When Li Feng was about to rush into the big crack, the fireworks flying letter wrist wheel on his wrist suddenly burst out of a fireworks, and someone sent him a flying letter.

Before leaving, Li Feng left a wrist chakra on the Black Wood Cliff to prevent accidents, and when he suddenly received a flying letter, he couldn't help but sink his heart slightly. The copycat wrist wheel burned by Li Feng has not had time to be put into use at this time, otherwise Fang Cai would not have had to wait for someone to come to him.

Looking at the contents of the note, Li Feng breathed a sigh of relief.

The letter was sent by Ferdinand, the Grand Governor, and it only said that the Elven Sky Knight had discovered that there were an army of about 50,000 and were heading towards Blackwood Cliff. According to the speed of the army's advance, it will take at least two days to reach Blackwood Cliff, so there is no need to worry about safety for the time being.

In half a day, everyone can rush back, and there will be no delay.

As for the origin of this army, Li Feng knew very well that ninety percent of them were Parthian visitors he met two days ago. Just when I went back, I wiped out this army by the way, and presumably the three masters of Atlantis who came from afar would be happy to help.

Marching in the mountains, the other party will definitely not be able to carry many heavy weapons, and the Elven Sky Knight has already come up with a positive reconnaissance result, so Li Feng is not too worried.

Putting away the note, Li Feng led everyone into the big crack.

As soon as he penetrated the black fog, an astonishing heat wave hit his face, Li Feng was suffocated in his breath, looking at the boundless sea of fire in front of him, shocked and speechless.

The power of the forbidden spell was really shocking, although Li Feng didn't see the spectacular scene when the forbidden spell was first released, but just looking at the boundless fire in front of him was enough to shock.

The terrain where everyone was located was very high, and the field of vision was wide, and this fire burned out at least dozens of miles away, far beyond the limit that everyone's line of sight could reach, and the forbidden spell magic really deserved to have the power to destroy the world and destroy the world.

Li Feng learned from the mouths of the people left in the Great Rift that the Spark Forbidden Spell of Amos was just a small drop of fire falling in the army of skeletons at first, and then all the skeletons were ignited, and in an instant, they spread to places beyond the reach of the eye, forming the current magnificent sea of fire.

Spark Magic is a strange magic that manifests its power by visualizing the number of enemies. This magic was created specifically to deal with necromancers. A little spark falls among the skeletons, as long as there are undead skeleton warriors nearby, the spark will continue to spread, and at the highest time, it can even spread a hundred miles away, this magic is the most practical magic for fire magicians to destroy the skeleton army.

Li Feng suddenly remembered something and shouted, "Wait, you just killed so many Immortal Beasts, you won't forget to take out the Demon Crystal, right?" ”

"Haha, of course the magic crystal must have been taken out, so many super-level underworld beasts, as well as lord-level and even king-level underworld beasts, if you don't take out the magic crystal, wouldn't it be a tyrannical thing?" Efilas laughed, then shook his head again, and sighed: "But time is a little short, many of the corpses of the underworld beasts have not had time to snatch them out, and now they have been burned by forbidden spells, how many alchemy materials have been wasted." ”

Super-rank demonic beasts are beings that stand at the top of the food chain pyramid, and even if they die, every part of their body can still play a huge role. In the hands of an alchemist, he can refine a very high-quality magic prop, not like Li Feng, who just burned a magic array diagram and finished it, which is the roughest alchemy technique.

For example, the bloody phoenix killed by Li Feng can be refined into a shield that combines both beasts and demons. The Cursed Arrow of the Dark Bone can also be extracted from other bones, which is not only extremely sharp, but also adds Sacrifice and Bloodthirsty double aura damage once it hits the opponent, but the effect of the aura is much reduced.

The blood of the bloody phoenix can also refine the bloody battle stimulant, and after taking it, it can temporarily greatly increase the strength of a person in the case of serious injury, and the maximum limit can be doubled. Of course, compared to the talent of the Bloody Phoenix itself, the effect of the Bloody Fight Doping must be a few streets behind, and there are quite a few sequelae.

The feathers of the Bloody Phoenix can also be made into a Cloak of Blood Feathers, which can be worn on the body, allowing ordinary humans to go berserk like berserkers or orc warriors, greatly increasing their combat effectiveness.

The heart of the Bloody Phoenix can be refined into a Blood Badge, and the mage holding the Blood Badge can summon a high-level Immortal Beast to help in battle, and can also bless all magic with a double aura of sacrifice and bloodthirstiness.

A king-level bloody phoenix can contribute so many alchemy materials, and everyone has killed a total of five king-level underworld beasts, so how many top-grade alchemy materials should be?

Moreover, other lord-level underworld beasts, super-level underworld beasts, quasi-super-level underworld beasts, and high-level underworld beasts, even if the materials contributed are a little inferior, but that is relatively speaking, even if it is the corpse of a high-level underworld beast, for ordinary magicians, it is a rare alchemy material, not to mention that there is such a huge number.

As long as he thought of this, Li Feng felt that his flesh hurt terribly.

"Fortunately, Alan, your subordinates have enough space rings, and most of the corpses of super-level underworld beasts have been snatched out, otherwise I will die of distress for you." Efilas added another sentence, which suddenly made Li Feng's mood brighten.

Immediately, Eferas shook the space ring on his finger and poured out the corpses of the five king-rank beasts, which made Li Feng laugh so much that he couldn't close his mouth.

Although everyone was forced to kill and live, if there was no such loot to make up for the frightened little liver, Li Feng was afraid that he would be able to lead people to the underworld again.

The highest value in the body of the underworld beast is the magic crystal, these five king-level underworld beasts have not been touched by anyone, Li Feng stepped forward, rolled up his sleeves, raised his hand, and very skillfully took out four magic crystals in extremely perfect condition.

"Dean, this is your trophy," Li Feng threw back to Efilas one of the underworld beasts that did not dig up the magic crystal, this underworld beast was killed by the dean, and among the five underworld beasts, Li Feng alone contributed four.

"Mentor, you don't seem to have a magic crystal in your hand that can store mana, do you?" Li Feng casually threw a huge magic crystal to Amos, and said with a smile: "This magic crystal is filial to you." ”

Generally speaking, super-level magic crystals can store mana, but they require magic crystals of the same lineage. But after reaching the great level of the king rank, the magic power of different lineages can also be stored, although the effect is much worse than that of the same lineage, but a king-level magic crystal can at least double the combat power of the great mage.

Amos smiled and calmly took the magic crystal, in fact, he also has props in his hand that can store demons, but since it is the filial piety of the disciple, there is no need to be too polite, otherwise it will look angry.

Li Feng thought for a while, and then gave the corpses of three of the underworld beasts to Amos, and the remaining one underworld beast to Epheras, and said: "Mentor, dean, you don't have to shirk it, anyway, there are no talents who can do alchemy in Heimu Cliff, these superb alchemy materials are in my hands, and they are completely collectibles, so it is better for you to take them to study alchemy." ”

The corpse of the king-level underworld beast, even if it is regarded as a collectible, it must be the best collection, Li Feng is so generous, it is obviously a bit unexpected by the two great demon masters.

Amos didn't accept it happily this time, muttered for a while, and said, "I will have time in the future, come to Blackwood Cliff to live for a while, and help you refine these materials into magic props, which can be regarded as killing two birds with one stone." ”

Amos likes to study those rare things, and the corpses of the underworld, especially those of the king-rank underworld, must be good subjects to study. However, Amos didn't want to take advantage of his disciples, and he didn't need any magic props, so it was the best choice to make these materials into props and give them to his disciples.

Efilas hesitated a little, he didn't covet that alchemy material, but if the Demon Martial Arts Academy could have a few more superb magic props as the treasure of the town, it would be very exciting for him, the dean.

Li Feng was overjoyed, thanked his mentor first, and then saw Efilas' hesitant expression, and couldn't help laughing: "Dean, you don't see the outside like this, do you?" I'm going to cooperate with the academy in the future, and these alchemy materials will be considered bribes for you, hehe......"

The opportunity to win over the Great Demon Master, others can't find it if they want to, and ordinary people can't have such a big deal as Li Feng, and the corpse of the King-level Demon Beast is not something that anyone can take out.

Eferas finally accepted it, anyway, it was not the first time he owed Li Feng a favor, at most he would find a chance to repay it later, thinking that with his ability as a great mage, this debt could still be repaid.

The crowd stayed underground for more than an hour before leaving, and for so long they didn't see any other powerful necromancers come back to the field.

It is said that there is an undead archmage who has escaped, and the underground dark world is the lair of the necromancer, they should have gotten the news a long time ago, and they should not have been so slow to react.

It was Amos who solved Li Feng's doubts, although the area of the underground dark world was not as large as the entire Titan Continent, it was no problem to be comparable to any super human empire, and even exceeded. With the necromancer's footsteps, it may be difficult to get over in a short period of time.

In fact, just jumping out of twenty necromancers at one time was already terrifying enough, and these twenty necromancers must have been stationed near the Great Rift to arrive so quickly.

When they left, the fire was not extinguished. According to Dean Epheiras, this fire can burn for at least three days and three nights. So at least for three days, it would be impossible for the necromancer to get out of the Great Rift.

Coming out of the big rift, Li Feng sent a flying letter to Ferdinand, confirming the location of the Parthian army, and preparing to destroy this army on the way back to the road.

Several masters are really willing to help destroy each other's heavy equipment, and now the two countries are in a state of war, even if they are two great mages with weak national concepts, when they are facing the Parthian Empire, they are willing to weaken the opponent's strength, and they are not afraid that they will touch the mage's covenant - anyway, no one sees the barren mountains and mountains, right?

Even the Red Devil Sword Master, an outsider, is willing to help strike at the Parthian Empire within the scope of his ability. Having lived in Poseidonia for more than ten years, the Red Devil Sword Master has a sense of belonging to the Atlantean Empire.

"By the way, Alan, have you figured out who is the one who sent you flying?" Gerald endured it for a long time, but finally he couldn't resist his curiosity.

Several masters also pricked up their ears, and after Li Feng returned to the Great Rift, he had been fiddling with a large number of magic crystals. As for the person who just made a move on Li Feng, several masters have not yet gotten a definite answer from Li Feng's mouth.
