The Frost Dragon's blood is only worth 35,000 contributions.

The sound dragon dragon crystal soared directly to the terrifying height of 500,000 contribution points?

Tang Lei was already a little speechless.

But if you think about it, the price is also normal.

After all, one is blood, and the other is a complete piece of dragon crystal.

The use of brute beast blood is still quite small, and it can't be drunk directly, so it can be said that there is no other use except for adding a little when refining medicine, or adding a little when refining weapons. Especially those unknown types of brute beast blood, they don't even dare to add it casually when refining medicine and refining weapons, so they are of little value.

The Nedan Crystallization is different.

Neidan crystals can also be used to refine medicines and refine weapons.

It can even be used directly as an energy crystal!

In the inner pill crystal, it may even contain the memories of the life of the wild beast, and even contain the natural power of the wild beast.

It can be said that the Inner Dan Crystal is definitely a huge treasure trove, and once opened, it is infinitely useful.

Not to mention anything else, the Golden Holy Dragon Dragon Crystal that Tang Lei got is also a demigod-level giant dragon dragon crystal, and the soul of the Dragon King Gaia contained in it directly allowed Tang Lei to get the "Dragon God Fighting Qi", allowing Tang Lei to become the first fighting genius standing at the top of the universe from a fallen and silent former genius and today's waste wood, and bloom again with gorgeous brilliance......

If someone tells Tang Lei now that your golden Divine Dragon Dragon Crystal is only worth 500,000 contribution points, Tang Lei will definitely reply: "You girl~ fart!"

Give Tang Lei 10 million contribution points, Tang Lei may not be changed!

From this point of view. Even if this piece of sound dragon dragon crystal is worth 500,000, it is not expensive at all, and it can even be said to be extremely cheap.

For Tang Lei. As long as you can condense the sound dragon species, it is worth spending one million or two million contribution points.

It's just that Tang Lei doesn't have that much contribution value now......

That's when I think it's expensive.

"Anyway, it's also a demigod-level Inner Dan crystal...... Tang Lei sighed lightly and put down this piece of sound dragon dragon crystal.

The Xuan Turtle Horn in his own chaos bag is also a demigod-level material, and if he bargains with the bone elder, he will add more than 100,000 contribution points. It is entirely possible to change to this piece of sound dragon dragon crystal.

However, materials like turtle horns are hard to find after all.

And the contribution value. As long as Tang Lei is still alive, he will definitely be able to earn it back!

Anyway, now that he can't condense the sound dragon dragon species for the time being, he is not in a hurry to redeem huàn, and finally Tang Lei decided. Put it in the Third Human Base Treasury first. When you have accumulated enough contribution points, it is completely too late to redeem huàn.

Now that you can exchange the Frost Dragon's blood, it's worth it.

Tang Lei put down the sound dragon dragon crystal, and walked around the special material room several times, and after confirming that there was nothing else he needed here, he was ready to leave.

Lin Xi and Long Wu also wandered around a few times, but they didn't find anything they liked.

Long Wu originally wanted to get a few magic weapons to improve his strength, but then he realized. Any magic weapon is not as good as your own claws, so just give up.

Pick up the Frost Dragon's Blood. Tang Lei, Lin Xi, and Long Wu left the special materials room.

"These two pieces?"

Putting the dragon's blood and the spar light brain in front of Gu Lao, Gu Lao glanced at it lightly.

"The spar light brain is a good thing with high practical value, this bottle of brute beast blood, is it also useful to you?" asked the bone elder casually.

"It was of great use. ”

Tang Lei replied with a straight face.

"A total of 65,000 contribution points, and you will be given a 9% discount, which is 58,500 contribution points. Gu Lao didn't ask much, and quickly calculated the contribution value that Tang Lei would consume.

"Bone senior, I don't know how much deposit I need to pay if I want to book a treasure in the treasure house?"

After buying the dragon's blood and the spar light brain, Tang Lei asked suddenly.

"Schedule: Deposit of 20% for one year and 40% for two years. The maximum booking is two years, after which the deposit is forfeited. Bone Elder said.

"I ordered a demigod-level Inner Dan crystal. Tang Lei did not hesitate to hand over 50,000 contribution points, and told Gu Lao the specific location of the sound dragon crystal.

"Is it the Inner Dan Crystal that can emit special sound waves? Do you want to use it to refine a Divine Soul Attack Weapon? Boy, let me remind you, Divine Soul Attack Magic Weapon is not so easy to refine. Bone Lao Zhengse reminded.

"The juniors understand. Tang Lei smiled indifferently and didn't explain much.

"Okay, this piece of Neidan crystal, I'll keep it for you for a year. ”

Gu Lao didn't ask any more questions.

After the completion of the huàn, Tang Lei still has more than 140,000 contribution points left.

It seems like a huge amount of money.

But you must know that Tang Lei has to collect 400,000 contribution points in one year, and now there is a shortage of 260,000 contribution points. From a certain point of view, Tang Lei is now the poorest person in the Third Human Base and the one who lacks the most contribution value.

But no matter what, this time he entered the treasure house of the third human base to exchange the treasures, and Tang Lei gained a lot.

After saying goodbye to Gu Lao, Tang Lei Linxi Longwu followed Yue Daoshan, left the treasure house of the third human base, and after walking through the long underground passage, several people returned to the sundries warehouse on the ground.

"During this time, you have devoted yourself to cultivation, and if you have any questions, you can contact me directly. If you want to go out to practice, try to be careful!" Yue Daoshan encouraged Tang Lei and Lin Xi a few words, waving his hand to let them leave.

Leaving the sundries warehouse, Lin Xi was extremely excited.

She rubbed her spatial wrist wheel, and she loved the brand-new mecha stored inside, and she couldn't wait to find a place to test the power of this new high-tech mecha.

"Girl, you taught me the secret method of the outer lion seal, and I also taught you a secret method. ”

Tang Lei said to Lin Xi.

The secret method of the outer lion seal was learned by Lin Xi alone, and Tang Lei would not.

Lin Xi handed over this secret method and exchanged it for 40,000 contribution points, Tang Lei can learn this secret method through the guò light brain system, but it needs to cost crystal coins or contribution points, so it is better to use one of his own secret methods to exchange with Lin Xi.

Under normal circumstances, the martial arts learned from the Third Human University cannot be taught to others.

But Lin Xi is the "original author" of the outer lion seal and has the right to teach it to others.

"Good!"

Lin Xi agreed directly.

Exchanging secret methods with Tang Lei, both of them can save a lot of contribution value, and Lin Xi will naturally not refuse this kind of thing.

Soon, Lin Xi taught Tang Lei the secret method of the outer lion seal, the secret method of the outer lion seal, which is the secret method of fighting words, leading the battle. Running this secret method, Tang Lei clearly felt that the battle intent in his body was rising, and it seemed that he could wield one hundred and two percent of his combat power. This secret method does not specifically increase the strength of the body, nor does it increase the strength of the fighting spirit, but in specific battles, it can wield extremely strong effects.

Tang Lei also taught Lin Xi a secret method of mudra.

But it is not the four that Tang Lei handed in, but one of the two secret methods of hole cards left by Tang Lei - the treasure bottle seal method with stealth effect.

This secret method cannot be learned at all in the light brain system of the Third Human University.

exchanging the treasure bottle seal for the outer lion seal is a big profit for Lin Xi!

"Okay, I'm going to retreat and meditate in the last few days, if it's okay, don't bother me!"

After the exchange, Tang Lei ignored the stunned Lin Xi and went back to the dormitory by himself. Now Tang Lei needs to immediately condense the Frost Dragon Dragon Species, and the others are all left behind. (To be continued......)
