The invader was so strong that the king had to ask envoys to search for those who could fight against the enemy. When hearing the envoy's voice, the child began asking his mother to call the envoy. The man came in and was surprise to hear that the child wanted to have a horse, an amour and a rod all made from iron to fight for the country's peace. Immediately he returned to the court and reported what had happened to the king and then all the requirements of the child in Giong Village were fulfiled through days and nights as the king's order.

Suddenly the ironed rod was broken but he continued struggling by rooting up all the bamboo groves and used it as his former weapon. The invader's willing was absolutely broken. They all shattered and trampled on others to run away. The man ran after them to Soc Son mountain. At last he reached the top of the mountain then put off his amour and finally flew into the heaven together with the horse.
