Expert Learning Ability: Players gain an additional 40% of experience. Its sub-skills are:

Combat Experience Mastery: After each battle, all units will no longer have equal distribution of experience, and the experience stones obtained in this battle can be assigned to certain units, but some experience will be lost in the distribution process (experience will be reduced by 10%).

Quest Experience Mastery: For any quest completed by a player of this faction, the number of experience stones will be randomly increased by 1-3 (non-stackable).

Garrison XP Mastery: In the city where the hero is stationed (must be the lord of the city), the maximum amount of soldiers who can upgrade through the garrison is increased by one level.

Zhao Feng's Hunter also has the ability to learn, and the sub-skill he chooses is Mission Experience Mastery, but the effect of Mission Experience Mastery cannot be stacked, so Velina's sub-skill is Combat Experience Mastery.

With combat experience mastery, Velina can freely allocate experience to some soldiers when farming wild monsters, which can make the efficiency of farming monster training more flexible, the average level of wild monsters in difficult maps is level nine, and a small map actually farms about 1000 wild monsters a day, which means that Zhao Feng can get a level 11 senior soldier every day.

But the wild monster hero who leads the team is also level 9 (63 soldiers), that is, a small map will brush out fifteen or six wild monster troops in a day, and it is impossible for any hero to take a tenth-level soldier to farm wild monsters, and an eleven-level purple sub-hero with a full tenth-level soldier can barely guarantee that the monster is not damaged, that is, although theoretically you can get a high-level soldier a day, it actually takes seventy-seven days to train a batch of (77) high-level soldiers.

However, after Verina mastered the sub-skill of combat experience mastery, no matter how many soldiers she leads, she can concentrate her experience to train one or several of them, ensuring that she can obtain one high-level soldier every day, and the way to obtain high-level soldiers is more flexible.

Moreover, Velina's expert-level learning ability, experience gains an additional 40%, although it will be deducted by combat experience mastery by 10%, but there is also a 26% experience bonus (140% × 0.9), which means that you can actually get 1.26 high-level soldiers per day.

Of course, it is also thanks to Zhao Feng's mastery of the magic of the gate of time and space, if there is no gate of time and space, it will take a day for a hero to cross a small map, and it will often take four or five days to go through a small map. Not to mention running all over the map to chase wild monsters. With the Gate of Time and Space, not to mention the monsters that farm one minimap a day, even five or six monsters on the minimap can be brushed.

After calculating, Zhao Feng began to command Velina to do the exclusive map mission, and as before, Verina was promoted to twelve levels, and at the same time obtained a fifth-level Internal Affairs Hall, a fifth-level barracks, and a third-level magic tower blueprint.

With Verina farming in the second layer of the underground world, Zhao Feng began to prepare to attack the first layer of the underground world.

In fact, before occupying the second layer of the underground world, after Zhao Feng transported the thousands of eighth-level cannon fodder in the old nest, Zhao Feng had already sent troops to the first layer of the underground world.

Zhao Feng took the Sea of Skulls as the main force, led the troops to start attacking the players in each dungeon, and every time he conquered a city, he sent three teams of heroes to lead the troops to garrison, one team of four blue heroes, and the remaining two teams were one basket and three greens.

The four heroes of each team, the main hero is level 10 and level 11, with a level 9 high-level vampire mage, a secondary hero with an eighth-level soldier, one with a vampire, one with a skeleton archer, and one with zombies, ghosts and other miscellaneous soldiers.

By the third day of the new map, the underworld had entered fifty or sixty players, and more than thirty cities had been established.

Although the players who have entered the difficult level map now also have the level of eleventh, their strength is not too high for the time being, and half of them are players who have just been upgraded to level eleven.

So what Zhao Feng had to do was to expel them before their strength grew.

As a powerful level 12 player, Zhao Feng has a very big advantage when dealing with level 11 players.

The players in the first layer of the underground world are almost all dungeon players, and each player can basically have about ten level 11 high-level soldiers.

However, in the first two batches of hard maps, each medium map had a level 12 High Lord.

Because according to the game setting, the player's troops on the low-difficulty map can be transported to the high-difficulty map without restrictions, but the player's troops on the high-difficulty map are generally not allowed to bring back the low-difficulty map (see section 9 for details), this is to prevent the player from hoarding troops on the high-difficulty map and returning to the low-level map to abuse the small number to grab territory.

Therefore, the average level 11 player will not bring all of his powerful troops into the new map at the beginning, for fear that they will not even be able to hold the territory of the old map after being destroyed. They will all go into the new map to explore the water, and they will feel that the new map is relatively safe, and they will feel at ease to develop in the new map.

Therefore, Zhao Feng wanted to show strong strength before they developed, scare away some people, and speed up his own development.

In fact, it is true that when the players of the first layer of the underground world developed the existence of Zhao Feng, a level 12 player, they were a little drummed in their hearts, especially after discovering that Zhao Feng had built three cities, they were even more worried.

So fifty or sixty players have only built more than thirty cities, and most of them are second-level villages, and they want to see how it goes.

So when Zhao Feng started the strategy, most of the players retreated and prepared to go to other maps to develop, for such players, Zhao Feng was not too much, allowing them to withdraw with their main forces. After all, Zhao Feng had cooperated with them in his previous life.

Only a few players still wanted to compete with Zhao Feng, but with the support of Zhao Feng's strong forces, they dragged on for a few days, and finally couldn't resist and retreated.

During this period, there were also players entering the underground world through the portal, Zhao Feng directly transferred the four purple heroes he had just obtained, and each group of three sub-heroes, blocking the two portals in the underground world.

On the tenth day of entering the new map, Zhao Feng occupied the underground world, and on the twelfth day, Zhao Feng completed the exclusive task of the map, and this time, it was Roth who was promoted to the twelfth level.

Being able to monopolize two difficult-level minimaps in twelve days made Zhao Feng proud. What made Zhao Feng even more excited was that almost every medium-sized map had a temple, and the temple on this medium-sized map was the core building of the first layer of the underground world, so Zhao Feng had a second temple.

Zhao Feng, who has two hard-level mini-maps, can get two and a half eleven-level soldiers every day just by farming wild monsters, and 10 high-level soldiers can be obtained in a month of game time (four days in reality), Zhao Feng decided to sacrifice five eleventh-level soldiers every month in exchange for one twelve-level soldier.
