As Li Ji told him more and more, the expression on Wu Tao's face began to gradually become solemn.

This area is far larger than he had imagined before.

The giant city I saw before was called Tongguan City, but it is only one of the seventy-two giant cities of the human race, and it belongs to the human race forces.

There are as many as one billion people living around Tongguan City alone.

Moreover, in this area, there are not only human race, but also hundreds of species such as the Flame, Blood, Ghost, Cloud, Ice, Snake, Spirit, War, Witch, Rat, Cowhead, Doghead, Golden, etc., which are no less powerful races than the human race.

Due to the special living environment of the underground world, monks and mortals have to focus all their strength on the city to survive.

...

Although the living environment here is a little worse, there is no shortage of resources required for cultivating immortals, and on the contrary, it is extremely rich.

The city lord of Tongguan City is a great monk in the late Nascent Soul stage, with his name and surname Xie.

Under the city lord, there are four deputy city lords, all of whom are cultivators in the middle stage of the Nascent Soul Stage. In addition to the chief and deputy city lords, there are more than a dozen other Supreme Elders in the Nascent Soul Stage.

The survival in the center of Tongguan City is naturally much better than the situation outside Tongguan City where it may be attacked by foreign races at any time.

When talking about this, Li Ji's face was filled with envy.

...

After listening to Li Ji's story, Wu Tao's heart was overturned, but he was silent on his face.

After pondering for a while, Wu Tao asked again, "Li Ji, Tongguan City, do foreign monks have frequent activities all year round?"

"Yes, senior."

Li Ji nodded quickly.

Wu Tao then asked, "Do you know why?"

"this……"

Li Ji hesitated for a moment and replied awkwardly: "Senior, forgive me, I really don't know."

This answer was not unexpected. Wu Tao shook his head. It seemed that he would still have to go to Tongguan City to investigate.

...

Now, since many foreign monks are coming, the possibility of his identity being exposed is very small, so why not go and see it.

Just at this moment, a shocking explosion sounded.

Li Ji suddenly exclaimed, walked out of the stone hall quickly, and muttered to himself while walking, why is it so fast today? It shouldn't be based on time.

Wu Tao also frowned, walked out of the stone palace, and looked into the sky.

A huge peak of hundreds of feet high up into the clouds stood quietly in the middle of these villages, and a trace of black smoke kept coming out from the top of the mountain, as if it was about to explode.

"Active volcano! There is actually an active volcano nearby... "

Are these monks crazy? They actually built the village here."

"Is there a large array here to control it?"

Boom!!

Another earth-shaking explosion sounded, countless black smoke rose, and the entire volcano seemed to come alive and roared violently at the sky.

A huge wave of black smoke columns rushed directly into the sky, dyeing the sky dark.

"No, why didn't the magma flow out?"

It was not until this time that Wu Tao suddenly realized and thought to himself: "This should be the work of the monks in Tongguan City, right?"

At this time, the mortals in the village were kneeling on the ground and shouting loudly that the gifts of the immortal masters have come, thanking the great immortal masters.

Hurry!

In the sky, it was drizzling, and countless black dust fell continuously with the breeze.

Black raindrops kept falling on the ground, dyeing the ground gray-black.

Many children ran to the stone hall, knelt in front of Wu Tao and Li Ji, and kowtowed respectfully, saying together: "Thank you, Master Immortal, for the gifts you gave us..."

"Is this volcanic ash?"

Seeing this, Wu Tao

He stretched out his right hand curiously, and with the spiritual power inside it, some black dust swept in, held it in his hand, and observed it carefully.

"It seems that some artificial ingredients are also brought with me. The monks in this place are so amazing, tsk, it's really amazing!"

"The ash is rich in nutrients and is very beneficial to the growth of plants. In addition, the cultivators have added some other things to it."

...

"With these things, the crops in the land here can produce amazing yields every season.

"The senior said it is right. The adults in Tongguan City controlled the eruptions of dozens of active volcanoes of different sizes nearby, and evenly transported the volcanic ash produced each time to various villages to fertilize the land.

Li Ji, who came to his senses, bent down again and explained to Wu Tao.

"What a terrible power!"

Wu Tao murmured to himself that the formation and cultivation required to control such a large active volcano must be extremely amazing.

...

Moreover, directly controlling an active volcano as a fertilization tool, Wu Tao really admires this design and courage.

However, if the monks in the Jiuzhou Immortal Cultivation Realm really want to do it, they can do it.

However, the monks in the Jiuzhou Immortal Cultivation World will not do their best to think about ordinary people. No monk, including Wu Tao, will keep the good or bad of the daily life of mortals in mind.

...

Because, although the mundane world is the backbone of the immortal world, if it is unstable, the immortal world will also be affected.

However, when the human race dominates Jiuzhou and is invincible in the east, west, south, north and west, cultivators in the Jiuzhou Immortal Cultivation Realm only need sheep management.

...

"That's right, I actually forgot that in this area, the human race is not the only overlord, there are other powerful races that can compete with the human race."

"If you say so, mortals are also a good resource for the monks here."

"There should be some monks in this area who will be responsible for dealing with the climate of natural disasters, and even have harvest monks who are dedicated to farming and increasing land yields."

"I'm afraid these monks have worked hard to do this to increase the number of mortals."

...

Wu Tao sighed. It seems that the monks in this area do not attach much importance to mortals.

It is because of the special environment that they have to find ways to preserve the number of mortals.

The only difference between this and the monks in the Jiuzhou Immortal Cultivation World and regarding mortals as ants is that they are different in various conditions and the specific implementation methods.

Just like sheep grazing, the monks in the Jiuzhou Immortal Cultivation World adopt a rough breeding method because the environment in the Jiuzhou continent is suitable and there is no danger. Mortals can grow smoothly and don’t need to worry about anything.

...

The monks in this area have a harsh environment and many dangers around them, so they have to think of some ways to protect the safety of these mortals.

Although they are in different environments and methods, the final purpose of these two is the same, both to obtain the resources they need from mortals!

...

"Muramasa!"

Just at this moment, a sound that seemed rough and atmospheric, came in from outside the door, although it obviously lowered the sound.

"What are you doing when you are still outside? Why don't you bring it in now!"

Li Ji shouted after hearing the sound, then stepped forward and bowed and said, "Senior, I have ordered people to prepare some food. There is nothing good in the small place. I hope you don't mind it."

Wu Tao looked out the door and saw three or four people walking in with several trays.

Seeing this, Wu Tao shook his head and left the place the next second.

Only Li Ji and these three or four people were left behind, with a confused look on their faces.

Tongguan City.

The meaning of the meaning is that the mountains are divided and the rivers are broken. It is as solid as a golden soup. One man should be the pass, and tens of thousands of riders cannot enter.

Others gathered soil on the plain to form mountains, and the group of crazy monks who built Tongguan City directly broke through a mountain range.

Then, relying on the terrain of the mountains, hollowing out the mountain and building it up one layer after another, connecting the mountains and the city.

This is a giant city that has been built over countless years and generations. It is a giant city that can live in a population of 100 million.

"What a big deal!"

Wu Tao couldn't help but praise him secretly.

When the monks who built this giant city made such a big move, they would naturally not be idle.

This can be seen from the mottled city walls.
