In the past ten days in the Death Knight Castle, Lin Fei has killed less than a hundred Death Knights, and Lin Fei has already collected nearly 100 cards No. 007 'Servants of the Lich King-Death Knight' in his hand, so that the number of green cards collected at hand has reached 93.

In addition to the green cards, Lin Fei also played nearly twenty No. 022 gene cards 'Death Knight Sword Technique', and these twenty cards Lin Fei has all fused, which has greatly improved Lin Fei's understanding of swordsmanship, and his proficiency in the first style of 'Fallen Sword Technique' has also increased to 99%.

It can be said that at this moment, Lin Fei's 'Falling Feather Slash' power has reached an extremely terrifying level, and this move has surpassed all the attack skills that Lin Fei has mastered, becoming the most powerful move in Lin Fei's hands. A sword slashed out, directly triggering a black pillar more than three meters thick, and directly hitting the death knight was enough to kill the opponent in an instant.

And because of the improvement of sword proficiency, Lin Fei's combat power rating has increased to 870, and if the Black Feather Pupil and Demon Mark are activated, Lin Fei's combat power will break 1,000 for the first time, reaching 1000 points.

You must know that Lin Fei has only been on the Island of Evolution for a month, and the speed of increasing this combat power has increased several times compared to outside. It's just that it's obviously not easy to leave the Island of Evolution, and so far none of the contractors have completed the task of collecting cards, so no matter how high the combat power of the contractors on the Island of Evolution is, it won't help. In fact, according to Lin Fei's understanding, many of the contractors who entered this island of evolution did not want to go out again.

On this island of evolution, there is no need to go through all kinds of terrible missions, and you can even live in the town all the time as long as you want. Of course, the premise is that you have the ability to earn the time you need to survive.

From the perspective of ordinary people, there is almost no difference between surviving here and surviving outside, and it is safer here, so I simply don't go out. However, Lin Fei will not choose to mention this path, Lin Fei still has a lot of concerns in the real world. He must leave the Island of Evolution.

However, it seems that it is quite difficult to get a set of cards and leave Evolution Island now. Although Lin Fei now has 93 kinds of green cards in his hand, the further he goes, the more difficult the process of collecting cards will be. Lin Fei could almost conclude that the kind of Fallen Angel with a combat power of more than 2,400 points that he and the Iron Woman had seen in the Hell Zone was the source of a card, that is, in order to get together a set of cards, it had to be defeated.

2400 HP. If he wanted to kill the opponent, Lin Fei felt that his ontological combat power would have to exceed at least 2,000 before there was a glimmer of hope. And by now, Lin Fei's combat power has almost reached its peak, but with various states, it is only 1,000 points.

Twice as bad.

This chasm alone is difficult to cross, besides. Lin Fei couldn't conclude that the Fallen Angel in the Hell Area was one of the hardest sources of cards to obtain, what if, what if it was even harder?

Lin Fei knew that maybe he would have to stay on this island of evolution longer, two months, three months, or even more, but Lin Fei believed that one day he would reach that level and get all the cards together and leave here.

This time. In the corridor, in the distance, the footsteps of the Death Knight were heard, heavy and regular. And Lin Fei immediately judged from the footsteps that these were two Death Knight patrols.

So, Lin Fei slowly picked up a rune short sword with a unique shape from the side. The hilt of the broken sword is detached from the blade, but it is connected externally, like a delicate metal rod with a slightly curved knife tied to the tip. This kind of curved blade can be stabbed or slashed, and from the appearance, this rune broken sword is also quite good-looking.

As for the original iron-blooded razor, it had been scrapped in Lin Fei's almost tyrannical use, but Lin Fei found that a weapon of average quality could not perform a falling feather slash at all, just like a white quality long knife that looked good, Lin Fei had just performed half of the slash, and the knife shattered directly. And even if it is a high-quality weapon, it will be greatly worn out after casting the Falling Feather Slash, because of the experience of the iron-blooded razor, Lin Fei of the Xuanbing Sword will not dare to use it indiscriminately. If it weren't for the No. 031 white card 'Rune Short Sword' that he played later, Lin Fei would have no weapons to use at all. …,

This No. 031 white card Lin Fei played a lot, which was enough for Lin Fei to perform a slash. At the moment, he is holding a rune short sword. Lin Fei slowly entered the stealth state.

At this time, the hidden effect of stealth on some powerful enemies is becoming less and less obvious, but for Lin Fei, the effect of this concealment is better than nothing, even if it can delay the opponent to find himself by one more second, it can also give Lin Fei a relatively big advantage.

Especially when facing two Death Knights.

Slowly, the two Death Knight patrols walked to the passage where Lin Fei was, and Lin Fei, who was hiding in the shadows, made a decisive attack.

Now Lin Fei's starting hand has become a lightning storm, and the current lightning storm covers an area of ten meters, which can cause extremely strong damage to the target, but if the opponent has mastered some special abilities or has extremely high combat power and is extremely strong, then the lightning storm often cannot kill the target, but it can still cause minor injuries or paralysis.

The Death Knight is clearly a powerful opponent with special abilities. At the moment when they were attacked by Lin Fei's lightning storm, bone shield phantoms appeared on their bodies to resist the attack of the lightning storm. Obviously, it's just that the lightning storm can't help these death knights at all, but fortunately, Lin Fei didn't plan to kill the enemy in one move.

Lin Fei also knew that the floating bone shield defense ability on the death knight was called the 'death bone shield', which was also a kind of gene card, but this card was more than ' The Death Knight Sword Skill is even more difficult to come out, Lin Fei killed so many Death Knight and only played one, and Lin Fei found that the defensive effect brought by only one fusion was very average after fusion, so he didn't bother to use it, because the bone shield he cast could not withstand the blow of the Death Knight at all, and even some low-level undead monsters in this castle, such as a skeleton soldier called Death Bone, could shatter their bone shield defense at once. According to Lin Fei's thoughts, he had to fuse ten of these 'Death Bone Shield' cards with this ability, and then he would only achieve the defensive effect of the Death Knight after using his ability.

This also made Lin Fei understand one thing, these abilities need to be constantly fused with the same ability cards to improve the effect.

Circling behind a death knight, Lin Fei raised the rune short sword and slashed down, and with a brush, a huge black light shone, as if a waterfall had fallen for nine days, and this waterfall was still as black as ink.

Boom!

With a loud bang, the attacked Death Knight was directly shattered, and this result was obviously in Lin Fei's calculations. If you attack directly, even if you are at 99% proficiency, you may not be able to kill the death knight with the defense of the death bone shield in seconds, so the lightning storm at the beginning is used to consume the power of the opponent's bone shield. And in the end, if you make up for it, no matter how fierce the death knight is, he can only become a real 'death' knight.

Lin Fei spun on tiptoe, and then swept a sword, and the black light that Luo Yu burst out this time at another angle, bursting out on the waist of another death knight. The bone shield, which was originally consumed by the lightning storm, shattered in an instant under the black mang's slash, like a piece of shattered glass.

Without the Death Bone Shield, the Death Knight's armor was cut through in front of Lin Fei like a piece of cardboard, and in the next second, the Death Knight was directly cut into two pieces, killing him instantly.

Lin Fei stepped forward to pick up the cards dropped by the two death knights, and when he saw a red 'Death Bone Shield' card dropped, Lin Fei smiled, and then quickly left the scene. Lin Fei knew that other death knights would arrive soon, so he had to leave as soon as possible at this time.

After arriving at the safe area, Lin Fei fused this card, and then found a few dead bone monsters with a combat power of only about 300 to 400 to test his bone shield defense effect, and found that the death bones could shatter the bone shield with two or three attacks, although it was still not practical, but at least it was much better than at the beginning. ..., "Keep improving your combat power!" Lin Fei said secretly, and then his body disappeared into the darkness.

Another fifteen days passed.

Lin Fei finally fused enough ten bone shield cards, and the death bone shield was finally able to resist the death knight's three attacks before it was broken, as for those dead bones, Lin Fei stood still, and they didn't want to break through the defense of the death bone shield.

In this way, Lin Fei's defense methods have increased to two, one is the black feather defense, and the other is the bone shield defense.

However, the proficiency of the Falling Feather Slash is still stuck at 99%, and it has not been able to reach 100% for a long time, and as for the second style of the Fallen Sword Technique, 'Earth Splitting Slash', it is still impossible to learn.

The Fusion Death Knight Sword Skill Card was obviously invalid, and Lin Fei, who had been wandering the Death Knight Castle in the dark for a whole month, was also tired of the darkness and coldness here, and planned to leave here.

During this time, the iron-blooded woman did not contact Lin Fei, and Lin Fei naturally did not contact her. As for the extent to which her combat power has improved, Lin Fei doesn't know. And when Lin Fei sneaked and was about to leave the Death Knight Castle, he heard the sound of a battle in the distance.

Lin Fei frowned, who made such a loud noise here? It's all about looking for death.

Curious, Lin Fei followed the sound and sneaked over, but saw that in a large hall, several contractors were fighting with two death knights.

Some of these contractors are in the form of giants, and some are half-human and half-beast, and their combat power is above 700, which is quite good. They quickly relied on their coordination and numerical superiority to kill one of the Death Knights, but one by one they surrounded the second one with an excited face.
