The void where the earth is located is obviously completely different from the void before Mark, and there is a huge difference in both the rules and the form in which the world exists. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Judging by what Mark had learned in his previous life. If the Earth is a world, then the solar system is a universe. And the sun is the origin of the universe.

It is necessary to reach 11.2 kilometers per second (2) cosmic velocity to leave the Earth, and 3rd cosmic velocity to leave the solar system. This is actually the same as the world master tearing the world boundary membrane, and the universe overlord tearing the universe boundary membrane is essentially the same.

The black hole is far away from Earth, but at the speed of the Mark Void spacecraft, it will not be long.

There are some differences in the void here, and the biggest difference is that you can see a sky full of stars. It gave Mark a sense of going back to his past life.

The thought of seeing the earth in a moment suddenly made Mark's mood suddenly feel an inexplicable excitement. What would happen if we went back to ancient times? Or would we see another self? Is there a heaven and earth vitality on the earth? Would you like to take in a disciple? Leave a small opportunity to come down?

Thoughts of jumbled thoughts filled his mind, making Mark nervous and feeling a sense of homesickness. The two hands clenched and released, and then clenched again, but he didn't notice that his palms were already full of sweat at the moment.

In just a dozen days, the solar system is already close at hand.

The Void Ship plunged headlong into the solar system and flew straight towards Earth. The familiar earth in his eyes is getting closer and closer, and Mark's mood is becoming more and more difficult to control.

A few minutes later, when he flew out of the Void Spaceship, looking at the familiar blue sky and white clouds, and the endless forest below, Mark couldn't help but laugh and yelled:

"I'm finally back!"

Then a low, high-spirited roar sounded on the ground, as if in response, and he looked down, and suddenly the whole person was confused.

"Holy! this-this-this-this is a dinosaur?"

On the ground, a huge dinosaur more than twenty meters tall raised its head to look at Mark. The slender neck stretched out of the forest canopy, and glanced at him a few times, presumably not feeling delicious. Then he walked out and ran towards a small meadow in the forest, followed by dozens of dinosaurs, large and small.

"Am I back in Jurassic?" Mark's eyes widened, and then his soul power swept, and most of the world was suddenly under his soul power scan.

When he came to a conclusion, he froze. This time he was sure he was back in the Jurassic era. There is not a single intelligent creature of reptiles and dinosaurs all over the earth!

Not only that, but there is also a huge gap between the area of the continent and the form of animals and plants from the previous life, which is unimaginable.

However, there was one thing that surprised Mark, that is, the earth actually contained energy gases similar to the Heaven and Earth Yuan Qi. This energy gas is by no means simple, although it is very different from the Heaven and Earth Yuan Qi, it can also be absorbed by the body and change the body's physique.

Then Mark's heart moved, and as soon as he grabbed it, a giant herbivorous dinosaur weighing at least 100 tons was easily caught by him in the air. With a slight finger stroke on its thigh, a wound two or three meters long appeared, and blood suddenly gushed out.

Mark picked up a little blood and put it in his mouth to taste it, then cut off a thin slice of meat and put it under the sun to examine it carefully. After a long time, he put the dinosaur back in its place with a solemn expression. For a moment, he floated in the air in a daze, and fell into deep thought.

The dinosaur's body was much stronger than he had imagined. If you guessed correctly, it should be because you absorbed a large amount of that energy gas and transformed your body. Otherwise, where can the body weighing hundreds of tons be able to withstand this mere two legs?

But Mark remembered that in his later life, humans would never have such a powerful body. In other words, it is very likely that in the next life, this unknown energy gas has disappeared.

It's no wonder that with the evolution of living things, the size of later creatures has become smaller, and the larger creatures are constantly dying out, and I am afraid that this is also related to the fact that there are fewer and fewer energy gases.

The largest mammal, the whale, had to survive in the water, and the elephant, the largest creature on land, was only about ten tons at most.

So why does the energy gas that is so dense now gradually disappear in the next life?

Mark frowned, puzzled.

I came back to see how my friends were doing after I left. But I don't want to go back to the Jurassic era! It seems that God won't let me get my wish!"

Mark shook his head in disappointment, and took one last look at the earth beneath his feet. Born here, raised here, until the age of twenty-three, his worldview, values are cultivated here, it is impossible to say without feelings!

But now it is the Jurassic era more than 100 million years ago, even if he is a ninth-level powerhouse, his lifespan is only 100 million years at most, even if he waits here for a lifetime, he will not be able to see the era when the human race began to flourish.

Sighing lightly, Mark got up and wanted to leave, but as soon as he got up, he suddenly stopped again, thought about it with a complicated expression, then glanced down, and flew away, and soon came to the area where the motherland was located in his previous life.

Although this piece is very different from the landform of the previous life, it still has a vague shadow of the previous life.

"Since you've been back, let's leave something behind. If someone discovers it in the future, it can be regarded as giving that person a chance! However, without vitality in the future life, it is impossible to cultivate. What might you like to leave behind?"

Mark looked down in thought, rummaging through the Ring of Legends, only to find that there was nothing suitable. Either it is impossible to survive for that long, and even if it can survive for that long, it will be of little use to future generations.

Eventually, he flipped over to something, and his eyes lit up. But he began to hesitate again.

After a long time, he turned over his hand and took out the mending stone, sighed and said to himself:

"Anyway, it was originally intended to be left to a certain junior, but my Sai'an family is already the master of time and space, and the combat power and power are already unique in that void, so I don't care if there is such a thing or not. I hope I can wait for a good successor!"

As he spoke, Mark flickered into the ground and went underground until he reached a depth of several thousand meters before he casually dug a large hole with a radius of several hundred cubic meters.

With a wave of his hand, an eighth-level array group was cast, and then he began to condense the ninth-level reinforcement runes bit by bit and began to strengthen this ground hole, which was a fine grinding effort. In order for this cave to last for more than an epoch, it will take a lot of resources and patience to set it up.

For more than a month, Mark had been reinforcing the cave, and he didn't stop until the last ninth-level reinforcement array was set up by him.

A large stone plate made of the seventh-level strange stone Jin Jade Rock was placed in the middle of the cave, and then the goose egg-sized mending stone was thrown in the center of the stone plate.

Mark looked left and right, feeling that it was almost over, and after thinking about it, he took out the last disciple nameplate he had refined. This is a nameplate that has reached the peak holy weapon level, it has no function, and when he first refined, he mainly focused on corrosion resistance and long-term storage.

The nameplate is engraved with a universal lingua franca -- nine! representing his nine disciples.

After leaving some information in the nameplate, Mark placed the nameplate next to the mending stone. One last look around, a space flickered and left the place.

It's all done, it's finally time to leave!

Mark took out the Void Ship and embarked on the road back with mixed emotions.

What he didn't know was that the Heaven Replenishing Stone that he had left behind suddenly emitted a multicolored light just a few minutes after he left, and it began to slowly absorb the energy gas similar to Yuan Qi around him. It's not fast, but it's not slow, it's a little faster than the Earth can release this energy.

If Mark had been here now, he would have come to a conclusion with horror:

If the extinction of the dinosaurs was due to the reduction or even disappearance of this energy in the air, then it was he who caused this change!

In other words, it was this mending stone, or rather, he caused the extinction of the dinosaurs!
