Then there's the issue of energy.

The power consumed by the entire monitoring and infrared early warning system every hour is far from being met by a few power banks commonly used by Shi Junjun.

The several sets of lithium batteries sent to her through the pocket portal can only last no more than forty-eight hours according to the theoretical energy consumption of the whole set of equipment, and the actual may be a few hours less.

Although Shao Wei said that he could send a few more sets of lithium batteries to extend the power supply time of the monitoring and early warning system, Shi Junjun had other plans.

"You mean, hydropower?"

"Yes." Shi Junjun on the other side of the screen clicked down and flipped the camera, showing Shao Wei the turbulent river in front of him, "I know only a limited amount of theoretical knowledge of hydroelectric power, but looking at the scale and flow rate of this river, there should be no problem with the basic conditions." ”

"Then it's a device problem."

Shao Wei, who was in the real world, smiled bitterly.

After traveling through another world, the pocket portal did provide them with a lot of convenience, but now the size limitation of this golden finger has seriously restricted the development process of her and the greenskinned dwarfs in the other world.

"According to the description of the oversized hamster before, it is very likely that the previous generation of time-travelers has a golden finger with a similar function to our pocket portal."

Shao Wei, who was looking through the previous copy of Shi Junjun's record information, noticed that the previous generation of time-travelers had left enough food for the oversized hamster Wangcai to consume food for two years.

Without considering any unknown otherworldly storage type of magic, having a golden finger with a similar function is obviously the most plausible explanation.

"How did that lord leave me that pile of food......

Wangcai's round rat eyes rolled white, and then stretched out his paws to point to the huge grotto that had almost hollowed out half of the rock wall at the far bottom of the cliff where the waterfall was:

"It was in that place that the adult first asked me to turn around and close my eyes, and at that time I looked back because I was curious, but the adult waved his hand, and made such a big grotto on it, so frightened that I quickly turned my head and didn't dare to look again, and when he told me to turn around and open my eyes, it was already full of food......

No wonder it's a hero who can defeat a legendary monster like a dragon...... As soon as the emotion is casually shot, it is already the power of the humanoid shield machine.

After lamenting the explosive force value of the previous generation of time-traveler compatriots together with Shao Wei, Shi Junjun asked the previous generation of time-traveler compatriots if they usually took out something strange and strange, not like a product of this world.

"Doesn't look like a product of this world?" The fleshy rat's face was full of confusion, "You mean it's similar to the magic props you usually pull out......"

The gap between the characteristics of modern industrial products and the other worlds, even the monster Wangcai can find a huge difference, probably "it's a rare magic prop", but it can't make all the guys who witness those modern industrial products dispel the doubts in their hearts, but they are forced to accept this statement because they can't find a reasonable explanation for the huge gap between the two worlds.

In the last attack on Goblin Village, there were several green-skinned dwarfs who picked up Shi Junjun's mobile phone and got in touch with Shao Wei, including broccoli.

Although she explained it with "It's something that can communicate with humans who are also in possession of this magical item far away", and asked the greenskins to keep the secret for her, no one knows if they are really convinced.

"So." A trace of hesitation flashed on her face, and she finally took out a few things from her pocket, "The adult in your mouth, Wangcai, did you use a similar ...... back then?"

"Lord Shi Junjun, how can you have the same magic props that the adult used to be, and there are so many?!"

Wangcai's eyes were full of adoration, "No wonder he was able to take out so much food like that adult......"

After hearing the exclamation of the oversized hamster Wangcai, Shi Junjun was already able to basically determine that the previous generation of time-travelers had the same golden finger as himself.

Because what she came up with was the best-selling mobile phones on the market 20 years ago.

After putting back the old mobile phone that Shao Wei had retrieved from a second-hand mobile phone store at a tattered price, the girl nervously asked the next question:

"So that one wears ...... Did the Lord you speak of say anything about being able to expand the teleportation space......"

"Aren't you supposed to ask human magicians this kind of question?" Wangcai, who was full of admiration just now, suddenly turned into a disgusted face, "I'm just a rat and mouse who has spent most of my life in this forest, and I don't know magic myself, where do I know so many things about magic, and that guy has said so much, where will I remember......"

Seeing that the oversized hamster Wangcai seemed to implicitly mention the statement of the pocket portal, as a magic from another world, Shi Junjun thought about it and changed the way of expression:

"The adult you mentioned shouldn't have been able to conjure so much food in such a short period of time from the beginning, so in your memory, did he shorten the time to conjure food after experiencing any events?"

The pocket portal is the only one of her secrets that is as important as her identity as a traverser, which is why she asks Wangcai in such a roundabout way.

"Hmmm......"

After pondering and scratching his ears and cheeks for a while, the oversized hamster said uncertainly: "Time has passed a little too long, and I can't remember the rat clearly......"

The human adult, who couldn't remember his name, seemed to have to tell him to wait for a while before calling him over for dinner.

It's just that later, as they walked more and more places, his waiting time for dinner seemed to get shorter and shorter, and then he just asked him to close his eyes, and in the blink of an eye, a large pile of food appeared in front of him.

As for why...... If you can fill your stomach, why care about things that have nothing to do with filling your stomach?

"Think about it." The girl once again resorted to the food temptation method, "If you remember where this change occurred, then other more delicious foods are not impossible to ......"

"Rat rat, I remember!"
