"The large counterweight trencher, that is, the Xiangyang cannon, is the siege weapon of the Mongolian Empire civilization, requires 200,000 points."

Chu Tian saw the drawings of the large trencher that the Mongolian army often used.

This kind of catapult battles in Yumen Pass and Luntai City were in great power, causing great damage to the Han army's city, and the fierce general Wang Yanzhang was killed.

Chu Tian has always been coveting this powerful trencher. After all, this is a trencher used in the 12th century, and is more advanced than the threncher Thunderbolt chariot used in the late Han Dynasty.

Chu Tian is considering how to attack Guanzhong.

In the early Han Dynasty, Zhang Liang, the first counselor, told Liu Bang that Guanzhong had the left and the right and the right and the fertile land was thousands of miles away, with Bashu in the south and Huyuan in the north. It blocked three sides and guarded the princes on one side. One side was the east. Jincheng was a country with a thousand miles away, and Tianfu was the country.

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

To attack Guanzhong, you usually have to pass through two routes: Tongguan (Hangu Pass) and Wuguan.

The majestic Tongguan and Wuguan may be an insurmountable pass, so Chu Tian is looking for a powerful enough siege weapon.

The appearance of Xiangyang ** paper is equivalent to the most classic siege equipment of the Mongolian Empire civilization, and can be exchanged.

Different civilizations have different characteristics, and the difficulty of obtaining some technologies is also different. For example, the cost of Temujin obtaining Xiangyang cannons is lower than that of Chu Tian.

Now, Chu Tian can use points to redeem it directly.

"Things are good things, but unfortunately there are too many points needed. No, all the items here are good things..."

Chu Tian thought he had enough points, but he didn't expect that there were countless valuable props.

There are five hundred special items that can be exchanged for by the lords of the Han Empire alone.

If you want to redeemed it 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 cannons can effectively improve the siege ability of Chu Tian’s army, so Chu Tian reserved Xiangyang** paper in his heart.

Chu Tian has already seen the power of Xiangyang cannon.

"Next... the Fubo Legion expanded some time ago, and the sixth-level shipyard was not enough..."

Chu Tian thought of the issue mentioned to him by the Fubo Legion. At present, Chu Tian’s forces are mainly sixth-level shipyards and cannot build more advanced warships.

So Chutian specifically checks whether there are drawings from high-level shipyards and drawings from large warships that can be redeemed.

Chu Tian's eyes fell on the "Longjiang Treasure Shipyard Construction Drawings", this special drawing.

When Chu Tian saw this name, he seemed to look familiar.

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

Chu Tian thought of a familiar story.

During the reign of Zhu Di, the Emperor Chengzu of the Ming Dynasty, Zheng He once went to the West seven times and once as far as East Africa.

At that time, shipbuilding in the East was at the forefront compared to that in Europe and the Arab world.

That's why Zheng He has the capital to lead a huge fleet, voyages to the West seven times, and promote his national prestige.

Zheng He's fleet can be traced back to the reign of Emperor Hongwu Zhu Yuanzhang.

Zhu Yuanzhang and Chen Youliang launched a massive water battle in Dongting Lake and fought to the death. At that time, Chen Youliang, one of the leaders of the rebel army at the end of the Yuan Dynasty, had a strong naval army, which left a deep impression on Zhu Yuanzhang.

Further forward, we can trace the shipbuilding techniques of the Yuan Dynasty and the Southern Song Dynasty.

Civilization is a lineage, and technology is no exception.

The Longjiang Treasure Shipyard opened a factory to build ships during the reign of Emperor Hongwu Zhu Yuanzhang. Later, most of the treasure ships used by Zheng He to voyage to the West were also built in the Longjiang Treasure Shipyard.

Longjiang Bao Shipyard is a Class 9 shipyard and is already quite high-end, almost the highest-end shipyard in the Eastern Han Dynasty.

A level 9 shipyard should be sufficient for use.

Chu Tian thought about it and found that the Fubo Legion did not have tenth-level warships to be built, so the ninth-level shipyard could already meet the cost of the Fubo Legion in the next ten years.

As for the tenth-level warship, Chu Tian could not imagine what kind of warship was a tenth-level warship.

"By the way, production drawings of advanced warships are also needed."

Shipmakers must have drawings of the ship before they can build the corresponding ship.

The shipyard is just a place to produce warships.

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

"The construction drawings of 1,500 materials for Fu Shipbuilding require 200,000 points. Zheng He Bao Ship (2000-5,000 materials) requires 500,000 points."

Chu Tian was shocked when he saw the drawings of Zheng He's treasure ship.

Unexpectedly, there was Zheng He's treasure ship in the redemption list this time.

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

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

Chu Tian looked at the introduction of Zheng He’s treasure ship.

This treasure ship has a large hull, but it is not a special gunship.

The soldiers of Zheng He's treasure ship can also be equipped with firearms and have certain combat effectiveness. In naval warfare, it is actually a little worse than the later specialized warships.

In the era of Zheng He's treasure ship, ships were not equipped with large bronze cannons, because at that time, water war mainly relied on board battles, collisions, crossbow arrows and muskets, and firearm technology was not yet developed enough.

The purpose of building Zheng He’s treasure ship is more to show off his national prestige.

There is a very interesting thing. When the Fengzhou Feng (equivalent to the later Zheng He treasure ship) in the middle of the Ming Dynasty went on a mission to Ryukyu, the ship was too large and inconvenient to operate. When the fleet arrived at Ryukyu, the sea breeze suddenly disappeared, and the Ryukyu Kingdom could only use more than 50 rowing boats to tow the Fengzhou Fengzhou into the port. Later, when the fleet encountered strong winds, the Fengzhou Fengzhou's masts and rudders were broken. The ship workers suggested that the government use flexible and smaller sea ships, while the government believed that it was a loss of power and insisted on using large ships.

People like Chu Tian who value pragmatism do not care much about showing their national prestige, nor deliberately tribute trade. He would rather colonize than do business with losses. There is no need for kindness in the era when the strong prey on the weak.

Zheng He's treasure ship is a type of lucky ship and one of the peak ships in the era of cold weapons.

Later, the lucky ship was gradually replaced by bird ships in the late Ming and early Qing dynasties, which was equivalent to the Western Carac sailing ships being replaced by Garen ships because firearms were improving.

Therefore, Zheng He Bao Ship is not the best warship in "Lord". The best warship in the Eastern Han Dynasty was the big bird ship, that is, the large bird ship. It uses large-caliber bronze cannons as its main attack method, and the two were 200-300 years apart.

Chu Tian thought of this and specifically checked whether there were construction drawings for the Big Bird Boat.

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

Chu Tian looked again if there were Western Carac sailboats, or even Garen sailboats.

Galen sailboats appeared in Spain in the mid-Ming Dynasty, and Western shipbuilding began to make rapid progress. Like the Big Bird Ship, they were special gunships.

However, Chu Tian did not see Garen Sailboat in the convertible list.

Logically speaking, the construction drawings of the Carac sailboat or Garen sailboat may appear in this national war.

The lords of the Eastern Han Dynasty did not see this special prop, so it is very likely that the Carac sailboat or Garen sailboat appeared in the convertible list of the lords of the Western continent.

The Big Bird Ship and Galen Sailboat must be equipped with bronze cannons to achieve their effect.

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

But he saw a special weapon drawing - the Big Bowl Gun.

"What kind of firearm is this?"

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

【Name】: Big Bowl Gun

【Level】: Bronze Fireware

[Description]: A primitive small cannon, with no sights, short body tube, slow firing rate, short range, and low hit rate. It can be used in the early Ming Dynasty to the early Qing Dynasty and can only be equipped on the lucky ship and the bird ship.

[Specification]: The diameter is three inches and four inches, seven inches long, one inch long, and weighs sixty-three kilograms.

【Effect】: With armor breaking, the injury worsens.

【Points required】: 100,000

【Number of redemption】: Unlimited

The big bowl gun weighs 63 kilograms, and it is not very powerful in the water battle.

This kind of firearm that can be equipped on the Fu Ship is equivalent to an enhanced version of the musket (fire door gun).

The power of the big bowl gun cannot penetrate the ship's board because the real bronze cannon weighs hundreds to thousands of kilograms.

However, during the reign of Emperor Hongwu Zhu Yuanzhang, this weapon was mixed with bows and arrows, and was considered one of the most advanced weapons at the end of the Cold Weapon Age and shined.

In order to strengthen the power of the lucky ship, Chu Tian chose to exchange for this special firearm. In the future, the water battle will not only use crossbow arrows to injure the opponent's sailors and soldiers, but also use the big bowl gun to attack.

"A lucky ship that exchanges 1,500 materials."

After weighing the pros and cons, Chu Tian chose a 1500-food ship smaller than Zheng He's treasure ship.

The size of this warship is already quite large, with a length of about 45 meters to 50 meters. Compared with the 30-meter-long 400-meter-long turtle ship, a 35-meter-long turtle ship, a 1,500-meter-long turtle ship is equivalent to a giant ship.

The drawings of Zheng He's treasure ship are too expensive, and the too large treasure ship lacks maneuver power during water wars, so it will not be turned into a gunship in the future. In the end, it will be a cost-effective problem.

Chu Tian only has 1.9 million points. If you want to exchange Zheng He’s treasure ship, you will need to pay 500,000 points, which is too luxurious for Chu Tian.

Therefore, it is better to save a point.

Chu Tian used a 1,500-material blessed ship to make a transition, and later he tried to get the construction drawings of the Big Bird Ship or Galen Sailboat.

The warships of the Fubo Legion will use 1,500-material Fubo Ship as the flagship, 400-material Fubo Ship to escort, and turtle ships to defend the port.

A 400-quality lucky ship is also essential. Whether it is used for fire attack or considering maneuver power, a batch of smaller ships is required.

The larger the size of the lucky ship, the higher the cost.

Chu Tian redeemed 4 drawings in total: Xiangyang cannon, which consumed 200,000 points; Dawankou gun, which consumed 100,000 points; Longjiang Treasure Shipyard (Nine-level Shipyard), which consumed 300,000 points; 1,500 materials and lucky ships, which consumed 200,000 points.

The four drawings consumed Chu Tian’s total 800,000 points.

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

"It's too expensive, things are good things, and nothing can be missing. Unfortunately, the points consume too much..."
