There is no oxygen in the claustrophobic space. The only remaining oxygen has been consumed by Ye Qingfeng and others. The remaining air components are no longer enough to support people's breathing.

Wumeng guessed it well. It was flooded with ice stones. Not only could it not breathe, but it was also extremely cold. The ice water dripped down and wet everyone's clothes.

Without mana, they cannot live for a quarter of an hour here.

But everyone's magic power is limited. With such constant consumption, it is impossible to connect with the spiritual energy of heaven and earth to form a benign cycle of reincarnation, which will not last long.

When he knew that the spiritual energy of heaven and earth had been cut off, Ye Qingfeng and others' hearts sank.

Mu Zibai murmured: "It's been eight hours."

Ye Qingfeng said: "What eight hours have passed?"

Mu Zibai said slowly: "Eight hours have passed on the hidden runes on our bodies."

Hua Jieyu's face changed and she couldn't help but say, "I remember you said that hidden runes can only last twelve hours, so wouldn't there be only four hours left?"

"good."

Mu Zibai said: "This means we will be discovered after four hours, and it will take about two hours to engrave the runes. In addition, Wuwei and others have been patrolling. I dare not use this big fluctuating magic power when I get too close. This will delay the engraving time of my runes."

Ye Qingfeng said in a deep voice: "I understand, it means that if you don't make runes immediately now, it will be too late."

Mu Zibai nodded and said, "But my mana is only 40% left, and I need someone to replenish my mana."

Bai Wuyou said: "Brother Qingfeng and I will replenish you 30% each, and we still have a lot of magic power left."

"not much."

Ling Shuangyue said directly: "The mana of Qingfeng is only 60% left at most, while you are only 40%."

"That's it, don't lie to us."

Xue Qianxun said: "I have the most left, and I have about 80% left."

Jiang Shuxue also said: "I'm 80% too."

Xue Qianxun smiled and said, "Sister Hua and Sister Shuangyue have used a lot of mana just now, so there shouldn't be much left now. Sister Shuxue, let us share 30% of it and let Mu Shitou carve the runes."

"not enough."

Mu Zibai raised his head and said slowly: "If it were you, you would need to contribute at least 120% of your magic power, and there is a gap in our realm."

Everyone was also stunned, and then they remembered that Mu Zibai was the demon king. His magic power was deeper than those present except Ye Qingfeng. Then 10% of him was equivalent to twice the number of everyone."

Ye Qingfeng said: "Stop talking, I will pay 30% of the remaining 30%. You must pay 60% of the price. You two can make up for it."

Mu Zibai also said: "It's settled, let's start."

So the difficult rune engraving began. As Wusong and others patrolled back and forth on the top, Mu Zibai did not dare to engrave it at any time. In addition, there was not much magic power left in his body, and at the same time he had to accept the power from everyone, so his speed was even slower.

What I am even more afraid of is that if you accidentally find out by someone above, things will be even more difficult to deal with.

But time was only four hours, and he had to carve a full seven runes.

Such urgent time, such great risks, fear and claustrophobia coexist, tension and danger coexist.

Everyone's faces were covered in sweat, and they were so nervous that they couldn't speak.

After Ye Qingfeng sent mana to Mu Zibai, he gritted his teeth and leaned against the cold stone wall, closing his eyes and buzzing in his mind.

His hands were numb and held by the colder hands. Ye Qingfeng could feel the delicateness and care.

He slowly opened his eyes, but could not see Ling Shuangyue's face. It was too dark here and no one was willing to waste his magic power to increase his eyesight.

Although Ye Qingfeng couldn't see it, he could imagine that Ling Shuangyue's face must be very bright. The brightness is confidence, hope, believing in the strength of this world, and the best yearning for the future.

Both of them were extremely cold, but they held each other tightly, and seemed to be unwilling to let go for a moment.

"We can survive, we must."

This sentence was said by Ye Qingfeng. Every time he was desperate, Ling Shuangyue gave him strength. This time he wanted to give Ling Shuangyue the strength.

"Um..."

A gentle whisper warmed to the bones, and the hearts of the two of them were instantly connected.

Silent, silent, and not even a low breath.

It is so quiet, so quiet that it is so desperate.

The time is too long, so long that it makes people want to go crazy, but four hours have passed after all.

Mu Zibai's rune finally posted on everyone before the previous rune expired.

These seven runes consumed too much mana, but they were exchanged for twelve hours of safety.

"what to do?"

Xue Qianxun's voice trembled a little. She has matured a lot over the years. She no longer fears or panics when encountering things, but this time it was a desperate situation, a real desperate situation.

Everyone did not answer, including the two think tanks, Mu Zibai and Ling Shuangyue, because they were also thinking about what to do.

"How long can our mana last?"

Bai Wuyou asked this question, but this question is no longer a problem, because everyone knows that they can only last for twelve hours.

Ye Qingfeng said: "If we just stay like this, our mana is enough to keep here for a month. After all, we are considered strong people, but... but after twelve hours, we need a brand new hidden rune that can deceive the hidden rune of strong people of the faceless level. We don't have the magic power to support the engraving of hidden runes."

Twelve hours seem long, but they seem to be very short. Now everyone is no longer so sensitive to the flow rate of time.

There was silence in the field, as if it was dead, and this silence was enough to ruin a person's heart.

Ye Qingfeng said in a cold voice: "Enough! Don't act like you want a dead dog. We will cheer up. Twelve hours are not short. We can find a way. The birth of wisdom only takes a moment."

His voice became louder, which shocked everyone.

Ling Shuangyue said softly: "Yes, everyone, we still have twelve hours to find a way. We still have a chance to survive, don't give up."

Lao Bai said: "I am very confident to survive, but I really can't think of any bullshit. If I were asked to find a way, then the solution was to stop worrying about so many things and rush out and work with them. It would be better to suffocate to death here than to suffocate them."

Hua Jieyu said: "I always feel that we have overlooked something, but I can't remember it for a while."

Mu Zibai also immediately said: "I also have this feeling. It seems that there is something I should have thought of, but because of my condition, I didn't think of it."

"Then let's sort it out."

Ling Shuangyue smiled and said, "We have only three possibilities to survive. First, we rushed out, defeated Wuwei and others, and left directly. Second, we found other ways and quietly walked out from here. Third, we stayed here, waiting for rescue, but we needed mana supplies to support it."

"At present, the first one cannot be realized, the second one cannot be realized, and only the third one is in line with our current situation."

She raised her head and said, "But how can we find the supply of mana?"

So in the end, the reasoning came back to this fatal question. How could it be possible to restore magic power when the spiritual energy of heaven and earth is blocked? This is a dead knot.

The field was uncontrollable and fell into silence again, quietly swallowing everything, allowing everyone to clearly hear their heartbeat and clearly feel the cold around them.

"Big Boy, will we really die?"

Xue Qianxun's voice was very light and confusing.

Bai Wuyou grinned and said, "Don't worry, our lives are so hard that we will definitely not die."

Xue Qianxun whispered: "But everyone has no choice. Mu Shitou is the best, but now he has no choice."

Bai Wuyou said, "Isn't that still me? I will take you out after twelve hours. I don't believe that Faceless can kill us all."

"No...no."

Xue Qianxun quickly grabbed his arm and shook his head and said, "Do you want to lead them away and let me go? No, I won't leave you. That time, my heart broke once. I dare not have that feeling anymore, otherwise I wouldn't be able to hold on."

She leaned her head into Bai Wuyou's arms and said softly: "Don't die. Actually, I have lived a wonderful life over the years. Master loves me, uncles spoil me, senior brothers, senior sisters and sisters all like me, and be nice to me, and you are kind to me, I think it's worth it."

Bai Wuyou couldn't help but smile and said, "Hey, you have a little conscience, you know that I am good to you."

Xue Qianxun said: "But I still don't want to die. I think I have regrets."

"What regret?"

Xue Qianxun whispered: "I haven't had time to repay you for your kindness to me yet, I can't bear to die."

Bai Wuyou's fists were clenched, and his bones slammed. He slowly said, "Don't worry, we won't die so easily."

"Um!"

Xue Qianxun said: "Master should save me. He loves me the most. He stands up for me and makes decisions for me if I suffer any grievances. This time I was buried below. Master will definitely come. When he gets angry, he will not care about anything."

"Well, believe him."

Bai Wuyou closed his eyes and still clenched his fists.

On the other side, Ling Shuangyue and Ye Qingfeng leaned side by side on the cold rock wall, and their hands were tightly pulled.

Ling Shuangyue whispered: "If this time..."

"No if."

Ye Qingfeng interrupted directly: "I know what you want to say, what if we die this time, right?"

Ling Shuangyue said: "Will you regret walking on this road? This road is so bumpy and so difficult."

"Won't."

Ye Qingfeng said: "I won't even consider regretting this issue. I am a disciple of Tiance Mansion, I am a soldier, and my duty is to defend the mountains and rivers. Besides, I am the son of a knight, and I have my soul."
