The second step is stress testing.

It is divided into two steps: external pressure test and internal pressure test.

External pressure is to use external force - a hydraulic metal clip that can freely control the pressure area and the size of the pressure, so as to compress the bionic lungs from the outside to the inside by hitting, pressing, heavy pressure, and continuously increasing the pressure.

There are many ideas to resist external pressure.

Helenberg's group used hexagonal honeycomb alveoli to evacuate pressure, and diverted the pressure of the focus point to the surrounding alveoli, so that the bionic lungs were subjected to even force. At the same time, it increased the internal pressure of the small alveoli around the lungs to hedge against the external pressure.

Xia Zuomoto thought that this structure of bionic lungs would definitely get the first place in the external pressure test.

However! The results of the external pressure test were somewhat unexpected.

The one who won the lead was the Burning Fire Salamander Group.

Helenberg was also a little surprised. He frowned and thought about the anatomical diagram of the burning fire salamander he made for a long time. He couldn't figure out how the group did it.

Fire salamanders are common in volcanoes.

Adanavados looked at the Metal Cube Team, "Start with you."

The bionic lungs of the Wind Cannon Demon Frog Group are like nested balloons. The outermost alveoli falls off after being injured, and the inner alveoli grows larger, becoming a new outer alveoli.

This assessment will use [Sharp] magic bullets with a power of 150 points to shoot the bionic lungs, fire three shots in a row, and each shot aims at the key points of the bionic lungs.

Adanavados stroked his beard and thought for a second, and finally approved the other party's request.

At 220 o'clock, this number moved everyone present.

The elemental puppet brought a 1-energy pistol, and fired a shot after a short charge.

The live demonstration of the bionic lung trauma testing session and the introduction of additional functions will become the best publicity materials and will be spread throughout the alchemy school through the mouth of the outer palace master!

For bionic bodies, air is just one of the gases that need to be sucked into the body.

"Clang~"

The spring-like bionic lungs have poor internal stability and are easily pierced by magic bullets from the bottom of the sphere. The bullet hits the top cover of the culture tank for three crisp sounds. After staying for a short period of time, the energy is exhausted and dissipated.

But they still failed to get first...

The elemental servant randomly selected one side to shoot, and three bullets stuck in the depths of the metal cube, failing to penetrate the bionic lungs.

The male leader of the Metal Cube Team, wearing a straight alchemist robe, stood up from the chair and carried a metal box to the center of the venue.

The bionic lungs of the Burning Fire Salamander Group rotated the lung lobes and turned the spring-shaped lungs into a side, allowing the alveoli, which was originally located on the medial side to the outside, in order to replace the damaged alveoli to withstand a fatal blow.

Adanavados nodded, waved his finger and summoned an elemental servant to help Helenberg control the cultivation pot.

The burning fire salamander is a demonized fire salamander.

The next one is the Wind Cannon Demon Frog Group.

"Silver-eating insect, a kind of insect-like monster produced from the territory of mineral alchemists - the Kingdom of Waste Hammer." Liszt introduced:

"The insect feeds on metal objects, and the feces excreted are also metal objects.

"After sucking enough air, the Magic Whale Zero will be able to withstand a magic bullet with 220 power."

Helenberg was pushed back by the impact force a few steps, and then stood on the heel and said, "Come again."

The bionic lungs of the Metal Cube team do not have an autonomous repair function, and this link does not allow manual replacement of damaged metal squares. They can only use damaged metal cube alveoli to participate in the test.

Leonardo Liszt, member of the Association of Alchemists of the Wilderness.

At this time, the bionic lungs with self-help repair function stood out.

"Bang, puff!"

The Wind Cannon Demon Frog Team was lucky. When all three bullets penetrated the outermost lung lobe, they were deflected by the airflow and hit the culture tank.

The culture tank is placed from vertical to horizontal posture.

There are nearly a hundred alchemy bionic systems inside the bionic body, and more than half of them need to regularly inhale specific oil and mist to supplement consumption in the bionic system or maintain the bionic system.

Helenberg bowed to the judges for the third time and begged Master Adanavados to let the elemental puppet attack him.

The sound of rolling metal particles sounded from the metal cube, like someone was shaking violently the metal box containing steel balls.

The Burning Fire Salamander team brought the damaged bionic lungs and left the venue in disgrace and left the assessment hall.

Lister's group solved the biggest defect in the bionic lungs of the metal cube and became the group that is most likely to qualify among the three groups.

Volcanoes themselves are the product of high pressure, and volcanic eruptions are the appearance of pressure explosion in the earth's crust.

Theoretically, if several layers of balloon-shaped lung lobes are nested, there are only a few chances of deflecting the bullets.

This is the additional function, a special ability that can cast a wind ball without wind spells.

"Due to the appearance of the bulletproof vest, the rebooted vest can only withstand blunt or sharp attacks below 100 power points."

They want to take this opportunity to announce that starting today, in addition to the method of repairing metal props, the method of independently repairing metal props is also developed by the Huangtou Alchemist Association.

On the bionic lungs of Helenberg's group, the large alveoli proliferated new small alveoli to replace the damaged small alveoli.

"But I don't think it's enough!"

"I'm honored to show you the additional functions of the Bionic Lung of the Magic Whale Zero" Helenberg walked to the center of the long, first made some polite comments, and then said:

The nested bionic lungs of the balloon will form outward wind pressure after the outer lobe explodes, which can offset the impact of some bullets and even deflect the bullets outward.

"The bionic lungs of the Demon Whale Zero, jointly developed by Xia Zuo and I, can proliferate up to 13,000 small alveoli without severe damage."

However, the inherent stability of this lung structure is not as good as that of a tiger-headed demon whale.

But...their festiveness was ended by the Metal Cube Team.

The Huangtiao Alchemist Association sponsored the Lister group to participate in this bidding, which is not just as simple as revealing the bionic lungs of the No. 0 Rubik's Cube.

Helenberg bowed slightly to the judges again and applied to fire a magic bullet with a power of 300 points.

Xia Zuo saw the scene inside the Rubik's Cube, and countless silver-eating insects were spitting out silver silk threads, weaving small metal squares like spiders weaving webs, as well as the air pipes, air pumps and air bags inside the squares...

This link will only test bionic lungs with energy transfer rate of 0%, because bionic lungs with energy transfer rate of 100% are too expensive..

Trauma test is divided into more than a dozen small steps, such as abrasion, impact, scratches, etc., and when we enter the last step to test the resistance of the fatal blow, each bionic lung is already scarred.

"Dangdangdangdang~"

"puff"

After several seconds of accumulation, the balloon-shaped bionic lungs will be stacked with pressure layer by layer through multi-layer nesting structures, so that the wind ball with a powerful power of up to 110 points is accumulated in the lung lobe at the center.

"puff!"

At Helenberg's request, he developed the same amount of bait as a backup.

This is a pre-service that fully considers the expansion of physical functions for customers, allowing Helenberg's team to get more scores in the phase test.

After Liszt came on stage, he first greeted the judges and other groups politely, then opened the cultivation tank and turned the damaged side of the metal cube up so that the people around him could see the next scene clearly.

Shazzo and Helenberg looked at each other and saw the solemn expression in each other's eyes.

The yellowish-colored bullet drilled into the bionic lungs, carved out a huge cavity, and stopped 1 cm from the large alveolar inside.

During the internal pressure test, two gas pipes hang down from the top of the culture tank, connected to the bionic lungs, and continuously injecting air into it.

After hearing his guess, Xia Zuo secretly smacked his tongue... Sure enough, when bidding involves, the tragic level of the inverter will be without ceiling restrictions...

Helenberg bowed slightly to the reviewer, "Please allow me to use the cultivation tank to inject air into the Demon Whale Zero."

The Wind Cannon Demon Frog, like its name, cannonball-like wind balls to attack the enemy.

It took 22 minutes to repair the metal Rubik's Cube.

The elemental puppet retracts the element energy pistol and stops shooting.

"Due to the special material and structure, this bulletproof vest cannot be repaired for the time being. We can only pick out materials with recycling value and use them again, and weave them into a new Magic Whale bulletproof vest."

It's Helenberg's turn to team.

"Everyone, the bionic lungs of the 'Rude Cube Zero' developed by our group have a unique battlefield repair function."

"puff!"

The elemental servant began to charge the Yuanneng rifle... The yellowish-colored energy poured into the magazine and gathered into three yellow magic bullets...

"Puff puff puff!"

"Bang." The magic bullet hit the vest and smashed a clear depression. The bullet bounced to the ground and rolled down twice, then disappeared.

"Clang~"

To be honest, according to Xia Zuo's understanding, this additional function may become a deduction for the Wind Cannon Demon Frog Group

The Alchemy School specifically requires the development of bionic lungs with an energy transmission rate of 0% in order to prevent Nyoxat from being aggressive.

The Wind Cannon Demon Frog team was better, and directly placed an offensive method with no energy fluctuations and difficult to detect in the bionic lungs, which violated the original intention of the Alchemy School.

After becoming the second-placed three consecutive sessions, Shazzo and Helenberg saw hope of winning the championship in the trauma test session.

"Bang, bang, bang, bang"

"We can use wind energy to charge the internal pump air array, inject air into the vest, or use wind spells."
