"Let''s go human, since you''ve all come in, I''ll take you to see some good things." Elder Rat said proudly.

    "What?" he asked curiously.

    "You''ll know when it arrives."

    Then they turned right and left through the areas, and came to the innermost, in front of a silver door.

    I saw Elder Rat enter a series of passwords, and the door opened.

    Then they went in.

    "This is our genetic research institute." Elder Rat said proudly.

    "We humans have it too."

    Long Ritian glanced at it and didn''t think there was anything special about it.

    "Those of you humans are still in the initial stage."

    After the elder rat finished saying this, he walked up to a blue-eyed white mouse.

    "Professor, how''s the genetic potion research going?" the elder rat asked the white mouse.

    "Elder, the experiment has just been completed." The white mouse turned around and glanced at Long Ritian with his glasses before speaking slowly to the elder.

    "Okay, give me a bottle and I''ll try it."

    "Well, there happens to be a bottle here."

    Professor Rat took out a blue test-tube potion from the table and handed it to Elder Rat.

    "Human, let me show you our century of research."

    The elder rat said to Long Ritian and drank the potion.

    I saw Elder Mouse''s body began to change, some hairs began to fall out and turned into white patches, and his limbs also began to change, gradually becoming stronger.

    Then it turned into the shape of human hands and feet, and then the face, the long nose and lips slowly retracted, the eyes gradually enlarged, and gradually, a human face appeared.

    Ten minutes later, an unclothed, white-haired, 1.4 meter tall old man with pale blue eyes appeared in front of him.

    "This…"

    Long Ritian watched this scene in disbelief.

    "Don''t be surprised, this is the humanized gene potion that we have studied for a century in order to obtain materials in human society. The purpose is to freely enter and exit the human world. We are still blue-eyed mice."

    I saw Elder Mouse say slowly, his hands and feet were still moving, and he seemed to be adapting to this body.

    "I have to say, you guys are really amazing." Long Ritian sighed.

    "If you are given dinosaur genes now, can you make a dinosaur gene potion?"

    "Whatever is given to us, as long as we have the material, we can make it."

    Professor Mouse said confidently.

    Long Ritian nodded when he heard this.

    When he came in, he saw that except for the door, the other computer machines were very old, probably second-hand computers they had stolen from the garbage dump or other grounds.

    Then they were modified to become what it is now.

    "Professor, how much of this potion can be made now?" Elder Rat looked at the professor and asked.

    "Elder, the materials are limited now, so only twenty bottles have been made." The professor replied.

    "Too little..."

    Elder Rat frowned.

    "I can help you." Long Ritian smiled aside.

    "You? What''s your purpose?" asked the elder rat.

    "The purpose is very simple. All the money you earn belongs to me. Anyway, you just want to go back to your planet, don''t you? It''s useless to ask for that much money."

    Long Ritian laughed.

    "How do we know if we can trust you," said Professor Mouse.

    "Oh, so what?"

    "Roar…"

    As soon as Long Ritian finished speaking, his body began to change, his skin hardened and darkened, and a few seconds later, a small Tyrannosaurus Rex appeared in front of them.

    "Dinosaur?"

    Elder Rat and the professor were shocked.

    "No, it''s a genetic man who drank the Tyrannosaurus Rex gene potion," the professor said after taking a serious look.

    "What if this happens again?" said the dinosaur incarnated by Long Ritian.

    I saw the thunder light flickering in the huge mouth of the Tyrannosaurus Rex, and a thunder ball appeared.

    "This…"

    The elders and the two mice felt the aura of destruction, and their legs were a little weak.

    "Are you an alien or are we aliens?" Elder Rat said dumbly.

    "Ha ha…"

    After Long Ritian smiled, he turned back into a human form.
