287 Master Sheng Tries the Cream

Later at night, Jian Yiling headed over to the Yu Residence with her ointment cream.

Zhai Yunsheng was to become the first clinical test subject of Jian Yiling's scar removal cream.

Before this, all of Jian Yiling's experimental data had been gathered from animals.

According to the regulations, enough data must be obtained from animals before the cream could be used on humans.

Furthermore, the only reason why Jian Yiling dared to use Zhai Yunsheng as her first clinical test subject was because before she entered this world, the cream had been widely used by her patients. There was enough data that had been collected from humans.

Jian Yiling asked Yu Xi to smear the cream on Zhai Yunsheng's wound.

As Zhai Yunsheng's wound had been relatively new, this was a good time to apply the ointment.

Under Jian Yiling's request, Yu Xi once again donated his 'first' time. This time, it was applying an ointment to another person.
