Long Chen was able to see some core memories of the Sun Destroying Condor which finally made him understand why it was so against the taming.
Apparently, when the Sun Destroying Condor was young, it was a tamed beast of a person.
Surprisingly, the person was the son of the Sect Master of Thunder Giant Sect.
The son of the Sect Master was a little ruthless and let out his frustration on the Sun Destroying Condor quite a lot of time.
Since the Sun Destroying Condor was quite young and weak at that time, the master tortured him a lot whenever it was defeated in a battle.
Fortunately, the master was assassinated one day and the Sun Destroying Condor was freed of the Contract.
The taming contract worked in quite a mysterious way. One of those was that whenever a master was killed, the tamed beast would be released as long as the tamed beast never disobeyed its master's orders during its lifetime. Thus the Sun Destroying Condor gained its freedom and flew away.
