The most important factor in the maintenance of an oasis is the vegetation. Pen % fun % Pavilion www.biquge.info

An oasis can only be maintained with a certain amount of vegetation, but the foundation of the oasis vegetation is still water.

An oasis, a gathering place of the Sand tribe, water is the most fundamental and important.

If an oasis loses a sustainable source of water, it is only a matter of time before the vegetation grows larger.

Therefore, what Ye Zhen wanted to do for the Black Sand Tribe before leaving, he fixed on the matter of water sources.

Only after sincerely doing a little bit for the people of the Sand tribe and the people of the Black Sand tribe can Ye Zhen accept the power of their dedication with peace of mind.

This is Ye Zhen's heart and conscience.

The water source of the Black Sand Tribe is actually just an underground river flowing through here, which is the basis for the survival of the Black Sand Tribe.

Water sources are the creation of heaven and earth, and an extremely complex and complete ecological environment is needed to produce a sufficiently stable water source.

Such a thing as giving birth or increasing water sources out of thin air, not to mention Ye Zhen, even the Dao Realm and even the Creation God Man can't do it.

What Ye Zhen can do is to stabilize and expand this underground dark river.

According to the leader of the Black Sand tribe, Heiman, the flow of this underground river, which they call the River of Life, has been reduced by more than half in the past hundred years.

The population of their Black Sand tribe has naturally decreased by half, and the size of the tribe has changed from a medium-sized tribe to a small tribe, in fact, the main reason is that the flow of this river of life has decreased sharply.

The reason for the sharp decline is also very simple, the Idol Green Sacred Tree that protects the underground river is constantly decreasing, the evaporation is increasing, and the loss on the way through it is also greatly aggravated.

For various reasons, the river of life has been sharply reduced.

Ye Zhen set his eyes on this Idol Sacred Tree.

This Wintergreen Sacred Tree is actually just a common evergreen shrub in the Izhi Sand Sea, which can resist the extremely harsh natural environment.

Not to mention extremely drought tolerant, it is also extremely cold-resistant, which is very suitable for the extreme weather in the sand sea.

Moreover, the root system of this Wintergreen Sacred Tree is extremely developed, and the root system is nodulous growth, once it grows on a large scale, those root nodules will spontaneously and tightly tangled together, like the wall of the ground, which can naturally fix sand and retain water.

Before the Izhi Sand Sea Heavenly God was born, this Iholly was only Iholly, not the Iholly Divine Tree of the Sand Sea.

However, in the god-like means of the god of the Izusha Sea, countless seeds of the Idol Tree were sprinkled, so that the developed root nodules of the Imacullys were closely combined in the riverbed and wall of the underground dark river, greatly reducing the loss in the underground dark river.

At the same time, the surface of the dark river is also planted with the Holly Sacred Tree, which can greatly reduce the amount of evaporation, not to mention the amount of evaporation, but also fix the sand and restore the soil.

If a large number of Imaly Sacred Trees have been growing in a sandy area, after decades of growth, the sandy land will be reverted to soil.

Today, the oasis soil of the Izuku Sand Sea is all after the Sand Sea god Izuku planted a large number of Izuku Sacred Trees.

Not only that, the fruit of this Holly Sacred Tree can also squeeze sweet and high-quality oil, which was once the main source of oil and one of the trading goods of the Sha people.

This Wintergreen Sacred Tree is already a divine object for the Sand people, and that kind of love can no longer be described in these two words, it can be said that it is protecting it with all its strength, and a large number of seeds are planted every year.

But that's where the Holly Sacred Tree comes in.

The Ephello Sacred Tree is a sacred object to the Sand people, but its cultivation is very difficult.

Ordinary Sand Tribesmen, if they plant 10,000 seeds of the Idol Sacred Tree, not a single one will sprout.

So far, only the Blue Robe Priest and the Sand Sea God Priest of the Izuku Temple have the ability to plant a live portion of the seeds of the Iholly Sacred Tree.

Like the average blue-robed priest, the germination rate of the seeds he planted for the Idol Tree was only one-tenth, and this was only the germination rate.

This Wintergreen Divine Tree, before its roots penetrate deep into the sandy bottom, is very fragile, maybe a strong wind can blow away countless people.

Therefore, within a month after germination, it was necessary for the blue-robed priests of the Yizhi Temple to continuously perform divine magic to spawn in order for these Idol Sacred Trees to survive.

Normally, if you plant 10,000 seeds of the Immortal Tree and survive 500, it would be remarkable, and only the top blue-robed priests could do it.

Like an ordinary blue-robed priest, it would be good to be able to survive two or three hundred in the end.

The demand for the Iholly Divine Tree in the Izhi Sand Sea is calculated in trillions, and with such a low survival rate, even if the blue-robed priests of the Izhi Temple will use divine magic to plant the Iholly Divine Tree every year, the number of Iholly Divine Trees in the Sand Sea, even if the Sand people use all kinds of strength to protect the Iholly Divine Tree, but all kinds of reasons, artificial, devouring of other living beings, weather reasons, etc., are constantly decreasing.

It is precisely for this reason that this Ilholly is called the Sacred Tree, and in the Izhi Sand Sea, only the magic of the Izhi Heavenly God can plant this Holly in a large area.

Because of this, Ye Zhen put his idea into practice on the Idol Divine Tree.

It can bring benefits to the people of the Sand tribe, and it can bring benefits to Ye Zhen himself, there are not many such choices.

Ye Zhenguan Heiman asked for a bag of seeds from the Wintergreen Divine Tree.

There are so many seeds of this Holly Sacred Tree in the Yizhi Sand Sea that almost every Sand Tribesman hangs it on their chests as a mascot.

The seeds are shriveled and shriveled and don't seem to have the slightest bit of water, and when you bite into one, they crunch like stones.

It is hard to imagine that such a seed can survive if it is planted, but in the induction of Ye Zhen, a martial artist who is proficient in the spiritual power of Otogi, the core of this stone-like seed has an incomparably powerful vitality.

That vitality is sealed, and once activated, it will burst out with an incomparably powerful life force to maintain and protect the oasis here.

He casually threw a few seeds of the Idol Tree into the sand under his feet, and with a movement of his mind, Ye Zhen first used his spiritual power to draw a little water from the ground and send it into the depths of the seeds.

Ye Zhen could sense that the life force in the depths of the seeds of the Iholly Divine Tree was moistened by that little bit of water, and it grew slightly, but it had no intention of germinating at all.

"Is it because there is not enough water?"

Subsequently, Ye Zhen used his divine thoughts to send in more water.

However, something strange happened.

The amount of water that Ye Zhen sent into the seeds of the Wintergreen Divine Tree exceeded the size of its seeds, but the seeds of the Wintergreen Divine Tree still did not show any signs of germination.

Ye Zhen knew that it was definitely not the cause of the moisture.

A sand sea plant, if it needs a large amount of water to germinate, it has long been eliminated by the Great Dao of Heaven and Earth, and it will not be able to survive until now.

"Little demon, do you know what's going on with this kind of thing?" Ye Zhen asked.

After all, the little demon is from a tree demon, and he has the blood of the ancient giant spirit tree demon almost a royal family, so he should know about this situation.

"Father, in order to survive in the harsh environment, this seed of Holly has a self-protection barrier inside its seed, and in order for it to germinate, it must first break this self-protection barrier. The little demon said.

"How to break?" Ye Zhen asked.

"It's very simple, if a little Otogi spiritual power is sent in, the life force inside it can spontaneously grow, and it can break through the barrier of self-protection by itself. ”

With the voice of the little demon, a little bit of Otogi spiritual power was sent by the little demon into the seed of the Immortal Tree of the Wintergreen, and almost instantly, the seed of the Immortal Tree of the Immortal Tree bloomed a little sprout.

Originally, this process would take several days, but at this time, it was sped up by Otogi's spiritual power.

As Ye Zhen used his divine thoughts to send a little bit of water, the root system of the seeds of the Idol Divine Tree began to quickly take root into the ground.

Under the acceleration of Otogi's spiritual power, the nodules began to form rapidly and became one.

The integrated nodules do have a strong water-retaining ability in Ye Zhen's induction, and if it can be controlled to grow near the dark river, the protective effect on the underground dark river will be very powerful.

And after a period of time, the flow of the underground river will increase, because the loss will be reduced.

However, the consumption of such an Imacyhow Divine Tree is not much, very little.

But if you add the demand, it's terrifying.

Ye Zhen calculated, with his current cultivation, it would be good to be able to give birth to 100,000 Eaholly Divine Trees in one day.

And just the Wintergreen Divine Tree that the Black Sand Tribe needs is afraid to be counted in millions or even tens of millions.

"Father, I am a dryad, the king of the ancient giant spirit tree, and I have the call of the ancient spirits, a divine skill that rules over many wood-based creatures.

If I use my power to channel and command their own life force, I can spawn more Wintergreen Sacred Trees with less consumption. The little demon suddenly spoke.

Ye Zhen was overjoyed when he heard this, "How much can it be that day?"

"At least ten times as large as my father, and if I can get the support of my father's power, the number will increase exponentially. The little demon said.

Ye Zhen knew that the little demon was definitely easier than himself in this regard, but he didn't expect that the gap would be so huge.

Now that the problem of this consumption is beginning to be solved.

Ye Zhen immediately began to prepare for the planting of this Idol Holly Divine Tree.

However, the planting of the first batch of Holly Sacred Trees must be planted around and on the surface of the underground Dark River in order to play its huge role.

Therefore, before planting, Ye Zhen needs to be well mapped and prepared.

At the same time, it will take a little time for the Black Sand tribe to prepare millions of seeds for the Idol Tree.

However, with the order of Heiman, the leader of the Black Sand Tribe, the Sand people of the Black Sand Tribe were extremely excited to gather a large number of seeds of the Idol Sacred Tree.

More than 90,000 people from the Black Sand Tribe gathered again, looking at the seeds of the Iholly Divine Tree piled up like a hill with great anticipation, as well as the incarnation of Ye Zhen, the divine envoy of the Izhi Heavenly God that they thought they thought.

But at this moment, Hei Man, the leader of the Black Sand Tribe, looked at the light rushing in the sky, but his face changed.

"Divine envoy, the temple has arrived!"
