Building the Tower of Sauron also requires level 8 psionic research skills, and at this time, there are less than 40 minutes left for the one-hour temporary skill, Mu Tian naturally did not dare to delay any longer, so Arthur immediately took the entire engineer battalion, and then under Mu Tian's personal command, he began to upgrade the turret.

When Mu Tian started to level up alone, it would take 172 hours for the turret to upgrade the Tower of Sauron, which scared Mu Tian's eyes to drift.

However, when Li Wei and Arthur's many sappers joined, the upgrade time was suddenly shortened to a little more than 13 hours, and then the 14 speed scrolls were directly completed, which was simple and easy!

Moreover, this tower of Sauron is obviously higher than the ultimate city wall, and after the tower of Sauron was built, some sappers actually increased their construction skill level at the same time.

What made Mu Tian even more speechless was that Mu Tian himself had actually improved his life skill level, and he had also improved by four levels in one go.

"System: Congratulations to the player Mu Tian, you have successfully guided and commanded the construction of the Tower of Sauron, and your psionic research skills have been raised to level 1!"

…………

"System: Congratulations to the player Mu Tian...... Level 4! ”

In this way, Mu Tian, a guy who had never learned psionic research skills, already had a fourth-level psionic research skill after the first Sauron Tower was built.

And in this way, there are two psionic research skills on Mu Tian's attribute panel at the same time, one is level 9 and the other is level 4, so Mu Tian doesn't know what kind of expression to show, but in general, this is still a good thing.

Mu Tian calculated, because the Tower of Sauron requires resources of 800,000 points to build one, and in addition to the 15 million winds required by the Shenmu Heavenly Ladder Tower, Mu Tian's remaining points can also build about 16 Towers of Sauron.

However, it is impossible for Mu Tian to smash all the remaining points into the Tower of Sauron, after thinking about it, Mu Tian decided to finally leave 3.5 million activity points for emergency, and all the remaining points will be used to build a total of 12 Towers of Sauron.

In this way, Mu Tian began the construction process like catching up with a train, upgrading the outermost twelve turrets to the Tower of Sauron one by one, and what made Mu Tian feel extremely surprised was that when he upgraded to the eighth Tower of Sauron, suddenly the tiger's body shook, and another system prompt sounded.

"System: Congratulations to the player Mu Tian, when you were exploring the construction process of the Tower of Sauron, your construction skills have reached the level of supernatural mastery, and your building skill level has been successfully raised to level 8!"

"I'm already level 8 in construction skills!" Mu Tian had some mixed feelings in his heart, just like Wei Wutianshu before, he didn't have any struggle at all, and this construction skill was already directly level 8, so he didn't feel excited at all.

Also, this level 8 construction skill is inevitably too easy to improve a little, isn't it that players with level 8 professional skills are extremely rare, and it is rare to have one in a county town, and it is respected as a grandmaster-level existence?

How does it feel so easy to get mixed up!

If Mu Tian's thoughts are known to other grandmaster players, I am afraid that he will be in the mood to jump up and stab Mu Tian to death with a knife, is this grandmaster level so easy to rise?

Which of them didn't finally have a grandmaster-level skill when their hair was gray?

That is, Mu Tian, the pervert, has successively fished out more than forty sections of the ultimate city wall, as well as twelve towers of Sauron, the top buildings in the Shenmu Continent, and the materials required for these buildings are as high as billions of billions, Mu Tian's level can be said to be completely piled up with gold leaves, if they have so many resources to supply themselves, they are afraid that they already have level 9 skills!

Well, anyway, Mu Tian's current construction skill level is the same as Li Wei's, and he is in a skill state of level 8, and when all the twelve towers of Sauron are built, Mu Tian's psionic research skills have also rushed directly to level 6.

And because psionic research skills are extremely rare and rare life skills in the whole continent, Mu Tian's level 6 psionic research skills are estimated to be in the top ten in the whole continent, and our Mu Tian is such a bull fork!

However, after the construction of the twelve towers of Sauron was completed, Li Wei suddenly told Mu Tian that he felt that he had reached the limit of level 8 construction skills, and he was only one step away from being able to have level 9 construction skills!

When he said this, Li Wei looked at Mu Tian with enthusiasm on his face, with an expression that he couldn't wait for Mu Tian to immediately reconstruct a few more Sauron Towers to upgrade him.

"Or shall we build four more towers of Sauron?" The remaining points in Mu Tian's hand are enough for the points of the four Sauron Towers, although he still wants to stay for emergencies, but if Li Wei urgently needs these buildings to break through the level 9 construction skills and become a veritable Grand Master player, then Mu Tian doesn't mind.

"No!" Unexpectedly, Li Wei shook his head and said, "The Tower of Sauron is useless to me, the skill of level 9 is a huge threshold, I have built 12 of the Tower of Sauron, and there is very little experience that can be gained, only the building that can surpass the Tower of Sauron is estimated to be able to help me and help me break through the skill of level 9!" ”

"Then let's build two more psionic cannons, maybe we can raise them to level 9!" Mu Tian squinted his eyes and said, and then immediately started the construction of the psionic cannon, but unfortunately, when the psionic cannon was built, Li Wei still only had level 8 construction skills.

"Then you just wait for the Shenmu Heavenly Ladder Tower!" Mu Tian smiled bitterly, "It seems that except for the Shenmu Heavenly Ladder Tower, it is estimated that there are no other buildings that can help you!" ”

"Good!" Li Wei nodded, there was not much disappointment on his face, but his expression was full of excitement, he would be able to become a great architectural master one day, which was something that Li Wei would never dare to imagine even five months ago!

With the completion of the construction of the psionic cannon, Mu Tian was responsible for leading the sappers to start working hard to repair the damaged first ultimate city wall.

After two waves of poisonous beasts, three sections of the ultimate city wall were destroyed, and the rest of the city walls were basically in a state of serious blood remnants, in order to quickly repair these city walls, Mu Tian had to use a lot of resources and acceleration scrolls.

And after the city wall was repaired, Mu Tian had to make all kinds of weapons to defend the city non-stop...... More than half of the previous weapons had been destroyed in the belly of the mountain, and Mu Tian had to remake them.

And considering the fragility of these weapons, Mu Tian also made thousands of extra spares, so that the 3.5 million points left behind were almost used again, leaving only about 1.5 million points, but the entire defense line of the Mu family army was also completely renewed and returned to its heyday!

"Let me sleep for a while...... At this time, Mu Tian's level 9 spiritual energy research skills also disappeared completely, Mu Tian fell exhausted on the city wall, and fell asleep in an instant, snoring shook the sky, obviously exhausted to the extreme.

Of course, Mu Tian did not forget to tell the ancient queen before going to bed that when the 59th wave of poisonous beasts attacked, he must wake him up and let him guard Mujia Village.

So, Mu Tian was so intoxicated in the dream, and he didn't know how long he had been asleep before he was woken up by the hissing of poisonous beasts!

"What! Has the 59th wave of poisonous beasts arrived? Mu Tian stood up directly from the city wall, looked at the poisonous beasts that were about to be killed under the city wall, and suddenly asked with some annoyance, "Queen, didn't I tell you that when the poisonous beasts appear, you must wake me up immediately?" Why didn't they call me when the soldiers came to the city? Have you taken my words as wind in your ears? ”

"Mu Tian, you are so tired and sleeping too soundly, I can't bear to wake you up!" The Ancient Queen replied gently.

"You ......" Mu Tian originally wanted to quarrel a few words, but seeing that the ancient queen had a very big belly at this time, those unpleasant words were held back again.

Forget it, the ancient queen also feels sorry for herself, and the situation is not too bad, the 59th wave of poisonous beasts is just coming to the city, just continue to command the battle!

"Everyone, follow me and prepare to face the 59th wave of opponents!!" Mu Tian pulled out his Vientiane broom and shouted majestically on the city wall.

It's just that what made Mu Tian feel extremely puzzled was that when he said this, the other people around him looked at him with a smile, especially Shen Moxiang, this kid laughed out loud directly.

And although the other soldiers of the Mu family army on the city wall did not smile, the hard smile on their faces could not escape Mu Tian's eyes no matter what!

"What the hell are you guys doing? What the hell are you laughing at? Mu Tian couldn't help but ask.

"It's nothing, it's just that Xiao Mutian, you are wrong, this is not the 59th wave of poisonous beasts!" Ancient Queen Road.

"Isn't this the 59th wave of poisonous beasts? So how many waves of poisonous beasts are this? Mu Tian was really stunned this time.

"This is the 61st wave of poisonous beasts, Mu Tian, you have been sleeping for 21 hours!" The Ancient Queen laughed.
