With the appearance of the word "cast", the power of time around Cheng Feng's body began to fluctuate violently.

Immediately afterwards, his spiritual power seemed to be pulled by a mysterious force, and it was strangely detached from his body, and his gaze was replaced by eyes with condensed spiritual power.

In his sight, the scenery in the valley began to change rapidly, flowers blooming and falling throughout the year, the occasional demon beast, and the birds chirping in the air, the picture quickly jumped and flew backwards in the back of time.

And his physical body had already disappeared inexplicably, and it was obvious that his spiritual power was in a special state and was rapidly flipping through the past events in Tongtian Valley.

"Ding!"

"Hint: Player level 49 currently consumes 1 million points ...... to level up!"

"Hint: Experience reduced by 1 million ......!"

"Hint: Experience Reduction ......!"

A system prompt appeared, making Cheng Feng only feel that his heart was dripping blood.

However, as the scenery of the Tongtian Valley changed in his sight from time to time, he had roughly determined the level of upgrade experience consumption.

"Spending almost 3 million XP can turn back time by a year...... But apparently it's only limited to letting the psychic see the past! ”

"If you want to return the physical body to the past, I'm afraid the consumption will have to increase at least a hundredfold, right?"

Cheng Feng thought in his heart, if he wanted to see the scene of the battle between the Netherworld Sword Lord and that demon beast thirty years ago, he would probably consume almost 100 million upgrade experience!

"I TM can only get more than 20 million upgrade experience by killing the Demon Emperor, but fortunately, there are about 130 million experience at level 49, so I shouldn't have to worry about dropping the level!"

Now, Cheng Feng has no way out, gritting his teeth and continuing to turn back time, the picture continues to jump quickly in front of his eyes.

In the time lapse, he saw all kinds of demon beasts haunting the valley with his own eyes, and even saw many pictures of demon ** matching, which is called a rough one.

Similarly, he had seen many human cultivators fighting or training in the valley.

"It's miserable...... That female demon beast was actually taken by several male demon beasts in turn! ”

"Holy? Is this a caravan? Why did you say that you didn't go to the mainland with a caravan, so you went to Tongtian Valley? Attacked by monsters, right? ”

"Huh? These people should be from the same sect, and it seems that they came to Tongtian Valley to train...... That female disciple is good-looking! No way? The female disciple was knocked unconscious by a male disciple...... No way? Those male disciples knocked down the unconscious female disciple? ”

At this time, the picture that Cheng Feng's spiritual power saw was only what happened in the past, not that his spiritual power really traveled back to the past through time and space, that is to say, although everything he saw had really happened, it was actually illusory.

The screen is still beating, and Cheng Feng's upgrade experience is also being consumed at a very fast speed.

10 years ago!

20 years ago!

Finally, after about 90% of the level 49 upgrade experience was consumed, Cheng Feng finally saw the picture he wanted to see.

I saw that in that picture, a huge demon beast was lying in the valley of Tongtian, and the demon beast was like a maggot maggot magnified countless times, looking hideous and disgusting.

However, the aura on its body was quite powerful, perhaps it was because of its powerful aura that apart from it, Cheng Feng did not see other demon beasts within a radius of several thousand meters.

"Eighth-Order Starry Sky Behemoth...... Looks like a maggot? This should be the demon beast that the Nether Sword Lord said, right? ”

"Could it be that the previous generation of Nether Sword Master lost the Dongluo Sword when he fought with it?"

Cheng Feng was overjoyed in his heart, because it was a relationship of going back in time, and the picture that Cheng Feng saw at this time might have been the picture after the battle between the Netherworld Sword Lord and the Demon Beast.

At this time, the demon beast had dense wounds on its body, the ground in the valley was cracked, the cliffs on both sides collapsed, and the sword marks and traces left by the explosion were clearly visible.

There was no one who seriously injured this demon beast in the picture, and Cheng Feng didn't see any trace of the Dongluo Sword.

"A little further!"

Cheng Feng didn't stop the power of time, and once again moved the time forward.

"Ding!"

"Hint: Players cost 300,000 ...... to level up experience!"

With a system prompt, the picture in Cheng Feng's line of sight changed again.

At this time, there was one more person in the picture besides the demon beast, and the aura on that person's body was extremely gloomy, and he was fighting with the demon beast with a long sword in his hand.

Judging from the attack methods he used, it was quite similar to the Netherworld Sword Lord who had died in Cheng Feng's hands before.

Although this person was slightly inferior to the demon beast in his shots, it was not much different, and he was definitely a master of the eighth-order Star Swirl realm...... Judging from this, he must be the Nether Sword Master of the previous generation.

"Finally found it!"

Cheng Feng was overjoyed and said with a smile: "Then the weapon in his hand...... It should be Dongluo Sword, right? ”

The picture jumped too fast before, and there were some details that Cheng Feng couldn't notice at all.

At this time, the picture returned to the Netherworld Sword Lord and the Demon ** Hand, Cheng Feng reversed the time hourglass, and directly looked backwards from the time when the Netherworld Sword Lord and the Demon Beast had just fought, and the magic of this time power was no longer a time rewind.

The Netherworld Sword Lord and the demon beast were fighting fiercely, and Cheng Feng's attention had been watching the Dongluo Sword in his hand, for fear of missing a single detail.

One person, one demon ** hand is very intense, at the beginning it was comparable, but after just a few tens of minutes, the Netherworld Sword Lord has gradually fallen into a disadvantage.

Blood was splattered, and wounds appeared on the demon beast's body, but the appearance of the Netherworld Sword Lord was even worse than that demon beast.

"Boom!"

With a loud bang, the Nether Sword Lord was swept away by the demon beast, and a mouthful of blood spurted out in the retreat, and his body smashed the cliff more than a hundred meters away.

"Damn it!" The Nether Sword Master spurted out a mouthful of blood, and the whole person looked extremely languished, obviously the blow just now had seriously injured him.

The demon beast also slowly landed on the ground of the valley at this time, wheezing violently, although it seriously injured the Netherworld Sword Master, it also consumed a lot, and it seemed that it was planning to seize this opportunity to recover a little.

This picture is also the picture when Cheng Feng saw this demon beast for the first time through his spiritual power.

"It looks like the power of time was moving too fast just now, and I missed some details!"

"But it's not too late to take a closer look!"

Cheng Feng said to himself, and then a few seconds later, the demon beast once again soared into the air and pounced straight towards the Netherworld Sword Lord hundreds of meters away.

It was only a few hundred meters, and it was just a matter of a moment for the eighth-order Starry Sky Holy Beast.
