King Fu made up his mind and began to plan how to kill King Yu. However, it always takes some time to plan for such a big event.

And Liu Chengzhi's vision is too old. Less than two months later, in May, the Ministry of Industry had not completed the transformation of the blast smelting furnace, and a large amount of coal had been transferred to Huaiyuan County through the transportation rail line.

Among them, there is a cart of charcoal, which is not the jet-black and shiny color of ordinary coal, but is gray-black in color, with a rough surface and much lighter weight. The charcoal burners who came with them called this kind of thing coke.

After the deliberations that shocked Liu Cheng's heart that day, the emperor handed over the matter of mining coal and removing impurities from coal to the general as a prisoner. Liu Chengzhi and Fuwang didn't even know the progress of the matter, so they got the news from the Ministry of Industry that coal and coke had been transported to the smelting workshop's storage yard.

When King Fu got the news, he sat in the household department and his exclusive office room, thinking deeply with deep eyes, which step did he delay time?

Where is it easy to assassinate the prince, or the prince who is just popular? That requires careful planning and timing.

His movements are already fast, and next month will be the birthday of Prince Lao Chong. There are many people attending the birthday banquet, and the scene must be lively, and it is best to start at that time. The personnel and various steps have been arranged, just waiting for the time for the birthday banquet to arrive.

However, when did the efficiency of the prison become so fast? It only took more than a month for what Liu Chengzhi was worried about to happen.

King Fu secretly sighed that God was unfair, but he could only continue to act according to the plan, and at the birthday banquet of Prince Lao Chong next month, he attacked King Yu. Otherwise, it would not be easy to find such a lively occasion with Jinrong in attendance.

Although the Ministry of Industry has stepped up the production of blowers for iron-smelting furnaces, the short period of two months is really short.

By the time the coke arrived, there was still only one blast smelting furnace in the world. This is the only furnace that can test the effect of coke.

At the beginning, the veteran of the smelting workshop replaced part of the charcoal with coke, and after the smelting effect was stable, the amount of coke was gradually increased until all the charcoal in the smelting furnace was replaced with coke.

Half a month later, a batch of iron made from coke as fuel was quietly sent to the imperial court's weapons factory.

After all this batch of iron was made into weapons, the emperor left the palace again. This time, I took several generals led by An Guogong and Shangshu of the Ministry of War to the weapons factory to inspect the quality of new materials and weapons.

The emperor and the relevant generals and officials of the military department did not publicize the results of the inspection of the weapons, and even some ministers in the court who had nothing to do with it did not know that the weapons factory had created a batch of weapons of different materials.

However, in the records of the Ministry of Industry, there is an additional smelting product called steel. Take the meaning of its incomparably hard.

And secretly, a kind of ecstasy permeated some military generals and officials in charge of armaments.

At the same time as this undercurrent is surging, the DPRK is building weapons out of steel, and plans to gradually replace the weapons in the hands of the guards stationed at the border.

This result made King Fu and Liu Chengzhi breathe a sigh of relief. At the very least, the success of steel smelting is due to the joint efforts of the supervisor and the smelting workshop, and Jinrong and Ye Xinyan did not participate in it. At least that's what people who don't know why.

June 18 is the birthday banquet of Prince Lao Chong, and King Fu consciously has made preparations, and he has laid the groundwork before and after, just waiting for the birthday banquet to come and implement it as planned.

However, things often do not depend on human will. There were still three days before the old prince's birthday banquet, and the sun had not yet set, a middle-aged man dressed as a scribe came to Liu Yu's residence and reported that Liu Yu had been an old friend for many years, and he had not seen each other for a long time, so he came to visit.

At nightfall, Liu Yu and the scribe were full of wine and said goodbye outside Liu's mansion. Liu Yu also arranged his own carriage very intimately, helped him into the carriage and sent him away.

As soon as the dynasty dispersed on the morning of the second day, a family member from King Fu's Mansion came to report that a pregnant concubine of King Fu had fetal gas, although it was diagnosed and treated, but the anxious mood was still unstable. Therefore, Princess Fu asked King Fu to go back to appease the concubine.

It is a matter of the prince's heir, and it cannot be delayed. King Fu greeted the new Hubu Shangshu and returned to his palace.

Entering the palace, King Fu did not enter the back house, but went to the living room in the front yard. In the living room, Liu Yu was anxiously waiting for him.

Liu Yu didn't say much to King Fu, and after greeting him with a simple salute, he followed King Fu's steps step by step, and reported while walking into the house: "Yesterday evening, a scribe who claimed to be Chen Xie came to find his subordinates. The scribe opened his mouth and asked, "Are we going to do anything at Prince Lao Chong's birthday banquet?" ”

King Fu had already walked to the chair at the top, and just wanted to sit down, when he heard Liu Yu's words, he couldn't help but be surprised: "Who is he?" There should be no omissions in the planning and arrangement of our matter, how would he know? ”

"Chen Xie said that he was the one who did things for the prince." Liu Yu said.

King Fu was stunned at first, and then frowned: "Prince? What does he want to do? ”

Liu Yu's face was not good-looking. They did this very secretly, using extremely reliable people, and there was no possibility of leaking information at all.

But what's going on with this Chen Xie? Just as they were about to make a move, he came to him. And people also know when and who they are going to do, which is very frightening to hear.

"He spoke for the crown prince. The crown prince said that it was useless for His Highness to do this, and he wanted to meet with His Highness to discuss cooperation. ”

King Fu snorted coldly: "There is not enough success, but there are more failures." From the time I entered the court, I saw too much of his extravagance and inaction. Talk to him about things? In addition to not getting the slightest benefit, he will be implicated to death. ”

Liu Yu sighed and persuaded, "Your Highness, let's go and see the crown prince." In any case, the things at the birthday banquet of the old Chongxin king cannot be done. Although the medicine did not attack on the spot, some people already knew about this plan, and if something happened, I was afraid that it would really be able to find out to us. ”

On the second day, the prince just entered the palace to greet the queen.

When he got out of the palace, he didn't do anything to hide it, first went to the cabinet for a turn, and talked nonsense with a few nervous looks. Then I came out of the cabinet department, and as soon as I turned the corner, I went to the household department.

I greeted people all the way, saying that he had been in and out of the household for many years, and he had some feelings, so he stopped by to have a look.

He walked all the way and waved his hands, let everyone be exempt from courtesy, and walked around the office of the current head of the household department, and went straight to the door of King Fu's room.

King Fu was restlessly waiting for him. From the open door, the prince could be seen walking very leisurely, with two little servants, coming to him.

When King Fu saw the prince for the first time, he quickly got up and greeted the prince at the door.

Before he could speak, the prince said with a smile: "The seventh brother has always been good, how is the errand of this household?" This room is very comfortable, right? This is the place where your second brother and I have carefully cleaned up. ”

King Fu was unhappy in his heart, but his complexion remained unchanged. I saluted the prince first and let him in. The officials who were in and out of the patio outside peeked and watched the two enter the house before they dispersed. I want to talk about "Women's Beauty" with more like-minded people, pay attention to "excellent reading literature" on WeChat, talk about life, and find confidants~
