Once again, he focused on the exchange book and looked for the skills he needed.

    "I want to exchange these two skills," Aoki said, pointing to the skills in the exchange book.

    The booklet reads:

    Skill: hold

    Properties: General

    Classification: Change

    Power: 0

    Note: form a protective cover around the body to completely resist the opponent''s attack within a certain period of time. It cannot be used continuously. Use it once for 10 minutes.

    Price: 5000 points

    Skill: Double

    Properties: General

    Classification: Change

    Power: 0

    Explanation: as like as two peas in the same way, you can reduce your blood volume and take an attack for yourself.

    Price: 4000 points

    The two skills add up to 9000 points, which shows that the price of skills is very high. This time, Aoki was very lucky and got a precious green Elf egg. If not, I don''t know if I can exchange a hold skill when I leave this test.

    Looking at Aoki''s expressionless exchange of two skills with such high prices, the exchange personnel really didn''t know how to cherish the points.

    He muttered in his heart, but the movement on his hand kept. He opened the safe where piles of skills were stored, took out two skill CDs emitting white light, and carefully handed them to Qingmu.

    This is the difference between people''s ideas. For Aoki, it''s just some points. If you don''t change it into effective combat power, it''s like a pile of useless data in your hand. Only by converting points into combat effectiveness, this is the highest value of points.

    As long as the dark crow has mastered the two very useful skills of holding and doubles, the life-saving ability of the dark crow has been improved by more than two levels. Coupled with the originally fast speed, it can be said that the dark crow has the power of a war as long as it doesn''t encounter opponents with very different levels.

    There are 11000 points in his hand. Aoki is going to exchange evil skills for the dark crow,

    Turn over the page full of general skills and directly turn to the evil skills column. Without much thinking, Aoki directly exchanged the evil wave skill and spent 3000 points.

    As the output skill of the evil system, the power of evil wave is OK, and the hit rate is very high. The collateral effect of the skill itself can be good, and there is a certain chance to make the opponent fall into a state of timidity.

    With 8000 points left, Aoki thought about it and decided to put it first. After exchanging three skills at once, plus the harsh sound skill CD, the dark crow can learn four skills at once.

    Although we can continue to exchange skills, we can''t eat fat at one breath. There is a big gap between just learning and mastering the same skill. The difficulty of mastering the four skills of the dark crow is not low. What we need to do now is not to learn more skills, but to master all the skills we have learned and strive to achieve the degree of confidence.

    "Give me another training device that can freely control the weight. For the flying elves, the upper weight limit is 50 kg." after thinking about it, Aoki exchanged another tool to facilitate the usual training of dark crows.

    During this time, the dark crow used wood as a weight-bearing tool. Although it is good to use, you can''t find a heavier wood to tie to the dark crow''s wings after getting used to this weight. The scientists of the simple rocket team have a mature research achievement, which is said to be a learning device for reference. Although they did not get the effect of the learning device in the end, they occasionally made a device that can freely control the weight. Finally, it became one of various training devices in the rocket team, which was a good invention.

    This kind of weight-bearing device does not use many technologies, so the price is not very high. For a device with a maximum limit of 50 kg, the price is 200 points.

    "Ten more super balls." put everything in his belt and Aoki exchanged ten more super balls. Each ball is worth 50 points, a total of 500 points.

    Although Aoki didn''t intend to accept other elves on the island, after talking with the mysterious man today, he still felt it necessary to start cultivating other elves. Today''s final trial is not difficult for Aoki. Except that gujia and two or three others are a little tricky, others are just minions.

    But now the situation is that Aoki not only needs to face the final test, but also needs to face some small things said by the mysterious man before the final test. For mysterious people, it is already a matter, even a small matter, but compared with Aoki, it may be a difficult event. So it is imperative to cultivate other elves.

    Put away ten super balls and give the magnetic card representing your identity to the Redeemer. I saw him brush together and save all the remaining 7200 points in the card. The exchange cost a total of 12700 points, and 100 points is the cost of detecting elf eggs.

    Walking to the corner of the exchange, a machine stood alone, and the elf learned the machine.

    The elf learning machine can directly import the skills on the skill CD into the ELF''s mind and learn this skill directly. This is also one of the most high-end technologies in this Baoke dream world.

    The use of the elf learning device is free, but Aoki didn''t use the skill CD first, but took out a super ball and replaced the original ordinary ball of the dark crow with this super ball. For the space inside the elf ball, it is also a change from a single apartment to a luxury house.

    Although the dark crow has hardly stayed in the elf ball, with money, of course, it is first to change the dark crow for a good place to stay, even if he doesn''t often go to get accommodation.

    Put the dark Raven into the super ball just replaced, put it on the groove during the elf learning period, take out the skill discs from the storage space one by one, and turn on the device to use one by one.

    Fortunately, it''s evening. There is no one else in the exchange office except Aoki and the exchange staff. Otherwise, seeing Aoki''s extravagant use all four skills at once, I''m afraid he will scold and waste!

    For other elves, gluttony may be a waste. However, it is only a matter of time for dark crows with medium green qualifications to master these skills.

    After using the skill CD, it becomes an ordinary CD, which is worthless.

    The use time of each skill CD is one minute. After all use, Aoki released the dark crow in the super ball.

    "Ga!" the dark crow came and immediately shook his wings and flew up. For it, which hardly gets into the elf ball, although the elf ball is spacious, it is not comfortable outside.

    He smiled and touched the feathers of the dark crow. Aoki gently asked, "how? Have you learned it?" although he knew it was impossible to learn, he still asked.

    "Ga! GA!" the dark crow immediately nodded. He felt very magical. He didn''t know his skills at all. The method suddenly appeared in his head, as if he had learned it by nature.

    "How? Have you learned?" Aoki stood aside and asked with a smile.

    As if to prove that he had learned it, the dark crow narrowed his eyes and a light green energy mask appeared, wrapping his whole body. The light green energy mask lasted about two seconds and gradually dissipated.

    "Hold the skill." Aoki''s eyes brightened. Aoki is very familiar with holding the skill. When the strength reaches a certain level, almost every elf must learn to hold the skill. Such a precious and efficient life protection skill can be unconditionally immune to damage. It''s not too much to say that it is a life protection skill.

    Seeing that the light green energy mask lasted only such a short time, the dark crow found that it could not be released when he wanted to use it again.

    Reaching out to stop the dark crow ready to release again, he smiled and said, "this skill can only be used once in ten minutes. Let''s go and go back."

    Immediately, he took the dark crow and slowly left the exchange house into the dark night.

    The staff of the exchange house looked at Aoki''s back and couldn''t help saying, "what a lucky boy! He was taken in by the adult." but what he didn''t know was that Aoki was more familiar with the mysterious man''s position and army than him. I just don''t know whether it will be a blessing or a curse this time.

    In the Rockets base, there have always been 300 rooms for the trainees, which will never change. On the door of each room, there is a number corresponding to everyone''s number.

    Walking in the base at night, I almost saw a figure. Only the shadow of green wood and dark crow was left. Under the moonlight, the shadow grew longer and longer.

    The room arrangement of the dormitory was very regular, and Aoki soon found his own room.

    Although I haven''t come to live once, the room is still relatively clean, with a simple single bed, a small desk and a chair. This is all the things in the dormitory. It''s relatively simple, but for Qingmu who has been living outside, it''s enough to have a soft bed.

    He locked the door behind him and Aoki lay on the bed. The softness he had not seen for a long time made Aoki moan.

    The dark crow also came to the human room for the first time and began to fly curiously in the room.

    In the middle room of the Rockets, the top officer of the trial and the chief instructor of the Rockets, viper''s office, are still the same two people sitting at their desks.

    The Viper held a precious luxury ball in his hand, gently wiped the invisible dust on the ball with a handkerchief, looked at the luxury ball like a lover in love, and finally said to himself, "I heard that a boy interested you?"

    The mysterious man sitting opposite was hidden in his black robe. Like an old monk, he did not move or answer the questions of the poisonous snake.
