ancient portal

A lot of people saying that Minecraft is easy,so why don't we use the portal from the ancient city and make it one way portal,no coming back except the only way to come back is to travel 1000 away from the world center the place will be 200x200 and it will be look like an arena and you have to kill 200 of the deep dark mobs to the portal frame to appear, and another idea is to make the bacon focus only on one direction forward,backward,left and right, BUT, we use the echo shards on the bacon and he make an sound waves and to open the portal you should stand on it and make the bacon and warden sound beam hit the portal frame at the same time you will teleport instantly back to your world.
