Caesar accidentally glanced at his tail in the endoscope. He felt that the thorn hammer growing at the end of the tail played a slightly chicken rib in actual combat. It was only suitable for scope beating. In terms of single attack, the hammer was not as powerful as his claws and teeth.

    If it can grow into the shape of the grapple used by those adventurers before and be used for long-distance grasping, the black dragon thinks it will have better effect and wider applicability.

    God said to have light, so there was light. Caesar thought that the thorn hammer at the end of the tail could become a claw hook better, so under his gaze, a gap broke out from the inside out at the horny center of the hammer, which was quickly divided into four petals.

    Then, they began to change rapidly, the surrounding was uneven, and the gap caused by division became neat, like being polished, and then began to refine and become more sharp.

    Finally, the tail end becomes a claw hook.

    Then, countless blood vessels, muscles and various complex nervous systems began to form and fill the originally uncomplicated tail end, and the sense of control connected Caesar''s mind.

    "Bang Bang..."

    He tried to control the tail claws to grasp a few times. The hook toes of the tail collided with each other, making a metal sound and bursting into sparks. His strength was not bad.

    "Yes."

    Caesar gave a smack of admiration, curled his tail in front of him, held it with his right forepaw, and looked carefully at the newborn tail end organ.

    The outside of the tail claw is surrounded by black cuticle, but there should be nerve structure in it. The shape is like an open dragon claw, ferocious and grotesque.

    Caesar knew the power of the black jade reward.

    However, he thought that the lethality of the tail claw was not as good as that of the tail hammer. Can the tail end be changed into a double joint composite structure, so that it can become hammer like when clenched and claw like when loosened, killing two birds with one stone.

    Caesar sketched in his mind the complex form of his imagination.

    At the next moment, the tail end just turned into a claw changes again. At its hook toe, a double joint bone structure soon grows. A small gap appears in the middle of the curved hook toe, and the inner side immediately becomes vertical, which can fit seamlessly with each other.

    In this way, when the tail hammer is needed, Caesar only needs to lock his two joints, so they can close to each other and form a diamond structure. He can use the bulge on the joint as a blunt angle, or the top tip as a sharp spike.

    When it needs to be grasped, Caesar can control the movement of both joints to open, making it look like a tail claw.

    This kind of multifunctional organ can only be achieved with a double joint composite structure. If there is only one joint, the tail claw will lose its grasping efficiency. Because the inner side is vertical, it can only spread or close straight (the same is true when Caesar only controls one joint).

    While he was studying the newborn tail claw tirelessly, the guy keenly found that his body size decreased, and his strength and speed decreased slightly.

    This change was so subtle that it was even difficult to find it without accurate measurement, but Caesar noticed it carefully.

    "Conservation of mass." he thought that the tail claw did not grow out of thin air. It absorbed the resources of other parts of the body.

    For a simple example, Caesar now has a comprehensive body point of ten. After he points a little on the tail claw, the value left to other parts of the body naturally only has nine points.

    This is reasonable, and Heilong is not surprised.

    In the final analysis, the reward is only a black jade achievement, which is far from breaking the basic operating rules of the world.

    "In this case, my defense ability is strong enough now. What I need is strength."

    Caesar thought, "weaken the hardness and thickness of the scale and strengthen its strength."

    He waited and his body didn''t respond.

    "Well -" after discovering this problem, the black dragon pondered for a while and quickly responded: "I see."

    The reward is the independent deployment module, rather than a transformation system provided with him, which means that all deployment requires him to do it himself, figure out the shape, function and structure of the transformation part in his mind, and then outline the specific drawings like manufacturing tail claws, and refit them step by step.

    General concepts and instructions do not work.

    "If you want to strengthen your strength, you should first increase your muscles, increase the muscles of biceps brachii and forearm muscles, um... Tail and waist muscles should also be strengthened."

    Caesar thought, with the endoscope ability that had been explored before, began to deploy: "here, here, and here..."

    Sure enough, under the careful conception and outline, his muscles began to grow, his limbs became longer and stronger, and his strength rose upward.

    At the same time, his thick neck became thinner, and the thickness and hardness of scales decreased to a certain extent, which also involved the scope of material transformation.

    Caesar tried a little and stopped mixing.

    After all, there are still a large group of people waiting outside. If you see the black dragon changing suddenly, I don''t know what to think.

    Now that he has made clear this ability, Caesar is ready to leave. Now the time is not appropriate. There is enough time for him to adjust slowly in the future.

    Caesar is quite satisfied with the new black jade reward. The playability of this "fully adjustable autonomous control module" is very high, so that he can adjust and refit his body at will. If this guy plays special enough, he can transfer himself from a black dragon to a red dragon or a Golden Dragon... It is not impossible to even turn into an abyss demon.

    Of course, Caesar will never do this at this stage. He takes good care of his body enough. He must try his newly acquired ability carefully for fear that he will be damaged by careless modification.

    Thinking, Caesar withdrew from the dark space and left the dark dream.

    After blurring, the eyes returned to clarity. After a short stagnation, everything that had been fixed came back to life. The creatures continued to act for the last second, and the new wind continued to spread.

    Caesar also maintained the action of showing his teeth and roaring. He was slightly retarded by the abrupt transformation of time and space and the body that needed to be readjusted after adjustment.

    However, when Caesar was Caesar, he quickly reacted, twirled Luna''s hair with the tip of his claws to comfort her, glanced at the jackals, and then turned his head to see the current state of the orcs.

    Contrary to his expectation, when Caesar looked back, he found that there were only four hundred orcs left, all facing him and kneeling on one knee.

    This is the first time Caesar saw the orcs make such a move. According to Luna, even when the orc empire was at its peak, in the face of the orc emperor, it was enough for people to salute with one hand hammer, and the orc etiquette was so far.

    "Please avenge us, Lord ortolenso."

    Garh, the leader of the stone crow clan, knelt at the front of the team. This strong ORC with a body size of more than two meters and the same as the iron tower, now bent deeply and buried his head in the shadow cast by the Black Dragon: "we would like to be your family members, servants and slaves. Please avenge us, sir."

    The other orcs knelt in silence, sweat and tears dripping to the ground, silent.

    "I will."

    The black dragon looked at them and whispered, "Sylvia, Roy. No matter where they hide in the future, I will find them and cut them alive to avenge Steve."

    He assured the orcs that he was also swearing to himself.

    "But not now."

    Caesar shook his head, drove away the anger rising again, and glanced at the orcs and jackals: "who can tell me where this is?"
