At the last pass of the middle road of the ruins, Lin Chen faced the flock of strange birds at high altitudes that had become a hidden danger, and resolutely used the metal hydrogen bomb, one of the ultimate weapons of humans on Earth.

The moment before the small sun appeared at a high altitude, Lin Chen used teleportation to move to a high altitude two hundred meters away and instantly opened the fourth level of protection to the maximum.

Because of preparations in advance, after the bomb exploded, when the strong storm hit Lin Chen, it only made Lin Chen's body roll for a few times, without causing any damage to Lin Chen.

Taking advantage of this opportunity, Lin Chen detonated another medium-sized metal hydrogen bomb at a new location. So before the light of the small sun completely disappeared last time, a new small sun appeared in the sky again.

When the little sun lit this time, Lin Chen's teleportation cooling time had not passed. He hid in the seed world before the bomb exploded.

The seed world time was thirty seconds, and the outside world time was three seconds later, Lin Chen estimated that the maximum power of the bomb had already spread out and appeared in the outside world again.

At this time, everyone on the ground turned their heads and closed their eyes to avoid the stimulation of the strong light of the small sun, and did not notice Lin Chen's appearance at all.

Lin Chen had already passed the teleportation cooling time in the seed world, so he took this opportunity to teleport to another direction.

With this operation, six small suns were lit up in the sky in a row.

After six explosions, Lin Chen did not continue to detonate the bomb. These six explosions basically included all the strange birds gathered in the sky above Emperor Liu in the attack range.

After the explosion, about half of the monster birds flew out of ashes, and more than 30% of the monster birds were severely injured and no longer had combat power in a short period of time. The remaining 20% ​​were also injured on their bodies, and their combat power was greatly reduced.

The troubles caused by the strange bird to Emperor Liu can be almost negligible.

"Continue to move forward and take this last pass." Lin Chen calmly landed on the ground, facing the eyes of his subordinates, he waved his hand and said with a light wave.

The subsequent war completely followed the previous development process. Lin Chen led the top masters with the powerful assistance of Emperor Liu to slowly clear the land-mounted monsters at the back of the checkpoint, and finally started to deal with the monster birds at the high altitude.

This time, when dealing with the monster birds, the monster birds had learned a certain lesson, and their distance was scattered relatively large. Lin Chen was furious and exploded three giant metal hydrogen bombs, which killed all the remaining monster birds.

The last three explosions made the entire ruins slightly shake, and also made everyone in the Sirius Army troops on the ground and the exploration teams on other roads stunned.

It can be said that in order to achieve his goal, Lin Chen no longer has to consider too many sequelae.

But saying that is the case, Lin Chen actually knew that all the things he did could be explained in an apparent way. But there is a little difficult explanation for how he avoids the explosion center.

But what Lin Chen thought was that he could use the magical props he had obtained from the ruins before to make excuses. As for what magical props it was, I'm sorry, Lin Chen has no obligation to tell you.

After the last three small suns flashed, it indicates that the Sky Wolf Army has completely opened up the middle road of the ruins and jungle.

The Tianlang Army took the lead in passing the level!

Looking at the ancient buildings close to Chi Chi, all the soldiers of the Tianlang Army showed extremely excited expressions on their faces.

This treasure that had been buried for many years finally opened its veil in front of them! All the soldiers of the Tianlang Army looked at Lin Chen, waiting for Lin Chen to issue an order to march to find treasure.

The last few explosions were obviously close to the building part outside the jungle. It was obvious that everyone could see that the Sky Wolf Army had passed the level.

On other paths in the jungle, each team was still fighting bloody battles at the fourth level. Seeing that the Sky Wolf Army had passed the level, the leaders of each team had a gloomy face. With deep doubts and anxiety, these leaders repeatedly urged their subordinates to accelerate their breakthrough.

They cannot do it without speeding up, because the Tianlang Army has passed the clearance. The buildings behind the gate have not been divided into ownership in advance. If the Tianlang Army has finished exploring the buildings behind the middle road, it is very likely that they will explore the buildings behind the gate they are facing. The Tianlang Army may also advance directly to the main peak or two side peaks in the distance.

No matter how the Tianlang Army chooses, it will get the greatest benefit. How can this not make people in other teams anxious?

As the speed of advancement accelerates, casualties of each team immediately begin to amplify. There is no way, because the combat power of humans on Earth is generally much weaker than that of monsters guarding the gate. If you want to speed up the breakthrough, you can only fill in the lives of humans.

Lin Chen did not think about the situation of other teams. He made great efforts and finally led the Tianlang Army troops to pass the first pass. Now, it is time for the Tianlang Army to harvest.

"Yaya, Wenwen, Sword Girl..., you each lead a team of people and explore these buildings in eight directions."

Lin Chen calmly looked at the quietly standing building complex and began to arrange troops.

"Brother, it seems that the fastest teams on other roads will take three or four hours to break through the last barrier. We have left a lot of time. After we explore the buildings in front of us, should we go directly or turn to the buildings behind the other teams?" Lin Ya asked Lin Chen excitedly.

"Forget it, we won't go to compete with them for food. The best thing must be on the main peak and the two side peaks." Lin Chen looked up at the three particularly prominent peaks in the distance, pondered for a moment and said.

"Okay. Just let them get some benefits, so as not to make any noise." Lin Ya nodded and said.

After a little busyness, Lin Ya and others took more than a thousand men and horses and left. Lin Chen himself also took hundreds of soldiers and moved forward directly.

The exploration of the ruins of Ziyun Mountain by the Tianlang Army has officially begun.

However, at the beginning of the exploration, Lin Chen discovered a huge problem. Since these buildings in the Ziyun Mountain ruins are quite intact, their defensive formations are also in relatively good condition.

All the soldiers of the Tianlang Army who walked on their way found that the strong defense of the doors of the ordinary buildings they faced was even higher than the defense level of the last main building of the ruins they had explored in the past.

The situation of the Tianlang Army is a little awkward now.

You should know that as the doomsday deepens, the higher the defense level of the ruins that appear later. As early as the third or fourth year of the doomsday, the defense of the ruins that appear cannot be broken with explosives, but must be broken with power with cultivators on earth who know a little knowledge of formation.

Because of the ruins, the Tianlang Army also strengthened the cultivation of those with talented formations in the past few years. In order to cultivate these special abilities, the Tianlang Army has paid huge resources.

After accumulating over the years, the Tianlang Army has no less than 30 cultivators who specialize in formation and have certain attainments. After Lan Ling'er joined Weicheng, these cultivators received special guidance from Lan Ling'er.

Although Lan Ling'er is not good at formations in the world of cultivation, she is more than enough to guide the earth cultivators who have become monks halfway through formation knowledge and literacy. As a result, the formation cultivators in the Tianlang Army are basically not weaker than those in the Chinese group of formation cultivators.

However, when these formation practitioners faced the formation defense of ordinary buildings in the ruins in front of them, they were like mice pulling turtles, and could not find a place to start to crack.

This is the case for all the eight-way exploration teams assigned by Lin Chen. No formation cultivator is sure to quickly break the defense of the gate wall. Most formation cultivators are blinded by their eyes, and a very small number of formation cultivators who can find a little vein also need a lot of time to make detailed calculations.

In this way, although the Tianlang Army first broke through the barrier and faced the treasure, it was temporarily unable to enter.

After waiting for a while, Lin Ya saw that she could not make contributions for the moment, she ran to others to check. After seeing this situation everywhere, she came to Lin Chen.

"Brother, this won't work. If you can't open the room for a long time, other teams will soon catch up. With the support of cultivators from other worlds, they will definitely not be as difficult as us. After all, the knowledge of formations of cultivators from other worlds is not comparable to our formation cultivators. Brother, think of a solution quickly." Lin Ya said anxiously.

No matter what difficulties Lin Ya encounters now, as long as her brother is by her side, she will leave all the problems to her brother. In Lin Ya's heart, her brother is always omnipotent. Even though the situation in front of her has obviously exceeded the range of knowledge that Lin Chen can usually get in touch with, Lin Ya still wishes to think that her brother can do it.

"Yaya, don't worry. Brother is trying to figure out a solution." Lin Chen frowned and looked at the warrior who was studying the first defensive formation on the door, and said softly to Lin Ya.

Lin Chen was a little regretful at this time that he didn't spend some effort on the formation when he was in the world of cultivation. Otherwise, he wouldn't be so passive now.

The level of the ruins in front of me is obviously higher than that of all the ruins before. The defensive formations of its ordinary buildings are actually stronger than the formations of the main buildings of the ruins in the past. The explosives are basically no longer effective in front of such formations.

If you have to pile up hundreds of tons of explosives and thousands of tons of explosives to break the formation, you may be able to break the formation. But that is a bit exaggerated after all. That will probably lead to the indecision that will cause the room to be completely damaged, even if you can calculate the amount of explosives, where can you get so much explosives in a short time?

Lin Chen didn't get so much explosives. He just wanted to waste the spirit stones and directly paid the spirit stones to transform the source of the world in the seed world.

However, there is a huge mistake that cannot be concealed by doing this. That is, Lin Chen cannot explain the source of so many explosives. This will increase the chance of Lin Chen's biggest secret being exposed.

Before entering the ruins, Lin Chen had a conclusion in his mind. During this exploration, he would rather give up the treasures he might get than let his secrets be revealed.

The methods he used to quickly break through the barrier can basically be explained reasonably. Although the reason may be a bit far-fetched, it can still stand firm.

But now he can never take out countless explosives.
