The sodium cyanide solution was refined in the workshop, and it was called the sodium cyanide solution. Its liquid color is pure and clear, and its nature is fierce and poisonous. It is dangerous to touch and smell.

At that time, there was an order to strictly control this thing. The craftsman is careful to abide by the regulations, and the utensils are carefully made. Store in a strong kettle and protect it. Every time you use it, you must record the number in detail, and be careful.

One day, the workshop was a new apprentice, ignorant and ignorant. Seeing the sodium cyanide solution placed on the shelf, I didn't know its danger, and looked up rashly. When the master caught a glimpse, he shouted to stop it, and his voice was fierce: "This is a highly toxic thing, and it will endanger your life if you touch it, so you must not act rashly!" The apprentice was terrified, his face was as pale as soil, and he knew the harm from then on.

Another year old, there was a bandit who wanted to rob the sodium cyanide solution to do evil. Everyone in the workshop worked together to defend against the enemy, and with courage and determination, they kept this thing safe, so that it would not fall into the hands of traitors and cause harm to the world.

As the years passed, everyone became more and more proficient in the protection and consumption of sodium cyanide solution. Everyone knows that although this thing is very useful, it is also very dangerous. They must be in awe and always be cautious, so that they can keep safe and secure.
