Chapter 131 Dangerous Dark Corrosion

  The siege of dark creatures lasted for a long, long time.

   This length is calculated in days.

  Yes, the dark creatures attacked the Heihe Fortress for five days and five nights!

  Zhang Feng finally took advantage of the daytime to see clearly what the so-called dark creatures were.

  But after he actually witnessed it with his own eyes, there was some worry in his expression.

  Dark creatures are not just one or a few species.

   But many, many different kinds.

   Beasts in the mountains, dwarves in the ground, and giants in the mountains are fairly common in this world.

  But demons, harpies, and some black elves are not the races that this world should have.

   There are even dead bodies of beasts and people, and skeletons and zombies are also common.

   What's even more frightening is that many creatures have been fused and become strange monsters.

  The kind where one can feel that one's sanity is about to drop just by looking at it.

  According to the NPCs in this world, the dark creatures were originally normal creatures. Although they were hostile to humans, they could still communicate.

  But after the darkness invaded, eroded these creatures, and even opened the passage to another world, the world has fallen into war.

   "Beware of the erosion of darkness."

   That NPC said so, and Zhang Feng saw him turned into an ugly walking corpse the next day, and his head was chopped off by another mercenary.

   At this time, Zhang Feng discovered that the dark creatures in the early stage were actually here to die.

  They died under the city, and the darkness in their bodies began to diffuse.

   Those whose life level is below level 20 will be affected by the "Dark Corrosion" effect. If this effect cannot be removed within a certain period of time, they will completely become slaves of darkness.

   Like those dark creatures who were sent to death, they attacked Heihe Fortress.

  So after the battle, whether it is an official soldier or a mercenary like a player, they need to be rotated.

  Go to the rear to accept the test and remove the effect of the dark erosion.

  The effect of dark erosion is so powerful just by being close, not to mention the damage caused by dark creatures.

  The health level has not reached level 30, and the effect of dark erosion will be even more amazing if it is damaged by dark creatures.

   Need to withdraw from the battle immediately, under the care of other soldiers, quickly return to the rear for treatment.

   Only when the health level reaches level 31 or above, can they completely ignore the attacks of dark creatures and fight normally.

  But on this battlefield, apart from Zhang Feng, who has an SSS-level talent, who can deliberately increase the life level to such a high level.

  Even An Yunfeng needs to go back from time to time to take a rest to avoid being too deeply eroded by the darkness.

   The rotation on the battlefield is every 3 hours, and about four groups of people go back and forth.

  But except for the group of Zhang Feng who can go back more, the reduction of staff in other batches is very serious.

  The five-day and five-night battle of the dark creatures consumed at least one-fifth of the Black River Fortress's military reserves.

  And as time goes by, the speed of death and injury is getting faster and faster.

  Zhang Feng and the others changed from going to the city twice a day to three times.

   Even because too many people died, the original four batches became three batches.

  The time has also been extended a lot.

  The consumption of materials has reached a point where it cannot make ends meet.

  Although the food is still sufficient, the treatment supplies have reached the warning line.

  The supervising team killed many people who wanted to escape in the next two days.

   It is conceivable that the defense of Heihe Fortress has begun to feel shaky.

   "These dark creatures are just making a test, which makes Heihe Fortress feel unsupportable."

  Zhang Feng looked a little helpless, "It seems that the main task this time is indeed a bit too difficult."

   "After all, the Heihe Fortress is just a small fortress, without any defense system, and it is only newly built."

  An Yunfeng has received a lot of news these days, and he is still very confident about it. "The real fortress in the Death Mountain is only the Afterglow Fortress, and the defense system there has reached the point where it can be called inhuman."

   "The Black River Fortress and the Bluestone Fortress behind it, in the final analysis, are just to delay the steps of the dark creatures and make the Afterglow Fortress ready."

   "It is said that this time, the higher authorities only need to defend Heihe Fortress for ten days, which can be counted as completing the task."

  An Yunfeng's words did not make Zhang Feng feel better.

   "Just listen to what the NPC says."

   "It is said that the Black River Fortress is just a small fortress to delay time, but you need to see how difficult the dark creatures are."

   "This ability to corrode is too unfriendly to human beings. Only a very small number of people can be immune to the effect of dark corrosion."

   "If the Black River Fortress can't stop it, can the Yuhui Fortress behind it?"

   "They also need to face the bad situation of dark erosion."

  Zhang Feng's words did not stop An Yunfeng, she shook her head and said, "You forgot one thing, the level of this world is not low."

   "Isn't the role of the Black River Fortress and the Bluestone Fortress just to test the attack methods and abilities of the dark creatures, so that the Afterglow Fortress can understand it, and then carry out targeted cracking?"

   "Perhaps when we retreat to Fortress Sunset, the effect of dark erosion will disappear?"

  Zhang Feng shrugged his shoulders, the invasion of dark creatures in this world is not just the present.

   Long before their arrival, the world had been invaded by darkness.

  If the effect of dark erosion could be resolved, the Heihe Fortress would have already done so.

  But An Yunfeng's words can't be wrong.

  After all, Heihe Fortress can already pull out the effect of dark erosion here, so give the rear a certain amount of time to study the nature of this dark erosion.

  Perhaps Sunset Fortress can crack this kind of thing in a targeted manner.

  Zhang Feng sat on the top of the wall, looking at the dark creatures staring at this place in the distance, his heart suddenly became dark.

   These guys must have a commander, otherwise it would be impossible to attack the city like crazy in the early stage, and now they have tightened up a large number of dark creatures and stayed in the distance.

   And the strength of this commander must not be underestimated.

   It is very likely that it is a lord-level boss with extremely high combat intelligence and experience, far exceeding the normal human level.

  After all, even the 200-level leader-level boss could be sent over as cannon fodder and killed before, so the commander cannot be too weak.

   "Equivalent to a four-turn lord-level boss, and still without any flaws, a lord-level BOSS whose strength is at its peak."

  Zhang Feng scratched his scalp, feeling itchy at the root.

   This is just a way to test in the early stage. The real behind-the-scenes boss of the dark creature, I am afraid that the lord-level boss here is not close to it.

   This time the main mission is probably really dangerous.
