Luo Yuan stood on the branch and looked up at the sky, lost his mind for a long time.

However, there was nothing to see in the sky except the stars, and everything he saw tonight had a huge impact on his soul, and everything was like a dream.

After a long while, he came back to his senses, walked back to the cave numbly, and moved the boulder away, Wang Shishi was still asleep, snoring softly, he didn't sleep all night, but there was no sleepiness on his face, he leaned on Wang Shishi, and sat on the bear skin in a daze,

He felt he needed to be still.

What is the purpose of extraterrestrial civilizations coming to Earth?

Whether it was a simple scientific expedition, or a preparation to conquer the earth, a strange visitor or a pure enemy, or even whether the crazy mutation of animals and plants in the past few years had anything to do with it, nothing is known.

Luo Yuan didn't know if the reconstruction area or the only remaining civilization forces of mankind had noticed this group of extraterrestrial forces, but the possibility was very small.

It is more than 600 kilometers away from the reconstruction area, it is completely the sphere of influence of mutant beasts, it is a forbidden area for human activities, and even high-altitude unmanned reconnaissance aircraft rarely haunt it, not to mention that the behavior of this unknown extraterrestrial civilization is quite cautious, the activity time is in the middle of the night, and the probability of finding it is pitiful.

As for the possible spaceship in space, for the vastness of space, if you want to find it, it is not easier than finding a specific piece of sand in the sea, just hiding behind the moon, or stationed in the planetary belt, with the level of human technology, you can't find it at all.

What's more, the strength shown by this extraterrestrial civilization is far stronger than that of the earth, just like the radar in World War II, there is no solution in the face of the current stealth aircraft, even if the spacecraft appears in the atmosphere outside the earth, I am afraid it will be difficult to find.

Today's reconstruction area is very powerful, the explosion of science and technology, so that the strength of the reconstruction area is growing day by day, although the population is now less than one-tenth of the pre-apocalypse, if you talk about conventional military power, it is more than ten times stronger than before the apocalypse, but in fact, the battle between humans and mutant beasts has always been stalemate, falling into a certain balance, mutant beasts can not advance an inch, and human beings are also powerless to recover their homeland.

The battle is not only on the front line, but also deep into the hinterland, which is an all-round war, from the sky, land, and underground, to the mutant beasts as large as mountains, and the small flies, mosquitoes, and bacteria that breed in the cities. The entire reconstruction area is like an island in the sea, with strong waves on the outside and torrential rain on the inside, and once a certain balance is broken, it will be like dominoes, and it will immediately fall into the danger of capsizing.

However, now there are many extraterrestrial civilizations with unknown friends and foes......

The more he thought about it, the more pessimistic Luo Yuan became, and the future of mankind seemed to be overshadowed.

……

The sky gradually brightened, Luo Yuan rubbed his face vigorously, exhaled a breath of turbidity, seventeen points of will, let him quickly control his negative emotions, no matter what the future holds, life will go on.

"Brother Luo, you're up." Master Wang woke up, sat up and stretched.

"Well, eat something, and after breakfast, we'll go." Luo Yuan said, looking at Master Wang's sleepy-eyed and ignorant look, ignorance is a blessing, at least you don't have to bear this heavy pressure.

Last night's dinner, there was still some left, except that the barbecue meat was already hard like a stone, and the insect eggs could still be eaten, and the two of them simply ate some breakfast and went on the road again.

The cool morning is the most comfortable time of the day, when the high temperature has dropped, the breeze blows on the body, and I feel that the whole pore is breathing, because of the fog last night, the ground seems a little damp, walking in the forest, from time to time there are water droplets dripping down.

However, the water droplets have not fallen, they were suspended in the air by an invisible force, after a day's rest, Wang Shishi was in good spirits, and the fatigue of last night had all recovered, and he still had the spare strength to control the water droplets while following the hurry, entertaining himself.

The air here has gradually taken on a salty and damp smell, the sea is not far from here, and after half an hour, the road can already be seen from time to time with mossy and vine remnants of concrete, but other than these, there is no trace of human civilization.

If it weren't for the coordinates showing that this is already Mushi County, I am afraid it is hard to believe that this primeval forest was a city with a population of more than 200,000 a few years ago.

Luo Yuan flew into the air, discerned, and continued to walk forward.

Waist Mountain is thirty or forty kilometers away from Mushi County, people are extremely rare, there are no people in a radius of several miles, there is no road except a dirt road to reach before the end of the world, and now there is no road, only by the naked eye to distinguish.

On the map, you can't find the name Waist Mountain at all, just a humble peak in a rolling mountain range that no one knows except the locals.

Compared with the pre-apocalyptic times, there are basically barren mountains here, sparse plants, and even bare mountains at all, and now the plants are all over the place, the size is huge, and the plants that move at a height of 100 meters undoubtedly greatly increase this difficulty.

If you want to find it, you can only follow the waterfall.

This is not difficult, Luo Yuan's keen ears have already heard the rumbling waterfall, but the migration that the wanderer said was half a year ago, when the sea level rise had just begun, and it was still in an arid zone.

And now, judging from the salty smell in the air, this place has become a coast, the climate is humid, the rainfall is abundant, and this is a mountainous area, the terrain drop is very large, and the waterfall is no longer rare, and there are seven or eight waterfalls heard in the distance.

But luckily, it's just a matter of time.

Luo Yuan searched everywhere, and when it was close to noon, he came to the fifth mountain with a waterfall, just a look, Luo Yuan's eyes lit up, this mountain is not high, the drop is about three or four hundred meters, the strange shape is the shape, the mountainside is slightly concave, if you remove the plants, lose weight, it looks completely like the "waist mountain" that the wanderer said.

A waterfall sloped down from the bottom of the mountain, and fell suddenly, it was a waterfall formed by the breaking of an underground river, the water volume of the waterfall was not abundant, the drop was not high, and the waterfall in the vicinity was inconspicuous, so that Luo Yuan did not find this place until now.

Luo Yuan left Master Wang in place, after all, the front is not safe, he can scare the Hui people into fleeing in a hurry, and the people who move the clan are at least sixth-level creatures, sixth-level creatures are okay, he can easily deal with them, what he is most afraid of is encountering seventh-level, such a huge thing, even if it is just a pounce and a jump, it can cause large-scale destruction, once encountered, even he can only go all out, and he can no longer take care of Master Wang when fighting.

He carried a horse chopping knife and went on the road lightly, the mountain road here was rugged and extremely steep, and several man-eating vines that looked like living creatures spread quietly like snakes, trying to attack, but were cut off by Luo Yuan one by one.

A few huge man-eating flowers bloomed in the shade of the trees, with bursts of sweet fragrance and bursts of sweet fragrance, and the neighborhood was already full of dry bones.

Not far away, a giant plant up to 100 meters tall is moving slowly, with each step, the roots as thick as a giant python pull out of the ground, or poke into the ground, causing the earth to shake, the trunk is full of cracks of the "old" bark combined into a huge fuzzy human face, as it walks, the expression changes slightly.

It seems that most of the plants here have become animalistic, and the rare tree people have found three in just a few kilometers.

Luo Yuan slapped a bloodthirsty mosquito away, and listened to the louder and louder waterfall, his speed suddenly accelerated.

In a few minutes, Luo Yuan lightly jumped onto a boulder, and there was already a waterfall in front of him.

The terrain here is relatively flat, the ground is covered with large and small oval stones, the drop of the waterfall is only more than ten meters, falling down the deep pool below, and finally forming a river more than ten meters wide, meandering into the valley bottom along this rocky beach.

The strange thing is that the plants here are quite sparse and much smaller, with only a few trees growing on this rocky beach at a glance, and there are very few vigorous vines and weeds.

And the strange plant near the pond that is fifty or sixty meters tall obviously stands out from the crowd under this low "shrub".

The bulbous roots, the sarcoma-like bumps, the sparse leaves, the twisted towel-like trunk, and the baby's skull-sized fruit all indicate its identity.

"Wisdom Tree"

Luo Yuan's eyes lit up, and his breathing was a little short.

This tree of wisdom was much larger and thicker than the one found before, and its color had also changed, the previous one had a yellow and purple trunk, and this one was already completely purple, even a little black, and seemed to be filled with blood.

The level of this wisdom tree is significantly higher than the original one!

But although he was anxious, Luo Yuan did not act rashly, he looked around carefully, there were no creatures nearby, even the insects and birds in the ordinary forest seemed to have disappeared, which was extremely abnormal.

Feeling carefully in the air, there seemed to be a faint depression remaining, which made Luo Yuan's brows furrow slightly.

He hesitated, then pressed the hilt of the knife and walked slowly, while his perception expanded to the limit, carefully searching for nearby movements, but he didn't feel anything wrong at all, and as he walked in, his perception soon covered the waterhole.

Originally, I thought that the mutant beast was in a waterhole, but it turned out that I didn't notice it at all.

The waterhole is not deep, only three or four meters, and the radius is only a hundred meters, and there is no dark hole at the bottom, except for a group of "small fish" several meters long swimming in the water, there is nothing.

In the last days, a creature of this size can only be called a small fish.

Luo Yuan breathed a sigh of relief, it seemed to be a false alarm, the mutant beast that was originally here might have died, or had already left this place, in the jungle, the weak eat the strong, extremely cruel, even if the mutant beast is powerful, it will encounter accidents if you are not careful.

However, the bones under the wisdom tree are a little weird, and I didn't care about it when I looked at it from a distance, but it felt strange to be nearby at this time, Luo Yuan found that each of these bones was extremely large, and even one of the thigh bones lying on the ground was about ten meters long, and the thickness was one and a half meters, like a huge stone pillar, and it fell on the bones obliquely, which was several circles larger than the soul eater beast that Luo Yuan had seen before, and such slightly smaller bones nearby were everywhere.

Forget one or two, but here are all such bones, piled up near the Wisdom Tree, the entire sea of bones, forty or fifty meters thick, occupying tens of thousands of square meters, Luo Yuan noticed that the bones in the ground have turned into gray-white bone powder, and he doesn't know how many powerful mutant beasts are buried here.

He suddenly felt a little uneasy in his heart, this sea of bones could not be done by the Hui Clan, with this bone, even any mutant beast could wipe out the Hui Clan.

At this time, he vaguely smelled a trace of blood, he sniffed lightly, keenly looked at a certain place in the sea of bones, and suddenly his face changed greatly, and countless translucent filaments grew from the trunk of the Wisdom Tree, like a cocoon, firmly wrapped one of them.

The corpse was apparently quite "fresh", and it happened not long ago, maybe even yesterday.

His heart became heavier and heavier, this mutant beast didn't leave at all, but went to hunt for food in the distance, and with his own strength, he formed this sea of bones where a considerable part of them were all seventh-level mutant beasts, and it was definitely not an ordinary seventh-level mutant beast, and it was probably even eighth-level.

He glanced at the tree of wisdom not far away, hesitated for a moment, then moved, jumped a few times, and stood beside the trunk, not daring to drag it any longer, God knows, when this terrifying creature will come back.

He pulled out the chopping knife, and the one-meter-long knife was violently swallowed in the air, and in an instant, the knife light was like a long rainbow through the sun, and it flashed away, and then his body exploded back, and there was a loud bang, and as the huge trunk fell, the thick trunk, like a giant python that turned over, began to roll violently.

A large number of bones flew in the air, and the fierce wind blew the nearby trees to fall one after another. Like cold dripping into the boiling oil, the sea of bones was stirred into a pot of thick porridge, and a series of explosions occurred, like rolling thunder, these tree trunks were half a meter small, and one or two meters thick, and the number was thousands, and even the sky was obscured under the fierce tumbling and shaking. The Wisdom Tree's movements before its death were comparable to a raging seventh-level mutant beast.

As time passed, Luo Yuan walked around in the distance, looking anxious, but he could only wait patiently.

The Wisdom Fruit is basically useless to him, and what is useful is the "Wisdom Heart".

However, the conditions under which the "Wisdom Heart" is formed are quite harsh, and only when the Wisdom Tree suffers irreversible damage will most of the nutrients shrink from the trunk to a certain core of the tree.

This is equivalent to a seed, and when the crisis is over, this seed will take root and sprout again on the original corpse through the nutrients gathered, and it will be revitalized again, which is the survival method of the Wisdom Tree.

But this takes a certain amount of time, and no matter how anxious Luo Yuan is, he can only wait patiently for it to automatically activate this protection mechanism.
