When Qian Hong realized that he had the Pearl of Wisdom, the demon hunters had already sealed the entrance to the cave.

The rubble was used to block a wall, and the ink painting was used to draw formations on the wall. Then the rubble was used to block a wall, and the ink painting was painted again. Then a wall was blocked, and the ink painting was painted again.

There are three walls inside and outside, and three sets of formations.

Mo Hua asked for hundreds of spiritual stones from Elder Yu, crushed them and injected the spiritual power into the formation to activate the civil formation.

The earthy gray and light green lines on the formation are intertwined, and spiritual power seeps into the gravel, mixing the earth and stone together to form a hard barrier.

"Can this formation be defended?" Elder Yu was still a little worried.

Mo Hua felt that there was no problem in his heart.

The Earth Fire Formation uses paper as the formation medium and can only be used once. However, today's Civil Engineering Complex Formation uses earth and stone as the formation medium, which is durable and requires a lot of time and effort to break the formation.

And after all, it is a first-level restoration formation, which should be enough to deal with Qi Refining monks - if Qian Hong and Qian Zhongxuan do not take action during the foundation building stage.

But it’s hard to make a conclusion without trying it.

So Mo Hua could only vaguely say: "It should work."

Now that the matter has come to this, Elder Yu did not hesitate and ordered all the monks to concentrate on digging the mining tunnel, and the remaining spiritual stones were not mined.

Be sure to dig out the escape tunnel before the Qian family breaks through the mine.

The movement of the demon hunter was also noticed by the Qian family.

Qian Hong sneered and said: "As expected, Yu Changlin sealed the entrance of the cave and was digging the tunnel."

After saying this, he ordered the monks from the Qian family to investigate. After the monks from the Qian family made inquiries, they reported back to Qian Hong, saying that the entrance to the cave was sealed by a wall made of earth and stone.

Qian Hong didn't care. Even if some walls made of dust and gravel blocked the entrance, they would be broken in less than two days.

But the monk from the Qian family struggled at the entrance of the cave for a long time, then turned back and said:

"Report to the head of the family, he can't be beaten."

Qian Hong frowned, "What can't be beaten?"

The disciple lowered his head and said: "The entrance to the cave is blocked by earth and rocks, we can't break it..."

Qian Hong frowned even more tightly.

Qian Zhongxuan was slightly startled when he heard this. He had some guesses in his heart, and a gloating smile appeared on his lips.

Qian Hong said: "Let me go and take a look."

Qian Hong came to the entrance of the cave sealed by earth and rocks, and naturally noticed the formation fluctuations on the earth and rocks.

Is there... a formation drawn on it?

Qian Hong felt something was wrong and ordered: "You guys try to hit me."

Several monks from the Qian family came forward, some with knives, some with swords, some with bare hands, and some with magic.

Although it was possible to cut through the gravel and open some gaps, the gravel soon came together again as if it were alive.

It seems that these stones are like earth and wood, growing together and repairing themselves.

The monk from the Qian family gave it another crackling blow, panting from exhaustion, but with little effect.

Qian Hong couldn't help it anymore, he drew out his sword and struck him with one strike.

This sword used the cultivation of the Foundation Establishment Stage, and its spiritual power was like solid matter. The sword energy cut away a layer of gravel.

Qian Hong was horrified, "First-grade formation?"

Did Qian Zhongxuan tell a lie? There is really someone among the demon hunters who can draw a first-grade formation!

Qian Zhongxuan saw Qian Hong's surprised look and felt very happy in his heart.

"The formation of seven formations is nothing more than this in the final analysis. I believe that the head of the family will be able to break this formation soon and kill all these demon hunters in one fell swoop!"

On the surface, Qian Zhongxuan still looked serious, but his tone was somewhat sinister.

Qian Hong's face remained calm, and he was slightly angry, but could not refute.

The formation master in Demon Hunter is just an ordinary formation master who can draw seven formation patterns.

He said this himself. If he denies it, he would be slapping himself in the face.

He could only accept Qian Zhongxuan's sarcasm at this time and settle accounts with him in the future.

The most thorny problem at hand is how to break through the cave entrance, break into the mine, kill these demon hunters, seize the spirit stones, and occupy the spirit mine.

Qian Hong was about to take action himself, when suddenly Elder Yu's voice came from above:

"We agreed not to take action during the foundation building period, so don't be shameless."

Qian Hong looked up and saw Elder Yu looking at them mockingly in front of the only unsealed cave entrance on the mountainside.

Qian Hong sneered, "You don't have to take action against the monks, but I didn't say you can't take action against the rocks."

Elder Yu half-smiled, "Then you go ahead, I'm here to watch you."

Qian Hong frowned, but did not dare to take action.

If he breaks through the hole, consumes too much spiritual power, and is attacked by Yu Changlin, he may not be able to defeat him.

When the matter was brought to Dao Tingsi, Yu Changlin could argue that it was the Qian family's foundation-building monks who made the move first.

The Qian family's foundation-building monks took action to break the demon hunter's formation, and it can indeed be regarded as the Qian family's first move.

What's more, there was Qian Zhongxuan next to him. If he took action himself, he might get an advantage.

After Qian Hong hesitated, he stopped.

"Okay, I will follow the agreement and only let the Qi Refining monks take action."

Yu Changlin breathed a sigh of relief, but in his heart he looked down on Qian Hong more and more:

"Then don't occupy the latrine without shit, get out of here earlier, move to another position, and let your little bastards in the Qi refining stage come over and see if they can break this mine."

Qian Hong gave Elder Yu a sinister look and waved his hand.

The monks from the Qian family stepped forward one after another, using swords, martial arts, Taoism, or spells to attack the earth and rocks at the entrance of the cave one by one.

When one monk is exhausted, he is replaced by another.

As for the entrance of the cave where Yu Changlin appeared, it was impossible for them to get in if only one man guarded the entrance and no one could open it.

Only by opening a few more holes, advancing together, and allowing a large group of monks to attack can we defeat these monster hunters.

Although the defense of the first-grade civil formation is strong, it also relies on the spiritual power of spirit stones to support the effectiveness of the formation.

Each time it is damaged, one point of spiritual power will be lost.

The monks of the Qian family continued to attack day and night for several days, and finally succeeded in breaking through a civil defense formation.

With the rumbling sound, the first earth and stone wall lost the support of the formation and collapsed into rubble.

The Qian family monks were all in high spirits and looked happy.

But they were not happy for long before they realized something was wrong. Because behind the stone wall, there was still a stone wall.

They tried to chop it with a knife, but the earth and stone on the wall did not move at all. It was obvious that there were also formations painted on it.

The monks from the Qian family looked desperate, and Qian Hong's eyelids twitched.

He never expected that Yu Changlin would be so ruthless and create two stone walls and two formations.

No, there can’t be more than two...

Qian Hong gritted his teeth and asked the Qian monks to stop repairing and continue to fight after resting.

At this point, there is no turning back for him.

When the Qian family started digging the mine, Elder Yu was inside and listened. As he listened, he found that the Qian family suddenly stopped moving again, and he couldn't help but wonder:

"Why don't you fight?"

"I can't fight anymore."

After these few days, Mo Hua finally confirmed the effectiveness of the first-grade earth and wood formation. For Qi Refining monks, this formation is difficult to break.

What's more, the ink painting is coated with three layers.

Elder Yu still didn't understand, "Why can't you fight?"

"This is a first-grade complex formation. After breaking through three levels, they will be exhausted to death!"

"Falling back?" Elder Yu had never heard of it and was a little confused.

"It is a formation that is even more powerful than the first-grade formation." Mo Hua explained.

Elder Yu's eyes widened. Is it more powerful than the first-level formation?

Then he said: "Then this formation can be defended for a long time?"

Mo Hua made an estimate and nodded. If the foundation-building monks don't take action, they can indeed defend it for a long, long time.

If there is no shortage of food and drink.

Elder Yu was stunned, and then felt deeply regretful.

If he had known that Mo Hua's formation was so easy to use, he wouldn't have been in a hurry to dig the mine.

There are still many spiritual minerals that have not been mined in this mine...

Those are all spirit stones!

Elder Yu, who has always been diligent and thrifty, looked pained.

Mo Hua saw Elder Yu's thoughts, thought about it, his eyes lit up and he said:

"Why don't we do something extreme? We won't even give them any soup!"

These words struck Elder Yu's heart. He thought for a moment and nodded, "Indeed, waste will be punished by God!"
