Chapter 693: Chapter 693: Infiltration Plan Begin!

Under Instructor Mei Lan's guidance, Tang Li Xue and her perfect copy tried to change their 'voice' by modifying their [Telepathy] technique.

It only took them a few minutes to have a grip on it.

When Tang Li Xue and her perfect copy tried to talk to others, their voice became 70% more masculine and heavier.

'Two heads are truly far much better than one... If I am alone, I may need more than fifteen minutes to learn this trick.' Tang Li Xue secretly sighed in amazement.

Then Instructor Mei Lan shoved two other potion bottles onto Tang Li Xue's perfect copy while explaining their functions.

"You can drip this potion to your eyes. It can change the color of your eyes to black. While the other one is a male perfume to cover your body scent." Instructor Mei Lan said while urging Tang Li Xue's perfect copy to use them.

After the perfect copy dripped the potion onto her mesmerizing topaz blue eyes, her eye color changed into obsidian black.
