This beast-derived crystal is not ordinary, it is a hundred meters high, and it is a very huge crystal, about the same as a small hill.

It was also the first time for Lin Yi to see such a huge beast source crystal, and he was stunned.

After a long time, Lin Yi came to his senses, quickly opened the four space universes, and sucked in this animal source crystal.

After entering the universe, the beast origin crystals emitted a very powerful mysterious spiritual power, which spread continuously in the universe, and the spiritual energy skyrocketed.

Even the beauties who practiced in Lin Yi's universe felt the aura, and their cultivation speed increased a lot.

Yun Ji also felt it, and opened her eyes instantly from her training, "What a strong breath, Lin Yi, this seems to be the crystallization of an ancient source beast!"

Yun Ji was indeed very knowledgeable, she guessed it just by feeling this aura.

"Yes!" Lin Yi replied immediately, "I was lucky, I met two ancient source beasts fighting, and I got a bargain!"

"So that's it!" Yunji smiled lightly, "This beast origin crystal is very powerful, and it is also very useful for our cultivation!"

Lin Yi directly threw this beast source crystal near Yun Ji, without devouring it at all, the aura emitted by this beast source crystal alone could greatly increase their cultivation speed.

And Lin Yi's universe is also slowly melting and devouring this crystal, and the improvement of Lin Yi's universe is also subtle, and the benefits will soon be highlighted.

After getting the beast source crystal, Lin Yi quickly left the foul-smelling belly of the snake and flew towards the mine.

On the way, Lin Yi met Ouyang Hai, Wang Chong and others.

"Lin Yi! It's Lin Yi!"

"Lin Yi is fine, great!"

"Lin Yi is back!"

Everyone laughed in surprise, and they were finally relieved to see that Lin Yi was fine.

"Lin Yi, you're finally back!" Ouyang Hai also laughed excitedly, "I thought you..."

Ouyang Hai shook his head, and asked, "How are the masters in Thunder Fire City?"

"Dead!" Lin Yi replied bluntly, "Eat by an origin beast!"

Everyone couldn't help but gasped, "Could it be that big white boa constrictor?"

Lin Yi nodded, "Yes, that should be an ancient source beast, a snow python!"

Ouyang Hai nodded solemnly, "We all saw it just now, and we wanted to catch up to help you, but in the end we encountered two terrifying Origin Beasts fighting, we have no choice but to stop!"

Wang Chong stared, still not recovering, and said, "Those two Origin Beasts are too terrifying. I'm afraid that even if they are experts in the Consummation Realm, they are just ants in front of them!"

"As Lin Yi said, that is the legendary ancient source beast!" Ouyang Hai nodded, "Our innate realm is indeed just an ant in front of the ancient source beast, and only the Vientiane realm can be compared with the ancient source beast." Origin beasts to contend!"

As he said that, Ouyang Hai smiled slightly, and looked at Lin Yi, "Lin Yi, you are not injured, what a blessing!"

Lin Yi shrugged, "When they fight, I hide far away, otherwise I would have died a long time ago!"

"Let's go back to the mine!" Ouyang Hai didn't ask any more questions, and immediately led everyone back to the mine.

The mine at this time was already in pieces. After today's battle, more than half of it was destroyed, and even some Xuanyuan crystals in the crystal mine were destroyed, which is a pity.

What is even more distressing is that in today's battle, Haotianmen lost fifty or sixty disciples, all of them turned into cold corpses.

Obviously, if Lin Yi hadn't lured away all the people in Leihuocheng, the casualties would have been even more terrifying today, and it is not impossible for the entire army to be wiped out.

The most troublesome thing is that today is just a trial by Leihuocheng. If Leihuocheng attacks again, there will definitely be more masters and stronger strength, and it is impossible for them to block it.

It was getting dark, Ouyang Hai gathered all the disciples in the room, and continued to discuss the countermeasures.

Everyone is more depressed than the other. After today's battle, they have seen the huge gap with Thunderfire City. They barely survived today, but tomorrow and the day after tomorrow, Thunderfire City will come fiercely. It should be very soon to win this mine When the time comes, they will soon become a cold corpse.

"Lin Yi, what do you think?" Ouyang Hai proposed a defensive formation and looked at Lin Yi.

Everyone's eyes were also on Lin Yi, full of faint expectations.

If there is still a miracle to happen, it must be in Lin Yi's body.

Lin Yi's face was also very serious. He thought for a while before saying: "My opinion is very simple. If there are green hills left, I'm not afraid that there will be no firewood!"

Everyone was taken aback, not knowing what Lin Yi meant, Ouyang Hai frowned slightly, "Lin Yi, what do you mean..."

"No matter what defense we do, no matter how clever our formation is, it's impossible to block Leihuo City!" Lin Yi shook his head helplessly, "I've checked Leihuocheng's base before, and their strength is too strong. The attack must be 100% sure, we will be wiped out and occupy the crystal mine!"

Hearing what Lin Yi said, the disciples became even more depressed.

"So, instead of sitting still and being besieged by them, why don't we just retreat and give up this crystal mine!" Lin Yi said lightly.

"What?"

"Shall we surrender?"

"Could it be, admit defeat to those guys from Thunder Fire City?"

All the disciples became suspicious, and stared at Lin Yi with a little anger.

Ouyang Hai waved his hand and stopped everyone from talking, "Lin Yi, keep talking!"

"As I said, there is no fear of no firewood to keep the green hills," Lin Yi continued, "Even if Leihuo City occupies this crystal mine, or even all the crystal mines on the withered plain, it is impossible for them to burn it in a short time. , we will finish mining the crystal ore, so we will retreat first and meet with the support of Haotianmen, and when we are sure, we will fight back!"

Everyone fell silent for a moment, obviously everyone knew that Lin Yi's method was the most realistic.

However, this will obviously be very aggrieved, fleeing without a fight, without face!

"So, my suggestion is very simple, everyone evacuates quickly, temporarily abandons the crystal mine, and then regains it when we are sure!" Lin Yi said indifferently, obviously already sure, "At that time, it will not only take back this one The crystal mines are gone, maybe we can take back all the crystal mines, and even drive out the forces of Thunderfire City to occupy more crystal mines!"

Everyone's eyes lit up and they nodded.

Ouyang Hai was silent for a while, and said: "The support from the sect should arrive in three to five days. If we want to defend this crystal mine, can we hold on for three to five days?"
