Chapter 161 Ground Track Attack and Defense

Between the two-star welfare treatment offered by Shuangxuan Academy and the three-star treatment offered by Binghe Academy, he chose the latter. This year, he has applied for the one-way selection of the instructor, and with his progress in practicing the secret method, he has a great chance of passing.

"Brother, have you been notified of the service location?"

"Not yet, but today my top biochemical beast, the Ice Fang Mammoth, has been prepared. Don't worry, with my strength, a mere illusion puppet is no problem."

It seems that he is bragging to his younger brother, but in fact, he is reassuring Zhang's father and mother.

After eating the food that tasted as good as it did in the past few years, Xu Yi said goodbye to his family and set off for the academy, taking a road that has been extremely familiar for three years.

After walking out of the plane elevator and catching the bus on time, Xu Yi will practice the secret method for nearly three hours. The secret method cannot be practiced in such a public place, but the relatively common secret methods are not a problem.

Xu Yi has already mastered the three secret arts of slow ray, ice pressure and extreme condensation armor. Now he is practicing the third-level secret arts that Rong Mingyue gave him after he reached the third level, Frost Breath and Frost Nova, which are both cost-effective general frost-type secret arts, and his real killer is the annihilation ray that the dean secretly gave him.

Three years is enough for Rong Mingyue and Rong Yujiang to understand his radiation properties. Cold radiation is a rare branch of the frost radiation category. The Rong family father and daughter are not very familiar with the specific characteristics. It is still under analysis. However, Dean Rong should have made some breakthroughs, so one day he suddenly gave him this secret method that no one has practiced for decades.

It was this annihilation ray. After trying it, he found that the energy of cold radiation could indeed slowly promote the operation of this second-level secret technique. He had gradually begun to believe that Zhang Chengwen's radiation type was the advantage that Xu Youlin said, because this annihilation ray was surprisingly powerful. Even the frost breath at the same location had to accumulate radiation energy for a long time before it could achieve its effect in an instant...

After getting off the car, Xu Yi found his new bicycle in the parking shed next to the central square and rode to Rong Mingyue's West No. 5 biochemical test hill.

On the second floor of the test hill, in the huge biochemical pool, the owner of the newly prepared ice-fang mammoth had white hair with a hint of blue, two curved and sharp fangs as clear as crystal, a thick long nose and a pair of small eyes.

The broad nose made it look a little silly, and the crystal-colored fangs made the pair of weapons look less terrifying. Unfortunately, the world's use of radiation was too rampant, and wireless communication devices such as mobile phones could not appear.

Televisions and home landline phones all require extremely thick cables to achieve wired communication. The filtering technology used in this process could have been used in some high-end headphones or noise reduction equipment at the airport in the past.

Seeing Xu Yi coming, Rong Mingyue nodded slightly.

"It's better to finish the modulation before you serve. Try to control it with the chip first."

The modulation of the Ice Fang Mammoth used many unique techniques of the Frost Xuanyuan, and even the order of adding some potions was very particular. It was also Rong Mingyue's painstaking work for three years.

Relying on the third-level chip that adds 30% of the attributes of large creatures, Xu Yi's consciousness was easily connected to the Ice Fang Mammoth. His own consciousness was at the demigod level, so it was naturally easy to suppress a third-level creature like the Ice Fang Mammoth.

This will be his main biochemical beast for the next five years. Even if he is promoted to the fourth-level biochemical division, the Ice Fang Mammoth will also be trained to the fourth level. After all, it is not easy to train another one in three years. Once such a main battle biochemical beast is completely killed, the strength of the biochemical division will usher in a long window period.

Of course, Xu Yi is not without any backup. He has trained two giant werewolves in his own biochemical experiment. This kind of creature can barely be classified as a large creature and enjoy the bonus of the second-level chip.

He also trained the two giant werewolves to adapt to his own frost radiation type. This time he plans to use the second-level chip to control another one.

The giant werewolf is not slow, and it is still possible to clean up the miscellaneous soldiers behind the Ice Fang Mammoth.

Seeing that he can control it easily, Rong Mingyue is also relieved.

"This service mission is very difficult."

"Are you finally willing to release the information about the service location?"

Xu Yi's face was grim. The days of comfortable study and cultivation were over. This was a relaxing day that he didn't have in the main world of Blue Star. However, he was a little overwhelmed by the new knowledge he was exposed to every day.

"Yes, have you seen the news about the blockade of the underground track?"

"I only saw that it was suspended and that the top of the tunnel was cracked, but I don't know the details."

"The news from the academy is still blocked very tightly. This service mission is an emergency mission. The Phantom Puppet directly hollowed out the soil and rocks from the ground to the top of the underground track. Now a group of them have poured into the underground track, and the shelters on both sides have blocked the tunnel."

"We need to go to the entrance of the underground track on the third floor?"

"No, the situation has entered an emergency state now. Do you know what the soil and rocks from the ground to the top of the underground track have been hollowed out?"

Even Xu Yifei, a resident of this world, had his pupils shrink slightly: "Is the hollowed-out part so large that the side of the entire shelter is exposed to the attack of the Phantom Puppet?"

"It's not that critical yet. In the situation you said, Shelter No. 76 is probably going to be abandoned. At present, there are only two or three weak points on each layer of the West Mushroom District. Elite teams of biochemists with soil and rock radiation have already gone to reinforce other places with weak wall thickness."

"The seventh floor is the closest to the surface and has the most weak points. You should be sent to guard the seventh floor."

He breathed a sigh of relief. The weak point of the shelter appeared in the West Mushroom District, which was a whole shelter away from the East Mushroom District where Zhang's father and mother were. The two should not be affected.

After being in the biochemist world for a long time, he couldn't help but have a little affection for Zhang's father and mother who had always been kind to him. Gods are human after all!

"It should be the vibration generated when the ground track channel between the two shelters was dug that attracted the attention of the phantom puppet. However, it is also persistent to hollow out hundreds of meters of soil. Humans are still too poor in their ground spying technology."

Rong Mingyue sighed. Her father Rong Yujiang had already gone to the third floor to participate in the attack and defense of the phantom puppets pouring into the channel. The high-level people of the two shelters actually had a little idea about this ground track channel.

But think about it, the main purpose of the ground track interconnection between the two shelters is not to promote the development of tourism, but to enable the other party to come to the rescue quickly once one party is in crisis.

The underground rail technology was also spread from a shelter that was ranked first. The concept promoted by the other party was to share what they had and what they needed and establish a human territory.

This grand concept shocked Rong Mingyue for a while when she first heard it from Rong Yujiang...
