Hearing this, the monster did not dare to say more, because he knew that his life was now in the other party's hands, and he had no initiative at all. Therefore, he directly said, "I can upgrade the weapon systems of the mechs you brought, making their shells more powerful. Besides that, I can also enhance their defense, strengthening their ability to withstand attacks. This way, the overall combat power of these mechs will be greatly increased, bringing you much more benefit than killing me. Although the treasures opened from the treasure chest are very strong, they are highly random. Moreover, the treasure chests from monsters of my level are very high-grade, but there are not many items that can directly improve you. You might very well open useless items. Therefore, directly improving the combat capabilities of these mechs is beneficial to both of us. I can keep my life, and you can improve your overall combat power. Everyone benefits, so why not?"
Hearing this, Qin Feng asked doubtfully, "How much combat power can you increase these mechs by, and how much can their defense be increased?"
The monster explained, "I can increase their defense by 20% and their attack power by 30%. In other words, after my modification, the overall strength of these mechs can be increased by about 25%. This is already a very good improvement. Considering the vast number of your mechs, the overall improvement for you will be very considerable. It's much better than killing me and getting a useless item."
Hearing this, Qin Feng sneered and said, "For me, there is no treasure that is useless; they are all very useful. Killing you will also bring me a significant level increase, which is what I need. This is more cost-effective than increasing the combat power of these mechs by 25%. I think I'd better kill you!"
Hearing this, the monster immediately added, "Level increases have no direct use. Only by reaching an integer multiple of 100 can you get a treasure chest, and the items opened from the treasure chest are also random and cannot directly increase your combat power. They are essentially useless. My improvement to these mechs' combat power is a tangible benefit. You gain a lot, so why not cooperate with me? Why insist on killing me? Don't think I only have powerful attack power; my defense is not something you can easily shake. Even if you want to kill me, you will need to expend a lot of effort, and I am confident that I can take a few others down with me before I die. At least half of your mechs will lose their combat effectiveness. Even if you get generous rewards then, it will not be proportional to your losses. Isn't cooperation better? Are you really forcing me?"
Hearing this, Qin Feng explained, "That's right, killing you is part of my plan. If you could directly double the strength of these mechs, I might consider cooperating with you. But since you can't do that, you are essentially useless to me. Killing you directly for experience and treasure chests is more cost-effective."
Hearing this, the mech-type monster knew that the negotiation had completely broken down. They had no common value, no common interests, and now it was a matter of life and death! Therefore, he immediately stood up, raised his mech's power to the maximum, and pushed his defense to the limit. He looked at Qin Feng and said, "In that case, it's still unknown who will win. I wonder if you have the ability to break through my powerful defense. If not, I will kill your mechs one by one. Even if you have special abilities that can block my powerful shell attacks, I believe it will consume a lot of energy from those items. Eventually, when your energy runs out, you will still die in my hands. Ignorant alien, today I will show you the true power of our formidable mechs! Whether you can kill me as you say?"
After saying this, the mech was enveloped in a layer of blue light all over its body, which looked very solid, as if it had added a thick layer of armor. Qin Feng sensed the change in the other party and knew that this battle might last for some time, and he might suffer some losses. But for him, all this was unimportant. As long as he could kill the other party and know how much experience and how many levels the monster in the Level 7 Spiritual Qi Gathering Ground could add to him, it would be worth it. Even if some remote-controlled mechs were consumed, it couldn't be helped. When faced with such a situation, he could not back down.
So, he directly drew his Peerless Good Sword and used the Sword Control Technique to attack the opponent. Golden sword light descended from the sky and struck the mech monster, emitting a metallic sound. However, as the mech had said, when it pushed its power to the limit and raised its defense to the maximum, it was very difficult for Qin Feng's current Sword Control Technique to break through its defense.
The most powerful aspect of the Sword Control Technique was perfect defense, which converted one's own power into defense, making it impregnable. However, Qin Feng did not have a method to convert it into attack. He could only rely on his own strength and the sharpness of the Sword Control Technique to engage in a head-on confrontation with the mech.
Qin Feng knew that as long as he remained undefeated, he could continuously consume the opponent's energy. Even if he couldn't shatter the opponent's armor, he could win as the mech's energy was depleted, although it would waste some of his time. At the same time, Qin Feng also commanded his remote-controlled mechs to form battle formations and launch shells of various attributes to attack the mech. The depths of the cave echoed with the roar of shells and the clash of metal, which were the sounds of Qin Feng and his remote-controlled mechs launching a full-force offensive. The mech-type monster did not attack proactively; it used all its strength for defense, making it impossible to spare any power for a counterattack. It could only endure all of Qin Feng's attacks, hoping that the opponent's energy would be depleted and they would retreat voluntarily, thus allowing it to survive.
At the same time, the mech-type monster also understood that the defender's power was beyond its ability to break through. Even if it converted its power into attack, it could not kill these intruders. Since attacking was a waste of its strength, it was better to convert all of it into defense and force the opponent to retreat.
Thus, the battle entered a stalemate. With the combined effect of shells of various attributes, the power of the armor-piercing rounds gradually became evident. The sharpness of the Sword Control Technique and its powerful attack also yielded some results. The mech-type monster before them had already sustained varying degrees of damage. Although there were no fatal wounds yet, if the attack continued like this, victory was within reach.
The monster also realized this and said, "Stop attacking. If you continue to attack me like this, I will choose to self-destruct. Even if I can't kill you, I will make you pay a heavy price. If we cooperate now, I can enhance these mechs of yours to an even greater extent. Even if I can't double their combat power, it's still better than having these mechs completely scrapped. If you continue to push me, I will unleash my full power and turn all the mechs you lead into scrap metal. Even if you win then, what does it matter to me?"
