As he listened to the void snake tribe cultivator's description, Tang Zhen could not help but recall the scene of the blood sacrifice back then.
On the boundless sea, hundreds of thousands of native cultivators from the foreign world looked miserable. Under the watch of countless cultivators from Lou city, they were transported to the water world in batches.
Under the secret technique of the cultivators of Lou Cheng, these native cultivators of the foreign world were forcibly fused with the summoned creatures, each of them unrecognizable.
After that, they died in batches under the butcher's knives of the cultivators in Lou Cheng, becoming sacrifices to commemorate the dead.
That kind of bloody massacre would definitely leave a deep impression on anyone. No wonder this void snake tribe cultivator could still remember it so clearly even after so many years had passed!
Tang Zhen recalled the scene he had seen earlier and the doubt in his heart was answered.
