He Xiaotong and Zhou Ke stayed at Wang Heng's house until Sunday afternoon before leaving, and the two girls slept in another bedroom at night, everyone was an acquaintance, but they didn't have to worry about the only man in the family.

The two girls left, the family was completely quiet, Wang Heng was still on sick leave for the next week, He Xiaotong and Zhou Ke had to go to class, and they would come over on Friday or Saturday, and Wang Heng also had time to explore the small world.

In the past few days, Wang Heng has made a new discovery in the small world, in addition to the dirt and stones, there is only the world tree more than a foot high, Wang Heng's discovery is on the world tree, the leaves of the world tree occasionally appear a milky white liquid, and when it accumulates to almost a drop, it will slide from the leaves into the soil due to gravity.

Even if it was just a drop of water, it would be extraordinary to have a connection with the World Tree, Wang Heng felt that this milky white liquid must be a treasure, and it should be collected.

The World Tree is still very small, and putting a few porcelain dishes under the tree can occupy most of the area, and the milky white liquid will drip onto the porcelain dishes if it slides down from the leaves, so Wang Heng bought more porcelain plates on Taobao.

In the blink of an eye, a new day arrived, and there were a few more drops of milky white liquid in the porcelain dish under the World Tree, only three drops to be exact.

Maybe these three drops are the output of the World Tree for most of the day, and it is also possible that one or two drops fall into the soil, anyway, the yield of this milky liquid World Tree is very small, and Wang Heng will not be able to study it for the time being.

At one o'clock in the afternoon, the six guinea pigs, cages, and rat food purchased online arrived, and the courier brother delivered them directly to the door.

Wang Heng received the courier and moved it to the living room, and then took out the scissors to unpack the boxes one by one, and the six mice were packed in six plastic boxes that were not too large with ventilation holes, and there were a large number of wood chips in the box, which had the effect of protecting the mice.

Looking through the plastic box, you can find that the six mice are depressed, and the mice can only stay in a small space for two days, and they will toss back and forth because of the transfer package.

Wang Heng did not rush to release the six mice, but prepared to assemble the six mouse cages first.

The six squirrel cages are of the same style, with plastic plates on the upper and lower sides, four barbed wire fences in the middle, one of which has a cage door, and the space of a squirrel cage is about six or seven cubic decimeters in size.

With no experience, Wang Heng took a lot of time to assemble the first rat cage, and then the assembly of the five rat cages became faster and faster, and it took nearly half an hour to assemble the six rat cages.

After the rat cage was assembled, Wang Heng walked to the bedroom and kitchen respectively, and found two pairs of gloves, one was the black line gloves that he wore when he went out in winter, and the other was the yellow rubber gloves that he wore when wiping things with a rag and cleaning up.

The main purpose of finding out the gloves is to prevent the mouse from being bitten by the mouse when taking it, although it is unlikely that the captive-bred mouse has bacteria and viruses harmful to the human body, but if it is really bitten by the mouse, Wang Heng will definitely have to go to the hospital for a few injections, so try to avoid the chance of happening.

Wang Heng looked at his left hand and then at his right hand, and finally decided to wear gloves only on his right hand.

First put on a line glove, then put on a rubber glove on the line glove, and put two layers of gloves on the right hand, the defense is there, but the fingers become "stiff", and you can't do the thing of removing the tape on the plastic box, so you can only give it to the left hand who is not wearing gloves to do.

Remove the tape of a plastic box, grab the plastic box with a gloved right hand and send it into a rat cage, operate with one hand, laboriously open the plastic box, and pour the sawdust and mice into the rat cage together.

Along with sawdust and mice, there is also rat droppings!

A foul smell came to his face, Wang Heng was so disgusted that he almost vomited, quickly turned his head to the side, and fanned it with his left hand to fan away the smell.

The mentally ill guinea pig moves into the cage, as if trying to find a way to escape.

Closing the door of the rat cage, Wang Heng continued to put the other five mice into the five rat cages in turn, and after doing this, Wang Heng also added a little water and rat food to each rat cage.

Seeing the figure of food, although the mice still feel uneasy about the unfamiliar environment, under the influence of hunger, the mice walked towards the food, and under the observation of an unknown giant creature, their bodies trembled and ate quickly, holding a rat food about the size of a person's index finger.

When the mice were eating, Wang Heng cleaned up the living room, collected the express packages scattered in the living room and put them in the garbage bag, and after cleaning up the living room, Wang Heng sat on the sofa to rest for a while and surfed the Internet, mainly to give the mice a little time to recuperate.

About an hour later, Wang Heng put down his mobile phone and prepared to start the experiment, the name of the whole experiment was "Xuanhuang Small World Biological Survival Experiment", the main content of the experiment was to determine whether the Xuanhuang Small World could allow humans to survive through mice.

The first step of the experiment is to put a mouse into the small world, this step is very important, if the mouse enters the small world and will die soon, Wang Heng needs to spend more time to find the reason for the death of the mouse, whether it is gravity factors, air factors, or bacteria and viruses and other factors.

The six mice were named after No. 1, 2, 3, 4, 5, and 6, and Wang Heng added more rat food and water to the cage containing the No. 1 mouse, at least to meet the needs of the No. 1 mouse for a week's survival, and carefully lifted the mouse cage, Wang Heng sat back on the sofa.

"Whew"

took a deep breath, and the next moment, the rat cage in his hand appeared on the ground of the small world, and Wang Heng quickly closed his eyes to concentrate, and his consciousness entered the small world.

In the small world of Xuanhuang, Wang Heng carefully observed the mice in the cage in front of him, and watched the mice scurrying around in the cage uneasily because of the sudden change in the environment, with a smile on his face.

The mouse did not die immediately when it entered the small world, which is the best news for Wang Heng, which means that the environment of the small world can meet the survival of creatures for at least a short time, the gravity will not be too large, there is air and oxygen, and the mouse will not die immediately after entering the small world.

Thanks to the contribution made by the mice, every year there are tens of millions of mice on the blue star who dedicate themselves to human science, and it is the life of the mice that makes human science develop rapidly, and now the mice are contributing to Wang Heng's exploration of the small world.

A minute passed, and the guinea pig was still alive.

Five minutes passed, and the mouse was still alive.

Ten minutes passed, and the mice seemed to become more energetic.

Half an hour passed, and Wang Heng determined that the first step of the "Xuanhuang Small World Biological Survival Experiment" had passed successfully, and the next step would be the second step of the experiment, observation and comparison.

Observing the survival of the No. 1 mice living in the small world, and then comparing them with the five mice in the outside world, the second step of the experiment lasted until before He Xiaotong came over this week.

Most girls shouldn't like rats, and a small number of girls will even be afraid of mice, before He Xiaotong comes over, Wang Heng will send all the mice and mouse-related things into the small world.
