According to the information Lin Fei received, the opposing force numbered twenty thousand, while they only had a mere thousand, making it impossible to defeat the enemy. Since defeating them wasn't an option, Lin Fei had no reason to send his brothers to their deaths.
Therefore, before any confrontation took place, Lin Fei instructed everyone to retreat immediately, bypass the Trackless City, and head toward a distant stronghold.
When Python and Tiger arrived, they found no trace of Lin Fei. They eventually split up to search and finally found the footprints left by Lin Fei and his group. After considering this, Python and Tiger decided to send people to follow them.
