Some years later, Lê Thận joined the rebel army of Lê Lợi, where he quickly rose in ranks. Once, the general visited Lê Thận's home. Lê Thận's house lacked lighting, so everything was dark. But as though it was sensing the presence of Lê Lợi, the blade at the corner of the house suddenly emitted a bright glow. Lê Lợi held up the blade and saw two words manifesting before his very eye: "Thuận Thiên" (Will of Heaven). With Lê Thận's endorsement, Lê Lợi took the blade with him. One day, while on the run from the enemy, Lê Lợi saw a strange light emanating from the branches of a banyan tree. He climbed up and there he found a hilt of a sword, encrusted with precious gems. Remembering the blade he found earlier, he took it out and placed it into the hilt. The fit was perfect. Believing that the Heaven had entrusted him with the great cause of freeing the land, Lê Lợi took up arms and rallied people under his banner. For the next few years, the magic sword brought him victory after another. His men no longer had to hide in the forest, but aggressively penetrated many enemy camps, captured them and seized their granaries. The sword helped them push back the enemy, until Vietnam was once again free from Chinese rule. Lê Lợi ascended the throne in 1428, ending his 10-year campaign, and reclaimed independence for the country.
