382 Oxygen Concentration

() Oxygen, nitrogen, carbon dioxide, inert gases...

As for the oxygen necessary for survival in the current crystallization cage, the current ratio in the crystallization cage has dropped to 17.8%. If it is based on the normal breathing of twenty people, it will take another three hours at most. Reduced to a dangerous level of 12.5%.

The reduced oxygen content will cause people to fall into drowsiness, and eventually die unknowingly in their sleep!

Raymond was horrified, facing the eye-catching three-hour countdown in his sight, he took a deep breath and then roared. "All gather, and the wizard apprentice stands next to Old Barney!"

They were taken aback by Raymond's roar, but everyone in the crystallization cage immediately began to gather, especially the ordinary people, who were afraid of being angered by the wizard in such an environment and causing accidents.

Facing Dorothea's and Old Barney's probing eyes, Raymond frowned and decided not to explain the reason, but began to question the three wizard apprentices. "Which of you knows the magic of the light system?" ..

He shook his head blankly, but the young third-level apprentice who released the flame spell just now had the courage to speak. "I, I know an improved version of the lighting technique. It is said that it is improved after combining the light system technique, which is much stronger than the general lighting technique!"

"Raymond, what level of light spells do you need?" Dorothea, who put little Staci's head on her shoulder and carried her in her arms, asked hesitantly. "I know several light spells, but the effects are different..."

"As long as it is a technique that can imitate the illumination of the light, I need to make the plants grow normally!" Facing the countdown that began to jump rapidly in his sight, Lei Meng didn't dare to delay any longer. "Ordinary people all lie down on the spot and start to rest, the three of you will use the lighting technique!"

Having said that, Lei Meng started to rummage through his waist pocket, and quickly took out the seeds bought in the "Old Wood" shop.

He took the three wizard apprentices to the corner of the crystallized cage, and followed Raymond's plant spawning technique. The plants that grew rapidly in his hands were quickly stimulated into mature bodies before Raymond threw them on the ground.

The luxuriant plants occupied one corner of the crystallized cage, and Lei Meng, who cast the lighting technique casually, placed the lighting technique at a height of ten meters.

Following the same process, the plants that were spawned began to spread along the walls of the crystallization cage, and the three wizard apprentices were also required to each be responsible for a certain distance of the plants, maintaining the range of their spell lighting.

Less than an hour. The oxygen concentration that was still slowly declining in the sight finally showed its effect. Ordinary people with poor physical fitness have already experienced slight shortness of breath.

But Dorothea and Old Barney, who had been by Raymond's side all the time, somewhat understood Raymond's intentions. Especially the light spell cast by Dorothea made the extremely nervous Raymond finally heave a sigh of relief.

A round of simulated red sun that does not have attack power. Although the brightness is not particularly high. However, after analyzing the spectrum of the chip, it was discovered that the radiation breath emitted by this technique is very similar to ordinary sunlight, and the slowly released ultraviolet rays are necessary for plant growth.

The seeds of most of the ornamental plants in the waist pocket were spawned by Raymond's magic. However, those plants with narrow leaves were directly destroyed by Raymond after they were spawned.

Because if you want to produce oxygen through photosynthesis in such an environment, you must have a large number of plants with thick leaves.

Lei Meng, who came down from a full circle around the crystallization cage, saw four spell lights appear above his head. As well as the round of red sun cast by Dorothea, the oxygen concentration observed by the chip in the line of sight finally showed a trend of slowing down.

The problem of light was solved, but the leaves of the photosynthetic plants under the influence of the magic spell soon became wilted and yellow, which reminded Lei Meng.

After taking out the compressed water test tube in the waist pouch, as the water continued to irrigate, the oxygen concentration had dropped to 16.2%, and finally no longer decreased but slowly increased.

"Hurry up and teach this method to other people in the crystallization cage," Raymond immediately explained to Dorothea and Old Barney without waiting for the oxygen concentration to rise to a normal level. "Also, if there is really no other way, we can only let everyone go to sleep, which can delay the time of suffocation death!"

The two people who quickly retrieved the spell interface immediately began to communicate with other people in the crystallization cage, and Lei Meng also quickly thought of the most important question, which was about the fire spell. .

After any fire-type spell is cast, although it consumes the wizard's mana to keep it waiting to be activated, these fire-type spells also need to consume a lot of oxygen.

It is the safest way to increase revenue and reduce expenditure.

But not long after Dorothea and old Barney sent the message, the crystallized cage on the right side of the prisoner Raymond and the others suddenly burst out with intense magic light, and within a full minute, In the crystallized cage over there, the faint light of the magic technique continued to flicker.

Lying in the corner of the crystallization cage, with the help of the adjustment of the lighting angle of the technique, Lei Meng could vaguely see that a battle broke out there, but soon there was no light in the crystallization cage, and the recovery was restored. calm.

With a sinking heart, Raymond knew that there must be something wrong, but when he turned around, he saw Dorothea with a pale face.

The color of her delicate face was gone, and there was a trace of horror in her blue eyes. "Moduo, Modo's breath of life has disappeared!"

"How do you know?" Raymond frowned, and immediately thought of a possibility, but he still guessed according to the best result. "Maybe he was disturbed by some kind of radiation, so hurry up and send him another message."

"Impossible!" There was a hint of sadness in her eyes, but Dorothea's tone was extremely firm. "Moduo's life mark will not be disturbed by any radiation aura. Even if he is in a large rune array, the aura given by the Modo family will be displayed immediately!"

Seeing that although Dorothea's expression was a little sad, it didn't look like the kind of sadness she would treat her relatives, Raymond hesitated and said what he thought of. "So if something really happens to Modo, will his family send people here to investigate?" (To be continued.)
