I want to select a number 10000 which in the middle of 00811000013600012. I already use split which I have split a single number and know I have a problem to combine the number to get my payload 10000. Please help me.

If you always want the 5th to 10th characters you could use a function node and substring().
Output as a string:
msg.payload = msg.payload.substring(4,9)
return msg;
Or as a number:
msg.payload = Number(msg.payload.substring(4,9))
return msg;

To do it with a split node use between in the switch node and check recreate message sequences
Then use a join node set to automatic
e.g.
