Just when Li Yao took people to count the losses in the camp, Ning Feng also immediately took Hua Mulan back to the underground Great Wall to check the situation, he was afraid that the earthquake just now would cause a collapse and blockage to the underground Great Wall.

Sure enough, Ning Feng only took a brief look inside the underground Great Wall, and found that there were many cracks in the underground Great Wall, and there were even serious collapses in some sections.

Immediately, Ning Feng's heart also became more uneasy, he was afraid that the underground Great Wall would be completely cut off, so that not only would the large army of Sanjiang Town not be able to go north to Shaanxi, but even he himself would not be able to go back.

Thinking of Gongsun Li and the others who were still left in Sanjiang Town, Ning Feng's heart also became more impatient and chaotic, and he immediately probed deeper into the underground Great Wall.

"Little Brother Ning, be careful above!"

Just as Ning Feng continued to investigate, Hua Mulan, who was accompanying her, suddenly yelled, and hugged Ning Feng and jumped back more than ten meters.

Bang~

At the moment when Ning Feng was pulled apart, several huge rocks also fell from his head, smashing right on the position where Ning Feng was standing just now.

"It's dangerous!" Looking at the dozens of tons of boulders in front of him, Ning Feng was also terrified, and couldn't help but exclaim in amazement.

"Ning Feng, stay calm! Calm your mind! Mulan said to Ning Feng.

According to Mulan's understanding of Ning Feng, with Ning Feng's keen five senses, it is not difficult to predict and perceive the fall of the boulder.

And the reason why Ning Feng didn't notice the abnormality of the boulder was entirely because Ning Feng was restless.

Under Mulan's reminder, Ning Feng also hurriedly controlled his breathing, trying his best to keep himself calm.

After a long time, Ning Feng's inner impatience and chaos were gradually controlled.

"The situation of the collapse is too serious, the underground Great Wall is completely blocked, and if you want to restore the smooth flow of the underground Great Wall, you must have a professional engineering team to excavate it!" Ning Feng looked at the boulders and rocks in the passage, and said with a very solemn face.

It's just that Ning Feng knows very well in his heart that with the current situation, it is almost impossible to find a professional engineering team.

Moreover, even if a professional engineering team is found, it will take at least several months to re-penetrate the clogged underground Great Wall.

Ning Feng was sure that the large army located in Sanjiang Town could not have waited so long.

"Alas~ go back to the camp first, maybe Li Yao and they have a way."

At this time, it was useless to continue to stay in the underground Great Wall, and there was even the danger of being buried by a landslide, so Ning Feng immediately decided to go back to the camp first to find a way.

……

"Daddy, what's wrong with you?" Seeing Ning Feng walking out of the underground Great Wall with a disgraced face, Cai Wenji, who was waiting in the camp, was also stunned, and asked Ning Feng with great concern.

Ning Feng gently rubbed Cai Wenji's little face with his dusty palm, which instantly made Cai Wenji a little flower cat, and said with a smile: "Daddy is fine, don't worry about Wenji!" ”

Subsequently, Ning Feng went to find Li Yao again, explained the collapse of the underground Great Wall to Li Yao, and hoped that Li Yao could think of a way.

"Ning Feng, there are only a few engineering vehicles in our regiment, just with this little thing, if you want to restore the breakthrough of the underground Great Wall, I don't know if you want to get it until the Year of the Monkey!" Li Yao said regretfully.

In this way, Ning Feng tried to find a way over and over, but found that the collapse of the underground Great Wall was impossible to solve in a short period of time.

In other words, Ning Feng wanted to return along the original path of the underground Great Wall, which was already an impossible thing to do.

And now the only way to return to Shu is to follow the highway or railway, across the entire Qinling Mountains.

It's just that such a method is almost impossible to implement, after all, there were a large number of wild animals in the Qinling Mountains before the end of the world, and now in the case of this apocalyptic catastrophe, the Qinling Mountains have become a habitat for mutated monsters.

Therefore, with the current strength of Ning Feng and the others, it is too dangerous to cross the Qinling Mountains from the ground.

Moreover, even if it crosses the Qinling Mountains from the ground back to Shu, it will probably take a lot of time.

However, even if the road back to Shu was as difficult as ascending to the sky, Ning Feng was not discouraged.

Shu has his relatives, and he Ning Feng must go back!

"Ah Li, Lao Cheng, I'll be back!" Ning Feng said silently in his heart.

Immediately, Ning Feng looked to the northeast again, which was the direction of the imperial capital of China.

"Mom, Dad, I'll be back!" Ning Feng said again in his heart.

……

……

In a national research institute in Lianhu District, Chang'an City, a biochemical expert wearing a white coat and a chemical shield is standing quietly in front of a culture tank tens of meters high.

And in the cultivation tank in front of the biochemical expert, a terrifying biochemical monster is being bred at this moment, but it is a gold-level "Demon Wing Dragon".

"The No. 5 Demon Pterodactyl has completed its cultivation and has successfully mastered the innate biochemical skill 'Light Absorption', which allows the Demon Pterodactyl to absorb the surrounding light to cause a temporary blinding within a radius of 300 meters." The biochemical expert looked at the tablet in his hand and described the situation of the Demon Wing Dragon cultivated in front of him with a smile.

No one knows the name of this mysterious biochemical expert, and the people of Chang'an City call him Dr. Annihilation.

Moreover, only a few people know the approximate origin of Dr. Annihilation.

On the first day of the apocalypse, a high-tech biochemical research institute suddenly appeared in the Lianhu District of Chang'an City.

At first, the biochemical research institute was not a concern, because the entire city of Chang'an was dealing with a zombie crisis.

And in this uncared environment, the Institute of Biochemistry often sends combat robots to capture some zombies and bring them into the Institute.

Soon, some biochemical monsters transformed by zombies continued to come out of the research institute.

Swift Hunter, Self-Detonating Ghost, Invisible Ghost, Hulk, Steel Butcher, ......

These cyborg monsters are more powerful than zombies because they are both a combination of viruses and machines.

And the appearance of a large number of biochemical monsters, the killing and extinction brought about by it, also surpassed the crisis caused by zombies.

It was at this time that the army and the supernatural beings in Chang'an City began to concentrate on dealing with the monsters created by the Biochemical Research Institute.

It's just that when humans began to deal with the Biochemical Research Institute, the strength of the Biochemical Research Institute made human beings helpless.

However, the army and the Aliens in Chang'an City did not give up, and they still did everything they could to curb the expansion of the Biochemical Research Institute.

However, when the three-headed biochemical monsters named "Doomsday Phoenix", "Seraph" and "Evil Emperor Dragon Armor" appeared, the entire army and the Strangers in Chang'an City no longer had the courage to confront the Biochemical Research Institute head-on.

It's just because of these three biochemical monsters that their strength is all platinum-level.
