"Neptune, what's going on?"

Logically speaking, Neptune would notify Gu Ding and Lilliath in advance before the ship started shaking so that they could secure their bodies. However, this time, Neptune did not warn them in advance when the spaceship shook. Gu Ding and Lilliath almost fell, but only Biggie stood firmly on the ground. The soles of his feet seemed to be connected to the floor by a layer of primary power.

"We … seem to have encountered the legendary space-time backtracking …" Neptune's tone sounded a little strange.

"What's space-time backtracking?" Gu Ding had a bad feeling about it.

"Space-time backtracking is a very rare space-time disorder phenomenon in the universe. It will cause the time and space in a certain area of the universe to go back to the past. The area covered by this area can be large or small. A large area may cover the entire star sector, and a small area may only happen in a small village on a certain planet. There are also big differences in the point of backtracking. Sometimes it could be hundreds of years ago, and sometimes it could be tens of billions of years ago. "

"This phenomenon will also cause a Space Loop. We can't escape, and the people outside can't come in, so we can only wait patiently."

"How long does this phenomenon usually last?" Gu Ding could not help but ask.

"It can be a few minutes to a few days. Generally, it won't be too long, so don't be nervous." Neptune himself felt a little helpless. After this phenomenon occurred, the communication network completely failed. He could not get any new information, and he did not know how much time had been backtracked.

"If we've encountered space-time backtracking, why didn't anything happen to us?" Lilliath could not understand.

"When space-time backtracking occurs, some people or things will exist as variables. They are the things that remain unchanged in space-time backtracking. Other people and things will be replaced as constants, such as Derisis … "Neptune's words made Gu Ding and the others look out the window.

"That planet isn't Derisis, is it?" Biggie looked out the window in disbelief. The location where Derisis was previously was replaced by another huge planet. The huge planet was at least thousands of times the size of Derisis.

"That should be Derisis from billions or even tens of billions of years ago. The planet you just left is probably just a meteorite left behind after the planet collapsed," Neptune explained.

"If a constant is replaced, will it disappear forever? Doesn't that mean that every time this kind of space-time backtracking happens, it's a catastrophe? "Lilliath considered this issue.

"After a constant is replaced, the original constant will be squeezed into a parallel space and continue to exist in another form. They don't even know that space-time backtracking has happened. Only someone who has become a variable will know that this has happened. "

At this moment, the ship suddenly shook again.

"Everyone, sit tight. I have to land the spaceship!" Neptune sounded very nervous. "Otherwise, we'll be in big trouble!"

At this time, Liliath also saw the source of the trouble that Neptune had mentioned from the window. It was a giant beast about the same size as Planet Derisis. Its huge head and long tail made it look like a giant blue tadpole that had been magnified countless times. "Is that … a Giant Star Beast?!"

"It's a giant blue whale beast. It usually feeds on meteorites and likes metal meteorites the most. That's why it attacks human spaceships." Neptune explained, "That's why we have to land as soon as possible. Otherwise, the Grey-faced Buzzard will be eaten by it."

Everyone's hair stood on end as they watched the giant beast open its mouth and spit out a terrifying stream of air, sweeping up all the surrounding meteorite fragments into its mouth. If the Grey-faced Buzzard was attacked like that, it would definitely not be able to escape.

Neptune controlled the spaceship and quickly landed on the nearest green planet.

Green planets were usually planets with lush vegetation and were generally suitable for life.

After the spaceship landed, Neptune used some means to determine that the current time backtracking point was 14.6 billion years ago.

Originally, Neptune suggested that the three of them stay in the spaceship and wait for the time to backtrack. However, Gu Ding felt that it was too boring. He decided to use this time to look for mineral veins on the planet to see if there were any energy ores that Robert could use.

The three of them got off the spaceship in a good mood because the oxygen content was very high. Moreover, the planet's air was not toxic to the human body.

Based on the analysis of the soil quality, Neptune roughly guessed the types of mineral veins on the planet. Based on the conditions under which the mineral veins were formed, it was not difficult to deduce the location of the mineral veins.

After specifying the nearest location for Gu Ding and the others, the three of them wandered for about ten minutes before Neptune detected the location of the first mineral vein. It was almost exactly the same as what he had predicted.

"This kind of ore is called Earthly Fire Crystal. It is produced by absorbing Earthly Fire energy all year round. It is a type of energy ore," Neptune explained. "You can try and see if you can put it into Robert's body."

Gu Ding took out the metal ball that Robert had turned into and stuck an Earthly Fire Crystal on it.

One minute, two minutes … They waited for fifteen minutes, but there was no reaction.

"It seems that this kind of ore is useless." Gu Ding shook his head. "Let's continue looking for other ones."

"There's a Rank 8 Gene Body giant beast coming in this direction. Hide for a while!" Neptune's detection radius was increased to a kilometer. In this environment, it was much more advantageous than before.

When the three of them heard this, they scurried up a big tree and used the dense foliage to hide themselves.

A giant beast soon appeared in everyone's line of sight. It was a giant feline with a body length of more than twenty meters. Its movements were terrifyingly fast, and its spotted fur gave off a warning signal.

"It's so beautiful!" Lilliath could not help but exclaim.

At that moment, the feline's ears flicked twice. Then, its gaze fell on the big tree where Gu Ding and the others were hiding, and it pounced on them.

Gu Ding and Lilliath quickly fled while Biggie made his move in an instant. His speed was even faster than the feline, and he instantly appeared below the big cat's throat. His left hand was in the shape of a knife, and he raised it up high. A sharp force instantly gushed out, and directly cut into the big cat's throat. The giant beast's body immediately became exhausted.

Both Gu Ding and Lilliath were a little shocked when they saw what had happened. Biggie's killing of the giant golden alligator was indeed surprising, but everyone thought it was the result of his battle. Now, it seemed that a Rank 8 Gene Body did not even have a chance to attack Biggie. It was a feline gene beast that was one of the best in terms of speed and reflexes among its peers.

"Are you guys okay?" Biggie handed the Energy Crystal from the feline's body to Gu Ding.

"We're fine. It's a Rank 8 Gene Body. Lili and I can't handle it with our current strength." Gu Ding shook his head. He still felt that he was not strong enough.

"Just leave it to me!" Biggie said with an honest smile.

"Biggie, let them handle gene beasts that aren't Rank 8. You don't have to do anything. Take advantage of this opportunity to let the two of them practice actual combat! "Neptune's voice suddenly reached the ears of Biggie and the others.

"That's exactly what I was thinking!" Gu Ding grinned and nodded.
