Instead, she was dragged out for a distance. Before leaving the door, she held on to the edge of the door with her other hand, but her eyes were looking outside.

The tree that looked normal yesterday has now turned into a mutant tree that is twice as big as yesterday, and all of its branches and vines cover this floor.

Seeing Xu Bai's predicament, Ji Heng rushed to Xu Bai's side without caring whether the vines would hurt him, pulled Xu Bai inside, and cut off the vines tied around another person's waist.

"careful."

Only then did they realize that the person who was grabbed and dragged out was Ye Yu. Ye Yu was still in shock after being rescued. While cutting off the vines next to him, he thanked Xu Bai and Ji Heng.

As Xu Bai and Ji Heng walked out of the house, they immediately attracted the attention of the mutant tree.

The vines wrapped around the roof immediately changed direction, trying to catch Xu Bai and Ji Heng and tie them up.

Xu Bai and Ji Heng took advantage of the situation and did not resist much, allowing the mutant tree to tie them up.

After being tied up, the vines will continue to tighten, as if absorbing the spiritual energy from their bodies, and moving them into the air or even close to the mutant tree.

There is a hole in the middle of the mutant tree.

When they approached the cave entrance, Xu Bai and Ji Heng simultaneously used their psychic powers to explode the vines that bound them. They carried daggers and other weapons with them at all times, and stabbed them fiercely into the cave entrance of the mutant tree, cutting back and forth continuously.

The entrance of the cave is equivalent to the mouth of the mutant tree.

The surrounding area was very sensitive and delicate, and Xu Bai and Ji Heng easily cut off a lot of it.

“..No…don’t…don’t hurt…hurt me…”

The weak voice repeated in her ears.

Xu Bai glanced in the direction of Ji Heng, and it was obvious that Ji Heng also knew that very faint voice.

It took Xu Bai a lot of time to successfully connect his mental power with the mutant tree.

The faint sound came from the mutant tree.

She begged for mercy, but secretly wanted to absorb her spiritual power. Xu Bai felt a force attacking her spiritual sea of ​​consciousness, and realized that it was the mutant tree causing trouble. Without saying a word, she cut off the connection with the mutant tree and turned to Ji Heng and said, "Destroy it."

Xu Bai and Ji Heng went straight to the heart of the tree and dug out its crystal core.

The mutant tree without the crystal core returned to its normal size and became a branch. There were many holes on the trunk, all of which were dug by Xu Bai and Ji Heng.

The people in the house saw the vines shrink back in an instant. When they came out, they saw Xu Bai and Ji Heng digging out the crystal core of the mutant tree.

The crystal core of the mutant tree is very large.

Xu Bai couldn't hold it in one hand, and it was translucent in color, with a dazzling green light, like a beautiful emerald.

This is a sixth-order wood crystal core.

Xu Bai was very surprised.

"Xu Bai, A Heng, why do I feel like this northwest part is even more dangerous than ours? How about I stay here for a while and go back after the railway is built?"

Shi Qinghe ran up to them, glanced at the crystal core in Xu Bai's hand, and looked at them with an anxious expression.

"I'm worried that you might run into a situation like last time. I'm here to look after you. With one more person, we can finish this faster."

"What about Dawn City?"

The northwest is more dangerous. Compared to zombies, these natural mutations are more serious.

"My parents and Jiao Nanmu are still here in Shuguang City. There will be no problem."

With Shi Qinghe's soft and hard tactics, he stayed.

We continued to build the railway together.

Despite the large number of people, the construction of the northwest section took a full three months.

During these three months, they suffered from the disturbance of countless animals and some natural disasters, but fortunately they never encountered a situation like the oasis again.

After the northwest part was completed, Xu Bai and others built towards Shangjing City.

Shangjing City also sent people to build the railway, but they encountered an even worse situation. In addition to mutated plants and animals, a large number of zombies were chasing them.

After learning that Rongcheng was building a zombie brigade, Shangjing City wanted to borrow "people" from Rongcheng, but was worried that it would not be suitable to come to Shangjing City.

So the plan kept being paused.

Xu Bai and others happened to run into people on their way to Shangjing City and from intermediate cities in the northwest and Shangjing City to build the railway.

From a distance, I could hear this group of people arguing, hoping that Shangjing City could send a zombie construction team to help.

"It seems Miao Zheng has her own way of taming zombies."

"This has led to a competition for workers."

Shi Qinghe and I were proud of it. "That's right, she is my sister after all."

"However, they are arguing so fiercely, aren't they worried about attracting zombies?"

Shi Qinghe is a jinx to some extent.

Not long after he finished speaking, he saw zombies slowly coming towards him not far away.

“There are zombies!”

Shi Qinghe kindly reminded those who were still arguing.

As soon as they heard the word zombies, they immediately calmed down. When they turned around, they saw Xu Bai and others, and they all rushed to Xu Bai's side.

"Xu Bai, great! I'm the commander-in-chief here. My last name is Liu."

In addition to Commander-in-Chief Liu, Mu Jing is also among those responsible for building the railway here. Someone in her family used to be a railway employee, so she came along.

But the person who was constantly arguing with her was Commander-in-Chief Liu.

Mu Jing and others hoped for support, but there was a team that either thought too highly of the guards or was too confident in themselves. They felt that they could handle it easily and did not need a zombie construction team. This would save them from having to use more force to monitor the zombies to see if they would suddenly return to their old ways.

If they don't provide support, they will be in danger. If they have support from friendly zombies, they will also be worried about danger.

Isn't this just asking for trouble?

Mu Jing was so angry that she started arguing with him.

Mu Jing tried hard to force a smile at them, then turned around and led people forward to clean up the zombies that were coming over.

"Commander Liu, this is the only part we haven't finished building yet, right?"

Xu Bai had no impression of this person. He was not worried about the other zombies running over, as he thought others would take care of them.

"Uh, yes."

Xu Bai didn't waste time talking to others. After he took his men to clear out the zombies, he started to build the railway.

At this point, their first step in infrastructure railway construction was completed.

The Flower Country has built a circle of railways from south to north and from east to west, and the remaining area is the central area.

Shi Miaozheng usually takes the zombie infrastructure engineers under her command to places that have never been to before to build railways together.
