This guide will tell you how to find Netherite in Minecraft Pocket Edition 1.19.
1- You will get Netherrite from NCN depries as the NCN depries are generated in the Nether dimension from y-level 8 to y-level 119. If you dig on the top, then the lava will always disturb you and if you dig down, then the bet rock will disturb you. So you have to start mining at y-level 15 and then start doing strip mining. For this, you will need to have a diamond axe and then start digging in the downward direction.
2- Now the second method to do this is by creating a sheep farm and then collecting a lot of wool from that farm. On the crafting table, you have to put it on wood and then create a lot of beds.
After this, go back to nethers, and go in the y-level 12. You have to dig a long tunnel and then on every side, you have to dig 5 blocks. At the end of these five blocks, you have to place a bed and then click on it. The bed will explode and it will destroy all the blocks around it. Then you will find NCN depries there.
