Super Invincible Battleship

After this group of ape warriors entered the room, they found that the enemies inside had disappeared. Then they saw the tunnel in the room. So they immediately entered this tunnel, ready to pursue the fleeing Yan Fei and Gu Xiaolan. But shortly after they entered the tunnel, the energy left by Gu Xiaolan in the tunnel exploded violently. This explosion not only destroyed the tunnel but also killed many ape warriors.

Gu Xiaolan had left no stone unturned. When opening the tunnel, she left a backup plan, which successfully got rid of the pursuing enemies behind them. The room they entered was just an ordinary room with no apes present. Gu Xiaolan replicated her method, drilling a new tunnel in the wall with her White Long Sword to quickly leave the room. When they left again, Gu Xiaolan again destroyed the tunnel behind them, leaving no chance for the enemy to pursue.

In a short time, Yan Fei and Gu Xiaolan had advanced ten kilometers deeper into the ape tribe's flagship. During this process, they encountered several waves of blocking ape warriors. However, because their speed was extremely fast, and the ape tribe couldn't transport forces along a shorter path than a straight line, the ape corps commander had no way to gather enough troops to intercept them, allowing them to advance rapidly like a hot knife through butter.

Under Gu Xiaolan's perceptive abilities, even if the ape corps commander set ambushes along their path with heavy troops, these ambushes would immediately be detected by Gu Xiaolan, who would quickly change direction, rendering the ape ambushes ineffective.

The combination of Gu Xiaolan and the White Long Sword was invincible and had enduring stamina. In just a short time, they had penetrated one-hundred kilometers inward, traversing unchallenged.

Then the two of them stopped almost simultaneously. Yan Fei asked in confusion, "Xiaolan, do you feel anything unusual here?"

Gu Xiaolan nodded, saying, "I feel it too. Starting from here, a mysterious energy permeates the surroundings."

Yan Fei said, "I've never encountered this kind of energy before. It is neither technological civilization's energy nor cultivation civilization's dark energy, but I can feel its quality far surpassing other energies."

Gu Xiaolan said, "This energy should be a higher-level energy refined artificially."

Yan Fei looked into the distance and said, "I'm beginning to sense the source of the mutant cosmic rule you mentioned. This mystical energy is emanating from that source. I'm afraid that the source of the mutant rule is not as simple as we imagined."

Gu Xiaolan said, "Since we entered here, I noticed many unreasonable aspects inside the ape flagship. I believe all these unreasonableness are related to that source. If we can destroy that source, we can destroy this ape flagship."

Yan Fei said, "If that's the case, let's keep going!"

So the two continued to advance. The closer they got to the source, the more intense the mutant cosmic rules and mysterious power around them became. An hour later, they had broken through more than half of the steel walls inside the ape flagship and arrived at the place where the source was located. Behind them, countless ape forces had been left far behind. Although these ape forces were desperately pursuing in their direction, they couldn't keep up with their pace.

With Gu Xiaolan's perceptive ability, she had long sensed that more than one hundred thousand ape warriors were gathering near the source. So when exiting the steel walls, she didn't choose to appear directly near the source but instead appeared in another tunnel one kilometer away from the source to avoid stepping directly into an ambush.

But even so, Yan Fei and Gu Xiaolan were immediately spotted by the ambushing ape warriors. A large number of ape warriors rushed towards them, engaging in fierce battle. Gu Xiaolan's choice of location was excellent. This tunnel was very narrow, accommodating no more than ten ape warriors in battle at a time. This prevented the ape warriors from leveraging their numerical advantage and allowed the White Long Sword, separated from Gu Xiaolan, to quickly kill them.

After traversing nearly 500 kilometers of steel walls, Gu Xiaolan's strength seemed unaffected. She remained full of vitality, showing no signs of fatigue. Her Long Sword once again decomposed into a hundred slender swords, which flickered like omens of doom, instantly killing hundreds of ape warriors. No ape warrior could withstand Gu Xiaolan for even a moment. Even the top-tier God-level experts were equally instantly killed by the Long Sword.

Compared with the time at the Holy See Headquarters, Gu Xiaolan has matured a lot and become much stronger. If the current Gu Xiaolan faced the Headless Knight of that time, the Headless Knight would definitely not be Gu Xiaolan's opponent…

The battlefield Gu Xiaolan chose was greatly to her advantage, sparing her from the ape warriors' attacks, while also allowing her to quickly kill large numbers of ape warriors. Ultimately, this resulted in a situation where the ape warriors rushing to intercept them were outnumbered by those being killed by Gu Xiaolan, leaving large gaps in the passage ahead. Yan Fei and Gu Xiaolan quickly advanced along the passage.
