According to the book, the reason why World of Warcraft is powerful is the source of its energy. The magic crystal is like the battle crystal of human warriors. It contains extremely huge energy. The more advanced the magic crystal, the more energy it contains.

The greater the energy.

But the only difference is that humans cannot absorb the fighting spirit contained in the magic crystal at all, because the fighting spirit in the magic crystal is extremely violent and mixed.

However, magic crystals also have a wide range of uses, and the most obvious use is formation!

For example, the Twelve Elephants of Death, although this huge formation was jointly deployed by a Tyrant Realm and a dozen Emperor God Realm experts, they were already dead. As thousands of years passed,

However, the formation can still display powerful energy and effects, and its fundamental energy source is magic crystal.

You don't need to think about it to know that there must be many powerful magic crystals buried in the many corners around this formation.

In addition to the magic crystals, there must be many special spirit gathering arrays buried that can gather the spiritual energy of heaven and earth, just like a machine, converting the spiritual energy of heaven and earth into special energy to supply the needs of the array.

Secondly, magic crystals can also be used for medicinal purposes.

For example, the Explosive Flame Pill that Qin Fei took before was said to contain high-grade Tianfeng Magic Crystal.

Magic crystals are also divided into attributes. For example, the magic crystal in his hand is a wind attribute magic crystal.

It's a pity that the giant eagle's strength is only average, and the energy contained in this magic crystal is not much. At most, it is only a second-order magic crystal.

But after all, this is the trophy of my hard-fought battle, and I have to keep it as a souvenir.

It is said that this thing is quite valuable in the market. After all, in today's big world, Warcraft has long been extinct, and things are rare and valuable...

"Buzzing..."

"Huh?" Just when Qin Fei was about to put the magic crystal into his arms, Xue Yin Ba Dao, who had a spiritual connection but had never had any reaction, actually sensed a special emotion and seemed to be very anxious...

Qin Fei frowned, as if he sensed what Xueyin Ba Dao wanted, and quickly spread out the magic crystal in his hand.

Qin Fei has known about this for a long time. Even when he was tempering his body with Sky Fire, it was fortunate that the Snow Drinking Saber absorbed the remaining terrifying energy in the Sky Fire liquid for him. Otherwise, he would have burned his body and died.

Forgot...

However, because he had not yet advanced to the soul level and reached the Heavenly Soul Realm, he was unable to communicate with the spiritual consciousness in Hegemony. However, at this time, he actually sensed a trace of the emotion of the sword spirit.

Qin Fei seemed to feel something and quickly put the magic crystal in his hand on the blade. Suddenly, a strange scene appeared. The extremely hard magic crystal melted quickly and turned into a colorful and very dense substance.

It contains very pure energy.

Just when Qin Fei was pleasantly surprised, thinking that he could absorb this pure energy, he saw that this thick energy quickly disappeared at a speed that could be seen with the naked eye.

All of them were absorbed by Xueyin Ba Dao?

Qin Fei held the Xueyin Ba Dao tightly with both hands, sensed it for a long time, and waited for a long time, but did not receive any energy feedback from the Xueyin Ba Dao...

Holy shit, where’s the energy?

Qin Fei's eyes almost fell to the ground.

Is this gone?

Have you absorbed it all? At least leave some behind...

"Huh?" At this moment, the Xueyin Ba Saber trembled slightly, and Qin Fei was surprised to find that a trace of black liquid seeped out from the blade, and soon gathered into a very small drop at the tip of the blade.

It dropped gently to the ground, and then quickly solidified, turning into a small black ball.

Qin Fei was surprised and quickly squatted down to pick it up, only to find that this small black unknown object was as light as nothing, just like a black foam.

As for the energy contained in it? It’s all gone?

Qin Fei put it to his nose and smelled it, but there was no smell at all!

Then, he suddenly thought of something, and his expression suddenly changed.

You are scolding, this is not the absorbed energy, this is waste, garbage, shit, right?

The more Qin Fei thought about it, the more he felt it was possible. When he thought about what he had just put this thing on the tip of his nose to sniff, his expression suddenly turned cold!

He turned around blankly and looked at the Xueyin Ba Dao in his hand. He still looked dazed and hadn't changed at all!

Qin Fei was completely speechless. A good magic crystal turned into a piece of mouse excrement, and the Xueyin Ba Dao that absorbed the energy of the magic crystal did not show any special effects at all!

Qin Fei cursed in his heart for a while, but had no choice but to give up. After all, Xueyin Ba Dao had suffered a lot with him, and had put in a lot of effort. Just eat it.

Qin Fei thought very simply. The Snow Drinking Sword was a magical weapon. The reason why it didn't show any special effects after absorbing the energy of the magic crystal was probably because it didn't have enough energy.

After all, this is just the magic crystal of a giant eagle.

Qin Fei found a bluestone and sat down slowly. He was like a frightened bird now. He was injured and he did not dare to move at will.

"Huh?" But just when he was sitting on the bluestone and looking around, he suddenly discovered something strange and his eyes suddenly lit up!

Behind him is a cliff covered by woods, with vines climbing all over the cliff.

However, the dense vines before had been burnt to ashes, revealing the nature of the cliff. What surprised Qin Fei was that there was a deep cave in the middle of the high cliff.

This cave was previously covered by vines and could not be seen at all.

Qin Fei suddenly stood up, staring at the cave, and in his mind he remembered the whispers of the people around him when he entered the ancient tomb.

In this ancient tomb, anything is possible. Even if you don't get a treasure like the Ten Thousand Years Ice Lotus, as long as you are lucky enough to have an adventure, your strength will most likely improve by leaps and bounds!

Adventure coming?

Qin Fei looked around like a thief, and after making sure that there were no dangers such as monsters around, he looked at the cave on the cliff with burning eyes.

However, he was smart enough not to rush. He sat cross-legged on the bluestone and rested for an entire hour. After his body recovered to 80% to 90% strength, he slowly stood up and stared straight at the cave.

There are crises everywhere. Although Qin Fei is a little frightened, thinking about the reincarnation of these twelve fatal elephants, he also knows that he does not have too much time.

When this illusion reincarnates, it is absolutely impossible for him to come back to get it.

Although it is still early for the twelve-hour reincarnation, who can know what dangers there will be in this cave and how long it will delay him?

He bent down and grabbed the heavy blood seal, and muttered: "Damn it, if you eat my magic crystal, you will be in danger soon, so you have to work hard!"

With this muttering in his mouth, Qin Fei rushed up with a few strides. At the same time, he looked around with vigilant eyes. He jumped suddenly, stepped on a protruding bluestone on the cliff, used his strength to leap forward again, and stood firmly at the end of the cave.

On a bluestone outside.

At this time, he had a clear escape route in his mind. If there were any dangerous monsters in the cave, he could quickly return to the original route in a short time.

It's very quiet in the cave, so quiet that it's a bit scary

The dark cave is very deep and winding, and precisely because of the winding nature of the cave, if you don't go in, you won't be able to see the scenery inside.

And this cave obviously didn't have only one entrance, because standing at the entrance of the cave, he could clearly feel the breeze coming out of the cave, with a bit of a permeating 'whispering' sound.

The silence around him, the darkness in front of him, and the strange noises coming from the cave gave Qin Fei a layer of goosebumps all over his body, giving him a creepy feeling.

He waited quietly for nearly an hour again. After struggling hard in his heart, he decided to go in and take a look.

There is a moonstone in his Nai Ring, but the objects in the Nai Ring cannot be taken out. Now he can only explore slowly by himself. Fortunately, his eyes have been specially tempered. Although the cave is pitch black, he can still see.

The wall of the cave was already covered with moss, but Qin Fei with a sharp eye could see at a glance that there were human traces on the wall. This made him cautious again.

You must know that those who can leave traces here may be masters of the Emperor God Realm thousands of years ago.

According to the book, the great world of ten thousand years ago was rich in aura, with powerful men who knew destiny flying all over the sky, and innate masters running all over the place. Although the technology was not developed at that time, it was completely a world of warriors! If someone jumped out at random, it was not you.

This small three-star heaven can compete with it.

Taking two steps forward, Qin Fei suddenly remembered something. He gently bent down to pick up a stone and hit it hard on the stone wall. With the blessing of his fighting spirit, the stone hit the wall and quickly hit it again.

It bounced to the ground until it flew towards the curved hole, and a faint echo sounded...

Qin Fei's ears twitched, and he keenly discovered that this cave was just as he thought, very deep!

"Kaka--" At this moment, Qin Fei suddenly heard a strange sound, but it was extremely familiar!

"There is a mechanism!"

Qin Fei quickly changed and retreated quickly. At the same time, fighting energy surged out of his body. Once he got a sharp arrow, he could jump out of the cave in an instant.

But what surprised him was that the friction sound of the mechanism was a bit violent. After a few gentle sounds, it seemed to be stuck by something and stopped moving.

"What's going on?" Qin Fei looked strange.

After the cave became silent again, Qin Fei's expression changed, and he suddenly thought of a possibility, that is, the mechanism here has long been ineffective due to thousands of years of experience and no one to protect it.

Although he thought this in his heart, Qin Fei was still a little scared.

Half a moment later, he muttered: "Wealth and wealth are found in danger, only love for Bill will win!"
