In front of the combat plane, there was a majestic city, which was about the same size as the Yansheng City, but it was built between the mountains and the surrounding mountains.

This city is the Thousand Hills Holy City, one of the thirteen holy cities of the Federation.

In fact, in the deep mountains, there are many powerful monsters, and there are also many king beasts, and the powerful monsters basically have a sense of territory, and the Thousand Mountains Holy City is established here, and the danger is higher than that of other holy cities.

It stands to reason that a city should not be established here, let alone an important thirteen-pillar city of the Federation, but in this mountain, there is the densest group of spatial gaps in the Federation, and this is the place with the most known secret realms now, and the Thousand Mountains Holy City is established here, which can guarantee the right to rule the secret realm.

The battle mecha group escorted the combat aircraft over the mountain range, and in the mountain range, there were bursts of fierce beast roars, and the sounds came one after another, and even some powerful flying monsters attacked the mecha group.

Fortunately, there are no king beasts, and the mecha guards are enough to deal with it.

After approaching the Thousand Mountains Holy City, the flying monsters that had been following the mecha group began to slowly leave. These powerful monsters all possess wisdom comparable to that of humans, and they know the strength of the defense of the Thousand Mountains Holy City, so they basically do not approach the Thousand Mountains Holy City.

The mecha team slowly stopped in front of the Thousand Mountains Holy City and began to contact the defense system of the Thousand Mountains Holy City for security detection.

Although Zheng Lao is the person in charge of this exchange student work, his own strength is not strong, so the command of the mecha team is held by a teacher from Evergreen University.

This teacher is burly and tall, he is a ninth-level general who refines the body flow, and his strength is extremely powerful, except that he can't fly, his strength is completely comparable to that of a first-level king beast.

His mission this time, in addition to leading the mecha team and protecting the students, the most important task is to protect the safety of Zheng Lao.

An alchemy master is of great importance to the Federation, those God of War Realm powerhouses are inseparable from pills, and the number of Federation Alchemy Masters is much smaller than that of the God of War Realm powerhouses, so Evergreen University will definitely not allow Zheng Lao to be in any danger this time.

"Evergreen University Mecha United, request to enter the Thousand Mountains Holy City. The commander of the Mecha Wing used a communicator to speak to the security and defense department of the Thousand Mountains Holy City.

"Please enter the security serial number. There was a response from the Thousand Mountains Holy City.

Yu Qing looked at this ninth-level warrior powerhouse, and the thoughts in his heart kept appearing.

Although he has broken through the realm of war generals, it is estimated that he is still a little suspenseful against the ninth-level war generals of the upper refining body flow, but it is impossible for the other party to kill him at all.

After all...... Yu Qing also has a few big killing weapons, like Netherworld Qi, needless to say, he doesn't even dare to touch himself, other than that...... The two mysterious weapons of Yan Yan Ring and White Bone Stick can also be used by themselves, although there is no way to completely urge them, but they can also stimulate some of the power.

In fact.

Yu Qing was not thinking about the battle now.

It's the heavenly mounds of the ninth-level generals.

The most martial artists in the Federation are the ninth-level generals, and the breakthrough of the general's realm can be described as a tribulation, difficult, difficult, difficult, especially the ninth-level refining body flow general, which is ten times more difficult than the breakthrough of ordinary generals.

Of course.

Yu Qing has the help of Life Source Blood and Taihuang Aura, and his breakthrough should be much easier, but he is thinking-

The breakthrough of the God of War Realm is so difficult, there must be many ninth-level battle generals trapped in front of this Heavenly Pier, and they do not lack the best energy stones and Taihuang aura...... The origin of the Desolate Aura is difficult to explain, and it is difficult to take it out, but the best energy stone can be said to be found from the secret realm...... There are so many ninth-level generals, if you use the best energy stones to forcibly pile up a group of war god powerhouses to come out, as your own team......

It's exciting to think about.

However, Yu Qing was just thinking about this, and there was no way to implement it for the time being, at least he didn't dare to do it until his strength was comparable to that of a strong man of the God of War.

In case a pack of white-eyed wolves comes out.

The mecha team passed the security inspection of the Thousand Mountains Holy City and drove into the Holy City.

A group of mecha flew over the bustling city and flew towards a huge academy, and at this time, Yu Qing discovered that the Eldis Academy was actually built on a big mountain.

The surface of the mountain range has been covered with metal structures, and it is estimated that the belly of the mountain has been hollowed out, and the mechs are flying in other directions, and the combat planes are parked on the tarmac of Eldis University.

After Yu Qing and the others entered the Thousand Mountains Holy City, one of the deputies beside Zheng Lao had already contacted Eldis University, and many teachers from Eldis University were waiting on the airfield to welcome the students of Evergreen University.

Zheng Lao walked off the plane with the students, and was greeted by a blonde woman with large chest muscles, this woman was about thirty years old, tall and tall, and her whole body exuded mature charm.

As soon as Zheng Lao got off the plane, and before his feet could stand firmly, this blonde shǎo fu gave Zheng Lao a big hug, and said with some excitement: "Zheng Lao, it's successful, we've succeeded." ”

"Jacqueline, pay attention. Boss Zheng struggled out of Jacqueline's arms with a grimace, and then asked, "What succeeded?"

Jacqueline's excited toes stood on tiptoe, and she said happily: "The pill recipe of the ancient pill 'Changqing Dan' that you came out of Evergreen University has successfully researched. ”

The patent for the Changqing Pill was in Changqing University, but with the alchemy technology of Changqing University, there was no way to copy this elixir, so the development of the elixir was transferred to Eldis University.

The patent is still enjoyed by Evergreen University, but if Eldis University can help Evergreen University research the elixir, then if Eldis University wants to refine and sell Changqing Pill in the future, Evergreen University will only charge a symbolic license fee of one federal currency.

Hearing the words of the two, Yu Qing was stunned, Changqing Dan was refined, this is impossible.

When did the Federation's alchemy technology become so advanced?

Old Zheng's face was suddenly full of smiles, and he said, "Has the Changqing Pill been refined, hurry up and take me to see it." ”

Jacqueline shook her head and said, "The Changqing Pill has not yet been successfully refined, but after our experiments, we have determined that the prescription you provide is accurate, which is a breakthrough. Once the prescription is accurate, the direction of our research can be established. ”

Old Zheng smiled, "Let's go, take me to your research room to have a look." ”

......

In the afternoon, Eldis University held a welcome party for exchange students.

The president of Eldis University took the stage to give a speech in person.

As for Zheng Lao and several alchemy masters from Eldis University, they did not show up, and they were probably working in full swing in the laboratory.

After the adjournment of the meeting.

Several students from Eldis University walked up to Yu Qing: "Hello students from Evergreen University, I'm Erica, we are the guides of this exchange student work, if you have anything you want to know, want to visit or want to study, you can find us, we will do our best to help you." ”

Eldis University is located in North America, and most of the students here are white, Yu Qing nodded to Erica and said with a smile: "I want to visit your latest elixir?"
