――――System prompt: Congratulations on completing the task of encircling and suppressing pirates, successfully exterminating the pirate forces entrenched in Xiyu Island, Giant Fire Island, and Black Rock Island, rewarding your camp with 3,000 prestige, and the remaining task rewards, please find Huiji County Taishou Xu Gui to receive. (Note: When the prestige of the faction reaches the standard, you can receive relevant tasks and obtain the qualification to purchase special items, and when you reach a certain height, you will be rewarded by the system forces and obtain official positions)

As soon as he walked out of the administrative center, he received this system prompt, and the prestige reward of the three thousand camps surprised him, and it also showed the difficulty of exterminating the three groups of pirates from the side, and it is not surprising that there can be such a rich basic reward.

The rest of the reward, it doesn't matter if you slow down, it should be that he can't run.

The entire territory of Blackstone Island is more than 1,000 square kilometers, which is twice the size of Xiyu Island and Juhuo Island combined.

The area of the island is relatively flat, there are not too many mountains and rivers, but the land is relatively barren, the grain production is slightly low, not suitable for growing ordinary crops, it is worth mentioning that the black stone island is rich in mineral veins, although it does not reach the density of Xiyu Island, but it is definitely above the level.

Under the leadership of Li Qi, Ye Feng rushed to the origin of Black Stone Wood and got a lot of information about Black Stone Island from Li Qi, the origin of Black Stone Wood is a relatively special place......

Twenty miles north of Blackstone Town, there is a huge lake, and there is a piece of land in the middle of the lake, which is overgrown with that kind of pitch-black wood, which is the Black Stone Wood, and when he first learned about it, Ye Feng was also amazed.

The two boarded a boat and sailed to land in the middle of the lake.

Seeing that Ye Feng seemed to be a little puzzled, Li Qi explained with a smile: "Lord, you may not know that the Black Stone Wood must be there to grow, and some people have tried to plant the seeds of the Black Stone Wood in other places, but they can't survive at all......

Hearing this, Ye Feng's frowning brows gradually relaxed, this must be a systematic check and balance, he had also heard of this kind of thing in his previous life, such as a certain kind of precious wood, which only grows in a certain area.

Soon after, the two of them landed on the 'island within an island', which was much larger than he had expected, with grayish-brown dirt beneath his feet, and a special lumberyard nearby, where many lumberjacks were at work cutting down the inky black stone wood.

Li Qi beckoned to a middle-aged man working in the lumber yard: "Liu Gong, come here, this is our lord!" ”

Liu Gong put down the axe in his hand and walked over with a smile, this is a special lumberjack, who came to Ye Feng and rubbed his hands with some restraint: "Lao Liu, I don't know anything else, he is a big boss, but he has been here for three or four years, if the lord wants to know about the black stone wood, he will find the right one to find my old Liu." ”

It just so happened that Ye Feng also wanted to know about this aspect, so he smiled and said: "I don't know anything about black stone wood, and I bother Liu Gong to help me solve my doubts, such as the growth cycle and a series of problems." ”

Liu Gong replied fluently: "This area can grow up to 50,000 black stone trees, a black stone wood from the sowing of seeds, it takes a month to grow into nine grades, and a batch of seeds will be produced, and then every month passes, it can rise a grade, that is to say, the black stone wood is completely mature, to reach the five-grade level, it takes five months." ”

……

When leaving, Ye Feng was a little entangled......

When did the black stone wood start to be felled?

This is a very critical question, there are many options for him to choose, five to nine grades can be, the higher the grade, the longer the growth cycle, if the nine grades are cut down, without taking into account other factors, then the output of black stone wood can reach 50,000 units per month, which is a very terrible number.

In the case of five products, the average output is 10,000 units per month.

At this stage, he has not yet found the use of black stone wood, so he feels entangled.

Li Qi, who was traveling with him, was a guy who was good at observing words and feelings, and when he saw the lord with such a demeanor, he could guess in his heart, so he said tentatively: "Lord, in fact, there is a small suggestion from his subordinates......"

Ye Feng, who was thinking about something, glanced at the other party when he heard this, and slightly raised his head to signal the other party to continue.

"The transport ship is an indispensable maritime tool, but the conventional transport ship has a fatal flaw, that is, the durability is too low, and if the black stone wood is used, the transport ship can have half the durability of a large warship, and it will not have a problem if it travels at sea for ten days and half a month, even if it encounters a little storm." Li Qi said cautiously.

This suggestion is actually very ordinary, but it made Ye Feng's eyes light up, he actually drilled the tip of the horns just now, otherwise such a simple question would not have been unexpected.

Before finding other uses for blackstone wood, it will definitely not suffer a loss to build a transport ship on a large scale, and this kind of high-durability, suitable for long-distance voyages, will play an irreplaceable role in the future, because he can't stay in Yizhou all the time, and when the large-scale main story battle gradually unfolds in the future, he will definitely have to participate.

The two two-way abandoned teleportation arrays can allow his troops to reach the mainland quickly, but the materials must be used by transport ships, starting from Yizhou to cross the strait, ordinary transport ships are estimated to have no durability halfway, not to mention that there is a certain chance of encountering a storm.

Thinking about it, he was no longer entangled, and said in a deep voice: "Li Qi, in the future, you will stay on Blackstone Island and be responsible for the cutting of Blackstone Wood, and report to me immediately if you have anything." ”

Li Qi was shocked when he heard this, this is a heavy responsibility, representing the importance that the lord attaches to himself, so he hurriedly said: "Please rest assured, the lord!" ”

Ye Feng also made a decision, and said lightly: "When the Black Stone Wood is in the ninth grade, I will arrange for people to cut it down by hand, remember!" I'll send fifteen transport ships and a hundred lumberjacks from Maple Leaf Town to maximize Blackstone's timber production. ”

"Yes!" Li Qi said solemnly.

……

In fact, there is nothing to arrange on Blackstone Island, the land here is barren and not suitable for planting, but the yield of the fishery is not low, and self-sufficiency is no problem, so Ye Feng extracted more than 2,500 NPCs from the more than 4,000 residents of Blackstone Town, ready to be transported back to Yizhou......

Blackstone Town is not in a hurry to build, because it is a system town, and there is no even a rebel gathering point, and the value is greatly reduced, and when it is upgraded to the city level in the future, it is estimated that there will be a rebel battalion.

But that's all later, he is now paying more attention to the construction of Yizhou, so he has transferred so many people.

The next morning, a full twenty large warships set off from Blackstone Island and sailed into the vast sea.

It is worth mentioning that the number of large warships that Ye Feng now has has a full twenty-six, including three from Maple Leaf Town, and the rest are all captured from the three groups of pirates.

This time, he left behind 300 soldiers, scattered on three islands, and maintaining law and order was basically not a problem.
