For nearly a month, in addition to eating, drinking, sleeping, and learning the knowledge of the Medicine Sutra, Kong Xuan spent almost all of his time studying the Spirit Sealing Spear.

At the beginning, although he verified that the killing intent could drive the black and white qi in the spirit sealing spear, in real practice, he found that the process was not simple.

Standing straight in the room, Kong Xuan raised the Spirit Sealing Spear to his chest, and then condensed the killing intent in his body and slowly transmitted it to the Spirit Sealing Spear.

After two years of cultivation in the Soul Burial Mountain Range, Kong Xuan's control of his own momentum was very accurate, so controlling the condensation of killing intent and then transmitting it to the Spirit Sealing Spear was not too difficult for Kong Xuan.

With the introduction of the Void Xuan Killing Intent, the originally silent Spirit Sealing Spear emitted a burst of gunfire sounds, and then, a trace of extremely narrow black and white qi emerged from the body of the gun.

"No, although it can be a simple inducement, but just such a little black and white qi can't play any role at all when fighting."

Look at the black and white aura that you won't see if you don't pay attention to it, and a look of bitterness appeared on Kongxuan's face.

For a whole month, he focused on controlling the Spirit Sealing Spear without sleep or food, and he only got such a small reward.

However, in the past month, he has continued to use killing intent to control the Spirit Sealing Spear, although he has not made much progress in the black and white weapon of the Spirit Sealing Spear, but Kong Xuan has found that his own control of killing intent is more comfortable.

Killing intent is a kind of momentum, a kind of iron-blooded cold breath, it is different from spiritual power, it cannot be cultivated by itself, it can only be possessed by people who have really passed through the battlefield and experienced the cycle of life and death.

And this momentum, for those who have not experienced the battlefield, are psychologically timid, and have a weak ability to endure, will have some fatal effects.

"Well, let's take a break, we won't make much progress if we go on this way. ”

With a wry smile and taking his eyes off the Spirit Sealing Spear, Kong Xuan shook his head and walked to the window, his dark eyes narrowed slightly, looking at the scenery above the sky and the clouds.

Although the speed of the Wind Sparrow Beast is extremely fast, for the comfort and safety of the people riding it, the person who built this dwelling has left a formation on the back of the Wind Sparrow Beast that can isolate strong winds.

Because of this formation, even if Kong Xuan stood in front of the window, he only felt a breeze.

The breeze on his face made Kong Xuan feel more comfortable, and the fatigue of studying the Spirit Sealing Spear in the past month has also dissipated a little.

After he blew for a while, he looked sideways at Yixiao's room, and during the time he focused on the Spirit Sealing Spear, he also felt the chill that continued to emanate from Yixiao's room from time to time.

"It seems that with Yu Ye's guidance, Yixiao's cultivation is also twice the result with half the effort, and when he arrives at Nagujia Academy, he has a certain amount of cultivation resources, and I believe that Yixiao's strength will progress even faster. ”

The cold air emitted by Yixiao at this time was obviously much stronger than a month ago, so Kong Xuan could also feel the speed of Yixiao's progress.

"I also have to work harder, I don't want to control it completely, but before I reach the imperial capital, I must control the black and white qi in this spirit spear almost enough."

With a light breath, Kong Xuan once again set his eyes on the Spirit Sealing Spear and muttered in his heart.

Invisibly, Yixiao's progress made Dekong Xuan feel a trace of inexplicable pressure.

"Brother!"

At this moment, an anxious voice suddenly came from behind Kong Xuan, and Kong Xuan immediately turned around when he heard the sound, only to see Yu Ye's ethereal figure appear in front of him.

Without waiting for Yu Ye to explain, Kong Xuan immediately understood what was going on, he casually threw the spirit sealing spear on the ground, and with a pause, he rushed to Yixiao's room.

"Brother Kongxuan"

As soon as he entered the room, he saw Yixiao's somewhat pale face, and the latter was sitting on the ground at this time, watching Kong Xuan walk in and say hello softly.

Seeing this, Kong Xuan's eyebrows suddenly rose, and he hurriedly stepped forward to pick up Yixiao, and then put him on the bed.

"There is no danger to his life, but once he cultivates to the point where his spiritual power dries up, Yixiao will become weak all over his body. ”

Looking at the worried Kongxuan, although Yu Ye on the side was also worried in his heart, he still explained calmly.

At this time, it is useless to say anything else, only to say Yixiao's symptoms as soon as possible is the greatest help to Kong Xuan.

Hearing this, Kong Xuan nodded, put his palm on Yixiao's fair-skinned wrist, and then closed his eyes, sensing the situation in Yixiao's body.

"It's the sequelae of the corpse poison, it's my carelessness, after ten years of erosion, it has caused some irreparable damage to Yixiao's body. ”

After half a ring, Kong Xuan slowly opened his eyes, his fingers gently scraped the bridge of Yixiao's straight nose, and a trace of gloom flashed in his eyes, and he blamed himself.

"Is it really irreparable?"

Looking at Kong Xuanna's face, which blamed herself, but after probing Yixiao's physical condition, she didn't look too worried, Yu Ye couldn't help but roll her eyes, pursed her red lips, and the worry in her heart quietly receded.

This guy is worried about his sister to death, she doesn't believe it, and when she knows that Yixiao's sequelae can't be made up, she can still be so indifferent.

"Hehe, although this sequelae is indeed irreparable, it is not all bad for Yixiao... Sister Yuye, Yixiao, you can cultivate in the future so that the spiritual power in your body doesn't dry up anymore, and Yixiao, your current physical fitness is probably comparable to me before. ”

was seen through by Yu Ye, and a smile instantly appeared on Kongxuan's face, and the gloom in his eyes also disappeared.

"Huh?"

Kong Xuan's words made both Deyu Ye and Yixiao stunned, and the latter raised his head slightly, looking at him, a pair of snow eyes full of doubt and dazedness.

Kong Xuan's physical fitness, Yi Xiao is very clear, if her physical fitness is comparable to Kong Xuan, this is absolutely impossible in Yi Xiao's heart.

"Brother, where did this start?"

Yu Ye also looked at Kong Xuan with a blank face, even with her experience, she had never heard of the fact that being poisoned by corpses could strengthen the body.

"The corpse poison invades the body, although it will erode Yixiao's body and consciousness, but at the same time, it also changes Yixiao's physique, so that the body becomes invulnerable, originally after the corpse poison was dispersed, Yixiao's body should be weak, but because this corpse poison is cold corpse poison, it has eroded Yixiao's body for too long, and the spiritual power in Yixiao's body has a certain adaptability, so when it was expelled, the spiritual power in Yixiao's body gradually made up for the position of the corpse poison, creating Yixiao's snow body, which is the same as the body of the zombie, which is invulnerable, but the zombie is caused by the corpse poison, that is, the corpse gas, and Yixiao is caused by his own spiritual power。 ”

Looking at the blank looks of the two, Kong Xuan said with a smile. After speaking, he took out a dagger from the space ring, put it in front of the two of them, and chuckled:

"When Yixiao's spiritual power recovers, you can try it with this dagger, and it will definitely not leave a single wound. ”
