The depths of the cave are pitch black, but through the eyes of the crow, Lin Fei can still see gold and various treasures everywhere, and the black dragon has a hobby of collecting these items, so each dragon's den is like a huge treasure trove.

Spider-Woman's Black Widow Spider quickly skimmed over the mountain of treasure and continued to crawl inside, and after a few moments saw a black mass entrenched there, which would have been mistaken for a huge rock if you didn't look closely.

And Lin Fei could see at a glance that this thing was the black dragon.

Even if it is entrenched like a small mountain, and the dragon armor that is as black as ink and hard as iron, there is no doubt that this is the black dragon.

Although it was through the detection of the crow's eyes, Lin Fei could still feel the strength of this black dragon, but Lin Fei himself was not what it used to be, although the black dragon was strong, it was not a completely unshakable existence.

The black widow spiders were already very close to the black dragon, and at this distance, they began to weave spider webs to enclose the black dragon. The eight Black Widow spiders were extremely fast, and in a few moments they hung up webs like curtains, which were as thick as steel wires, and so tough that nothing could break them.

According to Lin Fei's plan, that is, to use the spider web to trap the black dragon first, and then start killing, if there is any accident, the spider silk can also do the role of blocking the enemy.

"I'm going in, you guys stay outside, summon all the flying mounts, if I let you go you have to leave right away, you know?" Lin Fei spread his wings and said to Li Chunan and the others behind him.

Li Chunan naturally knew Lin Fei's character, it was useless to say anything at this time, and she also knew that Lin Fei's strength was not bad, even if he really couldn't defeat the black dragon, at least there should be no problem in escaping, so she nodded and agreed.

Spider Woman and Cheetah, of course, are the same.

"Good!" Lin Fei then spread his wings and flew in.

Halfway through, Lin Fei landed and then entered the sneak and slowly moved forward with a breath-holding breath, the spider web barrier in front of him left Lin Fei a one-person-high passage, which was convenient for Lin Fei to enter and exit. And the Black Widow Spider didn't quit all this last night, but stayed around to make a plan for Lin Fei.

Entering a sufficient distance, Lin Fei also saw the huge black dragon, and the air of the entire cave would circulate faster with every breath the other party breathed. In addition, the smell of the dragon's lair is extremely fishy, but Lin Fei has been to a disgusting place, and this place is just a pediatric.

Throughout the time, Lin Fei could check the black dragon's combat power rating, but this glance made Lin Fei frown, this black dragon's combat power was as high as 1800.

Evolution Island has very little information about the Black Dragon, and nothing is known about its size, combat power, abilities, and special abilities, as well as its strengths and weaknesses. Because those who dared to challenge the black dragon died without exception.

In Lin Fei's opinion, the combat power of 1800 does have this qualification.

Lin Fei was still thinking, but at this time, the sleeping black dragon suddenly opened its eyes, it seemed to sense something, and a pair of huge dragon eyes instantly turned, staring at Lin Fei's location.

"Not good!"

Lin Fei suddenly felt like he was being targeted by a terrifying beast, and goosebumps rose all over his body. But he didn't think about it, and with a point, he released the lightning storm first.

After three months of training, Lin Fei's various abilities have reached saturation, such as the lightning storm, Lin Fei can cover a full 50-meter range after being released, and the power is more than twice as strong as before.

It can be said that even against the Death Knight, a large-scale lightning storm is enough to kill some. But at this moment, something happened that made Lin Fei stunned, under the terrifying lightning storm, the black dragon climbed up quite easily, and seemed to not care about the huge lightning that hit his body. …,

"Some games and legends have mentioned that the black dragon is immune to all magic attacks, so the rumors are true, and the lightning storm is also a magic attack, so it doesn't work against the black dragon at all!"

Lin Fei looked at the black and hard black dragon armor on the black dragon's body, and said secretly in his heart.

Although it was immune to magic, the black dragon obviously didn't like someone to break into its lair to provoke it, so it let out a roar, but it pounced on Lin Fei violently.

Lin Fei did not retreat, but advanced, and took out a rune short sword in his hand and fought directly with the black dragon.

As soon as he came into contact with Lin Fei, he knew that the black dragon was powerful, and he was too far behind the other party in terms of strength alone, in addition, the black dragon's dragon armor was abnormally strong, and the rune short sword could not even leave white marks on it, and there was already a gap.

Just as Lin Fei was about to perform the Fallen Sword Technique, the black dragon suddenly saw the black feather wings behind Lin Fei, and a trace of doubt flashed in his eyes.

This change in his eyes was keenly captured by Lin Fei, and he stopped launching the Fallen Sword Technique almost instantly, and afterwards Lin Fei felt very lucky for his own inspiration, if he hadn't stopped the attack temporarily, maybe he wouldn't have discovered that secret in this life.

The moment Lin Fei stopped attacking, the black dragon also stopped attacking very strangely, it landed on all fours, staring at Lin Fei with a pair of eyes. And Lin Fei didn't seem to expect the other party to suddenly stop attacking, but he was also standing there, staring at this black dragon.

One man and one beast are actually frozen here.

If this scene is revealed, no one will believe that the black dragon is a tyrannical creature, and will hardly show mercy to any creature, let alone live in peace with anything. But now, it is not choosing to attack again, and while that situation does not last long, at least for now, this delicate balance is maintained.

Lin Fei's mind was also spinning, and the idea that he had just stopped attacking was just a flash of inspiration, but it was because he saw a little doubt and incomprehension in the black dragon's eyes. So Lin Fei paused, and to his surprise, the black dragon seemed to have the same pause, so Lin Fei simply stopped attacking, and as a result, the black dragon also stopped.

Lin Fei didn't know what was going on, but there must be something strange in it.

It's just that next, Lin Fei didn't know what to do, the black dragon didn't attack at this time, and it was not easy for him to step forward and make a move, and subconsciously Lin Fei thought that he must have triggered something, otherwise the black dragon would not be able to stop.

At this time, the black dragon on the other side actually spoke.

In the information collected by Lin Fei, the black dragon has always been violent when he sees the invader, it will kill all the creatures that enter its lair, it likes to collect treasures, it has the strongest **, but none of it is about whether the black dragon can speak. So as soon as it spoke, Lin Fei was stunned.

"Fallen Angels...... What do you mean by that? Are you going to break the old covenant? This is what the black dragon said, and after this sentence passed through Lin Fei's head, it was interpreted into some useful information.

First of all, the black dragon can speak out, indicating that their intelligence is not low, in addition, the black dragon knows the fallen angel, otherwise it is impossible to see his black wings and show that kind of eyes, and the second is that the most important thing is that there is a covenant between the fallen angel and the black dragon, which means that the two sides are allies.

Lin Fei's mind was spinning, but he knew that he might have caught a very critical thing, and the most important thing at the moment was to stabilize the other party to obtain more information, so he took the opportunity to say: "No, I will not break the covenant!" ”

This is the only thing that Lin Fei can say at the moment, as for what the content of this covenant is, Lin Fei doesn't know at all. …,

"So what are you doing here? Could it be that the Titans are coming? The black dragon roared suddenly, and it spread its wings and began to look around.

Titans?

Lin Fei's heart moved, and a thought suddenly popped into his mind. Many creatures have natural predators, which can also be called rivals. As between fallen angels and angels, they cannot coexist and will always be enemies. And the old enemy of the black dragon is said to be the Titans, as for why there is such a fate between them, it is no longer known, the two sides will definitely fight to the death when they meet, that's for sure.

Just now, the words of this black dragon revealed a very crucial information, that is, the so-called covenant must be related to the old enemy. It is very likely that the fallen angels have signed a covenant with the black dragon to deal with the Titans together, of course, the fallen angels will not help the black dragon for no reason, and another content of the covenant must be that the black dragon will also help the fallen angels against the forces of heaven.

Only when this understanding is it called normal and can it make sense. Then everything before is easy to understand, the black dragon thought it was a titan invasion after seeing a fallen angel break into its lair, so he reacted before.

Lin Fei knew that he had inadvertently discovered a very important plot, and maybe he could take advantage of this. After all, the races included in this covenant happen to include three cards that they haven't obtained yet, and this is definitely more than a coincidence. Lin Fei thought of the limit of the highest combat power on the Island of Evolution, if he was rated according to the combat power of 1500, how could he get the last few cards? Maybe this covenant is the key to collecting the last few cards.

Moved by his heart, Lin Fei thought of an idea, at least to stabilize this black dragon first.

"The Titans didn't come, but they've been brewing a conspiracy lately......" Lin Fei began to ramble nonsense.

Outside the dragon's lair, Li Chunan was anxiously waiting for Lin Fei's news, but it had been so long, and there was no movement at all inside, which was a little too abnormal.

There were a few times when she was already planning to rush in, but she hesitated again when she thought of Lin Fei's previous request. And the spider girl on the side also told her that the information transmitted back by the eight black widow spiders who had just entered was also very normal, although she didn't know the specific situation in the dragon's lair, but at least it wouldn't be very bad.

A few minutes later, just when Li Chunan couldn't wait any longer and was about to break in, the figures of Lin Fei and the eight black widow spiders appeared at the entrance.
