Tang Yan's method is actually very simple.

Exchange the elixir seeds, use the botanical power of the old village chief, let these seeds germinate, and then arrange a large array of spirits in the back mountain to nourish these elixirs.

With the support of the spirit crystal vein, the growth rate of these elixirs will be accelerated several times.

Of course, this is simple but for Tang Yan, if it is someone else, I am afraid it will be difficult to complete.

"It's a pity, if the ghost dares to be the three seniors, it will be easier." Tang Yan muttered in his heart, it was actually a little strange.

The three of them left overnight, according to the old village chief, as if there was something urgent.

And the old village chief also said that this time Xiao Tiancun owes the three of them a favor, and this favor must be repaid.

However, at present, I have not received a request for help from the three of them, and I think that the urgent matters they encounter can be solved by themselves.

Shaking his head and shielding these thoughts from his mind, Tang Yan stood on a high place, looked at his masterpiece in front of him, and nodded with satisfaction.

The Spirit Gathering Array also cost him 100,000 points, but the effect made him extremely satisfied, he already felt that as he laid down the Spirit Gathering Array, the surrounding heaven and earth spiritual qi was constantly surging towards the back mountain, and those elixir shoots were also greedily absorbing these spiritual qi.

"Just wait for Chen Mengmeng!"

As soon as he thought of this, Tang Yan suddenly felt a slight tremor under his feet, and a strong and familiar momentum flashed away.

"Breakthrough?" Tang Yan raised his eyebrows.

As soon as the voice fell, on his right side, a black shadow appeared silently, it was Chen Mengmeng!

Tang Yan turned his head to look, and his face suddenly showed surprise.

If the previous Chen Mengmeng was a dark elf, blending into the darkness and no one could find out, then the current Chen Mengmeng may have to add another title, a nightmare of the day!

It stands to reason that in the daytime, there is an extra black shadow, which is extremely conspicuous.

But at this time, Chen Mengmeng was standing there, but she didn't have any sense of disobedience, she was like the shadow of a stone, or the shadow of a small grass, making people subconsciously ignore the past.

Even Tang Yan was in a trance for a moment, this was a very terrifying feeling, if Chen Mengmeng tried his best to hide it and suddenly made a move, even if he didn't pay attention, he would probably be injured.

And Chen Mengmeng's strength is also clear, the middle of the congenital!

Chen Mengmeng not only broke through the innate realm, but also crossed the early stage in one fell swoop, reaching the middle stage, this kind of strength leap, even Tang Yan couldn't help but smack his tongue, you must know that he is only the peak of the middle congenital stage now.

At this time, Chen Mengmeng's usually cold face also had a slight smile, obviously very satisfied with this breakthrough.

"The dark power that envelops the Spirit Crystal Vein has been absorbed by me, and now I should be able to invoke the aura of the Spirit Crystal Vein." Chen Mengmeng said.

Tang Yan also felt that there was a pure aura under the ground that was slightly agitated, and his face couldn't help but show joy.

If nothing else, the elixir playground is one of the foundations on which he will stand firm in the future, and there is no room for sloppiness.

The earth-based power on his body surged, and Tang Yan had already burrowed into the ground and came to the place where the spirit crystal vein was.

When he saw the spirit crystal veins in front of him clearly, he couldn't help but open his mouth slightly.

Before, he had a package of dark power, and he could only briefly investigate the scale of the spirit crystal vein, and the answer he got was that it was at least a small spirit crystal vein, but when the dark power disappeared, when he looked again, he found that his guess was wrong, very wrong!

Where is this small spirit crystal vein? It's a large spirit crystal vein!

Everywhere the mind goes, it stretches for thousands of meters!

The extremely rich aura made his breathing shortened.

Get rich in an instant!

Tang Yan almost didn't jump.

A large spirit crystal vein is comparable to the foundation of a first-class sect, if this is spread out, those ancient sects will probably not be able to help but come and snatch it.

"It seems that the elixir playground is going to be built ahead of schedule."

Thinking of this, even Tang Yan couldn't help but get excited.

He took out a seal from his bosom, came to the large spirit crystal vein, and pressed it down in front of him.

Suddenly, this seal seemed to be attached to the spirit crystal vein, and it could no longer be taken off.

At the same time, a bright light began to shine on the seal, and after a while, it was like talking about the little sun.

Tang Yan once again exerted the power of the earth system, and after a while, he came to the top of the back mountain.

At this time, the entire back mountain is quietly undergoing earth-shaking changes!

I saw that layers of smoke slowly appeared on the back mountain, and small fog whirlpools were blown around from time to time.

These are no ordinary smoke, but pure aura!

The invisible aura actually turned into smoke, which was enough to see the intensity of this aura.

Seeing this, Tang Yan couldn't help but smile on his face, the seal he placed in the Spirit Crystal Vein was the eye of the Spirit Gathering Array, and at this time, the Spirit Gathering Great Array had already begun to continuously increase the aura of the Spirit Crystal Vein.

With the control of the Great Spirit Gathering Array, the aura cannot be leaked out, and it directly acts on the back mountain, which is why such a scene is caused.

Whoosh ......

At this time, several sounds of breaking the air sounded.

I saw that the old village chief and Uncle Grassroots and others all came to his side.

Feeling the richness of the aura around them, they all grew their mouths slightly.

They were sure that even in ancient times, it would be impossible to have such an aura, right?

"Xiao Yan, are these spiritual qi from the spirit crystal veins underground?" Second grandfather Tang San asked with some excitement.

Tang Yan smiled and nodded.

"With this kind of aura, isn't that spirit crystal vein medium-sized?" Grandma Zhang's tone was also excited.

Hearing this, Tang Yan shook his head slightly.

Everyone looked at each other and felt a little pity.

"Okay, even if it's a small spirit crystal vein, these elixirs will be effective within ten years." The old village chief said with a smile.

However......

"I didn't say it was a small spirit vein." A voice sounded slowly.

But it was Tang Yan who suddenly spoke.

Everyone was a little stunned when they saw Tang Yan with a smile on his face and the excitement on his face that couldn't be concealed.

It's not a medium-sized spirit crystal vein, it's not a small spirit crystal vein, could it be an ultra-small spirit crystal vein?

That's impossible, it's impossible for an ultra-small spirit crystal vein to have such a rich aura.

"Is it still a large spirit crystal vein?" Uncle Grassroots said jokingly.

Everyone couldn't help but laugh, how is this possible?

But when they saw Tang Yan's undiminished smiling face, they were stunned again one by one.

Immediately, his eyes widened suddenly, and his eyes were full of incredulity!

"Xiao Yan, is it... Could it be that this spirit crystal vein ......"

At this moment, even though the old village chief and the others were used to seeing strong winds and waves, their voices trembled uncontrollably.

But seeing Tang Yan nodding with a smile, he said with great certainty: "That's right, this is indeed a large spirit crystal vein!" ”

Hiss [ fo]......

Hearing this, everyone gasped.

All the surrounding spiritual energy was inhaled into their bodies, and a short vacuum environment was formed!

It's because the news is so shocking!
