Li Yaowei's return to Chang'an caused some sensation in the literati circle of Chang'an City. The poems and essays of Li Yaowei's family some time ago, plus several poems by Xie Yunfei, Xu Qiuping, and Qian Ersheng, were compiled and published by Mo Jiang and Xu Wenmin under the name of "Wen Xianju Collection".

The name of Wen Xianju has gradually emerged in Chang'an.

Li Yaowei didn't care about the outside world, but stayed in the study all day long, compiling books with Du Manwan, Xiao Qin, and Su Yue, and compiling an encyclopedic book based on the knowledge that Li Yaowei mastered.

"From the land, to the sea, to the heavens." Li Yaowei determined the order of the books and formulated the catalogue index of the books, "No, Your Majesty wants me to write about the South China Sea first, then write about the sea first." ”

"Can you understand what I'm drawing?" Li Yaowei stopped his pen and held his chin to study his work.

Several women laughed, and Xiaoxuan said with a smile: "Xianggong, I haven't painted anything, and I am better than you." ”

"......" Li Yaowei reluctantly dropped his pen, he really couldn't draw, and he couldn't master the lines and proportions, "Manwan, you can draw." ”

"I thought there was nothing that Xianggong was not good at, but it turned out that there were still some." Su Yue said with a smile.

"It's too much."

"Sister Zijing's painting is so beautiful." Xiao Xuan sincerely admired. Li Yaowei couldn't help but be fascinated when he looked at it, and sighed in his heart: The ancient otaku and otaku were really proficient in piano, chess, calligraphy and painting.

"Xianggong, do you say that anyone believes these things?" Fifth Yao asked, "I mean those ordinary people. ”

Li Yaoyu pondered for a moment, a little uncertain, "If you just look at the content, it looks like I made it up." But based on my name, I think I'll still believe it. ”

"I'm afraid that the emperor won't believe you and think that you are making things up, and if you are accused of bullying the king, it will be troublesome."

Li Yaoyu shook his head, "If he wants to kill me, he doesn't need to be charged at all." Let's start with the first part, about the size of the world we live in, and some things about the oceans. ”

Fifth Yao thought of an idea, "That globe, we can give it to Your Majesty, maybe it will be easier for him to believe it." ”

"Uh-huh." Li Yaoyu nodded, "Did we bring it back?" ”

"Bring it, it's still Xiaoxuan who wants to bring it."

……

A few days later, Li Yaoyu and Fifth Yao flew into the palace with Xie Yun and presented the compiled books and globes to Li Yuan.

"Where we live is round?" Li Yuan was also incredulous.

"Yes, that's what I heard from a couple of navigators who sailed forward in a boat and returned to the starting point after a few years."

Li Yaowei made up nonsense, he didn't dare to say that he knew, if Li Yuan asked him how he knew, he wouldn't be able to answer, he could only say that he had heard about it.

Li Yuan's eyes were sharp, "Where are they?" ”

"Deceased."

Li Yuan didn't speak, quickly flipped through the book, and then picked up the globe and looked left and right, the silent atmosphere was a little scary, but Li Yaoyu had experienced it, and Wu Yao's psychological quality was excellent, so he was not afraid.

On the contrary, it was Xie Yunfei, who saw the supreme emperor for the first time, and encountered this strange silence again, his legs were trembling.

"What you want, I'm ready." Li Yuan broke the silence and said in a low voice.

"Your Majesty, please find an open place."

……

Walking out of the city gate on the north side of the palace, Li Yaowei couldn't help but glance at the words on the city gate - Xuanwu Gate, but there was no rendering of blood, and there was no sense of vicissitudes of history.

Li Yaojian poured saltpeter powder, sulfur, and charcoal powder into a large jar in proportion, threw in some stones and iron sheets, loaded the pre-prepared leads, sealed the mouth, and then let people carry them into the woods.

Returning to the city wall, he stood next to Li Yuan, "Your Majesty, please stand behind the crowd and cover your ears." ”

A little eunuch lit the lead. Li Yaowei looked at it a little nervously, for fear that something would go wrong.

But God didn't joke with Li Yaoji, the violent explosion scared Li Yuan on the city wall almost fell, which made Li Yaoji's heart tremble, grandma's, if he was scared out, I would die.

Li Yuan didn't care about this, but couldn't help laughing, "Okay, you Li Yaoji, if this thing explodes in the enemy's army, it will definitely be killed and wounded, hahahaha." ”

In the mountains and forests outside the city, the explosion site was surrounded by gunpowder that had been burned black, dust was flying, several trees were broken off at the waist, the bark was peeled off by the air waves of the bomb, and the iron pieces that Li Yaowei put into the bomb were embedded in the trunk of the tree.

Whether it was Li Yuan or several court ministers, they were all shocked when they saw this scene.

"Father."

This forest is not far from Hongyi Palace, and Li Shimin's family was shocked by the explosion and brought it out to check.

"Nothing." Li Yuan smiled and said, "Let's take a look at the treasure made by Li Yaoji." ”

Li Shimin was stunned, "Baby? ”

"King Qin, please take a look." Li Yaowei arched his hand, asked people to make a bomb again, and then the group climbed the city tower and waited for the eunuch to light the fuse.

"Bang!"

The loud explosions, the huge fires, the violent air waves, and the terrifying explosion scenes stunned the well-informed Li Shimin, who was fighting in all directions.

"This ...... What is it? ”

Li Yaowei explained: "This is gunpowder, put gunpowder in a sealed utensil or the like, and after igniting it, it can explode, this is a bomb." ”

Li Yuan said with a smile: "If this bomb is thrown into the Turkic array, within half an hour, the Turkic army will be wiped out. ”

"But how do you get into their ranks? Do you use catapults? ”

Li Yaowei took over the question, "I currently think of several uses, first, the current experiment is to use a jar, when fighting, use bronze to cast into a ball, use a catapult to throw into the enemy's formation, when it explodes, the bronze piece is enough to pierce the enemy's stomach." ”

"Second, bury them in the ground, estimate the time of the Turkic march and ignite it, and when they arrive, it will explode."

"Thirdly, for these two purposes, the bomb can be made very large, and the third use is to make it smaller, tie it to an arrow, and shoot it into the rear of the enemy."

"Wonderful! Haha, Li Yaoji, I didn't expect you to know so much about the war, haha, okay, just do it. Li Yuan laughed, some old people became vigorous at this moment, looking at the north, their eyes were as sharp as a sword, "Conquering the Turks is just around the corner!" ”

Whether it is Li Shimin, the ministers of the court, or Li Yaoji, Fifth Yao, and Xie Yunfei, they are all a little excited.

"Your Majesty." Li Yaojian arched his hand and said, "The power of this bomb is not only that, after the gunpowder burns, the ashes and smell left behind can easily burn the skin and eyes, and if you inhale a large amount, it will also damage the internal organs." ”

"So terrible?"

"Yes."

"Hahahaha." Li Yuan raised his head and laughed, "That's right, Li Yaoji, you have made a great contribution this time." ”

Li Yuan was happy, not only did he exempt Li Yaowei from his last sin and abolish the punishment he gave last time, but he also was crowned as a special jin, a second-grade literary and prose official, and rewarded a lot of things, even Xie Yunfei, who went to play soy sauce with him, got a treasure.
