Soul devices are actually unknown to many players. The introduction of the soul device system in the Soul Land hunting world will let everyone know that soul devices are artificial devices driven by soul power. Their core arrays can enhance the output of soul masters. Among the numerous soul devices, according to their functions and characteristics, most can be divided into three major categories: melee soul devices, ranged soul devices, and fixed-configuration soul devices.

Melee soul devices, commonly seen as various weapons, play a key role in close combat. They are important auxiliary equipment for soul masters in close-range confrontations, greatly enhancing the attack power and lethality of soul masters in close combat, giving them an advantage in such scenarios. Ranged soul devices, on the other hand, have the ability to attack from a distance. This feature allows soul masters to attack distant targets without having to get close, enabling them to strike enemies from a safe distance and effectively expanding their attack range.
Fixed-configuration soul devices are a new type of soul device carefully developed by Fan Yu. Their power is typically at least one level higher than that of other soul devices of the same grade. For example, the ninth-grade fixed-configuration soul cannon shell, when used in conjunction with a ninth-grade soul cannon, can even strike across half a continent. For ordinary titled Douluos, encountering such a cannon shell head-on would almost certainly result in death, making the ninth-grade fixed-configuration soul cannon shell acclaimed as the most destructive ninth-grade soul device.

Due to its extremely high production difficulty, it is no less challenging to make than a ninth-grade soul device. Additionally, since it is a single-use item, there is no need to consider the device's ability to withstand the burst power during its use. There are also a variety of other types of soul devices, such as storage soul devices, which have the function of storing items. A typical example is the Twenty-Four Bridges Moonlit Night, a belt evenly embedded with 24 jade stones, each providing 1 cubic meter of storage space. However, as there is no air inside, it cannot be used to store living things. Flying soul devices can be worn, and by injecting soul power, they grant the ability to fly, expanding the mobility and activity range of soul masters.

Defensive soul devices provide defensive capabilities, such as shields, wearable armor, and protective light barriers over arenas. They offer varying degrees of protection to soul masters in battle, reducing the damage they receive. Auxiliary soul devices, like milk bottles, can assist soul masters by helping them recover stamina or soul power. There are also interference bombs, which can break through linked defensive soul device shields, playing a unique tactical role in specific combat situations. The limitation of Battle Armor is that it requires a high amount of soul power and mental strength; only those who reach a certain value can equip it. Although the soul power amplifier does not have a clear soul device grade, it has a unique function: any soul device equipped with it can increase its own grade by one level, except for ninth-grade soul devices.
The soul paralysis ray is rectangular, about one foot long, and is a specialized arm-mounted offensive soul device. When a soul master is hit by this device, all soul masters below the Soul King realm will be affected to varying degrees. The extent of the effect varies based on the soul master's cultivation level. For a Soul King, being hit would result in about one second of paralysis, while for a Soul Ancestor, the paralysis could last more than two seconds. Even a Three-Ring soul master, if hit, would be paralyzed for three to four seconds.

The six-barrel small soul cannon is one of the most powerful among fourth-grade soul devices. Its most prominent feature is its proficiency in covering fire, making it one of the most favored soul devices by the military. Imagine if ten fourth-grade soul masters, each equipped with a six-barrel small soul cannon, simultaneously covered a specific area with fire; their powerful firepower could suppress thousands of opponents. However, this soul device has both significant advantages and disadvantages.
Its advantages are its strong burst power, wide coverage, and high attack power, allowing it to quickly deal massive damage to enemies in battle. However, it also has a potentially fatal flaw: the consumption of soul power is extremely high. A fourth-grade soul master using a six-barrel small soul cannon can only sustain it for up to five minutes before needing to stop and rest to recover the consumed soul power, which significantly limits its sustained combat capability.
This concludes the introduction to the soul device system in the Soul Land hunting world. The soul devices mentioned here are some of the basic ones currently available, and the overall system has not been fully updated yet. The ones recommended above are quite good, and you can also check the game later to see which other soul devices are useful.
