After Tai Jia was carried out of the big volcano by the ghost Fangsu, he was looking forward to it outside with the others, looking at the narrow entrance of the cave on the mountainside without blinking, and everyone was sweating in their palms.

"If my brother has three long and two short, I will never ......"

"I'll kill myself to accompany him, okay!" Tai Jia said to plug the threat of Ghost Fangyue back into his mouth.

She stared straight into the dark hole, her nails sinking into the flesh.

When Tai Hao Duo appeared outside the cave unharmed, everyone was relieved, Ghost Fang Yue ran to him crying, Tai Jia rolled her eyes and fainted, she had no guardian spirit, her physique was even weaker than Aragaki Yi, she was roasted enough in the volcano, and she was frightened, at this time, seeing that Tai Hao Duo was fine, the tight string in her heart was loosened, and she also fainted.

Ghost Fang Su poured water into her mouth while pinching people, and finally woke Tai Jia up.

Seeing her wake up, Fang Su threw her to the ground and walked over to greet Taihao Duo, and everyone surrounded him in the middle, asking this and that.

"Brother, you're not hurt, are you?"

"Brother Duo, what happened to the fire spirit, you killed him?"

"The Lava Fire Spirit is no longer an obstacle for us!" he turned his head to look at Tai Jia, "Is she okay?"

He took two steps forward to pull Tai Jia up, and found that her hands were a little cold, but her face was slightly red and hot, if she didn't recuperate well, she would definitely get sick with her physique.

"I'm fine!" she took two deep breaths, feeling refreshed.

Hundreds of people entered the interior of the volcano along the winding and secluded cave, the stone steps are slowly upward, through several forks, the widest place is more than two hundred steps wide, the narrowest place can only pass through two people at most, the others are entering the belly of the volcano for the first time, looking at the cone-shaped stone pillar above, like the jagged fangs in the mouth of a monster, can't help but be amazed, when they reach the inside of the large volcano, they are even more surprised by the vast space inside.

Tai Jia was a little complacent about finding such a fortress-like place that was easy to defend and difficult to attack, and said smugly, "Build a city here, you can attack it, you can defend it, it's a natural castle." ”

"Boss Duo, I'm asking you for an appointment!"

"What appointment?"

"I want everyone to obey my orders when it comes to building a city!"

Ghost Fang Su smiled, "You know how to build a city?"

"This girl knows astronomy, geography, in the middle of the people, strategizing, winning thousands of miles away, before I know the three points of the world, people love, flowers bloom...... Let me tell you this, my level of subject knowledge, all of you in the Great Wilderness Kyushu combined, is not half as good as me!"

Lao Mo grabbed a handful of soft volcanic soil, "The soil here is too loose to build!"

"Who said that it was made of earth, there are not so many stones!"

"Then the matter of building the city will trouble you. ”

Tai Jia named the construction of the city as the 'Ant Nest Project', and called himself the 'Chief Designer of the Ant Nest Project', forming a team of people and having a clear division of labor, the internal space of the large volcano is vast, and the stone platforms protruding from the stone walls are of different sizes, some are flat, some are uneven, she first investigates the most suitable place to build the main city, and then surveys the surface hardness, internal air flow direction, etc.

Taihao Duo, Ghost Fang Su and the others couldn't understand some of her actions sometimes, and they were even more puzzled by some strange words that often popped out of her mouth.

"What is the origin of this woman, it can't be from the barren river, right?"

The Great Wilderness Kyushu is bounded by the barren Ze, the north of the barren Ze is Yanzhou, Suizhou, Yangzhou, Dingzhou and Xuanyan Prefecture, and the south is Baoxiang Prefecture, Dayu Prefecture and Cangdi Prefecture, the two are very different, and even the language is not compatible.

Tai Hao Duo has always been very curious about Tai Jia's life experience, and there are many speculations, looking at the woman standing behind a flat rock, holding her chin and contemplating, he said in a deep voice, "I suspect that Tai Jia is not a person who purifies the dust!"

Ghost Fang Su was about to speak, Tai Jia walked over with the drawings in his hand, "Heh, you two brothers are quite idle here! ”

Taihao Duo smiled, "What's the task?"

"Hollow out this place, cut the stone into a foot long, three feet later!

Ghost Fang Su said angrily, "Who told you to call me that?"

"Didn't Satsuki always call you that, I think it's good, it's very appropriate!"

Ghost Fang coaxed people to go to the back mountain to work as a lumberjack, Taihao Duo used the spear of the broken blade to cut those hard rocks, and the attribute was to break the medium-grade spirit treasure to cut gold and broken jade, plus Taihao Duo's brute force, it was not difficult to cut stones, but the efficiency was too low, and the progress was very slow by him alone.

"Building a city is not something that happens overnight!" Elder Lu said comfortingly when he saw Tai Jia's sad face.

Tai Jia shook his head, "Efficiency, efficiency is too low! And these people don't understand anything, I have to teach everything by hand, hey, even if there are a few local city builders, they are better than these amateurs......"

Taihao Duo said, "We are short of manpower now, and we don't need too big a city for the time being, just enough to live!"

Tai Jia raised his eyes and looked at him, "People have no long-term worries, everything is the most important foundation, especially when building a city, although the interior of the large volcano is vast, but the overall space is limited, we must make the greatest use of the advantages here when laying the foundation, the planning I made is not ten years, a hundred years, but a thousand years, the defense facilities in the residential production area, etc., must be related to each other, this is a system engineering ......"

"As for the population problem you mentioned, as long as the resources are sufficient, the fertility of human beings is very strong, and a few baby boomers come down, this place can be full. ”

Taihao Duo smiled bitterly, "In front of you, sometimes I feel like I'm just an ignorant baby. ”

"But I have a better way to dig holes in the rock walls. ”

"Oh, let's hear it!"

Facing the lava pool below, Taihao Duo summoned the Lava Fire Maiden, and the two were in a state of mind, and the Fire Maiden condensed a molten ray and cut a boulder off the rock wall like a thread-cut potato.

Tai Jia clapped his hands and praised, "Yes, with this metaphysical power, why didn't I expect it...... Well, what about the transportation problem, such a heavy stone, it is too inefficient to transport it by manpower!"

A cloud of ghostly light appeared in Taihao Duo's palm, it was Ruoyao's Void Mansion, which had been refined by Taihao Duo.

The ghostly light engulfs the boulder, then floats to the stone platform above and spits it out!

Bang Bang ...... Applause rang out.

"Boss Duo, please forgive me for underestimating your wisdom. ”

"It's you who underestimate the world!" he said, Tai Jia pretended to be stupid and smiled.

With the help of the mysterious power of the lava fire girl, the speed of city building has been greatly improved, and Tai Jia was still worried that the mud mixed with volcanic ash to bond the stones was not strong enough, but the lava fire girl directly melted the junction of the two boulders into one, and she wanted to dig a reservoir in the upper layer of the mountain wall, just like a big lizard lying on the stone wall of the barren dry dragon clicked, and dug out a big pit on the stone platform.

The red-blooded dragon was lying lazily on the lower stone platform, the cold-blooded animal was very comfortable roasted by the magma pool, and it had a chain of iron ropes tied to its tail, which was originally a high-grade spiritual treasure prepared by Ruo Qiu for the subjugation of the barren dry dragon, which was extremely strong, the best at binding the giant beast, and was used as a cable, and there were huge trees hanging at the other end.

On the stone platform, Tai Jia raised the chess piece in his hand, it curled the snake's tail, and the iron cable pulled the giant wooden lever to raise the stone strips and timber at the other end, Tai Jia attached great importance to the defense of the main city, and made the greatest use of the advantages of the large volcano itself, the main body of the city was on the inside of the hollowed mountain wall, and the outer building was surrounded by stones.

"My requirement is that the city can at least withstand the collision of a giant beast of the level of the Desolate Dry Dragon! We must ensure stability and solidity, otherwise if there is a giant beast in the hands of the enemy, we will not be buried alive inside this volcano! This hollowed-out inner city will be our last fortress. ”

Everyone worked in shifts, day and night, only Taihao Duo and Ghost Fang Su were resting on the back of the drought dragon to lead the lava fire element to quench the tripod body.

In just two months, the buildings on the south side of the inner wall of the large volcano have been quite large-scale, but most of them are stone chambers carved out by brute force by the wild beasts such as the drought dragon and the red-blooded dragon, which looks very rough, and the more exquisite buildings may have to be slowly carved by hand in the future.

During this time, the food they ate was wild beasts hunted from the forests north of the volcano, and the water they drank was the condensation of the tears of the gods.

"Sixty, pour me a glass of water!" Tai Jia said, leaning against the stone chair and holding the drawings.

The strong man Tai Sixty was a slave who was bought together, stupid and rude, but loyal, and after some training by Tai Jia, he had already thrown himself into her five bodies.

Elder Lu walked happily with two potatoes in his hand and said, "Sure enough, it's as the girl expected......

"Call me Chief Designer!"

"Sure enough, as the chief designer expected, those black soil ashes are really fat, I have never seen such a big potato!"

Tai Jia pursed his lips and smiled, "The stone platforms with volcanic ash accumulation inside the volcano can be used to develop greenhouse crops, so that even in winter, you can eat fresh food, and once the big volcano is besieged by the enemy, it can also solve the food problem, but the water condensed by that drop of gem is a bit wasteful, and when I find the underground river here, I will design some windmills to carry water......"

Before the words fell, he suddenly heard the cry of a frog in a rock crevice under the volcano, echoing in the enclosed space of the voice, "It's Xiaoyue, go and see!"

Satsuki and Wakabi took some people to look for underground rivers inside the large volcano, and followed the steam coming out of the rock crevices to find several naturally formed underground tunnels, and sure enough, there was the sound of water flowing in the depths of the tunnels.

This dark river flows through the fissures below the volcano, and for hundreds of millions of years it has washed out an empty underground cavern, the water flow is slow, but the water is alive, and the dark underground cavern has some glowing plants and ores, and the reflection is sparkling on the surface of the water.

Ruo Biao asked people to set up a fire by the water, one can illuminate, and the other can measure the direction of air flow in the cave, so as to judge the trend of the dark river, when Tai Jia said this method, Ruo Biao also had to admire the young but intelligent woman, and was annoyed that he didn't see that she had such a ability before, but for Tai Jia to be a slave for several months, he didn't dare to mention half a sentence now, for fear of provoking revenge.

For the first time, the underground riverbed, which had been dim for thousands of years, lit up with the light of flames, and some fish in the river that had long been accustomed to the darkness felt the light and heat and swam towards the shore.

These fish are very large, the small ones are two or three feet long, the big ones are one foot long, there are no scales on the body, there are no eyes on the head, but there are many slender whiskers on the side of the mouth, which are very flexible.

At this moment, there was a commotion in the depths of the dark underground cave, and a sharp chirp echoed in the cave.

By the light of the fire, I saw strange shadows swaying in the cave, and a strange shadow pounced on top of Ruoqiu's head, and two sharp claws grabbed at his head.

Everyone was shocked, gathered in a circle and hit the strange shadows above their heads with the weapons in their hands, Ruo Xiao used to be the great master of the human-faced wolf after all, although he was robbed of his real name Lingbao Bone Demon Blood Barrier, but it was not trivial to be on the side, he grabbed the big claw, and blood-colored runes appeared on his wrists, crawling along his arms, only to hear a scream, the strange shadow fell to the ground, and trembled in pain.

When everyone looked closely, it turned out to be a black strange bird, two people tall, with black feathers, hard as steel, a strange face, a sharp mouth like an iron hook, a pair of black eyes that were surprisingly large, and two cat-like ears on both sides of the head.

The number of strange birds fluttering overhead was extremely large, and the cry of the one on the ground attracted more strange birds, Ruo Wei protected Ghost Fangyue behind him, and let everyone quickly retreat into the big volcano, Ghost Fangyue picked up the magic toad drum and knocked it on the belly of the big toad.

There was a croaking of toads, and the strange birds fluttered and fell into the dark river, and the rest of them all crashed into the cave like crazy.

I can't believe that the Dragonfly Drum has a miraculous effect on these strange birds!
