Tang Ningshan looks at Shao Ruihan with amazement. She didn't expect Shao Ruihan to build his secret base here for such reason. However, she continues to ask "When was this place built? According to what you told me, you went back to A country when you were 18. You should have nothing at all at that time. There was no money, no rights, how could such a secret base be built?" This is also the most doubtful point Tang Ningshan feels. If Shao Ruihan had the ability to build such a place at that time, he should have found clues about his parents' disappearance a long time ago. If this is the case, it's impossible that he hasn't gotten any clue until now.
