The lake was surrounded by trees, blocking Su Bai's view.
He turned to Yan Jiao and the others and said calmly,"Take me around the lake.”
"Alright." Flame Horn nodded and led the way.
Su Bai observed while he came to the high slope by the lake, which was a small cliff, seven or eight meters above the lake.
He stood at the edge of the cliff and looked down, muttering in a low voice,""If I can build a few buckets to carry water from here, I don't think I need to go to the lake to fetch water.”
"Yeah, why didn't I think of that?" Flame Horn's eyes lit up when he heard this. He felt that this method was very good.
Blacktooth revealed his sharp teeth and said,""I'll get someone to get more vines later.”
"No, the efficiency is still too low. It will only reduce some danger, but it won't solve the problem of the totem warriors moving water back and forth.”Su Bai shook his head and rejected the idea.
"Ah?" Flame Horn, Blacktooth, and the others were dumbfounded. Why couldn't it work?
"Let's continue walking." Su Bai did not explain much.
"Alright then." Flame Horn had no choice but to lead the way, but in his heart, he had decided to let the Totem Warriors fetch water from the cliff in the future.
The group of five arrived at a low-lying area filled with wild grass.
"Eh? This place is not bad." Su Bai's eyes brightened. He looked around and found that the low-lying area was the lowest place around the lake.
He thought of the dry stream and said softly,""If the stream opens up from here, then the water level of this small lake will definitely drop by more than half.”
"What do you mean?" Yan Jiao, Yan Hua, and the others didn't understand.
"It's okay if you don't understand. You'll understand later.”
Su Bai pointed at the weeds in the low-lying area and ordered: "Pull out the grass here. Be careful of snakes.”
"Alright." They replied in unison.
Flame Horn and Blacktooth entered the low-lying area. The experienced Totem Warriors would first explore the bushes to scare away the wild beasts that might be hiding inside.
Su Bai stood aside and watched the four of them pulling the weeds. He glanced at the cow-horned girl who was bent over. Her perky butt was covered by the animal skin skirt. He had the urge to slap her.
He quickly restrained his emotions and scanned his surroundings, measuring the distance between the low-lying area and the lakeside.
"Less than ten meters. Dig a ditch there. With the help of the totem warriors, it shouldn't take long.”Su Bai glanced at Flame Horn and the others. They were totem warriors indeed. The grass was visibly shrinking.
"Roar…"
A beast's roar came from the distant forest.
Su Bai heard the roar and was stunned. He frowned: "You can't dig ditches."
A beast's roar reminded him that if he dug a ditch, it would immediately be occupied by other beasts and the water would be polluted by the beasts.
"The water pollution is the biggest problem now. There are more than ten fierce beasts in the small lake. I don't want to be covered in parasites.”
Su Bai knocked on his head and whispered to himself,"" It's a little impractical to filter the water source…"
"Wu, all the grass has been plucked." Flame Horn called out softly.
"Oh." Su Bai came back to his senses and looked at the muddy low-lying area. After pulling out the weeds, the low-lying area was even lower than he had imagined.
He came to a low-lying place and stepped on the muddy mud. He squatted down and dug the mud. He rubbed it hard and realized that there was really a lot of water.
"Someone, dig down from here until you see sand.”Su Bai said with a smile.
He had already thought of a solution to the unrealistic idea of filtering water. Wasn't soil the best filter?
"I'll do it." Blacktooth immediately responded, his ten fingers bent as he quickly dug up the soil.
Su Bai was speechless as he looked at Blacktooth who was digging the soil like a dog. The scene was too novel. The soil was thrown several meters high and they had no choice but to retreat.
"Wu, why are you digging a hole here?”Flame Horn asked curiously.
"Haven't you guys dug a well before?" Su Bai asked in surprise.
"What is a well?" Yan Hua asked in a clear voice.
" Uh…" Su Bai was speechless and explained helplessly: "It's just digging a hole from the ground to get the underground water.”
"There's water in a hole?" Yan Jiao and Yan Hua said in shock.
"Not every place has water.”Su Bai sighed.
For example, it was very difficult to dig wells in mountainous areas. After all, the geological structure was different. Su Bai had asked Blacktooth to dig the hole because there was a lake nearby and water could seep in from underground.
"Then can we dig a well in the tribe to get water?”Flame Horn asked expectantly.
"I can't." Su Bai shook his head heartlessly. The location of the tribe was not good. There were few trees around, which showed how much water there was underground.
"..." Yan Jiao, Yan Hua, and the other totem warrior's expectant eyes immediately dimmed.
"By the way, do you know of plants with holes in the middle?”Su Bai asked expectantly.
He didn't know if there was bamboo in the primitive society. If there wasn't, he would temporarily give up on transporting water to the tribe. They could only send all the totem warriors to escort the people of the tribe to transport water. They could transport enough water for a few days at a time.
"Yes, there are quite a few." Yan Hua said in a clear voice.
"Several?" Su Bai was stunned.
"Yes, there are hollow trees, red knot trees, and Heartless Grass.”Flame Flower said the names of the three plants.
"Are there any of these three plants nearby?" Su Bai asked anxiously. He wanted to see if there were any bamboo-like plants.
"I only see hollow trees nearby. The other two plants can only be found in the ancestral land.”Flame Horn continued.
"Is it a lot? How long was it? Is it easy to cut down?" Su Bai asked three times.
"It seems to be quite a lot. It's as long as more than twenty knots.”
Flame Horn frowned and thought for a while." It's easy to cut. I can break a hollow tree with a few punches."”
"If there are more than twenty knots, it's equivalent to ten meters long.”Su Bai relaxed.
He did not expect to find a plant that could replace bamboo.
