Zhao Feng and Liu Yan were so frightened by the scene in front of them that they gasped, and they couldn't help but lean back tactically.

"Dual-line, third-order ability, the master of wind and water. Zhou Ziyu casually brushed his hair and showed a proud smile to Zhao Feng provocatively.

In Zhao Feng's subsequent questioning, he learned that Zhou Ziyu and Liu Yan automatically gained an understanding of their own abilities when they obtained their abilities, including the level information of their own abilities, although the two of them did not have enough understanding of the so-called "third-order abilities".

Two third-order crystal pupils have cultivated two powerhouses with third-order abilities, which is 18 points, if it weren't for the fact that third-order crystal pupils are too rare, Zhao Feng really wants to form a hundred-person third-order ability legion!

Seeing that it was about to dawn, Zhao Feng also rested and was ready to continue to fight, although Zhou Ziyu and both said that they could help, but they were still rejected by Zhao Feng, because the number of zombies killed by these two people would not be counted in Zhao Feng's side quest, anyway, he could still hold on, so why take two monster robbers?

This night, Zhao Feng only rested for less than three hours.

"Huh, the corpses of the zombies are gone?" Zhao Feng just rushed into the group of corpses and found that the zombies who had fallen to the ground were gone, and after a closer look, there were many more second-order zombies with green eyes in the original 100% first-order zombie group.

Zhao Feng originally thought that zombies would "improve their abilities" by hunting humans, but according to the current situation, devouring the same kind can achieve the same effect, which makes Zhao Feng have a slightly bolder plan in his mind, but before implementing this plan, he must raise the level of the shield.

"Although the second-order zombies can't break through the first-order shield yet, it is estimated that it is because these zombies have just been promoted to the second-order, and their strength has not yet officially reached the second-order, if you want to implement my plan, at least the shield must be upgraded to the third-order!"

"The number of zombies I hunt now has reached 6,419...... Enough is enough!"

Zhao Feng retreated into the shield, and then directly sacrificed the Nine-Fold Heavenly Tower, and his body was incarnated into it.

It took more than ten minutes, counting the previous income, with a total of 13,228 first-order crystal pupils in stock, and all of them were exchanged and recycled, and 6,614 points were obtained, and the account point balance was 43,824.

"Ding! Do you spend 600 points to upgrade the first-order energy shield to the second-order? After the level is upgraded, the energy consumption of one day will be deducted again, and the shield will be completed again, and 40 points will be consumed. ”

"Can I go directly to the third level without deducting 40 points?"

"Ding!No, do you want to spend an extra 1100 points to upgrade to the third order energy shield? ”

"It's really black!Directly promoted to the third order!" Zhao Feng gritted his teeth, for the sake of long-term planning, it was necessary to improve this time.

At this time, the energy shield changes from white to turquoise and then to blue, and 1900 points are directly deducted, and 160 points must be consumed every day to maintain the shield.

The third-order energy shield can withstand third-order attacks, even blue-eyed zombies can't break it!

"Don't worry about the shield being broken by zombies in a short time, now you can concentrate on killing monsters!"

Zhao Feng's idea is actually very simple: to feed the war with war and feed the corpse with corpses, as long as he specializes in killing first-order zombies in battle, so that second-order zombies will accumulate more and more, and wait until the number of second-order zombies reaches a certain level, and then start hunting second-order zombies, so that second-order zombies will devour each other, and there is a high probability that third-order zombies will be generated.

A third-order zombie may add two survivors with third-order abilities to the City of Hope, and if things go well, maybe a third-order ability army can really be formed!

Moreover, the trial branch of the Yitian system does not consider the zombie level when counting, that is to say, no matter how many zombies are killed, they are all counted as one, and in order to maximize the benefits, it is also the best policy to give priority to hunting first-order zombies.

In order to continue to maintain the zombie siege, Zhao Feng put dozens of Nokia 6300 into the city, singing around the clock, and the zombies gathered increased instead of decreasing, and the second-order zombies gradually increased, and even the second-order zombies began to fight with each other.

Second-order zombies are more sensitive and obsessed with blood, and tend to give priority to devouring flesh rather than attacking lifeforms, and when two second-order zombies target the same corpse at the same time, they will fight each other, and eventually evolve into fighting each other, until one of them devours the other......

Finally, at 3:17 p.m. on the third day.

"Ding! Trial Branch: Zombie Hunting has been completed, the total number of hunts is: 67139, 100% completion, and 67139 points will be obtained!"

"Ding! The trialist completes an additional challenge item, with an additional completion rate of 571.39% (regarded as the upper limit of 500%), and an additional additional trial equipment reward, ninth-order exclusive trial item, and the corpse refining tripod!" (the exclusive trial item can only be used in the trial space, and cannot be shared with reality and other trial spaces, and is bound to the trialist)"

"Ding! The exchange function can recycle the Corpse Refining Ding and return one million points, is it recyclable?"

The system prompt ended, but Zhao Feng was confused.

"What's the situation now? After the system has issued the reward, it has to use one million points to take it back? What is this corpse refining tripod? It can make the system so 'panicked'?" Zhao Feng immediately withdrew to the shelter, and then took out the corpse refining tripod, a bronze square tripod that could just be placed on the palm of his hand, with two ears and four legs, and a hideous ghost-faced totem on the tripod's body, which was rusty and evil.

Corpse Refining Ding: Condense and refine the qi of the dead.

"That's it? No more introduction?"

Zhao Feng was stunned, the introduction of this prop didn't even indicate how to use it.

"System, how do you use this thing?"

"Ding! The Corpse Refining Ding needs to be driven by spiritual power! Do you want to recycle the Corpse Refining Ding?"

Faced with the system's second recovery inquiry, Zhao Feng hesitated: if he really wanted to use spiritual power to urge, it meant that the Corpse Refining Ding could not be used until he completed the main line of the trial, but if he recovered the Corpse Refining Ding now, he could directly have one million points!

Points can be used practically, and one million points can greatly boost and advance the progress of the main story, Zhao Feng can even exchange unlimited props of various Yi Tian cards to equip his team, even if he dominates the world, it is not impossible to do it.

But the Yitian system twice said that it wanted to recover the Corpse Refining Ding, which made Zhao Feng suspicious: If this Corpse Refining Ding was really so important to the system, why would it be issued as a reward?

After thinking for a long time, Zhao Feng looked at the group of corpses outside the shield, and a bold speculation appeared in his mind: the corpse refining tripod was not issued by his own Yitian system!

The Yitian system is not the only one, in addition to the set that Zhao Feng himself has, there is another set in the current trial space, if the latter is called the "end time system", then Zhao Feng is likely to complete a certain task of the end times system while completing the side tasks of the Yi Tian system, but the end times system cannot cross the Yi Tian system and directly give Zhao Feng a hint of issuing rewards, so the refining corpse tripod was issued as a reward through the Yi Tian system.

If things were really as Zhao Feng had speculated, then the long-term value of the Corpse Refining Ding would probably be far above one million points, otherwise it would not have made the Yi Tian system so eager to recycle it.

"Anyway, I'm not in a hurry to expand now, more than 100,000 points are enough for me to operate for a while, even if I change a million points, it's just a matter of accumulating in my hands and looking cool, and when it really comes to the critical moment when I want to use a large number of points, it's not too late to change it!" Zhao Feng smiled and casually threw the Corpse Refining Ding into the earth and sky.

"Ding! Automatically get the trial branch: Challenge the strong: Please hunt a fifth-order powerhouse within forty-eight hours, complete it to get a chance to draw a random lottery, and if you fail, you will recover the corpse refining tripod!"

"Do you want face in the system? Playing scoundrels so bluntly? Retaliating to issue tasks, right? Shameless and a little reserved, okay?" Zhao Feng was so angry that his teeth itched, although the lottery function had already come out, but Zhao Feng had never believed in this kind of luck, so he had not spent points to draw a lottery, but in fact, only five hundred points were needed to conduct a random lottery.

Hunting a fifth-order powerhouse, if you succeed, there is only one lottery, and if you fail, you can directly recover the corpse refining tripod.

This full of malice is coming to the face, how can people not be angry?

Zhao Feng wanted to take revenge on the system, but he found that he couldn't, unlike the first day when he had nothing in this apocalyptic world, now he took on the role of a guardian, once he gave up all this, he just returned to reality, and there was no damage, but those who were protected by him would suffer calamity.

"I'll put up with you first! Don't let me get a chance to retaliate back! Scorpio's hatred, you can't afford it!" Zhao Feng silently kept this hatred in his heart.

Although the strength of the fifth-order powerhouse must be far greater than the current Zhao Feng, the latter still has a hole card, so it is not hopeless, it's just that in the huge doomsday world, third-order zombies are already rare, and the fourth-order is even rarer, and the fifth-order represents the highest level in this world.

"The boat will naturally go straight to the bridge, now it's better to collect a wave of vegetables first!" Zhao Feng put away his displeasure and set his eyes on the second-order zombie group, he was ready to completely finish off the remaining zombies today.

It is as strong as the Nokia 6300, and the power has been exhausted at this time, and the number of zombies outside the shield is no longer increasing, and among the nearly 20,000 second-order zombies, only a few dozen scattered first-order zombies are shivering.

Zhao Feng rushed into the corpse group with the golden sword, the second-order Broken Gold Taidao could no longer play a role in the second-order corpse group, he returned the Taidao to Liu Yan, but still did not let Liu Yan and Zhou Ziyu join the battle.

Although the branch has been completed, killing zombies has a chance to obtain the level experience of basic attributes, if you fake others will not be able to obtain it, the previous 67,000 first-order zombies made Zhao Feng's five basic attributes break through level 20, which means that his current basic attributes have more than doubled compared to when he first came to the trial space!

Just as Zhao Feng was harvesting vegetables, west of Dazhou District, which is next door to Kyushu District, the road leading to Yongchun District was blocked by a broken bridge.

And Qin Siqi and his group, Xiao Jun and his group, and the rest of the survivors who wanted to go to the peaceful military fortress were all blocked on this side of the broken bridge.

Under the broken bridge, the river was turbulent, and there were fish shadows in the river, and there was a light purple in the shadows......
