As soon as Zhu Yunxi heard Lan Yu's letter, he temporarily let the two of them go.

"My uncle wrote to me?"

"yes!"

"If you promise not to drive us back, I'll give you the letter!"

Zhu Yunxi ignored Zhu Yuan's condition.

"Don't ask me about conditions, and wait until I read the letter before deciding!"

Zhu Wei didn't dare to talk to Zhu Yunxi, and immediately took out the letter from his arms.

Zhu Yunxi snatched the letter, and then looked at it seriously, the more he looked at it, the tighter his brows wrinkled.

It turned out that Lan Yu didn't know where to find out that Zhu Di, the king of Yan, had bought fine iron privately, and made weapons and armor privately in Beiping City, so that he could be careful of precautions, and found an opportunity to tell the imperial grandfather and let the imperial grandfather cut off the military power of Zhu Di, the king of Yan.

He also told himself that the fief of Zhu Value, the king of Liao, was in Liaodong, and he could be used as a vassal king to contain Zhu Di in the future, so that he must have a good relationship with Zhu Value.

Zhu Yunxi read the letter and sighed in his heart.

He suddenly understood a little why the imperial grandfather wanted to kill Lan Yu. This is indeed not a fuel-efficient lamp, and it wants to interfere in the affairs of the royal family.

It's just that he ignored one point, Yan King Zhu Di's fine iron was sold by him Zhu Yunxi!

If he, Zhu Yunxi, can't even deal with Zhu Di, why is he in charge of the world of the Ming Dynasty?

Besides, the future battlefield is to fight for fire, and it is useless to engage in a bunch of swords, guns, swords, and halberds, and it is not enough to blow up a shell yourself.

Zhu Zhi and Zhu Quan saw Zhu Yunxi's brows tightened, and immediately came over, wanting to see what was written in the letter.

Zhu Yunxi dared to let these two goods see it, hurriedly put away the letter, and then took out a box of matches to burn the letter.

Once the imperial grandfather knew the contents of the letter, Lan Yu's fortune was explained.

"If you two want to stay, just stay!"

"But be cleared in advance, you are not allowed to mess around, and you must bring enough guards with you when you travel."

When the two saw that Zhu Yunxi finally agreed to let them stay, they immediately became elated.

Then, the two washed up at the prefect's yamen, changed into a set of clothes, and led a few guards to go on a tour of the mountains and rivers.

Seeing the impatient appearance of the two, Zhu Yunxi even felt that he had been deceived. The two of them shouldn't have run away from marriage, but just want to come out and have fun, right?

Jinling Forbidden City.

Lao Zhu was secretly relieved when he received the secret music from his eldest grandson, knowing that these two rebels had run to Suzhou City.

He really beat his son, but he also felt really sorry for his son.

After learning that Zhu Zhi had abducted Zhu Quan and sneaked out of the capital, without even bringing a guard with him, Lao Zhu was also nervous and didn't sleep for several days.

Now that he knows the whereabouts of the two, the big stone hanging in his heart has finally landed.

Lao Zhu hesitated slightly, took out a blank fold, and wrote a letter to the eldest grandson.

First of all, I asked how things were going in Suzhou, and whether they could go smoothly. Then I cared about his body and asked him how much he ate and slept every day. Finally, he told him to pay attention to safety, not to be afraid of trouble when going out, and to bring as many people as possible with him.

Finally, at the end, he mentioned the matter of the two rebels.

"Hold your two uncles in custody, and then send the brocade guards to escort them back, and don't allow them to toss around!"

When Lao Zhu Lin was about to seal the fire paint, he thought about it and opened the fold again, and added a sentence on it.

"Little rebel grandson, let's come back almost, you don't want to participate in the autumn military exercise, don't you even want to come back for our birthday?"

After Lao Zhu finished writing the last paragraph, he sighed helplessly.

Because he knew that the rebel grandson would not listen to him, and this last paragraph was destined to be taken as a deaf ear by the rebel grandson.

But isn't that what life is all about?

When the child grows up, he is destined not to listen to his elders.

Lao Zhu ordered Qin Deshun to seal the letter with fire paint, hand it over to Jinyiwei and send it out, and walked out of the Qianqing Palace with his hands behind his back.

At night, the Forbidden City was pitch black, with only a few fires.

The incense of the Taimiao and the ancestral temple is royal

The kitchen fire in the dining room, and the lights in the Qianqing Palace.

Zhu Yuanzhang didn't like this kind of oppressive darkness, and wanted people to light up the entire palace, but he felt that it was too wasteful, and he suppressed this idea again.

Just as he was about to order someone to carry a lantern and take him around the city wall, he suddenly saw a row of lights on the side of the prince's mansion.

The row of lights was so bright that he felt a little dazzling.

"What's the situation in the Prince's Mansion, isn't it a fire?"

Qin Deshun explained with a smile when he heard this.

"It is said that the imperial grandson stole the divine thunder from the sky, which is the light emitted by the power of the divine thunder, called electric light."

"Electric?"

When Lao Zhu heard this name, the curiosity in his heart was instantly aroused.

"Let's go!"

"Let's see!"

"No!"

When Lao Zhu came to the Prince's Mansion with his escort, Zhu Yunxi was clapping under the light bulb.

"Wow!"

"It's so beautiful, the third brother is so powerful, he really stole the thunder and lightning!"

"The third brother is mighty, and the third brother is domineering!"

Lao Zhu looked at the light bulb hanging on the beam of the house, emitting orange light, and his eyes were rounder than the light bulb.

"What is this?"

"How can he shine?"

When Zhu Yunxi heard the voice of the emperor's grandfather, he was so frightened that he hurriedly shrank his neck, and then tiptoed over to salute Lao Zhu.

Lao Zhu waved his hand impatiently.

"Excuse me!"

"Tell the imperial grandfather, what is this thing, why can it shine, isn't it the pearl of the night?"

"Back to Grandpa, this thing is not a night pearl, it is a thing called a light bulb."

"It is said that electricity can only be lit by electricity, but what is electricity......

"Mabo!"

Zhu Yunxi was stunned as soon as he mentioned the details, and hurriedly resorted to summoning Dafa.

Although Zhu Yunxi had already sent him to study in the Hope School, Zhu Yunxi was a well-known scumbag, never listened well in class, and sometimes organized classmates to skip class and skip school.

Therefore, he only listened to a general knowledge of a lot, and he couldn't tell the details at all.

Ma Boke is Zhu Yunxi's founding disciple and his favorite student. He is the only one of all the students in the Hope School who is proficient in mathematics, physics and chemistry and can draw inferences.

Therefore, Zhu Yunxi entrusted him with all the research and development work of electrical appliances.

Generally speaking, the biggest problem in the development of science is "thinking", that is, thinking of possible needs based on existing principles.

However, Zhu Yunxi read a lot of science books through the Dafa of "Dreaming into the Divine Machine", directly skipped this step, and directly fast-forwarded to the link of targeted research and development and targeted application.

In addition, the application of electricity is less difficult than the research and development of steam engines, as long as the formulas and theorems are studied clearly, the rest is to wind the coil, study the enameled wire and other simple processes.

As for the trial and error link of the light bulb, it was directly canceled, and the tungsten filament was used for experiments in one step, which was 10,000 years ahead of Edison.

Therefore, the modernization of electrical appliances in the Ming version can be possible.

However, with the current industrial strength of Daming, it is not possible to mass-produce. At most, it's just a sample for some privileged people to enjoy in advance.

If you want to realize the Ming version of every household light telephone, even if it does not take a hundred years, there are at least a few decades to go.

After all, in another time and space, Galeries Lafayette Cixi also rode cars and trains, but until more than 100 years later, how many people still did not own a car.

The biggest key point in the popularization of technology lies in cost, not technology itself.

The technology that can't be popularized is the magic of Yin Qiao!

Zhu Yunxi is now playing a miracle skill, satisfying the extravagance of his personal life.

To this end, he specially built a small thermal generator, which was built a few miles away from the prince's mansion.

The reason why it was built so far away, also

Isn't it afraid that noise will disturb his sleep?

Ma Bo heard Zhu Yunxi's shout and walked out of the room with great reluctance. He's testing the circuit switch, and he really doesn't want to deal with this guy.

"Your Royal Highness the Fourth Emperor Sun, what's the matter with you......

"It's not me, it's the imperial grandfather, the imperial grandfather wants to know why this thing can be bright?"

"Oooh!"

"Wechen greets Your Majesty, long live Your Majesty......

"Excuse me!"

"Thank you, Your Majesty!"

"The main reason why this thing can light up is that when an electric current passes through the tungsten filament, it will produce an electrothermal reaction that will light up the tungsten filament......

Ma Bo said a lot, but Lao Zhu said that he just listened to the loneliness. What kind of current, what positive and negative electrodes, what kind of resistance, what the hell is this?

If it was the eldest grandson in front of him, he would have slapped him a long time ago. However, with Ma Bo in front of him, an outsider, he could only pretend to nod his head to hide his ignorance as an emperor.

"Not bad!"

"Very interesting!"

"Isn't it possible to save money on lamp oil and candles by using this item?"

"Yes!"

"But you need to burn coal, convert heat into power through a steam engine, and then convert the power into electricity by a power generator......

Lao Zhu saw that this guy started to talk at length again, and immediately interrupted him.

"Stop!"

"We just need to know it's cheap!"

"Hurry up and install this thing in our Qianqing Palace, so that the lamp oil and candle money in our palace can be saved a lot!"

Ma Bo wanted to say that this thing is much more expensive than lighting oil, and the current wires and light bulbs are not enough, so they may not be able to connect to the Qianqing Palace.

But just as he was about to speak, he was interrupted by Lao Zhu and signaled him to shut up, so he had to swallow the words back.

Lao Zhu walked around the light bulb a few times, and the more he looked at it, the more he liked it.

Bright, soft, no pyrotechnics!

If this is used in the Qianqing Palace, it will be too convenient when working overtime at night in the future.

"What other good things are in this palace of the rebel grandson?"

"Funny?"

Ma Bo thought to himself, this is science, this is progress, how can it be described as "good".

However, Zhu Yunxi didn't care about this at all, and hurriedly told Lao Zhu as if offering a treasure.

"Grandpa Huang, my third brother has a lot of good things here!"

"There are fans that blow the air automatically, lotus canopies that spray hot water, and ......."

When Lao Zhu heard Zhu Yunxi's words, he immediately took his hand and entered the main hall of the Prince's Mansion.

Since this main hall was struck by lightning, it was demolished and rebuilt by Zhu Yunxi.

Compared with the previous pure wood structure, this reconstruction has introduced a large number of cement, masonry and other materials.

The reason why Zhu Yunxi built it like this was not because of the degree of solidity.

Because the brick and concrete houses of later generations may not be stronger than the solid wood houses of ancient times.

The reason why he used bricks and stones was mainly because of the time cost and material cost of building the house.

Good wood is not cheap, even in the Ming Dynasty.

Comparatively speaking, masonry is much cheaper. Especially after Zhu Yunxi improved the brick kiln and had a steam engine to make bricks, the price of masonry dropped significantly.

After Lao Zhu led Zhu Yunxi into the main hall, before he saw the interior layout, he was attracted by the tiles under his feet.

"The ground is covered with ......."

"Grandpa Huihuang, this is a special tile ordered by the third brother!"

"Hiss......"

Lao Zhu gasped when he heard this, and shook his head in distress.

His Qianqing Palace only used ordinary floor tiles, and this rebel grandson was willing to use tiles to pave the floor?

"Isn't this too extravagant?"

Ma Bo is not only Zhu Yunxi's most proud student, but also Zhu Yunxi's biggest little fan

A few mouthfuls, even in the face of the emperor, he was not afraid at all.

"Your Majesty, this thing is made of new technology, and the price is extremely cheap, much cheaper than using stone bricks."

"Oh?"

"How cheap?"

"At this stage, the cost of a ceramic tile is about 300 yuan, and when the output is increased in the future, the price will definitely be lower."

"According to the Wechen Teacher...... The emperor's grandson's idea, the price of this thing must reach about 30 wen to have a universal price, and at this stage, it is just a paving for fun."

"Playing with the pavement?"

When Zhu Yunxi heard this, his nose was almost crooked. If it weren't for Ma Bo's tendons, or his eldest grandson's proud men, he would have ordered someone to scrape his ears.

Seeing that such a luxurious floor tile was only 300 yuan, Lao Zhu immediately retracted his gaze and looked at the huge crystal lamp hanging on the roof.

Under the glow of the light, the crystal exuded a charming color, and Lao Zhu's eyes were almost unable to open.

"This thing is also chic......

When Qin Deshun heard this, he immediately knew that the emperor was covetous, and he was worried and embarrassed to ask for it.

Therefore, he hurriedly pulled Ma Bo aside and muttered quietly.

"Ma Zhanshi, do you still have such a crystal lamp in your hands, and you can also install one for the emperor's Qianqing Palace?"

The so-called Ma Jens is Ma Bo's position in the Mandarin Palace.

Although he didn't want to be an official, how could Zhu Yunxi let his proud disciple not be a white body?

Therefore, it took a long time to search the East Palace before I found such an official position.

But Ma Bo's Ma Jens is just a name, which is convenient for him to wear a "whale suit" to wander around, and mix up the right to see officials without kneeling. As for the affairs of the Wenhua Palace, he didn't care at all.

I don't have time, and I don't have the mood to care.

When Ma Bo heard Qin Deshun say this, he immediately shook his head honestly.

"Nope!"

"There is only one thing, and every accessory on it is hand-blown by the people of the glass factory."

Qin Deshun saw that Ma Bo was so unenlightened, and he wanted to use a hammer to chisel his dog's head.

"Then you'll order them to blow one more set!"

"I'll pay for it!"

"Can't I pay for it?"

Marbo shook his head again.

"No!"

"Now the glass factory is working hard to produce glass windows, and I don't have time for this thing. If you want to do it, you have to wait for His Royal Highness the Imperial Grandson to come back, and with the Imperial Grandson's warrant, they can adjust the production schedule......

Lao Zhu heard the muttering of the two, and saw that Qin Deshun had eaten two closed-door soups in a row, and his face was a little unbearable.

"Qin Deshun, we don't have to beg him, let's build a glass factory by ourselves!"

As soon as Qin Deshun heard this, he knew that the emperor was really angry.

Otherwise, how could the emperor be such a thrifty person who gave birth to the idea of building a glaze factory for a lamp?

"The Emperor is angry!"

"The emperor's grandson is unparalleled in benevolence and filial piety, as long as he comes back, he will definitely ......."

Lao Zhu snorted coldly.

"That rebel grandson is also worthy of saying that benevolence and filial piety are unparalleled?"

"It's pretty much the same joke!"

"With such a good thing, not to mention giving us a set, but enjoying it yourself!"

"We really hurt his rebel grandson in vain!"

The more Lao Zhu spoke, the more angry he became, and the more angry he became, the more he felt that he was not angry. I happened to see a leather-wrapped chair next to it, and immediately sat down.

However, when he sat down, he felt as if it was empty, and the chair collapsed on the spot.

It wasn't until the chair stopped collapsing that Lao Zhu touched the handle in horror and shook it a few times on the chair.

"Huh!"

"This chair is kind of interesting!"

Zhu Yunxi also liked this chair very much, and said on the spot when he saw that the imperial grandfather praised the chair.

"Grandpa Huang, this is a soft chair with springs and goose feather cushions and the like, sit on it

It's very soft!"

When Lao Zhu heard this, a wicked smile suddenly appeared on his face.

"Could this rebel grandson be afraid that we will hit the board, so he pondered such a special chair?"

"Not to mention, this chair is really comfortable to sit on, even if your butt is swollen, it won't hurt to sit on, hahaha!"

After Lao Zhu laughed, he even began to wonder in his mind what reason to beat up that rebel grandson.

For example, step your left foot first when you enter the door?

This rebel grandson is too unfilial, the glass lamp and floor tiles are not dedicated to himself, and he is reluctant to even have a good chair, so he worries all day long that he does not eat well outside, sleeps well, and worries about what danger he encounters.

Lao Zhu rested on the chair for a while, and after relieving himself for a while, he started the treasure hunt again.

"Grandpa Huang, this is a fan that can move by itself!"

"Look, just press here, and it can blow the wind!"

Lao Zhu looked at the strange thing whirring and blowing a cool breeze in the net cover in front of him, and he was addicted to it.

Although it has passed the ambush now, the night is still a little stuffy, and with this little cool breeze, the whole person is panting a little smoother.

"That's a good thing, too!"

When Qin Deshun heard Lao Zhu's comment, he secretly added the fan to the list, and asked for it just when the imperial grandson came back.

"Grandpa Huang, my third brother's bed can still be heated!"

"It is said that as long as you press this switch, the bed will be warm in winter!"

"Grandpa Huang, this is the bathroom, just turn this to adjust the temperature of the water, and pull it out to spray hot water......

Lao Zhu looked at the lotus canopy with water spraying above his head, and then looked at the big bathtub on the side that could make people lie flat, and sighed again in his heart.

This rebel grandson is too good at enjoying it, right?

The bathtub we bathed in was still wood, and he actually burned a large bathtub out of porcelain!

Wait a minute!

What is this whole toilet-like thing, could it really be a toilet?

Zhu Yunxi saw the imperial grandfather looking at the toilet, and immediately sat down to demonstrate it to the imperial grandfather.

"Grandpa Huang, this thing is a toilet, every time you are done, as long as you pull the rope, water can be sprayed inside, and all the pickled things will be rinsed......

"Uh-uh......"

After seeing the "extravagance" of his eldest grandson, Lao Zhu said in his heart that he had been the emperor for decades in vain, and no rebel grandson would enjoy it.

So, he made an astonishing decision, he won't go back to the Qianqing Palace today, and he wants to stay in the eldest grandson's new house for one night!

However, after Lao Zhu stayed for one night, experienced the double baptism of a luxurious bathtub and shower, and experienced the flush toilet that perfectly fits the curve of his buttocks, he never mentioned the matter of returning to the Qianqing Palace, and has been relying on the prince's mansion.

There is no other reason, it is really too comfortable to live in this new palace, and there is a lot of joy here, and I don't think about it.

Every day, after reviewing the recital, lie down in the large bathtub and take a hot bath, and lie on the soft bed after soaking in the bath to sleep well, which is simply a beautiful enjoyment.

According to his logic, he has worked hard for decades, and it is time to enjoy it.

Besides, let's not live in vain, let's exchange the Qianqing Palace with the reverse grandson!

Lao Zhu has already decided, when the rebel grandson comes back, he will let the rebel grandson live in the Qianqing Palace!

Qin Deshun had already seen Lao Zhu's thoughts, and on the third day of Lao Zhu's residence in the Prince's Mansion, Qin Deshun pointed to the brand-new "Taisun Mansion" plaque hanging on the door of the Prince's Mansion.

"Emperor, the slave maid sees that this plaque is a little old, and the handwriting on it is not clear, is it time to change it?"

Lao Zhu looked at the plaque and nodded.

"You don't say that we didn't pay attention, this plaque is really a bit out of place!"

"Order someone to pick it up, and get a new one!"

"No!"

"Emperor, what's engraved on the new plaque?"

When Lao Zhu heard this, he hurriedly turned back to the house and wrote three big characters on the table.

Qin Deshun is naturally a good boast, what dragon flying phoenix dance, power through the back of the paper, faintly the sound of gold and stone, etc.

It wasn't until Lao Zhu's last pen was written that Qin Deshun read it out.

"The Temple of Heart Nourishment?"
