The black Orc fell to the ground with a bang, his mouth making a sound, his hands covering his throat, and a large amount of blood spilled from his fingers.

    Amazingly, his blood was light blue with many blue spots. A large amount of blood soon dyed his neck light blue and flowed to the grass.

    After the orc moved his hands to cover his face, he showed a miserable face. Renault just looked at it, and his stomach began to twitch. He quickly took a deep breath, suppressed the tumbling feeling in his stomach, and finally did not spit it out.

    At this time, the black Orc''s face, like a melting candle, had completely festered, and could only vaguely identify the five features. The blisters of large and small were all over the whole face. Many of the blisters had broken, and the yellow liquid was flowing all over the face.

    What is more terrifying is that one of his eyeballs has burst, revealing a startling hole, while the other eyeball is bulging high, becoming a pale.

    Obviously, the heat blinded his eyes!

    The main culprit of all this is the first ability evolved from the book of thermodynamics - [reverse heat conduction]!

    In any medium with uneven temperature, the heat will be transferred from the high temperature part to the low temperature part, which is the normal heat transfer.

    But in this world full of magic power, a magical thing has happened that [reverse heat conduction] can control the heat from the low-temperature part to the high-temperature part!

    Using this ability needs to consume a certain amount of magic power. The larger the control area is, the farther the distance is, the faster the heating rate is, the greater the magic power is consumed, and it grows exponentially. Therefore, due to the limitation of the total amount of magic power, this ability must have a limit.

    In addition, after the formation of high-temperature region, it also needs to consume less magic energy to maintain, and the consumption of magic energy is different with different temperatures.

    In addition, there is a great limitation of reverse heat conduction. If the target is a creature with a certain soul strength, the magic power will not be able to jump to them or near them.

    This is due to the interference of the soul energy field. The more powerful the life is, the greater the interference will be. Therefore, it is doomed that it cannot directly attack the enemy. It is just an auxiliary ability.

    [reverse heat conduction] at present, it can only work on gas, but cannot control the heat flow in liquid and solid.

    It is by using the reverse heat conduction that Renault unconsciously creates a small ultra-high temperature area. When the black Orc rushes over, it bumps into this area unprepared.

    So, in the air over 800 degrees, the black Orc''s face melted.

    Seeing more and more blood on the ground, the struggle of the black Orc became more and more weak. Renault was greatly relieved. In just a few seconds, he actually consumed nearly half of his magic power.

    At this point in the humid air, gradually appeared a vast white fog.

    In order to create a high-temperature area, [reverse heat conduction] draws a lot of heat from the surrounding area, forming a low-temperature area. After the water vapor is cooled, it condenses into white fog, so this phenomenon appears.

    A few seconds later, the black Orc finally stopped struggling and lay quietly in the pool of blood.

    The book of thermodynamics in Renault''s soul suddenly moves. The pages of the book are turning quickly, and the whole soul space begins to be turbulent.

    A faint shadow rises from the corpse of the black Orc and flies to Renault like lightning. The moment it touches him, it directly enters his body and soul space.

    The book of thermodynamics also quieted down, and the pages closed slowly.

    This is another magical function of the book of thermodynamics - absorbing "soul"!

    Renault called this shadow "soul". According to his own experience, it is actually just a collection of the residual mental power of the dead, and some magical powers are attached to the mental power, but there is no consciousness or memory in it.

    Under the influence of the mysterious book of thermodynamics, these residual mental power and magic power can be turned into a dark shadow, so that Renault can see directly with his naked eye.

    The existence time of "soul" is extremely short. Once the virtual shadow appears, it begins to dissipate quickly. In a short time, it will completely disappear in the air. If the "soul" is more intense, it will exist for a little longer.

    There is a certain distance limit for this absorption. The farther the distance is, the less energy the absorption knife has. This is also related to the strength of "soul". The higher the strength is, the more attractive the book of thermodynamics will be to the soul.

    For the soul of ordinary black orcs, it can absorb almost all the energy within 3 meters. After 15 meters, it can hardly absorb any energy.

    After the "soul" was absorbed by the book of thermodynamics, Renault felt his magic power and spiritual power, and then he was stunned.

    He found two extremely incredible places.

    First of all, his magic power recovered a little.

    In other words, the book of thermodynamics even has its own special effect of "mending the devil"! Although the amount of recovery is relatively small, it is also enough.

    Under normal circumstances, once the magic power is consumed, in addition to some extremely precious magic potions, the recovery of magic power can only rely on the body to slowly absorb the free magic power from the outside world, and the recovery time is quite long.It will take at least an hour for Renault to recover this magic power from the book of thermodynamics.

    Secondly, his mental power and magic power limit were both increased a little.

    If you rely on normal cultivation, how long will it take to improve this little mental power and magic power? At least half a month! But with the book of thermodynamics, Renault only needs to kill a black ORC.

    This also means that as long as enough black orcs are killed, Renault can raise his magic power and mental power to the level of invincibility.

    Only in this way, the book of thermodynamics can be called the existence of artifact.

    After a while of joy, Renault began to smile bitterly. At the moment, even he could not help feeling that he was a devil who liked to devour his soul.

    He really did not understand why a good book engineering thermodynamics turned into a strange devil''s book after crossing the world.

    It is for this reason that the aboriginal "Renault" called him "the devil from the alien world" and imprisoned him for a whole month.

    At this time, a dense sound of footsteps came from the distance, and the sound was getting closer and closer. It was obvious that they were coming for Renault.

    Then there was a roar, a clash of blades, and then there was a clear scream, which was filled with great fear and panic.

    It''s Angela!

    The black orcs are after her!
