Specially customized carving knife, when carving this object, it feels like carving a seal.

The tinsmith and the housekeeper Uncle Fu watched Cheng Saburo scratch around with a carving knife in a daze, and after a long time, he nodded with satisfaction.

"Just this kind of lead and tin ingots, get me 10,000 or 20,000 pieces first, the sooner the better, by the way, you can make as many as you can the day after tomorrow, you can send as many as you want."

Remember, the size has to be the same, or I won't pay. ”

Hearing this, the tinsmith who had been pounding for a whole day for these lead and tin ingots was overjoyed.

"Thank you Cheng Sangongzi, please rest assured, the villain will definitely do as you instruct, and he will definitely not go on a business trip."

Uncle Fu, the housekeeper, said to the old tinsmith.

"Whether or not you will travel to the pool, it is at stake in the reputation of your own workshop.

If you want to cooperate with my third son, then cheer up and send the finished lead and tin ingots as soon as possible, understand? ”

When Uncle Fu, the housekeeper, sent the tinsmith out of the door, Cheng Chubi took out his own sheet about lead movable type printing and what he needed to do.

Look at them one by one, and then add new notes at the end to prove that those things are done, those are in progress and what else is not heard yet.

As for the ink matter, Cheng Chubi really didn't feel at ease about leaving it to others, so he decided to experiment by himself.

Because he remembers seeing that kind of ink when he was a child in school and helping the teacher with that kind of manual printing machine to print exam papers.

He remembered that if the ink was too much, it would not only cause the handwriting to appear on the exam paper, but also a stain of oil around the handwriting.

Only then did I know that the reason why ink is called ink is precisely because kerosene and a certain proportion of vegetable or animal oil are mixed into it.

Cheng Chubi took out the fire oil that his eldest brother had gotten, which was actually an asphalt mixture that seeped into the ground, which could be regarded as a reserve material in the Datang arsenal.

Asphalt is originally gelatinous, and then mixed with a certain percentage of grease and, of course, ink.

After the reconciliation came out, Cheng Chubi tested the lead and tin ingots that he had left behind and were carved messily.

After repeatedly looking for a suitable ratio, he spent three days behind closed doors, during which he only went to the Wei Palace.

admired the painful expression of King Wei of Michelin, and then took out the authority of the attending doctor and taught His Royal Highness King Wei a hard lesson who actually ate greasy food during the recuperation period.

Then continue to nest in the small courtyard, continue to trial and error, and finally get a kind of ink ratio that can be glued to the lead-tin movable type, and then can be more clearly extended on the paper.

Although the handwriting printed by Cheng Chubi was obviously too much ink, Cheng Chubi couldn't help but laugh excitedly.

I finally proved that my memory was correct, and the research direction was correct.

#####

Cheng Chubi walked out of the door satisfied, and saw Deng Chengxin and Zhang Jin.

He is still tirelessly performing gallbladder extraction and cecal removal operations on newly purchased chickens and rabbits.

After walking up to him and looking at it for a few moments, and after a few words of encouragement, he staggered towards his resting yard.

After three days of research, he felt that his whole person was about to be hollowed out.

Although the ink has only achieved initial success, it can be used for testing, and a batch of lead movable type has already been received.

Cheng Chubi has asked the housekeeper Uncle Fu to find the old driver who carved the seal to engrave the seal, and the paper is stepping up the development of new paper according to the process and formula he gave.

And the carpenter is also conscientiously making the cylinder printing machine, everything is so real, but why is there a bubble in front of Teniang?

Cheng Chubi watched with a bewildered expression as a bubble that flew up from outside the wall, took off and then slowly landed, breaking down the sunlight on its surface to form a beautiful rainbow......

Then, a cheerful laugh was heard.

"My bubbles flew the highest, and they all flew over the wall." This is Cheng Lao Wuyang's proud voice.

"My biggest, the bubble I blow out is the biggest......" This is Cheng Laoliu's stinky child's voice.

Cheng Laosi, as his elder brother, is naturally unwilling to be left behind. He stretched out the straw pipe and poked the soap soaked in the copper basin, while speaking indignantly.

"You two wait, look at me, super invincible big brother!"

Cheng Laosi saw the third brother with a black face and poked his head out of the courtyard, and his face turned pale in an instant.

"What the hell is Super Big Three?" Cheng Laowu, who was facing away from the courtyard gate, asked with a confused expression.

"The third brother is here, run......" Cheng Lao Liu is worthy of being a very righteous little brother, and he ran out like a rabbit off the string.

Then Cheng Laosi also twisted his ass and ran away, unceremoniously throwing Lao Wu in place.

"Third brother, I didn't do it, it's the fourth, it's the fourth brother who stole the soap from your house, it has nothing to do with me."

Cheng Chubi looked at the water in the copper basin with a black line on his face, and there was a piece of soap in the water that had been reduced by at least half of its size.

He remembered that the soap he had just opened yesterday was his favorite mint-scented soap.

"You three little bastards!" Cheng Chubi exploded directly, and grabbed Cheng Lao Wu's ears with great skill.

"Cheng Laosi, Cheng Laoliu, don't give me a chance to get back, if you don't come back, believe it or not, I'll sue my mother!"

With Cheng Laosan's roar like thunder, Cheng Laosi and Cheng Laoliu could only run back in disgrace.

With an honest appearance of bowing down and confessing their guilt, these three little bastards are not afraid of the sky or the earth, they are afraid that their mothers will take their eyes.

Well, even in front of his father, even if these three boys are beaten, they are still naughty.

But when facing his mother, he was as docile as three kittens.

#####

A quarter of an hour later, three bear children with red ears were copied from a branch, and the hideous-looking Cheng Laosan supervised the blowing of bubbles there.

"Today, if you brothers don't finish blowing this basin of water, see if I beat you up."

"Third brother, my mouth is sour, can you rest and blow again......" Cheng Laoliu looked at Cheng Chubi pitifully.

Although it's fun to blow bubbles, it's fun, but now it's not fun to be held by the grumpy black-faced third brother to blow bubbles.

"That's right, third brother, we know it's wrong, we must not blow bubbles next time, okay."

At this time, Cheng Chubi heard the familiar footsteps coming, and when he looked up, he saw his mother walking towards this side angrily and funny.

I could only throw away the branch in my hand and salute respectfully to my mother. "I've seen my mother."

"Mother, the third brother beat me." The expected grievances came as scheduled.
