Du Feng didn't know that there were others who were worried about his cultivation, so after taking the task, he left the city through the side gate. The task of hunting the leader of the fire fox is actually quite difficult. One is because the level of the Firefox leader itself is high, and the other is that the number is relatively rare. And the ability to hide is very strong, and it is not easy to find.

But all this was not a problem for Du Feng, he had the experience of hunting the leader of the fire fox once. With the cultivation of the Void Sea Realm, I took on this seventh-level task, in addition to being able to exchange for the Yin Yuan Stone, the contribution value of those fire fox cubs that I killed with my hands will be calculated, which is really a double win.

The task of finding the Firefox Cave was naturally handed over to Xiao Hei. Its nose twitched a few times, and it soon found a cave. There was a big battle in the cave, killing the leader of the fire fox and a litter of ordinary fire foxes. Du Feng left in style, leaving the guards of Lei City there to count for a long time.

Wait until he understands the inventory and records the contribution value. On Du Feng's side, he had already killed another litter of fire foxes, and he didn't forget to take the tail of the fire fox leader. This thing is what the city defense department really wants. After destroying the five Firefox Caves, Du Feng stopped. Leaving the Thunder City guards there to count slowly, he returned to the city first.

The demon beasts in the volcanic group, although the more you kill, the better, may always kill the same kind. Demon beasts of the same race can't kill too many at once. This will upset the balance of the monster beasts and cause more serious consequences. Take Firefox as an example, their combat effectiveness is not high among the demon beasts of the grade. The main targets are fire rats and fire earthworms. Retaining a certain amount of fire fox can inhibit the reproduction of fire rats and fire earthworms.

Don't look at the small size of the fire rat and the fire earthworm, but the destructive power of the city wall is huge. All the firefoxes in the volcano group combined, may not be able to break through the defenses of Thunder City. However, if the fire rats and fire earthworms are allowed to develop unscrupulously, they may destroy Thunder City and even several surrounding cities.

Fire earthworms, in particular, are capable of devouring soil and even gnawing at foundations. If the number reaches a certain level, the city's defense line will be destroyed. The fire rat, on the other hand, will eat a large number of plant roots, resulting in a decrease in the production of medicinal herbs, spiritual fruits, and other things necessary for martial artists.

Ecological balance is a very strange thing, often those divine beasts at the top disappear, and it does not have much impact on the balance of the entire ecosystem. On the contrary, the disappearance of the creatures at the bottom of the middle will bring extinction to mankind and even the whole world.

Du Feng still had this kind of knowledge, so he didn't blindly kill in order to earn Yin Yuan Stone. With the tail of the five fire fox leaders, he happily returned to Thunder City.

"You're here so soon?"

Du Feng had only been out for a day in total, and then he returned to the city defense office to hand in the task. The little girl who was in charge of receiving him before felt a little incredible. I thought that it would take several days just to find the Firefox Cave. It is even more difficult to lure the leader of the Firefox out. Basically, more than half of the foxes in the entire cave will be slaughtered before the leader will show up.

This person named Du Feng went out for a day and came back to hand in the task. Is he going to hand in the task, or does he want to cancel the mission? If you cancel the mission, you will have to pay a fine. This rule is also quite ruthless, if you can't kill the leader of the fire fox. Not only do the ordinary Firefoxes you kill not give you the calculated contribution value, but you also have to pay an additional fine to cancel the existing task. Because if you don't cancel an existing task, you can't take on the next one.

"Take a look. ”

Du Feng threw over a Qiankun bag and asked the staff to check it for themselves. This time it was relatively low-key, and no one in Lei City's martial artists stared at him, so it didn't attract onlookers.

Tail, the tail of the leader of the firefox. The staff probed their divine sense into the Qiankun bag to check, and immediately saw a big tail as bright red as a flame. That's right, this is the main item of the mission, and it is only with this item that the mission is completed.

Wait, there is more than one. She first saw a firefox leader's tail, and then she saw a large number of firefox nedan. Then I saw a big bright red tail, also from the leader of the firefox.

No, could it be that there are two fire fox leaders living in a cave. According to common sense, there is a competitive relationship between the leader and the leader, and they do not live in the same cave. So how did he get the tails of the two firefox leaders, he couldn't find two firefox caves in one day.

It's already considered luck to find one, and it's a joke to find two Firefox Caves in one day. Just when the staff thought it was incredible, she saw a third bright red tail, which naturally came from the leader of the firefox. Coupled with the countless Firefox Neidan, she had already figured it out.

This Du Feng is either superior in strength, or he has already saved the tails of many Fire Fox leaders, and deliberately came to Thunder City to exchange for Yin Yuan Stone. Generally speaking, there are only ghost cultivators and demon cultivators who need a large number of Yin Yuan Stones. Seeing that he looks white and tender, it would be a pity if he was a demon cultivator.

Ghost cultivation is unlikely, because ghost cultivation is, to put it bluntly, a cultivation choice for human warriors after death. A good living person, no one will choose to be a ghost cultivator.

Then the staff found the fourth and fifth, and when the number reached this point, she became numb. Not as shocked as when I first saw the tail of the second firefox leader, maybe someone brought the stock. If you want to prove everything, you have to wait for the guard who is responsible for counting the contribution value to return.

According to his observations and statistics, it was immediately possible to know whether Du Feng was superior in strength or premeditated. While the staff was anxiously waiting, the Lei City guard who was in charge of tracking Du Feng hurried over.

The corpses of the fire fox in five holes were counted, and they almost didn't exhaust him to death. The rules of the City Lord's Mansion are so perverted, and the contribution value of killing demon beasts and materials such as Neidan must be counted separately. Kill a thousand Firefoxes, and bring back a thousand Neidan without ghostwriting. Similarly, bringing back a thousand Neidans does not mean that this time it is a thousand firefoxes that have been killed. Therefore, the contribution value of the killing must be calculated according to the corpse of the demon beast.

"How much!"

The little girl looked at the Thunder City Guardian with expectant eyes, eager to know a result. Such a personable son, if it was a ghost cultivator, it would be a pity. But if he relied on his own skills to clear five Firefox Caves and Caves in one day, then his strength would be too strong. is such a handsome and chic, and powerful son, how can he not make people tempted.
