A Tunnel Ten Thousand Years Ago

After the general direction was located, what they were going to do next was easier.

Li Yao, Long Yangjun, Li Jialing, and the two "information lives" that had just been born, as well as the two kids' toys, namely the super-tiny spiritual puppets that were like ants and those that could fly freely like wild bees, set off immediately and explored toward where the special waves came from along the current cracks and caves.

After every three hours, they would stop and reactivate the "soundwave detector and collector" to locate the source of the quakes.

As they expected, the waves were getting more and more intense and clear, suggesting that their direction was not wrong. In the meantime, according to the increased waves, it was possible to further adjust the direction and the depth.
