Although the guards are all in the Yuan Realm, although the soil outside the formation is relatively soft. However, digging 30 zhang deep is by no means a simple and quick thing.

If you dig a horizontal cave and dig into it for 30 zhang, you only need to be more than 30 zhang wide and high.

However, to dig a hole directly into the depth, and to dig 30 zhang deep, it is necessary to dig a hole with a diameter of 5 or 6 zhang. And the eight guards digging at the same time, there must be more space, thirty zhang deep to transport soil outward, it is also not an easy task.

Of course, the advantage of digging this time is the advantage of the number of guards, and the eight people who are responsible for digging a cave can speed up the efficiency of digging. After all, everyone in the Earth Yuan Realm, with the help of storage and soil transportation, once again made the efficiency faster.

Most of the day passed, and each group of eight guards cooperated to dig a cave with a diameter of eight zhang and a depth of thirty zhang on all sides.

Wu Feng was in the cave, his fellow cultivators of the Five Spirit Exercises, the Five Spirit Elements were also affinity, and he immediately noticed that in the cave, the water spirit elements were quite dense, and they could be far better than the special secret realm treasure land.

"Could it be that at a depth of thirty zhang, the connected spirit veins have been dug up, if the spirit veins are dug out and the circulation of the spirit elements is blocked, and there is no spirit element to supply the wordless tablet, I think it will be easy to eliminate the formation!" Wu Feng secretly guessed, although he had not learned the formation skills, but the most basic situation, he also knew a little.

After all, the old man of the formation mage once said that this formation is special, and it basically relies on the terrain on all sides, and the wordless monument can be eliminated by directly destroying the wordless monument. And the reality of the terrain on all sides, the spiritual veins that flow are convenient, and now that the spiritual veins are dug out, it is difficult for the spiritual elements to keep flowing.

All the guards wanted to make meritorious contributions, and compared the speed of digging with the other three groups, when the group of Wu Feng dug as required, the remaining three groups basically dug at the same time.

When everyone returned to Yi Chengtian and reported that it had been done as required, there was no obvious change on the surface of the formation. Yi Chengtian immediately spoke up and asked the old man of the formation mage, "Now that the cave has been dug out, why hasn't the formation been eliminated yet?"

"Hmph! Just digging up the spiritual vein, I want the formation to be automatically eliminated, and now you attack the wordless tablet again, and the wordless tablet will be broken. The formation will be eliminated, and the entrance you want to explore should be at the place where there is no word monument!"

It can be seen that during the waiting time, Yi Chengtian and the old man of the array mage could not reconcile at all. Yi Chengtian, as one of the top ten sons of the Yi family, is relatively strong in his own right, and the old man of the formation mage is a dignified fourth-level formation mage. must hold on to their own pride, and this will inevitably create a gap, which has nothing to do with external instigation.

And from the gap itself, the possibility of harmony is very small.

Of course, Yi Chengtian and the old man of the formation mage were only verbally arguing, even if they were angry in their hearts, there was no direct conflict. There is no possibility of war.

Moreover, the appearance of the old man of the formation mage. I seem to be curious about things in the team.,There's no idea of leaving directly at all.。

"Boom! Click......" Yi Chengtian heard this, so he took out his sword again, tentatively attacking the wordless tablet, the impact of the leakage of the first spirit yuan, and then the direct stab of the spirit sword.

Needless to say. The sound of this attack was different from the previous one, causing the wordless tablet to fluctuate slightly, and the tip of the sword pierced straight at the point, revealing a half-inch gap two fingers wide.

"Okay!" Yi Chengtian was immediately overjoyed. Turning to the three mid-Earth Yuan guards, he made a statement and arranged: "You guys who carry crossbow carts with you, quickly set them up, and give me a fierce bombardment!"

The Blue Dragon Clan, since it can be called a clan, is by no means simply a team of thirty, so there is no rest to rely on in battle. For example, in the case of ranged attacks, the crossbow arrows equipped with the chariot are more agile than the crossbow arrows of the treasure ship, and the ground attack is more stable, and the chance of hitting is higher.

The three captains did not dare to hesitate, quickly took out the crossbow arrows of the chariot, selected the appropriate attack position, assembled the crossbow arrows, and prepared to shoot at the wordless monument.

Needless to say, Yi Chengtian's attack, although it showed an attack effect, also detected the wordless stele, it was difficult to break it directly, even if the spirit vein had been dug out, but the earlier spirit element attack had not dissipated so quickly.

Relying on the chariot crossbow arrows and attaching the impact of the violent sigil, such an attack is most appropriate. And the old man of the formation mage also didn't say anything this time, full of expectations for this attack.

"Boom!"

The crossbow arrows of the three chariots of the "Boom ......" all hit the wordless monument, causing the fragments of the wordless monument to slowly fall out from the periphery, and because of the loss of the support of the formation, it was directly like dust to dissipate.

During the continuous attacks of the "Boom ......", the carving of the bull's head without a wordless monument has been extremely dilapidated, and most of the bull's head fell at one time.

"Boom!" This time, the bull's head carving fell completely, and the wordless monument directly collapsed.

"Boom, boom, boom......" half-zhang high wordless monument was extremely bright earlier, exuding a peculiar luster, and it was not damaged by time at all. However, now that the formation has been eliminated, the material of the wordless tablet has not been refined, and the first lump that fell off has slowly turned into dust.

The wordless monument carved with the head of the ox ...... "Boom, boom" has been completely scattered like dust, but suddenly it resounds.

"What's going on?" while waiting for the formation to be eliminated, such a thought appeared in the hearts of everyone on the spot, after all, the dissipation of the wordless monument had completely shocked people's hearts, and they all maintained a high level of vigilance against the slightest unknown sound.

The sound of "boom ......" continued, and it became more intense, and the ground where he stood shook slightly.

"Retreat and disperse, wait and see what happens, and ensure your own safety!" Yi Chengtian immediately ordered, even if he knew that there was no word tablet and the relevant spiritual veins and spiritual objects, no one could know the exact situation of the uniqueness of this formation.

After all, according to the exploration of the old man of the formation mage, if the wordless tablet seals the spiritual vein of the town, now that the spiritual vein has been dug up and the formation has been eliminated, it should be dug to the intersection of the spiritual veins, so as to directly dig out the spiritual object.

Moreover, Yi Chengtian's treasure map of ancient monuments only points to the wordless tablet carved with the head of the bull, which is related to the simple intention of building a formation, and is slightly related to spiritual objects, which is also inaccurate.

Therefore, such a situation is still unknown, Yi Chengtian ordered to retreat, when it can ensure safety, it can be a wise arrangement.

"This kind of sound is like opening up a secret passage somewhere, not simply eliminating the formation!" Wu Feng secretly guessed, and he also didn't know the exact situation.

"Boom!" This kind of sound lasted for five or six breaths, and finally it was not heard again, and with the shaking of the ground, a hole with a diameter of three zhang was already shown at the place where the wordless monument was erected earlier.

"Huh, secret way!" Wu Feng was slightly surprised in his heart, not thinking that his earlier guess was really related to the actual situation.

"Huh......" Yi Chengtian was also surprised, and more full of anticipation, and the excitement of about to obtain the treasure, he immediately controlled his mood and ordered: "Everyone is ready, explore this secret path at any time!"

"Steady, steady! You must maintain normalcy, and don't make the slightest mistake before you see the spiritual object!" Wu Feng was also full of expectations, and secretly warned himself in his heart.

In fact, there is no need to say Yi Chengtian's excitement, there is no need to say Wu Feng's expectations, when the secret passage cave is revealed, the water spirit element that leaks out has already proved that the spiritual objects in it must be quite advanced.

Of course, whether there can be a top-level spiritual artifact or not, it is not possible to accurately detect it at present.

"Childe, there is no way to explore the specific depth of the hole, it is recommended to put a rope to investigate, Childe will wait with peace of mind first, and we will explore the way for Childe!" The first captain went to the entrance of the cave, detected the general situation, and then reported to Yi Chengtian.

"Since you need to put the ropes, tie the three chariots steadily, the third team will be responsible for guarding duties, and this son and the first and second teams will enter the secret passage at the same time to investigate!" Yi Chengtian arranged, it was not that he couldn't believe the guards, but because of the excitement and expectation in his heart, he wanted to see the spiritual objects recorded in the treasure map earlier.

Yi Chengtian made arrangements, and the rest of the guards naturally had no opinion, the first captain's statement earlier was only suggested because of safety, and now that Gongzi is entering at the same time, everyone must be cautious and do their best to ensure Gongzi's safety.

Of course, the rest of the guards were loyal, but Wu Feng was not a guard, and when he heard that Yi Chengtian had arranged it and guarded outside the third guard, he suddenly breathed a deep sigh of relief, and he was really worried that he would not be able to snatch the spiritual object immediately.

However, Wu Feng was a little worried, the old man of the array mage, he was also ready to enter the secret path to explore, if he really wanted to snatch the spiritual object, this old man's obstacle was huge.

The guards quickly arranged, put the ropes into the hole, the first team led the way, Yi Chengtian and the old man of the formation mage entered together, and the second guard team guarded with them.

The cave is indeed extremely deep, only three zhang in diameter, and it is more than 100 zhang deep, about 100 zhang in appearance, the first team to explore the road landed first, and Wu Feng was in it.

"The secret room of the cave passage, how can it be so big?" The situation found out on the ground immediately shocked Wu Feng, and the rest of the guards were equally surprised.

"Everyone disperse to investigate, check the dangers around you, try to eliminate the dangers, and mark and warn the dangers that cannot be eliminated!" The first captain arranged, such a secret room exploration, the most worrying thing is nothing more than the mechanism, and the investigation of the mechanism, you must be extra careful.

Wu Feng did not disperse, directly to the front, a three-zhang high tablet, his soul scanned the secret room, known that this more than 100 zhang diameter, circular inside the secret room, this monument is the center, when the key in the secret room, and has not yet seen the spiritual object.

"Refining the poison of the dragon's cave, condensing the spirit yuan crystal!" The tablet of three zhang is decent, and the big characters in the highest position are engraved with these two sentences.

"Yu came with the sect to kill the poisonous Jiao that plagued the swamp, and on the way back to the sect alone, he noticed that the terrain was peculiar, and the four spiritual veins converged in the central waterhole, and the spiritual veins contained a trace of poisonous dragon blood, which could breed snakes to the poisonous Jiao ......"

"Lest the scourge of regenerating poisonous Jiao, Yu established a formation to transfer the spirit vein of the dragon's lair, transferred the spirit vein toxin to the waterhole of the poisonous Jiao's lair, and separated the water dragon spirituality of the spirit vein, condensing the pure dragon blood water spirit crystal......"

"Dragon blood water spirit crystal, it turned out to be a dragon blood water spirit crystal, if it has been bred, it must be a top-level spiritual object, and a top-level dragon blood water spirit crystal is even more of the best legendary spiritual object among the top water spirit objects!" When reading the previous secret record, Wu Feng was still relatively indifferent, and then he knew about the spiritual object that was conceived, and Wu Feng's heart was full of shock.

"Dragon Blood Water Spirit Crystal, I must take it!" The thought in Wu Feng's heart suddenly became more resolute. (To be continued......)
