One of the most deepest impressions Yan Liqiang developed in his previous life was from a visit to Zazhi Cave prison.
Prior to the visit, he didn't really know that much about Jiang Zhuyun's strength or the cruelty of the prisons set up by Kuomintang's military agents. He had only heard about them at most and that wasn't enough for him to form any impressions of it. However, after he visited Zazhi Cave and saw the various torture devices in there like the tiger bench, chili pepper water, and branding iron, Yan Liqiang truly felt a deep veneration for those revolutionaries who could still remain unyieldingly loyal under such circumstances.
The impact of messages conveyed through visuals and immersive experiences were incomparable to other methods, regardless of depth or magnitude.
