"Okay, you have the formula for gunpowder, and if there is nothing else, just retreat."

Seeing this, Zhu Yuanzhang also spoke.

It was getting late, and Zhu Biao had been guarding him outside the door for a day, so he should go to rest.

"The retainers retired."

Zhu Biao also had no ink, and after saluting respectfully, he turned around and left the Fengtian Palace.

After getting the things, he handed them over to Zhu Zi next, and what he promised Zhu Zi was done.

.......

Following.

Tongfu Inn.

On the second floor, Zhu Zi sat in the position where he met Zhu Biao for the first time, leaning against the window, drinking tea, and watching the people coming and going on the street below.

This kind of comfortable feeling is really good, and I can't experience this feeling in Qiongzhou.

Qiongzhou is not as prosperous as the imperial capital, but he believes that in a few years, the development of Qiongzhou will not be weaker than that of the imperial capital.

"Huh?"

Zhu Zi's eyes lit up and looked down.

It didn't take long for a noise to come from below, and Zhu Biao walked up from below, and under the leadership of the shopkeeper, he brought it to him.

"You can step down."

After Zhu Biao saw Zhu Zi, he also turned back to the shopkeeper and said.

"Yes, yes, yes."

The shopkeeper didn't dare to say much, and hurriedly left here.

Seeing that the shopkeeper had disappeared, Zhu Biao walked towards Zhu Zi.

"It's so early, it looks like it should be going well."

"Sit down."

As soon as Zhu Biao walked in front of Zhu Zi, Zhu Zi said with a smile.

Being able to come over so early is probably done.

"Of course, this is what you want, for you."

Zhu Biao nodded slightly, took out the formula of gunpowder from his arms, and handed it to Zhu Zi.

Early in the morning, after Zhu Biao got up, he immediately left the palace and came to the Tongfu Inn to find Zhu Zi.

"It's worthy of being a big brother, and it has to be you."

Zhu Zi took the formula of gunpowder, opened it and looked at it carefully, and then put it away with satisfaction.

The purpose of this trip is also achieved, and this is the main purpose of coming to the imperial capital, mainly for two purposes, one is the means of smelting iron, and a blacksmith shop has been mastered, and the second is to get the formula of gunpowder, which is also completed very well, and it has been successfully obtained.

The two purposes have been accomplished, so he can leave the imperial capital at any time and return to Qiongzhou.

"It's still your marrow washing fruit, which comes in handy, my father heard the formula I asked for gunpowder, and he hesitated at the time, but fortunately, it was the marrow washing fruit, otherwise it would be difficult."

Zhu Biao waved his hand.

He was just a matter of convenience, if he didn't have Zhu Zi's marrow washing fruit, then he couldn't get the formula for gunpowder so easily.

"Father has eaten the marrow washing fruit?"

Zhu Zi showed a puzzled look, listening to this meaning, Zhu Yuanzhang should have eaten the pulp washing fruit, and it will be like this when it has an effect, otherwise how can an unclear thing make Zhu Yuanzhang care too much.

"That's right, after my father ate the pulp washing fruit, the whole person was refreshed and looked a lot younger, and my father said that all the dark diseases on his body were cured."

"Thanks to your marrow washing fruit, my father's body has been greatly improved, otherwise if my father goes on like this, his body will not be as good as day by day, but it will be over."

"Didn't you give me a total of three marrow washing fruits, and two more, I want to take one for my father, and keep the remaining one for myself."

Zhu Biao nodded and said.

This idea was born after he took the marrow washing fruit, and after seeing Zhu Yuanzhang take it, he became even more determined to this idea.

Keep one for yourself, it's enough, and another one can be given to your father.

With my father's current body, eating another marrow washing fruit should be able to improve a lot.

"Big brother, I didn't say you, why are you stupid at a critical time."

"Does my father think that the marrow washing fruit you gave him is the last one?"

Zhu Zi sighed lightly.

Now Zhu Biao's thoughts, he can already guess, but he doesn't think he will let Zhu Biao do it.

"Yes, I told my father, I ate one, and the one for my father was the last."

Zhu Biao said without hesitation.

"That's right, let me ask you, if you are taking one out at this time, does it mean that you said before that it was the last one, and it was to deceive your father, that is the crime of deceiving the emperor, at this time, you are telling your father that it is the last one, will your father still believe it?"

"When the time comes, send someone to search and find your one from your house, is that another deception, this is a big crime, when you are in your father's place, there will be no integrity at all."

"Big brother, I know that you are for the good of your father, but my father has just taken a marrow washing fruit, and after taking the second one in a short time, the effect is poor, the two in your hand, keep it for yourself for the time being, and when I solve the problem of Haikou, when I return to the imperial capital, I will personally take out the marrow washing fruit to my father, just at that time, it has been a long time since the last time I ate it, and the effect at that time is very good."

Zhu Zi said with good words.

No matter what Zhu Biao thinks, he can't let Zhu Biao commit the crime of being stupid and bullying the king, but with a big mouth, it is not certain whether Zhu Biao can keep the position of the crown prince at that time, let alone sacrifice the credit of washing the marrow fruit now.

Maintain the status quo now, don't let Zhu Yuanzhang know, and the marrow washing fruit, that is the most important thing.

"yes, I didn't think of that."

"Eighth brother, thanks to you, otherwise I would have planted it."

Zhu Biao pondered for a while, reacted, patted his thigh and said.

has been in the court for so many years, he knows Zhu Yuanzhang's temper clearly, once Zhu Yuanzhang knows that he is bullying the king, it will be over, once it is very serious, if it is twice, it will be really cool.

Fortunately, he told Zhu Zi in advance, otherwise it would be really over, and it would be too late to regret it at that time.

"You are also concerned about it, you must take good care of the pulp fruit, and don't take it out unless it is a last resort, even if you take it out, you can't let too many people know."

"I believe that the eldest brother is also clear about the truth that wealth is not exposed, so I won't say more."

"Today, I still have to thank my eldest brother for getting me the formula for gunpowder."

Facing Zhu Biao's awakening, Zhu Zi also smiled.

can say clearly, that's the best, if it's too axial, then he can't help it, fortunately, Zhu Biao is a smart person, and he can make sense in one sentence.

"Thank you, what are you polite to the eldest brother, do you have any other needs, while my father is in a good mood now, I bring it up, and it is very likely that my father will agree."

Zhu Biao waved his hand and continued to ask.

While Zhu Yuanzhang is still happy now, it is the best time to put forward demand.
