As Prince Xiao approaches the dining hall door and opens it slightly the door to only peek and see that only his father the emperor is waiting for them to arrive, seeing that he is the second one to come he takes his seat on the right side of his father.
His usual seat is next to the current empress but whenever he arrives before her he sits where he sat before the incident with his mother and the current crown prince sits on the left side of their father right in front of Xiao. The empress doesn't sit next to the emperor since all of the citizens of Lotus know that she isn't the emperor's true love the servants make sure the crown prince or Prince Xiao always sits close to their father and mother on their side.
As he takes his seat he is still unaware of the danger he's in because the current empress not being present in the dining hall. While the emperor is trying not to let his worried face show knowing that today is the day Xiao falls into a coma.
While they wait for the 'crown' prince and current empress to arrive, the shadow guards are preparing everything that reveals everything the current empress has done while some others go to Xiao's mother's location and inform her that the plan is going to start as soon as prince xiao falls into a coma.
The food soon arrives and the 'crown' prince right after takes his seat a few moments later the empress arrives and takes her seat. After they are all seated the emperor stands up. "I'm happy that all four of us could finally eat together as a family since I know we all have different schedules and have a hard time eating together let us bless our food for the hard work of our servants and civilians" as soon as he finishes his speech he sits back down and starts eating.
As he starts eating Xiao, Lou and Guohei start eating as well but as soon as Xiao finishes with his first bite he starts to vomit blood and then faints. Prince Lou not knowing that the poison he was given was lethal and since he was right in front of Xiao had a few drops of blood on his terrified face. While the empress had a smirk on her face thinking that the poison was lethal not knowing the poison she put on his food only had the effects she desired and saw happen to one of her disobedient servants vomiting blood then fainting and after a few hours death, but only two of the effect were shown since Prince Xiao became quite resistant to any kind of poison.
Unknowingly the empress who helped him create such resistance didn't know she helped him create resistance to any lethal and non-lethal poisons making him immune to the ones already existing but not completely to new ones causing him to vomit blood and faint in the process.
While in the midst of chaos when the empress was thinking about her future plans "Bring the Imperial doctor immediately and get him to his room!" the emperor yelled knowing this was going to happen but still desperate to get him to his room knowing that Prince Xiao's room was the closest to the imperial doctor.
As soon as they brought Prince Xiao to his room the imperial doctor was there waiting with the materials given to him so he can remove the poison in that instant and only have him be in a coma soon after he was laid in bed the system started to synchronize with Xiao.
