The Ancient Tree of Knowledge has endless knowledge, even if it is read by memorization, it will not be able to learn it in a hundred years, this is a huge treasure of incomparable value, if the conditions allow, Xiao Yu really hopes to be able to retreat here for a year and a half. It's a pity that the situation in Tiancheng is unknown, and it will be more dangerous to go back a minute late. I have to choose my memory, anyway, there is Xiaobai around her, even if her knowledge is not as good as the ancient tree of knowledge, it is also very rich.

Xiao Yu spent half a day memorizing hundreds of ancient recipes and learning a lot about alchemy, as well as the skills and experiences of alchemy masters. This is enough, even a small fraction of the knowledge, enough for Xiao Yu to digest for a considerable period of time and benefit for a lifetime.

Xiaobai and the other fox girls have memorized a lot of basic knowledge of magic technology, don't look at the time, but they have laid a vital foundation for the establishment and development of the Wentian Research Institute.

Xiao Yu took the fox girl back to the space ring and returned to the real world.

Presumably, time passes faster in the world of truth, and it takes more time than expected, and when it comes out, it is almost dark. The war between Wentiancheng and the Sea Clan has probably been going on for a day and a night, although I don't know how the battle is going, but I believe that with the defense of Wentiancheng, the ability of Han Kexin and Zhao Changping, plus the support of the Fire Blade Tribe, will not be broken.

Xiao Yu shouted, "Hillaria! ”

Hilaria stepped out of the distorted space, holding a staff that was very delicate and beautiful, white as jade all over, with six jasper-like leaves at the top symmetrical in pairs, stretching out to both sides, and in the middle was a huge crystal clear gem.

Xiao Yu recognized that this was the staff in the hand of the Elf King, and for some reason he gave it to Hillarya, exuding a very powerful natural power, which was definitely not an ordinary thing.

Hilaria wore a flower crown, a sackcloth in sackcloth, closed her feet, and a delicate and noble scepter, which, combined with her thrilling beauty, gave people a special feeling, and she pouted, "Come out so early?" What a waste, what a waste! Even for ordinary elves, the opportunity to enter the world of truth is rare! ”

Xiao Yu shook his head lightly and said, "My companion needs me, I really can't stay here anymore, say goodbye to the Elf King for me, and I'll go back." ”

"Okay, but forget about saying goodbye, my father has arranged for me to take you back, of course I will take you back. In addition, my father has prepared a small gift for you. Hilaria didn't wear a space ring or a ring, and there was a fluctuation in the space between the white jade-like fingers of the five-fingered Qianqian, and a ring appeared in the palm of her hand, "No, take it, this will help you." ”

How could the small gift given by Senmande be an ordinary commodity? Xiao Yu immediately thanked him and took the space ring.

Hilaria introduced: "There are some alchemy materials, a few alchemy recipes, and you can refine the potion to remove soul damage by yourself. In addition, there is a Giant Tree Guardian seed, as long as it is planted in the soil, the more energy absorbed can grow the Guardian, and the more power absorbed, the stronger it will be. The best escape dagger is for you, a trophy from the elves of ancient warfare, an epic weapon, so-so, but can help you escape danger when necessary. ”

Xiao Yu looked through it carefully, and the space rings were all fourth-level precious materials without exception, which were basically related to the soul, and they were treasures that were hard to find. There are also several copies of the thousand-year-old dryad leaves, the thousand-year-old dryad essence, the quality is far better than the hundred-year-old dryad leaves and essence that Xiao Yu got at the beginning, this is something that improves the success rate and quality of alchemy.

"Giant Tree Guardian Seed", purple lower grade, can be planted, consumes 50,000 energy points to summon the 'Giant Tree Guardian', consumes 500,000 energy points, and can be upgraded to 'Earth Guardian'.

"Escape Dagger", purple mid-grade, from the abyss world, contains an epic weapon of space power, which can cut the shackles of space and break the prohibition of magic. Collateral Skills: Imprisonment Break (Level 4), Positioning and Teleportation (Level 4).

The elven king's small gifts, any of which are hard to find, even include an epic piece of equipment with spatial attributes. The preciousness of epic weapons is enough to make a powerful fifth-order powerhouse grab their heads, and there are very few fifth-order powerhouses who can hold epic equipment, let alone rare epic weapons with spatial attributes.

"I almost forgot, my father made an engram and gave it to you, recording the use of the Book of Miracles, which should be of great help. Finally, let me tell you that the elves never fight between races easily, and my father doesn't want to interfere too much in the development of human beings, so he can only help you so much for the time being, and I hope you can lead human beings to grow in the right direction. ”

Xiao Yu said seriously: "Thank you, I will definitely keep it in mind." ”

"Okay, let's go."

Hilaria took Xiao Yu's positioning scroll, checked the spatial coordinates recorded on the scroll, she closed her eyes, held the staff with both hands, and the powerful magic power was released, and the space was torn apart violently and left here with Xiao Yu.

…………

A few hours ago, the war in Ask Heaven City had just come to an end.

Dusk is like blood, sprinkled on the surface of the same bright red lake. Thousands of corpses were soaked in the water, entrails and blood were splattered everywhere, pits and broken stones littered the area, and cracked armor and broken weapons were left on the ground.

In the half-day onslaught, the Sea Clan killed the city wall several times, but they were all blocked back, and they were never able to break through the impregnable Wentian City. Eventually, after leaving a total of 35,000 corpses on the three walls, the Sea Clan slowly retreated to the opposite side of the Silver Mirror Lake. The Sea Clan suffered heavy casualties, but with the defense and treatment of a large number of giant stone turtles and war buildings, the loss of troops was not unacceptable. When the Sea Clan retreated, the walls of Wentian City were already full of potholes, the arrow tower was destroyed by as many as seventy percent, the corpses were piled up, the blood flowed like a river, and the city towers were dyed red.

The most tragic battle was the field battle of the two major armies in the north, more than 10,000 orcs and more than 1,000 demonic beasts led by Rorom and 60,000 sea clan troops launched an earth-shattering battle in the field, and the final result was a tragic victory for the orcs who were not superior in number at all, and the number of casualties in the sea clan army reached half of the total.

After a day's war, it finally came to an end in the twilight, and the Heavenly City and the Fire Blade Tribe had more advantages on the surface, and the number of warriors lost was relatively small, while the Sea Clan was at a disadvantage, and the losses were heavy, with a loss of 60,000 combat strength. In fact, it is not true, the Sea Clan still has 150,000 troops, and the main force has not been destroyed. On the other hand, the defense of Wentian City was greatly weakened, and the orc army led by Rorom basically lost the ability to fight again after this battle.

It's just more than half a day of siege warfare, the consumption of sea clan warriors and mages is very large, at this time the retreat is to give the sea clan a chance to take a breath, the destroyed defense force of Wentian City cannot be reconstituted overnight, but the sea clan army can recover its combat effectiveness overnight, so as to launch a more fierce attack, and capture Wentian City in one breath at a smaller cost. A temporary withdrawal is a wise choice to retreat.

Han Kexin looked at the devastated ground in front of him, his brows furrowed, and he had to admit that he still underestimated the strength of a fourth-order warrior. Hundreds of orcs, thirty transformed orcs, many Kodo giant beasts, dozens of bipedal wyverns, and dozens of other monsters, a large number of arrow towers to cover, and many traps on the ground, it should have been a nirvana.

Sabah single-handedly killed more than half of the orc warriors, including nine transformed elite orcs, and also killed three Kodo giant beasts, five bipedal flying dragons, more than ten other demonic beasts, and even smashed two arrow towers, almost killing Han Kexin many times, and finally let him escape with serious injuries in a bloody way.

"It's a shame I didn't kill him. However, with the shark man being extremely serious, escaping back is no different from a crippled person, even if enough healers heal the injury, the mental strength is seriously overdrawn, and the next three to five days will not be able to continue to participate in the battle. ”

Han Kexin took a deep breath and ordered people to clean up the battlefield.

The battle statistics came out quickly.

The loss of materials is unprecedentedly serious, because the Flame Arrow Tower is a second-level arrow tower, and the consumption rate can be more than ten times more than that of ordinary arrow towers, and the two magic cannons have never stopped using them for a moment, and the energy used by the magic cannons is a spirit gem!

The soul gems were consumed like flowing water, but most of the loot was outside the city, and the soul gems were recovered and taken away by the Sea Clan in the process of fighting, resulting in the rapid reduction of the soul gems in the inventory of Wentian City and could not be replenished...... Ask the heavenly city to break itself.

Han Kexin frowned, thinking about countermeasures.

"Deputy City Lord, the reinforced orc army and the sea clan army have a battle left, and the troops have five thousand left, and they have successfully entered the city, but most of them are wounded soldiers." Zhao Changping was wounded in more than a dozen places all over his body, his armor was completely stained red with blood, and his face was also stained with blood, "We captured a large number of enemy soldiers. ”

The 5,000 orc army is not a weak force, but it is far from enough in front of the 150,000 Sea Clan army, not to mention that most of them are wounded.

Han Kexin asked, "How many Sea Clan captives are there?" ”

"Probably more than a thousand."

Han Kexin was stunned for a moment and asked, "How can there be so many captives?" ”

"Most of them are seriously injured and disabled sea clans who have not had time to be rescued by their companions, and a considerable number of them are thunder-based magic scrolls prepared by the deputy city lord and given to the corona in the lake." Zhao Changping paused and continued: "At present, there are more than a thousand Sea Clan warriors, and there are several Sea Beast captives, and the Wind Knight troops are continuing to clean up the battlefield and look for more loot and captives. ”

On the square, more than a thousand Sea Clan warriors were bound by Tian Tian's devouring vines, and while the troops of Wentian City were closely guarded, they stood on the square and waited for disposal, and from time to time, a wind knight descended from the sky, dropping a few newly captured wounded prisoners, as well as a large number of balls of light sealed with items.

The captives were not all Sea Clan warriors, there were also many injured monsters among them. Among them, there is a behemoth that is the most conspicuous, it is a blind dragon turtle, surrounded by Tian Tian's vines all over the body, the butcher stands on the turtle shell of the dragon turtle, once he finds that the dragon turtle has signs of attack, he will shoot out a black lightning bolt in his hand to split on the dragon's head, hitting its head and flesh.

"I caught a dragon turtle!"

Zhao Changping nodded, "Well, it is entirely the butcher's credit that this dragon turtle can be captured." What should be done with these captives? The Emperor said that there is a secret realm in the Dark City called the 'Skeleton Ritual Land', and it is possible to transform all of them into skeleton warriors to strengthen the defense of Wentian City, but unfortunately there are too many of them, and if all the legends pass, then the price will be too high. ”

Han Kexin mercilessly ordered: "First pick out some of the prisoners who are seriously injured and dying, or crippled, and seal them into the Resentful Spirit Tower, and the rest are locked up and planned!" The stronger the energy in the Wraith Tower, the stronger the power, which is the fastest way to increase the strength of the city's defenses! ”

"What about this dragon tortoise? The dragon tortoise is too powerful, and if it is a problem to stay in the city, the butcher must not be able to guard it all the time. ”

Han Kexin hesitated when deciding whether to kill the dragon turtle.

Du Tao suddenly ran over in a hurry and shouted, "Deputy City Lord, good news!" The news that we are being besieged by the Sea Clan army has spread, and several alien tribes have already been dispatched to join forces with Wentian City to deal with the Sea Clan! ”
