Nameless island.


    Poisonous pink butterfly population territory.


    An underground river appeared in Aoki''s sight.


    "An underground river?" Aoki frowned and looked at the underground river.


    This is different from what he imagined. Originally, he thought it would be an energy crystal ore or an energy body that dissipated, so that the elves here can absorb these dissipated energy only through breathing, so that they can condense energy crystals in the body.


    Aoki went to the hole and jumped directly.


    The elves looked at the action of Aoki and jumped down together.


    When it was about to land, the green wood suspended in mid air, and then slowly fell to the ground.


    The super power of the dull beast played a role and put the green wood and all elves down safely.


    "The soil here is very soft. It seems that it is because of the underground river." Aoki squatted down, grabbed a handful of soil with his hand and put it in the palm of his hand.


    Qingmu put down the soil in his hand, went to the dark river, Yao some water with his hand, put it on the tip of his nose and smelled it.


    There is a faint fragrance and nothing special.


    "Chip, scan the water. It doesn''t feel so simple." Aoki ordered the chip.


    After a moment of silence, the chip showed the data in front of Aoki.


    Aoki looked at the analysis report on the water in the underground river and was surprised.


    "These waters actually contain a small amount of energy fluctuations. So the energy crystals in the poisonous Pink Butterfly really have something to do with the river?"


    "But in a small island on the sea, there is an underground river, and the water is still fresh water?"


    Aoki doesn''t understand.


    If the water is seawater, Aoki can accept it, but there is an underground river formed by fresh water in the seawater.


    Is it related to the small lake in the center of the lake?


    No wonder there is a tropical dragon in the middle of the lake. Not all elves can go to the lake to drink water.


    And there is still a distance from the lake. Is it too troublesome for so many poisonous Pink Butterflies to go to the lake to drink water?


    The trees on the island can grow so big, I''m afraid it has something to do with the underground river.


    The elves on the island, after eating these plants, energy gradually precipitated in their bodies.


    Slowly combine with the original energy attributes in their bodies and become attribute energy crystals one by one.


    Those medium-sized energy crystals should be because these elves live for a long time. When the energy condenses in the body for a long time, it condenses into higher quality energy crystals.


    This also explains why such an island can feed so many elves.


    The level of these elves is not low, with an average of more than 20.


    It turns out that everything is because of this underground river.


    So where does this underground river come from?


    Why does this dark river carry energy?


    Aoki''s doubts were solved one by one, but at the same time, new doubts appeared in his mind.


    After taking a look at both ends of the dark river, Aoki was considering whether to explore it.


    Is it because of this hidden river that several large ethnic groups on this island survived?


    Is it possible that the elves in each group should have the ability to crystallize in their bodies?


    Although not all the poisonous Pink Butterflies have been cleaned up, the rest are relatively low-grade and young, and there will be no energy crystals in the body.


    But such a group, with nearly 600 or 700 poisonous Pink Butterflies, provided Aoki with 178 small energy crystals and 12 medium-sized energy crystals.


    If all these energy crystals are used by the scorpion, regardless of the consequences, resistance, energy loss and other things, the scorpion may be upgraded to level 278 or above in one day.


    Of course, after several days of fighting, although not as the main force, the pintail scorpion picks up leaks nearby, or simply fights with the weak poisonous pink butterfly. Now its level has reached level 17.


    In other words, nearly 200 energy crystals can raise the Scorpion by ten levels.


    What if for those newly hatched elves? Whether the level can be promoted faster.


    It will soon be able to cross the weak period just after hatching.


    Moreover, it can not only improve the level, but also slightly improve the qualification of elves when used more.


    Pintail scorpion is a light cyan qualification, so it needs nearly 10000 small energy crystals to complete the transformation of his qualification.


    What if it''s light green? What about green qualification? Does it require much less?


    You know, not all of Aoki''s elves have achieved cyan qualification.


    The big milk jar with light green qualification and the dark crow with green qualification are dark green, even if they are the most powerful dumb animals now.


    Can you use these energy crystals to let the elves upgrade their qualifications?


    The more you think about it, the more likely it is. Aoki is a little excited.


    Of course, the energy crystals obtained now are the energy crystals of insect system and poison system, and have no effect on improving the qualification of other elves.


    But isn''t there an underground river here?


    As long as we find the reason why this underground river contains energy, we may be able to find items that can promote their qualifications.


    After understanding, Aoki directly took out the metal torch used in the gopher cave from the ring.


    After filling up the oil and lighting the fire, Qingmu walked in slowly along the direction of the water flow.


    The soil on the ground is too wet, because when the underground river flows, some water is often blocked by the rocks, so that the water spray in the water flow is splashed to the bank, so the soil is very wet.


    Even a little muddy.


    Aoki''s shoes have been stained with some soil.


    However, according to the current situation, in fact, these soils should also contain a lot of energy. If they are collected for planting or planting some precious medicinal materials, I''m afraid the efficacy of these medicinal materials will be particularly good, and the growth rate may double.


    Of course, the premise is that the energy in the soil is not absorbed.


    As he took the elves forward, some thirsty elves also directly lay down by the river and drank some water.


    I just feel very cool and sweet. Even before the battle, my physical fatigue has been reduced.


    The dull beast went too far into the water and followed Qingmu with a leisurely look. The other elves looked very envious.


    Aoki also took out some bottles and filled some water.


    Although the energy in the water is very dispersed, the effect is still good. If you use the water next time you make the energy box, the effect of the energy box should be better.
