Actually, many critical moments didn't have too many signs before arrival; instead, they came as natural as evening sunglow, thunders on rainy days and silkworms breaking out of cocoons. They always appear silently. When you understood that your choice would determine the fates of you and many people around you, the critical moments had already elapsed, leaving no chance for you to make a choice again.
Zhang Tie didn't know that he was facing such a choice. He only felt that the last tracing feather was very weird and had a strong will to reach the top of the main peak. Although he didn't know the guy's final target.
He had a few options.
First, ignore the weird mist. After all, there were three earth human knights here. Additionally, the new arriver didn't notice the existence of Zhang Tie. If the weird mist caused some trouble, the three earth human knights would handle it for sure.
