Even though Lin Su and the three little ones went without sleep or rest for seven days and nights, it would be impossible to collect all opportunities in the Tianjiao battlefield.
After all, acquiring opportunities takes time, and some are not always available.
For example, the Luck Blessing Pool opens once a month, and similar Opportunity Lands are quite numerous in the Tianjiao battlefield.
Some of them were already claimed by the major sects before Lin Su entered and are no longer obtainable.
But overall, the Opportunity Lands in the Tianjiao battlefield still have surplus value for Lin Su.
To efficiently collect these opportunities, Lin Su already asked Rong Venerate for an internal opportunity list before entering and had his targets picked in advance.
After leaving the Dark Temple, they visited one by one all the places beneficial to Lin Su, Qiuqiu, Gui Gui, Youyou, and even Yingying.
In the blink of an eye, seven days passed.
