After half a day, the elixir in the medicine field became a lot more sparse, and the ground was also a little potholed.

Zhao Sheng was very careful to put the last red fire mushroom into the storage bag.

Then, he took out the elixir seeds that he had prepared long ago, carefully sprinkled them in the vacant place of the medicine field, and finally buried them with soil.

After doing these things, Zhao Sheng suddenly found himself encountering a thorny problem again.

What about that Blood Treasure Tree?

His storage bag has limited space and he can't take it with him.

Kill the golden goose?

Zhao Sheng would never do this kind of stupid thing.

As long as the Blood Treasure Tree is alive, it will have a steady stream of blood production.

A long stream of water is king!

Zhao Sheng thought about it for a while and decided not to move it for now.

Not only that, Zhao Sheng also temporarily extinguished his desire to extract blue blood.

Extracting blood will inevitably greatly affect the growth of the treasure tree.

At this time, Zhao Sheng had already given birth to greater ambitions in his heart.

If you wait until the next life...

Thinking of the wonderful future, Zhao Sheng couldn't help but laugh.

Oh time! Always be on his side.

After resting for a while, Zhao Sheng took out a pickaxe from the storage bag and slowly walked to the pile of rubble on the mountain wall.

Bang bang bang!

With the sound of digging and knocking, Zhao Sheng began his journey of digging holes.

The spiritual veins must be hidden inside the mountain.

What Zhao Sheng had to do now was to dig out a passage to the land of spiritual veins.

After digging for a while, Zhao Sheng suddenly stopped his movements, and his expression became a little shocked.

There are also thick tree roots growing inside the mountain wall?

It looks like the remnants of a mysterious giant tree that is incredibly large.

And looking at the direction of the tree's roots, it seems to grow towards the spiritual veins.

In order to test this idea, Zhao Sheng took the initiative to dig into the interior of the mountain along the course of the roots of the tree.

Two days later, Zhao Sheng had dug a tunnel three feet deep and one person high.

Standing at the end of the tunnel, Zhao Sheng could feel a slight increase in the concentration of aura around him.

It's tiny, but it's recognizable.

As it turned out, he was right.

As the excavation progressed deeper, Zhao Sheng was distressed to find that the tree roots in the mountain had become dense, often hindering his excavation.

Despite this, Zhao Sheng was careful to avoid these roots.

Because the roots here not only look more "fresh" than those on the slopes, but also faintly glow with a hint of life.

This made Zhao Sheng extremely pleasantly surprised.

A certain thought that he had in his previous life resurfaced in his mind at this moment.

……

A month later,

Zhao Sheng stumbled out of the cave passage and dumped the gravel from the storage bag onto the huge pile of stones next to the cave.

After a month of continuous excavation, the length of the passage has exceeded 100 zhang. But there is still no trace of the spiritual vein, but the spiritual energy concentration has increased significantly, almost comparable to the spiritual energy concentration of the core of the spiritual vein of Longli Lake.

There are all kinds of indications that the grade of this spiritual vein is higher than that of the Longli Lake spiritual vein, and even a second-order spiritual vein may not be possible.

After pouring the stones, Zhao Sheng was about to return to the cave, but suddenly heard a series of rumbling noises from the clouds and mist overhead, like the muffled thunder that continued to explode on a thunderstorm, and the thunder sound came from far and near, oppressively.

"What's going on?"

Zhao Sheng's expression was surprised, and he faintly had an ominous premonition.

At this moment, he suddenly heard a fine clicking sound coming from the mountain wall, as if something was freezing.

In an instant, Zhao Sheng felt that the outside temperature had plummeted, and then he saw that there was frost on the mountain wall that quickly condensed out.

As a screaming sound suddenly crossed his ears, a cold current rushed down from the mist above, brushed Zhao Sheng's scalp, and instantly hit the mountain wall.

In the blink of an eye, a thick patch of white frost condensed near the mountain wall.

The temperature of the cold snap was extremely low, and the chill was biting, which made Zhao Sheng's face numb, and his hands and feet became a little stiff.

Zhao Sheng suddenly changed color when he saw this, and exclaimed, "Not good! This year's cold spell has been brought forward. ”

At this moment, the surrounding dense fog began to become disorderly, and countless cold cyclones suddenly descended from the sky, constantly stirring the surrounding dense fog.

Once again, the temperature has dropped dramatically,

Zhao Sheng saw that countless white ice chips suddenly appeared in the mist, falling in a row, looking very much like ice and snow.

But he knows that this kind of ice chips is far more "cold" than ice and snow.

As the temperature drops to freezing, the surrounding fog concentration plummets.

Zhao Sheng suddenly found that his vision had never been so clear.

But he wished it hadn't happened.

Zhao Sheng looked up at the sky, but saw that the end of his line of sight was occupied by infinite white.

To his horror, a white line emerged from the sea of clouds above, from top to bottom, from left to right, and I don't know where it extended.

The white cold wave is endless, crushing everything with the momentum of destroying and decaying.

With the height of Tianzhu Mountain, it is not uncommon to have a cloudy wind and cold wave, which is a reflection of the unique climate of Tianzhu Mountain.

But every year when the cold wave arrives, there are traces to escape, and it is not as abrupt as it is today.

The weather is cold and heavy, and it should have descended naturally, but the cold current of Tianzhu Mountain is known for its chaos.

Under the disturbance of the swirling weather, countless cold currents between heaven and earth turned into bone-chilling "ice guns", stabbing thousands of feet, carrying the surrounding clouds and mist whistling back and forth.

This kind of vast vision, if you don't see it with your own eyes, it is difficult for ordinary people to imagine it.

This is a natural disaster!

It's beyond human power to stop it!

Just when Zhao Sheng wanted to hide in the cave, the demon beasts and fierce birds living in this area also sensed the impending cold wave.

These monster beasts and fierce birds, who are usually not afraid of death, seem to be very afraid of this cold wave. They fled, or jumped down, or hid in the crevices of the rocks,

Whatever the choice, it is to avoid this natural disaster.

In the blink of an eye, the creatures in Zhao Sheng's sight had decreased by more than half.

But there was also a small half of the unlucky ones, who did not have time to avoid the cold wave and were swallowed up by the cold wave halfway through.

"Something is wrong!"

"What a big problem!"

It is also in Tianzhu Mountain, but it is on the sunny side, and countless medicine pickers look at the snowflakes falling from the sky, and their faces have changed greatly, and their hearts are shocked.

Most of the immortal cultivators are very superstitious.

Most people are convinced that the cold wave in Tianzhu Mountain will not be advanced for no reason, and it will be three months earlier.

It must be an omen. And the sea of clouds in the upper layer of Tianzhu Mountain must have undergone some kind of great change.

Maybe there's a catastrophe coming, or maybe there's a new secret realm born!

On the other side, in the Slope Elixir Garden, Zhao Sheng was quickly packing up his hands.

At this time, the surrounding fog is blown into ice particles by the cold air, dancing wildly in the wind, oozing a suffocating chill.

The cold wave advanced extremely fast, and countless demon beasts fell into a frenzy of killing in order to survive.

When entering the cave, Zhao Sheng turned around and looked up, and at a glance, the flesh and feathers were flying in the sky, countless monsters, beasts and birds, all fled and fought in the air, and the sound of beasts and birds resounded in the sky.

Bang bang!

Zhao Sheng quickly moved a large pile of rubble and blocked the entrance to the cave.

Soon the cave was dark and his fingers were gone.

Kiss!

After a soft sound, a fist-sized fireball suddenly appeared in Zhao Sheng's palm,

The fireball made the cavern light up instantly.

With light, people instinctively relax.

Listening to the faint whistling sound outside the cave, Zhao Sheng's nervous mood was surprisingly calm.

Soon, he lit a fire to resist the cold around him.
