Having already entered the prince's residence and learned the details of the key figures within it, as well as Third Prince Xuanyuan Wuji's daily routines there, Zhang Tie naturally would not simply leave, even with an obstacle blocking his path.
To gauge Tutor Xue's strength, there was another way besides fighting him directly: observe him up close, or test him.
The instant he thought of observation and testing, Zhang Tie came up with a method. At a time like this, the power of the Great Wilderness Scripture Zhang Tie had mastered could truly be displayed.
There was an animal in this world that had survived for hundreds of millions of years without going extinct. Wherever people lived, traces of them could be found. That animal was the cockroach. Among the Hua Clan, cockroaches also had a particularly affectionate nickname: Little Qiang.
Cockroaches had wings like insects, but ordinary cockroaches could not fly; they could only glide. After the Great Cataclysm, however, as long as there were enough cockroaches, a small portion would undergo slight mutations. Their wings gained stronger flight capabilities, allowing them to fly three to five hundred meters at a time over short distances. They also became better at concealing their auras and possessed greater survivability. Some could even change their body color like chameleons or become semi-transparent. Such cockroaches were called Flying-Wing Cockroaches—like special forces among cockroaches.
Relying on the abilities in the Great Wilderness Scripture, Zhang Tie merely spent a little time circling the outer perimeter of the prince's residence before easily summoning several Flying-Wing Cockroaches. He then cast a Super Concealment Technique upon them, making their auras even fainter and harder to detect. Afterward, the little black beetle he had transformed into led those Flying-Wing Cockroaches straight toward Third Prince's residence within the prince's estate.
