After only two or three days of travel, Lin Chen walked for more than ten days.

The time wasted was naturally all spent on killing spirit beasts and cultivating gluttonous techniques.

In the past ten days, as many as fifteen second-grade spirit beasts were killed by Lin Chen, and there was also one third-grade spirit beast with low strength.

The benefits brought to him by sixteen spirit beasts were undoubtedly not low, as early as three days ago, when the third-grade spirit beasts were halfway through eating, Lin Chen had successfully broken through to the early stage of the Yellow Rank Eightfold.

Coupled with the spirit beasts that have been eaten in the past three days, they have now reached the middle stage of the Yellow Rank Eightfold.

This increase in speed, even a genius like Lin Yi has to bow down to the ground.

The biggest hero must be gluttonous.

The nine-grade exercises are worthy of the nine-grade exercises. This speed increase is terrifying.

There were still more than thirty kilometers to the top of the mountain, Lin Chen stopped, he had already arrived at the final destination of this trip, the Lin family's Wind Spirit Tree Area.

Lingyun City is named after Lingyun Mountain, and the major families of Lingyun City also rely on the resources of Lingyun Mountain to rise. The Lin family, as one of the veteran families in Lingyun City, is naturally even more so.

The Wind Spirit Tree is a first-grade spiritual material, and the grade is not very high, but the effect is not bad. Sun-dried as firewood, the effect is comparable to the real fire of second-grade alchemists and refiners.

In particular, the few roots at the very top of the Wind Spirit Tree's roots, if used as firewood, can even reach the level of the Five Grades True Fire.

A small amount of wind spirit wood may not be worth much, but if it is a large amount of wind spirit wood, the value is definitely not bad. Especially for those sects or families that focus on alchemy and refining, materials similar to wind spirit wood are absolutely essential.

Because the wind spirit wood can save true fire for alchemists and refiners, it can also allow low-grade alchemists and refiners to refine slightly higher-grade elixirs and spiritual weapons without corresponding grade true fire.

Of course, low-grade alchemists and refiners refining elixirs and spiritual weapons that are higher than their own grade must have a very low success rate. But the experience gained is not comparable to refining those low-grade elixirs and spiritual weapons every day.

The Lin family's Wind Spirit Tree Area covers an area of about 200 acres, and there are as many as 3,000 Wind Spirit Trees cultivated in it.

It was with this Wind Spirit Tree that the Lin family could grow stronger and stronger and become one of the old families in Lingyun City.

In order to protect this Wind Spirit Tree area, the price paid by the Lin family was also extremely huge. Whether it was the attack of the spirit beasts in the mountains or the coveting of other families, the Lin family had a double-digit number of clansmen killed every year due to this Wind Spirit Tree area.

"How do you get in?"

Looking at the direction of the Wind Spirit Tree Area from afar, Lin Chen touched his chin and pondered with his eyebrows.

As the most important property of the Lin family, the Wind Spirit Tree District not only built a three-meter-high wall with huge stones, but also heavily guarded it. The outlying sentries alone are as many as 100 people a day.

If you want to sneak in quietly, even if Lin Chen has reached the Yellow Rank Eightfold, it is still extremely difficult.

Swaggering in, don't even think about it.

Although Lin Chen is also a member of the Lin clan, and he has a hall master father, he does not have a token issued by the family, and once he gets close, he will immediately be besieged.

"Use the "Friends" and "Sweep" functions to find out the preferences of the director of the Wind Spirit Tree District, and then do what he likes, and find a way to let him take him into the Wind Spirit Tree District?"

As soon as this idea came out, Lin Chen vetoed it.

Over the centuries, the Lin family has formed a routine. The people who can become the directors of the Wind Spirit Tree District are all the iron-faced and selfless, upright and irritable masters of the family.

This kind of person, even if he can do what he likes, it is difficult for him to make an exception and bring himself into the Wind Spirit Tree area.

"Find a way to lure a third-grade spirit beast over? and then sneak in while there's chaos?"

Lin Chen frowned, but still shook his head to extinguish this thought.

The strength of the three-grade spirit beast is between the ordinary yellow-rank nine-fold to the Xuan-level three-fold martial artist, he has the function of "sweeping", and can know the fatal shortcomings of the spirit beast, as long as he does not encounter the top-level third-grade spirit beast, he has the power to fight.

The various traps, traps, and guard forces arranged by the family in the Wind Spirit Tree area, although it is not difficult to kill a third-grade spirit beast, even in the face of the top-level third-grade spirit beast, even if it can't be killed, it is not a problem to repel it. But the price paid is not low.

Dozens of people are killed and injured in the family every year, and half of them are because of the occasional scurrying spirit beast accidentally entering the Wind Spirit Tree area.

After all, he is also a member of the Lin family, although he has no sense of belonging, and he has not done anything to harm the interests of the family. But this kind of indirect murder of innocent people, Lin Chen still can't do it.

"That's right! No matter how tight the outposts are, there are always traces to follow. If we can find out the exact location of these secret sentinels, it shouldn't be difficult to sneak in!"

Lin Chen suddenly slapped his thigh, and finally had an idea.

For others, it is difficult to find out the distribution of the dark whistles on the periphery of the Wind Spirit Tree area, but for Lin Chen, with the function of "Friends", this is not a problem at all, and it just takes a little more time.

Calling up the "Friends" function, Lin Chen immediately began to search.

After making sure that there were no secret sentinels within a radius of two hundred meters, he immediately headed towards the Wind Spirit Tree area.

Once the existence of the Dark Sentry is discovered, they use the search to deduce the location of the Dark Sentry and bypass him to move on.

Going deeper and deeper, although it took more than ten times the time to search for the secret sentinel and avoid traps and traps, Lin Chen was getting closer to the wall step by step.

After more than two hours, Lin Chen finally came to the outside of the wall.

After making sure that there were no guards inside the wall, Lin Chen jumped over, directly climbed over the wall, and successfully entered the Wind Spirit Tree area.

With a breath of turbidity, Lin Chen headed towards the center of the Wind Spirit Tree area. Along the way, there are yellow fallen leaves everywhere. The Wind Spirit Tree, which is supposed to be evergreen and leafy all year round, has bare branches and no green leaves. And there are small black spots scattered on it, which is extremely ugly.

At a glance, the wind spirit trees that are more than ten meters high, as if they have entered the old age of the wind candle, are all lying on their bodies, crumbling, making people have the illusion of falling down with a push.

"It's only been half a month, and it's become so serious?"

Lin Chen felt that something was wrong, this was simply terminally ill!

If it is really too late to be treated, the news spreads again, and the entire Lin family will face a catastrophe.

Even if the news did not spread, once the family's inventory of wind spirit wood was exhausted, the Lin family would also fall into a serious state of making ends meet.

There are no eggs under the nest, the family has suffered heavy losses or even annihilation, and no one in the clan can escape the catastrophe, including him and Cheap Daddy. Because other families will never give the Lin family any chance to rise and take revenge, but anyone with a little ability and status will definitely not be able to escape the hunt.

After really seeing the desolation of the Wind Spirit Tree District, what Lin Chen was thinking about was no longer how to save the cheap father's powerful position by saving the Wind Spirit Tree.

The Lin family is in ruins, not to mention the elders, even if it is the patriarch, it is not bullshit.

This Wind Spirit Tree must be healed.

Without any hesitation, he first searched the distance of the nearby guards, and then Lin Chen called up the "Sweep" function, selected the first sub-function, and aimed the camera at the Wind Spirit Tree.

Wind Spirit Tree: A spiritual material

Advantages: It can be used as fuel for alchemy and refining, and the top part of the root is used as fuel, and the effect is comparable to that of the five-grade true fire. It grows fast and is easy to preserve.

Disadvantages: It can survive in a low temperature environment, and it needs red loess with extremely high phosphorus, potassium and iron content to grow.

Lin Chen was silent, the Wind Spirit Tree was the lifeblood of the Lin family, and all the habits and information about the Wind Spirit Tree had been studied and recorded by the family. The relevant information is clear to the Lin clan.

As a member of the Lin family, Lin Chen is naturally clear.

The information displayed by the "Sweep" function, except for what the red loess is made of, the rest, Lin Chen already knew.

"The reason for the decay of the Wind Spirit Tree must be inseparable from the soil, insects and temperature. ”

"The temperature was normal and negligible. Moth-eaten words...... The family must have suspected this reason, and it has not been solved for a long time, indicating that it has little to do with insect moth. In that case, the soil problem remains. ”

"If it's a soil problem, it's going to be difficult. Red loess is not something that can be found casually, especially in such a large area. If you really want to find a large amount of red loess, the family must have changed it all. ”

Lin Chen suddenly felt a headache, he didn't know how to increase a certain trace element in the soil, so that the soil could turn back into red loess that was conducive to the growth of the Wind Spirit Tree.

"Let's see what is lacking before we figure it out!"

Lin Chen grabbed a handful of dirt casually, called up the "Sweep" function, and deducted it from a WeChat point.

Red loess: a product of spiritual soil

Advantages: The content of phosphorus, potassium and iron is very high, which is conducive to the growth of wind spirit trees.

Disadvantages: It is difficult to form and is not conducive to the survival of other plants.

"Not because of the soil?"

Lin Chen was quite surprised by the results of the sweep, and he tried to grab a handful of soil in a different place again, and the results still showed that it was red loess with extremely high phosphorus, potassium, and iron content.

It took six WeChat points to test six batches of soil in a row, and the results are still the same.

"How?"

Lin Chen was a little dumbfounded, not knowing whether to be happy or depressed.

If it was something else, maybe he could solve it alone. But if it wasn't the soil, what would it be that caused the Wind Spirit Tree to wither?
