At the same time, other apprentices also completed the challenge one after another.

Most of them failed, and only a few at the top successfully completed the fourth level challenge. However, there were only two who could complete the challenge without any damage, namely Li Qing and Zhang Jishan.

Although Cao Wenyuan, Gongsun Jin, Mo Wenxi and Chu Zaizhong completed the fourth level, they each had their own losses.

For example, Cao Wenyuan only lost one soldier, but it was still damaged.

The one who suffered the greatest loss was Gongsun Jin, who finally completed the challenge at the cost of losing thirteen infantrymen.

After completing the challenge and opening the divine realm for the troops to go back and rest, Gongsun Jin raised his head and shouted:

"Teacher, I wonder how far Li Qing has completed the challenge?"

The light curtain only shows which apprentices have completed the task and does not show any losses.

After a while, Nie Yang's voice sounded in his ears:

"I know what you want to ask. He has completed the fourth level challenge without any loss. You have lost the bet between you."

"In addition, he is already preparing to start the fifth challenge. I can allow you to return to your own divine domain to replenish troops, up to the maximum population of 50. However, the difficulty of the fifth challenge is very high, and you have no chance. The instructor recommends that you give up the fifth challenge.

Five challenges.”

"Damn it, how could he be so strong?"

Gongsun Jin bit his lower lip, feeling a little unwilling.

"I wonder if the instructor can tell me the specific difficulty of the fifth level challenge so that I can give up completely."

Nie Yang thought for a while, although Gongsun Jin's mental talent was not as good as Li Qing's, it was still four-star. In previous years, he was considered the best in his name, and he was worthy of cultivation.

"The fifth level challenge is 4,000 skeleton undead of level 1 or below, 800 skeleton archers, and a level 3 undead knight hero."

Gongsun Jin.

He stood there for a long time, his expression changing back and forth, but in the end he sighed helplessly.

After completing the fourth level challenge, he already knew how terrifying the Skeleton Sea was.

The two thousand or so skeletons in the previous level were so difficult to fight, and then there were four thousand and eight hundred skeleton archers, led by an undead hero, which was completely beyond the limit of my ability to deal with it.

Instructor Nie Yang observed back and forth in the challenge space, answering the apprentices' questions from time to time, and giving them guidance on how to use their own advantages.

He doesn't mind the apprentices opening some tricks during the assessment. As long as the apprentices themselves own them, they can use them.

His mission is to train apprentices and let them grow.

Items such as relics are capital owned by the apprentices themselves, and it is only natural to use these capitals to obtain more benefits.

If possible, he would rather everyone could complete the fifth level challenge and get a lot of rewards.

After all, a large part of all the efforts made will be reimbursed by the Zhan Zhan College in the future.

If these apprentices can become talents in the future, all their efforts will be repaid many times over.

If the apprentice cannot become a talent, there will be no reward for his efforts.

But this kind of thing itself is uncertain. No one can guarantee that his apprentice will become a talent. He can only try his best to do his best.

Under his guidance, two apprentices, Gongsun Jin and Chu Zaizhong, felt that they were not strong enough and withdrew from the challenge of the fifth level.

The remaining Zhang Jishan, Cao Wenyuan and Mok Wenxi continued to challenge the fifth level. At this time, they were all making final preparations for the fifth round of challenge.

At this time, Li Qing had already turned left and right in the canyon of the challenge space for about two kilometers. After rejecting two places that felt good, he found another canyon corner.

In fact, there are corners everywhere in the canyon, but the corner we found this time is different from other corners.

First of all, the width of this corner is quite wide, about fifteen or six meters, which is just enough to put two sections of the city wall down. If you put an arrow tower around, there won't be much space.

In addition, both sides of the corner canyon are very steep, and it is impossible for skeletons to go up the canyon from the left and right and attack the archers on the wall from a high position.

The two sections of the city wall are placed at the corner. In this way, the skeleton army directly facing the city wall is only a pile at the corner. The skeleton army behind it cannot attack the defenders on the other side of the 90-degree corner. This can minimize the risk of

The strength advantage of the skeleton army.

Li Qing simulated the battle pattern after establishing defense here in his mind, and his eyes suddenly lit up.

"Absolutely awesome!"

Make a decision now and build a line of defense right here.

First, he walked to the corner, and then opened the space in his palm. The vortex quickly expanded to more than five meters, and a five-meter-long city wall came down heavily, just touching the far left side of the canyon.

Then he followed the same example and lowered the second section of the city wall to align with the first section of the city wall.

Although the ground is not very flat, and the two sections of the city wall are crooked and cannot be completely aligned, it is not a big problem. It is just a temporary city wall and will be put away after this battle.

Then place the last arrow tower on the far right, so that the gap is basically filled.

Then open the gate to the divine realm, bring out the rested troops, put the archers on the arrow towers, and the infantry on the city walls.

But this is not enough.

Li Qing thought for a while, then found two suitable flat areas about 60 meters and 100 meters behind this section of the city wall, and put down the second and third sections of the city wall.

In this way, if the front section of the city wall is breached later, you can immediately retreat to the second section of the city wall to continue defending.

The city wall is not afraid of being broken. Such a hard stone cannot be broken by a skeleton that is not even at the first level. What he is mainly afraid of is the tactics of the undead heroes.

Although there were many skeletons in the last round, there was no hero to command them, so the skeletons all swarmed forward without any tactics at all.

Now there is an undead hero commanding this round, and he will definitely use various tactics.

The Skeleton Sea has a unique siege tactic that is very terrifying, which is to use a large number of skeletons and bones to pile up under the city wall until the bones are piled level with the city wall.

At that time, the undead army can rush to the city head directly on the bones.

Therefore, it is still necessary to build two more rounds of city wall buffers, just in case.

After doing this, Li Qing took a deep breath and shouted to the sky:

"Mentor, I'm ready to start the fifth round of challenges!"
Chapter completed!
