(One heroine + no System + unconventional body-refining cultivation)
After transmigrating into a cultivation world, his parents have vanished, his aptitude is poor, and his hopes of cultivating are slim.
He awakens a mysterious orb, gulps down pills, tempers his battle body, and joins the Battle Heaven Sect.
He enters the inner sect, cultivates the Vajra Glazed Dharma Body, and challenges opponents above his level.
He forms a Golden Core and becomes invincible beneath the Nascent Soul realm.
He masters four Dharma Bodies and shocks the world by fighting a Spirit Transformation cultivator with a Golden Core.
He breaks through to Nascent Soul, enters Spirit Transformation, battles the Heavenly Dao, shatters the void, and breaks a hundred thousand years of shackles on heaven and earth.
He ascends to immortality and becomes the Battle Heaven Emperor, a body cultivator.
The legendary version:
The Heavenly Dao has imposed its shackles, making ascension impossible.
Do you know who became the first person in a hundred thousand years to attain the Dao and ascend? The Battle Heaven Emperor, from the Battle Heaven Sect in the Western Regions.
He focused solely on refining his body and mastered all four of the Battle Heaven Sect’s Dharma Bodies. At Foundation Establishment, he could fight Golden Core cultivators; at Golden Core, he could annihilate Nascent Soul cultivators. Most astonishing of all, he fought Spirit Transformation cultivators while still at Golden Core.
In the end, he condensed a Nascent Soul, entered Spirit Transformation, shattered the void with his physical body, and ascended to immortality.
His surname seems to have been Chen, and he came from the Chen family, a Foundation Establishment clan...
