In the game's general level system, there is a clear and hierarchical division. So, in terms of judging the rare generals in the new Romance of the Three Kingdoms: Cao Cao's Biography, you need to look at their quality. In the game, from highest to lowest, they are Unparalleled Gold Generals, Rare Gold Generals, Common Gold Generals, Purple Generals, and Blue Generals. Among them, Purple and Blue Generals, in the early stages of the game, mostly serve as fodder for upgrading Gold Generals. And the rare generals are the strongest category of generals before obtaining an Unparalleled one.

Among the rare generals, let's first talk about Guan Yu. His most powerful feature is that after killing an enemy target, he can perform an additional action, although it requires a 4-turn cooldown before it can be used again. This ability to act twice, no matter in which game, is quite advantageous, like having an extra ace card that can be played at any time. However, there is a small prerequisite: you must successfully secure a kill or trigger a critical hit. After all, attacking an enemy general isn't so easy to instantly defeat. Therefore, increasing the critical hit rate becomes particularly important. Fortunately, Guan Yu inherently has a certain critical hit rate. Moreover, choosing Guan Yu as the main damage dealer also has a key reason: the game offers relatively friendly event acquisition channels, making his cultivation slightly easier compared to other rare gold generals. Among all rare gold generals, Guan Yu is second only to Lü Bu. Furthermore, in the Lucky Star Gazing event, you can directly lock onto Guan Yu, which is the most suitable choice for players who want to focus on cultivating him.

Next, let's discuss Cao Cao. As a rare general, at the beginning of the battle, he can increase his highest base attribute (excluding HP and Rage) by 5%. Cao Cao and Liu Bei both belong to the type of supporting heroes who can provide buffs to the team. However, when choosing, it is more recommended to prioritize Cao Cao. The first reason is that on the second day of the server opening at 5 o'clock, the game will give out Cao Cao's body, and the server opening trial will also give out rewards, allowing Cao Cao to star up faster and quickly play his role. The second reason is that Cao Cao and Xiahou Yuan have excellent synergy. When they work together, they can maximize their respective advantages. Moreover, Cao Cao is like a buff mascot, providing almost all kinds of beneficial effects that players desire.

Zhang Fei is also an indispensable presence among the rare generals. His characteristic of getting angry easily makes his rage build up quickly. Combined with his ultimate skill, he is like a powerful bomb in the front line, and the more enemies there are, the more pronounced his advantage becomes, making him very effective in group fights. However, before reaching the 22nd level of military books, Zhang Fei's sustainability is indeed a weakness, as he has almost no sustainability. Zhang Fei's main skill is a sweeping attack that can also inflict debuffs, while his ultimate is an area-of-effect attack. Additionally, after the general reaches +4, he gains some recovery ability, making him well worth focusing on.

There is also Zhao Yun, whose single-ride charge talent is very interesting. At the start of the battle, he can 100% dodge enemy attacks. As his level increases, he will also gain the abilities to be uninterceptable and immune to immobilization, making him like a troublemaker in the crowd, with enemies unable to do anything to him. He has a guaranteed dodge mechanism, but to make this mechanism work continuously, he needs to have a 12th-level military book and critical hit attributes. Otherwise, the guaranteed dodge will be hard to sustain. It should be noted that Zhao Yun's main skill is a straight-line attack, similar to a spearman, while his ultimate is an area-of-effect attack, and his talent focuses on dodging, making him very suitable for tasks like securing treasure chests. However, currently, he does not seem to have any particularly outstanding features, and it may take equipping him with certain items to bring about a qualitative change.

Finally, let's talk about Liu Bei, who is a critical hit mascot. Not only can he heal, but despite his long skill cooldown, the saying "one trick to rule them all" applies, as using his skill well can be very effective in wave battles. Moreover, he is the core of the Shu Han lineup. Although he does not personally fight with swords and spears, he becomes a multiplier for the team's output through his core skill of granting critical hits/critical damage to the entire army. His support abilities are not just for show; they are truly useful in combat. New players can use him to protect Guan Yu as he advances, while experienced players can pair him with Fa Zheng to break shields. Even during the transition period of the lineup, relying on his layer of beneficial buffs, the team's combat rhythm can be stabilized. Additionally, Liu Bei can also be obtained through in-game events, so it is highly recommended to bring him into battle.

About the rare generals in the new Romance of the Three Kingdoms: Cao Cao's Biography, I've introduced these few. In fact, in the stage where there are no Unparalleled generals to obtain, or for players unwilling to spend money on Unparalleled ones, the effect of rare generals is actually greater.
