With Chen Chu's current strength, even if he encounters a Three Heavens believer, he can kill him, and the Three Heavens rebel practitioners can also deal with them with more than one hundred points of agility.

Therefore, there is no urgent need to improve combat power. Of course, these attribute points cannot enhance anything.

On the contrary, he has always been somewhat uneasy about defending himself.

He was most afraid of being targeted by the rebels' sniper rifles, especially the anti-material weapons equipped with armor-piercing bullets, which had a firing rate of several times the speed of sound and were enough to penetrate 20 mm thick steel plates.

If he is targeted by the enemy during the battle, he may not be able to react even if he senses the danger in advance.

The two battles we encountered were not bad. The enemy used conspicuous weapons such as rockets to launch surprise attacks, and their speed did not give the enemy a chance to shoot a second time.

But what about next time? After all, freshmen like them are easy to be targeted first.

Thinking of this, Chen Chu placed his hand on the armor, and a voice sounded in his mind, "Consume 2 attribute points to strengthen the armor."

As Chen Chu's voice fell, the remaining attribute points on the attribute page became 6. At the same time, an invisible force enveloped the black and red armor.

Silently, the armor seemed a little darker.

It looked like the armor hadn't changed much, but when Chen Chu picked it up, he found that the armor had become thicker, giving him a sense of solidity.

Dong Dong! Chen Chu tapped his fingers on the light armor, making a low sound.

Only strengthening 2 points of attributes did not change much. Chen Chu pondered for a moment, and the voice continued to ring in his mind: "Use all attribute points to strengthen the armor."

Buzz!

When six attributes were enhanced at once, the air around the armor made a faint humming sound, and a faint luster flashed across it.

After this enhancement, the surface gloss of the armor is slightly dimmed, giving people a sense of depth. In addition, the overall internal structure of the armor seems to have undergone subtle changes.

Fortunately, the appearance has not changed much, there is just a slight sense of oppression. This change seems normal under the blood and fire of the battle in the past few days.

Just as Chen Chu was looking at the enhanced armor, two rows of transparent text appeared in front of Chen Chu.

"A full body armor made of common alloy soft steel wire, with a current solidity attribute of +8, a common extraordinary item, and good defensive power.

The surface alloy can resist ordinary sniper bullets, the internal steel wire can prevent penetrating injuries from armor-piercing bullets, and the helmet can resist attacks from sniper armor-piercing bullets. "

"Note: Due to material limitations, the maximum strength of this item can be enhanced by 10 points. If you want to further improve the quality, you can choose to incorporate high-level materials."

"It was actually directly enhanced into an extraordinary item." Chen Chu showed satisfaction on his face.

The effect of the enhancement did not disappoint him. His body parts could resist sniper bullets, so he finally didn't have to worry about being attacked by a sniper rifle.

Moreover, this enhancement is a bit similar to enchantment, and the overall appearance does not change much.

At this moment, Chen Chu looked at the straight knife on the table, thinking: "The defense enhancement effect is so good, then where is the knife?"

The F-class straight knife is characterized by its sturdiness and its sharpness is actually not much different from that of an ordinary steel knife.

If the attribute points were used to strengthen it to the point where it could cut through iron like mud, a cultivator from the Third Heaven might be cut in half along with his weapon if he wasn't paying attention.

But he just thought about it for a moment and Chen Chu shook his head and put it behind him.

It is too early to consider these things now, it is better to improve his cultivation to the third level first. By then, with the physical enhancement continuously provided by his clone, he will be among the strongest in the third level.

Next, Chen Chu sat cross-legged and began to practice the Dragon Elephant Skill...

Um?

After practicing the technique for only two rounds, Chen Chu exclaimed in surprise, because he found that the effect of practicing here was very poor. The concentration of supernatural energy between heaven and earth was too low.

If the concentration of extraordinary energy in Wujiang City where I was originally located was 10, then here it might be only 1 point.

Chen Chu slowly opened his eyes and frowned slightly: "Is this the reason why Lao Xia said the training environment is too bad?"

But the question is, on the same planet, why is the concentration of supernatural energy so low here, while it is so high in Dongxia?

Chen Chu was a little confused for a moment.

"Oh, right." Chen Chu suddenly thought of something, took out his phone and opened the trial class group, and sure enough, he found that some classmates were also talking about this issue.

At the same time, the authorities have already prepared a solution.

When we set out in the morning, Pang Long said that he had sent out a list of advanced resources that unlocked permissions, among which was an energy crystal that could only be exchanged at the fourth level.

Unlike life crystals from mutant beasts that can strengthen the physical body, energy crystals are pure collections of energy that come from special mineral veins.

It contains pure energy, which can be absorbed by practitioners to speed up their practice, or used to quickly restore their true strength. Apart from this, it has no other effects.

But due to its scarcity, this crystal is a strategic resource and can only be exchanged by those who belong to the official forces and have reached the fourth level.

And this time the authorities were very generous. They only needed five points to redeem one energy crystal that originally required fifteen contribution points, which was equivalent to a 30% discount.

And considering that these freshmen do not have enough contribution points, they can also buy on credit.

However, each person can only redeem two coins per month. If more than that, the price will return to normal. However, under normal circumstances, a Second Heaven cultivator cannot use up the energy of one coin in a month.

After reading the information about the energy crystals, Chen Chu flipped through the list again and even found the blood of a giant beast on it, but the contribution points required to exchange it were too many.

Moreover, for him, no cultivation resources can compare to the attribute points transformed by life crystals.

After flipping through the pages for almost half an hour, Chen Chu put down his phone and prepared to go to the logistics department to buy an energy crystal on credit after dinner.

Seeing that it was still early, Chen Chu's consciousness sank and he came to the heavily armored beast.

At the bottom of the river where the water rushes into the sea, a ferocious black beast slowly raised its head from under the mud and sand, and exerted a little force with its limbs, stirring up rolling mud and sand.

A month later, the heavy armored beast became more and more ferocious and massive, with thick and sharp limbs. From a distance, it looked like a lizard or crocodile covered in heavy armor.

At the same time, as it continued to kill, a fierce and violent aura gradually surrounded it, and many small fish and shrimps were scared away as soon as they approached.

For example, now, as the heavy armored beast swam by, two one-meter-long "small fish" at the bottom of the muddy river were suddenly frightened, and in an instant they swung their tails and rushed out more than ten meters away.

Fortunately, the heavy armored beast disdains to eat these ordinary fish. It just glanced at them with cold eyes and then continued to look for those mutated ferocious fish.

In the evening, Xia Youhui, sweating profusely, opened the door of his room and looked at Chen Chu, who was sitting cross-legged in front of the window. He thought that Chen Chu was practicing and shouted, "A Chu, go eat."

"Is it time for dinner?" Chen Chu slowly opened his eyes.

The two of them came to the restaurant on the third floor one after the other. Chen Chu found that those classmates were all sweating, as if they had experienced some fierce battle.

After preparing the dishes and sitting down with the meal tray, Chen Chu asked curiously, "What were you practicing this afternoon? It felt like you had been fighting for three days and three nights."

"The concentration of extraordinary energy here is too low, and the improvement through meditation is too slow."

Xia Youhui ate his meal in big mouthfuls, and said in a fuzzy voice: "So we spent the whole afternoon sparring against each other to gain practical experience. We fought like this for the whole afternoon."

It seems that everyone is the same.

Xia Youhui suddenly said: "By the way, Ah Chu, have you seen the list of resources in the trial group, such as the energy crystals that can speed up our cultivation?"

"I've seen it." Chen Chu said as he took a bite of ordinary mutant beast meat.

Xia Youhui nodded: "It's good that you have read it, but I don't recommend you to exchange it."

"Why?" Chen Chu paused.

Xia Youhui whispered mysteriously: "Just trust me, eat quickly, and I'll show you something nice when we get back."

"What good stuff?"

"You'll know in a moment, don't worry, brother, I won't lie to you."

"Okay..."
