I found somewhere that NodeMCU works without level shifting on RX/TX. So, I tried without level shifter with another NodeMCU and 2 TTL
All are components are working fine and I think no component is damaged.
But can't figured out what is the problem.

Thanks for you response

and nothing happen in console when I typed and uploaded code which is provided by you.
Here is my connection to NodeMCU
TTL 5V-----------------------------------NodeMCU 5V (VCC IN)
TTL RX-----------LEVEL SHIFTER----------NodeMCU TX
TTL TX-----------LEVEL SHIFTER----------NodeMCU RX
TTL GND---------------------------------NodeMCU GND
