oral gagging and bondage (idiom); fig. pressure to stop a person's mouth from shutting and bind him

Li Yun could feel the other party's bodily functions improving, though not as noticeably as Wang Lu's. [You have reached the second level of the Natural Mind Method, and can now cultivate actively on your own.] [You currently only master the basic Spirit Binding Charm of Maoshan, and a bit of ability relying on the Silence Imbuement.] [I suggest you go find some residual cultivation techniques or secret treasures!] "Can that Silence Imbuement enchant anything?" [No, only inanimate objects that would physically have a silencing effect, such as gags, tape, stockings, cloth... Even oddly shaped stones won't work!] "Okay." Where should he look for these residual cultivation techniques? As Li Yun pondered, Tang Manru reminded him: "Thank you, I'll pretend today never happened... Can you lend me a..." Liu Xin was greatly alarmed. She only saw a pair of stockings fly out, and then her vision became extremely blurry. "Who are you!" He guessed that Li Yun was sent by some organization to kidnap him. Although his identity was highly confidential, there might be some powerful organizations that knew his true identity. While his mouth was occupied with speaking, Li Yun held a jade-like ball gag in his hand. "You want... Mmph?!" This was a ball gag refined after being enchanted with ice, it wasn't extremely cold, but instead secreted a comfortable liquid. The melting of the ice required the female's arousal fluids; otherwise, the ball gag would become increasingly cold. Liu Xin opened her mouth to try and spit out the ball gag, but Li Yun roughly grabbed her mouth and then reached out to tear off a piece of the enchanted transparent tape. "Rip!" The tape sealed Liu Xin's constantly wriggling lips. "Mmph... Let... me... Mmph!!" Liu Xin turned and threw a punch, which Li Yun easily dodged. Inside the elevator, Liu Xin, with one foot bare, revealed her stocking-clad beautiful legs as she stepped on the ground, hopping around. Her eyes were covered with white silk, and she looked around, unaware of her surroundings. The tape on her mouth seemed to have sealed it shut. She found that even if she used a secret method to vocalize directly through her vocal cords, it would be very difficult. Li Yun hugged her and tied her hands behind her back. Liu Xin was terrified, then leaned against the corner of the elevator, continuously kicking out with her legs, striking her surroundings. Li Yun roughly pinned her down and pinched her beautiful lips, which were covered by stockings. He shouted, "Spirit Binding!" Mysterious runes flowed through his energy output onto the stockings. The ordinary calf-length stockings turned into a semi-liquid gel, filling her mouth. The white silk covering her mouth acted like the most adhesive tape,缠住 her mouth, preventing her from speaking. "Mmmmmph!!" "The witch of the Wu family, possessing over a dozen clone puppets, she loves to role-play as a student, but this also causes her mind to temporarily go astray, and she forgets her identity. Only with voluntary cooperation will she suppress her power; otherwise, any forceful act will easily trigger the witch's mechanism. You are more like an esper from the cultivation world." The witch Wu Jiajia cried out loudly, her muffled cries echoing. She regained her strength, pushing herself up with her hands, but did not attempt to escape. Instead, she activated her lower orifice, and an infinite devouring force pulled Li Yun inward. Although Li Yun was prepared, he was still startled.
