Three to two months.
Shen Kuo had achieved such results.
Cao Ang was very satisfied and decided to increase his investment.
An investment in science was an investment in the future.
Although gunpowder weapons might not be of much use in internal wars.
However, in the long run, this was a project with potential and prospects.
Near Huaxia.
Barbarians were everywhere.
The historical tragedy of the Five Barbarians mustn't be repeated.
The flags of the Mengyuan and Manchu would no longer be planted in the Central Plains.
The person who had been impacted and changed the most during this visit to the Academy of Sciences was undoubtedly Xun Yu.
For the first time, he realized the value of the " Exotic Skill ".
He had also learned many advanced thoughts from Cao Ang.
These were all valuable thoughts that could not be learned from the books of sages.
Cao Ang returned to the Prime Minister's Mansion.
He opened the system and took a look.
His Fate had already reached 3,000 points.
There was no need to buy agricultural products for a short period of time.
It was better to use this bit of luck on him to extract Heroic Souls.
Cao Ang did as he said.
Immediately draw.
" You have obtained the Heroic Soul of Zheng He!"
"You have obtained the Heroic Soul of 'Luban'!"
" Obtained Ou Yezi's Heroic Soul!"
"Interesting," Cao Ang muttered to himself.”
Zheng He.
The greatest navigator in China.
He was over a hundred years older than the West's Colombus.
In the future, he would unify China.
If he wanted to explore the overseas world.
Then Zheng He would be very useful!
Cao Ang kept Zheng He's Heroic Soul. He was thinking of finding one or two other Heroic Souls in the future to fuse with Zheng He so that he could nurture the strongest navigator in history.
Lu Ban and Ou Yezi were both craftsmen.
The former was known as the ancestor of carpenters and craftsmen in the world.
Lu Ban was very skilled in construction and had a deep understanding of civil engineering.
He specialized in creating all kinds of intricate mechanisms and was the best craftsman in China.
Ou Yezi was different from Lu Ban.
He was a great grandmaster in the field of forging.
He was especially proficient in smelting all kinds of metals.
He had forged many divine weapons that left their names in history.
Cao Ang felt that if Lu Ban and Ou Yezi complemented each other, they would definitely become a peerless master craftsman!
"Combining the heroic souls of Lu Ban and Ou Yezi!" Cao Ang said.”
" Combination successful. Please give it a new name."
"Cao Ban, also known as Zhi Zi."
A few minutes later.
A middle-aged man appeared in front of him.
This person was the future chief engineer of Cao Wei's civil engineering and smelting field. Cao Ban!
At the same time, he had Lu Ban's industrial design talent and Ou Yezi's talent in the use of metal materials!
His attributes were as follows:
————
[Name: Cao Ban]
[Loyalty: 100 (locked)]
[Advanced Attributes: Martial Force 45, Commander 19, Strategy 62, Political 30]
[Other Attributes: …(omitted)]
[Abilities: Grandmaster Craftsman (Rare Talent), Grandmaster Forger (Talent), Luban's Machine Book (Skill), Ou Yezi's Smithing Technique (Skill)]
————
Craftsman Grandmaster, Rare Talent, Industrial Design 100, Industrial Originality 100, Manufacturing Speed 50%!
Forging Grandmaster, Talent, Forging 100, Metal Smelting 50.
Cao Ang said," Ye Zi, you will temporarily work in the Academy of Science and assist Shen Kuo in improving cement and steam engines. When the time is ripe, I will put you in an important position."”
"Yes, sir!"
Cao Ban assisted Shen Kuo in his work.
Other than solving the industrial design and metal smelting problems.
At the same time, Cao Ban was also responsible for the manufacture and improvement of military equipment.
After the chief engineer took office.
There was an immediate effect.
For example, in the Spring and Autumn Period, there was a prototype of a catapult.
However, it only played an important role in the war during the Three Kingdoms period.
The Records of the Three Kingdoms, Records of Wei, Biography of Yuan Shao recorded: "Cao Cao sent a stone chariot to attack Yuan Shao's tower and broke it. Shao Zhong calls it the Thunderbolt Chariot."
It could be seen.
Cao Cao fought in the Battle of Guandu.
This was the first time he used a catapult.
Yuan Shao called it a thunderbolt car.
Although the trebuchets of the Three Kingdoms period had been greatly improved compared to the Spring and Autumn period, their accuracy was very unreliable. After Cao Ban became the chief engineer and designer of Xu City, the first thing he did was to improve the trebuchets that were currently being manufactured.
After Cao Ban improved it.
The range and accuracy of the brand-new catapults had been greatly optimized.
At this moment.
The latest news came from the front line.
Cao Cao's army successfully captured Pengcheng, Xuzhou.
Lu Bu had already retreated to Xiapi.
Xiapi City was quite sturdy, and the grain reserves were also quite sufficient. Lu Bu obviously wanted to fight a stalemate with the Cao army for a long time, and Lu Bu was holed up in Xiapi City. Even if the Cao army was strong, it would be difficult for them to break through in a short time.
"We've reached Xiapi so quickly?”
"Lu Bu is weaker than I thought. Or should I say, Yue Fei, Guo Jia, and the others performed better than I thought!”
Cao Ang pondered for a moment.
He made a decision,"Reinforcements for Xu Prefecture!"”
Lu Bu was forced into the last line of defense.
Once Xiapi City fell, he would be completely defeated.
Therefore, he had no choice.
Lu Bu would definitely defend to the death.
This man has the courage of ten thousand men, one against a hundred, regarded as ordinary.
He had ten to twenty thousand soldiers under him, and they were guarding the city. It would be difficult to win quickly.
Cao Ang decided to lead 10,000 troops to the front line and fight a decisive battle in Xiapi. He had to take down Xuzhou as soon as possible. On one hand, he could reduce the risk of trouble, and on the other hand, he could reduce the losses and preserve his strength.
