.

Nan Feng, Ye Wenzhang!

Ye Changsheng's hands trembled a little, his eyes were red, he silently put away the parchment and bowed deeply to Wang Lao.

Wang Lao accepted this worship calmly and looked at Ye Changsheng: "Wen Zhang, it's your uncle and grandfather, right?"

Ye Changsheng nodded silently, his tracing of Nanfeng's lineage was only to his grandfather's "Wen" generation, so he knew the names of his grandfather's three brothers.

Twenty years ago, on the night of the collapse of Nanfeng's lineage, the only surviving uncle and grandfather in "Nanfeng Sanwen" committed suicide by poisoning that night.

Wang Lao sighed: "When I heard the news of Wen Zhang's death, the old man was endlessly sentimental, but he was helpless, how could our Wang family not have such a tragedy, although it was not the emperor's family, but it was also involuntarily." ”

Changsheng lowered his head: "The younger generation is my uncle and grandfather, thank you to the old ancestor!"

Wang Lao nodded, stood up and said, "Boy, stay in the city for a few days, take a look around, don't take the conflict between you and the Xianyuan Hu family to heart." ”

As he spoke, Wang Lao turned around and walked out, and immediately two juniors stepped forward quickly, supported the old ancestor, and walked out.

Wang Yunjian also stood up and said politely: "Ye Gongzi, the residence has been arranged, you can rest first." ”

Ye Changsheng nodded, followed Wang Wenjian out of the restaurant, and entered an elegant courtyard several times.

Several slaves and maids had been waiting on the side for a long time, and after seeing Ye Changsheng, they were busy.

In the next few days, Ye Changsheng, accompanied by Wang Yunjian, visited the Wang family's shipyard and foundry, and gained a lot.

Seven days later, the ocean-going ship was finally ready, and it was time for Ye Changsheng to leave.

On the pier, a large ship is ready to set sail.

Wang Wenjian came in a hurry and handed a belt to Ye Changsheng: "Ye Gongzi, the belt is what the ancestor handed over to you, and his old man is waiting for you to come back safely!"
