Kung Lao was the first to find the body of his friend and fellow Shaolin monk Liu Kang. He later discovered that it was in fact Shang Tsung who had dealt the fatal blow. Enraged, Kung Lao abandoned his Shaolin beliefs and vowed revenge against the sorcerer. He knew that his fighting skill would not be sufficent to best Shang Tsung. He would need training from the same Outworld master who had taught Liu Kang one special attack he needed to win the Mortal Kombat tournament so many years ago.
Rage fueled Kung Lao's thirst for revenge. The memory of holding his
fellow monk's broken body on the lei tai of the Wu Shi Academy grounds
consumed him as he rained blow after blow down upon Shang Tsung. Kung
Lao had finally mastered the attack Bo' Rai Cho had taught him. The
sorcerer could not withstand his whirlwind assault. Shang Tsung begged
for mercy. Kung Lao granted him none.
Upon his return to Earthrealm, Kung Lao stood before the modest shrine
to Liu Kang which had been erected by the Wu Shi initiates during his
absence in Outworld. He lit a stick of incense and placed it among the
others already burning there. He bowed his head and prayed for safe
passage to the afterlife for his friend and brother. With Shang Tsung's
death, Liu Kang's spirit could rest peacefully. Earthrealm was safe
once more, but at terrible cost. The work of the White Lotus society
had become more important than ever.
