If you haven't changed, don't order

The power of the gunboat was so great that the salvo of twelve 32-pound guns was like a landslide and a sea crack, and no boat could withstand a blow from the gunboat, so it left a very deep impression on Li Ji's heart. If the warship can also fight like a gunboat, and the Qin army does not know the worries if it has a warship, a gunboat can hold a river.

His idea Xiong Jing had already imagined, Gong Yin Dao shook his head one after another when he heard this, and Gong Yijian said directly: "This is impossible." ”

"Why not?" Li asked without giving up. "If the warship can fight with cannons......"

"The keel of the war boat is thin, less than three zhang wide, and the force of the recoils of the artillery is enough to break its keel. If it is installed in the bow and stern of the boat, and only one or two cannons are fired before the war, what is the benefit of the war? Gong Yijian said helplessly.

After Xiong Jing proposed that the war boat be equipped with artillery, Gong Yijian experimented with it, and the war boat was a collision operation, and the speed of the collision reached or even exceeded ten knots, and if the cannon was fired at a distance of 400 meters, it would only take 77 seconds for the two sides to collide. Seventy-seven seconds can be fired at most, plus the previously loaded one, you can only fire two shots at most.

The punt was not a sharp-bottomed ship, and the ship itself was so wobbly that even within fifty paces the artillery might not be able to hit the target in a front-facing situation. The Operations Division originally had these data, but they came in a hurry and came in response to the call, and they did not have time to read these materials.

"The sea boat seems to be able to enter the waters?" Zhuang Wudi conceived a complementary scheme.

"Shao Si is ordered, the Chaos-class gunboats are heavy, and the draft is deep, so they can only enter the river, and they must have a tailwind." Xiong Jing knew what Zhuang Wudi meant. "And it is not as flexible and fast as the warship, fighting in the coastal sea, if the warship has cannons, arbitrarily advancing and retreating, the gunboats are also difficult to defeat."

"In this way, we can only build a city and set up artillery to choke the waterway, but ...... "we can't make a boat with a boat, then we can only place artillery on the shore." Speaking of this, people brought a map, and the water system of Chu on the map was clear at a glance.

"Shui also." Pointing to the depressed place to the west of Nanzheng, Li Ji's finger fell on this place. After finishing speaking, he sighed again, "If the Qin people go down the water, it is useless to hold on to this water." The army could land on top of Fuyi and attack Nanzheng. ”

"Wancheng." The second landing point of Li and his finger is Wancheng. "Fan Xiang, Gaoling, Xiangcheng, Daliang, Taoyi, Xiapi. Zhifu Port, Langyu Port, Huaishuikou, Dajiangkou, Zhejiangkou, Panyu, Huguan, "

Facing the map, Li He pointed out all the important waterways, some of which were in the Chu realm, and some of which were in the Wei and Qi regions. Gaoling and Taoyi are in Weidi, Gaoling is on the bank of Rushui, downstream of Xiangcheng; Taoyi is at the junction of Nanji Water and Lotus Water. Rao was like this, he still shook his head and said: "In these more than a dozen places, when you build artillery to defend it, it will take several years." And the land of my Chu country, the rivers inside it are criss-crossed, and the outside is bordered by the sea in the east, if the Qin people attack me by sea, the gunboats are all in the Red Sea Xizhou......"

"Just summon the red one back." Following the long route without hooks, the red turtle bypassed the Nanyang Land at this time and entered the green ocean, perhaps having arrived at the Hera Stone Pillar at the mouth of the Mediterranean Sea. Xiong Jing said that he would be recalled, but in fact, he could not be recalled in two or three years. On the contrary, the seven gunboats stationed in the Red Sea can recall five, "and today the gunboats are also launched." ”

"Of course, five gunboats have been launched this year." Gong Zhijian nodded. "It's a pity that there are no guns."

Sulfur limited the production of gunpowder, and the Chu army suffered greatly. Before Xiong Jing could speak, he said: "Hushang sulfur has been transported to Donghu, and the king of Donghu promised to protect Hushang to Haikou, and he can get 100 tons of sulfur this year." ”

"Good!" Everyone was shocked when they heard this, and this was great news.

"Now there is only a shortage of saltpeter, and it will take time to transport it overseas." Xiong Jing added. 100 tons of sulfur can be mixed with 1,000 tons of gunpowder, but unfortunately the production of saltpeter on the island is not high. "But there is no shortage of gunpowder in wartime."

"If so, will you build a gunboat next year?" Gong Zhijian asked.

"Yes. Add five, ten a year. Xiong Jing agreed without hesitation. The number of gunboats, plus the five that were not launched, made a total of sixteen. If there is really a naval battle with the Qin army, sixteen gunboats are simply not enough.

"How's the boat?" Gong Zhijian asked again. "Last year, when we built a big boat, we only built 30 boats, and this year we only built 50 boats, and I wanted to build ...... next year."

"Cut." The construction of the boat does not occupy the dock and timber of the boat, unlike the gunboat. The gunboats were constantly occupying the docks, and the workers and timber were crowding the boats, one equivalent to two. "Only forty ships were built."

"But there is no money in the Qian Mansion." Gong Yin Dao had a bitter face. "10,000 boats cost 100,000 gold, and now the sea boat wants to build no money, what if so?"

"No money?" Xiong Jing's face was also bitter. After the war with Seleucus, trade shrank sharply. The threat of the Indians is not terrible, the Mauryan Empire is in constant collapse, the divided states and cities that have not been divided are smuggling, and Fahrenheit City cannot be controlled at all. The problem was that the gunboats blockaded the Persian Gulf, and Seleucus, in retaliation, strictly forbade merchants to sell goods from the Chu State.

"The red man shipped the spices to the Mediterranean, and he had money when he returned from the Mediterranean." Xiong Jing can only be so comforted.

"When?" Gong Yin Dao asked very unsympatheticly, and asked Xiong Jing to give him a time.

"It will take two years." Xiong Jing Road. Looking at the maps on several cases, he couldn't help but think: It's too late to mint coins, do you want to issue banknotes?

"Two years?!" Gong Yin Dao stretched out two fingers, incredulous.

"Or reissue bonds." Knowing the financial constraints, he spent more than 200,000 gold from last year to this year, and the first phase of 300,000 gold bonds was basically used up.

"Why don't you take advantage of the Qin people to sue for peace and issue another 100,000 gold bonds." Zhuang Wudi also said.

Because of the delay of the Battle of Fuying, at present, the sea boats of the Chu State plus the Shao Si Ming class built by Zhuyue are only more than 110 ships, and the transportation tonnage is only more than 42,000 tons, which is far from enough.

"It takes a year to build a sea boat, but in fact it can be June. If the big chapter is dry, day and night, March can also.

"Now there are only more than 100,000 mansion chapters, plus the wood dismantled by the palace, there are only more than 170 sea boats that can be built. More than 100,000 large chapters, many new felling, next year to build 100 boats to build a boat yard will be stopped. "The original plan was 50 ships a year, but now it has soared to 100 ships, and the bus team pointed out the current difficulties." The minister thought that it would be enough to build fifty ships a year, and although the construction was slow, the boat-building yard would not be stopped, and the big chapter would not be unsuccessful. ”

The Tao Tao launched 12 ships this year, 25 ships next year, two years at the same time to build docks, equipment, training workers, the third year launched 30 ships can meet the grain transportation of 10 million stone (including the volume of 3 million stone of Qi Chu Zhouji), the fourth year if the number of ships launched reaches 50, the sixth year can transport 20 million stones.
