After setting up the barrier, Chu Wanwan nodded in satisfaction. She believed that even if enemy reinforcements arrived, they would be unable to detect this invisible train.

The old Taoist priest stared at the scene in disbelief, speechless for a long time. He had originally thought Chu Wanwan was just a thief, but he never expected that she could actually draw such a high-level talisman with the Spirit-Guiding Brush.

Chu Wanwan put down her pen, looked at her work with satisfaction, then turned to the old Taoist priest with a smug smile on her face: "Grandpa, you see, I wasn't wrong, was I? This pen really can help us do great things."

The old Taoist priest snapped out of his daze and stared wide-eyed at Chu Wanwan: "You... how could you draw such a talisman?"

Chu Wanwan smiled slightly and walked over slowly: "Because I am also a member of the Xuanmen!"

As Chu Wanwan spoke, she handed the spirit-guiding brush in her hand to the old Taoist priest.

"Now this can be returned to its rightful owner, sir. Thank you for your pen! Your pen helped the Eighth Route Army preserve a large amount of weapons and supplies. You made your contribution to the victory of the War of Resistance."

Chu Wanwan smiled and flattered the old Taoist priest. She really wanted this pen. In her previous life, before she could guide spirits into her body, she also had such a pen. This kind of pen was extremely rare and was definitely a great treasure in the Xuanmen (Taoist sect).

With it, the Eighth Route Army would surely be able to win more victories.

"You're also a member of the Xuanmen sect? Was what you just created the legendary invisibility talisman?" The old Taoist priest took the pen and looked at Chu Wanwan in shock.

"Yes!" Chu Wanwan felt disappointed when she saw the old Taoist priest put away the spirit-guiding brush, but she still smiled.

"Truly, the younger generation is to be feared! I never expected that you would have such cultivation at such a young age." The old Taoist priest exclaimed with deep emotion, looking at Chu Wanwan with astonishment in his eyes.

Chu Wanwan chuckled and said modestly, "Not at all, Grandpa, your pen is truly amazing! I'm just using your precious pen to do something small."
