Messenger from the Other Side: Paranormal Investigation Records

Before his death, grandpa called Zhao Junchen to his side and told three things: "First, the musket buried in the cellar will be left to you for safekeeping after I die;" "Second, you will encounter some beings that are completely beyond your knowledge in the near future - I will leave four tips for you, which can only be opened in critical moments;" "Third, you must not trust the guy who claims to be your uncle!" In the early morning of the first seven days of my grandfather's life, my uncle, who had been kidnapped by a ghost, broke into Zhao Junchen's bedroom... After using the ghost gun left behind by his grandfather to kill his uncle, Zhao Junchen opened the first kit. What came out was Huang Fugui, who had been with his grandfather for many years.

What other treasures would be found in the bag left by his grandfather...? Looking at the heavily armored warrior kneeling in front of him, Zhao Junchen's eyes widened—— "The last general, Yanzhao, the sixth man of the Yang family, has caused great harm to the officials!"
