Old Esso, who noticed this, became even more surprised and uncertain.
But at this moment, he could only wear handcuffs and continue to walk forward under the escort of others.
When they finally walked out of the basement, walked up the stairs, and arrived at the spacious laboratory, the old Esso finally saw the backs of Gu Nian and Lin Chen appearing not far ahead.
They didn't seem to have any intention of doing anything, they just wanted to leave quickly, as if there was something urgent.
The old Esso breathed a sigh of relief when he saw this.
However, he was still observing his surroundings cautiously.
As he walked, he looked at the various corpses of Esso scattered in the laboratory, as well as the huge mecha that they spent a lot of wealth and energy to build, but was corroded.
He couldn't help but frown, thinking to himself that one day, when he makes a comeback, he will definitely not let those hateful humans go!
Esso 1 to 9 are all his own children.
Other Esso are second, third, or even fourth generation.
They are all his grandchildren and great-grandchildren.
The old Esso temporarily forgot his purpose and was so saddened by the situation that he grieved for his dead descendants.
He was so immersed in the sadness in his heart that he didn't even realize that the escorts who had originally implemented a strict surveillance policy on him had all retreated to a place at least two or three meters away from him, and were moving very slowly.
, as if waiting for something to arrive!
When he finally noticed something, it was already too late.
He only felt that something seemed to appear out of thin air under his feet...
"boom!"
He tripped, was handcuffed, and came into close contact with the ground.
This made his heart skip a beat!
He knew what it was that tripped him up!
It was the invisible skin that Gu Nian took off from his body when he passed by him before!
She actually used the invisible skin bag as a rope, and when he saw the death scene of his descendants, he felt so painful that he ignored the surrounding environment, and tripped him!
At this moment, old Esso didn't realize that tripping him up was just the beginning!
After he tripped, it triggered a series of chain reactions!
After Old Esso tripped, he knocked over a shelf next to him. The shelf fell next to the fallen, huge mecha warrior, and pushed something on it.
Come down.
After seeing the thing clearly, a special operations team member quickly shouted: "Everyone, be careful and get out of the way!"
The thing fell from the fallen mecha and landed on the ground next to Old Esso with a bang. It was suddenly broken into pieces. The oily yellow liquid inside, accompanied by a yellow mist, flowed instantly.
And out!
That was exactly the bottle of aqua regia that Gu Nian used to deal with that huge mecha before!
"ah!"
Old Esso couldn't help but cry out in pain.
The broken glass with the highly corrosive aqua regia attached to it attacked Old Esso one after another, making him feel extremely painful.
But his bad times are far from over!
Those viscous, highly corrosive liquids quickly gathered towards him and soon submerged his feet...
