After Lu Cheng negotiated with the princess, Lu Cheng wanted to invite the princess to the research base on the earth to talk in detail.

As a result, when Elena plucked up the courage to pass through the portal, as soon as she stepped on one foot, Lu Cheng felt the magic in her body rapidly decrease.

This made Lu Cheng quickly pull her out of the portal.

"The same holder of the Holy Crystal will consume exponential mana through the portal?"

Lu Cheng pondered the golden crystal on the back of his hand, the attempt just now consumed a lot of Lu Cheng's magic power.

To be exact, Elena alone needs to consume the same amount of mana as five to six people, which is almost a quarter of the mana that Lucheng currently has.

"You shouldn't be that heavy."

Lucheng initially thought that the mana cost was calculated based on the weight of the object, but it seems that this calculation of the cost is not as simple as Lucheng thought.

Humans need to enter portals to consume more mana than objects, and this same Crystal holder consumes five or six times more mana than ordinary humans to enter portals.

As for resources such as food and equipment, they require very little energy.

"Heavy? Am I going to take my armor off? ”

Elena said that she was going to take off the armor on her body, but this armor was too cumbersome, and when Elena wanted to take it off, she was like a tortoise that had fallen to the ground on its back, and she wanted to try to regain the uncomfortable feeling of turning back on the front.

"There's no need, I've already told the relevant person in charge of the state about your situation, and they need a little time to make a decision."

Lu Cheng fiddles with the hand-held camera that the pictorial used before, and all the recorded content in the camera is in the SD card.

It includes the entire conversation between Lu Cheng and the princess, after which Lu Cheng recorded a detailed explanatory video.

The description includes the current state of the Kingdom of Scarre, the Bloodcrystal Disaster and its characteristics, plans to expand the portal's power in the later stages, and Her Royal Highness's request for assistance.

After recording this, Lu Cheng sent the SD card back to the institute through the portal.

"Captain, is it enough to rely on video data alone?" The iron ring beside Lu Cheng asked loudly.

Although the hoop couldn't understand what Lucheng and Elena were talking about, it didn't seem like Lucheng was going to let Elena go to Earth's research base.

"Of course, the research base of the earth has already begun to discuss how to deal with the Blood Crystal Beast, but the battlefield intelligence is insufficient, and I need to send something back to discuss it later." Lu Cheng said.

"That road city, the food we need..."

Elena quietly listened to the discussion between Tiehuan and Lu Cheng, and she didn't understand what was being said between the two, but Elena still remembered Lu Cheng's promise of 'food but not shelter'.

"Wait another ten minutes, and my regular contact with that side will be in two hours."

Lu Cheng glanced at the watch in his hand, and the time on Earth was seven o'clock in the evening.

"Ten... Minute? Elena was puzzled when she heard the unit of time.

Lu Cheng would translate the language into the one she could understand, but she still couldn't understand some earth-specific proper nouns.

"Just wait a little longer." Lu Cheng changed his way of saying something that Elena could understand.

She didn't ask any more questions, but just looked at where her soldiers were resting.

Pictorial and Kite in Lucheng's squad check on the health of her soldiers, while General Hubert follows him to reassure them.

"And Lu Cheng, I want to ask the priest of the Soul God behind you to heal the wounds of our soldiers."

When Elena looked at Lucheng again, her eyes turned to Noi, who had been hiding behind Lucheng.

She had noticed Noi's presence from the time she spoke to the Lucheng team, the young priest who was either hiding behind Lucheng or behind the pictorial.

In short, he refused to communicate with her.

"Priest of the God of Souls? Noi? ”

Lu Cheng turned to look at Nuo Yi, she had been in a state of sleepiness just now, but the arrival of the Kingdom Army made Nuo Yi stay behind Lu Cheng with a strong sense of sleepiness.

It's like being afraid that Lu Cheng will sell her to the Kingdom Army while she's asleep.

"Can you heal a kind of magic?"

Lu Cheng half-knelt down and looked at Nuo Yi and asked.

"The priests of the god of souls are all proficient in healing magic, and they can heal any injury, and we were originally ordered to find the priests of the god of souls." Elena said immediately.

What diseases can be cured? This again enters the category of unscience.

But there are too many unknowns about the magic of this world, and Lu Cheng can't be sure if she's exaggerating in her claims.

"Is it true?" Lu Cheng asked again.

Under Lu Cheng's questioning, Noi immediately wrote a paragraph in his notebook.

'The God of Souls has given me the power to heal all things, but this power comes at a cost, and it costs to heal multiple wounds, but if you want me to heal those soldiers, I'm willing to use these magic. ’

Price? Lu Cheng suddenly looked at the aging skin on Noi's left hand, which looked like some kind of curse.

"It's what we call a side effect, and you've used it a few times before, right?"

Lu Cheng put his hand on Noi's shoulder and looked at her with a calm gaze.

Noi pursed her mouth and didn't answer, her right hand touched the scar on her left hand... Her left hand was trembling all the time during this time.

Lu Cheng could guess that this price was accompanied by a sharp pain.

She's scared... I was very scared.

"Miss Elena, don't use this kind of magic treatment with side effects, please trust the science at this time." Lu Cheng turned to Elena and said.

"Branch... Section... Learn? Elena pronounced the Chinese word again.

"The healer in my squad is already checking on the condition of your soldiers, and her healing methods are no worse than using magic."

Lu Cheng pointed to the pictorial not far away, which was already checking on the wounded soldiers while he was talking to Elena.

"Ten minutes have passed, can you step back a bit? I'm going to 'call' the food. ”

Lu Cheng diverted the princess's attention in this way.

"Time? I... Is it okay to stand here? ”

Elena had to choose a temporary compromise in the face of food, and hunger tortured her soldiers as much as injury.

Elena retreated a long distance, leaving plenty of room for Lucheng.

"No problem."

Lu Cheng used his meat bun summoning technique on the ground.

In less than a minute, under Elena's incredible gaze, a large bag of meat buns, white porridge and a small pot of eggs slowly emerged from the portal.
