Meng Nan's face suddenly turned pale.

At the moment when the girl woke up just now, a task suddenly appeared in the system in his mind.

"Urgent Mission: Rescue!

Your student strayed into an underground crack in the Grand Canyon of Donglin Mountain, Ji Li led away the insect demon's life and death is unknown, Zhang Su'er is in danger of demon poison, and your mission is to save your student. Mission requirements: Clear the toxins in Zhang Suer's body and save Ji Li who is trapped in the devil's cave. Time limit: three days.

Zhang Su'er, who is highly poisonous in her body, has a heroic righteousness to hang her life, but she can only survive for three days, and only by using the blood flower that grows in the underground world as the main medicine and refining the antidote pill can save her life.

Reward: 1,000 faith points, student gratitude. ”

Unlike the white side quest and the purple main quest that Meng Nan took before, the color of this quest is blood-like crimson, which looks shocking. Meng Nan understood that this meant that 100,000 was in a hurry.

Underground!

Worm Demon!

It's an underground worm demon!

Meng Nan looked at these words, and his heart turned over turbulently.

Speaking of the underground insect demon clan, the first reaction of the martial artists in the Luo Tian Great World is evil, and they will hate it from the bottom of their hearts.

It can be said that the history of human warriors is a history of blood and tears fighting against the underground insect and demon clan.

In the Luo Tian world, there are nine heavens, and the legendary celestial races live in the ninefold heavens.

Humans and other intelligent races live in the vast expanse of the earth.

And at the foot of human life, there is still a dark underground world, here, is the world of the insect demon clan.

The underground and the ground are separated by spatial barriers, and they are like two parallel worlds, which are not related to each other. But I don't know how many thousands of years ago, between the two worlds, countless spatial cracks suddenly appeared, and countless underground life surged to the ground, and after discovering this beautiful and rich surface world, I realized that there was such a wonderful place in this world, so more insect demon people rushed to the ground.

Plunder and destruction are the nature of worms and demons.

More and more underground life is appearing on the surface, trying to conquer the world.

Invasion and protection, the collision of two different civilizations, is destined to break out into a great war.

This was the beginning of a multi-million-year war between the ground and the underground.

Countless heroes, in order to protect this beautiful world, rose in the war, and died in the war, leaving behind countless heroic legends and legendary stories.

The hatred between the two sides has also become deeper and deeper in this war between the past and the present, until they become mortal enemies and can no longer be resolved.

Until a thousand years ago, most of the insect demon clan had been driven back to the ground in the human counterattack, and the spatial cracks that had appeared were also suppressed by the powerful seals among the human warriors, and the war seemed to be over, but no one dared to guarantee that it would break out again.

The ground world is too big and too big, and although the spatial barrier between the two realms is extremely stable, the changes in space are difficult for martial artists to predict. The underground insect demon covets the richness of the ground, and has always been a thief, and in the past thousand years, there will still be small spatial cracks one after another, causing small insect disasters, but the human warriors are extremely vigilant about this situation, and once they find it, they will definitely suppress it with all their strength and seal the cracks. Therefore, there has never been a large-scale invasion of underground life.

Hundreds of years ago, Stardust Academy began to rise in a small insect disaster.

That time, the spatial crack appeared near Stardust Academy, the legend of the academy, the first dean, led all the teachers and students to establish a defensive line to protect desperately, and the teachers and students followed one after another, insisting on not taking half a step back, and lasted for seven days and seven nights until the arrival of reinforcements.

In that battle, the battle was extremely tragic, and the teachers and students of the college died countless deaths.

After the Insect Plague was suppressed, Stardust Academy became famous, and in just a few decades after that, it grew rapidly to become the only high-level academy in Starlight City.

A series of memories surged in Meng Nan's heart, and the information of the Insect Demon Clan also appeared in his mind.

Could it be that on Donglin Mountain, there is a spatial crack again?

You must know that less than ten miles east of Stardust Academy is Donglin Mountain, which stretches for hundreds of miles, if there is really a pest disaster, the academy will definitely bear the brunt!

Meng Nan shuddered at the thought of the endless appearance of countless disgusting giant insects surging towards the academy.

Donglin Mountain Grand Canyon.

Teacher Meng Huo Ran stood up, his eyes becoming extremely determined.

At this time, Zhang Suer, who was lying on the ground, was still unconscious, but her face gradually became calm.

In the dilapidated cultivation ground, more than a dozen teenagers had a worried face, and they were secretly relieved when they saw Zhang Su'er's face improve. Looking at Teacher Meng's eyes, it also became a little complicated.

This person doesn't seem to be as annoying as the teachers before him.

Meng Nan looked at the immature faces in front of him, the incident happened suddenly, and there was a trace of panic in their eyes, and they were a little overwhelmed.

After all, they are all young.

Meng Nan thought for a while, and said in a deep voice: "The one in Su'er is the insect demon poison!"

Worms?

The students were slightly stunned when they heard this, and their faces suddenly changed wildly.

"You say...... Underground insect demons?" Leng Qiufeng, who was almost strangled to death by Teacher Meng just now, asked, his voice trembling a little.

Seeing Meng Nan nodding heavily, all the students invariably swelled up with great fear in their hearts.

"They...... How can you be hurt by worms......?

No one dared to think about it anymore.

Although their qualifications are not good and their behavior is strange, they all know what the word insect demon means.

If it were a bug plague, it would be an unimaginable disaster.

Teacher Meng looked at the students and said in a deep voice: "The matter of the insect demon should not be publicized until it is confirmed. The poison on Su'er's body can't be delayed any longer, with my vitality to protect her heart, it will be fine for the time being, but it can only support for three days at most. We need to find the antidote in these three days. ”

"Students!"

Meng Nan had a serious expression and looked at this group of bad teenagers. The students looked at each other before he continued, "I know you all like to play, okay, now you come and play a game with me." The consequences of this game are very serious, once you lose, you will lose the lives of Ji Li and Su'er!"

All the students were stunned, and then they were furious, Nima, are you still in the mood to play a game at such a critical juncture?

Before they could speak, they heard Teacher Meng continue:

"The poison on Su'er's body can only be completely removed by using the Ghost Blood Flower that grows in the underground world as the main medicine and refining it into an antidote pill. Now, I'm going to Donglin Mountain, and if there is really a spatial crack there, I'll find the Ghost Blood Flower and save Ji Li. Time is urgent, you listen to me, two things. First, let me stay here, and never let anyone move Su'er's body, otherwise I will scatter the vitality I left in Su'er's body, and the demonic poison will kill her immediately. Second, if I can't come back within three days, go to the Danyuan to find Dean Zhang and ask him to help Su'er renew her life. ”

Meng Nan paused and continued: "This game is not fun at all, it is not interesting, and the protagonist is me, you can't participate directly yet. All you have to do is stay calm and wait patiently. ”

"Does anyone know the Donglin Mountain Grand Canyon?"

"I've been. Leng Qiufeng said weakly.

"Trust me, I'll be back!"

After Teacher Meng finished speaking, without waiting for them to react, he had already grabbed the cold autumn wind, turned into a streamer, and rushed out of this dilapidated cultivation ground. Leaving a group of delinquent teenagers, looking at each other.
