After getting the Colorful Divine Dragon, Ning Yuan wiped the beads of sweat from his forehead and continued to walk forward, and when the fog that blocked his vision disappeared again, a huge black mountain appeared in front of him.

Nine days of resting on the mountain

The only natural wonder, the peak of the mountain of Siyang, a black earth mountain full of life energy but without any life, settles near the Nine Heavens Siyang Mountain, and can earn a little scientific research value every day.

Nine Layers of Soil: Nine terraced areas of the Nine Heavenly Soil Mountains are distributed from bottom to top, each of which can be artificially planted with a variety of plants.

The first area: doubling the yield and doubling the growth cycle.

The second area: the yield is doubled, and the growth cycle is shortened by a factor of two.

The third area: the yield is doubled, and the growth cycle is shortened by a factor of three.

The fourth area: a two-fold increase in yield and a four-fold shortening of the growth cycle.

The fifth area: a twofold increase in yields and a five-fold shortening of the growth cycle.

The sixth area: a two-fold increase in yields and a six-fold shortening of the growth cycle.

Seventh area: Fourfold increase in yield and sevenfold shortening of the growth cycle.

The eighth zone: a fourfold increase in yield and an eightfold shortening of the growth cycle.

Ninth area: Fourfold increase in yield and ninefold shortening of the growth cycle.

Golden Soil: A special product of Jiutian Xiyang Mountain, it produces one grain per month, and after use, it can transform one square kilometer of land into the first area of Jiutian Xiyang Mountain, and the transformation period is 100 years.

Black Gold Soil: A special product of Jiutian Xiyang Mountain, it produces one grain per year, and after use, it can transform one square kilometer of land into the fourth area of Jiutian Xiyang Mountain, which can be permanently transformed.

When he saw the name of the Nine Heavens Resting Soil, Ning Yuan's first feeling was that he seemed to have heard others mention the Resting Soil, but because too much time had passed, he couldn't remember it. (Well, I can't remember it, I haven't flipped it for a long time)

However, after he finished reading the attributes of the Nine Heavens Resting Soil Mountain, he already knew how to use this treasure land, and he had even thought about who to give it to use, so he didn't bother to bother with that brain cell.

To put it bluntly, Jiutian Xiyang Mountain is a plant cultivation base, which is divided into nine areas from bottom to top, that is, nine layers of terraced fields.

The closer to the terraces at the top of the hill, the shorter the period for cultivating plants and the higher the yield.

Considering that the area of each terrace is limited after all, it is not suitable for planting some ordinary plants, because it would be a waste.

Such a precious land, only those rarest and most precious medicinal herbs are worthy of being planted on it, otherwise it will be a tyrannical thing.

Ning Yuan had obtained a lot of precious pills before, such as black jade intermittent ointment and severed limb regeneration pill and other prescriptions with high strategic value.

However, because the medicinal materials used to refine those pills were not suitable for cultivation on ordinary land, those pills could not be mass-produced.

And after having the Nine Heavens Rest Soil Mountain, this problem can be easily solved, and Ning Yuan can completely hand over the entire mountain peak to Zhao Wendi to take care of, turning this place into a medicinal herb planting base.

Although a Nine Heavens Resting Soil Mountain could not meet Ning Yuan's request for the large-scale popularization of some precious pills, its other two outputs could perfectly solve this problem.

A grain of gold can artificially create one square kilometer of the first heaviest area of the Nine Heavens Soil Mountain.

Twelve grains a year is twelve square kilometers, one square kilometer is about one and a half acres, and twelve square kilometers is eighteen acres of land.

Although the first area of eighteen acres a year is not very much, it adds up to a lot, and with the accumulation of time, there will definitely be more and more fertile land.

As for the period of 100 years, it can be completely ignored, after all, one and a half acres of land can continue to be fertile for a hundred years.

A single grain of black gold soil can artificially create the fourth area of the Nine Heavenly Soil Mountains of one square kilometer, and it is also permanent.

Although it can only produce one and a half acres of land in a year, it is better than permanent transformation.

Ning Yuan may not see the time for the large-scale popularization of the fourth region, but if this game continues to run independently, it will be considered to benefit future generations.

Although the Nine Heavens Rest Mountain could not directly enhance the strength of the Condor Empire, its appearance could allow the regular army of the Condor Empire to maintain a strong combat effectiveness all the time.

When the Amputated Limb Regeneration Pill can be popularized in the army on a large scale, those elite soldiers will not be forced to retire because of the problem of disability, and at the same time, Ning Yuan will no longer need to transform a large number of disabled soldiers into vampires.

Although the vampire is very powerful, the blood clan on the Lost Continent is Ning Yuan's predecessor.

Vampires have a near-infinite life, but they also have distinct strengths and weaknesses.

They were afraid of the sun and were unable to do productive work during the day, and at night, when the other races were resting, it was even more unsuitable for them to go out to work, so they had to rely on others to provide for them, which is also very much in keeping with their name.

The Bloodline on the Lost Continent had spent a lot of resources in their territory to feed the countless vampires in the Dark Temple, so that they could no longer move forward when they reached a certain level.

In the early stages, vampires did help them gain a lot of territory, but as the number of vampires grew, when they could no longer expand outward, those vampires were simply sucking their blood.

It can be said that they grew because of those vampires, and their demise was also because of those vampires.

The reason why Ning Yuan vigorously developed the Vampire Legion in the past was entirely because he did not have an air force under his command at that time, and he was a war maniac who often went out to invade, resulting in a large number of disabled soldiers in the territory.

He converted vampires in large numbers at that time, both to solve the problem of disabled soldiers and to strengthen the strength of his army.

After all, at that time, he made enemies everywhere, and many people wanted to kill him, and he had no choice at all.

And now it's different.

Now Ning Yuan has the powerful Griffin Legion in hand-to-hand combat, the Silver Pegasus Knights who give all enemies a headache, the Air-to-Air invincible Dragon Eagle Knights, and the Seraphic Legion as a killer weapon.

These air forces are enough for the Condor Empire to dominate in air combat, and with the original hundreds of thousands of vampire legions, the scale of the Condor Empire's air force is strong enough.

So after thinking about how to use the Nine Heavens Rest Mountain, Ning Yuan secretly decided not to increase the size of the vampire legion.

In order to prevent the vampire tail from falling out, he plans to stop the production of the Blood Source Pill as well, so that the people of the Blood Clan can continue to choose how to face life and death according to their traditions.

Anyway, after having the ginseng fruit tree, even if they don't transform into vampires, those people of the blood clan can live for a thousand years.

As for those vampires that already existed, Ning Yuan could only choose to continue to support them, after all, they had also made great contributions to the Condor Empire, and without them, there would be no current Condor Empire.

After writing down everything he thought of in a small notebook, Ning Yuan looked up at the colorful divine dragon and asked politely: "Senior, is the soil produced on this mountain for so many years still there?" ”

Although that perverted dragon was shameless, it was still honest, so Ning Yuan didn't plan to waste time climbing the mountain.

"Well..., are those little golden and black grains of earth?

When I'm bored, the pebbles pop out.

What do you want?

I'll see how many are left?

Well, and three more black ones, give them to you. ”

The Colorful Divine Dragon didn't know where to take out three black balls the size of eggs, and then handed them to Ning Yuan very generously.

"Senior, are there any natural wonders on this island that have not been spoiled by you?"

Seeing that the Nine Heavens Rest Mountains had not escaped the poisonous hands of the perverted dragon, the green tendons on Ning Yuan's forehead jumped up again.

The ginseng fruit is edible, and the metamorphosis eats it, but this soil can't be eaten, but I didn't expect that it still couldn't escape the poisonous hands of the metamorphosis dragon, it's really infuriating.

"I took the tree and the things on the mountain, and I didn't touch anything else." The Colorful Divine Dragon explained with a straight face.

Just when Ning Yuan was relieved when he heard this, he suddenly grinned and continued: "Because there is a pool, a tree, a mountain and a stone monument on the island, hahahahahahaha. ”

After being placed by the metamorphosis dragon, Ning Yuan was so angry that he greeted the eighth generation ancestor of the metamorphosis dragon in his heart, and walked towards the last divine dragon stele over and over again.

He really can't afford to mess with this uncle, he just wants to activate the Shenlong Stone Tablet as soon as possible, and then leave this ghost place as soon as possible, if he can, he doesn't want to come over again.
