As Han Li continued to go deeper into the ground, the temperature in the air around him also rose rapidly, becoming hotter and hotter, but the road also became wider and wider, reaching a height of more than ten zhang at its highest point.

Han Li followed the Essence Flame Firebird in front of him and continued to fly forward, his gaze sweeping over the cave walls on both sides from time to time.

The walls of this tunnel are quite flat, and there are traces of man-made repair in many places.

"Could it be the Fire Refining Elder......" he guessed in his heart.

From this person's name, it can be seen that eighty percent of his cultivation is a fire attribute exercise, and the fire attribute aura here is so strong, it is the best retreat.

It can be seen that the person who lays down the ban on the outside to cover up should also be him.

Less than a stick of incense passed, and the dull rumbling sound became louder and louder, as if countless muffled thunders were rolling.

For some reason at this moment, the Essence Flame Firebird suddenly doubled its speed.

Seeing this, Han Li naturally sped up to keep up.

As a result, he didn't fly far, but he felt that a huge fiery red world appeared in front of him, but it was a huge underground cave, which was thousands of zhang in size.

Above the cave are inverted stalactites that are red in color, and the surface is covered with a layer of flames, which are blazing.

Below was a large lava lake, above which hung a layer of crimson clouds like burning flames.

The magma in the lake tumbled and surged, and from time to time huge bubbles emerged, and then exploded, making a sound like thunder.

Flaming red balls the size of fists emerged from the bubbles and scattered in all directions.

"Fire Spirit!" Han Li's eyes lit up.

The entire underground space was filled with a flame-like red light, and the void seemed to be burning as well, and the temperature had reached an incredibly high level, and with the strength of Han Li Xuan Immortal's physical body, he also felt a parchy of mouth.

Gusts of hot wind blew from the surface of the lake, and his skin was faintly painful.

However, seeing this, the Jingyan Firebird was extremely excited.

The bird now flapped its wings and flew, turning into a silvery-white shadow that hovered throughout the space, from time to time it caught a clump of fire essence, swallowed it, and sometimes even flew directly into the magma below, disappeared in the blink of an eye, and then sprang out from another place, very pleasantly.

Seeing this, Han Li's heart moved.

The abundance of underground fire veins here was far beyond his expectations, so it was no wonder that the Fire Refining Elder wanted to use a ban to cover up this place.

The Flame Firebird absorbs the power of the flames here, and it is believed that it will recover soon.

However, there seems to be a downside......

He took a deep breath, his face calmed down, and waved his sleeves.

Hundreds of red rays of light flew out, but they were a fiery red array flag, which landed above the magma lake, forming a huge magic circle.

As the words in his mouth flowed out, the entire magic circle slowly operated, and each array of flags bloomed with red light, condensing into a huge fiery red magic circle.

The Flame Firebird seemed to understand its master's intentions, and immediately stopped frolicking, and flew to the center of the circle.

In the next moment, the flame power of the entire underground space seemed to be attracted, and all of them converged towards the magic circle, coiling up layer by layer around the Essence Fire Bird, and soon formed a huge fiery red cocoon.

Han Li's figure rose from the ground, and after a flash, he stopped in front of the cave wall somewhere in the underground cave, turned his hand and took out a flaming red giant pen, waved it and engraved it, and soon inscribed countless huge runes, forming a flame-shaped pattern.

Then he swayed and appeared in front of another cave wall, and once again waved his huge pen, carving a pattern of flames.

Soon, eight flame patterns were inscribed under Han Li's hand, enclosing the huge silkworm cocoon in the middle.

Only then did Han Li turn his hand and put away the huge pen, reciting the incantation in his mouth.

Airplanes!

The eight flame patterns all burst into dazzling light, and soon connected to each other, forming a huge circle once again, enveloping the huge cocoon.

The double circle faintly echoes each other.

Bang!

The underground space shook slightly, and more flame power surged, merging into the fiery red cocoon.

At this moment, Han Li could clearly feel that the strength of the Essence Flame Firebird in the silkworm cocoon was slowly improving every moment, and a hint of satisfaction flashed in his eyes.

He then made a round trip around the underground cave to make sure that the two circles were running soundly, and then returned from the original path and returned to the outside.

After looking around for a moment, he flicked his sleeves, and a ray of light flew out, landing near the valley, and soon opened a huge prohibition, covering the entire valley again.

After doing this, he breathed a sigh of relief.

Having solved the problem of the Essence Flame Firebird, Han Li was in a good mood and did not immediately fly back to the top of the mountain, but flew towards the outside of Chixia Peak.

Since the 600,000 miles around this Chixia Peak will be his territory in this Candle Dragon Dao from now on, he naturally has to take a good look and make some preparations.

It took half a day like this, and Han Li walked around the entire territory roughly, and set up some sensing magic circles all over the territory to prevent someone from sneaking in.

In the entire territory, Chixia Peak, as the core, is naturally the place where the spiritual veins gather, and the aura of heaven and earth is the strongest.

However, in addition to this peak, he also found two small spiritual lands that were quite acceptable by the standards of the Northern Cold Immortal Domain, and more than ten good ore veins.

Most of the veins have been mined, and the two small spiritual lands have been opened up into pieces of spiritual fields, but they have not been taken care of for many years and have long been abandoned.

If it was other True Immortal Elders, for this kind of spiritual field vein, they would naturally send some more servants to mine it as a long-term spiritual stone income.

However, Han Li had no interest in this, at least for the time being, and quickly flew back to the top of Chixia Peak.

"Elder Li!" Yun Menggui and the others were standing side by side at the gate of that courtyard at this moment, bowing towards Han Li who was falling.

All parts of the top of the mountain have been cleaned and spotless, and those pavilions and pavilions have a new look.

The bamboo pine and cypress seem to have been washed, the emerald green is dripping, and there is a group of golden swimming fish in the small bridge and river, walking and playing in the emerald green lotus leaves, contrasting with each other.

Han Li nodded with satisfaction, arranged a few rooms on the outskirts of the cave mansion for Yun Menggui and the others to live in, and sent them down to rest.

Han Li looked around the cave mansion, laid down some prohibitions, and then came to the elixir garden.

Since the medicine garden here is located outside, he naturally won't grow elixirs that he really values here, but it will also arouse suspicion if it is placed like this.

Han Li pondered for a moment, then immediately divided the medicine garden into several areas, took out some ordinary elixir seeds and scattered them here.

He has done these things many times, and he has long been familiar with them.

It didn't take long for a brand new medicine garden to emerge.

Han Li flipped his hand and took out a jade pot and waved it gently.

A pale cyan spiritual liquid flew out of it and landed all over the medicine garden.

Then with a wave of his hand, a crisp blue light flew out of his hand, enveloping the entire elixir garden.

Dots of green sprouts emerge from all over the ground, exuding a tender green vitality.

Han Li had a smile on his face, then turned around and walked through the courtyard to the cave mansion at the mountain wall, opening the cave door with a wave of his sleeve robe and entering.

This cave doesn't look special on the outside, but there is indeed a cave inside, and at first glance, there are more than a dozen rooms, alchemy room, and refining room, which saves him a lot of effort.

Compared to the courtyard in front of him, Han Li naturally liked the environment here, and I was afraid that the previous cave master thought the same.

After thinking about it for a while, he began to make some changes to this place, transforming one of the most hidden stone chambers into a small medicine garden, and carving out a stone chamber near the mountain wall, and making countless small holes in the wall, so that the light of the stars and moon could shine into this room in the future, so that the palm of the sky could absorb it.

After arranging everything inside the cave mansion, Han Li walked out of the cave mansion again, intending to place a few more layers of prohibitions on the outermost periphery.

As a result, he was about to cast a spell, but his body suddenly stiffened, turned around, and looked towards the elixir garden next to the courtyard.

I saw that in the medicine garden, most of the spirit grass that had just sprouted had withered, and only a few were still alive.

"What's going on?"

Han Li's face sank, and he walked over quickly, pulling out a withered spirit grass.

I saw that the root system of its seeds was completely withered, and it was pitch black, as if it had been burned by fire.

He pulled out a few other spirit grasses, and the situation was the same, but there were also several types of spirit grasses in the medicine garden that were growing well and were vigorous, without the slightest sign of wilting.

Han Li immediately spread his divine sense, and it didn't take long for him to find the reason that might be causing this situation.

Because the underground fire vein has not been controlled by anyone all year round, its abundant fire spiritual power has gradually penetrated up, and all the soil of the entire Chixia Peak contains a rich fire attribute spiritual power.

Such an environment is very suitable for the growth of fire-attribute spirit grass, but if you want to grow other attribute spirit grass in this medicine garden, you will not be able to survive.

Han Li looked at the few spirit grasses in the medicine garden that were growing well, all of them were fire attributes.

He frowned slightly, there was still this trouble here in Chixia Peak.

No wonder no one cares about this Chixia Peak, when he chose here, Yu Xiansheng and Qi Liang had a strange look on their faces.

Han Li groaned slightly, his brows furrowed quickly.

Although this situation seems a little troublesome at the moment, it is not inexplicable, and there are still many ways to isolate the influence of the underground spiritual veins, as long as you set up some forbidden circles that can have the effect of isolation.

Although in this way, the spirit grass's absorption of the leyline aura would be affected, but he was not too worried, after all, he used the green liquor born in the palm of the sky bottle to mature, and he did not have too many requirements for the leyline aura.

As for this elixir garden next to the courtyard, it is for the purpose of hiding people's eyes and ears anyway, and when the time comes, it will directly change to some fire attribute spirit grass, that is.

As soon as he thought of this, he stopped thinking about it and got busy again.
