As the fleet moved, a shadow of a sail appeared in front of it, and it grew larger and larger. To everyone's surprise, the speed of this sea ship was even faster than that of the Changsheng Island Bird Boat.

The ship's side is so low that it looks almost above sea level from a distance. The bow of the boat is sharp and constantly splitting the waves on the sea, and it also uses two tall triangular soft sails, which are blown into an exaggerated arc under the agitation of the sea breeze.

The ship rode the wind and waves and quickly came to the front of the fleet, only to see that the ship was also hung with the naval flag of the blue sun and moon of Changsheng Island. Then this ship is a dhow made by Changsheng Island itself, and there is no doubt that this ship should be launched in the day.

As the ship approached the flotilla, dozens of sailors on board shouted in unison: "Welcome home!" Then the boat turned around and sailed quickly towards the docks of the Dragon King Temple.

From here, a bird boat or sea boat joins the fleet every few days away. When we arrived at the Longwang Temple Pier, it was already crowded.

Tens of thousands of people were on the docks to welcome the return of the long-sailing fleet. The moment the Yuxiu docked, all the people were boiling.

Their patron saint is back, and as long as Zhang Dou is on Changsheng Island, he no longer has to fear the attack of Jiannu.

During this time, Huang Taiji has been staying in Fuzhou, constantly going back and forth to Fuzhou to gather Jurchen armor soldiers. Now it has become a huge barracks, and the Han Eight Banners have been drawn to as many as 10,000 people.

Although Huang Taiji has never attacked Changsheng Island, the strength of almost 20,000 people is almost overwhelming.

The thought of the scene of the 10,000-strong siege of the city makes people shudder. The Liao people had already lost their homes once, and they didn't want the Changsheng Island they had worked so hard to build to be destroyed by Jiannu again.

In the past few days, the Liao people have begun to build the fortifications between the north and south of the Xinkou under the organization of the Changxing Army, and tens of thousands of people in the 20-mile-wide area have been repaired for three months before they are completed, and the three lines of defense are desperately guarding Changsheng Island from the encroachment of Jiannu.

At this time, Changsheng Island was a little relieved, as long as these lines of defense were there, no matter how many Jiannu Changxing troops came, they would have the confidence to hold Changsheng Island.

Zhang Dou got off the boat and was punched in the chest by Sun Yuanhua: "You stinky boy has been gone for two months, you have thrown all the big and small things on Changsheng Island on the old man, do you want to exhaust the old man?" ”

"Uncle Shi can work hard! You're in good health! If you are free one day, you will really get sick! Zhang Dou said with a smile.

Sun Yuanhua has always been very healthy during his busy days on Changsheng Island, but he seems to have aged a lot when he arrived in the capital. Recently, he has been so busy that his feet are almost touching the ground, and he is still much younger. This is the power of the spirit, and the work here has given Sun Yuanhua a second spring.

With the unloading of boxes of gold and silver belongings from the sea ship, Sun Yuanhua went from shock at the beginning to numb at the end. He couldn't close his mouth when he smiled, and he wanted to exchange everything for silver when he was short of money recently.

The merchants paid silver for the grain, the ore for the ore, the craftsmen for rewarding them, and the orphans for raising and educating the orphans.

If he hadn't been careful with his calculations, Changsheng Island would have to default on the payment for the goods last month. Even so, this month's silver Sun Yuanhua still doesn't know where to get it! Now, just a rough count of all kinds of gold, silver, and jewelry adds up to 630,000 taels. With so much silver, many plans can be carried out.

Zhang Dou walked up to Zheng Yiguan and said, "Brother Zheng! Thanks to your help this trip, the two months have also delayed your business. You can tell how much silver you should have, Zhang will never bargain! "The current Zhang Dou can be said to be wealthy, and what can be solved with silver is not a problem.

Zheng Yiguan waved his hand and said: "I will see the outside when I mention the silver, and Zheng is just helping, how can I collect the silver?" Zheng Yiguan shirked it, and finally euphemistically expressed his interest in the artillery made on Changsheng Island.

Zhang Dou gave Zheng Yiguan thirty 3-pounder cannons and five 6-pounder cannons with a wave of his hand. Zheng Yiguan got the artillery and left happily, he didn't know that Changsheng Island could already cast 18-pounder guns, and those 3-pounder and 6-pounder cannons were originally going to be eliminated, and they were just given to Zheng Yiguan as a favor.

Zhang Dou will not be stingy with increasing the strength of his allies, and the main artillery of Changsheng Island in the future will be 9-pounder and 18-pounder guns. Continue to research the next generation of 24-pounder guns and the short-barreled Caron cannon that is invincible in close combat, and the combination of these two guns is the guarantee of the invincible sea of the Immortal Island fleet.

Everyone in the conference hall sat on both sides, and Zhang Dou spoke first. He talked about the gains and losses of the southward trip to Macao, and then talked about the pirates on the South Shark Island and the golden route off the coast of Fujian.

Everyone present had no opinion except that Sun Yuanhua thought that the pirates were not credible and needed to send more personnel from Changsheng Island

Then Sun Hedou talked about the output of the fire gun workshop in the past two months. Thanks to Sun Hedou's efforts, the firecracker workshop on Changsheng Island has been able to produce qualified springs, and the flintlock firecracker can produce thirty pieces a day, and the arquebuses used in the Changxing army can be replaced in a few months.

Moreover, the rifled guns proposed by Zhang Dou have also been manufactured, but the yield is too low, and only about five qualified guns can be produced per month. Although it is difficult to manufacture, it is a machine that kills the enemy on the battlefield. It can easily hit a target from 200 paces away, and can be used as a sniper rifle on the battlefield.

Its disadvantages are also very obvious, the rifling will make the seal of the firearm poor, so when loading, you need to use lead bullets larger than the caliber of the firecracker.

The gunner also had to carry a hammer with him to nail the buckshot into the gun, so it was very cumbersome to load. The damage to the gun pipe is also very large, and if you hit about fifty guns, you have to scrap a gun pipe.

Zhang Dou patted his forehead when he heard this, this was his negligence. Rifled guns need to be paired with Migne bullets, which are the earliest conical bullets.

This buckshot is similar in shape to the bullet head of a modern rifle bullet, but it has a hollow tail and a small piece of cork stuffed inside.

When the Minne bullet is loaded into the gun, the gunpowder will ignite the cork at the moment of fire, and the tail of the buckshot will be stretched out and tightly attached to the wall of the gun, which can play a good role in sealing the gun.

The manufacture of the Minne bomb is not complicated, Zhang Dou understood it as soon as he said Sun Hedou. He didn't care about what he was going to say next, and hurried to the shell workshop to experiment with the Minne.

Seeing that the eldest son ran away regardless of it, Sun Yuanhua smiled awkwardly and took over the conversation. He was also responsible for the water cooling of the inner mold, which made a breakthrough, and now the artillery cast on Changsheng Island was much lighter than ordinary artillery.
