Mu Gan looked left and right, and after about half an hour, he detected a little bit of the situation.

Underneath the medicine field, there is indeed a passage.

It's just that the entrance to this passage is a kilometer away.

This is one of the reasons why the shepherd has spent so much time.

"I want to see what's down there. ”

Mu Ganxin secretly said in his heart, and then slowly drilled into the passage.

The passage is small and can only accommodate one person.

For Mu Ganxin, it is just right.

As soon as I entered the passage, a hot air rose up.

Mu Ganxin felt extremely hot.

However, because he was so curious, he had to go up and find out.

One step, two steps, three steps, Mu Ganxin was very fast, and he had already gone deep into the position under the medicine field.

What caught his eye was a pool of crystalline energy.

"Oh my God, it's a lot of energy, could it be because of these energies that the medicine field grows so fast?"

Even with Mu Gan's knowledge, he couldn't help but exclaim.

This is really amazing for him.

He had never seen such a rich pool of energy.

The top of the energy pool is like a patch of ice crystals, which is extremely strange.

"It's hot outside, but it's very cool here, like fire and ice. ”

Mu Ganxin said secretly in his heart.

However, to his surprise, the passage did not end there, and it continued to spread......

"Go check it out. ”

Since Mu Ganxin himself is an adventurous person who likes to explore treasures, he naturally will not easily miss the opportunity.

After adjusting his mentality slightly, Mu was willing to take a big step forward.

In any case, he had found a strange place, and he had to go down to see what was going on.

As the pastoral heart continues to deepen, the temperature is getting higher and higher.

The clothes behind him were already soaked.

However, the shepherd willingly ignored it.

In front of Tanbao, nothing can stop him.

Not much.

Shepherd has appeared at the end of the passage.

I saw that at the end, there was a corpse.

This corpse has been dead for a long time.

Mu Ganxin raised his eyebrows, and there were some doubts in his heart.

It's strange that this person in front of him deliberately dug a long passage, and then let himself die in this way.

Beside this skeleton, there are two boxes.

There should be something left there from this person's life, and Mu Gan carefully reached out and took it.

The box was already covered with dust.

With a gentle blow, Mu Ganxin then opened it.

"Ancient Heaven Swallowing Technique?"

Mu Ganxin looked at the scroll of exercises, and his heart was slightly shocked.

This is an extremely domineering exercise, which is rumored to be able to directly swallow other people's lifelong cultivation, and then transform it into one's own energy.

"This master, could it be the Ancient Saint Venerable? Yes, it must be the Ancient Saint Venerable. ”

Mu Ganxin exhaled secretly.

In the previous life, Mu Ganxin was one of the Nine Great Saints, and in addition to Dao Feiyang and Murong Zixian, this Ancient Saint Venerable was one of them.

Of course, Mu Ganxin had never seen this strong man with the same name as him.

"I didn't expect to end up here. ”

Mu Ganxin exhaled lightly.

The Ancient Saint Venerable likes to be alone, and his temperament is relatively withdrawn, so he has not received half an apprentice in his life.

"It's cheaper for me. Mu Gan put this volume of the Ancient Heaven Swallowing Recipe into the spirit ring.

Then, his gaze fell on another black box again.

Mu Gan opened it, and suddenly there was a fragrant smell, which quickly diffused.

It's an elixir.

Moreover, under this elixir, there is also a letter pasted on it.

This letter is carved with spiritual power, so it can be kept for a long time without any problems.

"When you see this letter, I am already dead, my primeval saint is dead, you are very lucky, you are destined. This is a 'Heaven Swallowing Pill' that took my life's energy to refine. ”

"What? is this the 'Heaven Swallowing Pill'?!"

Seeing the elixir in his hand, Mu Ganxin gasped.

"Oh my God, isn't it true that no one has been able to successfully refine the Heaven Swallowing Pill?

Mu Ganxin was surprised.

As an alchemist, he naturally knew what the Heaven Swallowing Pill represented.

It is rumored that it can be completely devoured by one plane!

This is a terrible elixir.

Of course, the pill is terrifying, but his success rate is even lower than that of a frighteningly low one.

Since ancient times, no one has ever succeeded in refining it.

"Ancient Saint Venerable, if I'm not mistaken, he's just an amateur alchemist, right?"

"It's really surprising, I actually refined all the 'Heaven Swallowing Pills', fortunately I got it, if it is obtained by the people of the demon race or the barbarian race, then the human warrior will be defeated without a fight. ”

Mu Ganxin breathed a sigh of relief.

At the same time, he also felt admiration for such a crazy behavior of the Ancient Saint Venerable.

In other words, he probably doesn't have the courage to use his life's energy to refine a pill.

"If I'm guessing wrong, the Jingtian and energy pools outside must have been inadvertently left by the Ancient Saint Venerable. ”

"It should be the waste medicinal materials for refining the Heaven Swallowing Pill. ”

Mu Ganxin suddenly cried and laughed.

The things that the primeval saint didn't need, after a hundred years, had grown into incomparably rare medicinal herbs.

"Haha, this trip is a big reward. ”

Mu Gan laughed.

He then withdrew from this place and buried the Ancient Lord here for all eternity.

It wasn't until it was filled up to the energy pool that Mu Ganxin stopped.

"This energy pool can't be taken away. I'll just set up a branch here, so that I can cultivate more rare medicinal herbs. ”

Mu Ganxin muttered to himself.

Subsequently, he withdrew.

And this hidden passage will be sealed again.

If someone breaks in by mistake and wreaks havoc, it will be a waste of such a good energy pool.

With this energy pool, the growth rate of rare medicinal materials will be dozens of times faster.

This is an endless amount of wealth, and if it is not used well, it will be a bit of a tyrannical thing.

After taking another look, Mu Ganxin suddenly flew back towards the base camp of the True Martial Arts Society.

Returning to the Zhenwu Society, Mu Gan began to build a branch.

Within the True Martial Society, there are also many alchemists.

Mu Ganxin planned to transfer these alchemists over so that they could have more medicinal materials to use, and they could also cultivate more medicinal materials.

Of course, some necessary protection manpower is still required.
