Cultivation, not a level bar
Tu vi grows by the game hour and the game day you spend seated. Every zone has its own linh khí density, so where you sit matters as much as how long.

Last life: overtime.This life: level up.
You wake up in Thanh Khê Village with one thing to your name: a spirit root rolled by heaven. Sit and take in linh khí, break through your bình cảnh, ride a flying sword over the sea of clouds, and take on fifteen Yêu Vương. Free, right in your browser.
Internal test: only invited accounts can log in.
Cửu Thiên Huyền Giới is a top-down pixel cultivation RPG. It plays slowly. Tu vi comes from seated meditation counted in game hours and days, fighting is for materials, and breakthroughs happen when you decide you are ready.
Tu vi grows by the game hour and the game day you spend seated. Every zone has its own linh khí density, so where you sit matters as much as how long.
Heaven rolls your root at character creation: Kim, Mộc, Thủy, Hỏa or Thổ, and one roll in a hundred is Hỗn Độn, which fits every element. Forty công pháp sort by element, and they carry your thuật, aura and VFX with them.
Playing alone, one game day is 16 real minutes. Online it follows the real clock: the light, the shops, the villagers and the herbs turn with the hour.




Nothing breaks through on its own. You sit, you choose, and a wrong choice costs you tu vi, materials or the fight itself.
Sit and take in linh khí. The gain is counted in game hours and days, thick linh khí zones pay more, and longer sessions pay a bonus.
At a bình cảnh you pick: push through, or consolidate and take the next one later. One deed per bình cảnh adds fifteen percentage points and a đốn ngộ.
Before each major step comes a thiên kiếp: a survival fight, not a dice roll. Clear it and your health, mana and thần thức rise, and your lifespan stretches.




Lifespan comes with the realm: a hundred years as a mortal and through Luyện Khí, two hundred at Trúc Cơ, four hundred at Kết Đan. When the years run out you can huyết tế tái sinh: drop one major realm, live on, and pay five more years.
One world, two ways to cultivate. The blood path hits harder and cannot fly, so every route has a walking way round.
The default path. You cultivate art that fits your root, break through with linh thạch, and ride a flying sword: the sky routes to the islands and the relics open up.
You start from Xích Thổ. Instead of linh thạch you bathe in blood to climb the Huyết Cơ ladder, and you trade flight for a tougher body and heavier hands.

ThổYour root sets the element of your cultivation art, your aura and your VFX. Hỗn Độn fits every element and turns up in one roll out of a hundred.
From Thanh Khê Village out to the sea: seven towns and cities, twenty-four wild zones, five sect mountains and fourteen regions. Walk, take the ferry, or light a teleport array.
Linh khí density sets how fast you cultivate, herbs come back on a daily clock, and ore and beasts belong to their zone. Hidden linh mạch sit under the ground; you tap one by building a Tụ Mạch Trận on it.
Four factions keep their own renown with you: Thanh Vân Môn and Huyết Sát Tông, plus Thiên Khu Thành and Vân Thủy Thành on the trade roads. Pass the exam at the gate, run the task board, earn cống hiến, enter the Đại Bỉ, and farm the bí cảnh that opens by weekday.
Relic sites and inheritance grounds open for a few days and close again. Once inside you are competing for the same herbs, so go early or go armed.
Xích Viêm. A lava chasm, two narrow bridges, and a dais that stays open for five days.







Lỵ Lực scrapes the ground for 0.6 seconds, marks a red lane and charges; miss it into a tree and it is stunned. Quỷ Diện Hầu snatches up to 3 items and runs 12 tiles. Mộc Yêu stands as a tree until you come within 2 tiles. Âm Hồn walks through walls at night and fears torches. Lộc Thục heals its whole pack, so it goes down first.
Melee combos, element thuật, ranged phi kiếm. Enemies pick targets off a threat table, elites bring their own attacks, and boss health scales with the size of the party in front of it.
Fifteen Yêu Vương come in three stages: six you meet first, five more at Luyện Khí and Trúc Cơ, and four past Kết Đan. Three world bosses open to everyone at 12:30 and 20:30 Vietnam time every day, with the loot split by contribution.
Four crafts, each gated by a phẩm exam before it opens its higher tiers. Materials come from beasts, herbs, veins and the secret realms.

From Phàm to Cực. The grade sets the item's stat budget and how many lines it can roll: none at Phàm, up to four at Cực. Tẩy luyện re-rolls what landed, and you can lock the lines you want to keep.
Linh thạch is the coin. Shops pay forty percent and take at most ten thousand a month, Vạn Bảo sells the rare lines, caravans move stock between towns, and consignment sells for you. Online adds a shared market that takes five percent.
The border shows the grade: grey Common, green Low, blue Mid, purple High, red Supreme.
Thuật sort by element, Kim, Mộc, Thủy, Hỏa and Thổ, then come the 54 gifts each breakthrough opens.
Meet other cultivators in the wilds, form a party, trade on the shared market, found a đạo minh, climb the tower and race the season.
Every wild map splits into three khu and you pick one. Parties hold four people. Towns, cities and sect grounds are An toàn and refuse a fight; out in Dã ngoại, Tranh đoạt and Hỗn loạn you can attack once you leave Hòa bình mode. A kill costs the victim ten percent of their linh thạch and marks the killer: red names draw the guards and a higher price, black names also show on the map and post a bounty.
The shared market takes five percent and gives you a linh thạch kho and a parcel box. Auctions take real bids. Đạo minh are founded by players, twenty to forty of them, with roles, a fund, chat and a PK shield.
Ảnh Đấu pits you against the shadow of another player, and each win lifts your rating. A season runs one month, and its rewards are titles, footprints and auras: nothing that touches your power.
A tower you climb alone. Floors scale as you go and every fifth one holds a tàn ảnh. The modifiers change weekly and the ranking pays out at the end of it.
No event gates by realm: Phàm Nhân to Giả Anh all join. Event enemies stand at a fixed level, the game converts blows both ways by your realm, and the reward follows your own realm.

Three times a day, linh khí everywhere rises by half for an hour. It is the best hour of the day to sit and cultivate.
No sign-up. Sit down anywhere when the hour comes, in your cave or out in the wilds, and the extra tu vi adds itself.

Elders lecture twice a day for 15 minutes at the Thanh Vân hall, the Huyết Sát hall and the West Market tea house.
Press F for Thiên Hạ, open the Events tab, pick Dao Lecture and press Go. Stand within 4 tiles of the elder, or sit nearby, for 10 minutes.

One secret realm opens twice on each weekday. On Sunday all six open and rare drops come at one and a half times the rate.
Press F, open Events, pick today's realm and press Show map to reach the teleport array. Go in, clear the enemies and open the last chest.

Kim Sí Đại Bằng on the Trung Châu plain, Giang Giao on the Đông Hải cliffs, Tứ Dực Ưng Vương on the outer Đông Hải islands. Each fight lasts 15 minutes and the boss's health grows with up to 20 fighters.
Press F, open Events, pick the boss and press Show map. Deal 5% of the damage to earn a chest, once a day. The boards rank each fighter and each sect.

Three waves march on Hạ Khê Trấn and Xích Thổ Trại, 6 minutes apart. The last is led by a Yêu hóa leader.
Khí tu hold Hạ Khê Trấn, huyết tu hold Xích Thổ Trại. Hit 3 enemies to be sure of a share. Let one within 1.5 tiles of the point and the chest pays half.

One tournament a week. On Sunday at 20:00 Vietnam time the server draws the Thanh Vân Môn disciples who signed up that week and runs a knockout. Each bout uses the snapshot of you taken at sign-up and ends in a knockdown, a ring-out or the time limit.
Outer disciples and up go to the Thanh Vân Môn main hall and pick Enter the Grand Tournament before Sunday 20:00. The snapshot keeps your stats from sign-up, so break through first. With fewer than 2 entries the week is skipped. Rewards pay once, the next time you log in. Pick View the Grand Tournament board for this week's entries and last week's results.
Each season lasts three months with one theme: Hắc Mộc rising, the beast stampede, the Đông Hải flood, and the blood moon over Xích Thổ.
Each week the tower rolls 1 or 2 modifiers: Frenzy, Revival, Inferno, Scattered Qi, Iron Wall, Splitting. Titles wait at floors 10, 20, 30 and 50.
