With the rotation of the concentrated energy vortex, the injuries in Qi Lin's body gradually recovered, he held the heavy eight-sided golden gourd, and looked at the No. 5 sample that did not choose to take the initiative to attack dozens of meters away, and couldn't help but fall into thought.

In the field of defense and aggravation, these two abilities can be said to complement each other, with the cooperation of the two, the melee ability of this No. 5 sample is too powerful, and only a long-distance attack in the energy form that is almost not affected by gravity can cause effective damage to it, in addition, whether it is bullets or arrows, the power will be greatly weakened after entering the gravity field, just like entering the spiritual system ability to create a "sticky zone" with mental power, and when the warhead or arrow comes into contact with the body of the No. 5 sample, Its remaining kinetic energy was no longer enough to penetrate the crystallized skin.

Qi Lin could choose to delay time, but he didn't dare to guarantee that the next No. 5 sample would still lie on the spot like an iron turtle, using gravity to collect, he could completely force Qi Lin into the dead corner of the field, and it would be difficult for Qi Lin to rush out again.

Recalling what I had just felt, the gravity at the closest place to Sample Five was about ten times the force, and anything in this area would be under pressure ten times its own weight.

You must know that when the rocket is launched, the astronauts in the superweight state only need to bear the gravitational acceleration of 4-7 G, even if it is the Huaxia astronaut training base, which is known for its strictness, the centrifuge in the superweight training room will only give the astronauts at most eight times the gravitational acceleration, which is almost the limit of normal human beings.

Ten times the gravity force is enough to crush those ordinary people, even if it is an extremely strong evolutionary, if you are in this state for a long time, all kinds of damage will inevitably occur to various organs in your body.

In this tenfold gravity realm, it is very difficult to stand up straight, let alone perform various attacks.

Qi Lin roughly estimated that he would need to increase the speed of the shaped vortex to 3,500 revolutions in order to move freely in the tenfold gravity field and leave enough room to react to sudden changes in gravity.

3,500 rpm ...... This is more than twice the normal speed, but this can only make Qi Lin become like an unaffected ordinary person in the ten-fold gravity realm, and if you want to bring a heavy eight-sided golden gourd, then I'm afraid this number will have to increase by a few hundred revolutions.

Against such an opponent, the heavy eight-sided gourd was clearly not an ideal weapon - it weighed a full fifty kilograms, and with ten times the gravity, it weighed half a ton......

Under the influence of the gravity realm, Qi Lin's strength advantage as a high-level evolutionary was gone, and this half-ton weapon was simply a burden.

At this time, the lighter the weapon, the more convenient it is to use, but another problem immediately arises - lightweight weapons, such as daggers and daggers, will not be able to hurt the extremely high-defense specimen of the fifth at all.

The crystals condensed on the body surface of the No. 5 sample should be a kind of corundum, and the Mohs hardness has reached level nine, unless Qi Lin can get a drill bit made of diamond, otherwise if he wants to penetrate this crystal layer, he will definitely not be able to do it with the cold weapons provided by the organization.

"It's really an iron turtle...... There is no way to start...... "He has already figured out the range of the gravity field of the No. 5 sample, and the farthest distance can reach fifty meters, Qi Lin stepped on this boundary line, constantly circling around this "iron turtle".

Gravity limited the power that Qi Lin could burst out, and the crystals provided perfect protection for the other party, and for a while, Qi Lin couldn't think of an effective countermeasure.

At this moment, Sample Five finally lost his patience, he stomped his foot hard, and the entire Colosseum trembled slightly, and then, he slowly pressed towards Qi Lin.

"Sample Five is starting to take the initiative!" The smile on Abel's face became brighter, "And this challenger, who relied on the help of drugs to defeat the No. 2 sample, seems to have thought of a way to fight the No. 5 sample until now, I'm afraid this battle test will end early-"

However, Abel didn't see it, and just as the fifth sample began to move, Qi Lin's eyes flashed with a glimmer of light.

Figured out a way!

Just when Sample No. 5 raised his feet and stomped on the ground, and the vibration spread throughout the Colosseum, Qi Lin suddenly thought of a story he had heard before-

At the beginning of the 19th century, when a group of Napoleon's soldiers crossed a bridge in Angers, France, at the behest of an officer, the bridge suddenly shook strongly, and then broke and collapsed, and a large number of soldiers and onlookers fell into the water and unfortunately died.

This is not some kind of slag project, with the structure of the bridge, even if it carries ten times the number of soldiers, this situation will definitely not occur, after investigation, the culprit of the bridge breakage is the uniform pace of those soldiers when crossing the bridge.

Resonance.

When the soldiers were marching, the rhythm and frequency of the steps coincided with the natural frequency of the bridge itself, resulting in resonance, which caused the vibration of the bridge to be strengthened geometrically, and the amplitude instantly exceeded the limit that the bridge could bear, which led to the accident.

The soldiers' steps can't break the bridge, and the bridge itself won't collapse for no reason, but when the frequencies of the two are the same, the two can be considered the same physical system, and the kinetic energy in the system will be stored and then released through resonance instantaneously, causing massive damage.

Similarly...... If Qi Lin could know the frequency of the crystal layer on the surface of the No. 5 sample, and then use the same frequency to knock it, he could easily crush the indestructible crystal layer by using resonance!

"Frequency...... Frequency is key! ”

Thinking of this, Qi Lin immediately put down the eight-sided golden gourd, and then empty-handed, pounced head-on on the No. 5 sample that was pressing towards him.

"Oh my gosh...... What did the challenger do? He discarded the weapon in his hand! Obviously, he was doing the right thing, but it was also a last resort, and in the powerful gravity field of Sample Five, the heavier the weapon, the more difficult it was to exert its power...... However, what threat can an empty-handed challenger pose to Sample Five? ”

As the distance decreases, the gravitational force felt by the body increases dramatically...... Five, seven, nine...... And along with gravity, there is also the rotation speed of the shaped energy vortex in Qi Lin's body......
