As soon as Sanguine Warflag built the guild headquarters in the centre of Viper Valley, the snakes started surrounding the headquarters.
As the system's countdown ended, four golden beams appeared in the four general directions outside the headquarter.
The four bosses had appeared amongst the monsters.
The reason Viper Valley was harder to defend than Dawn Canyon was mainly due to the four bosses.
It was important to take advantage of the landscape. However, if there were four bosses at Dawn Canyon back then, Quan Zhen Sect could not have defended their headquarter with eight men, despite Fearless' ingenuity.
The Quan Zhen Sect members all stood on the observatory tower, so they could see the bosses clearly.
