Bab 392: Upgrade.

Shi Lang decided to place the array core later and held Shi Tao's hand. Then he appeared outside the valley. He looked at the guard who was staring at him as if he has seen a ghost and said, "Channel the message, till the black clouds disperse, this valley is off-limits. If someone wishes to seek instant death, then feel free to explore." 

The guard nodded hastily and began to pass on the message. Shi Tao asked, "Dad, what is that?" 

Shi Lang said, "That, my dear, is a heavenly tribulation." 

Shi Tao asked, "What is that?" 

Shi Lang sighed and said, "When your cultivation reaches a level where your existence is something against the rules of the heavens, they send out a tribulation to test your worth. If you can pass the tribulation, then your foundation is stable and your strength increases. However, failing the tribulation means death." 

Shi Tao nodded and said, "Does that mean I will also have to face this tribulation?"
