From Aige's mouth, Qin Miao learned about the calculation method and exchange rules of this underworld currency......

According to the level of the undead, the corresponding crystal nucleus will contain elemental energy multiplied by the level of ten, with the exception of boss-level crystal nuclei, (for example, the crystal nucleus of a level 50 skeleton warrior only has 500 energy value; However, the level 50 mini-boss has more than 5,000 energy values, the fifth-order big boss or elite big boss each has tens of thousands of energy values, and the energy values of the lich and the dark knight are more terrifying, both of which are more than 500,000).

These energies can be directly used by sub-god-level powerhouses, on the one hand, to maintain the operation of the camp, and on the other hand, they can also be directly used in battle. As a result, the crystal nucleus, as the most practical item in the underworld, naturally replaced the status of useless gold coins.

"Then, how are these energy values exchanged?" Qin Qiao pointed to Youngor who was immersed in refining medicine in the tent and asked Egger.

"Depends on what grade of potion you need."

Iger replied:

"For a general large-scale healing potion, 10 energy points can be exchanged for a bottle; Large mana potions, 50 energy for one bottle. ”

Qin Wan nodded noncommittally, this price is not too expensive, but he should not buy these things in a short period of time, and there are still a large number of them stored in the Ring of Glory.

"A powerful antidote of five products, 500 energy is worth a bottle."

"Four-grade attribute magic potion, 600 energy value for a bottle ......"

Hear here. Qin Miao couldn't help but furrow his brows. Damn. I knew that I could directly use the crystal nucleus to exchange the finished magic potion from the underworld. He wouldn't have used all the crystal nuclei except the lich to sponsor the dinosaur mage to toss his sealing skills.

"It's hard to find materials for three-grade attribute potions. There are 500,000 energy points of finished products to exchange for a bottle...... If not. You can accept the task. Go and find the most important material yourself. Then pay 100,000 energy values worth the Earth Crystal Nucleus and let Youngor help you refine ......"

500,000 energy points?

Qin Weak sweated like rain. Xindao, why don't you just tell me to go and kill the lich?

He only had three Lich Land Crystal Nuclei left in his hand. This sixth-order big boss earth crystal nucleus. Inlaid dark gold equipment will have a high chance of producing high-quality attribute lands. Potions are wasted in order to be expendive. It's too extravagant.

It's better to farm the undead!

The task of a thousand pieces is a bit daunting, though. But it shouldn't be difficult, after all, he has a little baby in his hand, the king of shopping, the speed of picking up things and grabbing things is first-class, and the number of undead in this underworld is also extremely amazing! A few words of Iger were resounded:

Angel wings must not be spread within a kilometer of the camp, and similarly, no undead bosses can be introduced within 500 meters of the camp once they are sensed. The camp will be immediately relocated to another area.

"There are so many rules."

Although Qin Qiao himself doesn't care, there is not much threat if he goes farther, and he will be fine with the wings of water when he comes back. But...... The people of the Black Prison Family, they are much more troublesome.

They must go to a place 500 meters away from the camp to fight monsters, in case they encounter underground zombies or bone dragons, and in distress, the camp cannot become their refuge at all; And......

With the little potion they carried, the ghost knows if they could swipe the crystal nucleus from the undead before the potion ran out, and the explosion rate here was obviously under the secret chamber of the dungeon and the ruins of Alex.

Qin's weak center of the earth sank again......

He began to have an awakening, an awareness of fighting alone in the underworld for a long time.

During this time, I hope there won't be much change outside.

Never mind. With Zilan, Lanyan Trouble, and Black Stone to take care of them, as well as Hua Hero and Black God, there shouldn't be anything wrong with the family......

Now the most important thing is leveling.

The sixth order has no bottleneck for promotion...... Although it takes a long time to go from level 50 to level 60, you can increase your speed in the underworld...... Hey, let's see if I can reach the sixth order before the Gods and Demons Continent enters the underworld. A shocking scene! The tide of undead, overwhelming the earth and bone dragons, formed a terrifying army of undead, obscuring a small valley to the sun and moon......

No one knows what's going on inside.

I saw countless skeletons, zombies, hellhounds, and vampires commotioning, blocking the passage less than twenty meters wide from the outside. The undead in the passage could not get in or out, roaring, spinning in place, and then suddenly being pushed into the passage a little more;

The bone dragons in the air gathered at least four or five hundred, overwhelmingly hovering over Xiao Gu, each time a bone dragon tried to dive down, but it was useless, above the Xiao Gu passage, a huge rock tens of meters long crossed like an axe. Happened to be right below where they were going to dive. It was also the place where the endless stream of undead advanced into it, forcing them to stop their dive. The flapping wings are back in the air.

Rise!!!

Hundreds of bone dragons repeatedly let out angry and impatient dragon groans......

However, there is no way to take the boulder below, and the passage under the boulder is too small to accommodate their huge bodies and the normal operation of their wings.

Watching hordes of undead advance into the passage beneath the boulder, toward the battlefield that exuded icy aura and magical fluctuations, there was no way but to protest with a roar.

The person under the boulder was none other than Qin Qiao......

This is the best safety training point that he finally established after spending a whole day yesterday by familiarizing himself with the environment within a 30-kilometer radius of the camp.

There are also a few good leveling points, but in comparison, it is better to brush alone alone, and there will be no invincible bosses such as lich troublemakers; Second, there will be no indestructible natural boulder on the head to intercept the aerial undead like the bone dragon;

Moreover, the various undead in this vicinity have been thoroughly explored by Qin Qiao, what kind of abilities the various undead have, and their resistance to the freezing attribute. As well as how much HP and how much experience there is, Qin Qiao already knows it well.

All he needs to do now is to stand under the boulder of the Xiaogu Passage, maintain the magic output of Ten Thousand Arrows and Ice Rain, and slowly brush up experience, during which he will command the little baby to dig out some crystal nuclei or other trophies from the countless undead bones...... And then. Whenever the army of the undead outside the valley gets impatient and ready to disperse, activate the angel wings and attract them back again.

Such an excellent environment for farming monsters is far more enjoyable than the five-meter-wide mountain path of the Eternal Peak, and the speed of farming experience is more than twice as fast, and it is also safer......

Although there were also high-level undead such as fifth-order mini-bosses and fifth-order big bosses during this period, Qin Qiao could always find out and consolidate his defense. Depending on the strength of the boss, dispatch the baby or use the ice potion to tide over the difficulty.

When he returned to the Iger camp with the harvest for the first time, Qin Qiao saw the extremely stunned and surprised expression of this sub-god-level archer. "How did you do that?"

Iger was surprised to take over the thirty-two undead crystal nuclei ranging from level 50 to level 63 that Qin Qiao had traded, as well as several crystal nuclei of fifth-order small bosses and big bosses. I can't believe it's real.

"Qin is weak! You really scared me, you know, even if I went out for a long time before, I could probably only scavenge for such a few crystal nuclei, you ...... You're level 50, oh no, level 51, tsk, you're progressing so fast. We didn't get a single crystal nucleus yesterday, and we thought you'd finally come to us to take over the mission...... It's unbelievable that you've been out and about for eight hours without even going back to camp to resupply. Egger's heartfelt praise made Qin weak, who was physically and mentally tired, feel a little more energetic:

"Yesterday I went to familiarize myself with the environment, and I just started work today, but I am afraid it will take more than half a month to rush to the sixth order."

"Take your time, the three of us have been here for decades. As long as we can get in touch with the Gods and Demons Continent, let alone half a month, we don't care if it's a few years. ”

Egger's education made Qin weak speechless for a while, and quickly pulled the topic back to the topic.

After asking Egger to exchange all the crystal nuclei for energy points, Qin Wan came to Youngor's tent with 67,920 energy points......

"What potion do you want?"

The conversation between Qin Wan and Egger had obviously reached the ears of this sixth-order alchemy thief, and I wondered if it was the ability that had been recognized by Youngor, and the latter's attitude and tone today were obviously much more relaxed than yesterday.

"Ice Elixir."

"If you exchange all of them for the Xuanbing Elixir, you can get thirteen bottles."

It is worthy of being a god-level alchemist, this kind of Xuanbing elixir that is rare in the Gods and Demons Continent. Youngor didn't even frown. It was as if he was talking about not a four-grade magic potion, but an ordinary large-scale magic potion.

Come to think of it. Qin Wan's heart moved:

"Oh no, you don't need to exchange all of them for the Ice Elixir, I'm thinking...... You should have Guardian Flasks, Speed Flasks, and Holy Potions here, right? ”

Hearing a series of fourth-order attribute potion names from the mouth of a fifth-order high-ranking warrior, Youngor's expression suddenly became softer, and he simply let go of the earth medicine tripod that was refining for the time being, and nodded to Qin Wan:

"I do have all of these potions you mentioned, but the divine elixir is a powerful recovery potion, unless it is paired with a great physical strength potion, otherwise you are a fifth-order water control master, and it will be a bit tyrannical to use."

"I suggest you take a bottle of speed potion and a bottle of guardian potion, when it is critical, with your water transformation technique, you can use it to escape ......"

"How about taking out 50,000 energy points to buy ten bottles of Xuanbing Elixir, and the remaining 7,920 energy points to replenish magic potions and healing potions?"

"Uh...... Yes, you can. Qin Qiao originally wanted to buy an extra bottle of Xuanbing Elixir, after all, the potion in the backpack did not consume much, and the energy value of 2,900 could completely make up for the previous consumption, but the NPC took the initiative to arrange a purchase plan for the player which he had never encountered, so he agreed to it.

"It's your potion."

Youngor traded Qin Qiao's order for the elixir and said:

"There is a potion that can inflict a divine purification effect on attacks, which can reduce the magic resistance of the undead more than the Ice Elixir, and cause more damage to the undead...... Next time you go to Walker Valley to level up, help me find a white ground fruit plant...... That kind of plant grows in the crevices of the cliffs, and you are an elementalist, and you have the ability to fly high and not be detected by the undead, and the elemental sense, should be able to help me find it. ”

"Its name is ...... Sacred fruit. ”

"Help me bring it back, refine the purification potion, and you can get a bottle."
