Hearing the movement, Li Yuan rushed over quickly and asked Zhang Medical Order.

"What's wrong with my concubine?"

Zhang Yiling hurriedly saluted the big guys present before speaking.

"Congratulations to the emperor, congratulations to the empress, the empress is happy again..."

"...Are you happy?" Empress Changsun stared at the gray-bearded father-in-law who was already in his seventies.

Then he looked at Concubine Yuwen, who was slightly younger than him, and he didn't know how to describe his mood at the moment.

"Medical Zhang, you didn't lie to me, did you?" Li Yuan was also shocked.

"My lord, how dare I make fun of such an important matter." Zhang Yiling replied helplessly spreading his hands.

"Old man, this old man actually has a baby again?"

Li Yuan's expression was very strange. In his mind, he seemed to recall the days when he was solved by Cheng Sanlang.

After that, Li Yuan had a period of psychological shadow, and then he gradually regained his glory.

But after that, no children were born again, and Li Yuan, who had many sons and grandchildren, didn't care much about it.

But now, he was already in his early seventies, yet he was pregnant by Concubine Yuwen again.

"Respect to father-in-law, congratulations to auntie, this is really a good thing, I believe His Majesty will be very happy to know that he will have another brother or sister."

Eunuch Zhongbao, a rigid-faced eunuch, couldn't help showing a smile, and saluted the founding king of the Tang Dynasty respectfully.

"Respect Your Majesty, this can be regarded as the first time since His Majesty took over the Wanguoyuan Palace, it is a great joy to add children and words."

Seeing Concubine Yuwen's pretty face flushed, and seeing her daughter-in-law whispering something to Concubine Ai, she smiled happily.

Li Yuan couldn't help feeling relieved, stroking his long beard and talking happily.

"Hmm... It seems that the feng shui of this Wanguoyuan Palace is good, it prospers and benefits descendants.

It seems that at the beginning, the old man made up his mind to live in the land of Heluo for a long time, and he did it right. Hahaha…"

#####

Empress Changsun rushed back to the palace with joy on her face, and hurried to the Wencheng Hall.

It was just now that Fan outside the hall heard the exaggerated laughter of my husband coming from the hall.

"Wahhahaha... Well, well, it's actually there, that's great."

Empress Changsun couldn't help being a little dazed, no, how could my husband know that she didn't have someone rush back to report.

Just as she was thinking in her heart, Empress Changsun lifted the curtain and saw Cheng Sanlang and her beloved daughter Li Mingda were all there.

"Guanyin maidservant, you are here, come, come, my husband has good news for you."

Empress Changsun nodded and smiled at Cheng Sanlang before looking at her husband.

"Daddy, I will tell my mother..." Li Mingda was still a little embarrassed, and rushed towards his mother with a blushing face.

"Okay, okay, tell your mother yourself." Li Shimin stroked his long beard, and looked at his beloved daughter with great comfort.

I still remember that at the beginning, this girl was only so small, and she was about to become a mother in the blink of an eye, how time flies...

"Yes?" Empress Changsun looked at Li Mingda in her arms in shock, and then glanced at Cheng Sanlang next to her.

Li Mingda's face was pink, and he was still shy, and he gently plucked at his mother's skirt with his fingers.

"Well, I just found out..."

"This is great, husband, this is really double happiness..."

Empress Changsun caressed her daughter's blue hair affectionately, and smiled sweetly at her husband who was lamenting how time flies.

"???" Li Shimin and Li Mingda both lifted it up in unison, "You have white beard and white hair, you are also dyed, right?"

Immortal Yongning hurriedly bowed down to Cheng Chubi, and replied in a low voice.

"Mr. Cheng, villains are born with beards and hair. They started to have gray hair when they were ten years old.

Back then, when the villain was begging in Shuzhou, my master saw that I was already gray-haired at a young age.

Out of pity, this villain was accepted as a disciple, and now the villain has just turned thirty. "

Looking at this fake cow-nosed man with gray beard and hair at the age of thirty, Cheng Chubi narrowed his eyes and said.

"Your master was killed by the alchemy furnace back then, and the sky thunder you are doing in the temple now, it should be caused by a kind of alchemy formula, right?"

"Cheng Sangong's wisdom is indeed caused by a kind of alchemy formula, and the master's attainments in alchemy are extremely high.

Not only can it refine mercury and green vitriol oil, but it has also been researched for many years, and it has developed a formula that can ascend to immortality. "

"He was worried about being known, so he specially took the villain to an uninhabited valley in Qingcheng Mountain to practice alchemy. As a result, the alchemy furnace was blown up, and my master..."

Speaking of this, Cheng Chumo was immediately happy.

"Your boy Shaote's nonsense, alchemy can make thunder, you think you are a fool, Uncle Cheng?"

Cheng Chubi glanced at the eldest brother with a numb expression, and the second brother who was nodding beside him.

It seems that the level of science, education and culture of the old Cheng family still needs to be improved, otherwise how can the poems and books be passed on to the family?

"Mr. Cheng, the villain is willing to swear to the sky, if the villain makes a false statement, he is willing to be struck with thunder."

Cheng Chubi squinted his eyes and looked at this real Yongning, green vitriol, wait a minute, green vitriol...

"The green vitriol oil you mentioned will corrode steel?"

Hearing this, Master Yongning raised his head in astonishment, and nodded blankly.

"You can also refine the green vitriol oil?"

Cheng Chubi folded his arms and looked at this real Yongning Daoist.

When Master Yongning heard this question, his head nodded like a chicken pecking at rice.

"The villain will, the villain has followed the master for more than ten years, and my master has already taught the villain all his skills."

"Little man, in the mind of the villain, if Mr. Cheng wants it, the villain is willing to donate the pill recipe, just save Mr. Cheng and don't send the villain to the yamen."

After a short while, Cheng Chubi and his two elder brothers followed the real Yongning to the alchemy room in the backyard.

After Master Yongning pushed open the door of the alchemy room, he quickly fetched a jar no bigger than a palm, and held it carefully. UU reading www.uukanshu.com

"Master Cheng, this is the medicine that can make the sound of thunder."

"You only need to ignite the fuse made of paper with a torch, and after a while, the flames will soar into the sky, and sometimes there will be a thunderous sound and billowing smoke."

Cheng Chubi stared blankly at the small jar whose lid had been lifted, sizing up the ingredients inside, the corner of his mouth twitched.

I thought I had discovered the founder of gunpowder, but what I saw was only the prototype of gunpowder.

"What's the mess here? Where is Danfang?"

"Mr. Cheng, Danfang is here..." Master Yongning quickly took out a jade plaque from the collar, and clasped his little finger.

Unexpectedly, the school has a sandwich, and a small ball of silk fell out of it, Cheng Chubi raised his hand to take it.

"Sauer's salt, sulfur, charcoal, and even honey, Taiyi Yuliang?"
