Chapter 644: 513

Meanwhile, the mighty war machine of the Black Dragon Empire was already in motion. As a nation founded on the principle of war, everything in the Black Dragon Empire was devoted to the service of conflict.

The Undead Army was being produced non-stop, these cheap, or rather, worthless soldiers were a great weapon to exhaust the White Dragon Empire's most valuable assets. Yake didn't need the Undead Army to achieve any substantial gains in battle; their only purpose was to continuously deplete the White Dragon Empire's combat strength.

Yake decided to fight a real winning battle; he wanted to fully drag down the White Dragon Empire; he intended to leave them with no way to turn the situation around!

Whenever he thought of crushing the Imperial City of the White Dragon Empire, witnessing Long Yi humbly crawling at his feet, Yake felt an uncontrollable urge to burst into triumphant laughter.
