Dong Xin's face suddenly became extremely ugly, the "Ghost Shadow Umbrella" was blown up, and the blood light emitted from the body of the instrument was bright and dark, obviously damaged, and his heart ached for a while, the "Ghost Shadow Umbrella" was what he was preparing to use to cross the catastrophe, and after careful inspection by his spiritual sense, he breathed a sigh of relief, the damage was not serious, and it only needed to be put into the "Yin Vein" for a few years to recover.

Dong Xin didn't expect that Changsun Rong would break through the "Thousand Souls Yin Spring Prison Spirit Array" that he had carefully laid out by detonating the magic sword, and he admired this woman's courage a little, but even if he broke the "Thousand Souls Yin Spring Prison Spirit Array", there was still a strong prohibition at the exit of the cave, and he was on the side to contain Changsun Rong and not want to escape.

Seeing that the "Hanji Ice Sword" blew itself up and destroyed the entire "evil array", Changsun Rong breathed a sigh of relief and a heartache at the same time, the "Hanji Ice Sword" followed for nearly a hundred years, and it turned into ashes in a breath, and soon Changsun Rong put away the complicated emotions in his heart.

Eldest Sun Rong understood that the top priority was to kill this evil cultivator in order to get rid of the crisis completely, the spiritual power in her Purple Mansion was not abundant, and the recovery pills she carried on her body were also exhausted, so she could only fight quickly, and the situation would only become more and more disadvantageous if she dragged it on.

It's just that this evil cultivator named Dong Xin is not weaker than her, and he has lost the "Hanji Ice Sword", and if he wants to kill this person in a short time, he can only use the Dan Qi of "Luan Yuan Dan" again.

Eldest Sun Rong's eyes suddenly looked at Dong Xin coldly, and first drove the spiritual power of Zifu to send out a six-grade high-grade spell "Streamer Star Needle", hundreds of sharp "Ice Needles" appeared like stars in the sky, and then turned into streamers, overwhelmingly blasting towards Dong Xin.

After the eldest grandson Rong sent out the "Streamer Star Needle", he immediately urged the "Luan Yuan Dan" suspended in the center of the Purple Mansion, extracted a part of the Dan Qi from the blue mist pill qi emitted by the "Luan Yuan Dan", and at the same time extracted the spiritual power of Sancheng in the Purple Mansion, and cast the advanced spell "Group Spirit Exterminating Ice Spirit Spear" of the "Spirit Slayer Ice Spirit Spear".

I saw that six "Soul Slaying Ice Spirit Spears" condensed in front of Changsun Rong at the same time, and they quickly rotated and flew towards Dong Xin with the frost in the sky, and the air condensed to form six white tails visible to the naked eye, and the temperature of the air in the cave dropped sharply, and the ground and walls of the entire cave mansion instantly condensed a layer of frost, and the thick vine body of the "Xuanyin Corpse Vine" also shrank into a ball.

Dong Xin snorted lightly, and then used the "Yin Yuan Shield" to cooperate with the "Ghost Shadow Umbrella" to block these hundreds of sharp "ice needles", Dong Xin's face suddenly changed, he felt that Changsun Rong burst out with a terrifying spiritual power, and seeing six "Spirit Slaying Ice Spirit Spears" appearing in front of Changsun Rong, Dong Xin couldn't help but feel creepy, and a chill surged in his heart.

Dong Xin didn't dare to hold it up, and immediately released the only six "Yin Demons" left in the "Ghost Shadow Umbrella", and drove the six "Yin Demons" to meet the six "Ice Crystal Spears".

A series of loud noises of "bumping", the violent air wave shook Changsun Rong and Dong Xin back several feet in the air, and bursts of black smoke came out of the center of the explosion, which did not disperse for a long time, and a huge pit exploded on the ground.

Dong Xin was afraid for a while, the eldest grandson Rong was trapped in the "Thousand Souls Yin Spring Prison Spirit Array" for several days, and when the spiritual power of the Purple Mansion was exhausted, he could still cast such a powerful spell, if he hadn't reacted in time, he might have died at this moment.

Then there was a burst of heartache, and the only six remaining "Yin Demons" of the "Ghost Shadow Umbrella" were also consumed, and the grade of the body plummeted, and the power dropped significantly.

Eldest Sun Rong was also extremely heartbroken, the secret technique she had used to consume a large amount of Dan Qi was easily resolved by Dong Xin, and she couldn't help frowning, extremely anxious.

The "Luan Yuan Dan" in her Purple Mansion is a superb "Xuandan" given to her by the Taishang Elder "Hanluan Zhenren" after she successfully built the foundation, and it took more than 300 years to condense these Dan Qi, which is extremely valuable and an important means to improve the grade of "Jindan".

The eldest grandson Rong is a "Dan Xiu", and the difference between "Dan Xiu" and the traditional "Fa Xiu" is that the "Origin Fa Dan", and when the "Fa Xiu" cultivator reaches the late stage of foundation building, he gathers a large amount of mana, essence, essence blood, and essence to condense a "Natal Yuan Dan" in the Purple Mansion, and when he reaches the realm of Pseudo-Dan, he begins to prepare for the tribulation wholeheartedly.

"Dan Xiu" is to carefully refine a "Xuandan" through various spiritual materials after the foundation is successfully built, and it is included in the "Natal Yuan Dan" that is bred in Zifu instead of Fa Xiu and condensed, which is called "Natal Xuandan".

The timing of the "Xuandan" is different, some cultivators will be included in the Purple Mansion in the early stage of foundation building, and some cultivators will have to wait until the middle stage of foundation building, or even the late stage of foundation building. When to include the "Xuandan" in the Purple Mansion generally depends on the qualifications of the cultivator himself.

Because once the cultivator puts the "Xuandan" in the Purple Mansion, it will greatly hinder the improvement of his own cultivation, and the "Xuandan" will not only take the initiative to attract the mana stored in the Purple Mansion, but the cultivator also needs to consume the essence qi, essence blood, and essence yuan from time to time to conceive this "Xuandan", which is both time-consuming and labor-intensive.

"Xuandan" will only be assimilated in the Purple Mansion after nearly a hundred years of warm cultivation, and then it is equivalent to a part of the cultivator himself, so that it can be called "Natal Xuandan". Continue to consume mana, essence, essence blood, and essence to give birth to the "Natal Xuandan", in order to give birth to the precious "Dan Qi".

In addition to being used to increase the power of spells and resist the "Heavenly Tribulation" of the Dan, the most mysterious thing is that it can improve the level of the "Golden Pill". The stronger the "Dan Qi" condensed by the "Natal Xuandan", the higher the grade of the "Origin Golden Pill" that was successfully produced by the Tribulation.

Changsun Rong first blew up the "Hanji Ice Sword", and then cast the spell "Group Spirit Slayer Ice Spirit Spear", these two attacks have consumed nearly half of the "Dan Qi" of the "Luan Yuan Dan", how can Changsun Rong not be heartbroken?

Moreover, these two attacks also consumed a large amount of mana from Changsun Rong, and at this time, the mana contained in her purple mansion was only less than forty percent, on the other hand, the evil cultivator could absorb the rich "yin qi" around her to restore her own mana, and the form was extremely unfavorable to her, and she couldn't help but feel more and more bitter in her heart.

Changsun Rong's face was cloudy, and she hesitated in her heart to think about whether to use that move, the price of that move was too great, and the charging time was too long, the other party would definitely take the opportunity to attack, it was too dangerous, but at this time, it was time for life and death to be on the line, and she had no other better way to break the game, it seemed that she could only rest assured, life and death depended on the sky.

The eldest grandson Rong and Dong Xin looked at each other, and they didn't mean to make another move, Dong Xin was absorbing the rich "yin qi" in the air to replenish the mana, while the eldest grandson Rong was very hesitant and hesitated to make up his mind, and the dim cave suddenly fell into silence.
