As soon as he returned to the Gaoling Marquis Mansion, he saw Cao Yan sitting in the hall with an iron face, Cao Liang saw that the situation was not good, and wanted to slip away after a salute, Cao Yan shouted in a deep voice: "Stop!" ”

Cao Liang had no choice but to turn around and say with a smile: "I don't know what my father commands?" ”

Cao Yan snorted heavily, slammed an account book on top of several cases, and said in a deep voice: "Look at the good things you have done, within three days, you actually squandered nearly a million dollars in the Grange, you say, there are so many children of the family in Jingshi, who can have such a loser as you?" ”

Liu Ying was originally dissatisfied with her husband's attitude and wanted to speak for Cao Liang, but when she heard nearly one million dollars, she was really startled, and hurriedly said: "Liang'er, what your father said is true?" What exactly did you do that would cost you so much? ”

Cao Liang looked at the account book, it is estimated that the cow steward secretly reported to Cao Yan, but it is normal to think about it, this time it cost eight or nine hundred thousand yuan to build a catapult to build a keel waterwheel and a crossbow, such a large amount of expenses, the cow steward will definitely not dare to hide it, and will definitely report it to Cao Yan.

"The child went to the Grange that day to play, found that although the land of the Grange is close to Luoshui, but can not be irrigated at all, this spring has been dry and rainless, the fields can not be cultivated, just a few days ago when the child went to the North Mountain to meet Ma Jun in the matter, Mr. Ma is a genius in the world, proficient in mechanical construction, so he invited him to the Grange, built a few keel waterwheels, can draw the water from the Luo River into the fields of the Grange, so that our fields can be transformed into high-quality watered land, grain production has increased by at least three or four percent, Although it costs a little more now, by the time the harvest comes, these investments can be recouped. ”

Liu Ying was very happy when she heard this, although millions of dollars is not a small and delicate amount, as long as Cao Liang is not allowed to eat, drink and have fun, she has nothing to worry about, not to mention that Cao Liang took the money to do business for the grange, and she raised her hands in favor.

"Liang'er really grew up, and I know that I can share the worries of the family, I said Xianggong, don't embarrass him, Liang'er is also doing the right thing, although the money is spent a lot, as long as it is not squandered and wasted."

Cao Yan sneered and said, "You don't have to be sloppy here, how much can it cost to build a few keel waterwheels?" What is your intention in building a catapult and a crossbow in the Grange? ”

Cao Liang couldn't hide it from Cao Yan, so he had to say: "Father, how about taking a step to the study to talk?" ”

Cao Yan didn't say anything, because the things that Cao Liang built in the Grange did involve military matters, and some things were still inconvenient to talk about in front of his wife and the people in the family.

So Cao Yan got up and brushed his sleeves away.

Cao Liang also wanted to follow him, but Liu Ying pulled him and said in a low voice: "Liang'er, if you have something to say to your father, don't make him angry." ”

Cao Liang said: "Mother, don't worry, I will say it well." ”

Entering the study, Cao Yan was already sitting there with a solemn face, and when he saw Cao Liang coming in, he said in a deep voice: "Can you say it now?" ”

Cao Liang looked left and right, the study was indeed very quiet, and there was no one around to disturb him, and he didn't have to worry about the ears on the wall, so Cao Liang said: "Did my father remember the secret edict?" ”

Cao Yan said with a straight face: "What the first emperor trusted, dare to forget, and always keep it in mind." It's just that what you did in the Grange, what does it have to do with the secret edict? ”

Cao Liang said in his heart, the relationship is big, the first emperor gave a secret edict, and the person he wants you to deal with is Sima Yi, I am doing these things now, isn't it to compete with the Sima family in the future to give you more chips?

However, Cao Liang couldn't say this clearly for the time being, saying that Sima Yi would be opposed, Cao Yan would not believe it at all, but would ask Cao Liang how he knew.

There's really no explanation for this!

So Cao Liang can't mention this matter to Cao Yan at all now, he has to say: "Soldiers, sharp weapons, Mr. Ma Jun used the genius of the world to design a catapult that is several times more efficient than the trebuchet used in the army now, and designed a repeater that is more powerful than the crossbow of Shu Kingdom, but it is not used by the imperial court. Father shouldered the last order of the first emperor, if it is really as the first emperor said, when there is a rebellion of ministers and the society is in danger, how will my father fight the chaos and suppress the thieves and help the society? ”

Cao Yan said in a deep voice: "If you really come to the time when Sheji is in danger, you will lead the cavalry battalion to die for your father, serve the country loyally, and never live up to the last order of the emperor." ”

Cao Liang said: "If it is really when the rebellious ministers and thieves plot against the rebellion and the society is in danger, my father can withstand the traitors sweeping the world with a battalion of people and thousands of soldiers and horses?" Therefore, the child wants to share his father's worries, and the child has already experimented in the grange, the new catapult is indestructible, even if it is as strong as the city wall of Luoyang, it is difficult to resist. Needless to say, my father has been fighting with the Shu army for many years, so he naturally knows that the crossbow of Shu is powerful, and the crossbow made by Mr. Ma is several times more powerful than the Shu crossbow. ”

Cao Yan couldn't help but groan, he has been in the army for a long time, and he is no stranger to things like catapults and bows and crossbows, although it is said that fighting mainly depends on morale, but advanced weapons are still indispensable, for example, the crossbow of Shu is indeed a powerful weapon, even the famous general Zhang He died under the Shu crossbow, the horror of the rain of arrows in the sky still left a deep impression on Cao Yan.

It's just that the Wei military top brass doesn't seem to be very interested in developing new weapons, and weapons like the Shu repeater have never been developed, let alone distributed to the army.

Cao Yan didn't expect his son to be so young, and his thoughts and worries were far beyond ordinary people, if the Xiao Cavalry Battalion was equipped with a crossbow, then the picture, Cao Yan didn't dare to imagine, absolutely exciting, absolutely shocking.

"I see. It's just that making ordnance is not child's play, and if someone impeaches them, it may be a big disaster. Cao Yan was a little apprehensive.

Cao Liang said: "That's why the child is cautious, the craftsmen recruited are mostly reliable people, and the catapult built has been demolished, and all the timber has been rebuilt into a keel waterwheel, even if someone tracks it down, it is dead and unproven." The child has already mastered the drawings of the catapult and can rebuild it in a matter of days if needed. As for the repeating crossbow, the child has already ordered people to hide in the underground secret room, even if a few are seen, it doesn't matter, pretending to be hunting weapons, it is estimated that no one will pursue them. ”

Cao Yan nodded at this time, which was a normal admission of Cao Liang's approach.

This made Cao Liang secretly relieved, the only person who couldn't get around this matter was Cao Yan, as long as Cao Yan was willing to agree, the next thing would be much easier.
