Being in an ice and snow hell and being hit by an ultra-low temperature blizzard of minus 200 degrees, this is not a good place to greet each other. "Hello. Niss simply said hello to Columbus, and there was no more communication after that.

Talking will cause the two of them to withdraw from the state of breathing as they are, and accelerate the loss of water in the body. Don't look at it just for a moment, in such a harsh environment, it is likely that a small and extremely small gap will determine your fate.

Seeing that Niss and Columbus directly entered the state of cultivation, Lin Su no longer bothered the two. He traveled alone to the place where the beasts were being held, ready to test them for the effects of a toxin-dependent beast.

Three days ago, Lin Su caught these beasts here and fed them the dependent toxin made by Columbus, because it was not a lethal poison, so he had to wait for three days to be able to judge whether they were poisoned through some unusual behavior.

As for whether there is a dependence on this toxin, it will take a month to make a judgment.

Starting with the cheese rabbit with the lowest capture level, Lin Su uncovered its eyelids and looked at it carefully, and some white spots appeared on the iris of the cheese rabbit. These spots do not affect the cheese rabbit's eyesight, but they do indicate that its body has been affected by toxin-dependent.

Checking them in turn, Lin Su saw white spots on the iris of each beast, which was good news.

Of course, being under the influence of toxins does not mean that Columbus was able to control them.

It was only a month later that these beasts had a withdrawal reaction and needed to obtain continuous toxins from Columbus to relieve their suffering, and they could be considered to have officially established a chain of control.

In layman's terms, relying on toxins is like the life and death talisman of Tianshan Tong's control, which is both a poison and an antidote.

This method is much lower than the future Hive Prison Warden Rab using pheromones to control the Jailer Beast, and it will not be absolutely safe, but it can already save a large number of human jailers for the Super Prison.

……

In order to ensure that the experiment proceeded normally, Lin Su had to go every day to find food for the beasts. The meat-eating beasts are the hardest to deal with, but herbivores like the cheese rabbit are the hardest to deal with.

Every time Lin Su cut back a large handful of grass, it would be eaten by the cheese rabbit in less than half a day, and Lin Su had to go again.

After being tortured for about a week, Lin Su removed the cheese rabbit from the experiment list. The Cheese Bunny has a capture level of only 12, and is completely incapable of becoming a Jailer Beast.

Lin Su originally wanted to kill the cheese rabbit to make a cheese hot pot, but in the end, he was worried that there were still toxin-dependent ingredients in its meat, so he had to give up this plan.

Eventually, the cheese rabbit was cut into several pieces and served as a meal for the other experimental beasts.

……

After a month and a half of relentless blizzards, it suddenly stopped without warning. Although the forest is still snowy, the temperature has really increased a lot.

"Mr. Lin, didn't you say that the snowstorm in the frozen season in the Dead Forest would last for three months, could it be that something happened here?" asked Columbus, puzzled.

"We were lucky enough to have a cold day. Lin Su said, "Every few years, the snowstorm that will not stop during the frozen season will be interrupted for a few days, and the temperature will rise sharply, which is the so-called cold day."

At other times of the frozen season, you can only see raging snowstorms in the Dead Forest, and only during the cold days can you enjoy the real snow.

Let's go, I'm not training today, I'll take you deep into the Forest of Dead Silence for a spin. ”

"Even if the blizzard stops, you won't be able to find anything. "Niss doesn't think there will be ingredients that can grow in an ultra-low temperature blizzard of minus 200 degrees.

"Don't underestimate the ability of living beings to adapt to their environment. Lin Su said, "There are some ingredients that only grow in low temperatures, such as the Manna Tree. ”

It is said that the tree of nectar is a tree that can be eaten with both branches and leaves, the sap is luscious, the branches are moist and soft, and the leaves are as beautiful as candy pinchers. Niss recalled.

"I've heard the name of the Tree of Nectar, too. "When I was a child, the old people of the village would always tell us stories about this magical tree, but it seems that no one has ever found the real tree of nectar. ”

Lin Su didn't expect the Tree of Nectar to be so famous, almost to the extent that everyone knew it. He said with some pride: "Congratulations, you will see this magical tree that came out of a fairy tale with your own eyes in a moment." ”

Niss grabbed Lin Su's arm in surprise, "You said that the Tree of Manna grows in the Forest of Dead Silence?"

"That's right. Lin Su nodded, "The reason why the world has never found the Manna Tree is because the growth conditions of the Manna Tree are very special. The tree is very sensitive to heat, so it can only be cultivated in winter and in cold areas below -100 degrees Celsius. ”

Such harsh conditions could not be reached even by the Ice Continent, which is considered to be an extremely cold land. Looking at the entire human world, as long as the frozen season of the Dead Forest can maintain a low temperature below minus 100 degrees for a long time.

"Take us there, I can't wait to see what the Tree of Manna looks like. Niss urged.

Lin Su didn't want to whet everyone's appetite, and walked directly to the location where the Tree of Manna grew.

This tree of nectar was discovered by Lin Su when he came out to look for ingredients a few days ago, and he didn't say it at the time just to surprise Niss and them. Originally, Lin Su planned to wait for both of them to adapt to the severe cold of the frozen season, but he didn't expect that a cold day would inadvertently create a better opportunity.

The Tree of Manna was located in the middle of the Great Needle Hive and the Dragonhorn Swarm, and before they could see the shadow of the Tree of Manna Tree, the instinctive sweetness in the air had already pointed the way for Ness.

Running all the way in search of sweetness, a tall giant tree appeared in front of everyone. The tree is nearly 100 meters tall and the diameter of the trunk at the bottom reaches 30 meters, giving it a very calm feeling.

From a distance, there is nothing special about the Manna Tree, except that the leaves are greener, and everything else looks exactly like a normal giant tree.

"I thought the leaves of the Tree of Nectar were made of all kinds of cakes. Niss said with some disappointment. Her memories of the Tree of Manna come from an illustrated fairy tale book in which the Tree of Manna is overgrown with all kinds of pastries.
