There are new structures for speed. If you cant find villages and it takes to long time to find a village, you can craft a blacksmith house! There are more, you can craft:
Blacksmith House (Chest have diamonds, obsidians, breads, irons, golds and more)
Ruined Portal (Chest have fireballs, flint and steel, all gold items and armors; portal have lots of gold blocks, there are iron and diamond ores behind the portal)
Small Nether Room (There is Enderman and Blaze spawners and a nether wart farm and a chest; Chest have a netherite sword, lots of ender pearls, lots of blaze rods and lots of water bottles for putting out blaze fire)
Stronghold Portal Room (There is a hidden Shulker box under the lava; Shulker Box have lots of scaffolding for climbing to obsidians, lots of snowballs for exploding end crystals and lots of beds for defeating Ender Dragon)
End Ship (A normal End Ship but there are Shulker Army! You cant even get loots with netherite armors and totems! to get the loot, you must craft a Anti Shulker. Chests have more loot than I can count! Totems, Netherites, Dragon and Wither Heads, and more! But there is a hidden Shulker Box between Shulkers, Shulker Box have even more loot! All Netherite armors and tools and more including loots in chests)
Anti Shulker (To get Anti Shulker, you must merge iron helmet and Shulker Shell in the Smithing Table. If you wear it, you can't even jump one meter tall, but you have infinite slow falling and speed effects but more importantly the Shulker Bullets will disappear and all Shulkers will poison! Now Shulkers can't fire to you!)
Netherite Upgrade (Open the brewing stand and put netherrack instead of bottle and put diamond on top, this requires blaze powder, you will get Netherite Upgrade instead of potion!)
For the first recipe, you must place a Furnace, then for the other recipes you must craft previous recipe.
Good Luck!
