"Boom—"

In the blink of an eye, the thunderclouds were accumulated, and Lu Nan waved the thunder sword in his hand forward, and the Dao Dao thunder light slashed under the construction site.

The thunder light split the formations of the ancient formation, and coincidentally, these formations were also a few open places carved out of the construction site.

If the building has already been built, it will be very difficult to deal with.

The thunder slashed at the formation, and it didn't have much effect other than blasting the dirt apart.

These formations were not affected at all, and the faint aura emitted by them did not speed up the emanation because of this, which in turn proved that this wave of Lu Nan's mine-guiding attacks was useless.

It seems that the strongest means are still needed!

"Nine Heavens Thunder Divine Sword True Technique!"

Lu Nan held the Tiancong Cloud Sword, led it to the sky, and recited a mantra in his mouth.

"All souls return to you, all qi return to you, the sky has to be clear, the earth has to be a peace, the gods have a spirit, all things have to be born, the power of the thunder of the brilliant sky, the thunder general, the thunder soldier, the thunder drum, the thunder essence, the heavenly general, the heavenly soldier, the heavenly drum, the flying gold essence, the fire wheel, the cloth Xun Qi, the goblin, the moaning, the five thunders are fast!"

"Edict!"

The Nine Heavens Thunder Divine Sword True Technique Lu Nan had already used it perfectly, and as he finished reciting the mantra, the Heavenly Cloud Sword in his hand was drawn to the formation point.

In an instant, the divine thunder formed by the color thunder and lightning rushed towards the formation above the ancient formation.

"Boom, boom—"

This time, the sound effect produced by the Divine Thunder Impact Formation was several times greater, and the destructive effect on the formation was also several times greater.

"Sneer—"

Three formations were even directly broken by the divine thunder, and then the obscure aura that emerged from the ancient formation became even stronger.

Lu Nan saw that the true trick of the Nine Heavens Imperial Thunder Divine Sword had an effect, and immediately came again, and the divine thunder once again destroyed four of the formations above the ancient formation.

Maybe this time the formation belonged to the beam and pillar type in the ancient formation, Lu Nan felt that this formation was broken by seventy percent in an instant, and the obscure qi inside suddenly bubbled out like a rushing river.

The faint aura that had now accumulated under the golden light shield of the Concentration Spell had formed layers of thick dark clouds.

"Heaven and Earth Qingming Fu!"

Lu Nan is like planting a grain of millet in spring and harvesting 10,000 seeds in autumn, and he began to harvest with the Heaven and Earth Qingming Fu.

"Heaven and earth are infinite, Qiankun borrows the law, and is as urgent as the law, edict!"

As a handful of Heaven and Earth Qingming Talismans were scattered, the Yin Virtue points on the personal attribute panel rose gradually.

"Congratulations to the host for clearing the obscure aura and gaining 100 Yin Virtue!"

"Congratulations to the host for clearing the obscure aura and gaining 100 Yin Virtue!"

"Congratulations to the host for clearing the obscure aura and gaining 100 Yin Virtue!"

“……”

After harvesting all these accumulated obscure qi, Lu Nan found that he had earned another 400,000 Yin Virtue.

Now that he has more than 4.3 million Yin Virtue points, the feeling of getting rich like this is really refreshing, and he doesn't know how much Yin Virtue he can get in the end after finishing this ancient formation.

It stands to reason that according to the data on the personal attribute panel, two million Yin Virtue is enough to advance, why hasn't the system promoted itself yet.

Lu Nan was a little worried, did he have to complete this ten-ring task in order to be officially promoted?

Then it's too painful, it's limited by the task, it's too bad.

“duang…… duang…… duang……”

Just when Lu Nan was worried, suddenly, duang appeared in the ancient formation...... The sound of duang.

All of a sudden, all the formations of the ancient formation burst out, and at the same time, all the obscure qi that walked in the space flowed back like water.

Lu Nan realized that something was wrong, and he immediately sped up the speed of throwing out the Heaven and Earth Qingming Talisman, trying to get a little more Yin Virtue.

However, this time, all the Heaven and Earth Qingming Talismans he threw out were not good, and those obscure qi were like instantly recovering their spiritual intelligence, all of them avoided the Heaven and Earth Qingming Talismans, and they all returned to the formation in an instant.

Just as all the obscure qi was absorbed by the formation, all the formations above the formation also burst.

Lu Nan was a little stunned, although this ancient formation belongs to the university's high-level level, but it also has to be in line with common sense.

To be reasonable, if the formations are all bursting, then there is no formation, and the formations can only operate by relying on the existence of the formations.

And the formations of this ancient formation have burst, how could those obscure qi return to the formation, how could they disappear so magically under their own eyelids.

Lu Nan felt very incomprehensible, and the scene that appeared next solved Lu Nan's very incomprehensible problem, and at the same time, it also made him look shocked, and he clenched the artifact Tiancong Cloud Sword in his hand without clenching it.

At the same time, he quickly recited a mantra in his mouth, and as soon as he made a move, it was the strongest means of attack, the true trick of the Nine Heavens Thunder Divine Sword!

"All souls return to you, all qi return to you, the sky has to be clear, the earth has to be a peace, the gods have a spirit, all things have to be born, the power of the thunder of the brilliant sky, the thunder general, the thunder soldier, the thunder drum, the thunder essence, the heavenly general, the heavenly soldier, the heavenly drum, the flying gold essence, the fire wheel, the cloth Xun Qi, the goblin, the moaning, the five thunders are fast!"

"Edict!"

The purple divine dragon formed by the nine divine thunders instantly split down from the sky, and its momentum was like a rainbow, and it was unstoppable.

……

When all the formations of the ancient formation burst, ...... from the ground It is very likely that under the Nine Shadows, a big monster has emerged.

This monster was black, the kind of black that was extremely black, the kind of black that even light could swallow up, the kind of black that was even more terrifying than a black hole.

At the same time, this monster's body is huge, and the strongest thing is the vague aura that breaks through the sky on this monster's body, and the reason why this monster's body is huge is because this monster's body is made of various substances in the land.

On the other hand, this monster has the same limbs and head as humans, but that head is also black and does not have seven orifices.

As soon as this monster appeared, it pounced towards Lu Nan, which was also the reason why Lu Nan used his strongest attack method for the first time.

Although this monster does not have seven tricks, Lu Nan can surprisingly feel the anger of this monster and the emotion of wanting to kill him quickly.

It's the kind of hatred that seems to have been robbed of something beloved!

How could this monster hate itself?

Do you blame yourself for violently dismantling this ancient formation?

Or did you do bad things with good intentions and let this monster out?

Although he was thinking about these messy things in his heart, he didn't stop in his hand, and nine purple divine thunders had already slashed down towards the monster.

The nine purple divine thunderbolts did not directly slash at the monster, and then merged together and turned into a huge divine dragon.

"Boom, boom, boom!!"
