At this moment, Zhang Tie had just come out of the water, wet all over, looking a little wolf, but he was in good spirits. In the first round of the battle against the tenth-level strong warrior on Demon Snake Island named Dawson, he won, humiliated the guy, and escaped from under the nose of the guy, so of course he had reason to be happy. This is not a battle skill, but a victory of spirit and will.

Dawson didn't say that he was level ten, but judging from the way he avoided the crossbow arrows and the way he showed when he was far away, it was almost the same as the miscellaneous pieces of the Zhen family that chased him in the Dragon Cave on the island, and Zhang Tie could judge his level from this point.

Demon Snake Island really sent a tenth-level master to ask for his own life as he expected, which made Zhang Tie feel pressure, and at the same time, a wildfire in his heart was also completely burned, this Dawson was the first stepping stone on his way to becoming a strong man.

"Have those seeds of sea buckthorn started to catalyze?" Zhang Tie asked Heller.

"The first batch of a total of 4oo seeds has begun to catalyze according to different input schemes, and the first result can be known within three weeks at the earliest, if there is an evolved and mutated seabuckthorn tree seed, then you can use the method of increasing the spiritual energy value to make that seed grow quickly, bear fruit, and then obtain a large number of mutated and evolved seabuckthorn tree species!" Heller said calmly, "The aura value and basic energy reserves of the Black Iron Castle can still be supported, but the merit value is now increasing a little slowly every day, and the main source of merit points now is the release arranged by the castle lord on Qianlong Island, which can provide the Black Iron Castle with merit points ranging from 5o to 7o every day." ”

Zhang Tie thought about it for a while, and remembered that because of the generation of the Flower of Life on the Aurora, the merit points he had accumulated were only more than 5oo, and now he had to complete the catalysis of so many sea buckthorn tree seeds at one time, and it was estimated that those merit points had dried up even if they were added to the accumulation of the past few days.

"Wait a few more days, there should be a batch of merits worth in the account!" Zhang Tie said with some uncertainty.

"Possibly?" Heller looked at Zhang Tie suspiciously, very uninterested in this kind of uncertain thing.

Zhang Tie scratched his head, "This is the agreement I made with others last year. If nothing else, there may be a batch of released earthworms in a few days! ”

Heller was relieved......

If Hannah's family will keep the agreement they made with them before they left Brape, then it is probably in the recent period that Hannah's family will begin to collect and release earthworms in and around the village of Chevri, and after a year of recuperation, the number of earthworms that were intended for fodder has returned to its previous level. It should be ready to be released.

But he has been away from Brape for so long, and he was forced to leave in the name of a wanted criminal, and he has not been in touch for such a long time, whether Hannah's family will still fulfill the previous agreement with him, Zhang Tie is not sure about this.

Although he is not in Brape now. However, the ability to control those yeasts given to him by the fruit of creation still makes Hannah's home-brewed beer no longer have the same texture and taste as when Hannah won the Brape beer queen.

Zhang Tie didn't know how the life of the Hannah family was now after winning the crown of the beer queen, how much had changed compared to before, if the Hannah family did not fulfill the agreement with him, he could completely make the Hannah family the same as before as revenge, but Zhang Tie did not want to take this last step. At the beginning, Hannah's family treated him well, and Hannah also brought him a lot of happiness, if Hannah's family really didn't fulfill the plan agreed between them, then forget it, everyone is just destined for this, Zhang Tie doesn't want to see a woman who is good with him end up with nothing.

The merit value can be seen as an opportunity to find another way, Zhang Tie doesn't believe in such a big ice and snow wasteland, and he doesn't even give himself the opportunity to do good deeds. It's a big deal to go back to the Ewindara Islands, and be a madman and a psycho in the eyes of others, and find a fishing area to release tens of thousands of gold coins.

"Speaking of earthworms, there is just a good news to tell Lord Sù Castle, those earthworms in the Black Iron Castle have completed a collective mutation and evolution, and a new earthworm species has just been born in the Black Iron Castle, just waiting for the Lord of the Castle to name it!" Heller smiled.

Zhang Tie, who heard the news, was stunned for a moment. And then there was the great joy, almost a year, to get those earthworms, bees in the Black Iron Castle. There are also Yuan Energy Aura Yeast, potatoes and corn and other species to complete the re-evolution of the work he completely handed over to Heller, just when he was about to forget about it, he didn't expect that a new species was born in the Black Iron Castle. Although Zhang Tie hadn't figured out what these earthworms could do to him for the time being, the thought of being able to eat the fruit of creation and control a brand new species made Zhang Tie's mood full of sunshine.

Zhang Tie was about to open the control panel of the Black Iron Castle to check, but was stopped by Heller.

Heller pointed to Zhang Tie's clothes, which were still dripping water at this moment, "Lord Castle, it's not too late to change your clothes before you check them!" ”

Zhang Tie smiled, and obeyed Heller's Jianyi, anyway, they have all arrived at the Black Iron Castle, and there is time behind them, what is the hurry at this time.

In the following time, Zhang Tie took a shower in the Black Iron Castle, then changed into clean clothes, and sat down on the chair in the room refreshingly and comfortably, and then opened the biology and community management panel of the Black Iron Castle, and found the information about the new earthworm species that Heller said about in the animal management project under the management of carbon-based organisms and communities.

The three-dimensional holograms of the two earthworms appeared in front of Zhang Tie at once......

Just by looking at the appearance of the two earthworms, you can see the difference between the two earthworms.

The individual colors of ordinary earthworms before the mutation were red and reddish-brown, which is also the color of most earthworms, but the color of the mutated earthworm's body is based on the red and reddish-brown, and its head and tail have two more black rings.

In size, the mutated earthworm is also larger than the non-mutated earthworm.

Below this stereoscopic hologram, there is still a comparison of the chromosomes and DNA differences of the two earthworms, Zhang Tie felt that he couldn't understand these things anyway, so he simply jumped to the end and directly checked the new characteristics of this mutated earthworm.

-- The black-ringed earthworm is a completely new earthworm species that has undergone a mutation and evolution. The earthworm has stronger environmental adaptability than ordinary earthworms, its survival time in light state is 31% higher than that of ordinary earthworms, and its adaptability to the highest and lowest temperatures is increased by plus or minus 4 degrees compared with ordinary earthworms. At the same time, the earthworm is more adaptable to various soils and soil qualities, and has a higher ability to fertilize and improve soil activity.

-- The earthworm's feces contain 2.75 percent nitrogen, 1.96 percent phosphorus, 3.77 percent potassium, 35.4 percent organic matter, 23 kinds of amino acids, rich in earthworm enzymes, and more than 10,000 beneficial microorganisms per gram of vermicompost -- while there are only more than 100 in the aging and barren soil. Its vermisite enzyme can kill a variety of viruses, harmful bacteria and a large number of special substances that inhibit plant growth in the soil.

"Please name this new earthworm, Lord Castle!" I saw that Zhang Tie had finished reading the introduction. Heller said from the sidelines.

"Let's call it Earthworm No. 1!" Zhang Tie thought about it casually, and used a lazy way to name this new earthworm.

Regarding the name that Zhang Tie chose for the earthworm, Heller just nodded, and was not dissatisfied, but judging from Zhang Tie's expression, Heller felt that Zhang Tie probably did not fully understand the meaning of this earthworm.

"Does the castle lord know what these earthworms really do?"

"Isn't it fertilizing the fields and improving the soil?" Zhang Tie asked strangely.

"That's true. But does this role mean anything to the castle lord? ”

"What does it mean for me?" Zhang Tie seemed to think of something all of a sudden.

"Yes, did the castle lord think of it?" Heller said with a smile.

"Could it be...... They can make the land completely uncultivated! Zhang Tie's heart was shocked.

"Yes, in the future, as long as the lord of the castle is willing, as long as there is a place where this kind of earthworm is stored, all the farmland can be sown in turns without ploughing, on a piece of land of 10,000 square meters. There are only 9o million of these earthworms inhabiting the soil, and their cultivation effect on the land can be the fruits of the labor of 4 skilled farmers working diligently for 8 hours a day to cultivate the land, not only that, but the manure grown by these 9o earthworms every year is equivalent to adding 14o tons of high-grade organic fertilizer to the 10,000 square meters of land every year! ”

Although Zhang Tie has never been a farmer and has farmed much land, the education model in the school that emphasizes survival ability when he was in Heiyan City made him very clear about what farming is all about, so to speak. At least long before the Cataclysm, the important agricultural activity of cultivation has been almost inextricably linked to planting and farming, and the most widely spoken saying is probably remembered by everyone - without cultivation, there is no harvest. This shows the place of cultivation in agriculture, which is the most energy- and money-consuming thing in almost all the villages, and now, what does Heller say. As long as there are such earthworms, all farmland and land can be no-tillage.

"Not surprisingly, long before the Cataclysm. Some countries and regions among the human beings to promote the kind of more advanced, closer to nature agricultural model has shown the role of earthworms, many areas have promulgated the "agricultural no-tillage law", is the use of large-scale earthworms in the soil to replace human and mechanical farming, which not only saves a lot of manpower, material and financial resources, but also improves the quality of the soil, but also can continue to purify the toxic and harmful substances in the soil! ”

Then why wasn't this method popularized on a large scale at that time?

"There are many reasons, but in addition to the fact that this method was not known to more people at the time, the most important reason is the obstruction of powerful selfish interests that are entrenched in the traditional agricultural model! At that time, traditional agriculture was a low-level, quick success, cutting off farmland and crops from the natural world, this model could make some people rich, and all those who could get rich from here naturally did not want their financial path to be blocked by a small earthworm! ”

Zhang Tie understands that people's greed, selfishness and arrogance make many people think that they are more powerful than the Creator.

In this way, the No. 1 earthworm is indeed very useful, but the number of these earthworms is still relatively small, and if you want them to wave a huge value, the amount required is considerable, for example, in a place as large as the Black Iron Castle, if you want to make this land a good field forever, according to Heller's calculations, at least 6oo No. 1 earthworms need to be put here.

Fortunately, earthworms reproduce quickly.

After solving the earthworm matter, Zhang Tie came to the bottom of the small tree.

On the small tree, in addition to the second iron-toothed hyena Seven Power Fruit that Zhang Tie had been waiting for for a long time, there was indeed an additional Creation Fruit like a lentil.

- The fruit of creation, which has been ripened, how to use it, and eat it directly after picking it. Note that the fruit should not be taken away from the Black Iron Citadel, as the energy and vitality within the fruit will gradually be lost after twelve hours of picking.

-- The creation of a qiē has immeasurable causes, because you, the first earthworm No. 1 appeared in this world, they came out of your creation, so they belong to you, you are the father and God of the thing that was created, and the fruit of this creation will give you the strongest control over this earthworm species in this world from now on, and this control is based on the law of the material existence of the No. 1 earthworm, and your will and command are the meaning of their existence.

Looking at this fruit of creation, Zhang Tie picked it off with a pious mood, before eating this fruit of creation, Zhang Tie touched the trunk of the little tree, and said to the little tree seriously, "Thank you, I wouldn't be where I am today without you, please believe, I won't let this magical fruit you bear go to waste!" ”

The leaves of the small tree were rustling, as if in response to Zhang Tie.

After Zhang Tie ate the magical fruit, it quickly became a magical instinct in Zhang Tie's consciousness, Zhang Tie didn't even have to count it himself, he just wanted to know, and then he knew about these earthworms - at this moment, in the Black Iron Castle, there were a total of 185919 earthworms.

Earthworms love the Black Iron Citadel, especially the soil near the Pool of Chaos, which is like a sacred place for them.

Breed, breed hard, from now on, your greatest task is to try to increase the number of your new species - this is the first order Zhang Tie gave to those earthworms.

After giving this order, Zhang Tie picked off the Qili Fruit, which looked like a small handicraft like an iron-toothed hyena, sat down under the small tree, and put the Qili Fruit in his mouth......
