In the new Romance of the Three Kingdoms: Cao Cao's Biography, the general Cao Ren demonstrates quite a notable strength. From the perspective of troop characteristics, Cao Ren belongs to the short sword infantry, with an attack range of only 1 grid. However, he possesses 4 grids of mobility, which to some extent grants him a relatively flexible battlefield positioning capability. Therefore, in many current formations, Cao Ren can still be included.

Cao Ren's innate talent, Iron Wall, at the beginning of the battle, applies the powerful effect of growing stronger against stronger opponents to himself, and this effect lasts throughout the entire battle. A key point is that it cannot be dispelled, allowing Cao Ren to perform relatively stably in various complex battle situations. Looking at his active skills, first is Fortify and Guard. Once this skill is activated, it provides a guard effect to himself and also transfers the Endurance effect to the surrounding friendly units, with this beneficial state lasting for 2 turns.
When the skill reaches level 2, it additionally applies the Impregnable Fortress effect, also lasting for 2 turns, further enhancing defensive capabilities. However, to activate this level, the conditions of the general reaching 5 stars and the military book upgrading to level 7 must be met. At level 3, the cooldown time for the strategy will be reduced by 1 turn, requiring the general to reach 6 stars and the military book to reach level 12. At level 4, the guard range will be expanded to a diamond shape of 2 grids, with the activation condition being the general reaching 8 stars and the military book reaching level 17, allowing him to better protect his teammates in team battles.

The rage skill, Wrath of Heaven, after consuming 200 rage, can cause blade damage. Especially when the target has the effects of Slow Troops I, II, or III, it will also inflict additional true damage equal to 60% of Cao Ren's defense. When the skill level is upgraded to 2, the inflicted damage increases to 185%, with the activation condition remaining the general reaching 5 stars and the military book reaching level 7.

Another active skill, Eight Gates Golden Lock, inflicts 90% melee infantry sword damage to all enemy units within one grid around Cao Ren and applies the Slow Troops II effect, lasting for 2 turns. When the skill is upgraded to level 2, the damage increases to 95%, with the activation condition being the general reaching 5 stars and the military book reaching level 7. At level 3, the cooldown time for the strategy is reduced by 1 turn, requiring the general to reach 6 stars and the military book to reach level 12. At level 4, the inflicted damage further increases to 105%.

Regarding the general's attribute skill, Solid Shield, it allows Cao Ren's overall attributes to increase by 1.5%. As the skill level improves, the benefits it brings also increase. At level 2, the overall attributes are increased to 2%, and the maximum HP is also increased by 2%, with the activation condition being the general reaching 5 stars and the military book reaching level 7. At level 3, the overall attributes are increased to 2.5%, the maximum HP is increased to 2.5%, and the block chance is increased by 7%, requiring the general to reach 6 stars and the military book to reach level 12 for activation. At level 4, the overall attributes are increased to 3%, the maximum HP is increased to 3%, the block chance is increased to 8.5%, and an additional 12.5% reduction in critical damage is provided, comprehensively enhancing Cao Ren's survival and combat endurance capabilities.

From the perspective of the general's five-dimensional attributes, Cao Ren has a high command value of 88. Thus, when receiving weapon damage, the damage reduction is calculated based on the difference between the defender's command and the attacker's might. For every 1 point increase in the difference, the final damage received decreases by 0.25%. This means that Cao Ren naturally has an advantage in defending against weapon attacks. Additionally, his might value is 86, which is relatively high among many generals, enabling him to be fully capable of participating in early-stage battles.

Now, everyone should have a clear understanding of how Cao Ren performs in the new Romance of the Three Kingdoms: Cao Cao's Biography. Therefore, in the early stages, you can completely consider Cao Ren as a key development target. Although his range is a bit short, his strength and numerical values are still considerable, and his output is still usable.
