Ning Hu and Meng Qinghua, who rushed to hear the news, refused Meng Ruoyu's kind move to bandage his wounds, Zhang Hang returned to the room silently, sat on the ground and silently looked at Wu Junsheng's blood on the ground.

Zhang Hang's terrifying self-healing ability has caused the wound on his leg to begin to heal and no longer bleed.

In the room, Zhang Hang sat quietly like an old monk, and outside the door, Meng Ruoyu wandered in the corridor worriedly.

A full hour passed, and just when Meng Ruoyu couldn't help but push the door into the room to take a look, the door slowly opened, and a familiar smiling face appeared in front of Meng Ruoyu's eyes.

"What are you doing, why don't you recharge your energy and hang around at my door?" Zhang Hang changed into new clothes, and his tone was as cynical as usual, as if everything that had just happened was an illusion.

"Are your injuries okay?" Meng Ruoyu asked with concern.

Zhang Hang smiled and stretched out his hand to pat the injured thigh: "Do you know what steel and iron bones are? I am Sun Dasheng alive, just this little injury, five minutes will be fine." ”

"Phew, don't stink, the steel and iron bones are still bleeding?" Seeing Zhang Hang slap the wound "popping", there was no trace of pain on his face, it didn't seem to be a fake, and Meng Ruoyu was also a little relieved.

"What's going on, who hurt you?" Meng Ruoyu has been focused on study and research since she was a child, and under Meng Jingshi's intentional "care", Meng Ruoyu is not very clear about the Meng family's business and many things, so she naturally can't recognize Cui Hongsheng's father and daughter.

"Don't mention it again, it's all over, you come in, I have something I want to ask you. Zhang Hang dodged and let Meng Ruoyu in.

Meng Ruoyu walked into the room a little confused, sat on the sofa, and the shocking blood stains on the ground had been cleaned up by Zhang Hang, without a trace.

"What are you going to ask?" Meng Ruoyu asked.

"I know that the institute has a confidentiality agreement, so I don't embarrass you, I ask, you don't need to answer, just look me in the eye. Zhang Hang restrained his smile and looked at Meng Ruoyu seriously and said.

"Good ......" Meng Ruoyu had never seen Zhang Hang like this, some were afraid, some were surprised, and some indescribable emotions filled Meng Ruoyu's mind.

"You're studying weapons, right?" Zhang Hang stretched out a hand and put it on Meng Ruoyu's shoulder, and asked softly with Meng Ruoyu's eyes.

Meng Ruoyu didn't make a sound, Zhang Hang's eyes seemed to have magic power in front of his eyes, Meng Ruoyu was in a trance, and nodded slightly involuntarily.

"What type of weapon?" asked Zhang Hang in a bewildering voice.

Meng Ruoyu looked at Zhang Hang blankly, as if he was very tired, slowly closed his eyes, but replied to Zhang Hang's words: "Nano covering weapon coating, it has a wide range of uses, at this stage, the nano covering of cold weapons has been successfully tested, and it will be sent to the capital for thermal weapon testing after the approval of the General Academy." ”

Zhang Hang listened carefully to Meng Ruoyu's muttered words, although Zhang Hang couldn't use his internal force, his spiritual power was not affected, although Zhang Hang didn't know how to cultivate his spiritual power, but thousands of years passed, although Zhang Hang's spiritual power was not as strong as the internal force cultivation, it was not something that ordinary people could resist, and easily hypnotized Meng Ruoyu.

"Why did you want to do this research?" Zhang continued.

"Why? for ...... What?" Meng Ruoyu's body suddenly tensed, her brows furrowed, and she seemed to be extremely resistant to Zhang Hang's question.

Zhang Hang had no choice but to withdraw his spiritual power, with his own spiritual power realm, if he didn't care about Meng Ruoyu's life and death, and forcibly asked, Meng Ruoyu would not be able to stop it, but in that case, once the hypnosis ended, Meng Ruoyu would become a complete idiot.

"Hey, why are you asleep? I'm asking you!" Zhang Hang shook Meng Ruoyu's shoulder and shouted loudly.

Meng Ruoyu trembled, her tightly closed eyes slowly opened, and she looked at Zhang Hang in front of her suspiciously.

"I asked you if you would go to the institute in the afternoon, why are you still asleep? If you don't sleep well, you can go back to your room and sleep. Zhang Hang pretended to complain as if nothing happened.
