Seeing that Hadley actually wanted to lift the entire iron box, Croge was shocked.

Although he had known that Hadley was a level 5 warrior through a few months, he himself knew how heavy this iron box was.

"Hadley, ...... inside this iron box," Croge immediately explained. He didn't want the other party to misunderstand, thinking that he wanted to make the other party ugly.

"It's okay, I'll try!" Hadley didn't think about it and waved his hand slightly. I don't try to lift this box anymore.

I saw a simple mortise lock on the iron box, and easily pulled it open.

"Bang!" With a bang, the iron box was opened.

"Good stuff, it's all good!" Hadley could see the materials inside at a glance, and he could easily distinguish several materials just from the color, all of which were refining materials worth a thousand gold.

Thundercloud Stone, Purple Sand Crystal, Thousand Illusion Magic Silver...... Hadley gently took out the materials one by one, the light ones were dozens of catties, and the heavy ones were about 500 catties. All the materials are neat and boxy, as if they had been cut. Where is the leftover material, it is clear that it has been refined and specially sold.

"Huh? What is it? Hadley picked up a purple wood box and was astonished. Because the wooden box is less than the size of a palm, it seems to be shaking from side to side when held in the hand, and it will be uncontrollable if you are not careful. I couldn't help asking.

"Haha, open it and take a look!" Seeing Hadley's surprised look, Croge laughed proudly. This is the most precious kind of gift he has prepared today. Even all the other materials combined are not as valuable as this gift.

"Oh, it looks like this must be a treasure!" Hadley was even happier. He had read a lot of books about refining tools and materials, but he couldn't guess what was in the box in his hand.

"Sizzle......" The moment he opened the box, Hadley gasped in shock.

Baby! Definitely a good baby!

"Deep Sea Blood Crystal Sand!"

Hadley couldn't help but exclaim.

Hadley, who knew the plot of the original book, felt that even if a supreme artifact appeared in front of him, he would not be moved. At most, when you have the main artifact, you will be very excited.

Because no matter how powerful the supreme artifact is, it can't be used by itself. The main artifact is different, this thing can be used very well by god-level powerhouses, especially the defense of the main artifact, which can be said to be unbreakable if it is not the main god.

And now, through countless books, Hadley knows a lot about refining materials. In addition to hemogarnet, black jadeite, and seryin, etc., they are from the heterotopic plane, which are very rare and precious.

The materials that belong to the original plane, among them are the deep-sea blood crystal sand, although it cannot be said to be rare, but it is not something that ordinary people can buy at will.

Deep Sea Blood Crystal Sand, unlike other materials, can be integrated into other materials. It can only be melted down and doped into weapons. It's like being nailed into the wood.

Yes, the Deep Sea Blood Crystal Sand is the weapon that is about to be 'nailed' into the weapon through a special refining technique when it is about to complete the alchemy.

There are only two functions of the Deep Sea Blood Crystal Sand.

One is to increase the weight of weapons. This is not important, because many precious materials have this effect. For example, black jade stone is more effective in this regard.

The second role is the most important.

Perhaps it has experienced some special environmental impact in the deep sea, and the deep-sea blood crystal sand seems to have two kinds of energy, just like magnetized ore, it has the ability to absorb on one side and repel on the other.

When Hadley first saw this introduction, he thought of magnets on the earth.

It's just that when the magnet is held in your hand, you won't have this feeling of swaying from side to side.

And the deep-sea blood crystal sand, if it wasn't for seeing it with his own eyes, just by the feeling of a box swaying from side to side, Hadley wouldn't dare to judge.

However, when you see it at first glance, you know it. Because of its special black, there is a faint blood red, and the color of blood red seems to be changing at any time. But when you look closely, it doesn't seem to change.

In addition to adding a small amount of weapons to the Deep Sea Blood Crystal Sand, it can make the weapon repulsive when attacking, that is, amplifying the attack. But there is a small drawback, that is, the consumption of fighting energy in the body is relatively large, which is not suitable for long-term battles.

However, there are some adventurers who are particularly fond of it. Because these adventurers often enter the Warcraft Mountain Range, whether they are fighting with humans or fighting with Warcraft, they all hope to be able to solve the battle in the shortest possible time. Because over time, the movement caused by the involvement of the battle will attract other people or Warcraft.

And the other function is some high-level defensive magic arrays.

As long as the Defense Magic Array is added to the Deep Sea Blood Crystal Sand, its defense power can be increased many times. Of course, the amount of magic crystals it consumes will also be an astronomical amount. However, for some big powers, magic crystals are like gold coins. As long as they can increase their defense, they will not hesitate to spend a large amount of magic crystals.

Because whether it is a human or a demonic beast, the fighting energy and magic power in its body are limited. But as long as there are enough magic crystals, the effect of the magic array is infinitely long.

Hadley didn't expect that he would easily get the Deep Sea Blood Crystal Sand like this.

When there is a small amount of this thing, it is generally not looked down upon by the big forces, because to use it to build a magic array, a large amount is needed. And ordinary warriors have no need for it.

The Deep Sea Blood Crystal Sand is completely of the kind that is hard to come by. In general, in small quantities, the recipient will use it himself to see the effect, or as a backup weapon, and will not use it in battle.

And when the volume is large, it will be sold to the big forces, so that in addition to befriending the other party, it can be sold at a sky-high price. The more blood crystal sand in the deep sea, the higher the value.

"Croge, I must solemnly say 'thank you'!" Hadley cleaned up his mood and said very seriously.

"Don't care. I heard that you have reached level 5 mage, so I guess it's a congratulatory gift! After all, those little guys also let you, as a teacher, bother a lot! Croge waved his hand, looking unconcerned.

Hearing Croge's words, Hadley immediately understood. The other party knew that after reaching level 5 magician, he deliberately wanted to befriend himself, and no longer relied solely on Yale's relationship to find his own help like before.

In the past, if I said that I still had some contact with them, but it was only for the sake of Yale's face, and the relationship with them was not very good. And now, the other party should be on good terms with themselves.

With several disciples of the family as nominal disciples, and the heavy gifts given today, it is equivalent to officially confirming this teacher-student relationship. And with the strength he has shown so far, he will not have any problems if he reaches at least level 7 magician. It's not too difficult to become a level 8 or 9 magician. While he was still weak, he gave a heavy gift in advance, and when he was strong in the future, he would make friends with a gift, but there was a world of difference.

"Well, by the way, I'm already a level 5 magician now, and I also have the right to recommend students, if the time comes, these little guys are willing to enter the Rand Magic Academy, they can just tell me directly!" Since the other party wants to befriend himself, then he will also give the other party a promise. After all, there is no love for no reason in the world, and more relationships rely on the connection of interests.

"With your words, I don't have to worry about their cultivation in the future anymore, haha......"
