The situation in Tushen Castle is somewhat special. Although Su Dingshan is the master of a lineage, he lives in seclusion and is taciturn. He usually has his senior brothers from this lineage teach him the truth.

Therefore, the middle-aged man with an unattractive appearance in front of him has a very high status in Tushen Castle.

After hearing this, Wu Tiankui, Yang Lin and others all looked happy and fell to the ground at the same time: "Thank you, Senior Brother, for teaching me the Dharma!"

"alright."

The middle-aged man stretched out his hand to help several people up, and said with a smile: "We are all Master's direct disciples. Although Xue has taught the Dharma on behalf of Master these years, we cannot disturb the seniority. Such a great gift must never happen again."

Wu Tiankui and others looked at each other, and finally nodded in agreement.

"I have received all your things. This mission has been completed very well. Leave the rest to me." The middle-aged man said calmly.

Wu Tiankui, Yang Lin and others knew that he had issued an order to expel guests, so they stopped staying, said goodbye, returned the same way, and left the cave together.

Deep in the cave, under the dim oil lamp, the middle-aged man's face seemed a little excited.

He had already checked the contents of the storage ring and found nothing wrong with it, so he put it aside first and picked up the pale blue ice flower.

"Xuan Binghua... I've been waiting for you!"

The middle-aged man took a deep breath and tried to calm down his mood.

In fact, he encountered a bottleneck in practicing the "Book of Transformation of Dust". Because of the forced breakthrough, the skill backfired, and he had to use the properties of "Xuanbinghua" to heal the injuries in his body.

Although the breakthrough failed, it was not all without gain. Instead, he realized the essence of the "Book of Transformation of Dust" as a blessing in disguise. As long as the injury is healed this time, the middle-aged man's skill will be further improved, and he may even hope to break through the bottleneck of the Transformation Tribulation Realm!

Although the "Xuan Ice Flower" is not a high-end spiritual material, its quantity is very scarce. Wu Tiankui and others went down the mountain many times before and failed to purchase a single Xuan Ice Flower. The middle-aged man was almost disappointed. He did not expect that this time it would actually make him.

They brought one back!

"Finally, my injury can recover... After this injury is healed, I will also break through the bottleneck of the Tribulation Realm!"

When the middle-aged man thought of this, he felt excited and hurriedly cast a spell to make the "Xuan Binghua" float in front of him. Then he sat cross-legged on the futon and prepared to use his skills to refine it.

But at this moment, a ray of cyan rays of light suddenly shot out from the "Xuan Binghua", and the speed was so fast that the middle-aged man had no time to react before the ray of cyan light penetrated into the center of his eyebrows!

His eyes instantly became confused, and he was completely different from the mighty and serious "elder brother" before.

The next moment, the middle-aged man stood up from the futon.

He was seen dancing and dancing, his hands were forming strange seals, and he was starting to mutter something.

Not long after, the middle-aged man's face became solemn, and he simultaneously cast a spell with both hands. His spiritual power surged out, and all of it was poured into the "Xuan Binghua" in front of him.

A mysterious rune appeared on the blue ice flower. If there are masters in the Tribulation Realm present, they will definitely recognize that this is an extremely exquisite sealing technique!

As the middle-aged man continued to cast spells, the sealing runes on the "Xuan Binghua" gradually disappeared.

After ten breaths, the seal was completely released, and a powerful aura emanated from the ice flower...

The middle-aged man remained expressionless, as if everything in front of him had nothing to do with him, or he simply couldn't see what was happening in front of him.

In the sky above the "Xuan Binghua", a figure gradually took shape.

This man in gray robes, tall and handsome, is Liang Yan who has disappeared for many days!

Although his face was calm, there was a trace of joy that could not be hidden deep in his eyes.

"Tushen Castle... No matter how perfect your barrier is, I won't be able to sneak in in the end, hahaha!"

No wonder Liang Yan was so excited. In order to complete the mission of Wushuang City and find the entrance to Tianji Pavilion, he did make some dangerous moves this time.

Because the barrier of Tushen Castle can detect the identity of the person entering, you must wear a disciple token to enter safely. In order not to expose any flaws, Liang Yan simply sealed himself inside the "Xuan Binghua" and asked Wu Tiankui and others to

Bring yourself into the Tushen Castle!

He knew that the detection ability of the barrier was extremely strong, and as long as a trace of breath leaked out, it might be seen through, which would be equivalent to throwing yourself into a trap.

Forced to do so, Liang Yan could only cast the seal perfectly and completely. This made it impossible for him to break the seal from the inside, and someone had to break it for him from the outside.

In order to allow him to come out smoothly after entering the Tushen Castle, Liang Yan left a restriction on the surface of "Xuan Binghua".

As long as someone tries to refine this object, he can capture the other person's soul, and then control the person to break the seal from the outside and release himself.

Although this method is clever, it is extremely risky because there are too many unpredictable things! If no one refines the "Xuan Binghua", Liang Yan will be trapped in a cocoon and put himself in a dangerous place!

In normal times, Liang Yan would never adopt such a radical plan.

But now, as the palace master of Bihai Palace in Wushuang City, he must find the mark left by Li Yile before Canglong crosses the tribulation, and cooperate with Li Yile and Qin An to complete the mission!

Moreover, the entrance to Tianji Pavilion is also here.

Whether it was for his own opportunity or to fulfill his obligations as the master of Bihai Palace, he had to do this.

Fortunately, the final result is good.

After the middle-aged man got the "Xuan Binghua", he couldn't wait to start refining it, and finally fell into Liang Yan's trap and released him.

At this moment, Liang Yan had successfully sneaked into the barrier of Tushen Castle.

He looked around and saw that this was a deep secret room, which seemed to be located inside the peak of Tushen Castle. There was a passage in the distance with many branches at the end, which seemed to extend in all directions.

"It seems that Tushen Castle built an underground palace inside the mountain..."

Although he sealed himself in the "Xuan Binghua", he still heard the conversation between Wu Tiankui and the middle-aged man just now.

Exquisite fairy trees, closed mountains, and secretly collected treasures...

Everything shows that the interior of Tushen Castle is by no means simple, and there must be some ulterior secrets inside!

Liang Yan looked at the confused and somewhat demented middle-aged man. After pondering for a moment, he suddenly stretched out his right hand and pointed a finger at the man's forehead.

As a surge of spiritual power poured in, the middle-aged man's eyelids immediately drooped.

"Plop!" With a sound, the man fell down on the futon, his original dull expression gradually disappeared, and a wisp of blood appeared on his face.

Liang Yan unlocked his soul-obsessing technique.

The person in front of you will wake up soon, and when he wakes up, although he will be a little confused, he will not remember what happened just now.

Liang Yan took one last look around, without hesitation, pinched the magic formula in his hand, and his body immediately turned into a wisp of smoke, which quickly penetrated the surrounding walls and disappeared without a trace...

.

After a while, the middle-aged man woke up leisurely.

He glanced at the "Xuan Binghua" floating in front of him, then looked around the cave, with a trace of doubt on his face.

"Huh? What seems to have happened just now?"

The middle-aged man murmured to himself, his consciousness spread out, and he carefully searched every corner of the cave, but found nothing.

"Strange! Could it be that the injury in my body recurred, causing my consciousness to become confused for a moment?"

After much thought, he found that this was the only explanation that made sense.

After all, you are in your own cave, and there is no one else here. Besides, the entire Tushen Castle is shrouded in a barrier, who else can get in?

"Well, it's probably because I've been overthinking it. Ever since I went crazy in my practice and was attacked by the technique, I've often been restless. I guess it's the same this time... I have to refine the 'Xuan Bing Hua' as soon as possible.

', to get out of this predicament!"

Thinking of this, the middle-aged man strengthened his thoughts.

He sat cross-legged on the futon, pinched the magic formula with both hands, and shot out a series of spiritual lights, and continued to refine the "Xuan Binghua" in front of him...

...........

After Liang Yan left the middle-aged man's cave, he immediately used the earth escape technique and went deep underground.

He had unlocked the two seals of Tianji Pavilion. According to the map, the entrance to Tianji Pavilion would automatically appear in his mind.

This is indeed the case. He could not sense it before because the barrier of Tushen Castle blocked his consciousness. Now that he has successfully blended into the interior of Tushen Castle, the induction in his mind has become stronger and stronger. The entrance of Tianji Pavilion,

Right in the heart of this mountain!

There is still half a day before the Canglong Tribulation, so Liang Yan is not in a hurry to find the location of the Exquisite Immortal Tree.

He decided to look for the entrance to Tianji Pavilion first.

Because you have the Tianji Pearl in your hand, you have the key to the Tianji Pavilion ruins. If something dangerous happens and you can't handle it, you can hide in the Tianji Pavilion ruins, which gives you a way out.

Relying on the location sensed in his mind, Liang Yan used the earth escape technique and carefully sneaked deep into the mountainside of the Tushen Castle.

About half an hour later, he found that his escape light was stuck halfway, making it difficult to move forward.

"what happened?"

Liang Yan frowned slightly, with a look of surprise on his face.

The next moment, his spiritual consciousness spread out, and he carefully checked the surroundings. Only then was he surprised to find that the surrounding soil had become very hard from unknown time, and it would be difficult to break it even with magic weapons!

Just when Liang Yan was at his wits' end, the glow of the Taixu Gourd flashed, and Lao Jin's figure appeared beside him.

Lao Jin transformed into a Taoist. After carefully observing the surroundings, he said with a solemn expression: "Something is not right here. The surrounding soil is not ordinary. It seems that it has been refined by special means to block the monks' earth escape progress."

After Liang Yan heard this, he immediately became alert.

"Have we been discovered?"

"That's not..." Lao Jin pondered: "In my opinion, these soils are like a city wall. The reason why they exist here is just to protect the things deep in the mountain."

"If you say that...the secret of Tushen Castle is actually hidden here?"
