The army slowly touched along the "blood vessels", and everyone's nerves were tensed to the extreme.

"Pay attention to your breathing rate, and go back to the ground to rest after three hours if you don't get any results." Alan said.

Ivan nodded, he knew that the army and others were breathing with the oxygen provided by the oxygen cylinder, and once the oxygen was off, the hood had to be removed.

Removing the hood is not the same as death, but it will inhale pheromones in the air, producing hallucinogenic effects, and the consequences are not much better than death from lack of oxygen.

After walking for more than ten minutes, Alan listened attentively to those subtle beating sounds from time to time, and the illusion that appeared in his heart became heavier and heavier.

But those illusions could not confuse his mind, and his internal strength and mental method had been cultivated to the point where he could not be cultivated, and the level of immunity to spiritual interference was very high.

"Maybe I can remove the hood and save oxygen." Alan thought to himself.

He thought to himself, but he didn't remove the hood, because he didn't know if there were other toxic substances in the air, and it wasn't worth the risk.

After walking for a while, the shape and size of the blood vessels on the ground were larger, like the roots of a tree, and the capillary network, chaotic and disorderly.

As the roots of these trees increased, the sound of the heartbeat in the soundproof suit became more and more pronounced, changing from a subtle sizzling sound to the sound of mosquitoes surrounding.

"Your Majesty, there's something ahead!"

Alan also looked intently, and there was a vague red light in front of him, but the white light of the flashlight covered the red pale light, making the red light close to nothing.

"Take the light of the flashlight out of the way, and don't shine in front of you."

The orcs hurriedly moved the light to both sides, and no one used a flashlight to shine in front of them, and the ground in front of them suddenly darkened, and the pitch black once again covered the red "roots" ground.

Three or four hundred meters in front of the ceiling, there was a dim red point of light, like a dark eye, watching them.

"What's that?"

"I don't know, but I seem to see a vision flashing before my eyes, like a tree......" The orc whispered over the intercom.

"Don't listen to those voices carefully, those who see the illusion immediately retreat and operate the inner strength of the heart."

"Your Majesty!" The orc's face was slightly pale, and he hurriedly retreated a few dozen meters, feeling that the voice was a little quieter, and the illusion was not so serious, and then closed his eyes and silently operated his internal strength to expel mental interference.

"It's dangerous ahead, I'll go explore the road first." Alan said in an unquestioning tone.

"Your Majesty, no, it's dangerous!"

"Your Majesty, I didn't see an illusion, let me come!"

The orcs exclaimed again and again, and Alan turned his head and ordered:

"Ivan, pay attention to military discipline, no one is allowed to move without me."

Ivan gritted his teeth, he didn't want His Majesty to take risks, but among all the people present, only Allen's internal strength and heart method were at the highest level, and he had to agree.

"Yes!"

Alan took the gun and slowly approached the area of the giant tree.

The orcs behind him all raised their guns, and once Eren gave the order to fire, they would shoot three or four hundred meters away.

Approaching, Alan saw a huge tree, it was about fifteen meters tall, the trunk was twisted by scarlet veins into a spiral trunk, the upper part of the tree was propped up, and the branches had no leaves, like a dry blood-colored old tree.

Each old branch bears a fruit, and the fruit is bright and dripping, like a drop of water about to fall to the ground, hanging on the branches.

Alan quickly scanned it with a flashlight, and there were about two hundred fruits on the tree.

Because the tree didn't attack him, Eren didn't shoot either, but silently used the full-level identification technique.

[Unknown Ancient Tree]: This is an unknown tree that grows in the ruins, which can absorb heat from the air, and its nutrients are absorbed from the ground and various life elements in the air.

Because the growing body needs more energy and nutrients, it can no longer sustain life, and its life is coming to an end.

Additional Identification: It is a genetically modified organism of a civilization.

After reading these two lines of identification, Alan felt that the information was not sufficient, far from enough.

He wanted to know what the purpose of the ancient tree was, so Alan got closer and closer, so close that he was already a few meters away from the ancient tree.

At a distance of a few meters, if the ancient tree had moved, it should have moved, but the ancient tree did not move.

Scarlet Gu stood on the solid ground, the beating sound was beating like a drum, and a sense of illusion flashed in Allen's mind from time to time, but those mental disturbances were suppressed, and they could not affect Allen's mind.

Alan slowly touched a tree root thicker than his own, his palm was separated by heavy clothing, his gloves touched the soft root, and the drumming in his ears became heavier.

Because of the physical encounter, the two have become more closely connected, and the identification terminology of ancient trees has changed slightly.

"Additional identification 2: Each fruit is a psychedelic tree species, and after being replanted and grown into a seedling, it will have a strong psychic interference ability, and can release continuous sleep brain waves or riot brain waves to animal groups."

With this line of identification, Alan was overjoyed.

He couldn't dig up this ancient tree, after all, its roots were all rooted in the ground and he couldn't move it, but the fruit produced by others was very small, and he could pack it all and take it away.

Alan observed in place for a while, and a rustling sound came from the walkie-talkie, which was the voice of his subordinates: "Your Majesty Allen, are you okay?" ”

"I'm fine." Alan replied, going back, back to the army.

The orcs couldn't help but breathe a sigh of relief when they saw Eren return safely.

Alan consulted with the soldiers for a few minutes, and his subordinates were moved when they learned that the ancient tree had reached the end of its life and that the fruit on the tree could be replanted.

"Your Majesty, let me go and get the fruit, I'm the best at climbing trees." Ivan stood up without hesitation.

"Our clothes are too bulky for climbing trees." Alan shook his head.

"But the branches are too high above the ground for us to climb the trees and pick the fruit." Ivan didn't come up with a good idea either.

"Simple, let's go back to the ground and make a steel rod that can be assembled, with a tree basket at the top, and then tie a dagger to cut off the fruit branches and let the fruit fall into the small basket."

Each fruit is high and low, the low one is nine meters, and the high one is fourteen meters, and it is not realistic to use wood, and the fruit that is so high just now is picked with steel.

After having a goal, the orcs were also satisfied when they returned from the second half of the journey, and they walked with the wind, which was very happy.

The ruins were quiet, there were no genetic creature attacks, no phantom attacks, and the orcs returned safely to the ruins door.

Take off the hood and breathe in the free air, Ivan and other orcs never thought that the air of nature was so sweet.

"After inhaling too much artificial oxygen, I suddenly felt that the air in nature was so pure." The soldier sighed.

Alan smiled and sighed along the way, which resonated with the soldiers.

After sighing, everyone had to go back to the warship and use the oxygen generation tools on the ship to re-produce oxygen.
