Chapter 736

"The large counterweight type stone throwing machine, that is, the Xiangyang gun, is a sharp weapon of the Mongolian Empire civilization. It needs 200000 points."

Chu Tian saw the drawings of the large stone throwing machine often used by the Mongolian army.

This kind of throwing stone machine, in the Yumenguan war, Luntai city war, caused great damage to the Han Army's city, Wang Yanzhang was killed.

Chutian has always coveted this powerful catapult. After all, it was used in the 12th century, which was more advanced than the thunderbolt car used in the late Han Dynasty.

Chu Tian is considering how to attack Guanzhong.

At the beginning of the Han Dynasty, Zhang Liang, the first strategist, told Liu Bang that in the central part of the Han Dynasty, the left side of the central part of the pass was a letter from the left side, and the right side was on the long Shu side. There were thousands of miles of fertile fields. In the south part, there was the Rao of Bashu and the benefit of Huyuan in the north side. The golden city is a land of abundance.

It can be seen that Guanzhong is easy to defend but difficult to attack.

To attack Guanzhong, we usually go through Tongguan (Hangu pass) and Wuguan (Wuguan pass).

The majestic Tongguan pass and Wuguan pass may be insurmountable, so Chu Tian is looking for powerful weapons to attack the city.

Xiangyang paper appeared, equivalent to the most classic siege equipment of Mongolian Empire civilization, which can be exchanged.

Different civilizations have different characteristics, and the difficulty of acquiring some technologies is also different. For example, the cost of getting Xiangyang cannon by Tiemuzhen is lower than that of Chutian.

Now, truking can use points to exchange directly.

"Things are good things, but they need too many points. No, all the things here are good things... "

Chutian thought his points were enough, but he didn't expect that there were so many valuable props.

There are 500 kinds of special items that the Lord of the Han Empire can exchange.

If you want to exchange them all, you may need tens of millions of points, or even hundreds of millions of points.

Chu Tian's total points are about 1.9 million.

Xiangyang gun can effectively improve the attack ability of Chu Tian army, so Chu Tian ordered Xiangyang paper in his heart.

Chu Tian has seen the power of Xiangyang cannon.

"Next The vobo regiment expanded a while ago, and the level 6 shipyards were not enough to use... "

Chu Tian thought of the problems mentioned to him by the Fubo army. At present, Chutian's forces are mainly level 6 shipyards, unable to build more advanced warships.

Therefore, Chutian specially checks whether there are drawings of advanced shipyards and large warships that can be exchanged.

Chu Tian's sight falls on the special drawing of "longjiangbao shipyard".

Chu Tian seems to be familiar with the name.

"Zheng He's voyages to the West..."

Chu Tian thought of a familiar story.

During the reign of Zhu Di, Emperor Chengzu of the Ming Dynasty, Zheng He once made seven voyages to the west, once as far as East Africa.

At that time, compared with Europe and the Arab world, Oriental shipbuilding was in the forefront.

Therefore, Zheng He had the capital to lead a large fleet of ships to the West seven times to publicize the national prestige.

Zheng He's fleet can be traced back to the period of emperor Hongwu and Zhu Yuanzhang.

Zhu Yuanzhang and Chen Youliang launched a large-scale water battle in Dongting Lake. At that time, Chen Youliang, one of the leaders of the uprising army at the end of the Yuan Dynasty, had a strong water army, which left a deep impression on Zhu Yuanzhang.

The technique of shipbuilding in Song Dynasty and Yuan Dynasty should be traced back.

Civilization comes down in one continuous line, and technology is no exception.

Longjiangbao shipyard was built during the reign of emperor Hongwu and Zhu Yuanzhang. Most of the treasure ships used by Zheng He in his voyages to the West were also built in Longjiang treasure shipyard.

Longjiangbao shipyard belongs to the ninth class shipyard, which is already quite advanced. It is almost the most advanced shipyard in the Eastern Han Dynasty.

Class 9 shipyards should be enough.

Chu Tian thought about it, and the Fubo army didn't have ten level warships to build, so the nine level shipyards could meet the needs of the Fubo army in the next ten years.

As for the ten step warship, Chu Tian could not imagine what kind of warship was.

"By the way, production drawings of high-level warships are also needed."

Shipbuilders need drawings of ships to build the corresponding ships.

A shipyard is just a place to make warships.

Chu Tian glanced at the list of convertible items and found the construction drawings of the warship that could be exchanged.

"1500 material Fu ship construction drawings, need 200000 points. Zheng Hebao ship (2000-5000 materials) needs 500000 points. "

Chu Tian was shocked to see the drawings of Zheng He's treasure ship.

I didn't expect that there was Zheng He's treasure ship in the exchange list.

However, Zheng He's treasure ship was originally one of the achievements of the Eastern Han Dynasty civilization, so there is no exception to Zheng He's treasure ship.

"Do you want to exchange Zheng He's treasure ship?"

Chu Tian took a look at the introduction of Zheng He's treasure ship.

This treasure ship has a large hull, but it is not a specialized gun ship.

The soldiers of Zheng He's treasure ship can also be equipped with firearms, which has certain combat effectiveness. In the naval battle, compared with the later specialized warships, it is still a little less interesting.In the era of Zheng He's treasure ship, the ships were not equipped with large bronze guns, because at that time, water warfare mainly relied on the fight of the side, collision, crossbow and firearm, and the firearm technology was not developed enough.

The purpose of building Zheng He's treasure ship was to show off the national prestige.

There is a very interesting thing. In the middle of the Ming Dynasty, when the ship was sent to Ryukyu, it was too big to operate. When the fleet arrived at Ryukyu, the sea breeze suddenly disappeared, and the Ryukyu state could only use more than 50 rowing boats to drag the closed boats into the port. Later on the return journey, the fleet encountered strong winds, and the mast and rudder of the boat were broken. The boatman suggested that the government should use small and flexible sea going vessels, while the government insisted on using large ships because of the loss of natural prestige.

Chu Tian, who attached great importance to pragmatism, did not care much about showing national prestige, nor did he deliberately engage in tributary trade. He would rather go to colonize than do a loss making business. In the age of the jungle, there is no need for kindness.

Zheng He's treasure ship is a kind of Fu ship and one of the top ships in the cold weapon era.

Later, in the late Ming and early Qing Dynasty, Fu boat was gradually replaced by bird boat, which was equivalent to the Western karaoke sailing boat being replaced by Galen ship because of the progress of firearms.

Therefore, the treasure ship of Zheng He is not the best warship in the Lord. The best warship in the Eastern Han Dynasty is the big bird ship, that is, the large bird ship. The bronze gun with large caliber is the main attack means. The difference between the two is 200-300 years.

Chu Tian thought of this place to check whether there were construction drawings of the big bird boat.

However, Chu Tian did not see the big bird boats that began to be active in the southeast coast at the turn of the Ming and Qing Dynasties.

Chu Tian looked again to see if there were Western Caracas or even Galen sailboats.

Galen appeared in Spain in the middle of the Ming Dynasty, and the Western shipbuilding began to advance rapidly. Like the bird boat, it was a specialized gun ship.

However, Chu Tian didn't see Galen in the convertible list.

It is reasonable to say that the construction drawings of karake or Galen might appear in the national war.

The Lords in the Eastern Han Dynasty didn't see this kind of special props, so it is very likely that the karake or Galen sailboats appeared in the convertible list of the Lords in the western mainland.

The big bird boat and Galen yacht must be equipped with bronze artillery to give full play to their effect.

Chu Tian did not see any bronze artillery that could be exchanged.

But he saw a special weapon drawing - big bowl mouth gun.

"What kind of firearm is this?"

Chu Tian didn't know much about the early firearms, so he took a look at the names and introductions.

[name]

[grade]: Bronze firearm

[description]: a kind of primitive small gun with no aiming device, short barrel, slow firing rate, short range and low hit rate. It was used from the early Ming Dynasty to the early Qing Dynasty, and can only be equipped on the Fu ship and bird boat.

Specification: the caliber is 3.4.7, the length is 1 foot and the weight is 63 Jin.

[effect]: with the effect of breaking armor and aggravating injury.

[required points]: 100000

[exchangeable times]: unlimited

the big bowl mouth spear weighs 63 Jin, and its power is not huge in the water war.

This kind of firearm, which can be equipped on a lucky ship, is equivalent to a strengthened version of the firearm.

The power of the big bowl mouth blunderbuss can't break through the ship's board, because the real bronze gun weighs from hundreds to thousands of Jin.

However, during the reign of emperor Hongwu and Zhu Yuanzhang, this weapon was mixed with bows and arrows, which was regarded as one of the most advanced weapons at the end of the cold weapon era.

In order to strengthen the power of the Fu ship, Chu Tian still chose to exchange this special kind of firearm. Later, in the water war, not only the sailors and soldiers of the other side were wounded with crossbows, but also the big bowl mouth blunders were used to attack.

"Fortune ship for 1500 materials."

On balance, Chutian chose the 1500 Caifu ship which was smaller than Zheng He's treasure ship.

The size of this kind of warship is already quite large, with a length of about 45 meters to 50 meters. Compared with the current 30 meter long 400 material Fu ship and 35 meter turtle ship, the 1500 material Fu ship is equivalent to a giant ship.

The drawings of Zheng He's treasure ship were too expensive, and the too large treasure ship lacked power in the water war, so it could not be turned into a gun ship in the future. Finally, it was a cost-effective problem.

Chutian has only 1.9 million points. If you want to change Zheng He's treasure ship, you need to pay 500000 points. For Chutian, it's too luxurious.

So, it's better to save an integral.

Chu Tian made the transition with a 1500 gauge Fu boat, and later tried to get the construction drawings of the big bird boat or Galen sailing boat.

The vobo army's warships will take 1500 ships as their flagship, 400 ships to protect them, and turtle ships to defend the port.

No matter it is used for fire attack or considering power, a batch of smaller ships are needed.

The bigger the size of Fu Chuan, the higher the cost.

Chutian exchanged four drawings in total: Xiangyang cannon consumed 200000 points; daguankou gun consumed 100000 points; longjiangbao shipyard (Grade 9 shipyard) consumed 300000 points; 1500 Liaofu ships consumed 200000 points.The four drawings consumed 800 thousand points of Chutian in total.

Chu Tian got three things, only 1.1 million points left.

"It's too expensive. Everything is good. There is nothing to be short of. Unfortunately, too much points are consumed... "

Chu Tian felt a pain in his flesh. Chu Tian could not exchange these four drawings, otherwise he did not know whether he would have the opportunity to exchange these valuable drawings without market in the future.
