Spy Under Sky Chapter 340

After saying goodbye to Colonel Price, Gavin Lin first went to the Henry Du Watch Store on Nanjing Road, not far from the old drunkard's residence, to buy a Longines women's watch. Then he called a taxi, changed cars several times, and returned to his residence on Lafide Road after making sure that no one was following him.

Arriving at the room on the third floor, Gavin Lin used a special solution to remove the disguise on his face, restoring his original appearance. Then he changed into another set of clothes, walked out of the courtyard, and headed towards the small building of Yao Guanglan, the fourth Concub!ne of Du Yuexiao, which was more than a hundred meters away from him.

When Gavin Lin was a forensic doctor in his previous life, he had done special research on the history of human hair dyeing. Putting aside the history of hair dyeing with natural animal and plant products, the first synthetic non-toxic hair dye in human history was developed by a French chemist named Schueller in 1907.

Two years later, Schueller raised 800 francs and founded the "French Harmless Hair Dye Company" in his apartment on the banks of the Seine. This was also the predecessor of the famous international cosmetics brand L'Oreal.

Under Schueller's promotion, the hair dyes produced by the French Harmless Hair Dye Company became popular in Europe and the United States. In 1920, the company's sales reached 3.6 million francs.
