Li Yan carefully recalled the words of the system, and the word "anytime" suddenly jumped into his mind.

Isn't "anytime" the same as "casually"?

Could it be that after the countdown is over, I can continue to stay in the Origin World, and I can go whenever I want?

I understand!

Cooldown countdown!

In other words, the system is a traversal skill, which can be used to shuttle between the origin world and the real world at will, but there is a certain cooldown, and he must wait for the cooldown to end before he can perform the next crossover!

That's great!

After getting this information, Li Yan's face was overjoyed, because, in this way, his time flexibility was greatly increased!

For example, when he is doing something particularly important in the Origin World, even if he doesn't finish it, he can still stay here and wait until it is resolved, and then choose to return to Earth.

Moreover, this is only the primary authority of the origin world.

What about intermediate permissions, advanced permissions, and super permissions?

Is the cooldown time greatly shortened, until the end, it becomes no cooldown, and you can cross when you want?

And will there be no restrictions on carrying items, and you can even bring all kinds of fierce beasts and dinosaurs from the prehistoric world back to Earth?

Thinking of this, Li Yan suddenly had motivation again.

So...... How do I get back?

As soon as this thought came to him, the next moment, the space in front of him began to distort, and a huge dark blue black hole like the first time it had crossed suddenly floated in the air in front of him!

"Do you want to return to the Earth world?"

Of course go back!

Although the prehistoric world is very free and exciting, it is also full of dangers, and Li Yan has lived in the past seven days, and he has not even slept peacefully.

Can you imagine what it was like to hear people snoring in real life and dinosaurs snoring in prehistoric world?

"Goodbye! Brothers, don't miss me too much, wait until I come back to bring you something to eat! ”

After waving his hand, Li Yan gradually walked towards the black hole.

The two dogs watched him walk towards the beach with a cute expression, yes, they couldn't see the black hole.

And at the moment when Li Yan was sucked into the black hole.

Suddenly, his afterglow swept to the sea in the distance, and a huge black shadow flashed from his eyes!

Groove !!

It must be more than 20 meters, right?

Super Big Mac!

It wasn't until this moment that Li Yan remembered that since it was a prehistoric world, there must also be top ocean overlords such as Canglong, Shanglong, and Neptune Dragon!

But he hadn't noticed it before, and even if he did, he would subconsciously choose to ignore it, because most sea creatures couldn't get ashore!

But the dragon is not, the dragon can go ashore to hunt!

The textbook says that this guy even feeds on triceratops!

"It's over, it's over! I thought the edge of the beach was the safest, but now I look at it, it's the least safe! ”

Li Yan looked worried.

Although Canglong rarely goes ashore to hunt for food, anyone who sleeps with a super fierce beast "next to the pillow" will have a feeling of unease!

And just when he wanted to tell the second dog to stay away from the beach.

"Boom!"

With a muffled sound, Li Yan fell to the ground with his buttocks.

He hurriedly looked up, and the familiar living room, the same furniture display, the glare of sunlight shining through the window, even the beer bottles on the floor, and the disgusting smell of leftovers had not changed in the slightest!

It can't all be dreams, right?

Thinking of this, Li Yan hurriedly looked down at his body, although the thatched clothes were gone, the spar on his left arm, as well as the alchemy array in the dimensional space, were still there.

At this time, the system's prompt came again:

"Drop! The host has successfully returned to Earth, and the Origin Crossing Cooldown countdown has begun! ”

"Whew...... Good thing it's all true! ”

The next moment, he called up the attribute board, which showed the time when he could cross next time, which was three days away.

Is it shorter than the cooldown of the origin world?

Li Yan frowned thoughtfully, and immediately communicated his dimensional space, and as soon as he opened it, he could see the three-leaf green pear fruit stuffed inside:

"Great! Sure enough, I brought it back! Find a laboratory to study it, and if I can extract any valuable information, my first pot of gold will come! ”

Thinking of this, he hurried to find his mobile phone, only to find that it was already out of battery.

"I don't know how long it has been, if it's the same as the time flow speed of the Origin World, it will be bad!"

It's not that he's afraid of work, but he's mainly worried about his friends and family, and if they choose to call the police because they can't find him, he'll have to trouble at that time.

So, after charging the phone, Li Yan immediately turned on the TV.

After flipping through several stations, he finally saw the date and time under the corner marker: July 16, 2018!

Just seven days later!

It seems that the speed of time between the two worlds is one to one!

If that's the case, then there's no need to rush to the Origin World first, you have to find a way to sort out the things on this side of the earth first!

Get the logistics done first!

This is a profound truth that Li Yan has realized in the past few days.

Next, he took advantage of the charging of his mobile phone to hurriedly clean up the beer bottles and garbage in the living room.

Fortunately, there was no air conditioning in the rental room, and he kept the window open.

Otherwise, if you sit in the house for seven days, you won't be able to stay!

After finishing the living room, Li Yan hurried to the bathroom and prepared to clean up.

Although I have been bathing at the beach for the past few days, the sea water is not as comfortable as the water heater after all.

Arrived at the sink.

Looking at the wheat-colored skin, stubble, and weather-beaten face in the mirror, Li Yan himself was startled!

No way! Is this handsome man me?

After seven days of devastation in the primitive world, Li Yan was tanned a lot, and his beard and hair were a little messy.

But perhaps because he was often in a hurry and hunted to escalate, his temperament as a weak researcher had long been left behind.

Instead, a hunter with sharp eyes and an aggressive look!

This kind of temperament is very similar to those wilderness anchors, or soldiers who train outside all year round, full of the wildness of men.

But Li Yan is even better than them.

Because, he is the one who has really killed the beast, and he is also an ancient beast: a dinosaur!

After taking a shower, shave off your beard.

Li Yan has noticeably become more energetic and clean.

Back in the living room, the phone was already on.

He opened it to unlock it, and sure enough, in addition to the calls, the rest of the text messages and WeChat have accumulated a lot.

After looking around, he immediately breathed a sigh of relief.

Fortunately, Li Yan usually works overtime in the research institute of the biological company, and his friends only think that he was dragged to the "little black house" again to do something new.

After replying one by one.

He thought about it for a while and decided to call the head of the R&D department.

If he didn't go to work for seven days and didn't have any leave instructions, the supervisor must have thought that he had resigned in anger because he was the team leader.

That's right, he's been fired by SMS notification!
