Yichun Palace, also called Qin Palace.

Located in the Yichun Garden, the royal garden in the southeast of Xianyang City, the trees and flowers are luxuriant, although it is the winter season, you can also see green bamboo and yellow flowers with landscapes.

It is the residence of Hu Hai, the eighteenth son of the first emperor Yingzheng, and Hu Hai at this time sits in the cuizhu courtyard, holding a pen and bowing his head to write.

"The writing skills of the eighteenth prince are getting stronger and stronger," one of the people sitting on the other side suddenly spoke, and his voice was tinged with a hint of gloom.

Hu Hai raised his eyes and saw that his face was handsome, the bridge of his nose was high, and there were seven points between his eyes and eyebrows, but a pair of red eyes looked a little weird.

Hu Hai stopped writing and said: "That's also what the master taught." ”

"It is the duty of the old slave to let the old slave teach the eighteenth son to write."

When it came to Yingzheng, the master and servant couldn't help but show a different color, seeing that Zhao Gao's words were full of resentment, Hu Hai glanced at each other, and clearly saw that there was something hidden in their eyes.

Hu Hai suddenly got up and asked, "Master, do you know what your father has been doing recently, Hai'er hasn't seen her father come to Yichun Garden for a long time." ”

Zhao Gao twisted his eyebrows and sighed: "In recent days, Your Majesty has been served by Meng Shangqing, and the old slave knows very little. ”

Hu Hai picked up the scissors and trimmed the branches and leaves in the basin, and whispered: "Yes, Hai remembers that the master secretly supported an organization......

Zhao Gao looked at Hu Hai's back, a hint of ghost flashed on his face, and said, "Is the eighteenth prince ready to settle for the status quo?" ”

Hu Hai's strange red pupils shrank, turned around and said with a smile: "Everyone in the world knows that the elder is not the younger, not to mention that no one inside and outside Xianyang knows that the eighteenth son likes to have fun, so how can he be satisfied with the status quo." ”

Zhao Gao suddenly arched his hand and said: "Your Majesty, because of the Immortal Monarch, the root of the disease has recovered most of the time, what will happen in the future...... According to the old slave, I'm afraid it's a little uncertain. ”

Hu Hai changed his words and said: "The eldest brother was sent to supervise the Meng Tianjun because of his father's confrontation, if he has a friendship with the Meng family because of this, ......"

The corners of Zhao Gao's mouth suddenly twitched, and he squinted and smiled: "The eighteenth son doesn't need to worry, the Meng family has been loyal for generations, and he is only loyal to His Majesty." ”

Hu Hai shook his head and said, "Not necessarily, this time the father and emperor have promised Hai to go with him, but in the end he left me in Xianyang." ”

Zhao Gao's expression changed, and a trace of ripples appeared in his heart, if the eldest prince Fusu was recalled, how could Meng Yi's revenge be avenged.

But he has taught the eighteenth son Hu Hai for many years, and his ability is indeed far worse than that of Fusu, so he came up with a plan and said with a smile: "Your Majesty's heirs are thirty-two, but you only love the eighteenth son, if the son can surpass the eldest son, there may not be no hope." ”

Hu Hai shook his head helplessly, and said: "The heart of the father is as elusive as the stars in the sky, and if he wants to surpass the eldest brother with his ability, it is not a fool's dream." ”

Zhao Gao's expression flowed, and he suddenly said: "As far as the empire is concerned, if you want to dictate yourself, blood relatives are the biggest barrier. ”

Hu Hai's expression changed, and he couldn't help but feel a wave in his heart, and said with some doubts: "With the temperament of the eldest brother, if it really comes to that day, Hai also believes that the eldest brother will not ignore the kindness of the bloodline." ”

Zhao Gao sneered at first, then sighed and said: "According to the report of the old slave's subordinates, His Majesty's will has been out of Xianyang City three days ago through the hands of Shangqing. ”

Hu Hai was shocked in his heart, Xianyang was full of the shadow of his father, how did the master secretly cultivate power was not detected by his father.

Hu Hai shook his head again and denied: "Impossible, with the means of my father, it is impossible not to detect it, but even so, why did my father let it ......?"

Seeing Hu Hai's face change, Zhao Gao's eyes flashed, and he said with a smile: "Giggles, the eighteenth prince doesn't need to worry about it, the forces of the rivers and lakes can't enter the eyes of His Majesty and his old man." ”

Hu Hai was stunned when he heard this, the forces of the rivers and lakes?

Seeing that Hu Hai's heart was shaken, Zhao Gao smiled at the corner of his mouth, his body moved, and he suddenly lowered his head and said: "The Immortal Monarch Marquis is now deeply appreciated by His Majesty, if the prince can get his help, he may not be able to ......."

Hu Hai's heart was shocked, and the deeply buried seed in his heart was like nectar, sprouting and growing with a hint of hope.

……

"I've been feeling weird lately, isn't it carbon monoxide poisoning?" Li Yu couldn't help but shake his head self-deprecatingly.

When Feng Yansheng, the palace eunuch beside him, heard this, he asked with some confusion: "Lord Junhou, what is carbon monoxide?" ”

It's no wonder that Feng Yansheng has become a curious baby, but in recent days, he has followed Li Yu to supervise the construction of a new foundry, and the knowledge that Li Yu casually said made Feng Yansheng, who was born as a craftsman, ask whenever he has doubts.

Why is sea salt added to the quenching stage in the foundry line?

Why does the heating furnace need to add a blow outlet to place the water wheel?

Why was this foundry built near a river?

And Li Yu's way to answer these questions is to directly take a group of blacksmith supervisors around the built foundry and start directly.

In the words of Li Yu's five-character mantra, it is: practice brings true knowledge.

For the forty or fifty-year-old government supervisor next to him, Li Yu was quite helpless, but he also enjoyed it, pointing to the heating stove and smiling: "Do you see the smoke and dust on it, when the charcoal burns, it does not completely turn into an open flame to calcinate the gold and stone, and a part of the charcoal directly becomes a gas because of heating, and this part of the gas that passes is carbon monoxide." ”

Supervisor Feng Yansheng looked confused, Li Yu couldn't help but pick up a piece of charcoal next to him and said: "There is a component called oxygen in the air we breathe, which is why you usually add a bellows to the temperature of the charcoal fire, this oxygen makes the charcoal burn, and then the two produce some kind of unnatural blend......

Li Yu shook his head suddenly, paused and said: "Yes, Ben Hou wasted his tongue, Lord Feng only needs to know, this thing is just like your fart, sucking too much can easily make people dizzy, and even become idiots or die." ”

Seeing that Li Yu didn't want to say anything more, everyone present nodded regardless of whether they understood it or not.

Feng Yansheng said: "Lord Junhou, the heating furnace uses a waterwheel to continuously heat, and the bellows are heated by manpower according to the situation, and the addition of charcoal after grinding into powder can indeed melt the gold and stone called iron, and after the sea salt melts the water, it is indeed as you said, it is easier to cool, and it is less easy to break, and the hardness is also higher. ”

Li Yu smiled and said nothing, not to mention the three-percent combat power, if he could form forged steel in the future, in the face of hand-to-hand combat with foreign enemies at this time, it was simply to cut the opposite weapon as a vegetable, of course, it was no problem to chop people as vegetables.

Immediately went straight to the point: "Have the twenty sets of armor and weapons requested by Ben Hou been made?" ”

Feng Yansheng suddenly hesitated when he heard this: "Lord Junhou, the imperial law says that you can't hold troops and weapons for personal gain, if Your Majesty blames it, the lower officials can't hold back." ”

Li Yu gently patted Feng Yansheng's shoulder and said with a smile: "Lord Feng, don't worry, these twenty sets of armor are for Your Majesty, you just wait for the reward." ”

Feng Yansheng was overjoyed when he heard this, his expression moved, and he bowed down and said, "Xie Xianjun Marquis promoted." ”
