"This is... Cloud Spirit?"

Lin Yun examined the ball of white, crystalline mist in his hand and asked curiously.

Could this be a rare treasure from the fifty-first floor of the Heavenly Dao Tower? Lin Yun wondered to himself.

Thinking this, Lin Yun, just like he had done with the gray crystals before, used his fingernail to cut off a small piece and put it in his mouth.

"boom--"

A powerful energy exploded on Lin Yun's tongue and quickly entered all parts of his body.

Unlike the spiritual energy transformed from the gray crystals that surged into Lin Yun's mind, the power transformed from these cloud essences surged into Lin Yun's limbs and bones, giving him a gentle, subtle feeling throughout his body.

Lin Yun could clearly feel that his body and martial arts power were rapidly becoming stronger.

"This cloud essence can actually enhance physical strength and martial arts power?" Lin Yun was shocked and asked.

Then, he was overjoyed. His main practice was martial arts, and physical strength was also a part of martial arts. The effect of this cloud essence was of great significance to him.

"The effects of this cloud essence are no less than those gray crystals. The Heavenly Dao Tower actually provides so many powerful natural treasures. It's truly amazing..." Lin Yun exclaimed.

The fact that the Heavenly Dao Tower had provided such powerful natural treasures on the 50th and 51st floors made him extremely impressed and grateful for the tower's generosity.

"call!"

Without further hesitation, Lin Yun swallowed the entire cloud essence in one swift motion.

"Boom!"

A massive surge of energy exploded within him, spreading throughout his body and rapidly strengthening him.

One hour... two hours... three hours...

Lin Yun closed his eyes and carefully experienced it.

"In terms of energy attributes, this cloud essence should belong to water, which is perfect... Previously, I used a lot of Super Golden Source Liquid. Although the effects of Super Golden Source Liquid are incredibly powerful, its attribute is metal, which is somewhat too masculine in some aspects... I can't use too much, otherwise, it will be detrimental to the growth of various powers... Water-attribute natural treasures have fewer such concerns..."

"As the saying goes, 'The highest good is like water, which benefits all things without striving.' Water-attribute natural treasures, when used appropriately, generally have great benefits for the body... Furthermore, metal generates water, and to some extent, the energy of the cloud essence also alleviated some of the hidden damage to my body from the previous Super Golden Source Liquid..."

Lin Yun thought to himself.

Previously, the Super Golden Source Liquid had caused some minor, hidden damage to his body, which he was aware of. However, every medicine has its side effects, and he couldn't avoid this situation as long as he relied on external aids for cultivation.

He just needs to spend some time nurturing and allowing these minor injuries to heal slowly.

Now, Lin Yun discovered that this cloud essence energy was speeding up the process considerably, how could he not be happy?

This means that he can even consume more Super Gold Elixir.

"Gray crystal, cloud essence, and super golden essence liquid—I have three powerful natural treasures at my disposal. With these, I have a high chance of breaking through to the Super Realm before leaving the Heavenly Dao Tower..."

Lin Yun opened his eyes, a confident glint in them, and said in a low voice.

As he spoke, he flipped his hand and took out the Bloodthirsty Sword.

"Little Blood, could you help me refine this cloud essence power?"

Lin Yun transmitted his voice to Little Blood within the Bloodthirsty Sword, his tone calm and revealing nothing of his feelings.

Three hours allowed him to clearly sense the details of the cloud essence's energy. He was fairly certain that this energy was harmless to him and that he could use it with peace of mind.

If Xiao Xue can help him refine this energy, he can save a lot of time. In that case, he will have more time to break through to higher levels and have a greater chance of obtaining more rare and precious materials.

However, Xiao Xue's previous performance made him realize that Xiao Xue was hiding a lot of strength, so he didn't want to give Xiao Xue too much credit, lest this guy think he was easy to fool.

"Um?"

But at that moment, Lin Yun noticed that the crimson light cluster representing Little Blood inside the Bloodthirsty Sword was "trembling."

What happened to Xiao Xue?

Lin Yun exclaimed in surprise.

This was the first time he had ever seen this guy in such a state.

"Brother, Xiao Xue must have overexerted too much power just now, that's why she's like this..." Xiao Bai's hesitant voice came.

"Overdrawing power? You mean this guy just overdrawn a lot of power?" Lin Yun was stunned. He covered the blood-red light ball with his mental energy again and said in disbelief.

In his mind, this little blood was very cunning. How could he possibly do something that harmed himself and benefited others?

Although he is now the master of the Bloodthirsty Sword, he knows that he is only the nominal master of the Bloodthirsty Sword. This little blood has never recognized him as its master.

According to Lin Yun's perception, the crimson light cluster representing Xiao Xue was indeed very "weak".

"Could it be that this guy... really overdraws a lot of his power..." Lin Yun remained silent, and for some reason, a sense of apology arose in his heart.

Perhaps he has always misunderstood this little blood?

The other party can't speak yet... Perhaps, the cunning they showed was just a subconscious way of protecting themselves?

Previously, he kept telling this little blood to use all its strength. Did this little blood really take it seriously? And then... it kept overdrawing its power to help him?

If that's the case, then his sin is truly grave.

How could they possibly fool a spirit with such low intelligence like that?

"How... how do I restore it?" Lin Yun asked Xiao Bai telepathically.

"Those gray crystals should be able to restore Little Blood's strength..." Little White hesitated.

As a spirit itself, it knew all too well how beneficial the spiritual energy contained in those gray crystals was to them.

"Alright, I won't take the spiritual energy from this gray crystal. You and Xiao Lan can absorb some, and use the rest to restore its power!" Lin Yun said after thinking for a moment.

As he spoke, he flipped his hand and took out a gray crystal, placing it next to the Bloodthirsty Sword.

Because his mental power had already broken through to the half-step super realm, a small amount of gray crystals could not cause a qualitative change in his mental power. Therefore, the gray crystals he obtained at the end of the fiftieth floor of the Heavenly Dao Tower were not refined by Xiao Xue on the spot.

At this moment, it is just right to use it on this little blood.

Anyway, Xiao Xue also contributed a lot to obtaining these gray crystals.

It's not a loss to let this little blood be used.

Lin Yun thought to himself.

"Little Blue and I don't need to absorb it either, let Little Blood absorb it all!" Little White shook his head repeatedly and said.

"Yes, let Little Blood absorb it himself!" Little Blue agreed.

Inside the Bloodthirsty Sword, they sensed Little Blood's previous "desperate" actions more clearly because they were not the sword's own spirit. In this respect, they could not help Lin Yun as much as Little Blood. They were very grateful for Little Blood's "desperate" behavior.
