All-people naval warfare: from patrol boats to aircraft carrier fleets

Besides, don't look at the engine currently equipped on the Yanhuang is an old-fashioned diesel engine, the power is not large, and the horsepower is insufficient, but due to the rules of the Great Navigation World, the starting speed is quite fast, and it can be started almost in just 3 minutes.

This made Ye Bai more sure, even if he encountered a pirate warship again, it would only take a few minutes to change from a stationary state to a full-speed state, and he could decide for himself whether to fight or go.

Intense white beams of light vanished from the sea, and the entire surrounding sea was once again plunged into darkness, with only sporadic lights revealing from some of the important cabins on the Yan Huang.

Standing on the foredeck, looking at the fallen iron box that was salvaged, Ye Bai did not hesitate at all, and directly chose to open it.

[Congratulations to the player for successfully sinking the pirate gunship, opening the enemy ship and dropping the iron box, and obtaining 200 rounds of 102mm caliber shells, 600L of diesel, and 20,000 yuan in money].

Strictly speaking, the drop materials in the iron box are not very large, only 3 items, but the amount is quite large.

200 rounds of 102mm caliber shells just replenished the previous combat consumption of the two twin-mounted 102mm naval guns in the front and rear, which can be regarded as saving a little money.

Not to mention the fuel, the Yan Huang has to continue sailing on the sea, and it needs a lot of fuel, although the fuel tank on the Yan Huang is almost full of 22 tons of diesel, but it can be replenished, who doesn't want it, not to mention that the system is so generous this time, rewarding half a ton of diesel.

As for the final monetary reward, it can be regarded as beyond the ordinary, Ye Bai has also opened an iron box before, but he has never obtained so much money, a full 20,000 ah, this time Ye Bai is satisfied, although there are no basic materials such as rice, vegetables, and fresh water, but obviously money is more important, as long as there is enough money, those basic materials are not a matter at all.

Ye Bai's eyes rolled, and he thought of how to spend this money, not to mention anything else, at least to buy another 4SD-19/32 diesel engine, so that even if the power system of the Yanhuang is perfect, it can maintain a maximum speed of 12 knots.

As soon as he turned around and was about to go to the power compartment to add another 4SD-19/32 diesel engine to the Yanhuang, a prompt message came from the system again.

[System Prompt: If the player is detected to be the first player to sink a pirate gunship, the system will be triggered to hide the achievement and obtain the achievement reward: a set of ecological cycle system.] 】

Ye Bai was directly stunned in place, if he remembered correctly, when he sank the pirate patrol ship before, he had already completed the achievement of sinking the first pirate battleship and received a reward, which made the fire system of the Yanhuang greatly upgraded, and there was a battle to successfully sink the pirate gunship.

But he really didn't expect that after sinking the pirate gunship, he would be able to trigger the hidden achievement again and get the reward of the system, if so, does that mean that the first time to sink a destroyer, cruiser, battleship or even an aircraft carrier can also achieve the hidden achievement of the system?

Ye Bai didn't know how the system was set up, but at least people could have a little more expectations, not to mention that now that the rewards have been received, the rest will be talked about later.

Ye Bai frowned, a little unsure what the hidden achievement reward meant this time, a set of ecological circulation system, what the hell is this?

Somewhat unclear, Ye Bai opened the system panel and checked what this so-called ecological circulation system was.

[Ecological circulation system: Placed in the cabin of the warship, an independent natural and artificial ecological circulation system can be formed in the internal space of the cabin, which requires a large amount of energy. 】

The system really gave information about this reward, but Ye Bai still saw it a little foggy, he was not a scientist, where could he figure out these things.

Just when Ye Bai was frowning and thinking hard, a flash of inspiration suddenly flashed in his mind, and he hurriedly walked to the logistics cabin, and pushed open the door of the cabin, and the huge internal space inside was in total darkness.

This logistics cabin is strengthened by space spars, on the surface, it looks like a normal cabin, only a few dozen square meters in size, but in fact, inside the cabin, the area is quite large, Ye Bai has no concept of space and area, but according to the crew, the area of this logistics cabin is several thousand acres.

With such a large area, in the absence of a lighting system, it is naturally pitch black, standing in the dark cabin, Ye Bai opened the system panel and placed the ecological circulation system he had just obtained in the logistics cabin.

With Ye Bai's choice confirmed, the system has begun to use its own power to improve the Yanhuang, and the time is not long, and the adjustment will be completed soon.

As soon as the system was adjusted, the pitch-black logistics cabin underwent great changes, first of all, there was light in the cabin, not normal sunlight, but a faint silver-white moonlight.

With the illumination of the moonlight, the darkness in the cabin was dispelled, so that Ye Bai could clearly see the next changes in the cabin.

The original wooden floor has been covered with a large amount of earth, as if standing on land, and in the distance large trees have risen from the ground, mountains, hills, forests, and even rivers have appeared, and the most gratifying thing is that a huge freshwater lake has been created.

Ye Bai looked at all this in front of him with some dumbfounded, the round moon hanging in the sky, and everything in the cabin, all seemed so unreal.

It can be said that after being adjusted by the system, Ye Bai felt that he was not on the sea at all, nor was he in a certain cabin of a warship, but returned to a certain piece of land in his previous life.

Under the illumination of the moon, Ye Bai even found the existence of some small animals, such as mice, bees, birds, etc., although there are no large animals, but these small animals have further improved the ecological environment in this space.

At this moment, Ye Bai finally understood what kind of role the ecological circulation system rewarded by the system had, and he dared to recreate an ecological system in this cabin, so that his previous idea of building this cabin into a logistics base could be fully realized.

After obtaining a space spar last time to transform this cabin, Ye Bai thought about using the huge space to build a logistics base, so that the Yanhuang could be self-sufficient.

But then Ye Bai realized that he had thought things too simply, although there were seeds for all kinds of food for sale in the system mall, and even fertile soil, but the problem was that if you want to grow these things, you can't just have water and soil, and just one light condition broke Ye Bai's plan.
