After descending twenty meters underground, the tendrils transformed into finer threads and began crawling towards the inner city of the Royal Palace.
Though crawling, its speed was actually quite fast.
Chen Xuan estimated that it could reach about fifty kilometers per hour.
Logically, the underground is all solid earth and does not facilitate passage, but in reality, there are many gaps between the soil that are hard to observe with the naked eye, and these dispersed threads are finer than earthworms, so weaving through cracks is not difficult at all.
Tens of thousands of threads advanced on different paths; whether they encountered obstacles or discovered more accessible routes ahead, they could share the information with other threads, constantly converging, fusing, and then dispersing again, ultimately forming an underground network approximately a hundred meters wide.
