For the gratitude of Linlin and the three of them, Gan Guyu was naturally ashamed. Because if it is investigated, Gangu rain can also be regarded as an inducement for Yamashita Yujiu's yin hand. If it weren't for the advent of sweet potatoes and improved grapes, Yamashita Yuhisa might not have been willing to take such a big risk and do things under the nose of the high priest.

Of course, the people of the Natural Forest don't think so. In their eyes, Gangu Yu had become a hero who could solve the disease of cold and evil, and even Elder Si Yao's eyes softened a lot when he looked at him.

When Linlin and the three walked out of the tree house hand in hand, all the women who were waiting anxiously outside the house cheered, and they all rushed up to surround the three of them in the middle, and asked for warmth. Gangu Yu didn't step forward with everyone, but his heart was full of joy, because on the universal creature console, the happiness index increased again, and he soared all the way to 25.

However, after the initial excitement, everyone still did not forget to follow Ganguyu's instructions, and brought bowls of vinegar to various tree hollows and fumigated. But at the same time, there was also the news that Linlin and the three of them had recovered.

When the magicians of the Natural Forest received this exciting news, they were all shocked for a while, and what they brought to Gangu Rain was a precious happiness index. He was about to laugh silly when he just returned to the bamboo house alone, because the happiness index continued to increase, and finally settled on such a fantastic number as 317.

For magicians, it is rare to encounter the cold evil disease once, but once it does, it is a big deal. Like the plague on Earth, it once frightened everyone, and few people survived. But now that such a "malignant disease" has a way to deal with it, the happiness it brings to everyone is naturally unparalleled.

And Gangu Yu, who solved this problem for them, was also rewarded. First of all, when the happiness index exceeded 100, the universal creature console once again gave a monetary reward, but this time it was no longer 10,000, but a huge sum of 100,000!

At the same time, because the happiness index meets the requirements, the portable warehouse and the seed and seedling cultivator have also been upgraded to level 2. The improvement of the warehouse is very intuitive, the length, width and height of the space have been doubled, and the capacity of the entire warehouse has instantly increased to a terrifying level of eight thousand cubic meters, which I am afraid will be enough for a long time in the future.

After the upgrade of the seed and seedling cultivator, it really made Ganguyu study for a while. He first explored the seed and seedling incubator, and the message conveyed to him had become: seed and seedling incubator, level 2, can cultivate seeds and seedlings of intermediate and lower grades, and can choose the optimization scheme of intermediate and lower grades.

Ganguyu took some wheat seeds for experiments, and finally figured out the specific rules of the so-called intermediate optimization. Intermediate seed seedlings are the products obtained after the primary seeds and seedlings are further cultivated by using the intermediate optimization scheme.

Previously, there were only two primary optimization options in seed and seedling incubators: pest and disease immunity and a small increase in vitality. Today, there are five intermediate optimization schemes in one go: drought resistance, waterlogging resistance, high temperature resistance, frost resistance, and pH resistance. Although it is all about strengthening patience, it is really practical for the barren salty continent, which can reduce the burden of the soil cultivated by Gangu rain at a small level, and is more conducive to the promotion of crops at a large scale.

However, it is not so easy to cultivate intermediate seeds and seedlings. Only when two primary optimization schemes were selected at the same time for the primary seed seedlings could the intermediate optimization scheme be selected for cultivation.

Fortunately, the mana consumed by a single intermediate optimization scheme is not exaggerated, and for the same seed and seedling, it is definitely not necessary to choose drought and waterlogging resistance, or high temperature resistance and frost resistance at the same time, but to choose the optimization direction according to the actual situation of the soil. Crops grown in bitter cold areas will be selected for frost tolerance when optimized, and crops grown on saline-alkali land will definitely focus on drought tolerance and pH tolerance optimization when cultivating. In this way, the consumption of cultivating intermediate seeds and seedlings is completely acceptable.

Because of the solution to the disease of cold evil, Gangu Yu can be regarded as having a lot of benefits this time, but this matter is not yet a satisfactory solution. He was lying on the bed with Erlang's legs crossed, humming a little song back and forth, but his mind was spinning rapidly. I don't know how long it took, but a knock on the door outside the bamboo house brought his thoughts back.

Gan Guyu opened the door and looked, and without waiting for anyone to speak, he smiled slightly: "Let's go." ”

Not far from the natural forest, there is a post station, where Yuhisa Yamashita and his party are stationed.

After the reception banquet last night, Yuhisa Yamashita led his deputy back to the post station quietly, and after making sure that no one was monitoring and eavesdropping, he laughed wildly.

At the reception banquet, everyone's attention was mainly on Yuhisa Yamashita, and no one noticed the movements of his deputy. Under the vague signal of Yuhisa Yamashita, his deputy successfully completed the plot against Xiaoyu.

It is a medicine that can infect the human body with cold evil, and in earthly parlance, it is a dose of the wind-cold cold virus. This virus is naturally colorless and odorless, and it is difficult to detect, and it is not afraid of harming itself if it is beaten out with special methods. Yuhisa Yamashita has been getting this killer feature for many years, and he has always been carried by his deputy, but he has never been reluctant to use it.

But this time, the natural forest is an unheard of sweet potato, and a sweet and sour grape, all of which make Yamashita Yuhisa determined to get it. For a long time, there has been some controversy in the Wizard Academy about letting him serve as the procurement of the Natural Forest, but fortunately, he has a good background and is good at drilling, so he barely stabilized his position.

But he knew that he urgently needed some results to gag some people's mouths. Sweet potatoes and improved grapes are one such opportunity.

Naturally, he could also expect that the sweet potatoes and modified grapes would definitely not be cheap. Therefore, even if this cold evil poison is really precious, it is definitely cost-effective to activate it at this time! Yamashita Yujiu told himself this more than once, and he really gave such an order to his deputy.

His deputy is also a thoughtful person, and deliberately chose Xiaoyu, who was performing in the field. First, Xiaoyu's strength is not outstanding, and the success rate of being infected with cold evil is even higher. Second, because of Xiaoyu's location, it is most convenient for him to start, and it is the least easy for people to see any clues, and because the distance is enough, it is difficult to infect himself.

Yuhisa Yamashita's plan was successfully completed, and he forced himself to suppress his inner ecstasy and returned to the station, waiting for Gangu Yu and the high priest to exchange sweet potatoes and modified grapes for the antidote to the cold evil.

He had already begun to fantasize about how his position in the Wizard's Academy would be strengthened and even improved when he received the new breed that the Natural Forest had "painstakingly cultivated" at a very low cost, and then returned triumphantly.
