The Evil Flame Mountain is so big, and it is impossible for the protective barrier to cover the entire Evil Flame Mountain.

Therefore, Lu Lan's idea is very simple.

Let's see if we can sneak a detour to the back of the Evil Flame Mountain, looking for an opportunity to cause chaos at the Evil Flame Gate from the inside, so that the protective barrier will be useless as soon as possible.

In addition to this, he has another purpose.

That is to look for traces of the existence of the sealing formation.

Since these so-called "gods" are all sealed, they will inevitably leave traces of sealing.

Unless they came to the Cangyuan Continent by forcibly breaking the seals, those seals should still be able to activate and seal the other party back again.

That's what he did when he gathered in Cave Mountain.

The front of the Evil Flame Mountain roared and shook the sky, and it was endless.

And Lu Lan and the three of them quietly came to the back of the Evil Flame Mountain from the side of the Evil Flame Mountain, and the roar in their ears gradually became much quieter.

At this time, all three of them were in a state of invisibility.

Lu Lan cast [Meng Ji Shadowless].

Chu Tiantian used the Cloud Han Sect's Hidden Shadow Technique.

Only Chu Yun was the one who took the Shadow Pill refined by Lu Lan to hide his figure.

There is no way, with the level of the Chu family in Baitao City, it is impossible for them to have such a mysterious skill as concealment.

Lu Lan also tried to pass on the magic of [Meng Ji Shadowless] to Chu Yun, so that Chu Yun could comprehend and cultivate.

But this is obviously not something that can be done all at once.

Therefore, Chu Yun could only take the Shadow Pill to hide his figure first.

"Brother Lu Lan, if there is also a so-called 'Heavenly God' in the Evil Flame Gate......"

Chu Tiantian hesitated for a moment, then asked:

"Will he find us?"

“……”

Lu Lan pondered for a moment and shook his head:

"I don't know...... However, I don't believe that they are real gods, and naturally I don't believe that they really have the so-called 'divine power'. ”

In Lu Lan's opinion, if the other party was a true god, it was absolutely impossible for him to be sealed by the powerhouse of the Cangyuan Continent ten thousand years ago.

Otherwise, wouldn't those powerhouses in the Cangyuan Continent ten thousand years ago be stronger than gods?!

Lu Lan told his guess, which relieved the pressure on the aunt and nephew a lot.

Come to the back of the Evil Flame Mountain.

Lu Lan and the three of them all sensed the aura in front of them.

Sure enough.

With the sheer extent of the Evil Flame Mountain, it was impossible for that protective barrier to envelop the surroundings of the Evil Flame Mountain.

However, there are quite a few disciples of the Evil Flame Sect stationed here.

But basically they are all disciples of the True Xuan Realm and a small number of early Xuan Yuan Realm.

An opponent of this level was no threat to Lu Lan and the three of them at all, especially when they were in a state of concealment.

Therefore, as soon as they encountered those Evil Flame Sect disciples guarding the rear, they eliminated them all with little effort.

At this time, Lu Lan saw that some trees along the mountain road were quite strange.

Most of the trees looked as if they had been affected by the Evil Flame Mountain, and their roots and even leaves had turned black, as if they had been burned away.

However, some of the trees still maintained a normal and healthy turquoise luster, and even under Lu Lan's [Candle Dragon Pupil], they exuded a dull turquoise luster.

And these trees are also the ones with the largest trunks and the oldest ones.

"What's wrong? Brother Lu Lan, have you found anything? ”

Chu Tiantian saw Lu Lan stop, and he also stopped with Chu Yun.

Lu Lan continued to glance around with the [Candle Dragon Pupil].

It was found that the distances between the trees all seemed to be equal.

Not too far, not too close.

He walked over to one of the normal ancient trees and tried to inject the power into it.

Suddenly, he sensed the ancient tree in front of him trembling slightly.

In the picture in front of me, the blue-green luster on the ancient tree gradually brightened.

Suddenly, he felt something, like looking under his feet.

In his eyes, he could see a green light slowly spreading from the root of the ancient tree, extending towards another ancient tree.

But halfway through, it stopped.

"Tian Tian, you go to that ancient tree and inject Xuan power into the trunk!"

Lu Lan said loudly.

Chu Tiantian was a little unsure, but he still did it.

Then, Lu Lan saw that the originally dull luster in the ancient tree's body gradually brightened.

Like the ancient tree in front of him, a turquoise sinuous curve stretched out at the root, connecting with the light of the ancient tree.

Not only that, but there was not only one ray of light extending from under its roots, but also two other rays.

After the connection was successful, the glossy glow of the two ancient trees became brighter.

It seems that the ancient tree that Chu Tiantian pressed was like the "pivot point" in the formation, playing the role of a carrying force.

"I don't know what will happen if you connect all these ancient trees......

Lu Lan pondered for a moment and asked Chu Yun to repeat their actions in front of the third ancient tree.

The moment the three ancient trees were successfully connected, Lu Lan could clearly perceive that the aura on their bodies became more and more intense.

Under the bath of this breath, Lu Lan felt that his life breath had become much more vigorous.

Chu Yun and Chu Tiantian also felt the same way.

"It's amazing...... Brother Lu Lan, have you already discovered the extraordinaryness of these ancient trees? ”

Chu Tiantian asked out loud.

"I just found out that too...... And these ancient trees can not only enhance our breath of life, but also probably have another effect. ”

Lu Lan didn't explain what the "role" in her mouth was, but just said:

"You'll know when the time comes."

At this moment, he finally figured out why the trees next to him were obviously not so old, but these ancient trees were very tall and old.

It is very likely that these ancient trees are the sealing formations left by the super powerhouse who sealed the "god" on the Evil Flame Mountain ten thousand years ago.

As long as the light emitted by these ancient trees is connected, it may be possible to reactivate the formation again and seal the "god" of the Evil Flame Gate!

Lu Lan quietly walked over following the light that the [Candle Dragon Pupil] saw.

When he met a disciple of the Evil Flame Sect who was guarding the ancient tree in front of him, he directly dealt with the other party without saying a word.

Then Lu Lan and the three of them continued to repeat their previous behavior.

The shouting and killing sound in front of the sky was still shocking, and the roar was endless.

Compared with the coalition forces on the front line who are desperately attacking the protective barrier, Lu Lan and the three of them have come this way, and it is much easier.

They had little to no trouble sneaking into the depths of the Flame Gate.

On the way, he even came across the treasure house of the Evil Flame Gate, and without hesitation, he scavenged all the treasures inside.

"Brother Lu Lan, should we ...... Secretly go and kill those people? ”

Halfway up the mountainside, Chu Tiantian looked at the disciples of the Evil Flame Sect who were holding the protective barrier below, and said in a cold tone.

Lu Lan thought for a while, shook his head, and said:

"Compared to them, I care more about the 'god'......"

"If you don't get rid of that 'god', it won't be useful to kill as many Evil Flame Sect disciples as you want."

As soon as he finished speaking, he suddenly stiffened.

A huge force, an aura that oppressed them so much that they could breathe suddenly surrounded them.

"Hehe, when did you get two little reptiles mixed in?"
