Shall Seal the Heavens novel?
You are looking for I Shall Seal the Heavens, written by Er Gen between 2014 and 2016 and translated in full by Deathblade on Wuxiaworld. The title is 我欲封天, literally I wish to seal the heavens, and sealing the heavens is the ninth technique of the lineage its protagonist inherits.
You are almost certainly looking for I Shall Seal the Heavens.
The missing "I" is not a mistake so much as an echo. The phrase that sticks in people's heads is the book's tagline — my fate is to seal the heavens like a demon — and the tagline does not have a pronoun in it. Somebody remembers that, half-remembers the cover, and searches for the fragment.
The title, decoded
The Chinese is 我欲封天. Three characters and a subject.
我 is I. 欲 is want, wish, intend — the same character as in desire, and the one that makes the title slightly ominous, because wanting is not the same as being permitted. 封 is to seal, to close off, to enfeoff; in the compound 封天 it is the sealing of heaven, and it carries the older sense of a boundary being drawn rather than a lid being put on. 天 is heaven, or the sky, or the order of things, depending on which sentence it is in. Where an English translation writes the order of things, the glossary writes the heavenly dao, and the two are the same claim at different temperatures.
So the title is not "I will defeat heaven." It is closer to "I intend to seal heaven," which is a stranger and more interesting claim: not to overthrow the order but to close it, to put it under a seal, the way the lineage's techniques seal everything else.
What sealing the heavens means inside the book
The protagonist inherits the legacy of the Demon Sealers, a lineage that runs eight generations before him. Each generation contributes a hex — 禁, a forbidden art — and the ninth is the one the title is named after.
In practice the hex works like a jurisdiction. When Meng Hao finally uses it against Allheaven, a character for "seal" appears in his palm and everything within reach is drawn in: natural laws, magical laws, entities, wills. It is not a blast. It is an arrest, closer to the older idea of heaven's will being something you can put on trial than to any lightning attack in the genre. The final measure of him, then, is not his cultivation base: it is what he is allowed to arrest.
That is why a title about sealing the heavens reads oddly to new readers and perfectly to people who have finished the book: no one reads a cultivation level list and expects the last entry to be an arrest. The novel is not about a man who wants to rule heaven. It is about a man who wants heaven to stop moving.
The publication facts
Er Gen is the pen name of Liu Yong, who studied English at university in Heilongjiang and became one of Qidian's platinum authors. I Shall Seal the Heavens is his third novel, after Renegade Immortal and Pursuit of the Truth.
It is complete, which in a genre this size is a genuine selling point. The wiki bibliography gives ten books and 1,613 chapters plus three side stories; Wuxiaworld's page for the series shows 1,620 chapters, which is the same book counted with the extras included. Deathblade's translation ran to the end, and the final chapter carries his sign-off.
That matters more than it sounds. This genre is full of novels whose English versions stop in the middle, and a reader who starts one without checking is taking a real risk. This is not one of those. The last line is reachable.
The sequels that are not sequels
Er Gen kept writing, and the later books share a universe with this one without continuing it. A Will Eternal, A World Worth Protecting and Beyond the Timescape are separate stories with separate protagonists; they use the same cosmology and the same vocabulary for realms, which is why wikis group them together and why readers argue about whether that makes them a series.
It does not, in the sense that matters for reading order: the dao is shared, the plot is not, and you can start with any of them. Starting here is the common choice because it is the one with the largest English readership and the most complete reference material.
If you actually wanted a different book
Two possibilities.
If you were thinking of a Chinese novel about sealing, there are several where 封 appears in the title, and none of them are this one — the search results will be full of them, most of them much shorter and much less translated.
If you were thinking of the phrase as a line rather than a title, it appears in the text as a vow, and the vow is the thing the whole 1,613 chapters are built to pay off. That is worth knowing before you start: the book is longer than its promise, and the promise is kept.
The questions people ask
Is it I Shall Seal the Heavens or Shall Seal the Heavens?
The published English title is I Shall Seal the Heavens. Searches that drop the pronoun are common because the phrase is usually quoted from the book's tagline, which reads my fate is to seal the heavens like a demon. Either way, the same novel comes back, and there is no second book with a shorter name.
Who wrote it and how long is it?
Er Gen, whose real name is Liu Yong. The novel ran on Qidian and is complete: 1,613 chapters plus three side stories in ten books, or 1,620 chapters counted with the extras, which is the number Wuxiaworld shows. Deathblade's translation finishes with a translator's note in the last chapter.
Where can I read it?
Wuxiaworld carries the licensed English translation and lists the series as complete. That is the version most readers quote, and the one whose chapter numbers every wiki and forum uses, so it is worth starting there rather than on an aggregator with different numbering.
Reading order around it
The franchise has a natural entry point and a natural second step. If this book is the entry point, the second is whatever Er Gen wrote next, because the cosmology continues and the vocabulary carries over.
What does not carry over is the tone, or the cultivation stages the reader had to learn to get through this one. Later books lean harder on comedy and are quicker to let their protagonists be ridiculous, and a reader who comes to them expecting the same melancholy will find a different animal. That is not a fault, but it is worth knowing before you buy a thousand chapters of it.
