This article presents a technical-fictional prototype of travel along the chain of neighboring universes A₁, ₁ A₁, ₂ A₁, ₅ based on the Infinite-Dimensional Multiverse Model (IDM). The text is a strict extrapolation of IDM postulates and supplements the prognostic article in the series. The key paradox is substantiated: the distance to a neighboring universe is undefined in three-dimensional space, making conventional "flight" impossible. The only means of travel is a quantum breakthrough between branes, requiring Planckian energy (10^19 GeV) and generators of planetary or stellar size. A step-by-step procedure is described in detail: identification of the w₁ axis, measurement of interaction intensities, breakthrough creation, stabilization, and navigation. The journey consists of a series of jumps between branes, not motion in the conventional sense — the ship remains stationary until the breakthrough. Possible universe types are classified by "hospitality": from habitable (constant deviations 10^-3-10^-2) to sterile, vacuum-unstable, and singular. Specific scenarios of constant values and expected conditions are provided for A₁, ₁ A₁, ₅. Demarcation from related concepts is carried out: academic brane models (Braneworld Hyperdrive, Green, Kabat et al. ), science fiction (Baxter, Stewart), and Everettian branches (many-worlds interpretation). It is shown that the proposed mechanism (physical movement between branes via breakthrough) has no direct analogues.
