Astral Cockroach

The sludge pools in the swamp are rich in marsh gas bacteria needed for plant decomposition. Collecting sludge is essentially collecting bacterial cultures.

Banbu used a 50cm diameter Mázhú bamboo section, opened at one end, and with great effort, filled it with sludge. Because it was too large and heavy, Lizhu helped transport it.

One trip is enough.

Transport it back to the mountain, pour it into the biogas digester, draw water from the mountain's reservoir, irrigate appropriately, and collect some clay from the foot of the mountain as a culture medium for the bacteria.

Next, Banbu spent an entire day carrying a snakeskin bag and cutting grass on the mountain.

On Lizhu Peak, the bamboo forest that had withered due to the drought last year had various bamboo trees flowering and seeding with their last nutrients before dying, to continue their lineage. These seeds, after hibernating through autumn and winter, sprouted and grew in the spring.

At the same time, all sorts of weeds spread their seeds through various means, also taking root, sprouting, and growing wildly.

Since Banbu planned to plant bamboo on a large scale, cutting out weeds was a necessary task to ensure the smooth growth of the bamboo seedlings.

The biogas digester could utilize the weeds, which was killing two birds with one stone.

The grass stalks were all cut close to the ground. The sickle-like sharp toe tips gently hooked together, easily cutting them off at the roots, then chopped into small sections and stuffed into the snakeskin bag.

He carried bag after bag up the mountain, emptying them into the biogas digester, filling about half the pool, and then sealing the wellhead with a stone slab.

Banbu spent several more days cutting all the weeds in the newly grown bamboo forest on the mountain, collecting the grass leaves and piling them up on the flat ground of the cliff for future use.

If the organic fertilizer obtained from the biogas digester's fermentation has a significant effect on promoting plant growth, then withered branches and fallen leaves will definitely be used in large quantities in the future.

…

The three original stones were indeed a great help to Banbu's growth, alleviating the current shortage of Origin Power intake, and allowing him to enter the molting and evolution state nearly 10 days faster than expected.

As an L9 Primary Warrior, with a body length exceeding 60cm, his feeding ability greatly increased. For example, animals like wild rabbits, he needed two a day to be full.

Different from ordinary creatures, cockroach warriors have a large storage capacity for nutrients and energy. Once full, they are not hungry for a day. In the future, when he becomes a High-Level Warrior, after a full meal, if he doesn't eat Origin Power food, he can probably go without food for half a month.

…

The first batch of organic fertilizer from the biogas digester was freshly produced.

Not very ideal. After the plants rotted and decomposed, a large amount of protein, especially the gas produced by the sulfur element, was foul-smelling and unpleasant.

However, it was still much better than picking up animal manure or something.

Banbu first experimented with ordinary bamboo seedlings that looked relatively fragile, taking biogas liquid for irrigation and biogas mud to fill the ground.

After 5 days of continuous comparative observation, he first confirmed that it would not harm the plants, and secondly confirmed that it had a certain growth-promoting effect, but not as significant as he had imagined.

The four High-Level Warriors on duty at Iron Saber Peak to take care of Banbu, Lizhu was the closest to Banbu and also the most interested in the biogas digester that Banbu was tinkering with. These days, he had been observing the growth of the experimental bamboo poles.

"Banbu, the effect is not as good as you said!"

Banbu thought slightly and analyzed, "The soil of Lizhu Peak is already the most fertile humus black soil. The objects we are experimenting with are already growing well, so we can't see the effect."

Lizhu was, after all, a High-Level Warrior, and had rich farming experience. His brain was flexible, and he understood immediately, agreeing, "That's right, we should choose relatively barren soil for the experiment."

After Lizhu finished speaking, he added, "The growth of Life Seed requires much more nutrients than ordinary plants. Fertile land is easily depleted, Zhi Zhi, that, Banbu, why don't you try it with your Life Seed?"

Banbu's thoughts moved, he tapped his antennae, and said, "Lizhu, I have a way, I can immediately test whether the biogas digester fertilizer is effective."

Biogas water is definitely not as stinky as animal urine, and biogas mud is definitely not as stinky as animal manure. It's just that cockroaches have a keen sense of smell, so they find it so unbearably stinky.

Banbu endured the stench, carried a bamboo tube of biogas liquid, and approached the God-Given Seed. Anyway, he had already confirmed that it was harmless to plants, so he could try it boldly.

The God-Given Seed felt Banbu's ill intentions and released intense thoughts of anger.

Banbu ignored it and directly irrigated a ramet below a plant with the biogas liquid.

The God-Given Seed's intense thoughts of anger suddenly calmed down. It was stunned for a while, and then conveyed an indifferent and mocking thought to Banbu: Want to harm me? Sorry, this thing is beneficial and harmless to me, the more the better.

Plants have no sense of smell and cannot feel that kind of stench. Their roots can very well distinguish whether biogas water is harmful or useful.

Banbu affirmed to Lizhu: "It's really effective, it's effective!"

Lizhu asked, "Banbu, can the God-Given Seed distinguish it?"

Banbu said, "Yes, this is its instinct, it won't be wrong."

The God-Given Seed's violent temper, thankfully it's a plant. If it were an animal, feeling "ill intentions," it would definitely jump up and fight to the death. Pouring a bamboo tube of biogas water down can smooth out its irritable and angry emotions. Banbu was very certain that biogas water helped its growth.

Lizhu said, "It's dark, and it smells bad. It doesn't look very good, and it smells even worse."

Banbu said, "It's much better than picking up animal manure."

"Yes, that's right." Lizhu chuckled, "Everyone suspects that Putao's Life Seed is growing so well because he secretly picked up dung, haha."

Banbu was speechless.

Everyone knows that animal manure is the best fertilizer, but that's too disgusting. As a Blatta Tribe warrior, how could he do such a degrading thing.

Lizhu stepped forward, his front claws and toe tips digging open the topsoil of a ramet, looked at it, and said, "Banbu, the God-Given Seed's demand for fertility is even higher than ordinary Life Seeds. Look carefully, the soil's fertility has decreased."

Feeling the ramet's soil being dug, and the roots being exposed, the God-Given Seed anxiously conveyed thoughts of help to Banbu.

Banbu ignored it, stepped forward and looked at it, and said, "That's good, I'll irrigate all its ramets once."

After speaking, he carried the bamboo tube and flew to the north side of the mountain, and went into the cave where the biogas digester was built.

One end of the bamboo tube was opened, a hole was drilled, and it was tied with hemp rope. It was thrown into the pool, filled halfway, lifted up, carried, and flew back to the south side of the mountain.

Currently, the total number of God-Given Seed ramets is as high as 24. Banbu patiently made 12 round trips, irrigating each one with a small half-tube.

Every time Banbu made a round trip, the God-Given Seed conveyed a happy thought: it expressed satisfaction and gratification with Banbu's diligent labor, and encouraged Banbu to continue his efforts.

Banbu hadn't paid attention to the God-Given Seed's strange thoughts at first. After finishing his work, just as he was about to explain the principle of biogas digester production to Lizhu, the God-Given Seed sent a thought of urging and annoyance.

Turning his head to check, the ramets that had been irrigated earliest had already absorbed the biogas water nutrients.

Terrifying absorption ability!

"It's gone."

Banbu sent a thought to the God-Given Seed.

The God-Given Seed still sent back thoughts of urging and anger, containing a very clear meaning of blaming.

Banbu suddenly woke up and understood a problem: the brain-dead tree spirit of the God-Given Seed seemed to have reversed the master-servant relationship! Did it regard itself as a servant and coolie?

"With my size, how should I dig a biogas digester? What location on Iron Saber Peak do you think is more suitable?" Lizhu saw Banbu suddenly stunned, and softly called out, "Banbu?"

"Oh." Banbu said distressedly, "This brain-dead idiot is inherently arrogant and conceited. It seems that reasoning is not feasible!"

"Ah?" Lizhu was confused and didn't know what he meant, and called out again, "Banbu? What are you talking about?"

"It's nothing, I suddenly realized a very serious problem." Banbu shook his head and said, "It's not really a problem, don't worry, Lizhu, come, I'll continue to explain the secrets of digging a biogas digester to you."
