Under normal circumstances, for a siege battle, especially a siege battle above the fourth level town, if half of the strength of the siege party is not killed during the siege and defense battle of the city wall, then the siege battle will be lost.

Because the offensive and defensive battle of the city wall is the most difficult to fight, the defender has an arrow tower, a city wall, and the help of a magic tower, such an advantage cannot kill half of the opponent's combat effectiveness, and the street battle and the city hall offensive and defensive battle behind it basically have no chance of winning.

And Zhao Feng's combat power was only lost by a quarter during the attack and defense of the city wall.

So there is no suspense in the last two battles.

In the state that both sides do not break the defense, they can only cause a mandatory attack, especially after the defender has no city walls and moats, Zhao Feng can summon skeleton soldiers as soon as possible.

With the help of skeleton soldiers, this war of attrition that forced a drop of blood was finally ended with Zhao Feng's victory.

This is the second sixth-level city owned by Zhao Feng - the Castle of Flowing Clouds.

At the same time, this sixth-level city is also a city with a very complete architecture, not only a sixth-level barracks, but also a fourth-level magic tower. The only pity is that I don't know what the previous special building was, after being captured by Zhao Feng, the special building was transformed into a unique building of the cemetery clan: a soul tower, a dark canopy, and a skeleton transformation field.

Zhao Feng's heart is dripping blood, three high-level special buildings, transformed into the most ordinary special buildings of the cemetery clan, the system is really impossible for players to take advantage.

Enter the Department of the Interior and look at the tasks of the Interior Office, but there is a good task.

Pursuit: A-Rank Camp Mission, after the Castle of the Flowing Cloud has been conquered, the remnants of the swamp clan who were originally entrenched in the Castle of the Flowing Cloud have scattered and fled, go and get their heads, pay attention, they are Rogue, if you don't exterminate them as soon as possible, they may attack your mine or territory. Quest reward, 20 experience points. 0/2000。

After Zhao Feng saw this task, he understood that the Flowing Cloud Fort was a sixth-level city, and the number of reserve soldiers was 2000.

Zhao Feng was complaining in his heart, the siege battle was fought three times, all of them were the same heroic legion, where did the troops of this legion come from, didn't they use reserves?

Although this task is very unreasonable, it is good for Zhao Feng, not to mention 20 points of mission experience, that is, those 2,000 remnants, if they are all eleventh level, it is enough for Zhao Feng to upgrade 20 eleventh level soldiers to twelfth level. If it's level twelve, that's 20 level thirteen soldiers.

The entire map of the city and mine is already in Zhao Feng's hands, basically, as long as these rogues enter the vicinity of the city or mine, Zhao Feng will know immediately, and then use the gate of time and space to fly over to solve it.

I took the task at the Interior Office, and then went into the Magic Tower to have a look.

I thought that the system would not leave new magic for players, but this time I left a reward for Zhao Feng.

System Prompt: The magic research of the fourth-level magic tower has been completed, whether to check.

Note: This magic research is hosted by the swamp clan, the swamp clan is a low-magic race, unable to study the fourth-level magic, if you look at it directly, you will get a new magic randomly, the magic level is three-level two-star, two-level three-star, first-level four-star. Players can also directly burn an existing magic into the magic tower, and then use this magic research to upgrade the magic star, so that players can directly learn the magic of that star.

Normally, when the player conquers a city, the city's magic tower will be cleared to zero, regardless of how far the city's magic tower has been studied. This is to prevent players, especially guild players, from farming mana through sieges.

However, the system cities of the crazy level map are extremely difficult to conquer, so additional rewards will be given to players who succeed in the siege.

For example, the task that Zhao Feng just received was an additional reward, but that was the basic benefit in the extra reward, and every fifth-level system city would have this task after it was conquered.

And the reward of the Magic Tower is an additional reward for the sixth-level city.

Of course, this reward should be more logical and not too costly for the player.

Taking the reward of the Magic Tower as an example, in order not to let the player make too much money, if Zhao Feng chooses to check it directly, the result is that Zhao Feng will get an existing magic, such as a second-level three-star lightning arrow or a first-level four-star magic magic arrow or something.

At most, if Zhao Feng's character explodes, it may be a first- or second-level new magic, and Zhao Feng will definitely not be able to get a third-level and two-star new magic.

Therefore, choosing to upgrade the existing magic level is the highest reward.

If the city conquered by Zhao Feng is a stronghold, a high-demon race outside the swamp, then this additional reward will not fall on the magic tower, even if the probability is small, the system is afraid that the player's character will explode and directly get a fourth-level magic.

If it's a high magic race, the biggest bonus for this bonus is likely to be a special building that is more practical.

Zhao Feng didn't have the luxury of new high-level magic, and it would be good to be able to use this opportunity to give an existing magic star ascension.

Zhao Feng chose the Gathering Spirit Thaumaturgy.

Zhao Feng burned the Gathering Spirit Thaumaturgy into the Magic Tower, and then clicked Research.

System Prompt: Congratulations to the player Skull Sea, the results of the magic tower have been studied for a long time, and the new magic level 3 two-star spirit gathering thaumaturgy has been obtained, please set the star ascension effect of the two-star spirit gathering thaumaturgy......

The reason why Zhao Feng chose the Gathering Spirit Thaumaturgy was considered.

For heroes, it doesn't make sense whether one-star or two-star thaumaturgy, any magic, as long as the hero uses it 100 times, it can be upgraded from one star to two stars, 1,000 times to three stars, and 10,000 times to four stars......

But it's not the same for the French class.

Vampire mages can learn magic from levels 1 to 5 at levels seven, nine, eleven, thirteen, and fifteen.

At level 8, you can learn level 1 two-star magic, at level 10 you can learn level 1 three-star magic or level 2 two-star magic, and at level 12 you can learn level 1 four-star, level 2 three-star, and level 3 two-star magic.

However, the prerequisite for a French class to learn high-level magic is that there is magic of that level in the Magic Tower.

Zhao Feng's main force used to be mainly level eleven, but with the development of the game, especially now, Zhao Feng's main activity area has been transferred to the Crazy Map.

The computer of the crazy map, the troop level is as high as thirteen or fourteen, and the eleventh level of troops is slowly not used.

Therefore, Zhao Feng needs to improve the level of his main force, and it is estimated that he will use at least the twelfth-level troops to fight the world in the future.

The vampire mage's housekeeping magic is naturally Soul Gathering thaumaturgy, and a level 12 vampire mage can already learn three-star and second-level Spirit Gathering thaumaturgy.

However, Zhao Feng's magic tower has not yet researched the third-level two-star magic. After all, the magic of ascending stars is also a ruthless test of character. Judging from the fact that Zhao Feng has a lot of first-level four-star magic in his hands now, Zhao Feng's character is very poor.

Therefore, with such an optional opportunity to improve the magic star, Zhao Feng naturally wanted to use the Gathering Spirit Thaumaturgy.

In fact, there is a reason why players have few high-level magic in their hands at this stage.

There are three ways to get new magic: Eagle Eye, Quests, and Magic Towers.

The new magic obtained by the Eagle Eye Technique cannot be upgraded to a star level, cannot learn from each other, and also occupies the hero's magic position, this defect was told to Zhao Feng by the Sea Dragon King before.

The task is obtained, and there is a systematic probability that the card is there, and it is destined that only a very few lucky people can get it.

The main way is to research new magic in magic towers.

However, Level 3 Magic Towers require Level 5 Town and Level 3 Magic Tower Blueprints, which are not available to the average player.

And the fourth-level magic tower needs a sixth-level city and a fourth-level magic tower, except for the thirteenth-level great lord, only the grand guild and a few twelfth-level great lords have a sixth-level city.

The average player is lucky to get the architectural drawings of the sixth-level city, and they don't dare to use it, once they use it, the next day he will find that a group of wolves from the big guild will appear around his territory.

Having a level 4 magic tower does not mean that there is level 4 magic.

If there is no twelfth-level law hero sitting in the magic tower to conduct research, he will never be able to study fourth-level magic, because the expert-level wisdom technique that can only be mastered by twelfth-level heroes is the basic prerequisite for learning fourth-level magic.

Heroes of the ninth to eleventh levels can only study the third-level two-star magic in the fourth-level magic tower, and they can only study the third-level two-star magic.

It's not a twelfth-level hero, and he can't even learn fourth-level magic, can he still study it?

However, the beginning of magic research is a year (the real time is 52 days), and it cannot be interrupted, and there is a probability of studying fourth-level magic, which is much lower than the probability of first, second, and third-level magic.

Now which big lord has a surplus of twelve-level heroes to squat in the magic tower, and even if there is, it is to send a twelve-level hero to study once in a while, who dares to throw a twelve-level hero in the magic tower all the time.
