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

Send it to Duan Beiyang of alliance Design Institute and ask him to draw an accurate topographic map with intelligent engineering mapping equipment!

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

Jiang Yuntian tiled 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 that?" Tianwu couldn't help asking.

Xiao Yi replied with a smile: "this is technology. If you have the opportunity, you can go to our alliance island. Technology can change our lives and our way of fighting!"

"Well, after the war here eases, I will visit your island! At that time, I hope Island leader Xiao won't drive us out!" Tianwu said with a smile.

"How? As long as we are friends, we welcome with both hands!" Xiao Yi replied.

Jiang Yuntian looked at the topographic map in front of him and began to say: "The front line in front of the ghost gate is too long. We now have two plans. One is to quickly seize the ghost gate, and then cut off the ghost gate, so that the undead can't continue to support. The undead on our side can clean up slowly. At the beginning of this plan, we may be attacked by the undead on both sides!"

"It's still a little rash. I suggest we should be steady and rashly fall into the situation of double attack. It's very dangerous!" Tianwu said in a deep voice.

The elf on one side also agreed and nodded.

"In the second plan, we will fight steadily. We will eliminate the undead from both sides and advance to the gate of hell step by step, but this plan will take a long time, and we may fall into a hard battle!" Jiang Yuntian continued.

Xiao Yi shook his head and said, "it's too slow to fight so steadily, and when you destroy these undead people, there will still be undead people coming in at the gate of hell. We have to cut off their source first to clean up the undead people on our side!"

Hearing Xiao Yi's opinion, tianwu and them frowned.

Xiao Yi continued: "in this way, you dragon people and elves are on both sides to attract and clean up the undead on both sides. How about we clean up the undead in the middle and capture the gate of hell?"

Tianwu looked at the spirit and said, "OK, 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.

"OK, attack immediately in ten minutes!" Tianwu said, and then went back and called his people!

The spirit also rushed back and was ready to fight!

Ten minutes passed in a flash. Jiang Yun ordered: "guns cover the ghost gate, and machine guns move forward in a row!"

Boom, boom!

The artillery positions of yiranpin alliance immediately began to roar.

Countless shells flew to the ghost gate and emptied the undead near the ghost gate immediately, but a pile of skeletons poured in at once.

The shells from Xiao Yi's side flew again and emptied them again.

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

Most of the skeletons in the ghost gate cannot pass through the ghost gate safely at all.

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

Dada, dada!

They clean up the undead much faster than the dragons and elves!

The black robe of the undead stood near the gate of death. He was shocked to see that Xiao Yi's firepower was so fierce!

"Are they going to win the gate of hell?" The black robe frowned and whispered.

But the ghost gate is an important place to guard. If it is lost, the advantage of the undead will not be there!

So it must stay here!

Thinking of this, the black robe immediately ordered: "we must block those who advance in the middle, and our team will speed up the impact speed!"

"Yes!"

With the black robe order issued, the undead on both sides suddenly rushed to the middle!

Jiang Yuntian, who had pushed 200 meters forward, saw the undead on both sides suddenly pouring in. He immediately ordered: "retreat!"

The machine gun platoon of yiranpin alliance retreated again.

When the dragon people and elves on both sides saw the action of the undead, they were surprised and shouted, "rush, we must drag them!"

The dragons and elves immediately stepped up their offensive, but the undead still ignored them and rushed straight to the middle.

Xiao Yi looked at the changes of the battlefield situation, squinted at the black robe in the distance, and said to the soldiers on one side, "give me a sniper gun!"

The soldiers on one side immediately handed over a Barrett!

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

Boom!

The sound of Barrett's sniper gun was completely covered up by the sound of gunfire!

The black robe on the other side of the gate of hell suddenly burst his head, and some broken meat burst out of it!

Then the black robe fell slowly.

Xiao Yi was a little surprised. He always thought that the person who commanded these skeletons should also be skeletons. Now it seems not!

The sniper on one 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 distance of Barrett sniper gun's range. Xiao Yi killed him with one shot!

"I didn't expect the island Master's shooting skills to be so powerful!"

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

"No wonder the instructor always said that the island Master was better than him!"

Xiao Yi listened to them whispering and reluctantly ordered: "you follow the machine gun platoon. If you encounter a forced criminal in a black robe, you'll snipe directly!"

"Yes!" The crowd answered.

After the black robe was shot by Xiao Yi, there was a slight pause in the movement of the whole formation of the undead, and then it began to mess up.

Seeing that the black robe was killed, Jiang Yuntian turned back and gave Xiao Yi a thumbs up, and then continued to move forward with the machine gun platoon.

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

Without the command of black robe, Jiang Yuntian and others soon pushed to the vicinity of Guimen pass.

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

"Yes!"

At this time, the focus of Jiang Yuntian's defense was the undead on both sides.

There are guns in front to help them clean up. There's no need to worry too much.

Jiang Yuntian and his family stayed at the gate of the gate of hell for half an hour, and the dragon people and the elves finally cleaned up here.

After they met, the skeletons in the ghost gate suddenly stopped rushing out, and then withdrew. It seemed that they could not win the ghost gate and gave up!

"Is there a conductor?" Xiao Yi looked at this scene and muttered suspiciously.
