It was precisely because the gap between level twelve and level eleven was so big that Zhao Feng couldn't help but not upgrade to level twelve after occupying the underground world, deceiving the vast majority of players and making the vast majority of players believe that the underground world occupied by Zhao Feng was not as big as a small map.

And now, Zhao Feng can justifiably be promoted to level twelve, and even after he is promoted to level twelve, he can quietly cultivate another level twelve-level sub-hero.

Not to mention the various upgrade requirements, Zhao Feng was promoted to level twelve, and through the competitive achievement list, Zhao Feng knew that he was the nineteenth player in the entire game and the third twelfth-level player of the cemetery clan.

After the upgrade, Zhao Feng is first of all upgrading skills and sub-skills.

Level 12 purple players get two skill points at the first level, and Zhao Feng adds four points to the rank of major general (one skill point can be obtained when the rank of second lieutenant, major, brigadier general, and major general), a total of twenty-eight points, and four skill points for expert-level skills, Zhao Feng can learn seven expert-level skills, and the average twelve-level player can only learn six expert-level skills, which is an advantage of Zhao Feng.

However, with the increase in the ranks of the majority of players, this advantage will not be maintained for too long, at least, among the current nineteen twelve-level great lords, there are four with the rank of major general, eleven with the rank of brigadier general, and one colonel and one lieutenant colonel remain.

Zhao Feng's seven skills are spiritualism, wisdom, earth magic, intelligence, magic, tactics, and offense.

Each expert-level skill, you can open three sub-skills for heroes to choose, only one of them can be selected, if you have the skill A level or above talent specialty, you can choose one more, if you can upgrade to level fifteen, the skill is upgraded to the master level, and three more powerful sub-skills will be opened.

And Zhao Feng now has to choose his seven sub-skills.

Wisdom Sub-Skills:

Magic Mastery: Increases the hero's magic spell slot, increasing the amount of magic the hero can master by 50%.

Tower Defense Mastery: When a hero is stationed in a magic tower, the effects of Intelligence, Mana, Mysticism, and Eagle Eye skills are increased by 50%.

Tower Attack Mastery: When a hero is stationed in a magic tower, the effect of the four magic skills is increased by 50%.

The three sub-skills of wisdom are not very useful, although the hero has a limit on the number of magic (and the level and quality have the same impact on skill points), but the twelfth-level purple hero can learn twenty-four magic, and the number of magic is sufficient, as for the defense and attack of the magic tower, which player will let a twelve-level hero not lead soldiers but go to defend the magic tower during the defense of the city?

Zhao Feng casually chose a magic master.

Spiritist Sub-Skills:

Necro Witch Transformation Mastery: You can save the corpses of the enemy's Ninth or higher spell class corpses killed in battle, and then transform them into corpse witches of the same level in your own Necro Witch Barracks. Each time a corpse is saved, it costs 100 Soul Energy (Heroes from the Witch only need to consume 50 Soul Energy to choose the Soul Transformation Mastery).

Note: The spell class is different from the law class, the law class refers to the class that can freely learn the hero's magic, while the spell class includes all the law class and some regular class, such as the human sacrifice and the cemetery corpse witch are all spell classes, but not law classes

Black Knight Transformation Mastery: You can save the corpses of cavalry classes above level 9 that are killed by the enemy in battle, and then transform them into black knights of the same level in your own Black Knight barracks. Each time a corpse is saved, it consumes 100 points of conjuring energy (heroes from the Black Knight only need to consume 50 points of conjuring energy if they choose the Black Knight to transform into mastery).

Dark Dragon Transformation Mastery: You can save the corpses of dragon class 11 or above that the enemy died in battle, and then transform them into the same level of dark dragon in your own dark dragon barracks. Each time a corpse is saved, it consumes 100 points of Spiritualism Energy (heroes from the Dark Dragon only need to consume 50 Spiritist Energy when they choose the Dark Dragon Transformation Mastery).

Expert-level spiritualism, consuming 4 points of spiritualism energy can convert the enemy's dead corpse into a fourth-level skeleton soldier, but the fourth-level skeleton soldier, let alone a twelfth-level player, is useless for eighth-level or nine-level players, so in view of the chicken rib effect of high-level spiritualism, the spiritualism sub-skill gives cemetery players a chance to obtain high-level soldiers.

In terms of actual effect, the effect of these sub-skills is not strong, because the conjuring energy of a purple name twelve-level player is just 100 points, so if you want to save a corpse, you must obtain it in the first battle of the day, otherwise, any battle consumes a little conjuring energy, and this sub-skill will be invalid. And after obtaining the corpse, there must be a barracks of the department, for example, Zhao Feng does not have a corpse witch and a bone dragon barracks now, so it is useless for Zhao Feng to choose the corpse witch mastery and the dark dragon mastery, so Zhao Feng chose the black knight transformation specialty.

Although the actual effect of the Spiritualist sub-skill is not ideal, if it is done correctly, it can occasionally get surprises. For example, when a player hits a boss while doing a difficult task, he can wait until the next day to fight, then he can get the corpse of a high-level soldier, and if he is lucky, he can get a level 13 soldier, which will be refreshing.

Intelligence Sub-Skills:

Intelligence Saving: If the hero does not consume or lose any mana in a month (four days in real time), he or she can store up mana and release it in the next battle, after which the mana will be doubled.

Intelligence Overdraft: Overdrawing Intelligence in a battle will double the hero's mana in the battle, but the mana will be 0 for the next month, and it cannot be restored in any way.

Intelligence Leadership: Increases the knowledge of the French troops in the hero unit, and the added value is 5% of the hero's own knowledge.

Intelligence accumulation skills, there is no aftermath after use, but there is a preparation time to activate the skill, in case the player encounters the ghost of the cemetery clan in a certain battle and is absorbed by the magic, the wisdom accumulation will be wasted. On the other hand, although the intelligence overdraft can be doubled at any time, but after a month of not being able to use magic, the vast majority of players will choose the intelligence overdraft, because the intelligence overdraft is more flexible than the intelligence savings. Zhao Feng chose the third sub-skill intelligence leader, because he has Hunter, it is foreseeable that Zhao Feng will have a lot of vampire mages, among the various legal classes, the advantage of vampire mages is that they can learn four types of magic, and the disadvantage is that their knowledge attributes are low. Assuming that Zhao Feng's knowledge and strength can be stacked to 40 points, he can add two points of knowledge to the vampire mage, which is 20 mana points. If Zhao Feng leads 100 vampire mages, it will be 2000 mana points, even if the vampire mage's magic cannot be upgraded, and the magic effect is not strong, but it can't stand up to a large amount.

Mana sub-skills, like intelligence, are also savings, overdrafts, and leadership.

However, Zhao Feng did not choose the magic leader, but chose the magic overdraft, because the vampire mage's strength value was too low, and it didn't make sense to add one or two points.

Earth Magic Sub-Skill:

Level 1 Earth Magic Mastery: Increases the hero's Level 1 Earth Magic base magic by 40%.

Level 2 Earth Magic Mastery: Increases the hero's Level 2 Earth Magic base effect by 20%.

Level 3 Earth Magic Mastery: Increases the hero's Level 3 Earth Magic base effect by 10%.

For these three sub-skills, Zhao Feng decisively chose to master the third-level earth magic, and the reason is not explained.

Tactical sub-skills:

Strong: Doubles the amplification effect of the battleline.

Formation: Command some soldiers to form a small battle formation (you can only copy the formation at the beginning of the battle), once every fifteen turns.

Change formation: After entering the battlefield, use one turn time to change the formation, which is only valid in the first round.

Different from the turn-based system of single-player hero invincible, the combat mode of the hero game is a combination of turn-based and real-time strategy, so the tactical skills have changed a lot, and the hero game has introduced the formation setting of the Three Kingdoms series in the tactical skills, and made certain modifications. First of all, heroes who choose the Law Class Specialization can't learn tactics.

Secondly, there are five types of formations that players can learn, and some special formations can be learned through special missions.

Arrow Array: Troops form an arrow state to charge, and the speed of the troops is increased by two for each level of tactical increase.

Cone Formation: The troops form a cone state to attack, and each level of tactics increases, the speed of the troops is increased by one, and the attack is increased by two.

Wild Goose Wing Formation: The troops are divided into two wings to surround the enemy, and the attack of the troops is increased by four for each level of tactical improvement.

Circular Formation: The troops form a circular state for defense, and the defense of the troops is increased by four for each level of tactical improvement.

Square Formation: The troops form a square state and are ready to stand by at any time, and each level of tactics is raised, the troops' attack is increased by two, and the defense is increased by two.

You can learn a formation for each level of tactics (you can't learn a battle formation without tactical skills). The specific kick-up for each formation is fixed.

The offensive and defensive attribute points increased by tactics are very practical in the early stage of the game, and when the game enters the middle and late stages, it is all about operations and soldier stunts, and the bonus effect of attributes is not obvious, and the attribute points increased by tactics are fixed, making tactics a little chicken. However, there is a formation that can be used for acceleration attributes, so it is still considered a powerful skill by players, and 60% of players in the game will learn tactical skills.

The three sub-skills of tactics are very useful, you can choose any one, Zhao Feng chose to change formations. Zhao Feng's expert-level tactics mastered four battle formations: arrow formation, cone formation, goose wing formation, and circular formation.

Offensive Sub-Skills:

Siege: A sub-hero and his subordinate units can be placed on the left and right sides of the enemy army to encircle the enemy.

Ambush: Hide some of the hero's soldiers (up to 10% of the maximum number of troops) as ambushes, and choose whether or not to let ambushes join the battlefield every 5 turns of the battle. Ambush skills can be detected by Scouting, but the number and type of ambushes cannot be detected by Scouting.

Reinforcements: Deploy an additional team of reinforcements (up to 10% of the maximum number of troops), when the battle situation is unfavorable, send reinforcements into the battlefield, and when the battle is over, regardless of victory or defeat, the reinforcements disappear.

The three sub-skills of the offensive technique are all very powerful and practical, and Zhao Feng chose to ambush soldiers.

Because the siege has high requirements for the player's operation level, Zhao Feng believes that if he uses his own operation level to fight against those top masters, if he uses the skill that requires technical content of siege, it will only increase the probability of failure.

Reinforcement skills, reinforcements are gone in a battle, reinforcements are useless when the level is low, and the reinforcements are reluctant to be reluctant, this kind of one-time use of high-level troops is a local tyrant's magic skill, not a player like himself to play.

So Zhao Feng chose the ambush, the ambush has an advantage, that is, to protect the senior soldiers, Zhao Feng can protect his most valuable troops with ambushes, every battle, after the fight, let the senior soldiers out to harvest experience, feel that they can't be beaten, don't let them out, so as not to lose the battle.

After the selection of the seven sub-skills, Zhao Feng's strength was qualitatively improved.
