Yang Chen guessed that there must be a hidden secret in this wizard tower.

Ciri and Duke Sr. also frowned, this was not the result they wanted......

Both Duke and Ciri hope to find out what they can do about the Wizard Tower, and no matter how bad it is, they need to figure out the relationship between Jasmine the Night Elf and the Wizard Tower.

Although the dark wizard was very unfamiliar with the night elf Jasmine before, there are all kinds of signs that Jasmine and the dark wizard have an inextricable connection with the wizard tower before, and this connection may be very hidden, and even the sky-level dark wizard may not be aware of it!

Yang Chen carefully recalled the details he had just searched, and he was very suspicious, there must be a dark room in the wizard tower, but he couldn't find out where it was......

Wait a minute......

At this time, Yang Chen unconsciously turned his head and saw the corpses of the black-robed wizard and the three-headed dog......

He put aside some of his subjective emotional influences, and began to think carefully about a suspicious point, where did the three-headed dog and the black-robed wizard come from?

"Ciri...... You were the first to discover the three-headed dog, can you recall which direction the three-headed dog was killed?"

Ciri was stunned for a moment, bowed his head and silently recalled......

After a while, Ciri said with some frustration, "I really can't remember, I just know that it was killed from my right hand......"

On the right-hand side?

Yang Chen listened to what Ciri said, subconsciously walked to the staircase and turned to the right.

Nothing out of the ordinary, this is the staircase, and the right hand side is just a wall......

Yang Chen stepped forward a few times, and knocked on the wall on the right with his hand solemnly.

"Knock knock!"

Yang Chen moved lightly again, feeling the sound echo on the wall as he knocked.

"Tom tom!"

The voice has changed......

Yang Chen hurriedly got up, and tapped at the place where the sound was obviously different from other places......

Secretly groping for a while, Yang Chen didn't notice any difference......

"What's wrong, did you find anything?"

Seeing this, Ciri moved lightly to Yang Chen's location.

"You're just in time, unleash your most powerful blow and attack here......"

As he spoke, Yang Chen pointed lightly again......

Ciri nodded slightly, and the power of the rules began to condense and gather, and the void above the tip of the sword had begun to twist slightly, as if it was refracted by the air around the flames......

"Broken!"

The long sword stabbed with the body!

"Smack!"

"Da Da Da!"

I saw that the long sword stabbed against the wall and was easily bounced away, and I didn't notice it, so that Ciri couldn't help but take a few steps back......

"What the hell, it's so hard......" Yang Chen scolded as if cursing.

He was pretty sure that there was a problem with this place, and if it was right, this should be the entrance to the hidden laboratory......

But how do you break it?

Yang Chen was also helpless for a while, the mechanism was set up cleverly, even the walls were so thick, for fear that someone would destroy the mechanism.

"By the way, I still have insight!"

Yang Chen patted his head, when he first set foot in the other world, he relied on insight to guide the direction......

Insight is also known as the Guiding Technique, although most of them will take a long detour, but it has to be said that the path guided is often the easiest and safest.

As soon as Yang Chen's mind moved, a gray mist stretched out towards him.

"This ...... What is this?"

Ciri was startled by the gray mist that had just appeared, and hurriedly asked subconsciously.

"This is a secret technique of my master, which can help to gain insight into the secret realm and guide the path!"

"This ...... So amazing?"

Ciri shuddered as he watched the mist emerge into the distance.

Such a strange secret technique, if it was really as effective as Yang Chen said, it was really a well-deserved battlefield magic skill.

If nothing else, just guiding the path is amazing.

For example, when the two armies were fighting and the strength was almost the same, one side wanted to use the decapitation tactic, so it decided to attack the enemy's base camp at night to provide cover for the decapitation team.

But he never thought that because of the number of assassinations, the enemy commander was already very cautious. There are dozens of command tents alone, and who knows if there is really a commander in these dozens of tents?

Painstakingly assigned a decapitation operation, but missed the opportunity because it was not accurately located......

And with Insight, you can hook up with the world's origin power, easily calculate the true location of the opponent's commander, and kill him in one fell swoop!

In this way, the Insight Technique can be regarded as a well-deserved battlefield magic skill...... Not to mention that he also has precise guiding effects...... It can point out a clear path in a complex battlefield situation.

"What are you doing in a daze? Hurry up and call old Duke to join us...... I'd like to see what secrets are hidden in this dark room that deserves so much trouble from the dark wizards of the Sky Realm......"

The gray mist rose, and Yang Chen found that the end point of the gray mist was not where he had just found, instead, the gray mist began to spread towards the door of the wizard tower.

Although Yang Chen had some doubts in his heart, according to the detour attribute of the insight technique, it was also reasonable.

After all, the insight, the path chosen, is always the safest and most appropriate, not the closest......

Yang Chen walked with everyone while continuing to release his insight technique......

When Yang Chen was in the Warcraft Forest, because his spiritual power was not rich enough, and he was not familiar with the mastery of spiritual power, he could only indirectly cast the insight technique, and according to the rhythm of the fog every second, he walked out of the Warcraft Forest little by little.

And now, Yang Chen has already set foot in the transcendental, and his spiritual power has ushered in a transformation, coupled with the previous hard practice of magic and meditation, the spiritual power at this time has changed earth-shaking compared to when he first entered!

There was no way to maintain the Insight Technique to make Yang Chen feel powerless, on the contrary, with the help of the natural recovery of spiritual power, he could actually be on par with the consumption of the Insight Technique.

The group of people did not stop, followed the gray mist for a while, and finally came to a big banyan tree.

There is naturally nothing strange about this banyan tree, but when everyone entered the wizard's tower just now, they all ignored this huge banyan tree.

This in itself is somewhat abnormal......

"Wait...... This is ......" Old Duke looked at the big banyan tree, but there was a hint of surprise in his heart, he looked at the green light in the heart of the big banyan tree.

"Seniors know?" Ciri asked, looking at it and asking with some curiosity.

Although Ciri is not proficient in anecdotes, after all, he was born in the Cecil family, and the education he received since he was a child is naturally different from that of ordinary people.

Something she didn't recognize, but old Duke knew......

Yang Chen glanced at the two of them, and then looked at Old Duke quietly.

What Ciri didn't know, Old Duke could actually answer, which couldn't help but make Yang Chen suspicious of his identity. Old Duke: This is not something that can be explained by experience.

"This is the leaf of the World Tree...... Old Duke saw that Ciri and Yang Chen were looking at him with curious eyes, especially Yang Chen's kid, who couldn't wait to see himself thoroughly......

So he panicked and said frankly.

"What?!" two startled voices rang out at the same time.

Naturally, it was Xili and Yang Chen.

Ciri was aware of the power of the leaves of the World Tree, but Yang Chen was completely because of something else......

"The World Leaf, which is said to have a strong vitality, is the supreme treasure for cultivating the laws of the natural wood system!" Ciri couldn't help but mutter.

"But the question is, what's the use of a dark wizard collecting this kind of thing...... He majored in the law of poison and minored in the curse system, what does it have to do with the wood system and the natural department?"

Ciri's face was already full of doubt.

She didn't understand why the Dark Wizard had collected such a useless leaf and placed it in the heart of the Great Banyan Tree......

"......No," Old Duke explained, looking at the leaves of the World Tree, "Actually, poison is also a branch of the wood attribute......

"Huh?" Ciri scratched her head, a little overwhelmed, in her opinion, one is to save people and the other is to harm people, it should be natural opposites.

"It's not surprising that some herbs can be used to cure diseases and save people, and they can also be used to prepare poisons...... Wood is as powerful as poison!" Yang Chen explained.

"I see...... Ciri nodded as if he didn't understand......

Old Duke continued, "That's right, the wood attribute not only contains strong vitality, but also rich in poison, even for a giant tree like the World Tree...... After a pause, Old Duke touched his chin again and said, "If my expectations are correct, there must be a dark room dedicated to cultivation under this big banyan tree...... Placing the World Tree Leaves in the Heart of the Banyan Tree, and then cultivating with the help of the Banyan Tree's huge and developed root system, the Dark Wizard is really a genius!"

"It's not just like that...... Yang Chen said with a solemn face, "As far as I know, once a person's brain is taken out, it is easy to lose its vitality, but if it is soaked in such a strong vitality, then it is still possible to ensure a certain vitality of the brain...... So ......"

Yang Chen looked at the root system of the big banyan tree with cold eyes, and said, "I speculate that under this banyan tree, there must be a place used by dark wizards to conduct human experiments......

As soon as these words came out, everyone's faces changed, the dark wizard was really ruthless, with the help of the power of the leaves of the world, he was actually carrying out such an evil and bloody experiment......

"That'...... How do we get in?"

Ciri couldn't help but ask, she couldn't describe her mood at this time, it was very complicated......

"Follow the gray mist,......" Yang Chen said directly, "Since the gray mist has led us here, there must be a path to enter it...... Although, I've always thought that the main entrance to this underground chamber should be in the wizard's tower......"

Yang Chen said that it was not that I didn't want to go to the main gate, but because the insight technique had taken a long detour again......

After hearing this, everyone followed the gray mist closely, and after a while, they came to the foot of the big banyan tree......

"What kind of road is there here?"

Ciri looked around and couldn't help but ask.

"Look there......" Yang Chen pointed in the direction of the gray mist......

Old Duke and Ciri looked curiously in the direction of Yang Chen's fingers, and after seeing them clearly, they couldn't help but glance at each other, and the corners of their mouths twitched slightly......
