Yecheng, inside the palace of King Wei.

"Hahaha, this New Year can really be said to be a double happiness for Da Wei!"

In the main hall of the Wei Palace, Cao Cao laughed loudly at Xun Yu, Jia Xu, Xu Chu and Xiahoudun.

"Lord Wei, I don't know where the joy comes from?"

Xun Yu asked Cao Cao suspiciously.

Not only Xun Yu, but Jia Xu, Xu Chu, and Xiahoudun in the palace hall of Wei Wang were all confused.

This Goguryeo hasn't started to fight yet, why is it double happy?

Then Cao Cao handed the letter sent by Lin Chuan about the cast iron cannon to Xun Yu and the four of them to circulate one by one.

It wasn't until the letter returned to Cao Cao's hands that Xun Yu and the four of them understood what Cao Cao was talking about.

"Hahaha, what Lord Wei said is good, Da Wei is really a double happiness this year!"

Xun Yu, who had read the letter, stroked his beard and laughed.

Xiahoudun was even more excited, and then said to Cao Cao: "Lord Wei, if the extremely powerful cast iron cannon that Mr. Lin said is really successful, then it will be as simple as eating and drinking water for the Great Wei soldiers, hahaha!" ”

Xiahoudun, who was born as a military general, suddenly doesn't want to continue to sit in Yizhou, anyway, Yizhou is developing very well now, it is better to go to Youzhou to see with his own eyes how this cast iron artillery will collapse the city of Goguryeo in the future.

Xu Chu still didn't believe it and said: "It's not that I don't believe Mr. Lin, but if the power of this cast iron cannon is really as Mr. Lin said, it's really outrageous!" ”

When Jia Xu heard this, he immediately smiled at Xu Chu and said, "Zhongkang, Mr. Lin never says big things. Since Mr. Lin said that this cast iron cannon can be built, then it must be built! ”

When Xu Chu heard what Jia Xu said, he just wanted to refute it, but he remembered that the grenade that was so powerful in the decisive battle of Chibi was also from Lin Chuan's hand, so he didn't say anything more.

"Everyone has a point, whether this cast iron cannon is really as powerful as Mr. Lin described in his letter, I believe we will be able to see it with our own eyes in a short time!"

As soon as he thought of being able to conquer the city of Goguryeo with cast iron artillery, Cao Cao wanted to see the cast iron cannon as soon as possible.

Then Cao Cao thought of Pu Yuan, who continued to preside over the research and development of grenades and firecrackers outside Yecheng City, and he had not been to Yecheng R&D base for a long time.

To put it simply, Pu Yuan is not yet able to mass-produce grenades and firecrackers while maintaining unified power.

After Cao Cao and the five people finished talking about cast iron artillery, they naturally turned the topic to Goguryeo.

"Recently, I heard Zhongde mention two of Mr. Lin's students, Jiang Wei and Jiang Boyo and Deng Ai Deng Shizai, who performed very well in the Youzhou camp, it seems that Mr. Lin is a famous teacher and a high apprentice!"

Cao Cao mentions Jiang Wei and Deng Ai, and then goes on to talk about the battle plan against Goguryeo.

"Now that Goguryeo has been plundered by 100,000 Xianbei cavalry led by Kebineng, all the people and soldiers of Goguryeo have gathered in the city, with Zhongde personally leading the troops, plus Jiang Boyo and Deng Shizai, two powerful generals, this king feels that he may not have to wait until after this year's spring ploughing to break Goguryeo."

After Cao Cao finished speaking, Xiahoudun continued: "What Lord Wei said is true, if you add the cast iron artillery mentioned by Mr. Lin, as long as spring comes, Great Wei can attack Goguryeo in a big way!" ”

Xun Yu and Jia Xu also nodded again and again when they heard this.

"After conquering Goguryeo, the Great Wei can not only obtain a large amount of fertile land suitable for cultivation, but also surround the Xianbei tribes, which will be more convenient for the Great Wei to subdue the Xianbei in the future."

Xun Yu also analyzed the benefits of the Great Wei's capture of Goguryeo.

"If Goguryeo is captured before today's spring ploughing, then the Great Wei will have more than half a year to migrate the people of the Great Wei to Goguryeo, and with the help of the Hanzhong Chamber of Commerce, it will take a year to completely digest the land of Goguryeo!"

Jia Xu then gave his own views on the occupation after the capture of Goguryeo.

Only Xu Chu sighed silently on the side that he couldn't go to Youzhou to fight against Goguryeo.

"Hahaha, exactly! That's why this king said that this year is really a double happiness for Dawei!

As long as there is no news of the alliance between Goguryeo and Buyeo from Zhongdeok's side, then regardless of whether the cast iron artillery is successfully developed or not, this king will let Zhongdeok lead the army to attack Goguryeo in a big way when spring comes, and strive to completely digest the land of Goguryeo within this year, as Wenhe said!

Then get ready to take in Xianbei!

There is no need for any other forces to exist on the side of Great Wei now! ”

Cao Cao no longer has to hide his ambitions at this time, and the powerful Great Wei makes Cao Cao no longer have to hide his ambitions!

Dawei, which has been vigorously developing for seven years, is just to be a blockbuster!

At the same time that the expansion plan of the Great Wei was set in the palace of the King of Wei, Lin Chuan and Cao Jie also personally led the craftsmen of the Hanzhong R&D Center to set off for Yecheng with Chen Yuan and Master Lu.

In addition to the necessary rest, Lin Chuan and his party did not delay much on the road, and they had already arrived in Yecheng five days later.

After coming to Yecheng, Lin Chuan asked Chen Yuan and Master Lu to take the craftsmen of the R&D center to rest temporarily in the Yecheng branch in Yecheng.

Later, Lin Chuan and Cao Jie came to the palace of the king of Wei together to meet Cao Cao, the king of Wei.

After Lin Chuan and Cao Jie came to the palace of King Wei, they came directly to the side hall where Cao Cao handled government affairs without the need for the palace guards to pass the message.

"Meet Lord Wei!"

"Meet my father!"

After Lin Chuan and Cao Jie came to the side hall, they greeted Cao Cao one after another.

Cao Cao suddenly saw Lin Chuan and Cao Jie, and after being stunned, he smiled at the two of them in great surprise: "Hahaha, Mr. Lin and Jie'er really gave this king a big surprise, hahaha!" ”

Xun Yu and Jia Xu, who were discussing with Cao Cao in the side hall about how to move the people of Great Wei into Goguryeo as soon as possible after capturing Goguryeo, so that Xun Yu and Jia Xu, who could digest all the land of Goguryeo this year, also greeted Lin Chuan and Cao Jie with a smile at this time.

After everyone greeted each other, Cao Jie excused himself from the fatigue of the journey and went back to rest first.

Lin Chuan, Cao Cao and others were left to continue to discuss things in the side hall.

After Cao Cao saw Lin Chuan, he immediately asked about the cast iron artillery after greetings.

"Mr. Lin, this king, Wen Ruo and Wen He, after seeing the cast iron cannon described by Mr. Lin, they are all curious about this powerful cast iron cannon, I wonder if this cast iron cannon has been successfully manufactured now?"

Xun Yu and Jia Xu were also looking forward to Lin Chuan's answer on the side.

"Lord Wei, not only have cast iron cannons been successfully manufactured in Hanzhong, but I now have the test data of two cast iron cannons in my hands!"

Lin Chuan said loudly to Cao Cao, Xun Yu and Jia Xu, and the three of them were immediately surprised when they heard this.
