What I did until many slimes spawn on slime chunk

What I did Waiting place and not to spawn mods Create Multi layers Sprinkling is the most difficult About timing when slime spawns Once Despawn A sure way Build slime farm trap tower Conclusion What I did First I found a slime chunk using Slime Finder . This is the basic in the basics. Dig into Y=40 heights in the slime chunk found. From there continue to create a space of height 3 until it hit the ground. Fills a range of 128 squares from the slime chunk with torches. Wait at least 28 blocks and not more than 128 blocks from the slime chunk. The above is the basis of how to spawn slime. But I did not spawn a lot of slime with just the above. So I repeated a lot of trial and error. Waiting place and not to spawn mods Once you have created a layer, you have to wait in the range from 28 to 128 blocks from there. And mods must not to be spawned against X axis, Y axis Z axis within 128 blocks from this waiting place. You must make the range of 128 block
