The morning sun had just risen, and the mist hadn't dissipated when Leonardo's door was pushed open from the outside.

"Morning, Leonardo?"

Francis' lazy voice came from outside the house: "Why didn't you close the door?" Leonardo's cold voice came from inside: "Where did you go?" In the meantime, a huge piece of drawing paper was spread out on his desk, and he was carefully drawing something on it with a ruler.

"Go out and in.

Francis shrugged, and then moved over curiously: "Is this your new painting?" Leonardo raised his head, glanced at Francis, and stretched out his hand to him.

"what?"

"Give me a drink.

Leonardo said. Pointing to the honey limoncello held in Francis' hand. The bottle is hand-sized only. Ice was added inside, and a thin layer of ice dew hung on the wall of the bottle. Francis shrugged and handed the wine bottle to Leonardo: "The master's ice cellar still has a lot of Lai Ruo...how about I get you some more?" Leonardo took a sip and suddenly glanced at Francis .

...you didn't steal it, did you? "

"Hey, I asked the master, okay?"

Francis said dissatisfiedly: "I always have to visit Lalfam from time to time. After all, leaving him in the ice cellar...it is easy to accidentally freeze to death.

"But you went to Violet Night last night. The black-haired boy glanced at Francis and said calmly.

…Hey, freeze to death and freeze to death. It's just that there is one less scum in this world.

Francis' eyes flickered. He coughed lightly: "Besides, he's fine now." And you can still go and play with the lovely young lady all night? "

"My name is Pathfinder, Leonardo. The industry calls it Stepping Point. I have to go and see if they are with that **** named Yuanjing." Francis said righteously.

"Then stepped on the bed and stepped on it."

Leonardo laughed, took another sip of limoncello, handed the bottle back to Francis, and said casually: "Don't take Lorenzo with you tonight. If he gets sick at a young age , You see the Grand Duke must not hammer you to death.

Francis smacked his lips and whispered, "It's not like he hasn't been there before" Huh? "

"That's cool. Listen to you." Seeing Leonardo's stare, Francis immediately succumbed and began to change the subject, "Speaking of which, what are you drawing? It looks complicated enough." Leonardo He replied: "President Lawrence once insisted on an invention with me.

"President Lawrence?"

Francis frowned in confusion, thought for a while, and suddenly exclaimed: "President Lawrence of the International Chamber of Commerce? Do you know him?" He also has another name called An Luoxian. Leonardo nodded and added in his heart. This kind of thing will generate huge profits, and he only dares to sell it to his own people. That's right, the blueprint he is drawing is a Jacquard automatic jacquard machine that has been simply improved.

The so-called jacquard is a concave-convex pattern composed of interlaced warp and weft threads on the textile. General looms can only weave plain weave fabrics at most. Fabrics with complex patterns can only be woven with jacquard knitting machines. Jacquard knitting machines first appeared in China. After years of improvement, it has been changed from sixty sheds to twelve sheds, and then to a more advanced Hualou-style bunch-heald jacquard machine, which was introduced into the West along with the silk. Weavers must follow the pre-designed patterns in their minds, Lift a part of the warp at an appropriate position, let the shuttle pull if the weft of different colors passes through, leaving bumps and colors. And this requires fine handwork, and the semi-automatic flower building machine for jacquard weaving that has been used by weavers for many years without making mistakes, also requires two to three weavers. Only then can the jacquard weaving work be carried out smoothly. What Leonardo is designing is the Jacquard automatic jacquard machine, the predecessor of the difference machine.

The principle is that Biyiri follows the "flower book" idea of ​​Hualou Ji, but does not record patterns in the pattern of pattern boards and fountain tubes with complicated craftsmanship.

Instead, try to control all the warp movement with a row of decoy needles, and then press the perforated card on the needles, so that the needles only pick up specific warps every time they run.

The complicated jacquard I process is omitted. In order to drop the needle in three steps, move the shuttle and weft, and replace the next page of cards, the jacquard pattern can be recorded by a cheap, easy-to-replace and manufactured "punched card", and then a steam engine is used as a driving force. …he can make fully automatic jacquard knitting machines with 1200 to 1400 needles.

If he profited from the patent of this Jacquard automatic jacquard machine, or rather, the Da Vinci automatic jacquard machine, he could make a lot of money. Use this as a research on differential engines or even extension machines. Almost all scientific experiments will require big star calculations. For this reason, dozens or even dozens of people will be required to form a calculation team to minimize errors and omissions. But such calculations are too slow, dull, and primitive. If these countless calculations can be realized by Turing-complete computing machines, mankind will truly enter the era of rapid progress. The splendor created by centuries of civilization. Will be compared with the past thousands of years. He can create electricity, create a difference engine or even an analysis engine, and then leave the rest of the work to future generations. As stated in his mission mission. Just start a new era. Appeared only as the announcer of the new generation.

Before entering the electrical age, human beings who have computers will create a new and brilliant civilization. Waiting for people to use the many documents he encountered and left, and the many inventions he created to improve freedom, just as his mission stated—that is his mission in this life.

Francis actually couldn't understand the value and significance of the mechanical drawings in Leonardo's hands...but he unconditionally agreed with Leonardo's work.

He knew and trusted Leonardo's talents and his judgment from the bottom of his heart. So he just shrugged his shoulders and said no more: "So Lorenzo is coming back, would you go and meet him?" Leonardo shook his head: "No, I have to receive some people then. "

"A newspaper reporter.

He turned around and smiled slightly: "I'm going to ask Lorenzo to hold a press conference.

"About... the smuggling, murder, and treason of His Excellency Francesco de Pazzi.
