To prevent such an incident, Qin Feng slowly retreated. The beam of light followed him like a shadow. Simultaneously, several other gun muzzles fired bullets of different attributes. Some were extremely fast and powerful, striking the sword screen and causing massive fluctuations in Qin Feng's internal energy.
Others attached themselves to the sword screen like trackers, not attacking but guiding the red laser. This red laser attacked Qin Feng's sword screen like a leech. No matter how far he retreated, the red laser remained a shadow. Even more terrifying was that the laser could turn. Even after Qin Feng had retreated over a hundred meters and made several turns, the laser could still follow.
Qin Feng could sense that the blue mecha had not followed, but the laser seemed to possess a life of its own. Within the winding cave, it tightly pursued Qin Feng's sword screen, as if it would not rest until the sword screen was burned through. Even when Qin Feng retreated another hundred meters, the laser could still follow. What was more frightening was that the laser's power did not weaken with increased distance; its power remained constant.
Qin Feng found it difficult to cope. He calculated that if this laser continued to follow his sword screen, with his current strength, he could maintain it for at most half an hour. The cost of the mecha firing this laser was very low. He could sense that the energy fluctuations on the blue mecha's surface were not significant. Firing this red laser would not cause the opponent's energy to deplete. If this continued, by the time Qin Feng's stamina was exhausted, the opponent might not have even used 10% of their strength.
The opponent's consumption was much lower than his. In this battle of attrition, he was the weaker party.
However, Qin Feng understood that the reason for this situation must be the special bullet attached to the sword screen. Otherwise, the laser would not turn, nor could it sense his location. Although the blue mecha was powerful, there was no reason for it to perceive his every move.
After all, his speed was far more agile and faster than that mecha. If he didn't have a tracking device on him, this laser wouldn't be able to keep up. However, Qin Feng wasn't in a hurry to shoot down the tracking bullet. What he wanted to test was the opponent's maximum attack range. He had already retreated 300 meters from the blue mecha, and the laser could still keep up. This indicated that 300 meters was not the opponent's attack limit. He wanted to continue retreating until he tested the opponent's attack limit.
Thus, when Qin Feng retreated to 400 meters, there was still no effect. When Qin Feng retreated to 500 meters, the laser suddenly weakened. When Qin Feng retreated to 600 meters, the laser disappeared.
However, at the same time, Qin Feng sensed that the mecha had stood up and was moving rapidly towards him, seemingly unwilling to interrupt this attack. It wanted to break through Qin Feng's perfect defense and kill him.
Sensing the opponent's killing intent, Qin Feng commanded the red mecha and retreated with it out of the cave and out of the secret realm.
Qin Feng was very clear about the monsters in the secret realm. Once he left the secret realm, without a target, the opponent would return to its original location. No monster in any secret realm could leave it. Monsters seemed to have a certain obsession with the secret realm, or some special restriction that prevented them from leaving.
Unless he leveled the entire mountain, then the monsters in the secret realm would have no choice but to fight on the open ground. Other than that, the opponent would not come out.
This time, Qin Feng lost a significant amount of his stamina and sacrificed a super Red Alert soldier, but he gained a lot of useful information.
If he could defeat this blue mecha, kill the monster inside, and obtain this blue mecha, he would still profit greatly. Most importantly, the blue mecha's attack power was quite strong. Obtaining it would significantly increase his overall combat strength.
At the same time, he also obtained the mecha's attack limit, which was 600 meters. As long as he entered the secret realm again and commanded the red mecha to stop at a distance of 600 meters from the opponent, and then activated his temperature control ability, he would be able to defeat this monster.
Thinking of this, Qin Feng took a deep breath, then entered the secret realm again. He also commanded the red mecha to enter the secret realm.
This time, Qin Feng was very careful. Before entering the secret realm, he had already deployed the sword screen around his body. This was because once he entered the secret realm, if the monster was close to the cave entrance, he might be attacked. To be safe, he let his sword energy leak out, ready to unleash perfect defense at any time.
However, when he entered the secret realm, he found that the blue mecha had returned to its original position and was not nearby. Qin Feng was relieved. At the same time, he looked at his peerless good sword and found a blue bullet on the sword tip. This blue bullet had a weak energy fluctuation. Qin Feng understood that this was the tracker, and with its existence, the opponent could sense his location.
Therefore, Qin Feng did not hesitate to slice this sensor into two pieces, causing it to disappear completely. Then, he commanded the red mecha to move forward. The two of them walked side by side towards the depths of the cave. When Qin Feng sensed that the monster in the secret realm was hiding in its place without any movement, Qin Feng was finally relieved.
He could see that the monster's intelligence was relatively low. Judging from the previous attack, the opponent probably didn't take him seriously, because he only had the ability to defend and not to counterattack. The monster knew that it was no match for him and might not come again. Even if it entered here again, he would have absolute certainty of victory. Therefore, it hid in its place, unwilling to move, waiting for him to deliver himself obediently.
The opponent's intelligence was at most 5 years old. It didn't realize at all that his previous attack was just a probe. But this was good, Qin Feng could save a lot of effort to subdue this blue mecha and kill the monster inside.
Thus, when the two were 600 meters apart, Qin Feng stopped and pushed backward. He commanded the red mecha to use its temperature control ability to freeze the entire path ahead.
The red mecha's energy rotated rapidly, simultaneously releasing unparalleled freezing power.
The blue mecha, located 600 meters deep, sensed the abnormality because the temperature at its current location was rapidly decreasing. It already sensed that operating this mecha had become difficult. It didn't understand what was happening.
However, it knew very well that its blue mecha was becoming increasingly difficult to operate. Many precise instruments had malfunctioned, and its body had become very cold. If it continued to stay inside this blue mecha, it might freeze to death. But it was impossible to operate the blue mecha to move. The blue mecha had already been frozen.
The only thing it could do was to fire bullets, attacking randomly, using the kinetic energy of the bullets to heat its mecha and restore it to a normal state.
Therefore, the gun muzzles on the blue mecha continuously fired bullets of various attributes to break free from the frozen state. At the same time, Qin Feng had quietly crept up to this location.
He sensed the blue mecha's chaotic state and quietly entered the secret chamber, preparing to deliver a fatal blow to the opponent.
Seeing the opponent firing bullets randomly, Qin Feng smiled slightly, drew his peerless good sword, aimed at the blue mecha's back, and thrust it forward, directly killing the monster inside.
