This night, the moon is bright and the stars are sparse, and the Sichuan River is flowing quietly.

Li Weier and Li Yue'er have already fallen asleep, and this time they came out, they were happy to go crazy, traveling and shopping, playing, gambling money, pai gow, mahjong, and the little brother's poker. Reckless drinking, all kinds of local delicacies, some of the food that I have never even heard of, tasted it all over again, enjoyed the food inexhaustibly, happy, and danced a song for everyone on the deck, won bursts of applause, life should be like this, this time I ran out of the right run, even if I went home and was beaten by my father, I recognized it.

The two of them also slept in Zhengxiang, Xiaolan loved to kick the quilt when she slept, showing her long legs at this time, and there was still a trace of saliva at the corner of Xiaoju's coquettish mouth. Xiaomei was snoring a little, while Xiaolan was smirking, talking in her dreams, "Young Master, you are dead" I don't know what kind of dreams this little hoof is having.

The next day, the fleet continued to go up, Fengdu Ghost Town, Zhongxian Shibaozhai, Baidi City, and Zhang Feimiao all stopped to go ashore for a trip and continued to go up the river. After dark, we finally arrived at the most dangerous channel of the Sichuan River, even more dangerous than those terrible reefs on the Three Gorges.

In the middle of the night, it has to pass through the Three Gorges area during the winter dry season, the most dangerous, the water depth is less than three meters. Li Jing didn't dare to sleep, and stared at the channel with the cyborg crew, the squire, and Bai Yu. There is no problem with the shallow draft of the Hurricane No. 1, but the Black Pearl has a draft of 2.8 meters, and it is almost sailing against the highest reef under the water, with only a foot in the middle, because the water surface rises and falls, Li Jing is worried about running aground and hitting the reef.

Before the Three Gorges Reservoir was completed, there were dangers everywhere in the navigation of the Sichuan River, especially the Bayang Gorge and Luomoraine, which were feared. The old shipwright of the Sichuan River said that "it is not as deep as Bayang, and it is not as shallow as Luomoi." ”

Taking advantage of this opportunity, Li Jing asked Bai Yu and Shi Jian to mark the water depth and flow rate and other information on the inland river atlas purchased on the platform provided by Li Jing according to the mapping skills he had taught them, so as to prepare for the development of the Sichuan River waterway.

In the future, the Li family's merchant fleet will enter Sichuan and Yunnan through the tributaries of the Sichuan River, and the Three Gorges route into the Sichuan River is particularly important, which is also the main purpose of Li Jing taking everyone out to play, to explore the upper reaches of the Yangtze River, to open up the route from Wuchang to Chongqing, and to record the hydrological data along the coast.

Sichuan is the land of abundance, rich in products, large in population, and has huge commercial value, Li Jing will later set up a foothold of the Li family in Chongqing, and send personnel to be responsible for business and trade here. There are even plans to build a shipyard in Chongqing to produce shallow-water cargo ships suitable for the Sichuan River and its tributaries.

The Black Pearl piloted, followed by the Hurricane No. 1, the tip of the bottom compartment of the bow of the Black Pearl has tempered bulletproof glass underwater portholes on both sides, and there are high-intensity lights outside, you can clearly see the bottom of the river, as soon as possible There is a lot of sediment, but the large reef can still be seen, so that the fleet finally passed the most difficult route, and at the same time, it also announced that the basic exploration of the waterway from Wuchang to Chongqing was completed. As you sail upstream, the depth of the water will deepen dramatically, and some of the water near Chongqing will be hundreds of meters deep.

At dawn, Li Jing and the captain were drinking hot coffee on the bridge to keep warm, Li Jing had dark circles under his eyes, the Sichuan River channel was already very narrow here, and last night the sword kept using a sextant to mark the latitude and longitude on the map, and it was not far from Chongqing.

At this time, the sound of drumming came from the mountain south of the river, and there was a tall watchtower on the top of the hill, and wolf smoke rose from the nine-story tower. More than ten copper drums are lined up in a row under the watchtower, and the knocking is loud. A small town made of stone and clay by the river. The watchtowers in the small city are dense. Moreover, the bank of the river is a high cliff, and the city wall is built according to the high cliff, and there is a chain bridge connecting another high cliff, which has a gentle slope to the river bank.

Li Jing recognized at a glance that this was a unique building watchtower of the Sichuan ethnic minorities.

Towers are mostly built next to village houses, with a height of between 10 and 30 meters, to defend against enemies and store grain, firewood and grass. The watchtower has four corners, hexagonal and octagonal forms. Some are as high as thirteen or fourteen floors. The building materials are stone flakes and yellow clay. The base of the wall is 13.5 meters deep. It is made of stone flakes.

The inside of the stone wall is perpendicular to the ground, and the outside is slightly inclined from bottom to top. The construction is not based on drawings, hanging lines, and column supports, all with superb skills and experience. The building is solid and durable. Extremely strong, Emperor Qianlong attacked Jinchuan and bombarded it with heavy artillery for many years. Only then did the watchtower be flattened. These buildings are sturdy and almost metamorphosed, and earthquakes like the Wenchuan earthquake did not knock down the watchtowers that remain in the history of western Sichuan.

There are about 4 kinds of watchtower functions, namely, to pass the tower, the beacon tower, the village towers and the home tower.

The key blocks are often built on the cliffs and dangerous roads, or they are blocked by the key points, and there is a role of being a man and a man;

Beacon fires are built on the top of the mountain to convey information;

The walled tower is a war tool built to protect the village or tribe, and generally stands at the head of the village;

Most of the houses are connected to the building, and they are used as storage rooms in peacetime, and can also be used for war in case of war.

The door of all watchtowers is opened in a place of one or two zhang high, there is a single wooden ladder in front of the door, once the enemy comes to attack, as long as you retreat into the watchtower, pull out the stairs, close the door, it is extremely difficult to enter. Moreover, there are arrow holes in the building, which are shot by arrows at a distance, and rolling wood and stones when they are near, which is easy to defend and difficult to attack.

After the chain bridge into the village, close to the watchtower, all are made of pieces of stone. The high ones are more than ten zhang, and the low ones are five or six zhang. The foundation of the bunker is more than a foot wide, and it is generally made of boulders. The watchtower is mostly quadrangular, there are also pentagonal, hexagonal, and the most one watchtower has 13 corners. Although they are all made of sheet stone, the surface of the wall is smooth, the gaps are tight, and the edges and corners are straight, which shows that the architect has superb design ability and craftsmanship.

There are a lot of native soldiers on the wall, these soldiers are not wearing armor, they are all wrapped in their heads, barefoot, carrying large knives that do not look very good in their hands, a few people are holding bows and arrows, and more people are holding spears.

The spear has a hook on its head, unlike a hook scythe, because there is also an iron ring on the other side. See this strange weapon. Li Jing couldn't help but smile, he forgot an important thing.

Li Jing gave an order, all the cyborgs, change into naval uniforms, distribute weapons, and prepare for battle. Li Jing immediately opened the light curtain, and the customer service sister appeared, "Host, the situation is more urgent, I have scanned a total of 12,000 soldiers on both sides of the river, although they are poorly equipped and have no armor and firearms, but these barbarian soldiers wearing a small amount of leather armor are very fierce. ”

"I need to buy some weapons, the more lethal the better, what can I sell with the current tech tree situation"

"Don't think about 98K and other hosts, I checked, the biggest lethal weapon you can buy at the moment is the lifting gun, the advance explanation is the early lifting gun, the early lifting gun of the breech charge, not the late lifting gun of the breech firing metal fixed loading bullets produced by the modern arsenal in the Westernization Movement."

"Show me the data, I remember that this thing was in the Ming Dynasty, it's not high-end, it's a large caliber, loaded with shotguns, a dozen large pieces, known as the year when the Crow War, someone hid in the alley, and put down eleven patrolling British lobster soldiers with one shot."

At this time, the morning fog on the river dissipated, and in the distant telescope, there was a stone town on the opposite side of the stone town in Jiangbei. And both Stone Towns have docks and plenty of paddle boats. Jiangbei Stone Town is also densely packed with watchtowers. But the difference is that there is a large flat land outside the city in Jiangbei, which seems to be a military camp and a school field. There are a lot of military tents inside, and there are also wooden generals' platforms. A large flag fluttered on a high flagpole, and in the middle it was written "Stone Pillar Xuanwei Si Qin", and at this time, countless soldiers poured out of the camp tent. Dense I don't know how many.

Li Jing found that there seemed to be a thin black line in the water, so he quickly adjusted the focus and looked carefully. "Horse, play with Lao Tzu across the river."
