With the whole of the Mongol invasion force at his very heels, Moon Bin Kim and his fetching servant girl are on a desperate flight to his father's stronghold at Ghu Zhu Palace. On the road, Moon Bin will encounter new bloodcurdling minions of the enemy, strange allies, and more keys to the startling time-displacement phenomenon that sent this ordinary high school student back in time to 13th Century Korea!

Upon receiving the package of his wife's severed head from the Mongols, Kim Kyung-Sohn burns the box. When the troops at Ghu-Zhu Palace get word of the Mongol troops approaching, Kim Kyung-Sohn decides to take matters into his own hands and face the troops...all alone. Sali Tayi is stunned by Kim Kyung-Sohn's lone presence. The strength of his presence, though, is not merely that of any ordinary man--he fights like an army of thousands!

Winning notice in the upper ranks of the Mongol Army, the slave Moon-Bin--or rather the son of the great General Kim Kyung-Sohn in the reality that Moon-Bin now finds himself--may once again be reunited with the beautiful and compassionate Atan Hadas, who has becoming increasingly disgusted with the decadence and carelessness of the Mongol high command. But Moon-Bin might also soon come to the attention of General Tali Sayi, a man who has sworn to destroy the Kyung-Sohn family!

Having been promoted in the field of battle, Moon-Bin now realizes he can't fight against his own countrymen and deserts the Mongol army, only to be caught by Sali Tayi. But the fluid of time begins pulling him again toward his own era before he is able to avenge his 13th-century family, begging questions of where in time his heart truly belongs...especially as his affection for Atan Hadas only continues to grow amid the bloodshed and tears.

Once again in the command of men, civilian militiamen as they are, Moon-Bin demonstrates deft leadership in driving away Mongol soldiers. However, his popularity is growing and one of the fleeing soldiers recognizes him. It isn't long before Sali Tayi hears of the re-emergence of the man who has now become his most hated foe. And that hatred may doom any man who decides to follow the young, lonely, time-traveling hero.
