Zhou Heng was digging merrily below, while those above found it especially difficult to stop him.
A distance of over a hundred zhang was too great for even someone at the Land Cleaving Realm to leap across, and since the tunnel wasn't straight, it was impossible to launch a hidden weapon for a sneak attack. To stop Zhou Heng, one would have to go down personally.
But with the depth of the enemy unknown, who would dare to rashly descend?
The tunnel was so narrow, there wasn't room to move about, and if one met an opponent stronger than oneself, there would be no way to retreat, leading straight to death!
Anyhow, they did not believe that Zhou Heng could so accurately locate the Spirit Core, and someone had already gone to summon the Big Shots of the Open Heaven Realm; it was entirely possible for an expert to deal with Zhou Heng, so there was no need to risk their own lives.
