What is the reaction phenomenon of starch and iodination turning blue?Iodizing starch to blue was a chemical reaction. From the reaction principle, the starch was a spiral structure formed by the condensation of alpha-glucose molecules. Each glucose unit had a hydrogen group exposed outside the spiral. Iodine molecules interacted with these hydrogen groups and were embedded in the axis of the starch spiral. This effect was called clathration. The product was a clathration. During this process, the properties of the hydrogen group changed, so it was a chemical reaction.
This color reaction was very sensitive and could be used to identify the quantitative and qualitative analysis of starch. It could also be used to analyze the content of iodines. In the textile industry, it could also measure the completeness of cloth desizing. Different types of starch reacted differently with the iodines. Amylose was blue when it met the iodines, while starch was purple-red when it met the iodines. Dexterin was blue-purple, purple, orange and other colors when it met the iodines. Moreover, the clathrate formed by starch and iodines was the most stable at room temperature at a pH4, and the color reaction was most obvious in slightly acidic solutions.

The reason was that workers learned from work and improved their labor proficiency, resulting in a long-term average cost reduction. This was also a typical example of the learning effect.

Witch PhenomenonIn medieval Europe, there was a phenomenon called Witch Fever. At that time, society was in turmoil, and religious and secular powers were intertwined, ruling together.
The Church initially held the main jurisdiction, believing that they were the spokesperson of God and could judge religious crimes and heretical thoughts. As time passed, secular governments also desired the power to judge, and secular courts gradually rose. This power fusion and competition affected the development of the judicial system.
Demonesses were defined as people who made a contract with demons and used dark magic to harm society. They were mostly described as women and were a symbol of evil. This definition was influenced by religious ideas and social prejudices.
In 1484, Pope Innocent VIII issued an encyclical condemning witches, and two priests wrote The Witch's Hammer, which became the " Bible of Witch Trials." In trials, interrogation and torture were common methods. The trial process included preliminary investigation, collecting evidence, listening to witnesses 'testimony, and other links. However, the trial process was not fair and perfect, often causing innocent people to be forced to admit to crimes they did not commit.
Most of those accused of being " witches " were poor, old women and widows without social status. They were mostly innocent victims of the world's grief, and there were many absurd accusations during this period.

In terms of the core gameplay, players had different opinions. Some felt that the levels were too simple, the character's stats were too high, and it was easy to clear them automatically. There was a lack of strategy, while others felt that the combat operations were too cumbersome.
Before the game's public beta, it had experienced many twists and turns. There were changes to the release, and it was also affected by the pace of the Seventh Epic, which resulted in a bombardment of negative reviews on many platforms (at that time, the second beta had just ended, and the reputation was originally quite good).
