The next day, when Sun Xiangfu went to the Qin Mansion for a trip, he learned what happened in Chang'an City yesterday, and Li Shimin asked him to announce that there was a reason for yesterday's play, so that those who were ready to launch a coup d'état would gather before this point in time and assign tasks, so their whereabouts and gathering points were discovered by Li Shimin's secret guards, and then, before the play, they were easily surrounded and annihilated.

"Your Majesty's every move has a deep meaning, and those chaotic ministers and thieves can't fight Your Majesty." Qin Qiong roughly told Sun Xiangfu what happened, and finally concluded.

"When you say that, I think Your Majesty is omnipotent." Sun Xiangfu said a little depressed, in this kind of big matter, he can only be an inconsequential supporting role after all, and he can only know part of the whole thing from Qin Qiong afterwards, which fully shows the emperor's distrust of him.

"Not necessarily, Liang Shidu in Shuozhou and Feng Ang in Lingnan are problems that are difficult for His Majesty to solve, these two are cautious, and it is difficult for even the secret guards to infiltrate them." Qin Qiong shook his head when he heard this.

For some things, he can choose to say to Sun Xiangfu, in addition to Liang Shidu, who has long rebelled, the most powerful thing in the recent dynasty is the rebellion of the Lingnan chieftain Feng An, Feng Ang lives in Lingnan, and its jurisdiction has twelve states, thousands of miles from east to west, north and south, with 100,000 armor, all of them are Yimin and Fangmin, Li Shimin's people can mix in, it is strange, his magnitude, but a few Wang Junkuo can not compare.

"Lingnan Feng Ang rebelled?" Among the many film and television dramas that Sun Xiangfu has watched, there is really no story of Li Shimin fighting with anyone in Lingnan, he was preparing to go to Lingnan recently, and he was a little surprised when he received the news.

"It's just a rumor, it may not be credible, Feng Ang is a well-known person in Lingnan, and His Majesty has sent someone to investigate secretly, hoping that he will not take risks." Qin Qiong sighed.

Feng Ang's rebellion is what Li Shimin does not want to see, at this moment there are many strong enemies in the north of the Tang Dynasty, if you face the Lingnan barbarians, the country may be shaken, so, in history, Li Shimin finally had to follow Wei Zheng's advice, sent people to pacify, later, Feng Ang very honestly sent his son Feng Zhidai into Beijing, not a few years later, he also came to the capital, Li Shimin entertained him very warmly, since then, the land of Lingnan has never been separated from the Central Plains Dynasty, it can be said that Feng Ang has a lot of credit.

Sun Xiangfu didn't know these histories, but he was more optimistic about Lingnan, the Pearl River Delta, but it was one of the most economically developed areas in China in later generations.

"Speaking of Lingnan, the kid is trying to go for a walk recently!"

"Oh? Are you going to Lingnan? Qin Qiong said with some surprise.

"Well, the kid heard from a businessman from the south that there is a kind of rice in Jiaozhi, which can mature in two months from sowing to harvesting, so he wants to introduce it to Datang, Lingnan is close to Jiaozhi, and it is the best supply point for the fleet and one of the best trial planting sites for this new rice species, so this Lingnan kid is bound to go on a trip."

"Rice that grows in two months?" Qin Qiong knew that Sun Xiangfu was proficient in farming, but he was familiar with history and knew that in the pre-Han Dynasty, the Han people once ruled Jiaozhi, and if there was really such a magical rice, it would not have spread to the Central Plains long ago, so he questioned such rumors.

"This matter is very important, and the kid would rather believe it, so he must go."

There is a possibility that the center of the country at that time was the north and the south, which belonged to the boundary of Nanyue, and Emperor Wu of the Han Dynasty could not actually control it.

In addition, due to the lack of cultivation technology, Zhancheng rice was planted in the Han Dynasty, and one acre of land produced one or two stones of rice at most, and the yield was not as good as millet wheat.

However, Sun Xiangfu believes that Zhancheng rice needs to grow in a warm environment, in Guanzhong, it can be planted alternately with other crops in a small part of the irrigated land, in the south of the Yangtze River, or Lingnan, Yazhou, it can be planted for three seasons, and he knows that in the Northern Song Dynasty, Zhancheng rice in the Jiangnan region set a record of more than four stones of rice per mu, that is not millet, it is husked rice.

With it, there was the Jiangnan of the Song Dynasty, the world's foot, with the Ming Dynasty's Hu Guangshu, the world's foot, such a mantra, at that time, with the land of one or two provinces, it was able to feed a population of one or two hundred million, and now, how many people are there in the Tang Dynasty? One or two million is only, and Sun Xiangfu feels that as long as he gives himself a few counties suitable for growing rice, he can almost guarantee the country's food rations.

While chatting, Uncle De came in to report that Yang Shunshui was here, driving a new boat, and was at Qujiangchi Wharf.

"Yigong, let's go and have a look!" Sun Xiangfu took the opportunity to invite.

"Hehe, look at the boat, Hongshen is an expert." Qin Qiong said with a smile, and asked Qin Hu to go to the Zou Guogong Mansion to inform Zhang Gongjin that since he defeated Jieli and entered the Duke of Jueguo from the county duke, he has been leading the troops outside, and he was only recently transferred back by Li Shimin.

After a while, Qin Qiong and Sun Xiangfu came to Qujiangchi Wharf on horseback, and saw a large ship with a much higher side and mast than other passenger ships in the distance.

"Heh, this is the new ship you made made, at least with a load of 3,000 stones!"

Sun Xiangfu smiled and said nothing, three thousand stones are only 180 tons, in later generations, it is simply not worth mentioning, the load of this keel pointed bottom water ship is at least six or seven hundred tons, according to the stone, it should be ten thousand stone ships, but its size does not look as big as other ten thousand stone ships, because its loading position is all below the splint, as the more goods are loaded, its draft will be deeper, and the ship will be more stable.

Now it is not loaded with anything, and the draft is not deep, so the side of the ship looks five or six meters high, but it is about the same as the Wuya battleship of the Tang Navy, which is a three-story ship.

"Heh, this ship is interesting."

I'm watching the whole appearance of the ship from the shore! I saw a dozen horses coming and shouted, this person is Zhang Gongjin.

"Xia Guan has seen Zou Gong." Sun Xiangfu bowed his hand and said.

"You're welcome, tell me about your ship! and what was it made for? Zhang Gong dismounted, handed the reins to the guards who followed, and pointed to the great ship, which was different from all the ships on the river.

"Let's get on the boat and talk while we visit!" Sun Xiangfu made a gesture of please, and the three of them walked along a gangplank put down on the side of the boat and walked towards the boat.

After walking a few steps, Zhang Gongjin found that the ship did not have oar holes, and the impact angle of the bow of the ship was still wrapped in fine iron, and there were two huge wheel-like objects at the back of the boat.

"Zou Gong, the name of this ship is called the water steamer, and it is not pushed by the boatman's oars, and you can see it when you go down to the cabin."

Walking on the plywood, Zhang Gongjin found that in addition to a low lookout room at the tail of the ship, there were only masts and sails on the wide plywood, and the number of masts reached five, and the small side sails were not counted.

Then, walking from the lookout to the inside of the cabin, he found that there was a lot of stuff in the ship, and under the lookout, there were many gear discs made of fine iron, and on both sides of the gear discs, there was actually a cowshed, and four or five bullocks were tied to the cowshed.

"Well, how did the cow get to the boat?"

"Hehe, this is the subtlety of the water steamer, put on these buffaloes, let them pull these stone mill-like gear discs, you can drive the propellers on both sides and bottom of the big ship to rotate, even when there is no wind and water, you can also push the big ship forward."

Hearing this, Zhang Gong was stunned, sailing against the current has always been a problem that the ancients were not easy to solve, the canal in the early Tang Dynasty had just been dug, and the waterway situation was relatively good, but even so, it often took a large number of slender men to pull the boat away, because once the wind and water were against the water, the boat with a larger load could not row at all, and the water steamer pulled by the ox could actually push the ship forward in the case of the wind and water, is it that the load of the ship is not large?

"You water steamer, how much load is it?"

"More than 10,000 stones."

"Wanshi? No way, your ship isn't the size of a Wanshi ship. Zhang Gongjin did not believe it.

"Zou Gong can follow the lower official to the cabin below." Sun Xiangfu smiled, and let Yang Shunshui lead the way in front, although most of the ship was designed by him, but the shipwrights will also make a lot of changes according to the actual situation, what is the specific interior, Sun Xiangfu, who is on the ship for the first time, does not know everything.

"Qi Yu a few adults, there are three floors in the cabin, the top floor is for people, there are more than 30 rooms on the left and right, each room is very loose for two to four people, the lower two floors, is the warehouse, if you load goods such as grain and rice, Wan Shi is not a problem, and there can be more heavy objects such as ironware, as long as the draft is less than the seven CD of the height of the ship's side, there is no problem."

As he spoke, Yang Shunshui led everyone from the corridor of the first floor to the end, Zhang Gongjin and Qin Qiong's eyes swept the rooms on the left and right of the cabin, and found that the space inside was not small, there was a fixed wooden square table in the middle, and the upper and lower bunks were made of wood on both sides, as well as cabinets nailed against the wall of the ship, and four people lived in one room.

"Tut-tut, your ship looks like a cargo ship of five or six thousand stones at most, and the space inside is so large, and the arrangement is reasonable, it is really a treasure ship." Zhang Gongjin praised.

There are more than 30 rooms, which can accommodate more than 100 people, and the warehouse below can hold more than 10,000 stone goods, but it is much more advanced than the standard warships of the Tang Army.

Of course, he still didn't see the whole ship design clearly.

When Yang Shunshui walked to the center of the boat, he pulled the machine expansion on the wall of the ship, and the thick splint actually spread out to both sides, revealing the sky overhead, and then pulled another machine expansion, and the wooden planks in the corridor under his feet also expanded to both sides, and when Yang Shunshui pulled two sliding doors slightly wider than the door of the room to both sides, Zhang Gongjin and Qin Qiong suddenly found that from this position, they only needed to stretch a springboard to connect to the shore, and the gangplank could be stretched on the left and right sides, and there were heavy objects on the boat from the springboard. It can be directly lowered to the warehouse on the second and third floors, and it is also very convenient to pick up the goods from the warehouse.

Of course, what they don't know is that the reason why Yang Shunshui opened the splint on the top of his head is because there is a heavy iron frame on it, on the iron frame, the goods can be lifted with ropes, and the stress points have iron ring pulleys, one person can easily lift hundreds of catties of goods by pulling the rope, and the two warehouses below have carts with wheels, which can easily push the goods to the corner and unload them. Before and after, Sun Xiangfu spent more than 10,000 yuan to build this ship, which is not counting the hidden investment in research and development.
