Liu Zhongfu was a grandmaster, so whoever caused him to cough up blood from playing chess was naturally an even more extraordinary expert.
But why would such a master become fixated on one corner?
Yang Yao didn't understand, but such a game truly broadened his horizons and made him realize the superficiality of his previous understanding of the game of Go.
When Wanyan Lie struck the bell and made his move, he slowly asked again, "Shen Yue, do you know who is holding the white pieces?"
Shen Yue pondered, "Liu Zhongfu?"
That wasn't hard to guess.
Normally, anyone who understands chess and held the white pieces at this moment would either be puffing with anger or coughing up blood.
Puffing with anger because they were being completely outmatched, without any chance to fight back; coughing up blood because they refused to let go.
Liu Zhongfu was the one coughing up blood.
