"This is the black heart stone, the legend says that only the kind of people with a black heart, black to the point of pus, if you die one day, many years later, you will find this kind of stone in it. Wei Mei said lightly.

Ji Jiu's expression froze, and he couldn't resist the idea of strangling her, and then his face returned to normal, and asked, "Then what is the use of this stone?"

As he spoke, he touched the surface of the black heart stone, which was densely covered with layers of ravine-like lines, like small blood vessels, which seemed to beat faintly after being stained with his blood.

"The formation conditions of the black heart stone are extremely harsh, but because of the special material, it is extremely difficult to destroy, and it also has some kind of strange power, you can use it as a refining material. Charm explained.

"Refining materials?" Ji Jiu's eyes flashed, and he also had a plan, "What does the weird power mean?"

"I can't tell you this, poison, curse, bad luck...... It seems possible. Wei Mei recalled for a moment, and said: "A long time ago, the Yan Ling clan had a pitch-black battle axe, which was integrated with many black heart stones, giving birth to an extremely corrosive trickery, even the warriors of the Bridge Raiding Realm had to be careful and did not dare to touch it easily. ”

"Trickery?" Ji Jiu carefully stroked the stone in his hand, and was silent, the Huanyan Sword in his hand could only be regarded as a half-finished Dao weapon, and its material was no longer enough to continue to support the sacrifice, and he didn't know what kind of changes would occur after integrating into the Black Heart Stone, and he was also a little worried that it would explode the Huanyan Sword.

After a while, Ji Jiu accepted the Black Heart Stone, since it was a very precious thing, he naturally would not use it easily, and it was really a waste to use it on the Huanyan Sword.

What's more, in Yu Liang's memory, it won't be long before an ancient artifact will be unearthed in the Central Heavenly Domain, its power has already made the bridge robber power crazy, if he plans to obtain that weapon, it will not be too late to use the black heart stone at that time.

In the next few days, Ji Jiu fell into cultivation again, his own strength is still too low at present, although there is a pre-stage of soul melting, but what he has to face is all kinds of god-transforming powerhouses, carelessly, a little more strength, but also a little more protection.

Wu Lingyun next door is also stepping up her time to cultivate, and her strength is also slowly improving, Ji Jiu's original intention was to soften her heart, let her be less vigilant, and it will be much more convenient to pick in the future, but the charm of the ghost stirred up, and it had the opposite effect, making Wu Lingyun and herself more estranged.

The days flowed quietly, and three days passed in a blink of an eye.

"The little flower of ice and fire that was devoured in the Rong family's cemetery at the beginning, the energy it formed was stored in the body, and it still couldn't be absorbed for a while, if it could, use itself as a furnace, sacrifice it, and refine it all. ”

Ji Jiu was thinking again.

"Ji Jiu, talk to me. In the past three days, the first time she spoke, I don't know if it was her own illusion, Ji Jiu felt that her voice was beating with naked loneliness.

"What are you talking about?" replied Ji Jiu Ai ignored him, and as he spoke, his fingers began to hook up in the air, and the complicated gestures swam by, and at the same time, a dazzling point of light also flashed out of sight, like fireworks.

"I feel like you're the same as I am. "It's all the same loneliness." All my people are dead, and now I am the only one left. ”

"Well, it's different, I'm not alone. Ji Jiu still lowered his head, trying to hook the runes on his body, the lines disappeared into it, penetrated into his body, and his skin faintly glowed, like exquisite porcelain reflecting the sun, dazzling and scorching.

"Duplicity. The ghost's voice fell silent again.

Ji Jiu no longer paid attention to her, and as the lines of the Dao disappeared into his body, he felt that there was a faint heat and cold alternately coming from his body, and the spiritual power from the dantian position was surging wildly, like tidal waves.

Disheveled!

The faint blue flame suddenly ignited from his body, and Ji Jiu's clothes were burned in an instant, revealing a slender and slender body, and wisps of flames jumped on his body, as if they were emerging from under the skin, and in some places there were even scorched black marks, emitting the smell of roasting.

Ji Jiu suffered this great pain, his face turned pale instantly, and even the sweat droplets of beans began to seep out of his forehead, he really didn't expect this process to be so tragic, it was comparable to torture.

After a few breaths, he began to adjust to the pain, and the slight trembling of his body also decreased, and then another burst of flames rose up, wrapping around his body without stopping.

Using his body as a furnace, he also lost Ji Jiu what he thought of, and he dared to do it, if he was not careful, it would be a serious injury, and Ji Jiu's body also appeared fragment-like lines, as if it was about to crack...... Immediately, a majestic burst of vitality rushed out from the depths of the body and began to soak into the cracked body.

A red-blue intertwined air flow traveled along Ji Jiu's limbs and hundreds of remains, and it was the energy of that little flower of ice and fire.

"You're crazy. The charm couldn't help but mutter.

In Ji Jiu's dantian, there was also a great change at this moment, he was originally a demon body, and he couldn't open up the spiritual sea, but at this moment, there was a sound of breaking the ground, and the vast and boundless earth cracked and was torn apart.

The sea of spiritual qi gushed out from the crack, gradually converging into a small lake, but there was a fiery red circulation in the blue of the lake, and a huge inner pill fell from the sky and smashed directly into the lake.

The Soul Palace Realm martial artists in this city all raised their heads at this moment, and involuntarily looked in the direction where Ji Jiu was, in their perception, it was like a quarantine area, and the aura in the air disappeared in an instant, as if it did not exist.

"Which senior broke through?"

After a few hours, the flames all dissipated.

Ji Jiu wiped the blood from the corners of his mouth, stood up, and then took out his clothes and put them on, if you look closely, you will find that there is a faint blue and red halo on his skin at this moment, and the abundant and powerful power is hidden in it, as if a punch can shatter the sky.

"The ice source of my Ice Spirit Clan's High Priest and the Fire Source of the Fire Spirit Clan's High Priest ended up cheapening this demon. The ghost's gaze passed through the ice coffin and landed on the white chess pieces inside the Sumeru Ring, and it flashed in a complicated flash.

Ji Jiu clenched his fists concentratingly, and his palm suddenly made a crisp sound of bones, and it could be seen that this power was absolutely good, and even the void was wrinkled like paper.

"This is the promotion to the late stage of soul melting?" He closed his eyes and sensed the situation of his current body, the spiritual sea was rippling in Tian Dan, the spiritual energy was surging, a huge inner pill was rolling in it, swallowing majestic spiritual energy, and a pitch-black soul palace above suppressed everything, standing still.

Ji Jiu couldn't help but be stunned by this, even he couldn't believe it, he was promoted to the late stage of soul fusion so quickly?

"Don't be confused, you have absorbed the lifelong essence of the two Bridge Robbery Realm powerhouses, if you can't be promoted, I'm afraid there will be a real problem. The charm explained to him.

"And you should have deep cultivation experience, unlike other martial artists who will encounter cultivation bottlenecks. ”

"And the two of them's perception of ice and fire......"

Ji Jiu stretched his waist when he heard this, and smiled.

Since he has such strength, he will definitely go on his innocent birthday in a few days.
