Qin Feng never expected that a super Red Alert soldier who had cultivated body-refining techniques would die before his eyes in such a bizarre manner without him even noticing the monster's attack.
There was only one explanation for this situation: the opponent's power was known for its strangeness. In reality, the opponent had attacked long ago, but he hadn't perceived it. Recalling the cave, the deeper he went, the colder it became, yet when he saw the monster, it was unusually warm. Qin Feng understood the key to why the super Red Alert soldier died in such a peculiar way. It must have been on the path they had previously traversed, enduring too much ice power, to the point where the meridians throughout his body were frozen.
Even though the super Red Alert soldier's physique was already stronger than steel, he was still unable to remain intact in such low temperatures. Simultaneously, after seeing the monster's figure, the temperature inside the cave rose sharply, leading to an attack on the super Red Alert soldier's body by two extreme forces, ice and fire, causing it to shatter. It was like a piece of hard rock becoming incredibly fragile when subjected to frost and flames.
The opponent didn't need to make a move because the monster had already sensed that the super Red Alert soldier was on the verge of collapse. This peculiar method of the opponent was likely a special ability possessed by that mecha. The opponent could freely control the surrounding temperature to kill enemies. Before the enemy could even approach, they had already suffered heavy casualties. Ordinary people couldn't get close to this monster at all. Even those with high cultivation would become very fragile under the repeated assault of extreme temperatures and eventually die at his hands.
Even Qin Feng's super Red Alert soldiers, with their robust physiques, couldn't withstand such extreme temperatures, let alone ordinary cultivators.
With Qin Feng's strength, although he was more powerful than the super Red Alert soldiers, his physique was much weaker. If he entered that cave, he might face the same predicament.
Thinking of this, Qin Feng knew that to completely kill the monster in this Level 5 spiritual energy gathering place, he had to prevent the opponent from using their special abilities. The opponent was hidden inside the cave, and the cave was so deep that it greatly preserved the temperature, allowing the mecha's power to be unleashed. If he leveled this mountain peak and destroyed that long tunnel, the opponent might not be able to use such formidable special abilities. Without the assistance of temperature, he could easily approach the opponent, giving him a significant chance of victory.
With this thought, Qin Feng no longer hesitated. He took out the excavation machinery from his storage ring again, handed it to the surrounding Red Alert legions, and ordered them to start working to level the mountain peak, removing the monster's geographical advantage.
He had employed similar methods many times before, and each time it had been successful. As long as he lured the monster out of the secret realm and deprived it of its terrain advantage, he would have a chance to defeat the monster, and his casualties would be much lower.
Thus, the super Red Alert soldiers began operating the machinery to flatten the mountain.
As the sound of machinery echoed, the mountain visibly and rapidly lowered. The super Red Alert soldiers were not only individually powerful but also adept at operating these machines. In a short time, they had already leveled half of the mountain. However, as they continued to dig deeper, they suddenly encountered strong resistance. The machinery couldn't dig any further because they had hit permafrost.
The extremely low temperature caused the rocks to be exceptionally hard, and ordinary machinery couldn't dig through them, immediately slowing down their progress.
Qin Feng sensed this unusual situation. He immediately purchased drill bits from the shop and instructed the super Red Alert soldiers to use these drill bits to bore holes in the hard permafrost to counteract the hardness of the rocks.
Although the speed was still slow, they were digging downwards bit by bit. Qin Feng believed that if they continued with this method, it wouldn't take long to level the mountain.
At that time, it would be his turn to face the monster head-on.
In this manner, the mountain's surface level gradually decreased, and the difficulty of excavating the mountain became increasingly greater. This was because the deeper they dug, the lower the temperature would become, and the higher the hardness of the rocks would be.
Qin Feng estimated that at this pace, it might take him another half a day to completely level the mountain. If killing a monster in a Level 5 spiritual energy gathering place was this arduous, he wondered if it was worth it.
If the experience gained from this monster wasn't substantial, it would be better to spend this time killing monsters in Level 4 spiritual energy gathering places, as those monsters were very easy for him. He could easily defeat them and gain experience, whereas this monster in the Level 5 spiritual energy gathering place carried significant risks and uncertainties.
However, the decision depended on the experience and level boost this monster would provide, as well as the mysterious treasure chest and the treasures it might contain. If the treasures were of high value and his level increased rapidly, even wasting half a day would be worthwhile. Conversely, it wouldn't be worth it, and he might have to avoid monsters in Level 5 spiritual energy gathering places in the future.
He would rather spend more time and energy on monsters in Level 4 or Level 6 spiritual energy gathering places.
If it still wasn't cost-effective, he might have to use the teleportation array to return to the cultivation world to increase his strength, reaching the Mahayana stage cultivation as soon as possible, and then return. At that point, monsters in Level 5 spiritual energy gathering places would be very simple for him, and he could easily kill them to gain experience.
Qin Feng looked forward to facing the monster in this Level 5 spiritual energy gathering place head-on, and he had made some preparations to prevent excessive casualties. He bought a set of cold-weather clothing for each super Red Alert soldier. These clothes were inexpensive because they didn't directly enhance combat power; the prices of such daily necessities were almost negligible.
However, for extremely cold weather, these cold-weather clothes could be life-saving. Even in extreme cold, they could greatly ensure that his combat effectiveness wouldn't decrease too much. Even if they suddenly encountered extreme heat, under the combined attack of alternating hot and cold, they could ensure they wouldn't die immediately and wouldn't suffer the same fate as the previous Red Alert soldier whose body had shattered.
Thus, each Red Alert soldier put on cold-weather clothing. Although they looked a bit bulky, it didn't hinder the movements of these super Red Alert soldiers.
Six hours passed in this manner, and the mountain was finally leveled.
The monster inside also sensed the commotion outside, and the ground began to tremble. The monster was coming out of the secret realm.
