Yan Feng pursed his lips and said in a low voice, "In that case, Old Wang wouldn't have died."

These words silenced everyone.

Lu Ning glanced at Yan Feng. Since the last incident, Yan Feng's personality had changed a lot.

That carefree, nonchalant attitude of his was rarely seen before.

Lu Ning calmly said, "My strength is still far from that of a Saint."

He recalled the battle between the Azure Mist Saint and the Blood and Flesh Source Avatar.

Even without using a high-risk soul weapon, the power of that tornado was beyond what the Azure Mist Saint could currently achieve.

However, if a Soul Weapon is used, it can easily unleash wind blades that travel several kilometers or even further.

Moreover, the sharpness of those wind blades was such that they could easily cleave even a physical body like the flesh and blood source clone in two.

Lu Ning compared the strengths in his mind and realized that the gap was still quite large.

He estimated that he would need to reach the seventh rank to have any hope of achieving that.

The road ahead became even more difficult, with large groups of monsters appearing from time to time.

Although Lu Ning was able to kill him, it took him quite a bit of time.

And gradually, everyone's hearts became somewhat heavy.

With so many monsters, you can imagine what the Second Frontier Fortress was facing.

Whether they can hold on is unknown.

Nearly an hour later, they arrived at a high mountain not far from the second border fortress.

When they saw the scene below, everyone's expression changed slightly.

The entire border fortress has been reduced to ruins.

Some of the invasive beasts and diseased individuals are patrolling back and forth within the ruins.

What's somewhat puzzling is that the infected and the monstrous beasts shouldn't be able to break through the city walls.

As a result, the city walls and the buildings inside now seem to have been crushed by some extremely terrifying and powerful force.

This kind of power is something that even a sixth- or seventh-level cultivator shouldn't be able to achieve.

Yang Xue frowned and asked, "What happened here?"
