After Lying Down, My Sister Thought I Was Useless

Su Che traveled to the world of martial arts and became a direct descendant of the Su family in Gusu with a blocked sword vein. When his sister became a famous swordsman genius in Jiangnan, he was guarding the tomb. While his peers were practicing swordsmanship assiduously, he was guarding the tomb. When the family faced a crisis and everyone moved forward bravely, he... Was still guarding the tomb. Because he was unable to practice, he was assigned by his family to guard the most dilapidated "Unknown Sword Tomb". He became a martial arts loser in the eyes of everyone and was a shame to the Su family. The genius sister hates that iron cannot be transformed into steel: "Su Che! There are no children in my Su family who don't hold swords. You are guarding a pile of scrap metal. Are you going to be a waste for the rest of your life?" Competitors mocked in public: "Haha, it's unheard of for the so-called swordsmanship family to have people who guard their graves and chew on the elderly!" In response, Su Che just spread his hands helplessly. He also wants to work hard, but his strength does not allow it! Bite! It is detected that the host's heart is still and resonates perfectly with the 'Unknown Sword Tomb', and the 'Sword Tomb Sign-in System' is activated! [Sign in in front of the 'Broken Water Sword', congratulations to the host for obtaining the ninth grade sword intention - 'returning to the sheath'! [Sign in in front of the 'Jinghong Sword', congratulations to the host for obtaining the peerless movement skill - 'Glimpse of Light'! [Sign in in front of the 'Edgeless Sword' and congratulate the host...] Su Che just wanted to guard the tomb quietly, sign in every day to receive rewards, and live leisurely. Until one day, a powerful enemy comes to visit, all the family's geniuses are defeated, and a century-old foundation is in danger. In everyone's desperate eyes, the tombkeeper, who they had always regarded as useless, yawned and walked out carrying a rag. "Um... You are disturbing my sunbathing."
