The men continued with their work, but some time later they heard one of their dogs barking and snarling at a decaying log. One of the Jakun threw his stick at the log, but immediately a torrent of blood issued from the log causing the man to run back to his friends in fear. His friends thought he was possessed by demons and tried to keep away from him. However, the barking continued so the entire tribe returned to investigate the log. A spreading pool of blood had formed around the log.
In fear they hurled their own sticks at the sight, whereupon a dark cloud gathered in the sky. The thunder roared, the lightning flashed and a torrent of rain fell from the sky. The men grabbed their belongings and ran for cover, but in the chaos one of them pulled the old woman's stick from the ground - the very stick which they had been warned not to touch. Immediately a fountain of water poured from the hole made by the stick. The water flowed for many years, thereby creating the lake of Tasik Chini. The tribe realised then that the log was actually the dragon called Naga Seri Gumum.
Of course, no magical lake would be complete without stories of a resident monster or a long-lost, sunken city. So, Tasik Chini has both ! Much like the famous Loch Ness, a serpent-like monster is reputed to make the lake its home. More seriously, there are theories that an ancient Khmer city once existed in the vicinity which has prompted archaeological studies of the lake and its surrounds.
