I submitted my mathematics to the country and won 500 million yuan

In the urban area, at the entrance to the basement where freshman was living, a bright moon that looked like frost and snow shone brightly, blocking all incoming rocket spells.

The roar of the explosion was endless, the reinforced concrete continued to collapse, and even the bright moon became a little dim, but it still remained strong and did not dissipate.

However, in the explosion of the rocket, there were also artillery shells made of solid steel that rushed into the basement. After the artillery shells, there were machine gun bullets that followed closely.

The seven flying swords composed of the Big Dipper array firmly locked onto the incoming cannonballs, knocking them down every time.

As for the remaining bullets transformed into machine gun spells, the four super-order magic arrays hosted by Chen Bixiao and Wang Ling'er were responsible.

After several days of actual magic combat, and with Chen Bixiao's strength no less than that of the Great Mage, it was easy to create the super-level magic circle, and Wang Ling'er's assistance was no longer needed. Wang Ling'er has recovered a bit mentally since she has rested. With the help of Chen Bixiao, she can manage the super-level magic circle that has been drawn up. Although it is a bit difficult, she can manage it.

For a moment, fireballs, earth shields, wind belts and water waves blocked the bullets rushing into the basement, forming the last line of defense.

However, even so, the number of first-year students is rapidly beginning to decrease. And only half a minute later, Junior gathered another group of reinforcements, bypassing the basement entrance and directly began to attack the roof of the basement.

The sound of explosions suddenly came from above the basement, and many basement roofs began to collapse at the same time. More machine gun spells emerged from the collapsed basement roofs.

Large swaths of bullets flew along the collapsed roof hole. In just a few seconds, more than 30 freshmen students were eliminated.

Li Tuyuan immediately discussed with Chen Bixiao, Wang Ling'er, and Tang Yuan and Liao Qian from Sanqing University: "The junior students are all in the True Yuan realm, and it is impossible to save all the classmates. The only way now is to make Qi Refining Dzogchen." Retreat from the tunnel, leaving all other students behind."

In the short time that Li Tuyuan was speaking, more than a dozen freshmen students were struck by bullets and eliminated from the competition. As the number of students in the group formation decreased, the bright moon transformed from the frost and snow meteor array and the flying sword transformed from the Big Dipper array became a bit dim.

A cannonball immediately broke out of the blockade of the two formations. Chen Bixiao, Tang Yuan and Li Tuyuan jointly blocked it. Chen Bixiao and Tang Yuan were shocked on the spot and retreated continuously. Li Tuyuan was even more shocked on the spot. Flying, almost triggering the safety circle.

And this is the result of the cannonball being weakened by two large formations!

The strength of the True Yuan Realm is too terrifying, and the True Yuan Realm in the junior year will only gather more and more, and the freshman will not have any chance to survive in the competition field.

Even if all the students in the late stages of Qi Refining were to be used as cannon fodder to hold back the junior, and the Qi Refining Dzogchen escaped from the river, they would only be able to struggle for a few more minutes.

But the current situation is either to annihilate the whole army immediately, or to allow Qi Refining Perfection to survive for a few more minutes, and the fierce offensive of the third year will not give the first year any time to discuss and hesitate.

Sanqing University was the first to take action. All the students of Sanqing University used their full energy to activate their Qi. The bright moon transformed by the frost and snow meteor array became a little brighter again, firmly blocking the rockets that entered the basement from the front.

And taking advantage of this moment, the 12 Qi Refining Dzogchen players from Sanqing University who were still on the field floated 10 centimeters into the air and quickly flew towards the previously excavated tunnel leading to the river.

Tang Yuan was startled. It was not him who arranged the retreat of Sanqing University, but Liao Qian. After leaving Zhu Zihang, Liao Qian has obviously changed a lot in the past few days. Together with Tang Yuan, she cooperated with Kou Xinghe to coordinate the offense and defense of Sanqing University. Unexpectedly, she decisively carried out Li Tu Yuan's order at this time.

Liao Qian was still standing in the frost and snow meteor formation at this time, with no intention of leaving, but there was a bit more determination in her eyes. It seems that even if Zhu Zihang is not here, she will still do her best.

Chen Bixiao hesitated for a moment, not because she was hesitating whether Imperial University should evacuate, but because she promised Li Zheng to take good care of Wang Ling'er on the first day of the competition.

But if Wang Ling'er is taken away at this time, the morale of the few remaining students in the college alliance will inevitably drop to the bottom. After all, the University Alliance is different from Sanqing University and Imperial University. There is no Qi Refining Perfection in the entire University Alliance. Students at Sanqing University and Teito University still have a sense of campus honor and are willing to be cannon fodder for the top graders. Once the college alliance realizes that it has been abandoned and no longer actively cooperates with the group formation, the entire freshman defense may collapse in an instant. .

But Chen Bixiao herself is the one who should be evacuated the most. If she is eliminated here, it will be a waste of 2000 points in her junior year!

For Chen Bixiao, the best thing to do is to evacuate from the river, and then use his 2000 points to divert the main force of Da San, giving other Qi Refining Da Perfects a chance to escape.

At the same moment, Wang Ling'er took the initiative to take over the leadership of the super-level magic circle. Her face, which already had very little mental energy left, turned even paler, and even her body trembled a bit. Fortunately, there were others in the college alliance. The students with magic talents shared their burdens to prevent the super-order magic circle from immediately collapsing.

The students of the College Alliance also collectively input a large amount of infuriating energy into the group formation in the next moment. The Frost and Snow Meteor Array, the Big Dipper Formation and the Super-Order Magic Array were all a little brighter, showing the determination of the students of the College Alliance.

Chen Bixiao also understood Wang Ling'er's meaning at this moment, and immediately asked Imperial University's Qi Refining Dzogchen to evacuate immediately following Sanqing University.

Chen Bixiao didn't waste any more and quickly flew towards the entrance of the tunnel. At the same time, Wang Ling'er's words came out: "Don't underestimate the college alliance!"

The voices of other university alliance students also came:

"Being able to reach this stage and still be able to compete with the True Yuan Realm, I have no regrets in this competition."

"Our cultivation is not as good as yours, but we can still hold back the True Element Realm!"

"You genius monsters, escape here and come back!"

……

The freshman's burst finally suppressed the junior's attack for a few seconds, and the freshman's Qi Refining Perfection all entered the tunnel leading to the river.

But at this time, losing the support of more than 20 Qi Refining Dzogchen, the light of the Frost and Snow Meteor Array, the Big Dipper Array and the Super-Order Array dimmed at the same time.

The shock wave of the rocket explosion, the unparalleled impact of the artillery shells, and the machine gun fire caused the freshman students to immediately trigger a large safety circle. In just 10 seconds, there were only dozens of freshmen still on the field.

Chen Bixiao clenched her fists slightly in the tunnel, and through meditation she clearly perceived the freshman year's situation.

At this time, there are only a few students at the 9th level of Qi Refining left in the college alliance. Sanqing University and Imperial University each have about a dozen students at the 9th level. Even Liao Qian has been swept out of the competition. To Chen Bixiao's surprise, Wang Ling'er was only knocked away and not eliminated.

At this moment, two strange auras suddenly erupted from the remaining freshman students. One of them was very familiar to Chen Bixiao. It was the aura that broke through the Great Perfection of Qi Refining in the later stages of Qi Refining. It came from Li Tuyuan of the Border Guards University. The other one came from Wang Ling'er. It was the aura between heaven and earth that began to gather and spontaneously transformed into magical energy, which completely violated the second law of source mechanics!

However, at this time, Chen Bixiao was staring blankly at the front of the tunnel. The Qi Refining Dzogchen who had just left had gone and returned, and the person who walked to the front was a familiar figure.

Chen Bixiao felt many emotions in her heart, and finally smiled: "Great Demon King, you are finally back."
