Xu Feng has been in the human society for two or three months, so this breakthrough can be regarded as a natural step into the innate peak realm. Not only did the overall combat power double, but he also comprehended the stunt 'Sword Intent Domain', referred to as 'Sword Domain', and his confidence in refining the talisman pen for Lingshuang suddenly doubled.

Xu Feng excitedly ran out of the cultivation space, ready to go to the vice dean, and asked him how the preparation materials were being made, but before he left the Jade Spirit Pagoda, he received a message in his mind, which was given to him by Lian Chen using his soul transmission, so that he could go to see him immediately, and the time was yesterday.

The soul transmission is sometimes automatically blocked by the soul, such as cultivation or emergency, the soul will automatically turn on the shielding function, so as not to disturb, just like Xu Feng in cultivation.

Xu Feng rushed out of the Jade Spirit Tower, spread his wings, and flew out, and asked Lian Chen in his heart, what is the situation? Fortunately, he was not in an emergency, and responded quickly, but did not say the specific situation, just asked him to go to the Drunken Immortal Tower to find him as soon as possible.

Xu Feng shook his head, secretly scolded this bastard for pretending to be mysterious, and asked him if he was in a hurry, he said it was okay, and asked him to wait for a few hours.

Xu Feng found the vice president in the office and asked him how the materials for refining the talisman were prepared?

Xu Feng nodded, and used the Sumeru space to install the refining materials and some beast bones found by the vice dean, pondering the high-temperature spiritual fire that the essence of earth fire is needed to refine this talisman pen.

This earth fire spirit vein, according to the vice president, was guided from the back mountain of Yunmeng through the formation, and it could only be entered with the authorization of the vice president.

Time didn't wait for anyone, Xu Feng jumped on the shoulders of the vice president, and came to the side of a stone door in the alchemy building of the Dao Department, and the vice president pinched the seal and shot out a blue light, which spread to the stone door, and the gap between the stone door and the wall flashed with blue light, and then, a strange pattern array appeared, and the stone door automatically opened, revealing a downward stone step passage.

Xu Feng looked down, there was some dim yellow and red inside, there were no fluorescent stones and other lighting stones on the rock walls on both sides of the stone step passage, the light came from the passage below, he was keenly aware that there was a wind blowing at the mouth of this passage, it was not hot wind, and it was a little cool, it was really strange, but he didn't ask in detail, just urged the old immortal to go quickly.

The vice president had no choice but to shake his head, take him, step into the stone steps, and walk down, and the stone door behind him suddenly closed automatically, the sound was very slight, but there was still some noise, he instinctively looked back, but saw a deep darkness, feeling that they were coming from endless darkness, there was a bit of a depressing illusion.

Soon, they walked through nearly two hundred stone steps, and came to the bottom, there was a winding stone wall passage, on both sides were piled up of stones, there should have been someone built underground, there were still some patterns on the wall, but there were many traces of time on it, and there were some withered yellow moss, and above the wall, there were some lampholders.

On these lampholders, instead of fluorescent stones, the spars resembling fire diamonds resemble a transparent bottle, and only half of the spars are fiery red, like liquid, but with a faint red glow. Each two meters has a spar lamp base on each side of the rock wall.

Xu Feng was very curious, so he condensed his gaze, and now these spars were covered with dense lines, because the vice president was here, he was embarrassed to take down these spars and take a closer look, but as he went deeper into the passage, he saw that the lines on these spars turned out to be a kind of formation, thinking of this way, he felt the surrounding breath, and couldn't help but be surprised: "Old immortal, the dense patterns on these spars are fire gathering array patterns?"

The vice dean nodded slightly: "The Academy Palace consumes too many spars every year for the cultivation of scholars. Natural spirit stones are limited, and one piece is less than one piece, so the department thought of this method to gather the fire qi coming out of the fire spirit veins in the place, collect the fire spirit qi, and let these spars sprint the fire spirit qi and let it be recycled!"

No wonder the fire aura in this passage is very thin, and it is all collected by these spars, Xu Feng nodded secretly, is this school palace still very smart? I know that eating the old book will be eaten up sooner or later, and the only way to do it is to show or find another substitute is the long-term plan of the society, so it seems that the Purple Spirit Kingdom will really be a little interesting!

Without further ado, they quickly walked out of the passage, Xu Feng felt a fire aura rushing towards his face, and couldn't help but sniff, a little intoxicated, it turned out to be a pure fire aura, there was not too much fire poison, it was really weird, when he opened his eyes, he saw that they seemed to be on a cliff, a semi-circular boulder was inserted on the rock, and there was a railing at the front end.

Xu Feng glanced out, and now this is a big cave, he hurriedly rushed to the railing, and now the left and right sides are almost more than two hundred meters of span, up and down There are many traces of artificial excavation, looking down, a cloud of fire and mist is swirling, filling the entire cave seven or eight meters below.

Xu Feng saw that these fire mist were actually fire aura, which had been atomized, and he couldn't see the situation under the fire mist, so he said to the vice president in shock: "The earth fire spirit vein is under this fire mist?"

The vice dean nodded, and with a wave of his hand, a cyan storm swept into the fire mist, sweeping all the fire mist into the storm, revealing the situation below.

Xu Feng looked down and was very shocked, the ground of the cave was not a magma or other earthfire molten river, it was actually a giant fire snake.

This giant fire snake is more than 100 meters long, and the scale venom of the fiery red snake on it can be seen, larger than the basin, lying on the ground, extending to the upper part, and the head of the fire snake, not far from the bottom of this cliff, curled up on the ground, and breathing together, as if asleep, every breath seems to breathe out of the rolling mist fire aura, floating out.

However, the giant fiery serpent was not asleep, but was locked down.

On the snake body of this giant fire snake, Xu Feng looked left and right, there were at least hundreds of thigh-thick chains, binding its snake body, and one end of the chain was rooted in the rock wall of the cave.

Xu Feng pointed at the fire snake in shock: "This is the Earth Fire Spirit?"

The vice dean nodded, and pointed to the wall at the end of the upstream, Xu Feng looked there, and there was a vertical carved array, flashing with the light of the circular array, and inside the circular array, there was a fiery red liquid like magma flowing.

"This is the space array? forcibly detain the Earth Fire Spirit and seal it here!"

Seeing the vice dean nodding, Xu Feng was a little puzzled: "How can this earth fire spirit be a fire snake?"
