For Song Jian, this task was a bit unexpected, but it was also expected. When the difficulty of the task and the reward of the task were constantly increasing, Song Jian had this hunch.

The reward is often proportional to the difficulty of the task, and if the difficulty of the task suddenly increases, but the reward does not change much, then congratulations, maybe you have encountered a chain of quests or hidden quests.

This kind of task is often hidden very deeply, and it needs to be continuously excavated, but such a task will also be very difficult, and a large number of players who cannot complete this task will be brushed out in the early stage, such as this task, for ordinary players, killing thousands of insect soldiers, just to reward 8%-10% of combat experience, is obviously a very cost-effective thing, with this effort and energy, you can also get experience points beyond the task reward by brushing low-level monsters, and it is much safer than hunting insect soldiers.

Song Jian accepted this task without hesitation, he knew that the difficulty of this task must be much more difficult than hunting thousands of insect soldiers, but from the perspective of task rewards and task punishments, a lot of experience can save Song Jian at least a month or two of effort, and the epic treasure chest, there is a high possibility of obtaining an epic piece of equipment, which is not bad.

"You are a true warrior!" Veteran-soldier Vane exclaimed, "These insect soldiers are the great enemies of mankind and must be strangled!" ”

"We once stormed the nest of these insect soldiers, but we were eventually driven out by them, and that nest is in a cave deep in the valley, and I need you to explore that cave, and when you are done exploring the cave, the mission will give you instructions on what to do!"

When Song Jian heard this, sure enough, he nodded and walked towards the valley.

Entering the valley, Song Jian first used the concealment necklace, entered the stealth state, and then ran all the way to the cave deep in the valley.

At this time, the valley has been filled with insect soldiers again, they are wandering around the valley, even if Song Jian enters the stealth state, he must be careful, otherwise he will be surrounded by insect soldiers if he is not careful, although Song Jian is not afraid of them, but these insect soldiers will delay his progress in completing the task.

It took more than half an hour for Song Jian to finally come to the mission site, at the mouth of this cave deep in the valley, you can see that from the cave there is a steady stream of ordinary sixty-level insect soldiers, they seem to have just hatched, and there is still mucus left on the pitch-black carapace, but after leaving the cave, the wind quickly dissipates in the air.

"This should be similar to a place where the insect soldier production base is located, there must be more powerful insect soldier bosses in it, and there will even be lord-level and dominant-level bosses." Song Jian said secretly in his heart.

The task reward is an epic piece of equipment, and if there is no boss of the corresponding difficulty, I am afraid that Song Jian himself will not believe it.

The entrance of this cave is not large, the diameter is only about five meters, and it can accommodate four or five insect soldiers walking out side by side, Song Jian stared at the entrance of the cave for a while, and found that not every moment there are insect soldiers pouring out of it.

There will be a short gap between one wave of insect soldiers and another wave of insect soldiers rushing out, only about ten seconds, at this time, that is, when he enters the cave, after all, no matter how small the warning range of the insect soldiers is, but the distance is less than one meter past them, they will still be detected.

Soon, Song Jian took advantage of the gap to rush into the cave, and when he entered the cave, he found that this underground area was incomparably vast, and as far as the eye could see, the cave was full of strange rocks, and everywhere was filled with the sharp screams of insect soldiers.

Song Jian dodged the insect soldiers all the way and walked towards the depths of the cave, every once in a while, dozens of insect soldiers would rush out from the depths of the cave and rush towards the valley, such an environment was not suitable for the duel of the large army, once they could not have an overwhelming advantage over the insect soldiers, the battle was dragged into a war of attrition, and defeat was doomed.

In this case, it is suitable for a small number of elite soldiers like Song Jian to enter the cave and carry out exploration and decapitation operations, but in this way, the danger also increases exponentially, after all, the number of insect soldiers in this cave is too much.

Along the way, Song Jian saw a lot of oval-shaped insect eggs that were more than half a person tall, these eggs seemed to be waste eggs, and they had become fossil-like existences, and the surface was covered with a thick layer of rock, which looked like a stone egg.

For these existences that are like stone eggs, Song Jian is also very wary in his heart, and he hides far away all the way.

After wandering in the cave for more than half an hour, Song Jian came to an underground river, in the center of this underground river, there was a small island, on the small island was placed a golden treasure chest, and next to the treasure chest, a body was obviously much stronger and burly than ordinary insect soldiers, wandering around this treasure chest, no matter where it went, its eyes had been staring at this treasure chest.

The golden treasure chest is becoming less and less attractive to Song Jian, but the insect soldier in front of him makes his eyes shine, this is obviously a BOSS, and the strength is not bad, ordinary insect soldiers don't even dare to approach it, and there is only one monster on the entire island.

"Insect Soldier Lord, Level 65, Lord-level BOSS, Qi and Blood 190000/190000"

"Level sixty-five lord-level BOSS......" Song Jian said secretly in his heart.

At this time, he was more than a hundred meters away from the island, and there were a large number of insect soldiers wandering around along the way, if he rushed straight over like this, I am afraid that it would cause the restlessness of the insect soldiers in the entire cave.

Song Jian hid beside a huge rock, holding the Heaven Breaking Sword and staring at the insect soldier lord in the distance, his heart moved, hundreds of spirit swords floated on him, paused for a moment, all the spirit swords moved at the same moment, and flew towards the insect soldier lord in the distance.

The attack range of the Ten Thousand Sword Jue is extremely wide, as long as Song Jian can lock on the monster, the spirit sword can attack, the power of this skill has always been affected by Song Jian's own attributes, and it cannot exert 100% power, otherwise, the legendary sword immortal method of taking the enemy's head for thousands of miles can also be displayed on Song Jian.

The spirit sword flying in the air did not alarm the insect soldiers along the way, only the lord-level boss who was locked by the spirit sword seemed to feel the threat, and his whole body became nervous, constantly looking around, letting out a low roar, and looking restless.

Just when it hesitated, the spirit sword had already slashed at its body, and the moment it was attacked, its hatred was locked on Song Jianjian, who was more than a hundred meters away.

I saw it let out a roar, turned around and rushed towards a winding path, this is the only entrance and exit of the island, only from here can you leave or board the island, if Song Jian chooses to fight in close combat, it is not easy to just get close to this boss.
