When the light of the teleportation array disappeared, Ye Fei was already in a small camp outside the Death Grotto. The camp was surrounded by fog, and the electronic map could not show what the place was, it seemed to be a special space, and in the camp, only two old and toothless guards were guarding, a knight and a mystic.

The two old men looked at Ye Fei, and finally squeezed out a hint of a smile on their wrinkled faces: "Yo, there's a newcomer." The knight could barely stand on his feet with the hammer in his hand, and he even held it as if it were his own crutch.

The situation of the mystic mage was not much better, the body seemed to be hanging from the staff, and said lazily: "New here, what is your name, what city are you from, let me see if it is our countryman!" ”

"Most City, Hidden Bow at Night, I'm an Assassin!"

The knight's eyes lit up: "Oh, Moster City? Aha, I'm from the city of Turat, and our two cities are relatively close to each other, and we can be regarded as half of the same countrymen. ”

"Hey, old fellow, is this a fellow countryman? It doesn't count, it doesn't count The mage muttered softly over there, and pointed with his withered fingers to the stone piles not far from the camp, and said, "Back then, there were twelve guards here, including us, and now there are only two of us left; In the past 50 years, a total of 785 trialists have been welcomed here, and in the end, 452 have successfully left, 134 are buried here, and the rest have not even found their bodies.

Ye Fei was shocked: "What kind of place is this, so terrifying?" ”

"yes, it's scary." The knight laughed strangely and pointed to a dark cave not far away, "Go in, kid, kill all the monsters on the first layer, and you can come out for the second layer of trials." ”

The mage kindly reminded, "The monsters on the first layer will be constantly refreshed, and the refresh interval is five minutes. That is, if you can't kill all the monsters in five minutes, the battle will go on forever. ”

"Five minutes? What about the level and number of monsters? ”

"The level is the same as yours, the number, ninety-nine, all kinds of professions."

"I'll rub!" Ye Fei was dumbfounded, ninety-nine monsters, they have to be killed in five minutes, these guys think they are group attack mages, and they kill a large number of them.

The knight smiled: "You are an assassin, among the assassins who have been trained, only three have successfully passed the level, and the most recent one is the little girl from about eight years ago, who is also from Most City like you." ”

Another little girl assassin? Ye Fei's heart moved, and he blurted out, "Are you talking about Linda?" ”

"Linda? Well, it seems to be the name, it took her more than half an hour to pass the first layer of the trial. ”

Ye Fei took a deep breath, he didn't expect Linda to come to this place and pass the test. It seems that this is the kind of training camp that allows people to improve their strength, right?

Ye Fei didn't ask anything more, and walked directly into the Death Grotto.

In the grotto, there is an eerie and mysterious aura that keeps coming, and 99% virtuality makes it all so real. In the huge cavern, only the illuminated crystal on the top emits a dim light, which allows you to see the scene inside the cave. Here, all around is full of wandering undead soldiers, and you don't need to count them to know that there are ninety-nine of these undead in total, all of them are level 26.

"So many, how can it be killed in 5 minutes." Ye Fei secretly calculated his strength, and estimated that he could kill three blood-thin professions in ten seconds, which was 18 in one minute, and at most ninety in five minutes. This is still a situation where the blood of the undead is low, if it is a profession such as a defensive warrior, it is good to be able to kill one or two in ten seconds, but if you want to kill it in five minutes, how easy is it?

Unless...... Ye Fei suddenly thought of his Demon Breaking Dagger, if he used the Demon Breaking Dagger, would it be faster?

"Although the damage of the Demon Breaker Dagger is not high, but for ordinary undead monsters, the probability of triggering a must-kill is still relatively high, maybe it's really okay with good luck." Ye Fei thought about it, and replaced the weapon in his main hand with the Demon Breaking Dagger, so that his attack power had dropped a lot on the surface, but once the 'Fatal Blow' attached to the Demon Breaking Dagger was triggered, it would be enough to kill these level 26 undead monsters in an instant.

Ye Fei sneaked behind an undead soldier, his main hand stabbed three times, and the three consecutive attacks did not trigger the one-hundredth fatal attribute of the Demon Breaking Dagger, but the three undead soldiers pounced frantically: "Fresh flesh and blood, I smell flesh and blood again, is it a new human being?" ”

Just three level 26 monsters, Ye Fei didn't pay attention to it at all, he dodged their attacks sideways, his body was close to the undead monster who attacked before, and the dagger in his hand kept attacking, because he changed a dagger, the attack power of the main hand was almost negligible, and each attack could only cause more than 20 points of damage, so when the skill cooldown time except for the triple stab passed, he would use the skill attack with his off-hand. After all, killing monsters can't rely entirely on that fluctuating one-hundredth probability.

After about six or seven seconds, Ye Fei finally killed the first undead soldier.

"It's too slow!" Ye Fei frowned, this speed was much slower than he expected, but he saw that the undead soldier who had turned into a pile of white bones actually had a ghostly gray aura floating out and burrowing into the Demon Breaking Dagger.

What's going on?

Ye Fei was stunned for a moment, and while using the disappearance to get rid of the other two undead soldiers, he studied the dagger in his hand. This situation is similar to when the boss is killed, the Demon Breaker Dagger is upgraded, but now, the attributes of the dagger have not changed in any way, there is no upgrade, and the attack power is also enhanced, he is a little skeptical, is it just dazzled?

"Is it possible, killing a mob can also be upgraded, but the death breath provided by a mob is not enough?" Ye Fei frowned and was silent. He had always thought that this dagger was to kill the BOSS to upgrade, but now it doesn't seem to be the case, it seems that it is okay to kill the mob, otherwise the conditions are too harsh to kill the BOSS, and the copy BOSS can only be killed once. However, it's likely that this thing will be like another upgradeable item he equipped, the Carsons Bone Shattering Ring, and how many monsters you have to kill to level up like this.

As soon as he thought of this, Ye Fei suddenly became interested again, and his eyes moved towards another undead soldier beside him. Speculation can never get any conclusion, only practice and continuous experiments can prove whether one's speculation is correct. At the same time, he summoned Mia and asked him what was going on with the dagger in his hand.

"Demon Breaker Dagger?" Mia frowned and said, "The origin of this dagger is very special, but what is recorded in the library collections of various cities is very simple, it is just a very powerful dagger, but because it is too powerful, in order to prevent this dagger from falling into the hands of the wicked and causing riots, generations of sages have imposed countless layers of prohibitions on it. Gradually, he became such a dagger. Thirty years ago, during the Great War of the Decade, a hero of the city of Most used it against a vampire count, and has disappeared since, unexpectedly in the hands of its master. ”

Ye Fei listened patiently to Mia's words, and hurriedly said, "That's all?" I want to know, how did this dagger be upgraded, and how should the prohibitions you mentioned be broken? ”

"The way to upgrade the equipment is basically to kill monsters, some are to kill all monsters, some are to kill the undead, some are to kill beasts and so on. Your dagger should kill evil creatures such as undead, zombies, ghosts, and vampires, but I don't know if it is effective to kill all these types of monsters, at least it should be equal to or even higher than you or your dagger level to have an effect. ”

Ye Fei rolled his eyes, and asked the same as not asking.

Mia continued, "As for how those bans were broken, I'm sorry master, I can only consult the libraries of thirty-three cities. As she spoke, she winked at Ye Fei and said mysteriously, "Of course, if the master can let me enter the union libraries of various professional unions, especially the mystical mages, I think I will definitely gain something." The sages who attached seals to this demon-breaking dagger at the beginning were almost all powerful arcane mages, and only the arcane mages were proficient in all kinds of powerful prohibitions. ”

"Do you want to go into the Assassins' Guild's library?" Ye Fei snorted and said, Secret Mage? He doesn't have a way, the library of the professional trade union, even if you can enter, the reading permission you can get is extremely low, unless the permission of a union elder, vice president or the like, you can have a higher reading permission, but unfortunately, players don't care much about this kind of thing, so almost everyone goes to tinker with this kind of thing.

Mia grinned, clearly not very interested in the Assassins' Guild's library. She looked at Ye Fei killing monsters here, and suddenly exclaimed in shock: "Ah, this is the Grotto of Death, master, why did you come here, this is a good place to upgrade." ”

"Huh? A good place to upgrade? ”

Mia didn't say it, Ye Fei didn't care about it, but as soon as she said this, he subconsciously looked at his experience, an undead soldier he had just killed actually got more than 600 points of experience, more than twice as much as an ordinary level 26 monster.

"Double the experience." Mia winked at Ye Fei playfully, and her little wings twinked around him, "An extra hundred percent of the experience, plus the left eyeball of the Parges in your package and the three experience gems on the equipment, you can get a total of 113% additional experience points, which is very cost-effective." ”

What else can Ye Fei say? Double the experience, this is indeed a leveling mecca. He almost wanted to replace the Demon Breaker Dagger and kill it directly, but thinking about the secret of the Demon Breaker Dagger, he still held back, so he wanted to see if this dagger could be upgraded to kill monsters, right?

However, Ye Fei couldn't help but ask, "This is the first layer of the Death Grotto, is it the same situation for the following layers?" ”

Mia thought for a moment and said, "According to the classics, the Grotto of Death is a place shrouded in a mysterious force, there are seven floors, the first three floors, each layer has a huge number of monsters, the second layer is five hundred, and the third layer is a thousand. But from the beginning of the fourth layer, the number of monsters began to decrease dramatically, and what exactly is underneath, well, there is no record in the books. However, the monsters on each floor here are double experience, and the level of the monsters changes depending on your level. ”

Ye Fei was happy, with Mia, it was like carrying a mobile library, this elf could actually connect to the libraries of all thirty-three cities, which means that she was actually connected to some of the game's databases. No wonder it can answer all kinds of questions, it is indeed good.

But what's in the lower layers of the Grotto of Death? Ye Fei began to be curious, the trials of the second and third layers should be the same, and they need to be killed within a limited time, right? Thinking of this, Ye Fei not only was not afraid, but licked his lips excitedly, the more monsters, the more experience it proves, experience, this is a rare good thing!

He took out two undead soldiers and began to use food and potions that increased physical attributes for a short time, while various bombs were ready.

With a demon-breaking dagger in one hand and a bloody splinter in the other, he rushed into the monster pile like a whirlwind.
