Tie Wandao didn't plan to ask, but he was curious and thought that understanding this situation might be helpful for finding the entrance next time, so he asked, "When you just drew the circle, you tied the rope to the nail, right?"

"Yes." Li Pingrundao.

"Where is the other end?" Tie Wandao asked again.

"I tied it to the branch." Li Pingrun replied.

"You have completely straightened the rope?" Tie Wandao asked.

"Yes." Li Pingrun said.

"The rope is so long, can it be used to determine how big the circle is?" Tie Wandao said curiously, "If the rope is not so long, for example, if the rope is shorter than this, then wouldn't the circle be very small?"

Li Pingrun said, "This is a rope used for method, which can be extended or shortened." As he said, he took out the rope ball from the bag and let Tie Wandao see it.

Tie Wandao looked at the rope ball in his hand, touched the rope, feeling that it was not elastic, so he asked, "This thing can only be extended or shortened under the action of spells, right?"

"Yes." Li Pingrundao.

"It has no elasticity in itself," said Tie Wandao.

Li Pingrun and Tie Wandao explained: "When I do the trick, it will determine the length based on the actual situation I measured through the trick, and temporarily fix the length. At that time, I can straighten it and use it to draw circles through the trick. In this case, the range within the circle I draw must be the range I measured through the trick."

"How did you determine the scope?" Tie Wandao asked, "Are you using the funnel-like thing just now?"

While putting the rope ball into his bag, Li Pingrun said, "Yes, I used it to determine it. During my practice, it will move everywhere. If it feels that a certain position may be the entrance, it will secretly leave a sense point on the ground. During the movement, it will feel that a certain place is the entrance, and it will leave a sense point many times. At that time, the circle I draw through the practice will enclose all the sense points inside."

"Can we not see those sense points?" Tie Wandao asked.

"Yes." Li Pingrun said, "It is precisely because we can't see those touch points that I have to draw this circle."

"Can't you use spells to make those sense points appear in other forms?" Tie Wandao asked, "for example, let them shine."

"I'm sorry, patriarch." Li Pingrun said, "I can't make the sense of light. I believe that other alchemists can't do it either."

"Then how do we find the entrance in this big circle?" Tie Wandao asked, "Do you have to wait for your method?"

"That's not necessarily true." Li Pingrun said.

"Some people may be more sensitive to some places that feel for various reasons." Li Pingrun said, "Everyone is different."

"Are you talking about an ordinary person who knows how to spell?" Tie Wandao asked.

"Yes." Li Pingrun replied, "But there will definitely not be many people who are sensitive to the sense point."

"Can ordinary people still do this?" Tie Wandao said curiously.

"Yes, because I have cast the spell here. Just as the effects that may have on each person after casting spells to different people are different, some people will become particularly sensitive to the sense point under the influence of the spells I have used."
