[carving techniques of golden fir], [how to judge weather changes with the naked eye], [basic refining of granulated sugar], [smelting of copper metal], [gem appreciation], [basic education of ELF children], [what to do with barren land?], [why is the sea a little salty?]


    A lot of inexplicable knowledge is being transferred into Olga''s brain in batches.


    It can be said that just looking at their names, most professionals don''t want to see them again.


    This pile of ghosts has no effect on them and even most of their existence.


    But Olga didn''t mind this little problem.


    Because no matter whether they have eggs or not, they are explaining some truth or knowledge in the world.


    Even if that truth or knowledge is wrong, it can be used as a reference.


    So it''s not worthless.


    It just turned into nutrition to improve his knowledge reserve.


    Even if that knowledge is strange.


    Others on this floor are unaware of this and are still doing their own things there.


    Their strength is too low to be aware of Olga''s spiritual tentacles.


    Every three seconds, when the whole floor begins to scan for abnormal movements by some hidden fluctuation, Olga''s spiritual tentacle will be retracted at the right time to avoid being discovered by the tower spirit.


    Although he didn''t know whether that wave could detect his mental power or not.


    But now he doesn''t want to try.


    At least until his goal is achieved.


    If something really goes wrong, in order to cover up the matter, he can only destroy this place by violence and clear all the records about him here.


    In the face of the city''s possible hidden strong, he has little confidence to do things well.


    Don''t get me wrong.


    The lack of confidence here does not mean the lack of confidence to win, but the lack of confidence to kill the other party and the witnesses before the other party spreads the news.


    It is equivalent to not sure to remove the finger on his message sending button before cutting the other party to death.


    In this world, even if it is the lower boundary of the real body of the gods, he has the ability to compete.


    I don''t want to make big news. I just want to experiment with the [dead poisoning scheme of mixed eating in the world] that is more in line with his goal. There is no one I''m really afraid of.


    -----


    Three days later.


    An apprentice wearing the apprentice''s robe of a magic school poked his friend''s waist. His face was strange and sighed at him: "what strange books that guy reads..."


    “？”


    His friend raised his head a little inexplicably and looked at the person he said.


    In an instant, among dozens of people in that area, Olga was very striking.


    At the first glance, I felt that Olga''s temperament and appearance were extraordinary. At first glance, he was a strong man at the master level.


    The serious expression was as serious and solemn as looking at the difficult experiment.


    Then the second eye was to see the book in his hand, [old hen''s high-yield egg feed formula].


    "What?"


    "What the hell is [the old hen''s high-yield egg feed formula]?"


    That feeling was like seeing the dean of the mage college put a layer of baby crotch cloth on the outside of the mage''s robe, which immediately made him unacceptable.


    "Big brother, why do you think this thing is important to you?"


    "And still with such a serious expression!"


    Rows of question marks immediately appeared in his head.


    His friend added in a low voice: "not only this [the high-yield egg feed formula of the old hen], but also his last book is [the beauty of human body sculpture], the last book is [what kind of soil is better when people are dying of hunger], and the last book is [the breeding period of karacha lizard]..."


    "Hiss..."


    After hearing this, he suddenly thought of his erudite tutors who seemed to know everything. He took a breath of cold breath and felt that he had realized the common ground of the strong.


    "The world of the strong is so comprehensive in Chengdu?"


    At the thought of this situation, he felt that his IQ might not meet that requirement, and his heart began to lose a little.


    His friend didn''t know that the other party would have such an idea of mental retardation. He just sighed there: "this big man''s interest is a little too extensive. He actually picked up a [sow postpartum care manual]!"


    "He opened it! He looked! And he was serious!! how did he do it!!!"


    In the end, his face was even ferocious.


    He could not imagine Olga''s unattainable existence at first sight. What kind of state of mind would he have to look at it calmly and seriously.


    What he didn''t know was that the things in Olga''s hand were nothing wonderful in the books he read. He didn''t let go of [how to see things with left and right eyes respectively], [knife and fork Symphony], [girlfriend of good sisters], [domineering dwarfs love magic dragons] and [how ordinary green orcs are].


    It''s a mistake to kill.


    It can be called extreme madness.


    Even that disgusting thing can be seen calmly!


    ------


    A forest hundreds of kilometers from Augustus.


    A bald man was carrying someone who was one of the two noble brothers who had appeared not long ago. Looking at a wall in the cave in front of him, his face was extremely serious and asked, "are you sure the treasure is here?"


    "Sure, sure, how dare I lie to you!"


    Judging from the words, this is the cowardly one.


    Nodded with satisfaction, the strong man said with a grim smile: "well, in that case, you can lead the way. If you don''t want to accompany your brother, you''d better not play any tricks."


    Thinking of his brother who died miserably and those mercenaries who died miserably, the cowardly man shivered and explained: "my Lord, it''s not that I don''t want to lead the way, but that this place is bounded by my ancestors. Unless I can pass the test, I will die in it as soon as I enter!


    It''s a small problem that I''m dead. It''s not good to drag you down! "


    Looking at his despairing appearance, the bald man slapped him without saying a word!


    "Fool! After you left, we found some information about this treasure in other parts of your house. The so-called erasure mechanism is actually frightening. It is only used to test the courage of your descendants!"


    "Ah?"


    The cowardly man was stunned immediately and obviously didn''t think of this possibility.


    But after careful consideration, I think it is very reasonable. After all, what mentality should our ancestors have before they can test their descendants with deadly things?


    So he boldly walked over, cut a wound in his hand with a knife and sprinkled blood on the wall!


    "Buzzing..."


    In the slight vibration, a door leaf appeared there.


    The bald man was immediately overjoyed, waved to several of his companions, and then pushed the cowardly man through the door.


    This guy can''t lose it. It''s an amulet inside!


    After entering the door.


    The oncoming fire was a strong flame, and the bald man looked at its strong power.


    Not surprised but smiling, he raised his hand and blocked it with the cowardly man in his hand.


    According to the design mechanism, this barrier can only hurt the inheritor and can''t kill him at all, so you can easily pass the customs with this guy as a shield!


    The next moment, look at what has become eight cooked in your hand.


    The smile on his face froze in the face of the overwhelming fire waves around him.


    "Oh..."
