After that, the armies of both sides took a break for a few days, and neither the highlands nor the sky rays rashly attacked each other, and the border seemed to be calm again.

However, everyone understands that under this seemingly peaceful façade, there is a more intense storm, and it is not known when it will completely erupt. So with the passage of time, An An is slowly becoming more and more agitated, because he understands that because the country of Heavenly Radiance has an innate terrain disadvantage, and now they are tantamount to being directly exposed to the surveillance of the highlands, so the longer the battle drags on, the more dangerous their situation will be, so An An has to take the initiative to attack, otherwise he can only be led by Bai Li's nose, then the situation is really not good!

So the prototype of a plan gradually took shape in An An's mind, giving him the idea of taking the initiative to attack once.

In the early morning of that day, the mist rolled over the plains, and the fog made it impossible to see what was going on. Taking advantage of the fog, Tianying's soldiers hid under the cover of the fog, and quietly marched towards the cliff on the other side of the highland, in an orderly manner.

Xia Lin, Lin and the others also stayed near An An with solemn faces at this time, paying attention to every move in the vicinity.

"Are you ready?" An An asked, glancing back at Nina beside her.

Nina nodded stiffly and whispered, "You can start." "It seems that even a guy like Nina, who is usually full of confidence, can feel nervous on the battlefield where human lives are at stake.

An An turned around and no longer looked at Nina, but calmly glanced at the troops in front of him, and saw that the time was almost up, so he said, "Let's start." ”

As soon as An An's words fell, a dozen or so soldiers pushed a huge cart to the relatively empty flat ground. On top of the cart was a huge iron object, oddly shaped and quite intricate, making it unclear what it was for.

Berg felt a little uneasy, so he confirmed again: "Are you sure this thing will work?" Ever since he saw the nasty breathing mask, Berg had been skeptical about Nina's level.

"Don't worry, I've done this type of flying machine many times before when I was in Twin Moon City, and I'm very proficient and can't go wrong. Nina rarely got angry because of other people's doubts this time, but explained seriously.

"In that case, let's do it quickly! I think the sentries in the heights have already discovered our whereabouts, and are now in a hurry to report back. If we don't do it, I'm afraid they'll react right away. Berg said.

An An didn't rush to make a move, but looked up at the sky and said, "Don't worry, it's not the time yet, wait a while!"

Berg was a little anxious, so he asked: "Why? We sent troops in the early morning, just to seize the opportunity to attack the high ground by surprise, why did you wait slowly for the high ground to discover our whereabouts, isn't this giving up the advantage to others?"

An An smiled and explained, "Now that the two armies of the Highlands and Tianying are fighting, and the border area is full of scouts and spies, how can we avoid the eyes and ears of the Highlands with so many people gathered in the vicinity of the Misty Forest with such fanfare? The reason why I chose to wait a little longer is to wait until the most opportune time. ”

"When?"

"You'll find out in a moment. ”

At this time, An An ordered the soldiers to take out the huge iron weapon. After removing the straw that covered the transportation on the surface, the appearance of the iron tool was completely presented in front of everyone's eyes. It actually looked familiar, much like the metal ball that Nina had used to determine the composition of the misty in the Misty Forest, but in an enlarged version.

An An saw that the time was ripe, so he ordered someone to start the "iron ball". The "Iron Ball" squeaked a few times and adjusted the internal structure, and then began to rotate slowly.

Gradually, the "iron ball" rotated more and more frequently, and finally it moved directly towards the open space! It circled all the way along the barren ground, and then moved to the vicinity of the section of the hillside, and finally flew directly into the sky, rolling away towards the cliff on the other side of the high ground!

Due to the speed at which the iron ball leaped quickly, it suddenly disappeared from the eyes of the celestial glowing people.

After that, about a minute later, a flash of light suddenly appeared somewhere on the cliff on the other side of the highland! With a strong dazzling light, the mountain shook violently, and even the side where Tianying was located was affected, and the tremor could be felt!

For a long time, there was no movement on the high ground. Layla was a little apprehensive and asked, "How's it going?"

An An pondered for a moment and replied, "Judging from this distance and direction, our plan should have worked. Otherwise, judging from the action of the highland army, it should have already appeared here at this time and was ready to counterattack. ”

It turned out that An An knew that Tianying's weakness was obvious, so in order to be able to win, he had to find another way. Due to their geographical disadvantage, the people of Tianying only knew that the troops of the highlands were stationed on that side of the mountain, but they could not determine exactly where they were stationed. Therefore, An An's preemptive strike this time is actually just a trick.

Before this operation, Tianying had actually made a lot of preparations, and Charlene had cast a potion in the misty forest in the place where the spies in the highlands haunted frequently, thus changing the taste and composition of the nearby mist, so that the highland spies were marked with a special smell. Although it is difficult for humans to detect this special smell, the sensors made by Nina can detect their movement path very keenly, so the spies' whereabouts are locked at once.

Therefore, the process of the spies going back to report the news naturally also served as a guide for Tianying, so that the "iron ball" could easily lock the location where the army on the high ground was really stationed, so as to launch an offensive.

As for the huge explosion on the cliff just now, it was actually due to the "iron ball". The container is filled with a high concentration of explosives, so its coverage and lethality are also extremely strong. Therefore, after the directional explosion just now, the highlands also suffered huge losses.
