"Everyone, let's come together! Today, no one can kill Han Fei alone. I think it's enough if we can kill him together."
At this moment, Han Fei hadn't fully activated his Great Dao. The reason why he could completely refine the Heavenly Dao Jade Marrow Bone was firstly because he had absolutely sufficient resources, secondly because he borrowed the power of the Heavenly Dao in the Demon Realm, thirdly because he studied the green jade stone bridge, and fourthly, because the Supreme Divine Technique of the human race was imperceptibly improving his strength.
With these four opportunities, he could completely refine the Heavenly Dao Jade Marrow Bone at the Dao Proving Level. After refining this bone, with his physique and combat power, he would have enough combat power to fight a peak-level Carefree Level cultivator alone.
Therefore, although so many Monarchs were attacking him, he could still resist them.
