Pre-dawn at the South Gate of Sun-Beol. Smoke hangs blue over blackened oak and iron as the city prepares for Tabi’s first official siege binding.

Tabi begins the practical inspection while the soldiers keep whispering.

General Sang Eo-jin arrives and asks for the actual rule Tabi intends to carve into the gate.

Tabi chooses the south gate clause and explains its limits before binding.

Tabi performs the south gate binding. The rule turns from words into force.

The first test proves the gate opens for a properly marked imperial soldier.

A civilian cook tries to pass and the new clause refuses her, making the cost immediately visible.

The next test proves the clause will reject even an ally if the exact wording is not satisfied.

The south gate test ends. Tabi’s control holds in public, but Madam Ho sees the strain.

Day two shifts to the river-port, where wet stone, chains, and the iron lattice gate guard the city’s supply route.

Tabi studies the river-port and asks what the gate must allow. The answer is complicated by moving water and human deception.

Tabi chooses a time-limited clause for the river-port, balancing the risk of stolen symbols against the limits of one-clause magic.

Tabi binds the river-port gate. The magic takes on the color of river light and gold script.

A loyal supply skiff approaches under the correct standard and the river-port admits it.

The engineers release a decoy raft without the proper standard. The river-port rejects it violently.

Soldiers cheer Tabi for the first time. The praise lands on him like another kind of pressure.

Night falls. Tabi returns to his narrow assigned room above the archive, carrying the weight of two successful bindings.

Sang Eo-jin arrives at Tabi’s room without guards, carrying wine.

Sang places wine between them and makes clear he is not there to celebrate Tabi’s success.

Sang reveals that he knew Tabi’s mother by name and that her life was larger than Tabi was told.

Sang describes Yeon Da-rye as a doorman whose precision was feared and respected. Tabi tries not to reveal how much the information matters.

Sang says Yeon once bound a door for him that he never got to use, forcing Tabi to choose his next question carefully.

Tabi asks what the old bound door was for. Sang gives one plain answer and no explanation.

Sang leaves before Tabi can decide whether to challenge him. Tabi remains with the wrapped kitchen door and a new uncertainty.
