"Oh no!" Sensing the abnormal situation of the word 'wind', Mu Xing's heart was really surprised and happy.

But to say more, it is still surprise that occupies the largest part.

"This wind tooth has already crossed the level of the third-grade low-level of the earth-level, and I am afraid that it has reached the peak of the third-grade second-level at this moment!!

"If that's the case, I'm afraid it will be difficult to support Mr. Xiang Liang's strength alone!"

"Whew...!" Just as Mu Xing had just finished speaking, a violent wind source qi also poured into the stone chamber from the outside world.

Feeling the fierce wind source qi that frantically poured in, the horror in Mu Xing's heart was once again raised to a higher level.

"I've actually started to absorb the source qi in nature, is it possible that this wind tooth has to advance again!?"

After thinking of this, Mu Xing immediately looked at Xiang Liang, who was helping Xiao Tianxing to deliver source qi.

Sure enough, when Mu Xing looked at Xiang Liang, he immediately found that Xiang Liang's face had changed.

And at this moment, there was a strange change on the sword body of the Wind Fang, and a very special sound also floated out from the Wind Fang.

"Whew!" the sound of a wolf howling reached the ears of the wooden torturers, and immediately made their spirits tense.

Because in the midst of this wolf howl, they seemed to feel the wind teeth in front of them, and it was no longer a sword at all, but a living wolf.

The clearest thing about this situation is the wood punishment who knows the most about ground-level weapons, and his face has changed greatly at this moment.

"It's actually been successfully advanced, it seems that there is still room for upward improvement in this fang!"

While he was in doubt, Mu Xing immediately quickly thought of a solution to the situation in front of him.

However, at this moment, the fierce wind source qi that kept pouring into the stone chamber also began to fade little by little.

"Hum...!" A light tremor came from the sword body of the Wind Fang, and the dust of the source core bones, as well as the fluorescent green points of light, also perfectly integrated with the sword body.

Clear textures appeared on the blade of the Wind Fang, and the pattern formed was like words, like some kind of strange rune.

"Goh...!" Looking at these runes, Mu Xing was incredulous even if he was frightened, and swallowed a mouthful of saliva that didn't exist.

He is no stranger to this textured wood punishment, because there is also such a texture on his wasteland.

"It's actually the Source Spirit Texture, it seems that this Wind Tooth is already a genuine third-grade mid-level weapon. ”

"But looking at this posture, the wind teeth still have to be promoted upward, which means that the wind teeth couldn't advance before, I'm afraid it's because the strength of the sword body has not been reached. ”

"Since it's just that the strength of the sword body has not been reached, doesn't that mean ......?"

Glancing at the wind teeth in front of Xiao Tianxing again, Mu Xing suddenly remembered that it had been in Dong Ting's hands for a while.

And later, Xiao Tianxing also told himself that Dong Ting seemed to care very much about this fang.

"Could it be that the sword spirit above this wind tooth has reached the level of the ground level, and is just waiting for an opportunity?"

"With the eyesight of the predecessors of the Winter Pavilion, it is natural that they will not be so interested in an ordinary sword, since this is the case......"

After a quick flash of thought in his mind, Mu Xing also came up with a solution that might work.

After thinking of this method, Mu Xing immediately raised a question to Xiao Tianxing.

"Tianxing, now do you have a way to bring this wind tooth outside?"

Nervously hearing Mu Xing's question, Xiao Tianxing immediately gave his own answer.

"No problem, but I have to keep my source gas delivery uninterrupted, or I won't be able to do it. ”

"Now the wind teeth are a little out of my control!"

"Sure enough, every weapon that advances to the ground level will test its master in this way. After knowing it in his heart, Mu Xing's eyes were also on Xiang Liang's body.

"Mr. Xiang Liang, you ......"

Regarding the words of Mu Xing, Xiang Liang immediately understood the meaning.

"General Mu Xing, please rest assured, the old man can still hold !!"

After receiving Xiang Liang's affirmation, Mu Xing stopped talking nonsense, and directly gave instructions for the next step.

"Okay! Now stabilize your mind, keep the source qi in a constant state, and then slowly move outside. ”

"Whew...!" Almost at the same time, Xiao Tianxing and Xiang Liang were also ready.

"Grandpa Xiang, you can move now!"

After receiving Xiao Tianxing's signal, Xiang Liang also maintained the transmission of source qi at the current amount, and then began to move his body.

With Xiang Liang's movement, Xiao Tianxing also began to move his body.

Both hands were still trying to maintain the transmission of source qi, and the wind teeth were always suspended in front of Xiao Tianxing.

"Everyone get out of the way! everyone go farther away!" quickly rushed out of the stone room, and Hua Mian immediately notified the people waiting outside.

Looking at the nervous expression on Hua Mian's face, Tie Shan and Ran Yun didn't dare to ask at all, and immediately withdrew their figures backwards.

After Tie Shan and Ran Yun and the others withdrew, the figure of Mu Xing also appeared in the courtyard, and then Xiang Liang also retreated from the stone room.

And not long after Xiang Liang came out, Xiao Tianxing also maintained his source qi and continued to wrap the wind teeth, and walked out of the stone room.

"Buzz Ring! Buzz ....." A strange tremor came into everyone's ears, and the wind teeth that had changed in front of Xiao Tianxing also appeared in everyone's sight.

"It's... Is this really a wind tooth!?" exclaimed in his heart, and Tie Shan immediately observed it seriously.

When he found out that the wind teeth had undergone a fundamental change, his tears almost fell.

"I didn't expect me to be Tieshan, today I am really fortunate to be able to see the whole process of a weapon advancing to the ground level!"

For Tie Shan's sigh and surprise, Xiao Tianxing and they didn't have any thoughts, because at this moment, all their attention was on the wind teeth in front of them.

When Xiao Tianxing brought the wind teeth to the courtyard, the surrounding wind source qi immediately surged towards him.

However, this time, these source qi did not enter his body, but were directly infused into the sword body of Wind Fang.

"Whew...!" The violent wind swirled in the yard, and immediately blew the flowers and trees planted in the yard to the ground, and even some flowers and plants were uprooted by the whirlwind.

And just as the wind teeth were constantly rotating in front of Xiao Tianxing, the huge wind whirlwind in the air also found the target it was looking for.

"Huhuhuhu...!" A huge whirlwind rushed straight down, and immediately rushed towards Fengya and Xiao Tianxing.

The strong wind immediately caused the entire fortress to enter a state of flying sand and rocks, and almost all the doors and windows opened by the wind were constantly closed and opened by the wind.

Regarding the 'chaotic' situation in the fortress, Mu Xing didn't know anything at all, what they cared about was whether Xiao Tianxing could hold up the next things.

Looking up at the wind whirlwind rushing down overhead, Mu Xing immediately looked at Hua Mian on the other side.

"Do it!"

After receiving the signal of the wood punishment, Hua Mian's body immediately erupted with a strong source qi.

However, the momentum that Hua Mian broke out was not to help Xiao Tianxing, but to point directly at the huge wind whirlwind in the air.

"Huh!" The powerful source qi flew up instantly, and immediately blocked the wind whirlwind rushing straight down in the air.

At the same time as he was brought to Hua Mian's side to act, Mu Xing's figure also came to Xiao Tianxing's approach in a flash.

"Tianxing, now we have to go to the air and let the wind teeth be instilled by that huge wind whirlwind in the sky, so that it can smoothly advance to the level of the earth level. ”

"But when the Wind Fang is instilled by this Wind Tooth, it will also be thrown into the Tempest, and the Wind Fang will most likely be out of your control. ”

"Do you understand what I mean by that?"

Gritting his teeth to maintain the source qi in front of him, Xiao Tianxing also listened to the words of Mu Xing into his ears word for word.

"I understand! This is the inevitable process of making the Wind Tooth advanced, and it is also a test of whether I can control the Wind Tooth after the advancement. ”

"That's right, that's right, I don't have time to talk to you now, but I want to tell you that if you're ready, I'll send you up to meet the test!!"

As soon as the words of the wooden punishment landed, Xiao Tianxing directly gave his own answer.

"I'm ready, send me up now!"

"Sure enough, it's still so stubborn and resolute!" After sighing in his heart, Mu Xing's figure retreated slightly, and then a thin source qi gathered on his hands.

After casting a glance at Xiang Liang, this piece of source qi in Mu Xing's hand also appeared at Xiao Tianxing's feet.

"Tianxing, you must hold on!" After praying secretly, Mu Xing also urged the source qi to lift Xiao Tianxing's figure up.

The figure slowly floated upward, and Xiao Tianxing didn't care about the things around him at all, just focused his attention on the wind teeth in front of him.

Staying not far from Xiao Tianxing, Xiang Liang was also trying his best to maintain the output of source qi, and now he had thoroughly experienced how much power was needed to advance a weapon to the ground level.

Just from just now to now, one-fifth of the source qi in his body has been channeled into Xiao Tianxing's body.

However, Xiang Liang knew that in the next time, his source qi would enter a state of more rapid consumption.

However, thinking about his own strength, he could actually help a weapon to advance, or an earth-level weapon to advance, Xiang Liang's heart was also throbbing.

The figure slowly floated upward, and finally Xiao Tianxing, with the help of Mu Xing, also came to a height of thirty zhang from the ground.

After reaching this height, Mu Xing also looked at Hua Mian on the other side.

After seeing Mu Xing's gaze, Hua Mian also made corresponding preparations.

"Tianxing, now the test is about to begin. Next, it's up to you!"

"Understood!" After agreeing to Mu Xing, Xiao Tianxing's face also crossed a trace of perseverance and determination.

The brilliant golden crystal source qi continued to leak out from the dragon pupil, and immediately wrapped Xiao Tianxing's entire body.

Feeling the huge consumption of source qi in Xiao Tianxing's body, Xiang Liang immediately increased the delivery of his source qi.

Seeing that Xiao Tianxing was ready, Mu Xing also sent a signal to Hua Mian, and at the same time, he was also prepared accordingly.

The advancement of ground-level weapons is inherently a very difficult thing, and the risks involved in this are also well known.

With Xiao Tianxing's current cultivation, this hidden risk has undoubtedly expanded several times again.

What he has to prepare now is that if the Wind Tooth Advancement fails, he will take Xiao Tianxing out of that danger as soon as possible.

And just as Mu Xing was getting ready, a figure in a pale blue robe also appeared in the sky not far away.
