Inside Blustro's residence, Blustro had just returned from Wisdom Shield's castle when he immediately questioned the butler at his side.
"How did the tests on those samples go?"
Blustro had not even waited for the results of Chen Cheng's sample tests before taking the letter of commercial intent to Wisdom Shield. The reason was simple.
First, he trusted Chen Cheng. The Eyeglass Manufacturing Method Chen Cheng had previously sold to his son had earned him a fortune.
Outside Huidun Territory, there were plenty of people with congenital myopia like Melinda, and the method for measuring the degree of nearsightedness existed only in the manufacturing method Chen Cheng had sold them.
Although the technical barrier for grinding lenses was not particularly high, the vision-testing algorithm was unique.
Even when imitators emerged later, the success rate of the eyeglasses they fitted was worlds apart from his family's.
Moreover, those in this world who became nearsighted and could afford to get glasses were all people of wealth and influence, because ordinary people simply did not have the innate conditions to develop myopia.
Helping those wealthy and powerful people solve this minor problem with their eyes had also opened up quite a market for his family.
Of course, Chen Cheng had taught him professional terms such as market expansion and technical barriers, and that was also one of the important reasons Blustro trusted him.
The most important point, however, was that the letter of intent had not truly specified the project of cooperation or its scale. It had merely mentioned a few things in broad terms.
As long as the sample test results were unsatisfactory, he would still have plenty of room to adjust.
Although that might seem somewhat mercenary, Blustro had achieved what he had today precisely by relying on that mercenary nature.
