The function of building a biogas digester in Banbu is, in short, to create an environment suitable for the growth of biogas bacteria (including a variety of anaerobic bacteria), accelerate the degradation of plants, remove useless substances, and leave behind the biogas water and digestate rich in various nutrients needed for plant growth.

The most important thing about a biogas digester is to moisturize and seal.

Banbu decided to open up the rock layer inside the mountain on the north side of the cliff, first digging a horizontal passage inward, and after a certain distance, turning vertically downward, digging a deep well at the mouth of the bottle.

The forelimbs are well developed, the tips of the toes are flexible and sharp, and it is easy to cut stones, but the trouble is to carry gravel. The zebra used a bag made of python skin, which was filled with stones and dragged on all fours with its forelimbs, backwards and outwards.

Due to the small size of the wellhead, the exit position is upside down and crawling, which is quite laborious, and the four legs cannot stably climb the stone wall, so the amount that can be transported out at a time is very limited. After digging for a while, you have to transport it out once, up and down, back and forth, non-stop.

The solution was quickly thought of, and hemp rope was made from the skin of a plant called "hemp", and the snakeskin pocket was perforated, and two hemp ropes were tied to the pocket. Every time I drag the hemp rope out of the well, and then drag the hemp rope up, it saves a lot of trouble.

……

The plants are scarce and young, and the demand for nutrients is not large, and Banbu is not in a hurry to build the biogas digester, so he just comes to dig for a while every afternoon, which is considered to be an activity, and by the way, he waits for the return of the patrol soldiers of Iron Knife Peak, collects food, chats a few words, and sends off politely.

The weather was not so wonderful at dusk.

The sky is full of red clouds, and it is a sign that it is going to rain.

Sending away the peach, Banbu lies down at the entrance of the cave to enjoy the food.

After nearly ten days of intermittent work, the digester was nearing completion, and Zebub planned to work overtime tonight to get it out in one fell swoop and then try to see if it was feasible.

"Is the mountain master of Li Zhufeng here?"

It was vague, as if a divine thought was calling.

It's definitely not the spiritual power fluctuations of the Red Cockroach Tribal Warriors!

Madara was startled, and his tentacles stood up and shook slowly, sensing the smell in the air.

Carefully move towards the cliff slope and look down the mountain.

"Is the mountain master of Li Zhufeng here?"

The call of God came again.

Banbu locked on the general direction, and then found the target, a huge insect creature was crawling along the mountain range, slowly moving closer to Li Zhu Peak.

Spider!

Rainbow-like body color, the Rainbow Flame Spider tribe.

It's a traveling businessman!

Ma taro is to follow the traveling merchants of the Phantom Flame Spider tribe around the continent.

Ma Taro explained to Zebrabu in detail about the special tribe of Illusory Flame Spiders: they can only give birth to one life seed in their lifetime, and in order to obtain the Force food they need to grow, they embark on the road of business; They can weave beautiful spider silk bags that extend the shelf life of food, which has become their greatest reliance on walking through various zerg kingdoms and selling goods from one place to another, which is a skill that other races cannot learn. Their life seeds are repeatedly conceived through life sacs, and they have the ability to switch between plant and seed forms at will. They are large and have wide carapaces, allowing them to haul large amounts of cargo......

Various natural advantages have created a special race that specializes in traveling merchants for a living.

Ma Taro dislikes the Phantom Flame Spider tribe very much, and evaluates them as "friendly and honest profiteers on the surface, but in fact they are hypocritical and greedy".

There is no treachery or business, but Banbu can understand.

The Illusory Flame Spider tribe walks between the various Zerg kingdoms on the continent, and their behavior is a proper duty, only trading, not evil, and advocating harmony and wealth.

It's good that it's not an enemy attack.

Madara breathed a sigh of relief, tried to do his best to mobilize his mental power, and replied, "Yes! ”

From a long distance, a stream of spiritual power swept lightly across Banbu's body, and the huge flame spider said:

"Oh, Li Zhufeng really has a new mountain master."

"Hello, young mountain lord. My name is Chonglou. ”

The other party is at least a mountain master-level existence, with a strong soul and strong spiritual power, and can easily transmit information over a long distance with divine thoughts.

Banbu didn't have that ability, so he simply didn't answer, and lay down in front of the hillside, watching the other party's movements.

When he got close to the foot of the mountain, Banbu saw clearly that there was a small flame spider behind the heavy building.

Closer, Banbu found that a small two-headed spider also held several smaller small flame spiders on its abdomen.

The Rainbow Spider tribe has its own kingdom, but the territory is small enough to accommodate the aging tribesmen, so they are out-of-home merchants with their families.

Chonglou stopped at the foot of the mountain and asked, "Young mountain lord, can we go up the mountain?" ”

With some difficulty, Banbu passed his thoughts to the mountain and replied, "Yes." ”

Traveling merchants are still very popular, and they always bring all kinds of strange things from other regions.

Chonglou took the little spider, climbed up the steep hill with some difficulty, and praised as soon as he opened his mouth: "Black carapace, handsome little warrior, favored by the true god of nature, you will become the best warrior in the Cockroach Kingdom!" ”

"Thanks for the compliment."

Banbu replied politely, very uncomfortable. The two sides are severely unequal in size, and Zebrabu must look up.

The body size of the flame spider is naturally much larger than that of a cockroach, and the heavy building is several circles larger than the Lord of Iron Knife Mountain, with a strong belly and a strong back, and a body covered with colorful fluff, which is very beautiful.

Looking up, you can only see the two poisonous limbs of Chonglou glowing with colored halos, and Zebra flapped his wings and took off, hovering low in the air, looking curiously.

The back of the heavy building is not only crawling with large and small flame spiders, but also tied with a large number of colorful spider silk bags, the whole is like a cargo truck. These silk bags contain their trading capital.

When they got to the place, the other spiders, the smallest of which were ordinary plants, all lay honestly on the backs of the heavy buildings, and the larger warriors crawled to the ground and stood in a neat row.

Chonglou began to introduce in turn, pointing to the flame spider that was close to 1,000 and said, "This is Luoshi, a high-level warrior!" ”

Pointing to the other 5 flame spiders of different sizes, he continued: "This is the ground elm, this is the fine-leaved fescue...... This is Xiao Xuemai, and he is still a junior fighter. ”

Chonglou is a mountain master level existence, Luo Shi is a high-level warrior, 4 small flame spiders are intermediate warriors, and the youngest one is a junior warrior. Even the smallest one has nearly 100 or so spreads, which is more than Madarabu.

Other ordinary illusory flame spiders, if you look closely, some of them are about 30 feet full, and they also carry smaller larval spiders on their backs, the smallest ones are only about 10 feet, and the small ones are pitiful.

It is really a big family, from big to small, with clear layers.

Banbu said, "My name is Banbu. Li Zhufeng's previous mountain lord fell unexpectedly, and now I will take over the management. ”

Chonglou was a little sad and said, "When I came, the Lord of Faber Mountain informed me of this unfortunate news. I have been friends with the Lord of Jinzhu Mountain for many years, and I am really saddened by its tragic death. ”

Sure enough, hypocrisy.

Banbu said lightly, "I'm sad too. ”

Chonglou changed his words and said: "All the way north, we saw a large number of plants that died due to drought, and I heard that it was a drought last year. The disaster in Li Zhufeng seems to be more serious, and large areas of the bamboo forest have died. ”

Banbu replied, "As you can see, most of the bamboo forests in Li Zhufeng have died. ”

Chonglou asked, "Banbu Mountain Lord, do you plan to continue the path of the Golden Bamboo Mountain Lord and continue to operate bamboo seeds?" ”

Madara said: "I have this plan at the moment, and I will make specific plans after becoming a high-level warrior." ”

"The terrain of the Jinping Mountains is complex, and we encountered no less than 10 evil beasts on the way here, so bamboo is a wise choice." Chonglou turned around slightly, looked at Banbu's life plant, and commented: "A Xun grass, this surprised me." Yingri fruit, white jade mulberry, and oriental cypress trees are all decent choices. Li Zhu is your best choice. The Iron Knife Tree is a very good species. ”

Zebra was indifferent.

Chonglou continued, "I also felt the breath of the God-given seed, which was on the south side of the mountain. Lord Banbu Mountain, you're an eighth-year-old junior warrior, right? ”

Banbu replied, "That's right. ”

Chonglou asked, "Lord Banbu Mountain, can you let me see your god-given seed?" ”

Banbu didn't think much of it and said, "Of course." ”
