Chapter 151 Pill Fusion_4

Cao Zhen had been holding Yu Tuoyu and naturally made his way toward the tower in the center of the city upon hearing the call.

This was an incredibly bustling city, with streets teeming with carriages and horses, and a constant flow of people. Its area was much larger than Yu Min Town, which they had passed through earlier. There were many buildings within the city, but the tallest structure was the seven-story tower at the city's center.

The tower mentioned by the other party must be that one.

As Cao Zhen walked along, he noticed that the citizens within the city had very healthy complexions, showing no signs of being affected by Demonic Qi, indicating that any Demonic Qi here had been completely suppressed.

Although he didn't fly, his pace was much faster than that of an ordinary person.

In no time, he arrived outside the tower.

The tower was grey, and though there were no guards stationed around it, no citizens approached it either.
