Fang Xiaoru said after reading it, "Your Majesty, now that the Yan army has been detained in Dongchang for a long time, it is an opportunity for the imperial court, and the minister thinks that the generals of Liaodong should be urgently ordered to enter the Shanhaiguan and attack Yongping, and the generals should really cross the Lugou Bridge and smash Beiping." Zhu Di must go to Beiping and come back to the rescue, and the imperial court will be able to capture Zhu Di with a large army, attacking inside and outside. There are two ways to go today, one is that the emperor can write a letter to King Yan, appease him as one, disintegrate his upper and lower as two, go back and forth for a few days, and the emperor will plan and agree. Moreover, the minister heard that Zhu Di did not trust the prince, and the prince had made friends with the emperor, and the emperor could use this to separate Zhu Di's father and son. “

Zhu Yunwen wrote a letter in his own hand, handed the letter to Xue Yan, the Shaoqing of Dali Temple, and sent it to the king of Yan, and drafted a proclamation of thousands of words, and printed more than 1,000 sheets, so that Xue Yan went to the Yan army and spread it to the soldiers of the Yan army.

Xue Yan, a native of Ruxiang, Shaanxi, is recorded in the history books as a well-being person, ambitious, very ethical, capable of governance, and eloquent.

Whether the adjectives such as Kang Yi in the front are true or not, Zhu Gaoxian does not know, but eloquence should still be there, otherwise, why did Zhu Yunjiao choose him as a Chinese military official?

At least, Xue Yan is a smart man, after he arrived in Dongchang, he hid the thousands of illegal publications, let alone distribute them to the soldiers of the Yan army, and he didn't even dare to show his face.

Zhu Di did not receive him like he received Li Decheng, although Li Decheng was just a eunuch, and Xue Yan was a scholar anyway, he was high, looked at Xue Yan kneeling on the ground with cold eyes, and asked mercilessly, "What about Li Decheng?" The king heard that after he returned from the king, he was locked up? ”

"This king once heard that the younger generation should respect the subordinates who have served their parents and elders, and treat them as half elders, Li Decheng is the person who served Emperor Taizu, I think back then, Emperor Taizu was very respectful, sure enough, people go to tea and cool, Emperor Taizu is gone, and those who have served him wholeheartedly cannot end up well."

Zhu Di asked sadly, "But what mistake did Li Decheng make?" ”

Xue Yan, who was eloquent, knelt on the ground and trembled, not daring to answer a word, only tremblingly took out the holy decree and handed it to Zhu Di.

Zhu Di took the holy decree and glanced at it, it was a holy decree to pardon the sins of Zhu Di and the soldiers of the Yan army and order them to return to their own country, only saying that in the future, Zhu Di should not interfere in military affairs again, and he was willing to restore the prince forever and be a vassal assistant forever.

After Zhu Di read it, he handed it to Zhu Gaoxian, Zhu Gaoxian glanced at it, the text was crepe, he didn't understand it very well, and threw it to Xue Yan, "What else does the emperor have to say?" ”

Xue Yan didn't know Zhu Gaoxian, he still lowered his head and said in a cold sweat, "The emperor said that if the prince releases his armor in the morning and pays homage to the filial piety tomb, the emperor will withdraw his troops at night." ”

Zhu Di laughed angrily, Zhu Gaoxian was afraid that his father would be angry, so he learned his father's tone and said, "I heard that a person who treats others as fools is a fool himself." When the emperor's grandfather was alive, the emperor would not be stupid to this point, it can be seen that those who are close to Zhu are red and those who are close to ink are black, and Confucian scholars such as Fang Xiaoru are really mistaken from the country! ”

Xue Yan trembled and sweated.

The dog came in and saluted Zhu Di, "Lord Wang, General Zhang Yu asked Lord Wang to take a look at the newly sent firearms in the capital, and the ten tractors full of them have pulled a lot of ammunition." ”

Zhu Di glanced at Zhu Gaoxian, and his eyes seemed to say, good son, well done! The ammunition came at the right time. Zhu Gaoxian was frightened by his brain supply, touched his nose, and avoided his father's eyes, he was not a god, could he calculate that Xue Yan would come at this time? Can you just pinch this point?

Xue Yan was naturally invited to inspect the munitions together, and the so-called acceptance was all Zhu Gaoxian's business, and he used his keen eyes to check whether there were quality problems with these ammunition.

In the industrial field, it is not a drawing, a tool, the right material, and the right processing technology to produce batches of qualified parts.

The corresponding means of detection are also very important.

There is a story that during World War II, the military of a certain country required a 100% pass rate for parachutes, how to detect it? The person in charge of the factory who made the parachute was asked to jump from a high altitude with a parachute on his back, that is, to test it with his own life.

If the bullet is not qualified, it is not only a matter of not being able to kill the enemy, but it is also possible to explode the chamber and kill one's own people.

Fortunately, Zhu Gaoxian got a system, and the system gave him a pair of fiery eyes.

Zhu Gaoxian swept it over, picked out the unqualified shells, put them aside, and classified the qualified ones for distribution.

Looking at the tractors he had never seen before, Xue Yan didn't know how these iron lumps worked, but he knew that if these heavy shells were pulled by a horse-drawn cart, a horse-drawn cart might not be able to pull a few boxes, but a tractor could pull one or twenty boxes of shells, which was a very considerable amount.

Zhu Di didn't miss the changing look on Xue Yan's face, he was very proud, and asked the captain of the transport team who came to deliver the arms, "How many arms do you have at home?" ”

The captain glanced at Xue Yan and recognized that this person should be sent by the Southern Army, and said respectfully, "If you go back to the prince's words, Gonggong Ma left a part, saying that he was afraid that the Southern Army would surround our Beiping City again, so if you are prepared, you will send more of them over." Ma Gonggong also asked his subordinates to tell the fourth prince that the production line is very stable now, the workers are skilled, and the efficiency has improved. ”

Zhu Gaoxian had focused on cultivating the knowledge of production efficiency for Ma Sanbao before, telling him that production efficiency could be improved through those means, and at present, their process line was already optimally configured, and efficiency could only be improved by improving the proficiency of operators.

Xue Yan didn't understand these words very well, but the general meaning was understood, and there was no problem at all with the supply of artillery shells in the rear of the Yan army.

Zhu Di said triumphantly, "You go back and tell Guo Zi this time, send another one, it's almost the same." Why do you have so much? Xue Yan, did you say? ”

Xue Yan was sweating profusely and didn't dare to speak.

The next day, Xue Yan said goodbye, Zhu Di ordered someone to send him out of the barracks, before leaving, he said to Xue Yan, "After going back, thank Your Majesty on behalf of this king, Your Majesty is the closest relative of this king, the father of this king is the grandfather of the Son of Heaven, and the father of the Son of Heaven is the brother of this king." This king is a vassal king, and he is extremely rich, so what else is there to gain? The Son of Heaven has always been kind to this king, if it weren't for the traitorous ministers, why would this be the case? ”

He also said: "This king has to do it, everything he does is to save himself, if he can be ordered to stop the army, the king's family is very happy, but if the traitor is still there, the army has not returned, I am afraid that even if the king wants to strike the army, the soldiers of the Yan army will not agree, and ask the emperor to punish the traitorous ministers, scatter the army in the world, the king and his son will ride alone to His Majesty, only His Majesty will order it!" “

After Xue Yan left, Zhu Di began to prepare for the southward expansion.
