Seeing the sand back in his backpack made Lu Chen a little excited. He had never thought that sand could be used as a material.

"In this case, does it mean that the materials can not only be obtained from the wooden box, but also if the stones are dug out?"

With this idea in mind, Lu Chen looked at a few stones in the distance. If the stones could be turned into stone, wouldn't he be able to make a city wall? There would be no need to worry about monsters appearing at night.

But for now, let's plant the seeds and see what they can turn into. If it's food, that would be the best. If it's trees, that's not bad. At least you won't have to worry about the wooden boards, although I don't have to worry about the wooden boards now.

Lu Chen dug a total of 3X3 square meters of land and obtained sand*9.

Lu found the seeds, placed them some distance apart, and then buried them in the sand again.

[Seed-12, Sand-9]

Seeds will not grow for no reason. They also need water. Naturally, they cannot use sea water and need fresh water. It seems that his fresh water reserves are not enough. Now Lu Chen regrets selling the fresh water.

Lu Chen still had ten bottles of mineral water, and then he started watering them.

A bottle of mineral water was poured down, and soon the sand absorbed all the water.

"No, this bottle doesn't feel moist at all?"

Lu Chen flinched a little. After all, fresh water is limited now. Although there is a water purifier, if the fresh water runs out, he will not even have anything to drink.

If you think about it carefully, if these seeds can bear fruit, the water will be worth it.

Lu Chen's heart skipped a beat: "Fight 1"

【Mineral water-9】

All nine bottles of mineral water were poured down, and Lu Chen's heart was bleeding.

Fortunately, these nine bottles of water have made the sand moist, and Lu Chen finally saw hope.

Now that everything is done, it’s time to get the rocks.

Looking at the several big rocks in front of him, Lu Chen thought again. Previously, shovels were needed to dig the soil, but now the rocks should be used as mining picks.

Lu Chen did not hesitate and directly opened the synthesis interface.

Iron ore pickaxe: wooden board*3, iron plate*1

Make!

[Congratulations on getting the iron ore pickaxe*1]

[Wood board-3, Iron plate-1]

Iron Ore Pickaxe: Can be used to mine ore resources.

Lu Chen picked up the mining pick and smashed the stone in front of him. This time, the stone was not easily broken into pieces, but it was smashed into a gap. Seeing this, Lu Chen smiled with satisfaction.

"Okay, as expected of a mining pickaxe, I'll smash it!"

Dang Dang Dang!

Lu Chen started mining again, and after five strokes, the stone in front of him was finally reduced to debris.

[Congratulations on getting stones*10]

oh!

It was a stone. It was a good deal. Lu Chen looked at the other stones and chopped them into pieces one after another.

[Congratulations on getting stones*10]

[Congratulations on getting stones*10]

[Congratulations on getting stones*10]

...

Finally, with Lu Chen's efforts, sixty stones were obtained.

Looking at his harvest, Lu Chen also smiled with satisfaction.

When I looked at my physical strength, I actually lost three chicken legs. It seems that smashing rocks is a bit physically demanding, but it's worth it.

The next step is to make the city wall.

Just when Lu Chen was about to leave to build the city wall, he discovered that there was a stone underneath the dug stone. It turned out to be a black stone.

"Black stone, what is this?"

Lu Chen squatted down curiously and touched it.

"Iron stone? Could it be iron ore?"

Lu Chen was surprised this time. He didn't expect that he would make an unexpected discovery. If it was really iron ore, he would be rich. He remembered that iron ore could be made into iron plates. If he had iron plates, he could make some.

Although iron tools now have iron plates, the number of iron plates is not large. If you can get more iron plates, they will always be much stronger than wood products.

Lu Chen picked up the iron ore pickaxe and smashed it. This time the smashing time was obviously longer than that of ordinary rocks. It took at least ten hits before the stone in front of him finally broke into pieces. However, the loot was quite a lot. He actually got

Got ten iron ores.

[Congratulations on getting iron ore*10]

Now Lu Chen understands a little bit. This may be the mechanism of the game. Mining ore will obtain ten materials. However, the harder the stone, the more difficult it will be to mine. However, Lu Chen also saw steel ore in the synthesis interface.

If you are mining stones with a steel ore draft, the speed may be increased.

Now that I happen to have a steel plate, I might as well give it a try.

Lu Chen opened the synthesis interface.

Steel ore pickaxe: wooden board*3, steel plate*1

synthesis!

[Congratulations on getting the Steel Mine Pickaxe*1]

[Wood board-3, steel plate-1]

Looking at the steel mining pick in his hand, Lu Chen then smashed the stone below.

As a result, I only hit it twice this time, and the stone shattered.

[Congratulations on getting stones*10]

Looking at the broken stone, Lu Chen was overjoyed. Now he knew exactly what to do next. Mining the ore to obtain stones or other ores, and the speed depended entirely on the weapon in his hand. The so-called desire to work.

To do something well, you must first sharpen your tools. This is the truth.

But it was a pity that Lu Chen did not find more iron ore, and there were no stones below. It seemed that the mineral resources on this island were very limited, so Lu Chen had no choice but to turn around and leave.

Lu Chen returned to the little sloth. This guy gave Lu Chen two more wooden boxes, one of which was green. This was a very good result.

Open white wooden box.

[Congratulations on getting wooden boards*6, mineral water*3, and bread*2]

Good guy, this is a pure grain box. Lu Chen was very happy. Now he has four pieces of bread. It seems that he can eat one piece of bread in a while.

Opened green wooden box.

[Congratulations on getting wooden board*6, stone*10, glass*3, iron plate*1, steel plate*1, apple*2]

The green wooden box has never disappointed, and the resources provided are still so many and so good.

Lu Chen saw that he now had a lot of stones, and it was time to start making the city wall.

Open the construction page. A city wall is 3X5 in area and requires 10 stones.

Lu Chen calculated it and found that his island now visually measured 10X10. He now has 100 stones, and the length of each city wall is 5. After all the stones are built, the maximum length is 50, which can only cover half of the island.

If this doesn't work, then he can only narrow the scope. The seeds he just planted cannot be discarded outside, and he must leave space for the base. After calculating this, he needs to measure it carefully.

Then Lu Chen started measuring, everything was completed, the distance was drawn, and now construction began.

【Stone-10】

Making the city wall is very simple. Just click Build and set the location, and the city wall will automatically appear. And the moment the city wall appears, the words upgrade and dismantle will appear on it.

upgrade!

[Buzz, upgrading the city wall requires iron ore*10, do you want to upgrade it?]

If it actually requires iron ore, then it’s better not to upgrade for the time being. You can only upgrade it after you get all the iron ore.

The city wall can still be selected at the corners, and the construction system is still very user-friendly. Soon, Lu Chen's city wall was completed.

【Stone-90】

Two days after survival, a small castle appeared on a small island, which was quite a feat.

Lu Chen left a two-meter-wide door. This is a must. Otherwise, how can one get in or out without a door?

Normally, he could leave his little castle during the day, come back to rest at night, and put a torch at the door, which was great.

The seawater purifier is still working continuously and has filled five water bottles. Now Lu Chen is finally relieved that he still has enough fresh water.

Another white wooden box appeared next to Lightning Shuang.

Lu Chen praised Lightning for his ability and then gave him an apple.

[Congratulations, pet intimacy +10]

Open the wooden box!

[Congratulations on getting wooden board*6 and carp*2]

Not bad, today's income is still very considerable, at least I have all the food.

Lu Chen looked up and looked into the distance because he found something wandering in the sea.

It's a shark, yes, it's a shark, lots of them, at least ten.

"Why are there so many sharks?"
Chapter completed!
