Every hour, or half an hour, sometimes even a quarter of an hour, Zuo Zonghao would let out a loud shout, and at the same time, the spiritual power absorbed by the formation would suddenly increase several times.

After so many times, Liu Yu and Lu Daoyuan couldn't hold on a little anymore. Liu Yu's spirit wine had run out, and Lu Daoyuan's spirit wine had also taken a sip.

Although Chen Yu's face was pale, it was not yet time to use the spirit wine.

The spiritual power within Ishikawa's dantian has always remained above seventy, which is not unrelated to Ishikawa's "Tuna Decision" that he has practiced for several years. For many years, he has regarded "Tuna Decision" as his main practice, so that Ishikawa's spiritual power is long and full of stamina.

And Song Henian seems that the situation is not very bad, after all, he has been cultivating for decades, and it is understandable that he can have such a long spiritual power.

However, most of the five hundred spirit stones issued before have been consumed, and if you want to replenish your spiritual power, you will have to consume your own spirit stones.

Zuo Zonghao suddenly shouted, and the formation flag in the formation was fierce. The spiritual power poured out like a waterfall. Injected into the formation.

Liu Yu's face changed greatly, and he hurriedly took out a pill from the storage bag and took it, took out a few spirit stones, and hurriedly replenished his spiritual power. However, her spiritual power had long been exhausted, and the replenished spiritual power could not supply the needs of the formation at all.

"It seems to have failed. Ishikawa secretly said in his heart, for an ordinary eighth-layer cultivator in the Qi cultivation period, it was very rare to persist for five or six hours.

"I couldn't hold on. Liu Yu said weakly.

Before the words fell, Liu Yu suddenly exclaimed: "My true yuan, my true yuan is passing!"

True Yuan is the foundation of a monk, and decades of cultivation are for the trace of True Yuan stored in the dantian.

When the spiritual power is consumed, it can still be replenished, but the true yuan is a long-term penance, transforming the vitality of heaven and earth into its own pure and refined vitality.

Losing the true element means losing cultivation.

As soon as Liu Yu shouted like this, everyone's faces changed greatly. This is no joke.

In fact, everyone meant that the catalytic magic circle was going to fail this time, but they found that Liu Yu, who had exhausted the spiritual power at the earliest, was depleting the true yuan at an extremely fast speed.

For a while, a feeling of sadness for the dead fox and the rabbit surged into everyone's hearts.

But Zuo Zonghao was like taking a big tonic, and his clothes were puffed up by spiritual power.

His complexion became more and more ruddy, and the aura of spiritual power on his body became even stronger.

"Drink, drink, drink!" Zuo Zonghao shouted three times in a row.

Ishikawa only felt that his spiritual power was like a waterfall flooding, and he lost more than thirty percent in an instant.

Lu Daoyuan and Chen Yu directly picked up the small gourd and took a big sip. His face became more and more pale.

Ishikawa took out the spirit stone to replenish the spiritual power, and said in a loud voice: "Fellow Daoists, I don't think this person looks like a catalytic formation, but like he is using us to practice some kind of exercise. If this continues, after our spiritual power is completely lost, we can only be drained of the true yuan by him. ”

As soon as these words came out, the expressions of the four people changed greatly, in fact, everyone had similar doubts in their hearts, but they were still not sure, how could this evil method of absorbing the true essence of the monk appear in the dignified formation family, the Zuo family?

But it is true.

"Kawa Michiyu is right. However, we are now firmly controlled by the formation, and there is no good way to get out. Chen Yu said a little breathlessly.

And Lu Daoyuan, after drinking the last sip of spiritual wine, his spiritual power was completely exhausted, and he began to be extracted by Zuo Zonghao, and it was difficult to even speak.

"We can't delay any longer, we still have three monks at the eighth level of the Qi training period, and we still have the strength to fight against Zuo Zonghao at the tenth level of the Qi training period, if we drag it out any longer, and wait until one more person's spiritual power is exhausted, we won't have any advantage." Song Henian shouted: "Fellow Daoists, if you don't do it now, when will you stay?"

With that, a flying sword with red flames flew out of Song Henian's cuffs and stabbed towards Zuo Zonghao's body.

Ishikawa also took out the Zimu shuttle and attacked.

Zuo Zonghao was unaware, and he didn't release any magic weapons to resist at all.

At the moment when the Flame Flying Sword and the Mother Shuttle were about to touch Zuo Zonghao, the two magic weapons were suddenly bounced apart.

At the same time, the three of them were consumed a lot of spiritual power almost at the same time.

Three attacks in a row, all the same.

Chen Yu had to drink the spirit wine before he could barely hold on.

Ishikawa hurriedly said: "Two fellow Daoists, stop quickly, I feel that Zuo Zonghao is blessed by the formation, and our attack on Zuo Zonghao is nothing more than consuming our spiritual power." It seems that breaking this strange circle is the most important thing. ”

"Breaking the formation?" Chen Yu smiled bitterly and shook his head: "The Zuo family's formation, how can it be so easy to break, and this formation is so complicated, it is difficult to find the formation eye to break the formation." ”

Listening to Chen Yu's tone, it seemed that he had a feeling of resignation.

Ishikawa's mind raced to the treasures on his body that could help him get out.

The Golden Thunder Talisman is indeed a good thing, and with the power of the Golden Thunder Talisman, there should be no problem in breaking through this magic circle forcefully.

But there is not much spiritual power left on the true shield, and it is impossible to resist the blow of the Golden Thunder Fu. Moreover, this stone hall is not as luxurious as the Shuilingmen Mine Cave, it is all hollowed out of ordinary stones. In case the Jinlei Mansion blew up this stone hall, even if the formation was broken, it would be crushed into a meatloaf by this boulder weighing hundreds of thousands of catties.

After all, a cultivator in the Qi cultivation period has not yet had a physical body strong enough to be able to resist the strength of hundreds of thousands of catties.

"Fellow Daoists, use any treasures, even if you can't hurt him, you can't let him progress so smoothly. Song Henian shouted loudly.

A small silver fox jumped out of Song Henian's chest, this fox, with three tails, is a rare three-tailed fox, and was actually adopted as a spirit animal by Song Henian.

As soon as the three-tailed fox appeared, he rushed towards the formation without hesitation, wanting to destroy the formation.

As soon as he entered the formation, there was a lightning strike, which instantly hit the three-tailed fox's body, and the beautiful silver hair on his body instantly turned gray-black.

Lying on the ground without moving, if it weren't for the belly still lying down, it really made people think that the three-tailed fox was dead.

Ishikawa suddenly thought that there was a strange beast in his immortal mansion, and this strange beast should be interested in these array flags and other things, and if he could get the strange beast out, he should be able to destroy the magic circle.

However, Ishikawa doesn't know how to control beasts at all, and it is not a simple matter to get out of the beasts.

"Xianfu! by the way, Xianfu! I forgot about this. Ishikawa patted his head and said to himself.
