At noon, Xiao Ran called a nearby hotel and asked them to deliver meals to the hospital.

Didn't go back to the villa to eat.

The little princess was surprised to see the different dishes.

"Seven rice rice~"

"Aunt, do you want to get up or eat in bed?"

Empress Changsun's IV drip was temporarily finished.

"Just get up!" Empress Changsun lifted the quilt.

Li Lizhi hurriedly supported Empress Zhangsun, "Mother, slow down."

"It's fine."

The two little princesses looked at the food on the table and were very greedy.

But it won't move first.

It's good that you won't reach out to take it.

It is normal for children of this age to scratch around before eating.

"Aniang Qifanfan~"

"Well, good!" Empress Zhangsun sat down. "Xiao Ran, Li Zhi, when will you return? His Majesty will be worried if there's no news for too long."

Li Lizhi looked at Xiao Ran and asked Xiao Ran to make the decision.

"Aunt, wait until Sixth Sister wakes up and she's watching over us. We'll go back and talk to Uncle-in-law. Everything's fine."

Xiao Ran could only ask Li Shimin, the old man, to wait a little longer.

"Yeah, that's fine!"

Princess Yuzhang is now asleep, worried about Empress Changsun being here alone.

We can't go and wake Princess Yuzhang up either, she has been up all night.

Since Empress Changsun is here, Princess Yuzhang's schedule will have to be adjusted.

Some time should be set aside to take care of Empress Changsun.

It is not possible to keep Li Lizhi because she doesn't know anything about the hospital.

Xiao Ran could only accompany him.

After dinner, the little princess began to doze off.

Lying in Xiao Ran's arms, "Little Nangjun~Flying home~Want to slumber~"

The little princess was very sleepy.

"Mingda, we can sleep here too. Can we sleep next to you?" Xiao Ran pointed to the bed next to the hospital bed.

"Yeah~"

Soon the two little princesses fell asleep in bed.

The schedule is very punctual.

I feel sleepy when it's time.

"Changle, you should go to sleep too! Sixth sister should be able to sleep over there."

Xiao Ran lowered his voice, afraid of disturbing the little princess.

Li Lizhi shook her head, "Young Master, I'm not sleepy."

Li Lizhi felt that it would be inappropriate for her to go to sleep and leave Xiao Ran behind.

The two of them could only sit and wait in the ward.

......

"Your Majesty, everything has been handled according to your instructions." Zhang Ananda found Li Shimin.

Li Shimin looked at the coal and said, "This one doesn't look much different from the previous one!"

"It does look like there's not much difference. They're both the same black." Zhang Ananda smiled.

Through the impact of water flow, raw coal with different components and specific gravities is separated into different grades, dust and waste rock are removed, and the ash and sulfur powder content is reduced. This is called coal washing.

Coal washing is an indispensable link in coal processing. The coal after washing is called clean coal. In addition to achieving the purpose of environmental protection, coal washing can also improve the utilization rate of coal, etc.

"If you can't tell, then try burning it. Get a stove and put the coal in to burn it." Li Shimin ordered.

"Yes, Your Majesty, I will take it out and burn it right away."

"No need, just burn it here." Li Shimin believed in Xiao Ran's skills.

I think there should be no problem with the current coal.

"Your Majesty, it may be unsafe. For the sake of the dragon's health, I'd better go outside and burn it!"

"I believe in the technology Xiao Ran provided, and I also believe that you, Ananda, can do it well."

Zhang Ananda was a little touched by these words, "Yes, Your Majesty!"

There is coal in the stove, so just put the coal in and it will burn quickly.

Li Shimin did not look at the memorial, but stared at the coal.

"Good, good... no large amounts of smoke and dust, no pungent smell." Li Shimin knew this was feasible.

The pungent smell comes from sulfides.

It basically doesn’t exist now, so it’s actually not a big deal if there is a little problem.

In this era, most houses were made of wood and were more or less ventilated.

The imperial palace is larger, so the impact is smaller.

Looking at the burning coal in the stove, Li Shimin was in a good mood.

"Go, call Fang Xuanling and Wei Zheng over." Li Shimin asked Fang Xuanling and Wei Zheng to take a look.

"Yes, Your Majesty!"

Fang Xuanling and Wei Zheng also had their offices in the imperial palace, near the Taiji Hall.

Soon the two arrived at the Tai Chi Hall.

"Your Majesty, I pay my respects to you!"

"No need to be polite, come and sit down!" Li Shimin pointed to the cushion.

"Thank you, Your Majesty!"

"Do you smell anything?" Li Shimin looked at the two of them.

"It seems to have a pungent smell, but not strong." Fang Xuanling felt it.

The taste is a bit obvious.

"Look what this is." Li Shimin pointed inside the stove.

Fang Xuanling and Wei Zheng looked at the stove and then at Li Shimin, but found nothing wrong.

"Your Majesty, is there any problem with this?" Fang Xuanling didn't feel anything different.

"There's no charcoal in the stove." Wei Zheng discovered the problem.

Fang Xuanling then noticed, "It really isn't charcoal... Your Majesty, have you found a solution?"

"This is coal!" Li Shimin pointed and showed joy.

"Coal? How could it be coal?" Fang Xuanling was a little confused.

This is different from the coal we know.

"I have a way to turn coal into this. If it's coal like this, can it be used?"

"If it is at this level, it can certainly be used. It has a smell, but it does not affect anything." Wei Zheng also said.

"Hahaha!" Li Shimin laughed. "There's so much coal south of the city. It can be used after a little processing. The price of charcoal nearby will definitely come down."

"Your Majesty is wise. I didn't expect that coal could be like this." Fang Xuanling was also happy.

"The most urgent task is to allow more such coal to flow into Chang'an City and let more people use such coal. I just don't know what the price will be." Wei Zheng looked at Li Shimin.

"It is definitely much cheaper than charcoal. I think coal is more durable than charcoal. The only downside is that it still has a bit of smell." Li Shimin felt that there was a flaw.

"This is not a big deal. It's acceptable." Fang Xuanling looked at Li Shimin and asked, "Your Majesty, who would be the most suitable person to handle this matter?"

"You assist the prince in doing it. I will tell him how to deal with the coal in detail." This kind of thing is a great achievement, and Li Shimin will definitely let Li Chengqian do it.

"Yes, Your Majesty!"

"The sooner this happens, the better. There's no time to waste."

"Your Majesty, do you need a lot of manpower?" Wei Zheng asked.

"Both coal mining and coal processing require manpower, so there must be quite a few..." Li Shimin suddenly laughed, "The refugees from Chang'an can be arranged to work there!"

"Hahaha! Kill two birds with one stone!" Li Shimin was happy!
