K3 pointed a gun at Hong's head.

In episode 21 of "The Lone Path," Hong (Doan Quoc Dam) is sitting thoughtfully in his room when he hears the doorbell ring. After identifying the person outside as K3 (Truong Hoang), Hong opens the door only to be surprised when K3 points a gun at his head. Previously, in his plan to assassinate Hung "Khec" (NSƯT Chi Trung), Hong had always sidelined K3.

"It's pretty tough," K3 said, while Hong looked bewildered, not understanding what was happening.

Also in this episode, Dung "Kinh" (Manh Cuong) approached Trinh (Ba Anh) to try and recruit him to work for Quan "Gia" (Vinh Xuong). However, the professor was tactful enough to let Dung know he didn't want to. Nevertheless, Dung "Kinh" didn't go to Trinh's house to hear the refusal.

"The village of Bản Mộc now needs someone with enough credibility and ability to stabilize it. In this area, there are only Boss Quân, me, and you. Do you really want me or Boss Quân to come down here?" Dũng said.

The "professor" replied: "Unfortunately, you've already dismissed someone more capable than me."

"Hong? Hong and his brothers might not even make it back. You've misplaced your loyalty. Everything is chaotic right now. That's why I'm still working myself to the bone. So I don't have time to waste. Give me an answer soon so I can report to the boss," Dung "Kinh" continued.

In another development, Khuong (Duy Hung) is asked by Hong to count steps to measure the length of Hung "Khec's" house. However, Khuong, while drunk, inadvertently reveals his brother's plan to Tuan "Sat" - Hung "Khec's" closest henchman.

"A hundred steps a day brings good fortune and improves health," Khuong explained to Tuan "Iron." Tuan "Iron" kept asking questions, confusing Khuong. Khuong complained, "Why do you always interrupt me every time I count? I'm counting and you keep interrupting, I can't remember what number I'm at! Get lost!"

Tuan "the Iron" said: "If you want to train well, your mind needs to be clear. Just move as hard as you can, but stop counting."

"Oh dear, my brother asked if I could count yet. He said he'd researched this field very thoroughly. He said I have to count my steps every day to improve my health, understand?" Khương said, inadvertently revealing Hồng's plan to Tuấn "the Iron Man".

The detailed plot of episode 21 of the series "Doc Dao" will air tonight (October 16th) on VTV3.
