"Watch out for that yellow glow! that's the Flame!" Grey Shadow reminded from the side.

Sha Bai nodded, looking at the yellow light that was gradually emerging.

To operate the Radiant Formation, it was necessary to continuously inject spiritual power into the Jade Rune Formation, which was extremely draining on him. Fortunately, there is already a lot of fire and spiritual energy here, and Shabai can barely support it while consuming it.

A trace of yellow light continued to converge, getting thicker and thicker.

More than two days have passed, and the continuous yellow light has gathered into a yellow light mass the size of a zhang at the outlet of the magma. The light was extremely dazzling, but strangely, it was called Xuanhuo, but it exuded a sense of coldness.

"Alright! Enough of the Flames, now let's throw Ironwood into the Flames!" said Grey Shadow.

Sha Bai threw a piece of iron bamboo in his hand, and the iron wood fell into the yellow light cluster, and did not fall, but was suspended in it, slowly turning.

"Okay! Start setting up the Skylight Fire Refining Array right away!" Gray Shadow urged.

Sha Bai immediately stood up, and quickly took out the jade talismans that had been arranged before from Tan Di and replaced them with a few new jade talismans.

After changing, Sha Bai immediately sat down cross-legged and began to inject spiritual power into the newly arranged Heavenly Light Fire Refining Array.

With the operation of the Heavenly Light and Fire Refining Array, the yellow light cluster that originally glowed with a cold aura gradually became hot.

Sha Bai only felt that the water around him was getting hotter and hotter, and it slowly seemed to be boiling.

"If you can't withstand the heat, you can separate part of the spiritual power and form a fire spirit armor on the surface of the body to resist. Gray Shadow reminded.

Sha Bai nodded, for the time being, he could still resist. If part of the spiritual power was separated to form the spirit armor, Sha Bai was worried that the spiritual power that would run the Heavenly Light Fire Refining Array would be insufficient.

Seven days passed slowly.

At this time, if someone observes the pool from the outside, they will find that the whole Tan water seems to have become a boiling cauldron, the water surface continues to bubble, the whole pool is boiling, even if it is dozens of meters away from the pool, you can feel a scorching heat rushing to the face.

Under the water tan, Sha Bai sat in place, motionless, and there was a faint layer of red light flashing on the surface of his body. At the juncture of the seventh day, Sha Bai finally couldn't stand the scorching heat of this Tan Di, and separated part of the spiritual power in his body, forming a layer of fire aura battle armor on the surface of his body to resist the heat.

At this time, the spiritual power in his body, not only to operate the Tianguang Fire Refining Array, but also to maintain the Fire Spiritual Qi Battle Armor, was already stretched and barely maintained.

Ling Hu Tianjian stared at Sha Bai intently from the side, with a nervous expression.

The iron bamboo continued to roll in the yellow Xuanhuo light, and the runes engraved on the surface began to become exquisite, emitting pale yellow light, as if alive. At most, with one more pillar of incense, the iron bamboo can be successfully refined. If something goes wrong at this time, it's really a failure.

Another half-pillar of incense has passed. The iron bamboo turned more rapidly in the flames. At this time, the original black iron bamboo has completely turned golden yellow.

The spiritual power in Sha Bai's body was almost exhausted, he trembled slightly, gritted his teeth, and the skin around his body had completely turned completely blood-red, obviously struggling to support himself.

At this moment, there was a loud "boom", and the magma mouth at Tan Di suddenly cracked!

The original magma outlet, which was only the size of a fist, cracked open and formed a much larger opening, and the lava outlet became almost the size of a basin.

At the exit of the crack, a large amount of magma first gushed out, and then suddenly a red-golden ball of light floated out. This light cluster is reddish-gold, bright and dazzling, much brighter than the pale yellow of the Xuanhuo light cluster.

The magma mouth suddenly cracked, which shocked Sha Bai's heart. But he was barely keeping the formation running at this time, and he couldn't move. He tilted his head slightly to the side and glanced at the Linghu Heavenly Sword, his eyes full of inquiry. But he saw Ling Fox Heavenly Sword staring at the red golden light with a shocked expression.

After the red-golden light cluster overflowed from the lava outlet, it jumped up and down a few times on the bottom of the tan, and suddenly floated to Sha Bai's side, and after a few circles, it exhaled and sank into Sha Bai's body.

Sha Bai was so frightened that he almost immediately stood up.

Linghu Tianjian shouted in a deep voice: "Sit still and don't move! boy! Just run clumsily and absorb the aura, your chance has come!"

Sha Bai was shocked and suspicious. After the red-golden light cluster entered his body, it directly poured into the spiritual energy core at the dantian in his body, and then it was silent.

At this time, the spiritual power in his body was like a pool that opened the water inlet and outlet at the same time, consuming and replenishing at the same time. However, the speed at which he operated the clumsy fire determination to absorb spiritual power was far less than the speed at which the spiritual power consumed by maintaining the Heavenly Light Fire Refining Array and the Fire Spiritual Qi Battle Armor, so it was gradually depleted.

After the red-golden light cluster entered the spiritual energy core at the dantian, a wave of extremely abundant spiritual power suddenly gushed out from the spiritual core, instantly replenishing his depleted spiritual energy!

Before Sha Bai could understand what was going on, he was shocked and suspicious, and raised his eyes to look at Linghu Heavenly Sword.

Linghu Tianjian looked at Sha Bai's worried and confused expression, and said with a smile, "Don't worry! That's the Flame Light Banner from the Earth! The ancient fire spirit treasure! It will take the initiative to absorb the fire spirit energy between heaven and earth into your body! It will actually recognize you as the master! You kid really has **** luck!"

Half an hour later, Sha Bai and Ling Fox Heavenly Sword jumped out of the pool. Ling Hu Tianjian held the iron bamboo that had completely turned golden in his hand, and his face was happy.

Sha Bai came out of the pool and immediately sat cross-legged on the ground, observing the spirit core in his body. After some observation, Sha Bai was taken aback, and on the surface of the dantian aura core in his body, there seemed to be a faint flash of a small flag, which was golden yellow, and there were several delicate red flames embroidered on it, flashing brightly and darkly, like a living thing.

After the small flag had already entered the spiritual core in the dantian, Sha Bai obviously felt that he didn't need to run any spirit transformation technique, and the fire aura would automatically slowly converge into the small flag on the spiritual core in the dantian. The little flag was like a huge black hole of spiritual energy, and no matter how much spiritual energy from the outside world poured into it, the little flag would not react. Only the three delicate flames on the flag kept flickering brightly and darkly.

Sha Bai stood up, both happy and a little puzzled, and asked. "Senior Linghu, what exactly is this Flame Light Flag off the ground? How much fire aura does the flag absorb to be full? Why does it seem to be constantly absorbing fire aura and not seeing it full?"

"How many of the seven flames on that flag are lit up now?" asked Linghu Tianjian rhetorically.

"Three. ”

"That's not far from that. If you think about it, the Flame Light Banner from the ground has been here for endless years, absorbing an unknown amount of fire aura, and the flames have only lit up three. If you want seven flowers to be fully bright, do you think about how much aura you need?"

Shabai stuck out his tongue. The fire aura here is so abundant, after tens of thousands of years of absorption, it seems that the reserves of this small flag are only less than half, and it is really a huge amount of aura storage!

"Can I call on the aura in this little flag at any time?" Sha Bai asked again.

"This is natural, as long as your spiritual power is insufficient, the Flame Light Banner will replenish your spiritual energy at any time, and you can replenish it as you go. With your current realm, with this flame flag, it is almost equivalent to having an inexhaustible source of fire spiritual power. However, you are only an intermediate spirit disciple realm, and the amount of aura energy that you can invoke each time will not exceed the range of your realm. ”
