From Xiang Liang's words, they also thought of two people, one was Chasing Wind who had advanced to the third-grade low-level Lingfeng of the ground level.

As for this second one, it is Xiao Tianxing, who has a quasi-earth-level weapon, Wind Fang.

However, Chasing Wind had already followed Huanqing at this moment and went to the periphery of the Hun Fortress to reconnoitre, so it was impossible for the advanced weapon to be his Lingfeng at all.

After thinking of this, everyone's eyes immediately fell on the Lanling Chamber of Commerce on the other side.

"Could it be that Tianxing's wind teeth are advancing at the moment?" Guessing in his heart, Xiang Liang immediately rushed to the Lanling Chamber of Commerce on the other side.

It was also when Xiang Liang set off that Mu Xing also found the source that the wind whirlwind was looking for.

"Sure enough, it's the Lanling Chamber of Commerce on the right side!"

Finding the source of this wind whirlpool, Mu Xing's heart also concluded that the weapon that was being advanced was Xiao Tianxing's wind fangs.

"Let's go to the Lanling Chamber of Commerce!" he greeted everyone, and the figure of Mu Xing also disappeared in place.

Hearing the words of Mu Xing, everyone guessed in their hearts that the weapon that was being advanced at the moment was the wind tooth that Xiao Tianxing had.

The group hurried to the Lanling Chamber of Commerce on the other side, and immediately noticed that the outside of the stone room where Xiao Tianxing usually cultivated was already covered with very strong wind source qi.

At this moment, outside the gate of this stone chamber, Tie Shan and Ran Yun and his party were all standing here at a loss and staring at the gate of the stone chamber in front of them.

They didn't know what was going on at all, so they didn't dare to open the door of the stone chamber in front of them easily for a while.

When they came to the backyard of the Lanling Chamber of Commerce, they immediately felt a very strong wind source qi.

"Such a strong wind source qi, how did this kid Tianxing do it!?"

After continuous speculation, everyone also came to the door of the stone room, and then Mu Xing also asked Tie Shan.

"Iron Mountain, how's the situation inside?"

Hearing Mu Xing's inquiry, Tie Shan also shook his head at him.

"I don't know! From just now, I felt that there was a very strange fluctuation emanating from the stone room of Tianxing's cultivation. ”

"When we came out, we found that the courtyard was already full of wind source qi. ”

"Brother Mu Xing, how do I feel that this situation is somewhat similar to the situation of the advanced knowledge of ground-level weapons recorded in the book?"

"It's not similar, it's just that the sword spirit of the earth-level weapon is advancing, if I'm not mistaken, I'm afraid it's the wind fang in Tianxing's hand, and it's in an advanced process at the moment. ”

"Ahem, cough ......!" Hearing these words of Mu Xing, Tie Shan choked on a mouthful of saliva at that time.

"Tianxing's wind teeth are advancing!?How did this kid do it!!?"

"Now is not the time to talk about this, I have to find a way to go in now and see how Tianxing is doing. After saying this, Mu Xing also looked at Xiang Liang and Hua Mian next to him.

"Mr. Xiang Liang, Hua Mian, let's go in and see how the situation is, remember not to urge the source qi at will, from now on we can only use our strength to resist!!"

"Understood!" At the same time, Xiang Liang and Hua Mian also came to Mu Xing's side.

"Dai Jian, Wu Kuang, Brother Tie Yan, the three of you immediately stabilize the surrounding source qi, remember to let the wind system source qi concentrate here, don't let the source qi collapse. ”

"Understood!" At the same time, the figures of Dai Jian and the three disappeared in place.

"Yi Han, Yi Shui, Fei'er, Yao Xue, Ge Wen,...... A few of you, hurry up and disperse the crowd of onlookers around the Lanling Chamber of Commerce. ”

"Understood!"

After arranging everyone's work, Mu Xing, Xiang Liang, and Hua Mian glanced at each other and were ready to deal with emergencies.

After completing the exchange in his eyes, Mu Xing took a step forward and placed his hand on the door of the stone room.

With a slight force of the palm, the closed door began to slowly open a gap.

"Crunch!" the door of the stone chamber slowly opened, and then a strong aura immediately emanated from the crack.

Just this trace of power immediately made Mu Xing's brows furrow.

Although Mu Xing's appearance of opening the door of the stone chamber seems to be very relaxed, but whether it is easy or not is only clear in Mu Xing's own heart.

When he pushed the door of the stone chamber just now, Mu Xing was already very clearly behind the door of the stone chamber, and he felt a very huge force blocking here.

Fortunately, his strength is strong enough, if an ordinary person comes here, it is almost impossible to push open the door of the stone chamber by simply relying on his strength.

The strong aura swept through, and immediately rushed through the bodies of the wooden torturers, and then also greeted Ran Yun and the others behind them.

"Woo woo!" The strong aura passed through his body, and Ran Yun and a few children of the personal guards immediately felt a feeling of tightness in his chest.

"Huhuhu...!" After a few heavy breaths of breath, Ran Yun gritted his teeth to maintain his figure and barely stand up.

As for the other children of the guards, they were all half-kneeling on the ground at this moment.

"Goh...!" he swallowed hard, and an expression of disbelief appeared on Tie Shan's face.

"Sure enough, the ground weapon is advancing, but how did Tianxing do it!?"

Between the constant speculations in his heart, Tie Shan also noticed the situation of Ran Yun and the others.

"You guys, get out of here now! I'm afraid the next situation is no longer something you can bear. ”

"No, I'm going to stay here!I'm going to wait for Tianxing to come out!" Regarding Tie Shan's persuasion, Ran Yun immediately expressed his attitude.

"We're not leaving! we're all going to stay here!" After Ran Yun, the other members of the pro-guard team also expressed their attitude.

"You have to think clearly, the pressure will only increase in the future, and you can't resist with the source qi, you ......"

"Hehe, Uncle Shi, isn't this a rare opportunity to train yourself?" chuckled at Tie Shan, and Ran Yun also gritted his teeth and stood up.

Looking at Ran Yun beside him, and then at the members of the pro-guard team who insisted on staying in place, Tie Shan's face also showed a relieved smile.

"Whew...!" let out a sigh of relief, and Tie Shan's gaze was once again at the door of the stone chamber.

At this moment, the door of the stone chamber had been fully opened, and the strong and abnormal aura began to emanate from inside.

"What a strong breath!!The dragon pupil of Tianxing has actually become stronger with the growth of strength!"

With a sigh of amazement, the eyes of the Mu Xing few also fell on Xiao Tianxing, who was concentrating on controlling the dust of the source core bone at this moment, and merged into the wind tooth sword body.

When they saw the situation clearly, they were immediately shocked.

It turned out that at this moment, Xiao Tianxing had a trace of blood hanging on the corner of his mouth, and a line of blood and tears also flowed from his dragon pupils.

"Huhuhu!" The violent breathing made Xiao Tianxing's chest fall together, but his teeth were clenched together, and he always held his last breath.

"This kid, it's too reckless!" frowned and complained secretly, and Mu Xing also glanced at Xiang Liang and Hua Mian next to him.

After understanding the meaning of Mu Xing, Xiang Liang and Hua Mian also slowly approached Xiao Tianxing's side.

The teeth clenched together, and Xiao Tianxing desperately urged the source qi, squeezing the dust from the shattering of the source core bone, and guiding them into the sword body of the wind fang.

Compared with Xiao Tianxing's constant guidance, the sword body of the wind tooth also exuded bursts of cyan brilliance, absorbing these dust on his sword body.

"It's so strange!Why, in the later stage, this wind tooth actually absorbed my source qi!?"

Between the constant speculations in his heart, Xiao Tianxing was still gritting his teeth and insisting on continuously delivering source qi.

However, although his current cultivation had improved a lot, he was only at the peak of the sixth order of the Shen Mind Realm, and he couldn't afford the total amount of source qi needed to advance the Wind Tooth at all.

However, it was too late to regret it at this moment, and after feeling that his qi sea had almost dried up, Xiao Tianxing also had the idea of guiding the power of the source marrow.

Of course, if he really channeled the power of the Source Marrow, those powers would be enough to elevate the quality of the Wind Fangs.

But as a direct result of this, the extremely valuable power stored in Xiao Tianxing's body could no longer transform his body.

Just when Xiao Tianxing wanted to use this power, the three of them also rushed here.

Feeling the situation of the advance of the wind teeth, Mu Xing couldn't help but be afraid for a while, if it wasn't for the abnormal movement of the outside world that reminded them in time, Xiao Tianxing's final result was likely to be two.

One is the failure of the Wind Fang's advancement, which leads to the destruction of the entire sword.

The second is that he insisted on helping Fengya to advance, causing his source qi to be drained, thus becoming a wasted person, and even losing his name.

"Squeak!" Between clenching his teeth, Xiao Tianxing also noticed a few wooden punishments, and then his eyes were directly on Xiang Liang's body.

"Grandpa Xiang, I can't hold it anymore, hurry up and convey the origin to me!!" It took almost all the strength of Xiao Tianxing to squeeze out such a sentence in his mouth.

After hearing Xiao Tianxing's words, Xiang Liang did not rush to make a move, but looked at the wooden punishment next to him.

After all, in this Hung Ya Fortress, only Mu Xing has independently completed the casting of ground-level weapons, and now his opinion is the most important.

After perceiving Xiang Liang's gaze, Mu Xing also nodded lightly.

After getting Mu Xing's consent, Xiang Liang no longer hesitated, and immediately urged his source qi to transport it into Xiao Tianxing's body.

The majestic source qi continued to pour into Xiao Tianxing's body, and his almost dry sea of qi also shone again.

As soon as his teeth bit the tip of his tongue, the pain also made Xiao Tianxing regain his spirits, and then the eight desolations and five qi in his body slowly operated, and Xiang Liang's attributeless source qi was also transformed into wind source qi, which was constantly transported out by Xiao Tianxing.

"Buzz Bell, Buzz Bell, Buzz ......" The tremor on the sword body continued to intensify, and the dust from the shattering of the source core bone was also adsorbed on the surface of the sword body of the wind fang.

The textures continued to flash, and on the white sword body, there were also more supple lines.

After seeing these lines, Xiang Liang's pupils immediately shrank, because he already felt a trace of familiarity in them.

"Tianxing! you are so reckless! you actually used those fragments of the source core bone to improve the quality of this wind fang!!"

"Don't say it's with your current cultivation, even with the old man's cultivation, I don't dare to say that I can control it!!"

Secretly complained about Xiao Tianxing in his heart, and Xiang Liang also increased the transmission of source qi again.

His eyes were wrinkled as he looked at the scene in front of him, and Mu Xing's two eyes were also full of horror.

Because at this moment, on the hilt of the sword of the wind fang, the word 'wind' has been very clearly displayed, and the word 'wind' also exudes a kind of glowing green crystal brilliance.
