Another seven days passed.
During this time, Lu Feng once again received the source stone resources sent by Su Qingxia, Zhao Yan, and the others. He also met the present-day Lu Qian'er and helped her complete the enhancement of her half-human, half-array foundation.
Unfortunately, Lu Qian'er carried too many Heaven and Earth Spiritual Treasures invested in her by Artisan Hero. They could not be casually replicated onto others.
Otherwise, terrifying powerhouses could be created in batches.
But...
After fully integrating Artisan Hero's newly comprehended Nine Puppets Array with the many array techniques embodied within Lu Qian'er, a vague preliminary concept began to take shape in Lu Feng's heart.
Even if he could not replicate an existence with combat power as formidable as Lu Qian'er's in the future, a lesser version—especially one aimed at those suffering from grave illnesses, whose mobility was impaired despite their profound cultivation—should yield unexpectedly astonishing results. Not only could it restore their former peak combat strength, but with the aid of arrays, it might even take their power to the next level.

This man was the elder brother of Tuoba Huang, whom they had encountered not long ago.
In terms of offensive strength alone, Tuoba Yu might not have been much stronger than Tuoba
