The tragic fate of Zougu did not make Lu Cheng sad for long.
Lu Cheng followed Dr. Ji Chuan to learn about some plants in this world that have distinct magical characteristics.
These plants, like the animals in this world, no longer stay in the soil and grow through photosynthesis. They all have some unique survival skills of their own.
These survival skills are all related to magic, such as the gathering spark that automatically launches fireballs, the blinding tree that will go blind as long as the pollen is inhaled, and the brilliant grass that will instantly release strong light when it senses danger.
According to Elder Cassia's description, these plants can all be used as alchemical materials, and most of them are extremely expensive.
Alchemical materials. In the eyes of the people in this world, these plants that contain a lot of magical power are one of the methods to use them to make alchemical potions.
But Lu Cheng believed that if combined with modern technology, these magical plants with... very distinctive characteristics would be able to play a more useful role.
One of the most well-known examples on Earth is artemisinin, extracted from the stems of Artemisia annua.
After Elder Cassia identified the magical plants raised in the ecological park and informed Dr. Ji Chuan of the growth locations, habits, and basic pharmacological effects of these plants, Dr. Ji Chuan took him to the area where Earth plants were cultivated.
"This plant is called potato. We are used to calling it potatoes. It grows best in a cool and humid environment. Its tuber is usable. It contains a lot of starch, followed by protein and crude fiber..."
Dr. Ji Chuan took potatoes, one of the essential crops for opening up new land in another world, and introduced a lot of things to Elder Cassia in bits and pieces.
Elder Cassia only understood the growth habits of this strange plant, but he had no idea what nutrients it contained.
"This plant looks a bit like black potato balls." Elder Cassia took the finished potato from Dr. Ji Chuan. "Black potato balls are also one of the main crops we cultivate."
"Then old man, can you ripen this plant?"
Dr. Ji Chuan pointed to a potato planted in a pot. It had been less than two weeks since it was planted and only a small green seedling had grown.
"Let me try."
Elder Cassia came to the plant pot and his expression became serious. He knew that this was his chance to show himself in front of the gods.
In the morning, the Dark Green Clan had demonstrated how to ripen the plants in this world. Now in the afternoon... they were going to try to see if they could ripen the plants on Earth.
This is also the main purpose of Lucheng digging out this deep green clan.
Dark green inscriptions flashed on the back of Elder Cassia's hand. There were as many as forty inscriptions.
The researchers beside Dr. Ji Chuan were already prepared and took out their cameras to start recording the scene.
Maybe next they will study the principles of using magic to ripen plants.
But after Elder Cassia's magic overflowed, the little green potato seedlings did not change at all, and Elder Cassia himself was stunned for a moment.
Elder Cassia, realizing his shame, increased the output of magic power in his body, and the number of inscriptions increased from more than forty to fifty.
But the green potato sprouts still didn't react at all, and the green light in Elder Cassia's hand seemed to be just for illumination.
"This...is impossible." Elder Cassia's forehead was covered with sweat and his breathing became increasingly disordered.
Mobilizing so much magical power is also a burden on Elder Cassia's body.
"That's enough." Lu Cheng interrupted Elder Cassia's spell.
"Lord Lu...Lu Cheng, there must be some accident." Elder Cassia looked very frightened at this moment.
The reason why the Dark Green Clan was able to take root and survive in Skare and gain status was because of their ability to accelerate the growth of plants.
But this ability fails in front of plants on Earth.
"Potatoes can't accumulate magic power, so no matter how you cast magic on them, it won't have any effect." Lu Cheng said.
This result was also expected by Lu Cheng, because the plants and organisms on Earth do not have cells that can store magic power.
Maybe the magician's fireball attack on the earthlings could have some effect, but the earthlings would probably be completely immune to magic like curses.
The main reason is incompatibility.
"Please let my children try again." Elder Cassia obviously thought that Lu Cheng regarded them as useless.
"Don't try. What kind of food did you bring with you? Did you bring the seeds of the main edible plants of the Far South Empire?"
Lucheng did not expect the magic of the Deep Green Clan to bless the hybrid rice and instantly increase the yield to 8,800 per mu, but it was a fact that they could ripen the plants in this world.
Well, since the Archdruid on Earth can create hybrid rice on Earth, he can also create a high-yield edible plant called 'hybrid rice' in this world.
"Yes, the common edible plant in the Far South Empire is the wheat tree. One tree can produce a large number of edible seeds. We have brought a lot of seeds from this tree." Elder Cassia said quickly, "There are other plant seeds, Lord Lu Cheng... If you allow, we can show you the magic of the plants right away."
"Okay, how much are the plant seeds you brought worth? And please give me a suitable price for the cost of cultivating them." Lu Cheng didn't ask what specific plants they were.
The plant seeds that these dark green clans brought with them when they fled must be closely related to the continuation of the entire race.
"Let me…let's make an offer?"
Elder Cassia once again encountered a trading method that was completely different from that of the Far South Empire. The Far South Empire always set the prices and did the buying and selling, and Elder Cassia didn't even have the ability to refute.
"Yes, the currency circulating in Skarre now has no credit value, but our daily necessities tickets and meal tickets do, so you can quote a price that you think is appropriate. Of course, I can also choose to reject the price you propose." Lu Cheng emphasized a fair trade here, but in fact it was not fair.
The Dark Green Clan now had to rely on the rabbits to survive, so Elder Cassia was a smart man and must have known that as long as they followed the rabbits, they would have meat to eat, so his decision was...
"It is enough for us to ask that you can protect us. We dare not ask for anything more. Besides, you have already given us a reward." Elder Cassia said humbly.
When he was talking to Lu Cheng, he also went to the cafeteria and the "shop" in the ecological park.
There are all kinds of delicious food in the cafeteria and magical alchemical props in the canteen. Elder Cassia must have something he wants.
But the problem is that they are enjoying the warm spring-like environment in the park and their work tasks are easy.
In the past, they had to do all the farming, harvesting, and transporting of food by themselves.
But now all the Deep Green Clan has to do is farming. It's so easy that I don't know what to say. The most important thing is... the salary is paid on a daily basis!
"Then come with me, I will take you to see our farmland." Lu Cheng said.
