"Yes!" Jiang Yuntian replied, and then handed over the video sent back by the reconnaissance plane to a soldier, who then returned to the main island of the alliance with the video.

Send it to Duan Beiyang, Alliance Design Institute, and let him draw an accurate topographic map with intelligent engineering mapping equipment!

As long as there is a video, the topographic map is quickly drawn and sent to Jiang Yuntian through the wormhole.

Jiang Yuntian flattened the topographic map in front of everyone.

All the aliens present were shocked.

In just a few minutes, they have completely drawn the topographic map of the nearby battlefield!

"How did you do this?" Tian Wu couldn't help asking.

Xiao Yi replied with a smile: "This is technology. You can visit our Alliance Island if you have the chance. Technology can change our lives and the way we fight!"

"Okay, after the war has eased here, I will definitely visit your island! I hope Island Master Xiao will not drive us out!" Tian Wu said with a smile.

"How could it be? As long as it's a friend, we welcome you with both hands!" Xiao Yi replied.

Jiang Yuntian looked at the topographic map in front of him and said, "The front line in front of Ghost Gate Pass is too long. We now have two options. One is to quickly capture Ghost Gate Pass, and then cut off the pass, so that the undead cannot continue to support it. The undead on our side can be cleaned up slowly. At the beginning of this plan, we may be attacked by the undead on both sides!"

"This is still a bit rash, I suggest to play steadily, and rush into the situation of two sides, which is very dangerous!" Tian Wu said in a deep voice.

The elf beside him also nodded in agreement.

"The second plan, we will fight steadily, everyone will start to eliminate the undead from both sides, and advance step by step to the gate of hell, but this plan will take a long time, and we may be in a hard fight!" Jiang Yuntian continued.

Xiao Yi shook his head and said, "It's too slow to play steadily like this, and when you are eliminating these undead, there are still undead coming in at the gate of hell, we have to cut off their source first. Clean up the undead on our side!"

Hearing Xiao Yi's opinion, Tian Wu and the others frowned.

Xiao Yi continued: "In this way, you dragon people and elves are on both sides, attracting and clearing the undead on both sides, how about we clean up the undead in the middle and capture the ghost gate?"

Tian Wu and the elf looked at each other and said, "Okay, but if you can't capture the gate of hell, don't be brave!"

"Don't worry, we won't joke about the lives of our soldiers!" Xiao Yi replied.

"Okay, then launch an attack immediately after ten minutes!" Tian Wu said, then walked back and summoned his clan!

The elf also rushed back, ready to fight!

Ten minutes passed in a blink of an eye, Jiang Yuntian ordered: "The artillery covers the gate of hell, and the machine gun platoon moves forward immediately!"

Boom boom boom!

The artillery positions of the Yi Ran Pin Alliance immediately began to roar.

Countless cannonballs flew towards the gate of the ghost gate and immediately emptied the undead near the gate of the ghost gate, but a pile of skeletons poured in immediately from the gate of the ghost gate.

And the shells on Xiao Yi's side flew again and emptied them again.

Skeletons are constantly pouring out of the gate of the ghost gate, and cannonballs are constantly falling in the air!

Most of the skeletons in Ghost Gate simply cannot safely pass through Ghost Gate.

Jiang Yuntian started to move forward steadily with the machine gun platoon!

Da da da!

They clear the undead much faster than the dragons and elves!

The black robe among the undead was standing near the gate of the ghost gate, and when he saw Xiao Yi's firepower being so fierce, he was horrified!

"Are they going to take over the gate of hell?" Hei Pao frowned.

But Guimenguan is an important place that it guards. If it falls, the advantage of the undead will not be there!

So it must stay here!

Thinking of this, Hei Pao immediately ordered: "Be sure to block those advancing in the middle, our team will speed up the attack!"

"Yes!"

Following the black robe's order, the undead on both sides suddenly rushed to the middle!

Jiang Yuntian, who had already advanced 200 meters, saw the undead on both sides suddenly rushing in, and he immediately ordered: "Retreat!"

The machine gun platoon of the Yiranpin Alliance retreated again.

The dragons and elves on both sides were shocked when they saw the movements of the undead, and shouted loudly, "Come on, you must hold them back!"

The dragon people and the elves immediately increased their offensive, but the undead still ignored them and rushed straight to the middle.

Xiao Yi watched the changes in the battlefield situation, squinted at the black robe in the distance, and said to the soldier beside him, "Give me a sniper rifle!"

The soldier on the side immediately handed over a Barrett!

Xiao Yi estimated the distance, then raised Barrett and shot at the black robe!

Bang!

The sound of Barrett's sniper rifle was completely drowned out by the sound of artillery fire!

And the black robe on the other side of the gate of the ghost gate suddenly burst open, and some pieces of meat actually burst out!

Then the black robe slowly fell down.

Xiao Yi was a little surprised, he always thought that the commander of these skeletons should also be skeletons, but now it seems that they are not!

The sniper on the side looked at Xiao Yi in shock.

The distance between Xiao Yi and the black robe should be more than two kilometers. This distance is already the limit of the range of the Barrett sniper rifle. Xiao Yi actually killed it with one shot!

"I didn't expect the island owner's marksmanship to be so powerful!"

"Yeah, this distance is already the limit distance that the instructor said!"

"No wonder the instructor keeps saying that the island owner is more powerful than him!"

Xiao Yi listened to their whispers and ordered helplessly: "Follow the machine gun platoon, and if you encounter that kind of persecutor wearing a black robe, shoot me directly!"

"Yes!" the crowd responded.

After the black robe was killed by Xiao Yi with one shot, the entire formation of the undead stopped for a while, and then began to chaotic.

When Jiang Yuntian saw that the black robe was killed, he turned around and gave Xiao Yi a thumbs up, and then continued to advance with the machine gun platoon.

The artillery in the rear was still roaring, and most of the skeletons in the gate of the ghost gate died in the gate of the ghost gate.

Without the black robe commander, Jiang Yuntian and the others quickly advanced to the vicinity of the Hell Gate.

"Build fortifications on the spot!" Jiang Yuntian ordered.

"Yes!"

At this time, Jiang Yuntian and the others focused their defense on the undead on both sides.

There are artillery in front to help them clean up, so there is no need to worry too much.

Jiang Yuntian and the others held on for half an hour at the gate of the gate of the ghost gate, and the dragon people and the elves finally cleaned up here.

After they met, the skeletons in the gate of the ghost gate suddenly stopped rushing out, and then withdrew back, as if they felt that they could no longer hold the gate of ghost gate, and gave up!

"Is there still a commander?" Xiao Yi murmured suspiciously while watching this scene.
