Mortal blood!

Thinking of this, Lin Fan looked at Mu Yan.

"Yan'er, although this is the elixir chamber of Taixuan Immortal King, the immortal energy is still very strong."

"In addition, we now have the Barrier Breaking Pill, so why don't we seize the time to practice in seclusion here first."

"How about we try to break through to the immortal realm as soon as possible and then go out?"

When Mu Yan heard this, a hint of surprise flashed in her beautiful eyes.

"Everything depends on the husband!"

Lin Fan nodded and went directly to the light mask where the barrier-breaking elixir was stored.

Secretly activating Qing Ming's spiritual eyes, Lin Fan looked at it for a while and then immediately punched it.

boom!

With a crisp sound, Lin Fan's fist landed directly on the light mask.

Unfortunately, even with Lin Fan's physical strength, he was unable to destroy the light shield.

This made Mu Yan look surprised.

"Unexpectedly, the protective light shield in front of us is so powerful. It seems that it is not easy for us to get the barrier-breaking elixir." Mu Yan said with a smile.

While speaking, Mu Yan flipped her palm, and a long sword suddenly appeared in her hand.

As the immortal power was rapidly injected into it, Mu Yan tried her best to slash it down quickly.

boom!

Another muffled sound came, and the long sword in Mu Yan's hand was knocked away by a powerful force in an instant.

However, the mask is still intact.

This made Lin Fan and Mu Yan's expressions become extremely ugly at the same time.

"What a powerful protective light. Even my full blow can't destroy it. It seems that it is not easy for us to get the barrier-breaking elixir."

Mu Yan smiled bitterly.

After Lin Fan comforted him, he took out the Demon-Slaying Fairy Sword without hesitation.

I thought that with the terrifying attack power of the Demon-Slaying Fairy Sword, I could easily deal with the light barrier in front of me.

However, Lin Fan never expected that when he activated the Demon-Slaying Fairy Sword to attack, the light shield remained motionless.

"Damn, what on earth is this? Why is the defense so powerful?"

Lin Fan was secretly surprised.

At this moment, a familiar voice suddenly came from Lin Fan's mind.

"Master, this is the famous Vajra protective shield in the ancient world of true immortals. Don't say that you are only in the late stage of true immortal. Even if you are in the late stage of heavenly immortal, you cannot destroy it."

The person speaking is the soul of the book.

Ever since Lin Fan ascended to the True Immortal Realm, I don't know what happened, but the book soul has been in a coma.

Unexpectedly, I didn’t wake up until now.

"Are you awake? Since you know that this is the famous King Kong protective shield, you should also know how to break the King Kong protective shield, right?" Lin Fan said happily.

Shuhun was silent for a moment before continuing to explain.

"Master, if you want to break the diamond shield, it is easy to say it is simple. It is also difficult to say it is difficult. You need to find the key to break the golden light shield."

"If we can't find the key to crack the Vajra shield, everything will be in vain."

Lin Fan's heart suddenly sank.

He also didn't expect that now, he could only watch helplessly and couldn't get the barrier-breaking elixir in his hands.

This made him even more depressed.

"What exactly is the key you are talking about? Do you have a specific description?"

"There are different types of true immortals who arrange the diamond protective shields, and the keys they use are also varied. However, according to convention, the keys they use should be related to their identities. Since this is the ruins of the alchemist's cave, it should be related to the things for alchemy. "

Shuhun guessed.

When Lin Fan heard this, his eyes lit up.

The next moment, he flipped his palm and took out the Taixuan Divine Cauldron.

Buzz!

As a stream of pure immortal power was injected into the Taixuan Divine Cauldron.

On the Taixuan Divine Cauldron, blazing flames suddenly appeared.

At the same time, Lin Fan clearly felt that a small crack appeared in the diamond protective shield that had not moved at all when he and Mu Yan had jointly attacked it just now.

As time goes by, the cracks become more numerous and larger.

I'm afraid it won't be long before the diamond shield will break by itself.

"This... really works!"

Lin Fan was extremely pleasantly surprised.

Mu Yan on the side couldn't help but look overjoyed when she saw that Lin Fan had used the Taixuan Divine Cauldron to destroy the Vajra protective shield.

"Husband, you are still smart. If you hadn't obtained the Taixuan Divine Cauldron a long time ago, even if we killed all the true immortals in Xuanyun Pavilion, we still wouldn't be able to get the barrier-breaking elixir!" Mu Yan said with a smile.

When Lin Fan heard this, he immediately understood why Fairy Xianyu would let someone set up the Tianjue Formation here.

"It turns out that Fairy Xianyu didn't intend to use the barrier-breaking elixir as bait. It's just that their Xuanyun Pavilion couldn't break through the diamond shield."

"Haha, this time it's really easy for me and Yan'er."

Lin Fan suddenly realized.

Only when he continued to pour immortal power into the Taixuan Divine Cauldron, and when the cracks on the Vajra protective light shield became more and more numerous and completely shattered, Lin Fan made a casual move and used the white jade bottle containing the barrier-breaking elixir to instantly fell into his hands.

Wow!

Opening the bottle cap, an extremely pure medicinal fragrance suddenly spread out.

The realms of Lin Fan and Mu Yan increased rapidly at this moment.

"The aroma of the medicine is so strong, it can actually improve my level in an instant. It seems that it is indeed the barrier-breaking elixir."

Lin Fan looked overjoyed.

But he did not give Mu Yan the barrier-breaking elixir.

Instead, he secretly put all the barrier-breaking elixirs into a mysterious copper bottle to strengthen them, and then handed one to Mu Yan.

"Yan'er, hurry up and take the barrier-breaking elixir! I'll protect you!"

When Mu Yan heard this, she couldn't help but look overjoyed.

"Thank you, husband. Over the years, I have always wanted to break through to the human immortal realm as soon as possible. Unexpectedly, today my dream finally came true."

"If so, I will take the barrier-breaking immortal pill first and break through to the human immortal realm as soon as possible."

Mu Yan smiled.

Before Lin Fan could react, her red lips had already kissed Lin Fan on the face.

Then, she sat on the ground contentedly, calming her breath and concentrating her mind.

Only after her mind was completely stable did Mu Yan take the barrier-breaking immortal pill.

Huh!

The aura on Mu Yan's body suddenly surged.

In just a moment, she reached the half-step human immortal realm.

But Lin Fan still did not dare to be careless at this moment. He stood aside seriously to protect Mu Yan.

But he did not know that when Lin Fan and Mu Yan hid in the secret room of the elixir, they took this opportunity to take the barrier-breaking immortal pill and break through to the human immortal realm.

The young man who was arranging a powerful formation outside the ruins of Taixuan Immortal King and waiting for all the true immortals to come out seemed a little impatient.

"Something is wrong. So many True Immortals went in, why are there so few who came out alive?"

"Did many people perish in the Taixuan Immortal King Ruins?"

At this point, the young man frowned.

After pondering for a long time, he swept his eyes around.

"You guys guard this place well, I will go in and see what happened inside."

"Wait, no matter who comes out, I will stop them, understand?"

As soon as the young man finished speaking, the ghost immortals nearby said in unison: "Understood!"

The young man smiled with satisfaction. He immediately turned into a stream of light and rushed into the Taixuan Immortal King Ruins.

Lin Fan, who was protecting Mu Yan, naturally didn't know about this.

At this moment, he was sitting quietly beside Mu Yan.

He took out all the storage rings he had just seized.

"These guys are all true immortals of Xuanyun Pavilion. They should have a lot of good things on them, right?"

"Especially Fairy Xianyu, who is the owner of Xuanyun Pavilion. There should be more good things in her storage ring."

"If so, while Yan'er is striving for the human immortal realm, I will take a look at what is in these people's storage rings."

When Lin Fan said this, there was a hint of expectation in his eyes.

With a pure immortal power injected into it, all the things in Fairy Xianyu's storage ring fell to the ground in an instant.

Looking at the piles of immortal stones and natural treasures, Lin Fan's eyes were filled with excitement.
