Introduction of Indigo Blue
Indigo blue is a vat dye with a history of more than 3,000 years. Xun Kuang's famous saying of the Warring States Period, "Blue, comes from blue and is better than blue" originated from the indigo dyeing technology at that time. "Qing" here refers to cyan, and "blue" refers to the blue grass from which indigo is made. Before the Qin and Han Dynasties, the application of indigo was quite common.

It has poor light resistance and heat resistance, and is unstable to citric acid, tartaric acid and alkali. 1g is soluble in about 100ml of water at 25°C. Its solubility in water is lower than other synthetic edible pigments. A 0.05% aqueous solution is blue.

In a distant realm where magic thrives, ferocious beasts shake mountains and rivers with their mighty roars, and individuals wield superhuman strength capable of reshaping their surroundings. It is a magical world where the strong rules. But rampant corruption and chaos exist, where slavery, rape, murder, and discrimination against the weak were all but common. The magically superior people trample over the lesser unfortunate folks, using them as stepping stones and disposable assets. All hope for these downtrodden souls seems lost, but the wheels of fate have other plans for them. In a faraway ocean, one that is filled with demons and sea monsters, a great technological civilization suddenly appeared, one that came from a world that is only filled with chaos and destruction. This civilization became the heaven for people seeking a stable and peaceful life. The Earth rose and seas parted ways, and the environment had totally changed for its adaptability. Unfortunately, the inhabitants of this great technological civilization are all but manaless, arriving in a world where they are seen as inferior and as slaves. How will they react of finding themselves in a world where people can split mountains or bend the fabric of space, and where beings exist that even conventional weapons cannot defeat? How will they survive against deadly monsters, magical beasts, and superhumans that could threaten entire nations? And how will the other powers that exist in this world react to a powerful, advanced nation filled with a race they deem inferior? This is the story of one of the most powerful empires on Earth, and how it broke the balance of power and rose to the top.
