He had known for a long time that Xu Ying could travel through time, but this was the first time he heard of such a thing.

Wei Shishi, who had been expressionless, looked at Xu Ying with deep vigilance and a hint of fear in her eyes.

If this kind of thing could be realized, it would be like killing people invisibly!

"I definitely wouldn't do such a thing, and aren't we talking about the beast tide? Wei Shishi, please continue. I don't know much about this either." Xu Ying said, leaning back in her chair.

Although she wasn't entirely satisfied with Xu Ying's slouched posture, Wei Shishi didn't waste any more words. Instead, she continued, "A hundred years ago, the human base was devastated by the onslaught of giant beasts, and most of the people on the periphery fled inward."

"The tide of giant beasts is almost endless!"

"At that time, almost all the soldiers were on the front lines. Hundreds of years of accumulated strength were completely depleted in a single year. Military resources were also depleted to an incredible degree, more than the previous nine hundred years combined."

"As the Wei family, which controls the military, we suffered the greatest losses in that disaster and lost control of this underground human base. The three families began to compete with each other."

"That's exactly what happened." Xu Ying nodded. "Our original plan was to support one family to become stronger than the other two. Although the three families were competing against each other on the surface, the Wei family secretly had the ability to reorganize the three families. With just a little help, we could have the ability to centralize power. However... the sudden disaster a hundred years ago turned the apparent situation into a real situation."

"That's how it is." Old man Wei Bai sighed again, "Fifty years ago, when Xu Ying and Xu Xin came, they wanted to help us become stronger again and take back control."

"But unfortunately, our strategic resources had been exhausted by then. We had technology but no resources, and there were also wild beasts invading from the outside. Under internal and external troubles, the Wei family was really struggling. So at that time... sigh..."

Wei Shishi nodded and continued, "Over the past fifty years, the beast tides have continued. And it's not just the external beast tides. They've also taken over almost all the sparsely populated areas within the base. They've become true wild beasts."

The size of the human base now is almost equivalent to the area of ​​a large country on Earth a thousand years ago. In such a large area, it is understandable that there are wild beasts roaming inside.

With such a long border and so many beasts, there's no way to defend...

"Fortunately, in the past twenty years or so, these beasts have settled down. Especially the beasts within the territory, they almost never attack human bases anymore, but have integrated into the ecology of this area."

"But even so, in order to prevent disasters before they occur, necessary resource consumption is essential. Over the past fifty years, our resources have continued to slowly decrease."

"So..." Wei Shishi looked at Li Wenxi, "If you really have that ability, please save us."

"If this continues, this human base will lose its ability to protect itself."

Li Wenxi had a basic understanding of the current situation of the human base. She nodded quickly, "Of course, I will help you. This is why I came here. Besides, during my time here, I've already discovered a mining site."

"Already discovered?" Wei Bai and Wei Shishi were both shocked.

Xu Ying chuckled: "Sister-in-law's ability is definitely a real lifesaver for you right now."

The most important purpose of her bringing Li Wenxi here was not to save this underground world whose resources would be exhausted in a few decades.

After all, the most important resource, crystal stones, has almost been exhausted.

Although crystal stones contain enormous energy, humans underground are unable to mine and utilize them. They can only be used to release light and passively release energy.

Similar to the effect of the sun.

However, the crystal stone that maintains the basic energy source of the underground world, which is essential for the maintenance and expansion of human bases, has almost been exhausted within a thousand years.

Survival in the underground world is not a long-term solution after all.

Xu Ying brought Li Wenxi underground, more because she wanted Li Wenxi to provide resources to manufacture a large number of weapons here, and turn this underground human base into a crazy operating underground arsenal.

It is not only to defend against the beasts underground, but also to prepare for future battles on the ground.

This was their original purpose, to make this underground force one of the backbone forces in resisting alien invaders in the future.

This beast invasion that lasted for a hundred years consumed too much power of the underground world. There was no choice but to replenish it now.

Fortunately, the current progress on the ground has not yet reached the point where a large-scale weaponry and army is needed.

However, we must hurry up!

Wei Bai showed a look of joy, stood up, and without questioning, asked directly: "Where is the location of the resources?"

"Well, it's near where I live, but it's..." Li Wenxi pointed above his head.

"Up there..."

"Well, do you have the ability to mine upwards?"

Wei Shishi pondered for a moment. "This involves some problems. Technically, there's no problem, but regarding safety risks... If there are residential areas below, people might need to be relocated first. If it's a densely populated area, it might be more troublesome..."

"That's the outskirts of the city, and not many people live there," Li Wenxi recalled.
