The progress is okay, the cost has been reduced by half compared to the original, and it can be used by middle-level creatures, but it is still a bit expensive, Wang Tian asked them to continue researching.

Let them use low-grade materials as much as possible, and use as much as possible if they can replace other things, reducing costs is good for the people of Xiaoqian World, and it is also good for themselves, so they don't have to worry about not being able to produce because of raw material problems.

Just like the system used by high-level beings now, due to the limitation of raw materials, it cannot be put into production in large quantities, so only a very small number of people on their side can use the system, and the price is relatively high.

After that, Wang Tian and Yun Yun went to see other places, and the progress of other projects was relatively slow, so Wang Tian asked them to have time to go into other worlds to dig up some talents.

Gong Zhen and they have been defeated by the demon race since they have the assistance of the system, even if they don't want to blow themselves up, they can't stop Gong Zhen from moving forward, and they have recovered half of the territory in just one year.

"It's cool to have system assistance, those demons must be angry." Zhongyu said excitedly.

During this time, they attacked the demons, and as soon as the demons came over and wanted to blow themselves up, they avoided them, and those demons who were hidden in the shadows wanted to sneak attack and were also discovered by the system.

The demon clan has suffered heavy losses during this time, and the God Emperor Mirror powerhouse alone has fallen eight, although they have not been able to get their corpses, but they have gained a lot, and the corpses of the demon clans in the God Emperor realm have gained a lot.

"The demons don't dare to blow themselves up easily now, the threat to us is greatly reduced, as long as it takes a while, we can drive them out." Ling Du said excitedly.

"We can't take this lightly, the demons should be thinking of a way to deal with it now, when they attack again, we must pay attention to their self-detonation formations, through the detection of the system, they have arranged a lot of formations in the defense line, the next time we attack, we will solve these formations first, and then let our people pass." Gong Zhen stood up and said.

"Let's attack with the battle formation first, and then send someone over to crack the formation, anyway, there is a system, it is easy to find the formation base, and if you pull out the formation base directly, the formation will be broken, there is nothing to worry about." The Golden Sable Ancestor said disappreciatively.

"It's better to be careful, the demons are not afraid of losses, but we are afraid, they have the support of the entire universe behind them, we only have two worlds, and we can't be careless just because the demons can't fight back for the time being." Gong Zhen explained.

"Then why don't we attack it now? Why wait for the demons to arrange us before we go over? Golden Sable Ancestor asked.

"Golden Sable Daoist, you also know how much it costs to use the battle array, we don't think there is anything if the God Emperor Mirror recovers relatively quickly, but the recovery below the God Emperor Realm is not so fast, we have to wait for them to almost recover before we can attack again." Tiandan Ancestor stood up and explained.

At this time, the Golden Sable Ancestor remembered that this was not the Nine Heavens Divine Domain, and the powerhouses of the God Emperor Realm brought by him were limited, and they were all dispatched before, but they have not recovered yet, and if they are dispatched again, they will not be on their own side, and the benefits will be much less.

"Jin Mink Daoyou also wanted to solve the demon clan in a hurry, but he didn't think about it in a hurry. There are still a few loopholes in the formation, let's improve it! "Gong Zhen stood up to relieve the siege of the Golden Sable Ancestor.

No one objected to Gong Zhen's suggestion, because the battle array was well established before, once a God Emperor Mirror Demon Clan was suppressed by self-detonation, and did not cause any damage to their side, so now they pay more attention to the battle array.

……………………………………………………………………………

"Lord Demon Emperor is angry again, this time the loss is so big, and let them counterattack to regain so much territory, and we can't attack again, if this continues, Lord Demon Emperor will definitely replace us."

"He doesn't have a backache when he stands and talks, our side desperately blew himself up, but the enemy seems to know in advance, and he dodges directly, and their battle formation is getting more and more powerful, no one dares to approach, let alone take the initiative to attack, what else can we do but defend? If he's really that good, let him come. ”

The Demon Emperor is one of the Supreme Venerables, not everyone obeys him, and there are some who are now on the side of other Supreme Venerables, so there is no need for them to give the Demon Emperor face.

The others got used to it and didn't say anything about it because he didn't respect the Demon Emperor.

"No matter what, we belong to him now, and now it is his people who have fallen the most, and it is normal for him to be angry, but we can't do useless work."

"Yes, we should plan how to deal with their attack, now they stop attacking because they want to recover, and when they recover, they will attack again."

"Take advantage of this time to improve the battle formation, otherwise we will be completely defeated next time."

"It's a pity that we don't have many God Emperors who can enter that world, otherwise it won't take long for us to all of them to be wiped out."

"Needless to say, let's solve the current predicament first!"

"In addition to the battle array, we also need to make another arrangement, Lord Demon Emperor has formulated a plan for us, and we will execute it according to this plan."

"What's the plan?"

"It's ............"

"As long as the plan is successful, they will have no return, and no one will be able to stop us at that time......"

"Then let's do it right away."

The plan of the demon clan Gong Zhen is not known to them, they are constantly improving the battle formation, and those God Emperors who have not fully recovered will also have time to practice, with Gong Zhen and them to improve, the rest of the people just need to follow Gong Zhen's guidance to do it.

Everything went smoothly, it took a year for Gong Zhen and them to perfect the battle formation, and the others were almost recovered, and Gong Zhen and they got together again to discuss how to attack.

"The battle formation has been perfected, and our men have recovered. This time we raided, we should be able to drive the demons out. ”

"This time, we must not allow them to have time to blow themselves up, and we must catch a few more God Emperor Mirror Demons."

"Then let's plan the attack. And in order to avoid accidents, we have to keep some people on the side of the defense......"

Gong Zhen and they directly launched an attack after they discussed, and at the beginning, the demons were defeated and retreated, with countless casualties, and basically there was no power to fight back.

It's just that after going deeper, there was a sudden accident, and Gong Zhen suffered heavy losses on their side...............
