The blood trail that Liu Dongyuan was following at the time was also from Wen Bao's right leg being grazed by a bullet.
However, when he tracked it to the riverbank, Wen Bao had already jumped into the river and could no longer be chased and captured.
Speaking of Wen Bao, he truly was skilled, a kidnapper with principles, indeed worthy of being the top figure in Southeast Asia's underworld now.
At that time, his escape route was pre-scouted by him.
In other words, when planning the whole kidnapping, he had also pre-emptively thought about what to do if it failed. The only option would be to escape, and there are many ways and many reasons to initiate an escape.
All of this was part of Wen Bao's plan. Therefore, after being dealt a heavy blow by Sea Wolf led by Liu Dongyuan, Wen Bao naturally used that escape route.
Successfully jumping into the river, he drifted over thirty kilometers downstream, then went ashore and escaped.
