In fact, there have been listening devices since ancient times, such as the listening urn mentioned by Mozi; There is also a kind used by the army of the Tang Dynasty, which is made of leather called 'empty deer'. It is said that 'mortals and horses travel 30 miles away, and their ears ring from east, west, north and south'.

But these are non-directional listening devices, which can only monitor the distance and size of the sound coming from the ground, and there is nothing you can do to listen to people in the distance.

So the Song Dynasty invented the listening tube. It is made of bamboos chiseled through the inner joints, and can be located underwater, underground, or hidden above the ground or in a house, for close eavesdropping on people's conversations.

Moreover, Zhu Zhen and Zhu Di also combined the advantages of the listening urn and the empty deer to improve the listening tube. For example, the flared toilet next door is actually a radio device......

~~

Next door.

King Ming beckoned the stone protector to sit down on a normal bamboo chair.

He himself sat on the toilet chair.

First, the toilet chair is on the left side of the table, and it is not the Yuan Dynasty now, but now the left is respected. Second, if the stone protector has a thorn on his cheek and brings up the toilet lid when he gets up, it will be too shameful.

Third, how can you let people sit on your own horses?

So it's better to sit on it yourself and rest assured.

Alas, in the final analysis, it is still young people who have no hair on their mouths and are not able to do things well. How can you combine a toilet and a chair for the sake of beauty?

Forget it this time, you won't be able to live for a few days. Next time, I will let them set up a special thatched house.

King Ming, who had already tasted the sweetness of the flushing toilet, thought.

"This time I go out, the situation outside is still deteriorating, and Huai'an can still breathe." Shi Chenglu's voice called King Ming back from his cranky thoughts. "If it weren't for a few boatloads of grain from the east, the villages would have run out of food."

"Oh." King Ming nodded and said, "Huai'an Mansion is the territory of the Ducao Yun Division, and we have formed an alliance. ”

"yes, that's great!" Hearing this, the stone protector said excitedly: "Then the follow-up materials can be boldly transported here from Huai'an." ”

"Yes, I have already talked to Nan Anhou, but I will ship it after dark." King Ming said in a deep voice: "Anyway, you hurry up, we have to start early." ”

"Oh?" Shi Protector was surprised: "Why? ”

"According to the information from Cao Protector's side, there are various signs that the crown prince will go north to Fengyang in the near future." King Ming lowered his voice and said, "And this was the news a few days ago, and now he may have set off!" ”

~~

Pitchers have ears.

Although King Ming lowered his voice, the brothers next door still heard what he said clearly.

Zhu Zhen glanced at each other, knowing that the eldest brother must have gotten the news of their disappearance, and hurried to Fengyang to find someone.

Alas, the eldest brother may die in a hurry...... The brothers are all sorry.

~~

In the room of the king of Ming.

Listening to King Ming's words, Shi Protector was also surprised. "Didn't you say that you won't leave until next month, why are you in such a hurry?"

"The situation in Xu is Zhongdu makes Zhu Hongwu feel uneasy." King Ming guessed: "We have killed so many people, and we almost captured the Forbidden City, we must have shaken the court!" ”

"That's for sure." The Stone Protector nodded.

If the two knew that their uprising had been weakened by the Yamen of the Ministry of Industry and the Zhongshu Province, and when it reached Zhu Yuanzhang, it had already become a small riot, and it was not even recorded in the living notes, I don't know what kind of mood they would have?

"So, Zhu Hongwu may also come to Zhongdu in advance?" Shi Protector asked again.

"Quite possibly." King Ming nodded and guessed: "The crown prince should be the first station for him, it may not take a few days, and he should also set off." ”

~~

Next door.

The brothers looked at each other again.

What, the father is coming too?!

This time, their first reaction was that their butts would not be beaten......

~~

"So fast......" Shi Protector's mouth was dry for a while, although he had been looking forward to the day when Zhu Hongwu came. But that day really came, and it was impossible for him not to be afraid.

"It's not a bad thing, don't forget, although we have only been here for a few days, the brothers have been here for more than a month." King Ming said: "There has been a lack of food and clothing for more than a month, and many people are still sick, and their morale has been lowered a lot. If it drags on any longer, it will have a greater impact on combat effectiveness. ”

"Hmm." Shi Protector nodded and said, "Then I have to hurry back to Linhuai and check if the excavation tools are ready; And some more gunpowder to make sure that nothing goes wrong when the time comes. ”

"No, you've been exposed." King Ming shook his head and said, "I'll let Cao Protector take charge of the destruction of the embankment, so you can concentrate on the logistics." ”

"Ugh." Shi Chenglu sighed unwillingly, and he couldn't see the happiness in his heart at all.

It's too dangerous to destroy the embankment, and you can't let the water wash away first. If they can't rush away, they will also face angry pursuit by officers and soldiers.

Moreover, it is too damaging to yin morality......

He wished someone could do it for him. Then he explained to the king of Ming:

"Please tell King Ming to tell Cao Protector that Han Yike of Linhuai County is a capable official, and after he took office, he did three things, repairing the embankment, repairing the embankment, or repairing the embankment! So don't take it lightly. ”

"Well, I know that." King Ming said in a deep voice: "Cao Protector is only responsible for the preliminary preparations, and when it's time to do it, I will personally take someone there!" ”

"Fight the rabbit with all your strength, so that it will be foolproof." Shi Chenglu breathed a sigh of relief and said with concern: "After the embankment collapses, King Ming must pay attention to safety." ”

"Don't worry, we'll have the boat ready." King Ming said lightly: "And the Marquis of Nan'an will lead his sailors to wait in the Garden Lake, once our side succeeds in breaking the embankment, they will immediately sail to pick us up, and then the fleet will go straight to the imperial tomb along the flood!" ”

"King Ming is really clever! I'm afraid that Liu Bowen can't compare. Shi Protector couldn't help but admire: "Everyone thought that our goal was the Central Capital City, but they didn't expect that our real goal was the Imperial Tomb!" ”

"When Zhu Hongwu arrives in Zhongdu, he will definitely go to sweep the grave of his father and mother." King Ming said to himself: "And his imperial tomb was built on the original grave of his father's mother, and the terrain was low-lying. Once there is a big flood, the middle capital city built on the high place will be safe and sound, but the imperial tomb will be flooded. ”

"What's even better is that at that time, all the troops will be on guard in Fengyang County, they never imagined that we will be in Linhuai County, where the garrison is empty!" Shi Protector said excitedly: "All kinds of surprises are superimposed, Zhu Hongwu is invincible?!" ”

"Hehe, in fact, there is another one that I can't think of." King Ming said lightly: "He didn't expect that he killed Liao Yongzhong and finally forced the Chaohu Water Master to rebel." Otherwise, relying only on us, even if the Seventh Army is flooded, I am afraid that we will not be able to take his life. ”

"Yes, yes, yes......" Shi Protector nodded, and said with a smile: "Can your subordinates congratulate King Ming in advance?" ”

"Let's wait until it's successful." King Ming kept his composure and moved on to the next topic:

"But whether it succeeds or not, there is only a dead end to stay in Fengyang at that time. So after we set off, we didn't go to Fengyang, and went directly south to Suzhou, looking for Luo Protector to contact those old Chengwang departments, as well as the anti-Zhu Hongwu Jiangnan landlords. I'll also be the first to go south and meet them as soon as I arrive......"
