第1章 下界护道？

Protector of the underworld?

Lu Ming traveled to a fantasy world and signed in to the check-in system, embarking on a passionate and invincible journey. In less than a century, Lu Ming ascended to the Chaos Realm and became a dominant overlord. It was thought he would continue his pursuit of the Great Dao, but... As his cultivation level improved and the system's check-in rewards became increasingly better, he decided to lay low.

With daily sign-ins, Lu Ming's cultivation gradually improved. When he reached the Ancestral God realm, the system finally found an opportunity to trigger a task, and the task turned out to be: to protect the lower realm!

Dimensionality reduction attack? Don't blame me, it's the system that made me do it.

Lu Ming: I walk the world as a protector, witnessing all the ups and downs in the world, and slaying all the invading enemies!

(Invincible article! Although the protagonist still has a realm in the early stage, it is also a dimensionality reduction attack, and it won’t be long before the realm is no longer needed)

陆铭穿越至玄幻世界，并绑定签到系统，从此开启了热血的无敌之路。不到百年时间，陆铭便飞升混沌界并成为雄踞一方的霸主，本以为他会继续追求大道，然而。。。由于随着修为提升，系统签到奖励也越来越好，他决定躺平了。
随着每日签到，陆铭修为逐步提升，当他达到祖神境界时，系统终于找机会触发任务了，而任务竟然是：下界护道！
降维打击？别怪我，系统让做的。
陆铭：我，以护道者身份行走世间，看尽世间风云，斩尽来犯之敌！
（无敌文！前期主角虽然还有境界，但也是降维打击，而且过不了多久就不用境界了）
