They no longer had to go to such great lengths, using all kinds of rituals and secret arts to reach the Human Realm, only to have less than a tenth of their strength left!
As for why Derek's Heaven's Fist had been obviously overpowered, it was because the archangel Gabriel had intervened.
That Heaven's Fist, which Li Wei had found difficult to withstand, had been Gabriel's full-force attack.
Lucifer and Mez had likewise sensed Gabriel's presence, which was why they had rushed over from Lucifer's The Light Bar.
Li Wei had previously found it strange that the Heaven's Fist had been so fragile in Mez's hands.
It was not that Mez's strength could crush Gabriel's. Their true strength was roughly on par.
It was simply because Gabriel had violated the agreement Heaven and Hell had made long ago by directly using her power to interfere in the Human Realm. Lucifer had caught her in the act, and wary of him—as the saying went, a starved camel was still bigger than a horse—she could only silently withdraw her power.
Without Gabriel's power sustaining it, given Derek's strength, that Heaven's Fist would not have lasted long even against Li Wei, let alone Mez.
At this point, Lucifer's gaze toward Li Wei turned somewhat strange.
"Li Wei, how exactly did you block Gabriel's full-force attack without suffering a scratch? You should know that even with the power I still possess now, I might not be able to easily withstand Gabriel attacking at full strength."
Lucifer did not hide the loss of his current power from Li Wei at all and asked him with complete frankness.
However, even if Lucifer was weakened, he was still the Lord of Hell. With the power of the Human Realm, there was no need to worry about danger
