"Next, we have invited Professor Yang to give a keynote speech to introduce the principle of this newly developed 'invisibility cloak' to everyone here in detail." After the host finished speaking, he retreated to the side of the stage, and several other members of the research team also stepped down from the stage one after another and took their seats in the audience.

Mu Qingcheng watched the magical demonstration on the stage very intently just now, completely ignoring Cheng Yijie beside him, and then turned his head, only to find that he had disappeared at some point, did he feel that the press conference was too boring and couldn't sit still?

She was in a trance for a while, and after calming down, she saw Yang Ru re-onto the stage, took out a USB flash drive from her jacket pocket, and walked towards the podium.

Just as Yang Ru was gradually approaching the podium, an astonishing scene occurred. Cheng Yijie suddenly rushed to the stage, quickly pushed Yang Ru away, and the two fell together. Almost at the same time, there was a loud "bang", and the microphone placed on the podium exploded, and the lectern and the laptop on it were blown to pieces.

Mu Qingcheng suddenly couldn't see anything clearly, no ideological consciousness was gone, she only felt that deep in her heart, a terrifying fear and pain violently eroded every nerve in her. She jumped up, blindly trying to rush out of the audience, onto the stage, to her uncle.

The entire stage was shrouded in a cloud of smoke, which quickly spread, and the people in the academic lecture hall panicked and fled in all directions. Mu Qingcheng was coerced in the crowd and pushed and squeezed, but desperately went in the opposite direction. She tried her best, went on a rampage, and finally broke through the encirclement and ran to the stage. The podium was on the left side of the stage, and several staff members and the host on the side were injured, groaning in pain and waiting for rescue.

"Uncle—uncle—" The smoke choked and suffocated her, and she cried out in a hoarse voice, panting.

"Everyone is injured and an ambulance has been called." The security guards who arrived earlier responded.

"Chengcheng ......" Yang Ru's weak voice came through the smoke.

Mu Qingcheng secretly breathed a sigh of relief, at least his uncle was still alive! Cheng Yijie and Yang Ru both fell to the ground, not knowing what their injuries were. She squatted down to inspect, Yang Ru was open and conscious, except for his arm being injured and bleeding, there seemed to be no serious injuries.

Cheng Yijie lay on his side and didn't make a sound, Mu Qingcheng couldn't see where he was injured, and tentatively shouted "Mr. Cheng". He slowly opened his eyes, his face pale, but his expression was calm.

"Where did you get hurt?" Mu Qingcheng asked with concern.

Cheng Yijie's eyes flickered a little strangely, he was silent, and closed his eyes again.

"Help me find it...... USB flash drive ......" Yang Ru spoke with difficulty, he didn't care about his injury, and he was still thinking about the USB flash drive he held in his hand when he came to the stage just now, and he let go of his hand after the explosion, and the USB flash drive disappeared.

Mu Qingcheng understood that the USB flash drive must be very important to his uncle, so he immediately searched around, but did not find the USB flash drive.

Ambulance crews arrived soon and the police came. When Cheng Yijie was carried onto the stretcher, Mu Qingcheng saw clearly that his left buttocks were dripping with blood, and his pants were blown out. It turned out that it was injured in that place, no wonder I was embarrassed to say it. She was sympathetic and grateful, thanks to his heroic act, otherwise her uncle would have died a long time ago. The gesture of rushing to the stage to save people just now is so handsome!

Both Yang Ru and Cheng Yijie were sent to the emergency room, where Yang Ru suffered multiple skin lacerations on his right upper limb and scalp hematoma. Cheng Yijie's buttocks burst. Both of them had other minor injuries on their bodies, and after debridement and anti-inflammatory treatment, they needed to be hospitalized for further observation and treatment, and then placed in the same ward.
