My Mysterious Left Hand

Chapter 67 Anti-Fly Runes

Now all that's missing is the ability to distinguish friend from foe.

Li Chen picked up a pen from his desk and started writing and drawing on the paper, but found himself at a loss as to how to use the function that distinguishes friend from foe.

"Then let's set up the interception formation first."

He put down his pen and directly used both hands to form an array, with the source energy constantly evolving between his hands.

Although he is currently unable to unleash his source energy to attack enemies, as if he is being pulled along by invisible threads, manifesting it on his body is not a problem.

Soon, a huge six-pointed star array, half a meter in size, appeared between his hands.

In the center of the hexagram array is a very mysterious pattern resembling a rune.

Wait—this rune—"

A thought struck Li Chen, and he continued to evolve the formation, constantly calculating in his mind. One idea after another surfaced in his mind, and the formation pattern was also changing rapidly.

It's unclear how much time passed, but the formation grew smaller and smaller, simplifying itself until it gradually transformed into a rune.

If I could unleash my source energy now, this rune should theoretically be able to be thrown out, but right now—

He fixed the rune in his right palm, then groped around with his left hand, producing and selling it himself.

[Anti-air attribute +1]

"Anti-fly attribute?"

Li Chen was puzzled. The rune he had deduced should have been an interception rune, similar to a barrier.

Is there some mistake somewhere?

He looked at the runes in his right palm, continuing to simulate and deduce in his mind while continuing to collect the runes.

[Anti-air attribute +1]

[Anti-air attribute +1]

One by one, the anti-air attributes were collected, and the runes' radiance gradually dimmed.

However, during this process, he was also constantly mobilizing source energy to replenish it.

With a constant supply of source energy, this rune can never be completely collected.

Therefore, he continued to produce and sell his own data, and the amount of anti-aircraft attributes he collected increased.

Although this attribute doesn't seem to be very useful for the time being, the palm space can now hold an unlimited number of attributes, so there's no need to worry about it taking up space.

Even if it really takes up space, we can just break it down later.

It's a good opportunity to store up some of the original resources.

Suddenly, Principal Qin Xiaotian's presence appeared.

Li Chen looked up and saw a figure flying over quickly and landing outside the principal's office.

"There's a solution on Earth. Some key passages can block all invaders, but the passages that are still forming need to be destroyed."

As soon as Qin Xiaotian entered, he asked directly, "Do you really possess the ability to destroy the world portal?"

"I have no reason to lie to you," Li Chen replied.

"That's good—hmm? What's that in your hand?"

Qin Xiaotian suddenly looked at the rune in Li Chen's right hand, and his expression changed slightly.

The moment he saw the rune, he felt dizzy.

He tried his best to suppress the dizziness and look at it, but found that he couldn't see the rune at all.

"This is the anti-air rune I developed, but it's still a work in progress."

Li Chen dispelled the array, stood up, and said, "Shall we return to Earth now?"

"Alright, let's go."

Although Qin Xiaotian was very interested in Li Chen's half-finished anti-air rune, Li Chen's breakthrough was also very important.

Therefore, he didn't say much and walked out of the office with Li Chen.

Just as the two were about to head towards the boundary marker, the clear sky outside suddenly darkened.

Immediately afterwards, dark clouds gathered, and a huge thundercloud vortex slowly took shape.

"What's going on?" Li Chen asked, puzzled.

He wasn't using his Thunder Punishment Divine Power right now, and he was quite certain that his Thunder Punishment Divine Power hadn't gone out of control.

"This aura—it means someone has broken through."

Qin Xiaotian's face lit up with joy: "If I'm not mistaken, the vice principal should be advancing to the Cave Heaven Realm."

"Vice Principal Xiong Erkun?"

Li Chen asked in surprise, "Does breaking through to a higher realm require undergoing tribulation?"

"Yes, to break through from the Mortal Realm to the Cave Heaven Realm, one needs to overcome the Heavenly Tribulation."

Qin Xiaotian said happily, "We have very few strong individuals on Earth. It's great that the vice principal has also broken through. With your cultivation speed, you might be able to transcend tribulation soon. Let's go take a look."

"OK."

Li Chen nodded, then took a step and disappeared from the spot.

"This kind of tactic—"

Qin Xiaotian was taken aback, and then quickly took to the air, chasing after the direction in which the thundercloud vortex was moving.

That's right, the thundercloud vortex is moving. This must be because Vice Principal Xiong Erkun is worried that the lightning will damage the city and is shifting its position.

Because he was waiting for Qin Xiaotian, Li Chen walked slowly into the distance, taking only one hundred meters at a time.

Of course, he was traveling on the ground. Even if he could briefly step into the air by teleporting, he would still be in free fall during the teleportation process, so traveling on the ground was still more comfortable.

Before long, the two left the city and traveled to a place ten kilometers away from the city.

Here, they saw a young man adjusting his state on a mountain peak.

"Is he the vice principal?" Li Chen asked.

"Yes, it's him."

Qin Xiaotian replied, "Erkun's talent is not bad either. He only started cultivating three years ago, and in three years, he broke through to the mortal realm. Even on the entire Earth, he can be considered to be in the top tier."

However, this speed is no match for Li Chen's freakish speed.

Li Chen refrained from commenting, lest Qin Xiaotian be discouraged.

He looked up at the lightning that was constantly gathering in the sky, secretly comparing the effects of his lightning punishment divine power.

At this time, some teachers who had not yet returned to Earth or were supposed to be stationed here were also attracted by the strange phenomenon.

"Shouldn't it have started by now?"

"Why hasn't the thunderbolt fallen yet?"

"Is it still gathering strength?"

I could hear the voices of other teachers around me.

Even Qin Xiaotian couldn't help but mutter, "This tribulation lightning has been building up for so long, why hasn't it struck yet?"

"Is there a problem?" Li Chen asked, puzzled.

"Of course there's a problem. The longer the lightning tribulation takes to accumulate power, the greater its power will be."

Qin Xiaotian said with a solemn expression, "Generally speaking, there is at most a minute between the appearance of the tribulation lightning and the first bolt of lightning striking, but three minutes have passed now. It seems we have underestimated the vice principal."

"Could it be that the power of lightning tribulations differs from person to person?" Li Chen asked.

"That's natural."

Qin Xiaotian nodded: "The more talented a person is, the greater the power of the tribulation lightning will be—of course, that's not necessarily true. It also depends on their foundation. The deeper their foundation, the greater the power of the tribulation lightning will be, because this tribulation lightning is a test of the combat power of people at the same level."

"I see." Li Chen suddenly realized.

Qin Xiaotian frowned as he watched the lightning tribulation, which seemed to be still gathering power. Then he looked at Li Chen and said, "You probably need to prepare yourself too. Your foundation is probably beyond our imagination. Your tribulation will definitely be more terrifying."

"I'll be careful," Li Chen nodded.

"Rumble—"

In the sky, thunderclouds swirled continuously, with endless lightning flashing within, as if they could strike at any moment.

But everyone waited and waited, but the thunder just wouldn't fall.

This scene terrified everyone, even Xiong Erkun, who was undergoing tribulation, felt his scalp tingle.

"More than five minutes have passed—"

"Seven minutes have passed —"

"How is this possible? Ten minutes have passed, why hasn't the thunderbolt landed yet?"

Everyone started to get chills.

Under normal circumstances, the time between the appearance of a lightning tribulation and the first bolt of lightning striking is usually only about one minute.

The charging time is longer, possibly two to three minutes.

During this time, those undergoing tribulation can also relocate to a different location to prevent the lightning tribulation from destroying cities or affecting mortals.

However, even for a super genius, the time it takes to accumulate power for a tribulation lightning is generally only about five minutes.

But now, more than ten minutes have passed, and the lightning tribulation still hasn't struck.
