"Master, you can do secondary side quests now, but the quests are random." Xiaohong explained with a smile.

This second-level side quest couldn't be chosen independently, which made Xu Chuan frown slightly.

Assigning tasks randomly, it does increase the difficulty.

"Master, are you now accepting secondary side quests?"

"Accept!" Xu Chuan said without hesitation, of course, he had no choice.

"Start randomly selecting a secondary side quest and get the quest: Build a short-range portal!"

"The mission rewards 5,000 system coins."

"Master, do you accept this task?" Xiaohong asked again.

"Of course I do!"

Xu Chuan still did not hesitate, although he didn't know how this ghost portal was built.

"The acceptance task is successful, and the start of the task is three days."

All side quests have a time limit, and they are generally not long, this task is a three-day deadline, but it is not beyond Xu Chuan's imagination.

"Xiaohong, how can I build a short-distance portal, give my master a little hint." Xu Chuan asked Xiaohongdao.

"Master, you can follow the principle of a short-distance teleporter."

As soon as these words came out, Xu Chuan suddenly realized.

He had a short-range teleporter on his wrist, and its principle was basically the same as that of a short-range portal.

Therefore, Xu Chuan can completely imitate the short-distance teleporter to build a short-distance portal.

This task is actually to test Xu Chuan's imitation ability!

"Okay."

Xu Chuan hurriedly started to act, but he didn't plan to build a portal in this villa in front of him, but planned to build it in his home in Mirage City.

It's the safest place to be.

Moreover, there is also his wife Xia Wan here to take care of him.

Back at his home in Mirage, the first thing Xu Chuan did was to use the supercomputer at hand to analyze the various parameters of the short-range teleporter.

He quickly got all the parameters and was ready to experiment!

In order to create a short-distance portal based on a short-distance teleporter, it is not a simple copy, but also requires a lot of experiments.

He first built a portal the size of a palm for experiments, and at most he could only teleport very small items.

The interior is pitch black, as if it could swallow light, and is full of mystery.

It is said that all portals, whether they are short-range portals or portals that can cross the stars, are made according to the principle of black holes.

And the black hole in reality can swallow everything.

Anything that comes close to it will be swallowed up, and not even the light can escape.

Therefore, Xu Chuan is still a little afraid of this palm-sized portal.

In case you inadvertently create a real black hole, will you use it as the center to instantly swallow everything around you?

Will this harm the whole planet?

"Master, you think too much...... At your point, you still want to build a real wormhole? Xiaohong appeared beside Xu Chuan, revealing a look of contempt.

"It's better to be careful." Xu Chuan's heart didn't beat, and his face didn't blush.

He then began to test the portal for success.

He took out a ping-pong ball and put it inside the portal......

Sou!

With a slight sound, the ping-pong ball disappeared suddenly, but Xu Chuan waited for a long time at the exit and didn't see the ping-pong ball appear.

That is, the experiment failed.

The ping-pong ball didn't know where it was teleported...... It could be somewhere on Earth, somewhere in the universe, or maybe even another parallel world.

If that ping-pong ball is a person, the consequences are unimaginable......

Just thinking about it, Xu Chuan felt scared for a while.

Thankfully, he had the foresight not to rush into it, but instead built a small portal for experiments.

"Failed......" Xu Chuan was slightly disappointed.

"Master, it must be your coordinates that have been entered incorrectly!" Xiaohong saw the problem at a glance.

If you want to build a portal, you definitely need to set a coordinate.

Otherwise, the devil knows where he would teleport to.

Xu Chuan also entered the coordinates just now, but it seemed to be an invalid coordinate, so the ping-pong ball was missing......

It seems that Xu Chuan has always been a weakness in the coordinates.

He hurriedly revised the coordinates, and after confirming the doubt, he activated the portal again.

This time, he still chose a table tennis ball as the experimental subject, anyway, this kind of thing is very cheap, and it is not a pity to lose it.

"Teleport me!"

Xu Chuan is looking forward to the result this time.

Sou!

The ping-pong ball was immediately sucked in by the portal, and almost instantly appeared on the other side of the room, which was the target designed by Xu Chuan, and it was also the place where the coordinates pointed.

The portal is not far from this destination, one on one side of the house and one on the other side of the house.

"Success?"

Xu Chuan thought he had succeeded, and showed an excited expression.

Portals are too simple, but they only succeeded after two experiments.

However, when he picked up the ping pong ball, his face suddenly darkened.

The ping-pong ball instantly turned into powder and fell to the ground, and even the scum could not be found.

In other words, this ping-pong ball was definitely cut by the power of space during the teleportation process just now, so it was directly shattered.

It seems to be intact, but the interior has long been scarred.

"Master, you've failed again, this time you must have made a mistake in the parameters......" Xiaohong reminded, a hint of contempt rising on her face.

"Don't be complacent, master, I will succeed next time!" Xu Chuan said viciously to Xiaohong, but he was also a little anxious in his heart.

This secondary side quest is really not easy.

It's so hard to just have one!

This time, Xu Chuan carefully modified all the parameters before restarting the experiment.

This time, he thought he was flawless and would succeed.

"Husband, what are you doing, I'm off work."

At this time, Xia Wan actually walked in and saw a palm-sized black door, and felt puzzled.

And, Xiaohong disappeared as soon as she came in.

Without Xu Chuan's special order, Xiaohong would not have appeared in front of anyone, because this was Xu Chuan's biggest secret.

"Wife, you may not know, I'm working on a short-distance portal right now!"

"When I succeed in my research, I can build this kind of portal all over the world and make money."

"And I'll be the greatest scientist in the world."

Xu Chuan looked at Xia Wan with a smile on his face, and he couldn't help but be proud in his heart.

Of course, in front of his wife, he has to pretend to be great.

Xia Wan stretched out a slender hand and touched Xu Chuan's forehead before she frowned and said, "Husband, you didn't burn it?" ”

"What do you mean?"

"Scientist, husband, just be your boss, don't think nonsense." Xia Wan obviously didn't believe Xu Chuan.

Of course, she can't be blamed for that. No one will believe it.
