The old village chief knelt on one knee on the rocky ground covered with gravel, reached out and grabbed a handful of limestone, the stone in his hand became shattered with a slight pinch of his hand, and the powder flowed down the gap between his fingers and onto the rocky ground.

The head of Bright, whose face was full of wrinkles, said to Surdak: "It hasn't rained here for months, and even the sea buckthorn grass can't survive, these sea buckthorn grasses are the main food of the limestone iguanas, without which they can only migrate elsewhere." ”

Surdak also did not expect that just separated by two mountain ranges, the environment in the depths of Mount Paglos would be so different from the village of Wall, this area has almost reached the point of no grass, limestone iguanas do not need to drink water in their lives, as long as they can find some sea buckthorn grass in the crevices of the stones, the iguanas can live.

They are probably the most thirsty creatures, and their bodily functions have evolved to treat water as poison, and giving them a glass of water can even kill them.

But these sea buckthorn grasses still need a trace of moisture, and without moisture, even these sea buckthorn grasses are difficult to survive.

Leaving the crumble stone forest, all the way to the 'pustule' mountain, along the way three consecutive hunting grounds failed to find the trace of the limestone iguana, the old village chief analyzed that the main reason is that the Paglos Mountains are too dry, resulting in the sea buckthorn grass can not grow, so the limestone iguana is forced to migrate to other places.

However, the villagers who explored the path seemed very calm, and kept walking in the direction of the 'pus' mountain with the lizard hunting group of Vol Village.

After entering the 'Pus' Mountain, Surdak saw that the gray clouds floating on the top of the mountain were not clouds at all, but smoke erupting from the top of the 'Pus' Mountain, but these smoke did not spread, but only shrouded in the crater of the 'Pus' Mountain.

The road had become very soft underfoot, and a thin layer of volcanic ash covered the ground.

Surdak picked up the water bladder, drank all the water inside, made the somewhat chapped lips moister, shook the water bladder, and saw that there was not a drop of water in it, so Surdak re-hung the water bladder on his waist.

Seeing this scene, the old village chief shook his head slightly, untied a water bladder full of water from his belt, handed it to Surdak and said, "Save some water, enter the Paglos Mountain, water is more precious than food......

Surdak didn't pick up the old village chief's water bladder, but said, "Don't worry, I've been prepared for this......"

As he spoke, he took out a 'Water Gathering Technique' magic scroll from his arms and shook it in front of the old village chief, the old village chief was slightly stunned, and then recognized that it was a magic scroll, and then he knew where Surdak's confidence was.

The villagers of Vol Village continued to walk for half a day towards the 'pustu' mountain, and the ash on the ground was almost an inch thick.

If you step on it, your foot will sink deeply, as if you were stepping on fine sand.

Unexpectedly, there were some sea buckthorn grasses growing on the ground covered with volcanic ash, so the villagers caught some limestone iguanas in some stone crevices filled with volcanic ash, and these limestone iguanas left some footprints on the shallow volcanic ash, revealing their whereabouts, so the villagers can definitely find the limestone iguanas as long as they follow the tracks.

The villagers caught limestone iguanas along the way, and before they knew it, they had come to the foot of the 'Pus' Mountain.

From the foot of the mountain, you can see that there are rivers of lava flowing through the mountainside of the 'Pustu' mountainside.

These lava rivers are not what they seem, with dark red magma floating on the surface of the river, but bands of rock, and wisps of green smoke rising from these hot rocks, but the real magma is wrapped in these ribbon rocks, and is slowly flowing downward.

Above the mountainside, smoke billowed everywhere.

Even if you stand at the foot of the mountain, you can smell a very strong pungent smell.

And the volcanic ash here has been able to submerge the knees of ordinary people, and it is difficult to walk an inch further, and the old village chief led the villagers to capture two iron cage limestone iguanas in this area, which has successfully completed the mission goal of this hunt, and the villagers have a faint joy on their faces.

This time I was able to catch the limestone iguana smoothly, mainly because Surdak's 'water gathering' scroll played a huge role, halfway through the villagers carried the water bladder after drinking one after another, every night Surdak will nail the magic scroll to the stone wall, so that the magic scroll runs to gather water droplets, the water element in the air here is quite thin, far less than when in Vol Village, you can form a rain waterfall on the water tank, but the light rain is enough for the normal use of these villagers.

The old village chief planned to return the same way early tomorrow morning.

At night, Surdak sat on a rock, watching the top of Pus-Bag Mountain seem to be burning with fire, and the countless sparks that burst out formed a large amount of smoke.

He reached for a handful of dry ash, an idea forming in his eyes.

The old village chief enjoyed taking a sip of the water in the water bladder, since Surdak had the 'Water Gathering Technique' magic scroll, there was no need to deliberately save this clear water. He held a pipe in his hand, and took two puffs hard, the tobacco in the pipe became red, like the fire on the top of the 'pustule' mountain, he looked at Surdak's side face, and saw a glimmer of joy in his eyes, so he coughed dryly twice, and asked Surdak, "Did you find anything?" ”

Surdak grabbed a handful of volcanic ash, smiled at the old village chief and said, "These are volcanic ash......

"That's right, everybody knows it's volcanic ash." The old village chief muttered.

"I've been thinking about building a large reservoir in the upper reaches of the village so that the water from the springs can be stored so that the village doesn't run out of water during the dry season." Surdak stretched out a finger and gently wiped the ground of the volcanic ash to tidy up a flat land, then used his finger to outline the terrain of the village of Wall, and then drew a line in the upper reaches of the ravine, cutting off the entire upper ravine......

The old village chief looked at Surdak dumbfounded, listening to his initial idea of Vol Village, but he didn't expect that the reservoir in Surdak's mouth was more like a dam intercepted upstream, the old village chief stammered a little, and said to Surdak: "Are you going to build a wall on the upper half of the ravine to cut off the river?" ”

"If you want to build a reservoir, you must re-lay the bottom of the reservoir to ensure that rainwater does not seep into the ground, and the reservoir must only store water in the summer when the rainfall is abundant, and not only can not store water in normal times, but also appropriately increase the amount of water discharge......

Surdak explained his thoughts to the old chief, and then said to the old chief: "When we build the cistern, we need this volcanic ash, as long as we mix this volcanic ash with some lime powder, we can form a kind of cement, and the floor of the cistern made of cement will not seep water......

The old village chief asked blankly, "Cement?" ……”
