The first one block challenge map got a great response, 200 downloads in three days

Since you folks like seemingly impossible but practical challenges I decided to make one block challenge No. 2

In this map you are on top of a large chest.(Picture 1) Actually below that chest is a grass block

That chest is empty(Picture 2)

You have to fill that chest with cobblestone(Picture3)

You are provided with one bucket of lava, one bucket of water and 2 netherite pickaxes

Why two pickaxes, because you have to mine more than 3456 stone blocks and one netherite pickaxe will help you to min over 2000 stone blocks so two are sufficient to achieve your goal. So go ahead and start mining, the daylight is set to false so there will always be light to mine. Let us see how many can achieve this seemingly impossible task but actually practically possible.

Once you learn these techniques you will be able to play all those skyblock map with great ease.

So let us start, hints will be given after seeing how many download and play this map
