Rong Zhen took Gu Yunru and fled from the back road. They finally reached a relatively safe place. Rong Zhen couldn't bear to watch the group of people fighting in a group while he slipped away at ease. He pressed her shoulder and said solemnly: "Go back and wait for my news first, and tell the admiral about this matter."

"What about you?"

Seeing Rong Zhen's expression, so heavy, I knew that he must have put his own life and death aside.

"Don't worry about it. Reporting the news is the most important thing." The officials stationed on the city wall were waiting for news from Rong Zhen. Gu Yunru had to rush back as soon as possible to tell them about the battle situation here.

"Well, be careful, I'll wait for you to come back."

"Yes." Rong Zhen's eyes were full of determination and stubbornness. He watched her leave before returning to the back of the mountain. Suddenly, the sky darkened and Gu Yunru lost her way. The officials near the city wall had received intelligence in advance, so they urgently closed the city gates, but Gu Yunru was still outside the city gates.

The city gate was closed and it was impossible to open it for her alone, so she had to hide in the caves and holes in the nearby mountains for the night and try to find a way to return to the city gate early the next morning.

But I didn't expect to meet Cheng Shaoyuan here by coincidence.

"Cheng Shaoyuan... why are you here?" Gu Yunru shouted in bewilderment. Cheng Shaoyuan's expression was the same as hers. He stared at her suspiciously with his not-so-big eyes and asked, "How do you know my full name?"

"...Hey, everyone knows that Lord Cheng is famous, but the foreign country is about to go to war with Da Qi, so why are you hiding in this small cave?" Gu Yunru asked curiously, puzzled. She saw a few scratches on his forehead, and she didn't know whether he had just fought a life-and-death battle with something.

"To be honest, I buried Heng Niang's body myself, but I didn't expect to come back too late. Seeing that the city gates were already closed, it was unrealistic to ask the admiral to open the gates. I planned to hide here for a night and enter the city gates early the next morning after the melee."

Seeing his dusty face, it seems that what he said is true. Cheng Shaoyuan's feelings for Heng Niang are really admirable. Thinking of this, Gu Yunru leaned in again. This cave was originally very narrow, and it was already good enough for two people to get in. If there was a war and artillery fire here, it would definitely collapse into a pile of earth. Thinking of the thousands of troops passing over it, it is estimated that the two of them would be buried in the loess.

"But sir, have you ever thought about whether Heng Niang was killed by those evil monsters from a foreign country?" Gu Yunru's pair of dark eyes were still emitting brilliance in the night. Cheng Shaoyuan's dark eyes were full of calmness. At this time, he had heard that the evil monsters from a foreign country had led thousands of troops to attack the city gate and were setting up camp nearby.

"Oh no, it looks like they have already broken in." Gu Yunru frowned. At this moment, he saw that all the insects, big and small, in the cave were crawling out. It seemed that these clever little guys also knew that an act of devastation to all living things was about to break out.

"Miss Ashin, look at these insects, they are lined up in such an orderly manner." Cheng Shaoyuan had never seen such a strange scene before. It was as if someone was calling them from a not far away.

"Yeah, I'm really curious." Gu Yunru grabbed a stone behind him and smashed it at one of the insects. The insect was instantly smashed to pieces, but it did not affect the other insects from moving forward.

They seemed to be organized and were heading to one place. Gu Yunru curiously followed their team.

But the scene before her astonished her. She didn't know what kind of evil magic those foreign monsters used, but these insects climbed up the walls of the capital city in neat rows and bit all the ropes and weapons into pieces.

"It's bad, it's bad, sir!" Several elite soldiers standing on the city gate wall were unable to resist. The prepared archers and some weapons such as firearms were all eaten clean by the insects.

"What's the rush?" The newly appointed admiral was Lord Shen's former subordinate. He was decisive and efficient in his actions and was a good official serving the country and the people. When he heard his subordinate describe such a ridiculous scene, he would never believe that such a strange thing could happen.

Without saying a word, they went to the city gate and took a look. They were so scared that they almost fainted. They didn't know why these insects climbed up the wall and started biting their weapons.

Gu Yunru saw everything clearly from under the city wall. Although the foreign monsters had not taken this opportunity to attack the city, they must be planning something bigger.

"What the hell happened outside?" Cheng Shaoyuan also followed out out of curiosity and was nearly discovered by the patrolling soldiers of the foreign monster group. He was pulled into the cave by Gu Yunru, who raised his index finger and hushed him with a serious expression. He told him word for word what he had just seen.

"Really? Are you kidding me?" Cheng Shaoyuan had never seen such a strange scene before. Could it be that the insects were also controlled? Although he had heard that foreign countries were good at using Gu to control other people's minds, those soldiers were like puppets, and they didn't care about their lives when fighting.

"I'm definitely not lying to you. Now we should think about how to stop those bugs." Gu Yunru racked her brains, but still had no clue. She didn't know where the key to the problem lay. Those bugs definitely couldn't have independent consciousness and would definitely attack indiscriminately.

"What have you thought of?" Cheng Shaoyuan asked curiously when he saw her thoughtful look. He crawled into the cave and planned to start from the insects' nests.

"I know what the problem is!" Gu Yunru saw some meat scraps scattered on the ground. These meat scraps were most likely artificially made. As for what kind of meat this was, Gu Yunru thought of the green blood that flowed out of the soldiers after being controlled by the Gu.

It is very likely the flesh of those soldiers... Miao Xiang actually used such a vicious scheme to control the minds of those insects, especially the five poisonous beasts like the centipede, which are extremely poisonous.

"What's the problem? What have you discovered?" Cheng Shaoyuan was very curious. As he was asking, an insect crawled onto his shoulder. Gu Yunru saw this and immediately winked at him, wanting him to shut up. Insects can reflect who is beneficial to a person and who is harmful to him based on his breathing and sound waves.

Gu Yunru took a small wooden stick and gently touched the insect. The insect suddenly became very aggressive. It bit the stick and was dragged to the ground by Gu Yunru. She stepped on it hard and found that there was green blood. It seemed that her guess was not wrong.
