I try to ping outside internet from Mikrotik terminal but I can't. I tried to ping gmail.com IP as

gmail.com IP is: 74.125.236.53

> ping 74.125.236.53

output:

timout

But If I ping my local system I can able to do as

> ping xxx.xxx.xxx.206

output:

connected

Why can not I able to ping outside my LAN connection?

Check your filter rules and if you have a default gateway for the router

I don't have any filter and NAT rules. What else I need to check?

Maybe is not having a NAT rule the issue.
Hoe are you connected to the internet and how is your IP setup?

ether1-Input:
Address = 10.0.0.2/30 Network= 10.0.0.0

ether2-LAN:
Address = 121.222.121.193/28 Network = 121.222.121.192

IPs specified are not correct. I pick some random number.

If you do not have any NAT rules, you won't go far from home. You should probably have at least this:
/ip firewall nat
add chain=srcnat action=masquerade out-interface=ether1
If ether1 is not your WAN interface, change that.
