After this incident, the days passed peacefully, and another month went by in the blink of an eye.

On the lush green grass, Lin Ruo sat by the freshwater pool in the space, a fishing rod beside her feet. The rod trembled constantly, indicating that a fish had taken the bait, but she paid no attention to it. She simply leaned back in the lounge chair, closed her eyes, and listened to the rushing water. Ripples could be faintly seen in the surrounding air, indicating that the surrounding energy was gathering towards her. This energy quickly entered her body and slowly replenished the energy that had been depleted within her.

After more than a month of continuous experimentation, she finally found the most suitable cultivation method after the upgrade. Whenever there was a deficiency in the energy within her body, when she entered the space, the energy in the space would flow into her body to replenish the energy deficiency. The greater the deficiency, the faster the process.

So now she trains outside to exhaust her superpowers before entering the space. Every time this happens, an energy vortex appears in the space, directly pouring energy into her body, which also increases her mental strength.

Since the appearance of the mental crystal core in her mind, her mental power cultivation speed has increased significantly. Each time her mental power is overdrawn, the increase in mental power is more than double that before. With the addition of the space's enhancement to mental power, her current daily increase in mental power is equivalent to the results of the previous three days.

Once the energy in her body was replenished and the energy in the air returned to normal, Lin Ruo slowly opened her eyes, sat up straight, and stretched. The renewed energy made her feel very comfortable.

This method is not only effective, but it also saves her a lot of crystal nuclei.

Only then did she look at the fishing rod at her feet. The fishing rod was completely black and crystal clear. She had specially made the rod body out of black jade crystal. The fishing line was made from the spider silk of the level three mutated spiders she had collected before. It was very strong and could even catch mutated fish without any problem. How could ordinary fish in this freshwater pond possibly break free? Once hooked, they would definitely not be able to escape.

The fishing rod is no longer moving, presumably the fish below has given up struggling. She reached out and lifted the rod, wanting to see who today's lucky one would be.

As the water surface glided, a 5-pound carp emerged, its tail twitching weakly every now and then. It looked incredibly plump. She smiled and said, "We'll have braised carp for lunch today."

With a flick of her hand, she removed the resigned carp from the hook, and with a thought, she left the space.

Before she could even carry the fish to the kitchen, she seemed to sense something and looked up at the sky. An unfamiliar fighter jet was flying towards her mountain. The mutated plants around the mountain immediately stretched out their branches to intercept it, but because they were of low level, the distance the branches could extend was limited, with the highest reaching only about 6 kilometers.

The fighter jet had already flown at an altitude of over 8,000 meters, and in the end, these mutated plants could only let the fighter jet fly into the mountain area.

Behind this fighter jet, there were two more fighter jets from the B City base, which were intercepting the fighter jet in front.

"Listen up, fighter jets ahead! This is a no-fly zone. Return to base immediately, or we will open fire to intercept you." A voice came from the fighter jets at the B City base, which were closely following the aircraft.

The fighter jets ahead completely ignored them and continued flying towards the center of the mountain, even increasing their altitude.

At this moment, the three fighter jets had already exceeded 10,000 meters in altitude. The mutated plants in the mutated forest outside the fortress also stretched out their branches to block them. Their strength was much greater than that of the mutated plants outside. Their long branches danced in the wind, waiting for the fighter jets to approach.

Lin Ruo lowered her head and said to A Liu, who was frantically swaying her willow branches beside her, "A Liu, knock it down."

As soon as Lin Ruo finished speaking, A Liu's willow branches immediately surged wildly towards the fighter jet. Since A Liu upgraded to level eight, it had never stretched its branches to their fullest extent, and had no idea how long they could stretch.

But now its branches are heading straight for the incoming fighter jet, quickly breaking through the ten-kilometer distance, and are almost in front of the fighter jet before it even gets close to the fortress's range.

The fighter jet had initially seen the elongated branches, but it was unexpected that the branches of the mutated plant could extend so high. Then a thick willow branch appeared out of nowhere, startling the superhuman on board. The jet continued to climb. Because the fighter jet was made entirely of underground mineral materials, it was heavier than those metal ones. The jet, which could originally fly meters, could now only fly meters high.

This is the current altitude limit for fighter jets, but it's not A-Liu's.

As the fighter jet ascended, Ah Liu's willow branches stretched out even faster, moving at an astonishing speed, until they were almost touching the jet's face in the blink of an eye.

Before the fighter jet could turn around, the thick, long branch lashed out at it, the impact causing the aircraft to shake violently. The bulletproof glass shattered instantly, and the next second, the jet emitted a large amount of black smoke.

"What on earth is this thing? How can it grow so tall!"

"Quickly, we need to make an emergency landing!"

Before they could even react, Ah Liu's second willow branch had already struck the fighter jet. The jet plummeted vertically downwards like a tennis ball being hit, with large areas of the fuselage dented and it completely out of control.

Ah Liu always obeys her master. If her master says to take it down, then she will take it down directly!

The battle lasted less than two seconds before the outcome was decided. The superhumans on the two fighter jets from the B City base behind were terrified and quickly maneuvered their jets to circle in the air, moving away from the mountain area as fast as possible, fearing that Ah Liu would come up and give them a beating as well.

Previously, they had only been threatened by A-Liu, but nothing had ever happened on this mountain. They thought these mutated plants could only dominate the low-altitude range. Now, facing the terror of these mutated plants, they realized that every branch of the mutated plants around the fortress could reach this high.

Not to mention A-Liu, who managed to shoot down the fighter jet when it was at least ten kilometers away from the fortress. They were all covered in cold sweat.

The people inside the crashing fighter jet felt the speed at which the plane was falling and knew that they could no longer refuse, so they simply prepared to jump out.

A dozen people jumped off the plane like dumplings being dropped into a pot, but before they could even deploy their parachutes, they were entangled in Ah Liu's branches.

Unable to move, they used their supernatural abilities to attack Ah Liu's willow branches, only to find that no matter what method they used, the branches binding them were indestructible and could not be shaken at all.

"What the hell is this thing? It's not even afraid of superpowers!" Those who were entangled were still struggling.

The more they struggled, the tighter the branches bound them, as if trying to strangle them.

"This is Lin Ruo's strength. She hasn't even made a move yet. If they had known this would happen, they would have been more friendly."

The person who fell from the fighter jet was in a state of oxygen deprivation, and his mind was blank, with only this one sentence repeating on and on.
