[The sky is gloomy, the rainstorm is coming, pat the old horse who is sitting down, you hurry up. Not long after walking, a ruined old house came into view......]

......

[A pair of sisters and brothers under the eaves are obviously refugees, their expressions are alert, their eyes are constantly changing, and they seem to have some kind of secret hidden on their bodies......]

......

[This child's left leg has a wound that has not healed for a long time, and you wanted to treat it kindly, but you accidentally found something buried in it......]

......

"Senior...... Why!"

In Mi Mengjiao's unbelievable eyes, Song Yifei pulled out a metal iron ruler that was half an inch long and as black as ink from Mi Lindong's calf muscles.

"Giggles!"

The pain caused by the tearing leg made the unconscious Mi Lindong clench his teeth unconsciously and made the sound of teeth rubbing.

"It should be that your family was deliberately hidden in order to avoid being discovered! Your brother is in a coma, and he is also affected by it!"

After bandaging Mi Lindong's wounds, Song Yifei said with emotion.

......

[The unique metal material and exquisite craftsmanship show that this short ruler is unusual. It may have something to do with your pursuit for days, and you curiously injected true qi into it......]

......

"This thing is probably the key to the Emperor's Tomb?"

Through the prompts given by the system, Song Yifei secretly guessed in his heart.

He flicked the metal ruler with his fingers, and there was a dull humming sound on it, which was indeed quite different from normal iron tools.

Song Yifei followed the system's prompts and began to continuously inject true qi into the short ruler.

At this time, Mi Mengjiao had already used the dry grass in the corner of the room to simply make a bed next to the bonfire, and put Mi Lindong, who was still unconscious, on it.

After it was true that Mi Lindong was fine, she sat cross-legged on the side and listened to Song Yifei speak.

"I didn't expect my dad to ......"

At the moment when she saw the metal ruler, Mi Mengjiao's doubts for days had actually been solved.

Why did Mi Lindong suddenly suffer a leg injury a month ago!

Why did Daddy suddenly want to send them away!

And why Mi Lindong's body has not improved, and he will be in a coma and fever from time to time!

It turned out that everything was because of this short ruler!

It's just that she never thought that her father, who is usually amiable, could do such a cruel thing.

"Senior, are all those people looking for this thing?"

Perhaps Song Yifei's first impression of Mi Mengjiao was easier to get along with, so she couldn't be too afraid, and she spoke more straightforwardly.

"That's right!"

Song Yifei didn't care much about Mi Mengjiao's attitude, he nodded, still paying all his attention to the short ruler in his hand.

I don't know what material the metal ruler is made of, no matter how much True Qi he inputs, it is like a stone sinking into the sea.

I don't believe it anymore!

Song Yifei was ruthless in his heart and increased the injection of true qi.

"Senior, what is this iron ruler?"

Mi Mengjiao really wanted to know what kind of magic this iron ruler had, attracting so many peeps and causing her family to be ruined.

"Emperor Shenwu, do you know?"

Hearing Mi Mengjiao's inquiry, Song Yifei did not hide it, and briefly talked about the imperial tomb and the key.

"I see!"

After learning the ins and outs of the metal ruler, Mi Mengjiao was silent for a long time.

She finally understood why her father was reluctant to hand it over despite knowing the danger.

This kind of great treasure has an irresistible temptation for any martial artist.

"Senior ......"

Mi Mengjiao was about to open her mouth to speak, when a sudden change occurred.

The metal ruler that absorbed Song Yifei's true qi finally reacted.

Airplanes!

On the surface of the swarthy metal ruler, a golden light suddenly flashed, outlining twelve small characters with iron paintings and silver hooks.

"The magic knife was born, the living beings were devastated, there was no heart, no saint was not pressed!"

"What do you mean?"

Looking at the bullish words on it, Song Yifei was confused.

It took a lot of true qi, and I thought that there was going to be some earth-shattering movement.

Mi Mengjiao's gaze was also attracted to the past, forgetting to speak. At this time, in addition to being shocked, she was similar to Song Yifei, and she was also blindsided.

"If this thing is really the key, I feel that the meaning in this sentence is that there is a murder weapon hidden in the mausoleum, warning latecomers not to enter!" Mi Mengjiao frowned and said guessingly.

"Hmm!"

Song Yifei pinched his chin and thought for a while, feeling that this should be what it meant.

"Huh?"

Just as I was thinking about what to do next, the small golden letters on the ruler slowly dissipated. And the metal iron ruler instantly melted into a black liquid, and quickly wriggled into a quaint black knife.

Airplanes!

In the face of the sudden change, when Song Yifei didn't know what to do, a Hongda knife intent burst out from the black knife.

Boom!

A magnificent, domineering, and invisible sword intent burst out with an incomparably domineering slashing sword that emptied the clouds and cracked the clouds and trembled with gold and iron!

At this moment, the sun and moon were not shining within a radius of ten miles.

At this moment, the Grandmaster's heart swayed within a radius of a hundred miles, and there seemed to be an overwhelming, ruthless terrifying sword light in his eyes!

At this moment, the entire ruined Buddhist temple and the nearby mountains were filled with a cruel edge that tore the sky apart, as if the whole world could not carry this sword intent.

It seems that the next moment, it will be torn to pieces!

At the moment when the sword intent was emanated, in Song Yifei's spiritual world, there was a furious knife roar that tore through the mountains and the sea, rushing everywhere. The entire illusory spiritual space was cut out of thousands of knife marks that were visible to the naked eye.

These shadowless and textureless knife marks, as if they were alive, meandered and flowed on the spiritual barrier, stretching and contracting!

In the heart-wrenching ruthless knife intent, Song Yifei's hair, face, and robe were all cut and damaged by the ubiquitous, shadowless and textureless sharp knife intent!

Song Yifei is like a flat boat in the midst of a raging tsunami, which will be destroyed at any time.

The small black knife was just lying quietly in Song Yifei's palm, but in all his senses, it was knife intent, knife momentum, knife qi, and knife roar!

At this moment, his eyes, ears, spirit, and skin were all covered by the Dao Dao sword intent that was sweeping back and forth, tearing the heavens and the earth, drowning and devouring all things.

Wherever the sword intent went, the air disintegrated and collapsed!

Under the emanation of the sword intent, his mind was snatched away, and the spiritual world was split out of countless holes that did not know how deep, countless treacherous undercurrents, blazing flames, and distorted and floating rays of light, just like lightning and fire, suddenly changing, and frantically destroying!

[You never thought that this peculiar short ruler actually contained a wisp of sword intent of Emperor Shenwu, which was a test for ordinary grandmasters, ten deaths......]

"Grass, can you prompt it earlier next time!"

Under the burst of endless domineering sword intent, Song Yifei's spiritual world collapsed.
