In the places where the bones were concentrated, there were many cracks in the originally smooth stone walls.

"Could it be that the cracks on the stone walls on both sides are caused by sword qi?" Su Sheng said in surprise

"That's right, and these sword qi are all emitted from the deepest white wall. Mu Ling said

Su Sheng also looked at the white wall, and said strangely, "Is this stone wall like you, and it also has its own consciousness, and can automatically emit sword qi?"

"Stinky boy, how can this stone wall be compared to the original spirit, you think that the machine spirit is so easy to be born!" Seeing that Su Sheng put it in the same category as that stone wall, the wood spirit immediately beat Su Sheng fiercely

"If it's not a spiritual thing, how can it emit sword qi?" Su Sheng asked rhetorically

"Hmph, that's because within three hundred steps of this stone wall, there is a formation, and it is this formation that stimulates the sword qi on this stone wall. Mu Ling snorted coldly and explained

In fact, the reason why Mu Ling was able to notice the strangeness here so quickly was also thanks to this formation.

This formation, which originally existed to cover up the sword qi, became the key to seeing through it in the hands of everyone in the formation of the wood spirit.

"Formation, within three hundred steps!" Su Sheng was startled and looked at his feet, because of the previous incident, he was almost more than one hundred and fifty steps away from the stone wall, didn't it mean that he was still within the control of the formation!

As if knowing that Su Sheng was worried, Mu Ling said, "Stinky boy, don't worry, the real danger of this formation is only within a hundred steps, and after more than a hundred steps, it will be fine." ”

"Then what now?" asked Su Sheng, who was a little settled in his heart, again

"Come closer, and see what's on that stone wall!" the wood spirit began

When Su Sheng heard this, he had to raise his feet and walk towards the bottom of the cave again, but this time he was more careful than the last time, basically counting his steps, and walking very slowly.

Su Sheng didn't want to feel the sword qi that could hurt him with that blow again.

And when Su Sheng finally barely reached the position of about a hundred steps on the white wall under the reminder of Mu Ling, he could already vaguely see that there seemed to be some fonts on the cave wall.

"If you go to fifty steps, you can pass me a set of sword tricks!" A line of awe-inspiring words was engraved on the stone wall

"This ......" Su Sheng was also shocked by this line of words

"Stinky boy, you are lucky, I also said what kind of treasure is after this formation, it turned out to be a set of sword technique inheritance, judging from the fact that he can leave sword qi on the stone wall, this person's swordsmanship should be extremely strong. Although when facing Su Sheng, Mu Ling looked like a cow, but when it came to this stone wall at this moment, there was a hint of respect in its tone, in addition to appreciation.

Su Sheng also felt the respect contained in Mu Ling's words, and also cast a look of admiration at the stone wall.

Within a stone wall, he was able to leave sword qi, which he had never heard of before.

Moreover, after getting along with Mu Ling for such a long time, Su Sheng knew how arrogant this guy was, and even Mu Ling was full of praise for this person, even if he didn't understand the reason, he knew that this person was extraordinary.

Such a person, the sword trick left behind, is naturally not an ordinary thing.

And if you want to get this set of sword tricks, according to the senior's meaning, you must have the ability to enter the position of fifty steps into this stone wall.

But at this moment, Ren Susheng's desire is higher, and he doesn't dare to approach at will anymore after suffering a loss.

After a moment's thought, Su Sheng picked up a piece of broken bone from the ground and threw it towards the cave wall.

"Bang!" Soon after the broken bone came out of its hand, it was shattered by an invisible breath.

"What a powerful sword qi!" Su Sheng, who had been watching intently, couldn't help but let out a sigh of admiration

Next, he tried it a few more times, and he was probably convinced of Mu Ling's words, as long as he was a hundred steps away from the cave wall, it seemed that he would not be attacked by sword qi.

Knowing this, Su Sheng was completely relaxed.

However, although he knew that there was an extraordinary sword technique engraved on the cave wall, Su Sheng at this time did not have the heart to break into the sword formation, and he was relieved, and now he was worried about Xiangxiang who was still unconscious outside the cave.

For a few days, Xiangxiang has been unconscious, and her face has become worse and worse, and Mu Ling has also said that Xiangxiang's condition is very bad and cannot be delayed for too long.

Now that he understood the situation in the cave, Su Sheng summoned Flip Feather in, and specially instructed Flip Feather not to come within a hundred steps of the stone wall.

Although Feather is still full of jealousy of this cave, with Su Sheng's guidance, it is quite intelligent and relieved.

After reminding him to turn over the feathers, Su Sheng took local materials again, built a bone bed in the middle of the cave for Xiangxiang with the pile of white bones on the ground, and then found some dead leaves to spread on it, so he could stop.

"Mu Ling, what's Xiangxiang's situation now, what should I do next?"

In the past few days of escaping, even if Su Sheng asked Mu Ling, the other party only said that it was because of the fire vein that caused him to go mad, and asked him to find a place to settle her as soon as possible, and he didn't want to say more if he asked again.

Su Sheng knew that Mu Ling just didn't want him to be distracted by too many things, but now that he had settled down, he should also know the specific situation.

"Well, remember the time before, when she was casting your weapon, she went mad, right?" Mu Ling also spoke, and said slowly

Of course, Su Sheng remembered what Mu Ling said, and asked, "I know, but it's been so long since that incident, what does it have to do with Xiangxiang's current situation?"

"You listen to me carefully!" ignoring Su Sheng's urgency, Mu Ling said slowly, "That time, this girl just came into contact with the power of fire that overflowed when some blood wood burned, and she went crazy, which shows that her system was already a little out of control at that time. But you were busy with the forge, and knowing that this would not be useful and would distract you, so I didn't tell you. ”

Su Sheng also thought about it carefully, Xiangxiang's madness at that time was indeed a little weird, and at that time he only said that it was an accidental reason, but he didn't expect that Xiangxiang's fire vein problem was already so serious at that time.

"You understand now, this girl's fire vein body is already a little out of control, with the current strength of the Xiang family, hmph, there is no ability to control this kind of thing at all. Mu Ling said with some contempt, and then said coldly, "To put it mildly, with the strength of the Xiang family, I am afraid that I can't even maintain this girl to this extent." ”

When Su Sheng heard this, he couldn't help but be surprised, "It's so serious!"

"Hehe, what do you think, to put it bluntly, this kind of system shouldn't be born in such a small family!" Mu Ling said unceremoniously

Mu Ling's words, Su Sheng was a little inexplicable, the Xiang family seemed to him in the past, but in Mu Ling's eyes, it was so inexplicable!

Su Sheng hurriedly asked again, "Then why was Xiangxiang okay before?"

"That's because there's a seal in this girl's body!" Mu Ling said

"Seal!" Su Sheng said in surprise, he had only heard of these things that Mu Ling said occasionally, and he had never come into contact with them before

"Although this seal is not too clever, it does have some effect on suppressing the explosion of her fire veins, I don't know who planted it!"

"Didn't her mother Xiang Tianfeng get this seal?" Su Sheng wondered

"Hmph, with her little strength, I'm afraid she doesn't even have the qualifications to cultivate this seal!" Mu Ling disdainfully degraded the patriarch of the number one family in Bloodwood Town to worthlessness

Compared to Mu Ling, the more he spoke, the more energetic he became, and the more Su Sheng listened, the more he felt hit!

He asked himself that among all the people he had seen, this Xiang Tianfeng's strength could enter the top five, but such a person didn't even have the qualifications to practice this seal.

A simple seal in Mu Ling's mouth directly lowered the identities of those masters he had seen.

'What kind of seal is this!' Su Sheng also sighed in his heart
