Doomsday Sacrifice

The aurora is constantly changing in the underground cave, fully blooming its beauty and mystery.

With the help of genetic evolution, Li Xun followed the aurora and found the location of the beast lair on the campus of the Polytechnic University, which was not far from where they were, about 100 meters away.

In perception, the polar beast lair is like a torch in the dark night, extraordinarily dazzling, and the extreme energy in its center is extremely strong.

At the same distance, the extreme energy concentration here is almost twice that of the extreme energy outside the Xiancheng TV Tower, which shows how powerful this lair is.

The race of extreme beasts is too scary. Their ecological system is a virtuous circle, descending, building nests, transforming extreme energy, evolving and multiplying, complete and efficient.

Speaking of which, they are most vulnerable when they just landed, and once they gain a firm foothold, their strength will grow exponentially like a snowball.

Their strongest and weakest link is the original polar beast that exists in the form of a nest, so as long as the time is right, Li Xun will not let go of the opportunity to destroy the nest.

This time he is going to do the same.

"It's about thirteen to four meters above the ground, can you dig a hole to go up?" Li Xun looked at Xu Yuntong.

"Yes, but I can only move the soil. If the ground is cement or concrete, my ability will not work."

"It's okay, just dig up as much as you can."

"Oh."

Li Xun said again: "I have a plan, first dig a hole to the ground, try to get as close as possible to the polar beast lair in the school, there are so many auroras here, don't waste it, Xiao Shen, you and Xu Yuntong take this tomato to the open space Wait there, if I move here, I think the polar beasts will be attracted, so you take this opportunity to rush out and go back to the subway station."

Xu Yuntong was taken aback when he heard that, Li Xun was planning to take the risk alone to lure the beasts away to create opportunities for them, doing so would be like sending him to his death.

She was about to speak when she heard Shen Yiqing say: "This is too risky. Although it kills three birds with one stone, there are too many polar beasts. Once you anger them, how do you get out?"

"It depends on the situation. If it doesn't work, you can still go underground. It's not a big problem to escape." Li Xun had planned for a long time. If he didn't have an authentic way, he would definitely not take this risk.

But now there is a ready-made escape route, and the extreme beast may not have a good way in a short time, so it is naturally worth a try.

The risk is definitely not small, but with the risk comes the benefits. The last time I made a fortune by absorbing extreme energy under the TV Tower in Xiancheng, this time the concentration of aurora is greater and the range is wider. While making a lot of money, you can also give the beast a ruthless, this deal is worth doing.

And the longer the time of entering the end times, the larger the size of the nest, this kind of opportunity will only become less and less, since this time it has been encountered, of course we must seize it.

Thinking of the way out of the tunnel, Shen Yiqing no longer objected.

Xu Yuntong saw that the two had reached an agreement, although he still had a lot of questions in his mind, he did not ask more questions knowingly.

Li Xun sensed the concentration of the aurora again, pointed to a direction and said, "You dig up obliquely in this direction, don't worry about not having enough energy."

"Okay." Xu Yuntong agreed and activated his ability.

She raised her hand and put it on the wall, but she didn't make any special movements. After a while, the seemingly abnormally solid soil fell down like sand. At first glance, it was indeed like magic.

Both Li Xun and Shen Yiqing were curious about the ability to control the soil, and stared at it without blinking. It was amazing at first sight, but the efficiency was obviously too low.

A few minutes later, as a nearly one-meter circular hole in the wall gradually took shape, Xu Yuntong's digging efficiency soared.

The soil turned into obedient plasticine in her hands, and what was even more amazing was that there was nothing else on the ground except the pile of soil dug out at the beginning.

She transferred and fused all the excess soil to the surrounding cave walls, making the cave walls as hard and solid as cement.

After the tunnel was dug at the beginning, the follow-up became easier and easier. Xu Yuntong didn't even need to touch the soil. One hand emitted a glowing blue light, and strands of energy penetrated into the soil like thousands of tentacles, directing them to separate in all directions, like a shield. The mechanism works fine.

As time went by, the tunnel gradually extended forward, and Xu Yuntong stopped when the excavation reached about 30 meters.

I saw that her face was slightly red, and her forehead was covered with fine beads of sweat. It seemed that she had consumed a lot of energy. Obviously, digging a tunnel like this was also a physical effort.

"Have you run out of energy?" Li Xun asked.

Xu Yuntong was a little out of breath: "Well, this ability consumes too much energy."

"It's pretty good to be able to dig about 30 meters at a time." Li Xun praised. Although her ability is not offensive, it should be very useful in base construction.

"How long will it take for the energy to fully recover?" Li Xun asked again.

"It usually takes half a day, or about [-] hours, but in the aurora, the recovery is quick, and it takes five or six hours."

"How about eating this?" Li Xun pointed to the cherry tomatoes.

"Eat one before and you can fully recover, but now you have to eat two."

"You couldn't dig such a long distance once before, right?"

"Yes, I used to be able to dig up to ten meters at a time."

"That is to say, you should have evolved more than once, besides what abilities do you have?"

Xu Yuntong said uncertainly: "I don't know if it's my ability. My injury recovered quickly, and my physical strength is much stronger than before."

"Well, it should be. Accelerated healing of injuries and increased physical strength are all very good auxiliary abilities."

As Li Xun said, he picked a ripe red fruit from the tomato pot and stuffed it into his mouth. As the little tomato went down, a warm current rose from his stomach.

The energy contained in this tomato fruit was unexpectedly much higher, reaching 150 units, almost catching up with a polar beast. No wonder Wu Hui wanted to get it even if he killed his classmates.

It's a pity that although Xu Yuntong ate a lot, most of it was used to replenish the energy in her body, otherwise she should be able to start two evolutions.

"This one has 150 units of energy, which is more than that orange tree. The key is that it grows fast. It is indeed a good thing."

"Leaving Aurora may return to normal growth rate." Shen Yiqing said.

"Well, it's very possible. Give it back to Lao Fan. This is his son's property and cannot be given to others."

Li Xun took out two [-]-unit energy balls and handed them to Xu Yuntong: "Eat this to replenish energy."

Xu Yuntong took it in surprise.

After replenishing her energy, she continued to dig the hole in the direction indicated by Li Xun. After two hours, she dug to a place less than [-] centimeters from the ground.

The newly completed tunnel has a diameter of 80 centimeters and a length of about 30 meters. It is less than [-] meters away from the beast's lair, which is the big tree, near the ground.

During the excavation process, he once encountered a root system of a big tree. Fortunately, there was nothing abnormal. Li Xun hurriedly asked Xu Yuntong to avoid it carefully, and buried it again.

After Shen Yiqing confirmed that there were no polar beasts near the ground using thermal imaging capabilities, Li Xun used a hunting knife to open a small hole the size of a bowl. Fresh air and the light of the aurora poured into the hole, and the first step of the plan was successfully completed.

Next, Shen Yiqing took Little Tomato and returned to the cave in the open space along the tunnel with Xu Yuntong.

She first used the walkie-talkie to contact Lao Fan, and asked him to notify Bai Yuandai that they should retreat to the subway station.

After Li Xun received the news that their retreat was complete, he started the second step of the plan. The next moment, the situation changed.
