"The methods may be a bit extreme, please forgive me, Commander Chao." Xin'er said a little embarrassedly.

Chao Qingsheng waved his hand and said, "Haha, it's okay, it's much better than letting those beasts destroy everything."

"Thank you, the three heroes, for solving a big problem for us."

As he said that, Chao Qingsheng bent down slightly at the three of them.

"There is no need to be so polite to command the Chau." Xin'er hurriedly helped Chao Qingsheng up and said, "Chiu Commander, I have a question."

"Miss Xin'er, but it's okay." Chao Qingsheng said.

Looking at the ground ants under the deep pit, Xin'er said, "If I remember correctly, adult ground ants are only the size of a palm at most. Why do the ground ants here grow so huge that they completely exceed the size of normal ground ants."

Hearing this, Chao Qingsheng sighed and his face was filled with helplessness: "Oh, the three of you don't know that the Xiyang Grassland is the largest grassland in the Ming Empire. Although the terrain is flat and the soil is fertile, it is not as safe as it looks."

"The grassland is connected to the Huoxi Mountains in the west, the south is next to the Giant Spirit Field, and the north is a wasteland. In other words, the environment on three sides of the grassland is very harsh, which leads to the frequent invasion of spiritual beasts in the grassland."

"The duty of our soldiers in the grassland is to remove the spirit beasts that invade the grassland and prevent foreign spirit beasts from destroying the spirit beasts in the grassland."

"Is the spirit beast in the grassland so important?" Xin'er said in confusion.

Chao Qingsheng nodded, "The three should have seen that most of the grasslands are low-level spirit beasts. The reason they are kept here is because they are important sources of meat and strategic sources of material."

"The spirit beasts raised here are transported to various cities every day to ensure sufficient supplies in each city. At the same time, due to the excellent grass quality and fertile soil, the spirit beasts here will not only raise them as food for the whole country, but also send some excellent species of spirit beasts to the imperial capital for use as war horses."

"So that's it." The three of them nodded thoughtfully.

"The strategic role of this grassland is very huge. However, due to the dangerous terrain and vast plains, the empire was unable to build a wall like the Kaming Wall. It could only station a large number of soldiers in the grassland to ensure the safety of the grassland."

"In other words, did those large group of land ants enter the grassland from other places?" Xin'er asked.

Chao Qingsheng nodded, "If I were good, there should be a queen of ant sneaking into this place from the Giant Spirit Field. Since there are no natural enemies here, it can hide underground and reproduce freely, so the ground ants here are so huge."

"When we discovered it, the grassland was covered with giant tunnels dug by ground ants, and the grassland was completely an underground kingdom of ground ants." Chao Qingsheng said.

"Since that's the case, it's better to kill all the underground ants. Although these ants are huge, their strength is not as strong as imagined. With the strength of the imperial army, it should be quite simple to make them clear." Si Yu said.

Chao Qingsheng sighed and said, "It would be great if this is true. Although these land ants are not strong, they are extremely united and reproduce very quickly. Adult ants can lay an average of 1,000 ant eggs a day. No matter how fast we kill, they are not as fast as the queen of the ants."

"Since that's the case, just kill the queen of the ant." Siyu said.

"The problem is here. These land ants are very loyal to the queen. They will do their best to protect the land ants. Moreover, the queen will usually be hidden in a safe place. We have not found the queen's location until now." Chao Qingsheng said with a disappointed expression.

At this moment, Xin'er suddenly remembered the voice of Xiao Jiji in her mind.

"Master Master! Let's go and destroy the queen of the ant!"

Xin'er was startled and said in her heart: "Xiao Jiji! I can hear your voice again!"

"The Giant Spirit Field is not far from this, of course I can communicate with you very easily. Okay, master, don't talk about it, let's quickly kill the queen of the ant. That guy is of great use to me!"

"But you also heard that the nest commander did not find the location of the queen." Xin'er said.

"It's okay! I can find it. Later, you just need to find what I said."

“How to do it?”

"After a while, you're like this..."

Xin'er gradually came to her senses and said to Chao Qingsheng: "Chao Commander, I have a way to find the queen of the ant and kill it!"

"Really! What's the solution?" Chao Qingsheng said excitedly.

"Captain, is there an underground passage nearby?" Xin'er asked.

"Yes! There is a passage not far below the hill!" Chao Qingsheng said.

"Then please help the commander of the nest, and I will go down and clear the queen of the ant, so that the grassland will be much safer." Xin'er said.

"But, will this delay the trip of the three of you?" Chao Qingsheng hesitated.

"It's okay, it won't take long, and I believe the two sisters won't mind either." Xin'er said.

Leng Yue and Siyu nodded with a smile. As Xin'er's good sisters, they will support them unconditionally no matter what decision Xiner makes.

"Since that's the case, there will be three heroes."

Chao Qingsheng said, then took Xin'er and others to an open space, lifted the grass, and saw a huge hole extending all the way to the ground.

A ray of sunlight shone at the entrance of the cave, illuminating the dark entrance, allowing Xin'er to barely see the structure below.

Under the entrance of the cave is a yellow channel that extends to the left and right. The surrounding soil looks very strong, as if it is deliberately reinforced. Every distance in the channel, a column stands in the middle to support the lower channel so that the grassland above will not collapse.

"Ground ants usually forage at night or early morning. Most of them hide underground at this time and rarely come out." Chao Qingsheng explained.

"Commander of the Nest, there should be more than one such hole, right?" Xin'er asked.

Chao Qingsheng nodded, "Well, we found a total of eighty-one such holes in the pasture."

"You should quickly notify the commanders of other fortresses and ask them to lead the soldiers to stand by the entrance of the cave. There are very likely a large number of ground ants running out of the entrance of the cave later."

Chao Qingsheng nodded, "I'll send someone to inform the commanders of other fortresses."

Chao Qingsheng said this and left and sent a few soldiers with good feet behind him to notify other fortresses to ask them to stand by at the entrance of the cave.

After looking at the passage that was beyond the end, Xin'er said to Chao Qingsheng: "Okay, let's go and come. Chao commander, you can wait outside for a while."

Chao Qingsheng looked at the three of them and said with some concern: "Miss Xin'er, do we really need to go down and help?"

Xin'er shook her head and said, "No need, too many people will start to alert the snakes when they go down. The three of us are enough. Those three storm horses, please ask the commander of the nest to take care of us."

As he said that, Xin'er and the other two jumped out of the hole.

"despair."

As soon as the three of them landed, they couldn't help but exclaim. The lower passage was much more ticking than they thought. The diameter of the passage was at least five meters and the height was more than three meters, which was enough for five giant ground ants to pass side by side, just a veritable underground world!

Looking at the east and west like a road, Siyu asked, "Xin'er, where are we going?"

Xin'er bent down and pinched the soil under her feet. The soil in the east was obviously tighter than the west.

"Let's go east!"

As he said that, the three of them walked quickly towards the east.

Not long after they walked, the three of them came to a huge open area, with dozens of underground tunnels connected around the area, like a huge palm-leaf fan, the three of them were standing at the handle of the fan, like three ants standing in the palm-leaf fan.

Looking at the tunnels around him that were exactly the same, Siyu asked again: "Xin'er, where will we go this time?"

Xin'er smiled mysteriously, "Hehe, this time, we don't rush to leave."

Having said that Xin'er came to the center of the empty area and poured out a bunch of spiritual cores from the storage ring - these spiritual cores are all low-level spiritual cores, which are useless for Xin'er now, and it is perfect to use them as bait.

Xin'er fell for a quarter of an hour until the spirit core piled up as high as a hill before gradually stopping.

Looking at the mountains of spiritual cores in front of him, Siyu sighed: "I didn't expect that Xin'er, you are the richest woman who hides the deepest. If these spiritual cores are sold, they will be more than Guo Zi's family's annual income."

"How is this possible? These are low-priced spiritual cores, which are not worth much." Xin'er said.

"Xin...Xiner, what are you planning to use these spiritual cores?" Leng Yue asked.

Xin'er grinned and said, "Hehe, of course it's the land ants."

"Flying ant?"

Xin'er smiled mysteriously, looked at Leng Yue, and said affectionately: "Sister Leng Yue, can you help me crack all these spiritual cores?"

Looking at Xin'er's big eyes that were fascinating and lifeless, Leng Yue sprayed two balls of hot air from her nose, patted her chest and said, "Of course! You're ready!"

Xin'er hugged Leng Yue's waist and said excitedly, "That's great, thank you Sister Leng Yue! Remember, you just need to crack the spirit core, and you don't need to break it."

Nodding heavily, Leng Yue looked at the spirit core in front of her, took a deep breath, and spit out a large fire from her mouth, instantly covering the entire pile of spirit cores.

Fourth-level fire magic - fire surging!

Under the control of the cold moon, the temperature of the flame is not too high, but always remains at a suitable temperature. These spiritual cores become more rosy and more fragile after the continuous scorching of the fire.

"Click!"

Only a crisp sound was heard from the flames. The spirit core of a second-level golden steel badger was finally unable to withstand such scorching, and a crack appeared.

"Click...Click..."

More and more spiritual cores were cracked, but none of them were broken. The spiritual energy seeped out of the cracks and drifted towards the tunnel entrances along the wind.

"Enough of Sister Leng Yue! Enough of it!" Xin'er grabbed Leng Yue and said.

Leng Yue then withdrew the flames and looked at Xin'er and said, "Xin...Xiner, how am I acting?"

"I performed so well! I love you so much!" Xin'er said that and pecked Leng Yue's face.
Chapter completed!
