Chapter 670: Mysterious Old Man

Zhou Hao was still in the thirteenth ancient ruin, and now, there was only a stone tablet left!

However, the stone tablet was still very difficult for Zhou Hao to break through!

"More than ten months have passed outside. I wonder if Dad, Mom, and the others are alright. I wonder if Xu Ling is alright. They will definitely think that I'm dead!"

Zhou Hao was very worried, but he was really helpless. After all, he had already used his full strength, but the outcome was still the same!

"Looks like I have to take it slow!"

Zhou Hao took a deep breath and continued to practice!

Soon, after half a day, Zhou Hao finally punched out and immediately shattered the stone tablet!

It was also at this moment that the secret room instantly disappeared. However, in the next second, Zhou Hao did not appear outside. Instead, he arrived at a very strange place!

In this place, there was a very strange magnetic field that connected to the ground!
