Half a year later.

In a pool of water in the Flame Secret Realm, there was a sudden noise on the surface of the water, and in the waves that parted to both sides, a man slowly stood up.

This man's upper body is ****, and his skin is showing a red color, as if he is oozing blood. His eyes were also red, and even his eyeballs were red. The whole person was fiery red, looking like a blood-colored statue. It's Shabai.

At the bottom of this pool, there is a small magma outlet, and small streams of magma continue to flow out all year round, and the magma contains pure fire spiritual power, which continues to spread into the pool. Over the years, the bottom of this waterhole has become the most vigorous place in the secret realm.

After exploring the secret realm for many days, Sha Bai accidentally discovered a lava flow at the bottom of the waterhole. Linghu Tianjian speculated that in the depths of the magma flow at the bottom of Tandi, there should be a place of Xuanhuo. Xuanhuo is the origin of fire aura, which is why it nourishes this place so vigorously.

For half a year, Sha Bai had been cultivating here the clumsy fire that the Fox Heavenly Sword had imparted.

The full name of Humble Fire Determination is Humble Fire Vajra Ding, which is the secret method of the ancient sect Fire Spirit Gate, and it is an extremely large cultivation system of the Yuan Shen. It contains various methods such as concentrating the spirit, transforming the spirit, calming the soul, gathering breath, and attacking. Linghu Tianjian once taught Sha Bai's breathing method, which was a small part of the clumsy fire determination system.

This clumsy fire vajra was set to work, and the speed at which it absorbed spiritual power was much greater than that of Sha Bai's previous cultivation of the Soul Transformation Determination. Coupled with the abundant spiritual power of the fire at the bottom of the pool, in just half a year, Sha Bai has broken through the realm of intermediate spirit disciples.

After entering the intermediate spirit disciple realm, every time Sha Bai dived into the bottom of this lava pool, he could retreat and cultivate for seven days without leaving the pool. The need for food has also become very small, and it has entered a natural state of valley reclamation. Every time he went out of the pool, he just found some wild fruits in the woods to eat, and he didn't feel hungry.

The aura refined by Sha Bai is all pure fire aura, and every time he cultivates at Tan Di, the abundant spiritual power in his body will spread from the aura nucleus at the dantian to the surface of his skin, making his entire skin turn fiery red, and this red will slowly fade after the cultivation is completed.

The sand white came out of the pool water, the blood red on the body gradually faded, and the skin color slowly returned to normal.

He came to a cyan boulder by the pond, raised his hands, and swiped his fingers in the void in front of him, "poof, puff" several times in a row, and a little red light shot out from the tips of his fingers, shooting on the bluestone opposite. There was a loud bang immediately on the bluestone, and a burst of gravel smoke and dust came up, and the sound was half loud.

Sha Bai approached Qingshi and looked at it, and nodded with satisfaction. Qingshi was hit by the aura shot from his fingertips out more than ten small pits, each of which was the size of a fist.

This method of shooting out spiritual power from the fingertips to release an attack is the "finger sword" method in the clumsy fire vajra determination. When Sha Bai first began to practice the finger sword, he could only leave shallow marks on the bluestone, and later he could slowly hit the shallow grooves. After half a year of cultivation, the spiritual power shot from his fingertips was already able to hit a small pit the size of a fist on the surface of the hard bluestone, and the power was really amazing.

After trying his sword, Sha Bai walked up the hill behind the waterhole to a hut behind the slope. The hut was built in his spare time. In addition to a wooden bed, there are several simple wooden tables and chairs.

On a wooden table in the hut was a swarthy stick-like thing. Sha Bai picked up the stick and looked at it.

This stick was found in a forest called the Iron Bamboo Forest in the secret realm. The soul-nourishing iron wood needed for the Linghu Heavenly Sword is made of this iron bamboo. To make zuò soul nourishing wood, you must first engrave runes on the iron bamboo, and then refine the iron bamboo with the power of the Xuanhuo at the bottom of the waterhole.

Sha Bai placed the soul nourishing wood in front of him, sat cross-legged, stretched out the index finger of his right hand into a finger sword, and began to carve runes on the ironwood. In the past few months, he has tried to carve it several times, but not once. Iron bamboo is said to be wood, but it is harder than iron. If the spiritual power is insufficient, it will not be shaken at all. A few times before, he released his spiritual power to engrave on the surface of this ironwood, but there was no reaction on the surface of the ironwood, leaving no traces.

This time, after cultivating underwater again for seven days, I felt that the spiritual power in my body had improved again, so I decided to try again.

Sha Bai poured all his spiritual power into his index finger and began to use spiritual power to carve on the surface of ironwood. As the spiritual power released by the index finger moved back and forth on the surface of the iron bamboo, this time, the surface of the iron wood finally appeared shallow and concave.

Sha Bai was overjoyed: "I can finally engrave a mark!"

I can engrave the mark, although there is still a distance from being able to engrave the rune, but at least I have seen a ray of light.

More than a month later.

In a clearing in the secret realm, Sha Bai was possessing and inspecting a huge mountain rock, the surface of the mountain stone was black and swarthy, exuding a faint metallic luster, looking like a piece of black iron, which was extremely hard at first glance. At this moment, on the surface of the boulder, there were more than a dozen small holes the thickness of a thumb out of thin air. It was the power of Shabai's finger sword that pierced through it.

"The finger sword has finally been cultivated to the fullest!" Sha Bai let out a long sigh, he closed his palms again, and a few sparks of the finger sword instantly converged in the palm of his hand and called a big fireball, Sha Bai threw the fireball forward, and the fireball shot out, blasting a deep pit of several zhang on the ground one hundred and ten meters away.

Linghu Tianjian's figure suddenly appeared, and said in a deep voice: "Okay, the finger sword has been completed! Let's start carving runes on the iron wood immediately!"

Half a month later, by the lava pool, Sha Bai held a piece of iron bamboo in his hand and looked at the pool.

Linghu Tianjian next to him said: "The rune has been engraved! The next step is to go to the bottom of the pond to draw out the Xuanhuo from the ground, and refine this iron bamboo! This refining needs to be seven consecutive days, and it cannot be interrupted, once it is interrupted, it will be wasted, and you have to start again." To draw out the Xuanhuo and refine the Iron Bamboo, you need to run the two formations of the Heavenly Radiance Array and the Heavenly Light Fire Refining Array successively, you have to reserve the spiritual power in your body to the fullest state, are you ready?"

Sha Bai nodded solemnly: "Ready! Let's start." With that, he jumped into the pool.

At the lava exit at the bottom of the water tank, Sha Bai inserted several jade talismans prepared in advance around the exit.

According to what Linghu Tianjian said, under the lava outlet rich in fire spiritual power here, there is a source of Xuanhuo, and that Xuanhuo is the source of fire spiritual power in the secret realm here. In order to draw the Xuanhuo from this lava outlet, you need to arrange a Celestial Radiance Array near the exit, and then inject spiritual power into the formation, and the Xuanhuo will slowly rise to the lava outlet. Then arrange a Tianguang Fire Refining Array, and refine the iron bamboo with the runes engraved in the Xuanhuo for seven days before it can be refined into a soul-nourishing wood.

Sha Bai inserted the jade talisman, arranged the Leaving the Sky Radiance Array, and then sat cross-legged at the bottom of Tan, chanting words in his mouth, and began to inject spiritual power into the jade talisman in the array.

After more than half a day, as the Celestial Radiance Array moved, a trace of yellow light began to slowly emerge from the magma outlet.
