Song Jian passed through a curtain of light like water waves, and truly entered the underground building that the necromancer had spent hundreds of years building.

At this time, the entire underground building was like an inverted funnel, narrow at the top and huge at the bottom, and along a rotating stone staircase, Song Jian entered the entire underground building area.

At this time, Tang Li on the ground suddenly found that countless bone beasts had turned into ashes, but there were still many bone beasts, under the scorching of that dark red flame, they still retained their last breath and entered a state of near death.

Tang Li excitedly drew two daggers and pounced on the bone beast closest to him;

Burst~

The dagger glowed with silver light, easily piercing the skeleton behemoth's defenses and plunging into the burning green flames in the skull.

This is the undead flame that maintains the existence of the Bone Behemoth, if the Bone Behemoth is intact, with Tang Li's strength, it is impossible to harm this flame at all.

But now, the bone giant beast that had entered a near-death state could no longer maintain its own defenses, and Tang Li didn't waste much effort and directly inserted it.

The undead flame, which had been thought to be very weak, exploded with a "poof" with this blow, turning into countless tiny flames that overflowed from the skull of the bone beast.

The originally high head of the bone beast fell silently, and after the entire body lost the strength to maintain it, it collapsed with a bang and turned into a pile of broken bones.

A pale golden treasure chest, shining in this pile of broken bones, Tang Li found that his experience points had directly increased by 5%.

"Although I killed a seriously injured monster, these monsters are more than twenty levels higher than me, just the experience of leapfrogging is enough for me to upgrade several levels......" Tang Li exclaimed excitedly, he had never encountered such a good thing, there was a place that entered a near-death state, and a monster more than twenty levels higher than him let him kill.

Tang Li didn't bother to pick up the pale golden treasure chest, and directly pounced on the second monster that had entered a near-death state.

……

Song Jian killed hundreds of undead monsters at once, and the experience gained increased the experience slot a lot, although it was not yet at the full level, it was only six to seven percent away from the upgrade.

The funnel-shaped underground complex is connected by a sturdy stone staircase, where huge palaces are built, and the surrounding rock walls are inlaid with oil lamps that emit a pale green glow.

Song Jian even saw that translucent soul shadows were constantly wailing and struggling in the oil lamps, and these oil lamps were burning the souls of living beings.

Song Jian didn't encounter a single monster along the way, which made him relax a little bit, although he didn't know where the necromancer had fled, but this was his lair, as long as he followed the stone stairs all the way, he would definitely be able to trace his traces.

At this time, the necromancer was at the bottom of the huge space, and here was not known how far away from the ground, a huge purple-black flame, like a black sun, hung above the last layer, and the phantom of a phoenix could be faintly seen inside.

It can be seen that this phoenix seems to have fallen into a deep sleep, and the crisp phoenix chirping, like a whisper, is constantly transmitted from the small sun, and the entire flame is breathed in and out with the phoenix's chirping, as if it has its own life.

The necromancer knelt on the ground, and at this time, in front of him, there was a huge pentagram, and from the center of this pentagram, a trace of purple-black light was constantly drawn out and submerged into the small sun overhead.

"Great Tannos, you are my only faith, I am willing to offer everything I have to you, and let you be the only master......"

The necromancer knelt in front of the pentagram and prayed in a low voice, and with his prayers, the purple-black light in the pentagram suddenly became more and more brilliant.

The phoenix in the flames continued to absorb the purple-black light in the pentagram array, and with the necromancer's prayers, the necromancer's muttering began to sound in its ears, and the phoenix, which had fallen into a deep sleep, also became irritable, and its body began to tremble slightly.

Rumble~

I don't know how long it took, the sun above my head suddenly exploded, and a huge purple-black phoenix slowly floated in the air, staring at the necromancer kneeling on the ground, with an angry look in its eyes.

……

Song Jian walked slowly down the stone staircase, and suddenly heard a roar from below, and at the same time, a scorching, corrosive heat wave gushed out from below.

When Song Jian, who was standing on the stone staircase, had not come back to his senses, this sudden heat wave suddenly disappeared, and it was just a scorching temperature remaining in the air, telling him that none of this was an illusion.

"This smell ......" Song Jian frowned, although the corrosive smell in the air was also dissipating rapidly, but Song Jian accidentally inhaled it, and suddenly felt a stimulating burning sensation coming from his respiratory tract.

At the same time, a strong aura came from below, and this aura became stronger and stronger, giving Song Jian the feeling that it was like a giant beast that was waking up from its sleep.

At this moment, Song Jian suddenly saw that the task in the taskbar had been completed inexplicably.

"Is the necromancer dead?" Song Jian had a look of surprise on his face, you know, that necromancer has the strength of a king-level boss, although the undead creatures he summoned were killed by Song Jian with one move, but for a necromancer, how many of these undead creatures he wants, as long as the materials are sufficient, he can make as much as he wants, and there is not much damage to his own strength.

But now, such a powerful necromancer suddenly died, which surprised Song Jian and at the same time, there was also a trace of fear.

After hesitating for a moment, Song Jian turned around and left, running quickly up the stone stairs.

At this time, in the hole that was not known how deep from the ground, a handsome man with purple-black hair, wearing a luxurious purple-black robe, was standing at the bottom with an angry face, and in front of him, there was a pool of charred black shadows, which had seeped into the floor.

"Small smash, you dare to ......" A series of foul words erupted from the mouth of this handsome man, and the surging aura emanating from his body became more and more agitated, and cracks began to appear on the ground and rock walls around him, and the cracks faintly shone with dark red light, as if streams of magma were about to flow out of the cracks.

At this moment, he suddenly looked up, as if he sensed something, and with a soft shout, the man's figure, like a black flame, flew towards the air.
